Embodiments for Carrying out the Invention

[0011] Hereinafter, embodiments will be described in detail with reference to the drawings as appropriate. However, detailed descriptions that are more than necessary may be omitted. For example, detailed descriptions of well-known matters and duplicate descriptions of substantially the same configurations may be omitted. This is to avoid making the following description unnecessarily redundant and to facilitate the understanding of those skilled in the art. The inventor provides the accompanying drawings and the following description so that those skilled in the art can fully understand the present disclosure, and does not intend to limit the subject matter described in the claims thereby.

[0012] (Embodiment 1) In Embodiment 1, as an example of the imaging system according to the present disclosure, a camera system that can be held by a user with both hands will be described.

[0013] 1. Configuration FIG. 1 is a diagram for explaining a camera system 1 according to Embodiment 1 of the present disclosure. The camera system 1 of the present embodiment includes, for example, a digital camera 10 and two grip devices 3L and 3R. The digital camera 10 of the present embodiment is, for example, of an interchangeable lens type, and includes a camera body 11 and an interchangeable lens 12 that is detachably attached to the camera body 11. Hereinafter, the grip devices 3L and 3R may be collectively referred to as "grip device 3". The number of grip devices 3 in this system 1 is not limited to two, and may be one or three or more.

[0014] FIG. 1(A) illustrates a state in which each grip device 3 is attached to the digital camera 10 in this system 1. FIG. 1(B) illustrates a state in which each grip device 3 is removed from the digital camera 10 in this system 1.

[0015] The digital camera 10 of this embodiment is a box camera used by connecting various external devices to, for example, a box-shaped camera body 11. The external shape of the camera body 11 is set to facilitate the attachment of various external devices or assembly into equipment such as a camera rig. The digital camera 10 and the camera body 11 are examples of imaging devices in this embodiment.

[0016] Hereinafter, the optical axis direction of the interchangeable lens 12 will be defined as the Z direction, the horizontal direction perpendicular to the Z direction in the digital camera 10 will be defined as the X direction, and the vertical direction perpendicular to both the Z and X directions will be defined as the Y direction. Furthermore, the +Z side of the camera body 11 to which the interchangeable lens 12 is attached will be referred to as the front, and the opposite -Z side will be referred to as the back. In addition, the +X side may be referred to as the left side, the -X side as the right side, the +Y side as the top, and the -Y side as the bottom.

[0017] The camera body 11 of this system 1 is configured such that two grip devices 3L and 3R can be detachably attached to both the left side (+X side) and the right side (-X side), as shown in Figures 1(A) and (B). Each of the grip devices 3L and 3R is an example of an input device that the user holds in their hand to operate the digital camera 10.

[0018] According to this system 1, the user can easily grasp the grip devices 3L and 3R on both sides of the camera body 11 with their left and right hands respectively, allowing them to take pictures and perform other actions in a stable two-handed grip. Furthermore, by making each of the grip devices 3L and 3R detachable, this system 1 allows the user to use the digital camera 10 in various ways, not limited to the two-handed grip described above, such as one-handed gripping or mounting it on a camera rig.

[0019] 1-1. Digital Camera Configuration Figure 2 is a diagram illustrating the configuration of the camera system 1 according to this embodiment. Figure 2 illustrates the internal configuration of the camera body 11 and one grip device 3L of the digital camera 10 in this system 1.

[0020] In the digital camera 10 of this embodiment, the camera body 11 includes, for example, a mount 120 for an interchangeable lens 12, an image sensor 140, an operation unit 150, an image processing unit 160, a buffer memory 170, and a camera control unit 180. Furthermore, the camera body 11 includes a flash memory 130, a card slot 190, a display monitor 210, and mounting parts 2L and 2R to which each grip device 3L and 3R can be attached. Hereinafter, the mounting parts 2L and 2R of the camera body 11 may be collectively referred to as "mounting part 2".

[0021] The interchangeable lens 12 includes a zoom lens, a focus lens, an optical system such as an aperture, and a drive unit. The zoom lens is a lens for changing the magnification of the subject image formed by the optical system. The focus lens is a lens for changing the focus state of the subject image formed on the image sensor 140. The zoom lens and focus lens are composed of one or more lenses.

[0022] The drive unit of the interchangeable lens 12 includes a configuration for driving each part of the optical system, such as the focus lens. For example, the drive unit for the focus lens includes a motor and moves the focus lens along the optical axis of the optical system based on the control of the camera control unit 180. The configuration for driving each part of the optical system in the drive unit of the interchangeable lens 12 can be realized with a DC motor, a stepping motor, a servo motor, or an ultrasonic motor.

[0023] The mount 120 is a mounting part for detachably attaching the interchangeable lens 12 to the camera body 11. The mount 120 includes an interface circuit for various data communications between the camera body 11 and the interchangeable lens 12.

[0024] The image sensor 140 captures an image of a subject incident through the optical system of the interchangeable lens 12, for example, and generates RAW data. The RAW data is an example of RAW format image data corresponding to the state of the imaging result by the image sensor 140. The RAW data includes information on the amount of light exposed to each pixel in a Bayer array, for example, and shows the image of the imaging result. The image sensor 140 performs the image capture operation for each frame that constitutes a video, for example. The image sensor 140 is an example of an imaging unit in this embodiment.

[0025] The image sensor 140 generates RAW data of a new frame at a predetermined frame rate (e.g., 30 frames / second). The timing of RAW data generation and the operation of the electronic shutter in the image sensor 140 are controlled by the camera control unit 180. The image sensor 140 can use various image sensors, such as a CMOS image sensor, a CCD image sensor, or an NMOS image sensor.

[0026] The operating section 150 is a general term for operating components that receive operations (instructions) from the user. The operating section 150 includes buttons, levers, dials, switches, etc. that receive user operations. Specific examples of the operating section 150 will be described later.

[0027] The image processing unit 160 performs predetermined processing on the RAW data output from the image sensor 140 to generate image data of the shooting result. The image processing unit 160 may, for example, perform processing for development, or generate an image for display on a display monitor 210 or the like. Examples of predetermined processing include, but are not limited to, debayering, white balance correction, gamma correction, YC conversion, electronic zoom processing, compression processing, and decompression processing. The image processing unit 160 may be composed of hardwired electronic circuits, or it may be composed of a microcomputer or processor using a program.

[0028] The buffer memory 170 is a recording medium that functions as work memory for the image processing unit 160 and the camera control unit 180. The buffer memory 170 is implemented using DRAM (Dynamic Random Access Memory) or the like. The flash memory 130 is a non-volatile recording medium. Each memory 130 and 170 is an example of a storage unit in this embodiment.

[0029] The camera control unit 180 controls the overall operation of the digital camera 10. The camera control unit 180 uses the buffer memory 170 as work memory during control operations and image processing operations.

[0030] The camera control unit 180 includes a CPU or MPU, and the CPU or MPU executes a program (software) to realize a predetermined function. The camera control unit 180 may also include a processor consisting of dedicated electronic circuits designed to realize a predetermined function, instead of a CPU or the like. In other words, the camera control unit 180 can be implemented with various processors such as a CPU, MPU, GPU, DSU, FPGA, or ASIC. The camera control unit 180 may consist of one or more processors.

[0031] The card slot 190 can accommodate a memory card 200 and accesses the memory card 200 based on control from the camera control unit 180. The digital camera 10 can record image data onto the memory card 200 and read recorded image data from the memory card 200. The card slot 190 may be provided to accommodate multiple (e.g., two) memory cards 200 simultaneously. The memory card 200 can be, for example, an SD card, an XQD card, or a Cfexpress card.

[0032] The display monitor 210 is an example of a display unit (and therefore an example of an output unit) that displays various information. For example, the display monitor 210 displays an image (through image) represented by image data captured by the image sensor 140 and processed by the image processing unit 160. The display monitor 210 also displays a menu screen, etc., for the user to make various settings for the digital camera 10. The display monitor 210 can be configured, for example, as a liquid crystal display device or an organic EL device.

[0033] Mounting section 2 is an example of a connection section for detachably attaching the grip device 3 to the camera body 11. In the example shown in Figure 1(B), each mounting section 2L and 2R is provided on the ±X side of the camera body 11 so as to be able to fix the respective grip devices 3L and 3R. For example, as shown in Figure 2, the camera control unit 180 inputs and outputs signals to the connected grip devices 3L and 3R via each mounting section 2L and 2R.

[0034] Each mounting section 2 includes a mechanism for mechanically fixing the grip device 3 and a connection circuit for electrically connecting the grip device 3 and the camera body 11. The digital camera 10 of this embodiment is configured to be powered from the grip device 3 via the mounting section 2, for example. For example, the connection circuit of the mounting section 2 may conform to a predetermined communication standard such as USB. The mounting section 2 may also be connectable to an external device other than the grip device 3. The digital camera 10 of this embodiment may be powered from an external power source other than the grip device 3 using the mounting section 2 or various alternative configurations.

[0035] The digital camera 10 of this embodiment is not limited to the above-described configuration example and may have various configurations. For example, in the digital camera 10, an external display device may be used instead of, or in addition to, the display monitor 210. As an example of the output section in this case, the camera body 11 of the digital camera 10 may be equipped with an interface circuit that outputs a video signal to an external electronic device in a predetermined signal standard such as HDMI or SDI.

[0036] Furthermore, the digital camera 10 of this embodiment may be equipped with various interface circuits that perform wired or wireless communication with external devices using a predetermined communication standard, in addition to communication of video signals. The predetermined communication standard includes, for example, IEEE 802.11, Wi-Fi, Bluetooth, etc. Such interface circuits are examples of connection or output sections in the digital camera 10 of this embodiment.

[0037] 1-2. Configuration of the gripping device Figure 2 illustrates the internal configuration of one of the grip devices 3L and 3R on both sides, but each grip device 3L and 3R can employ a similar internal configuration. Furthermore, the external configuration of both grip devices 3L and 3R is, for example, symmetrical (see Figures 1 and 3).

[0038] Such a grip device 3 includes, for example, a mounting section 31, an operating section 32, a grip control section 33, and a storage section 34, as shown in Figure 2. Furthermore, a battery 30 can be detachably mounted in the grip device 3, for example, so that it is housed inside. The grip device 3 has, for example, a roughly U-shaped cross-section that is convex on the front side (+Z side) in an XZ cross-section, and is configured with an external shape that is easy for the user to grasp (see Figure 1).

[0039] The battery 30 supplies power to drive the digital camera 10 and the grip device 3. Power from the battery 30 is supplied to the digital camera 10, for example, via the mounting part 31. The battery 30 may be, for example, a dry cell battery or a rechargeable battery. Alternatively, the digital camera 10 may be supplied with power from an external source via a power cord.

[0040] The mounting portion 31 is an example of a connection portion to which the grip device 3 can be detachably attached to the camera body 11. The mounting portion 31 includes, for example, a mechanism that mechanically engages with the mounting portion 2 of the camera body 11 (e.g., a fixing screw), and a connection terminal that electrically connects to the camera body 11 (e.g., a USB terminal). The connection terminal of the mounting portion 31 may be shared for signal input / output and power supply, or it may include separate terminals.

[0041] The operation unit 32 includes, for example, operating members such as switches and buttons provided on the exterior of the grip device 3. When the grip device 3 receives an operation from the user via the operation unit 32, it transmits a signal corresponding to the user operation to the camera body 11 via the mounting unit 31. Details of the operation unit 32 will be described later.

[0042] The grip control unit 33, including, for example, a CPU, controls the operation of the entire grip device 3. The grip control unit 33 reads data and programs stored in the memory unit 34, performs various calculations, and realizes various functions. For example, the grip control unit 33 controls data communication between the grip device 3 and the camera body 11. The grip control unit 33 is not limited to the above and can be implemented with various processors, similar to the camera control unit 180.

[0043] The memory unit 34 is a recording medium that stores data and programs necessary to realize the functions of the grip control unit 33, and is composed of, for example, flash memory. The memory unit 34 may also include RAM, and may temporarily store data and function as a work area for the grip control unit 33.

[0044] 1-3. About the control panel Specific examples of the operating sections 150 and 32 of the digital camera 10 and grip device 3 in this system 1 will be explained using Figure 3. Figure 3 is a diagram illustrating the rear view of the camera system 1 of this embodiment. In the example in Figure 3, grip devices 3L and 3R are attached to both sides of the camera body 11 in this system 1.

[0045] Figure 3 shows an example of the operation unit 32 of the grip device 3, which includes a joystick 320, a directional key 321, and several function buttons 322-324. Also shown is an example of the operation unit 150 of the camera body 11, which includes a touch panel 155, a SET button 151, a DISP button 152, a Q button 153, and a back button 154. Each operation unit 32 and 150 transmits various instruction signals to the camera control unit 180 upon receiving user input.

[0046] The joystick 320 is an operating component that allows the user to tilt and press the stick member located in the center in the up, down, left, right, and diagonal directions between these directions. By pointing the joystick 320 in any direction and using directional controls, the user can select various items displayed on the display monitor 210 or move the cursor. The joystick 320 can accept user input with adjustable degrees of tilting or pressing in various directions.

[0047] The directional keys 321 include push-button sections corresponding to the up, down, left, and right directions, and can be operated in accordance with the directional control of the joystick 320. A push-button corresponding to the pressing operation of the joystick 320 may be provided in the center of the directional keys 321.

[0048] Function buttons 322-324 are push-buttons to which various functions of the digital camera 10 can be pre-assigned. The operating components to which the various functions of the digital camera 10 can be assigned are not limited to these, and can also be assigned to, for example, the joystick 320 and the directional keys 321.

[0049] The SET button 151, DISP button 152, Q button 153, and back button 154 are push-buttons used, for example, to operate the settings menu. Each of the buttons 151 to 154 is not limited to the back of the camera body 11, but may also be provided on the top or bottom of the camera body 11, for example. Each of the buttons 151 to 154 may function as a function button in various operating modes.

[0050] When the digital camera 10 is in shooting mode or playback mode, if the SET button 151 is pressed by the user, the camera control unit 180 displays a menu screen on the display monitor 210. The menu screen is for setting various conditions for shooting / playback. When the SET button 151 (or joystick 320) is pressed while a setting item for various conditions is selected, the camera control unit 180 confirms the setting of the selected item.

[0051] The touch panel 155 is positioned superimposed on the display screen of the display monitor 210 and detects touch operations on the display screen by the user's finger. This allows the user to perform operations such as specifying areas of images displayed on the display monitor 210 and making various selections on menu screens. Virtual buttons displayed on the touch panel 155 may also function as function buttons.

[0052] 2. Operation The operation of the camera system 1, configured as described above, will be explained below.

[0053] The digital camera 10 of this embodiment has multiple functions (hereinafter also referred to as "camera functions"), such as various shooting functions that the user uses to take desired images. Each camera function can be used by the user by operating an operating member, for example, on the grip device 3, after it has been assigned to that operating member. This system 1 provides flexible settings for assigning camera functions according to various user usage patterns, such as how the various grip devices 3L and 3R are attached to the digital camera 10. The operation of this system 1 will be described in detail below.

[0054] 2-1. Overall Operation The overall operation of the digital camera 10 in this system 1 will be explained using Figure 4A.

[0055] Figure 4A is a flowchart illustrating the operation of the digital camera 10 in this system 1. The processes in the flowchart illustrated in Figure 4A begin, for example, when the power is turned on with one or more grip devices 3 attached to the camera body 11. Each process in this flowchart is executed, for example, by the camera control unit 180 of the camera body 11 in the digital camera 10.

[0056] First, the camera control unit 180 detects the grip device 3 attached to the camera body 11 and determines whether the camera body 11 has grip devices 3L and 3R attached to both sides, or whether the grip device 3 is attached to one side (S1). The processing in step S1 can be carried out, for example, by detecting the energization of each mounting part 2R and 2L, or by sending and receiving signals between the camera control unit 180 and the grip control unit 33.

[0057] The camera control unit 180 sets the assignment of camera functions for the grip devices 3L and 3R on both sides if the camera body 11 is equipped with grip devices 3L and 3R on both sides (YES in S1) (S2). The camera control unit 180, for example, displays a predetermined setting screen on the display monitor 210, and accepts user operations from the various operation units 150 and 32 to set the assignment of camera functions for the grip devices 3L and 3R on both sides (S2).

[0058] In this system 1, for example, it is possible to achieve a function assignment that enables natural operation when the user operates the digital camera 10 using each grip device 3, or a function assignment that makes it easy for the user to think of the corresponding camera function, from an ergonomic perspective. For example, in this system 1, a specific camera function is assigned to the operation of using each grip device 3L and 3R with both hands simultaneously. With such simultaneous operation with both hands (details will be described later), the user can operate the digital camera 10 intuitively and reduce the likelihood of accidental operation.

[0059] Furthermore, in this system 1, camera functions can be assigned not only to the simultaneous operation of both hands as described above, but also to various operations of the grip devices 3L and 3R on both sides. In addition, this system 1 can also use pre-saved setting information for function assignment. Details of function assignment in step S2 will be described later (see Figures 4B to 4C).

[0060] On the other hand, if the camera body 11 has the grip device 3 attached to one side (NO in S1), the camera control unit 180 assigns functions to the various operating members on the attached grip 3 (S3). For example, similar to step S2, the camera control unit 180 displays a settings screen on the display monitor 210, receives various user inputs with the various operating units 150 and 32, and performs settings according to the user's instructions (S3). In steps S2 and S3, functions may be assigned not only to the operating members on the grip device 3, but also to the operating members on the digital camera 10.

[0061] The camera control unit 180 applies the function assignment set in step S2 or S3 to the system 1 and stores, for example, setting information indicating the function assignment setting in the buffer memory 170 (S4).

[0062] Subsequently, during various operations of the system 1, the camera control unit 180 receives user input via various operating members in the operating units 150 and 32 of the system 1 (S5).

[0063] When a user operation is input to one of the operating components (YES in S5), the camera control unit 180 determines, for example, whether or not there is a camera function corresponding to the input user operation, based on the function assignment setting information (S6).

[0064] The camera control unit 180 controls the digital camera 10 to execute the camera function corresponding to the input user operation (YES in S6) (S7).

[0065] On the other hand, if the camera control unit 180 does not have a camera function corresponding to the input user operation (YES in S6), it returns to step S5, for example, without executing the camera function as in step S7.

[0066] The camera control unit 180 terminates the processing shown in this flow after, for example, executing a camera function corresponding to user operation (S7). After that, the camera control unit 180 may repeat the processing from step S1 onwards, or it may omit the processing from steps S1 to S4 and repeat the processing from step S5 onwards. For example, steps S1 to S4 may be omitted if there is no change in the mounting state of the grip device 3.

[0067] According to the above process, in this system 1, camera functions are assigned according to the state in which the various grip devices 3L and 3R are attached to the digital camera 10 (S1) (S2, S3). This makes it easier for the user to use the various camera functions depending on whether they are using this system 1 with both hands or with one hand.

[0068] 2-2. Simultaneous operation with both hands For example, when using the grip devices 3L and 3R on both sides (YES at S1 in Figure 4A), the user can utilize the camera function by operating both hands simultaneously (S5-S7). A specific example of this case will be explained using Figures 5-6.

[0069] Figure 5 shows an example of the setting information D1 for function assignment during simultaneous operation of both hands in this system 1. In this example, multiple functions for crop shooting of the digital camera 10 are assigned to various simultaneous operations on the joystick 320 of the left-hand grip device 3L and the joystick 320 of the right-hand grip device 3R (S2 in Figure 4A).

[0070] Figure 6 is a diagram illustrating the crop shooting function in this system 1. Cropping is a shooting method that changes the recording range, i.e., the range that is cropped out for use in recording the image data of the shooting result, within the shooting range of the digital camera 10, such as the entire pixel range of the imaging surface of the image sensor 140. Cropping is useful, for example, in high-resolution and wide-angle shooting conditions such as 8K.

[0071] The setting information D1 shown in Figure 5 assigns the operation of tilting each joystick 320 in a predetermined direction to the functions of zoom in, zoom out, panning in various directions, and switching between portrait and landscape orientations during crop shooting (S4 in Figure 4A).

[0072] For example, if the user tilts the left-hand joystick 320 to the left and the right-hand joystick 320 to the right (S5), the camera control unit 180 refers to the setting information in Figure 5 (S6) and executes the zoom-in function (S7). The zoom-in function for cropped shooting is performed by reducing the recording range within the shooting range, for example, as shown in Figure 6(A).

[0073] Furthermore, in this example, contrary to the zoom-in operation described above, if the user tilts the left-hand joystick 320 to the right and the right-hand joystick 320 to the left (S5), the camera control unit 180 executes the zoom-out function (S7). The zoom-out function for crop shooting is performed by expanding the recording range within the shooting range, for example, as shown in Figure 6(B).

[0074] With the above-described simultaneous two-handed operation function assignment, the user can perform operations such as widening or narrowing the distance between the right-hand joystick 320 and the left-hand joystick 320 to execute the zoom in / out function, providing an intuitive user experience. This simultaneous two-handed operation is not limited to zoom in / out for crop shooting; instead, the function of zooming in / out for optical zoom may be assigned to it.

[0075] Furthermore, in the example shown in Figures 5 and 6, if a user input is received to point both joysticks 320 in the same direction within the up, down, left, and right directions (S5), the camera control unit 180 executes a pan function along that direction in crop shooting (S7). The pan function in crop shooting is performed by translating the recording range in a specific direction within the shooting range, as shown in Figure 6(C), for example.

[0076] This function assignment allows users to intuitively operate the pan function, and also reduces malfunctions of the pan function compared to, for example, assigning the pan function to a user operation of pointing one joystick 320 in one direction. For example, even if a user accidentally tilts one joystick 320, the camera control unit 180 can be prevented from executing the pan function when the assignment is set as shown in Figure 5 (NO at S6). In other words, the function assignment for simultaneous operation with both hands in this system 1 effectively prevents the execution of camera functions due to accidental operation on one side.

[0077] Furthermore, in the example shown in Figures 5 and 6, when a user input is received to point one joystick 320 upwards and the other joystick 320 downwards (S5), the camera control unit 180 executes the vertical / horizontal switching function (S7). The vertical / horizontal switching function in crop shooting is performed by switching the longitudinal direction of the recording range between the horizontal and vertical directions of the shooting range, as shown in Figure 6(D), for example. For example, a vertical image with the longitudinal direction of the recording range set to the vertical direction is useful for display on smartphones and the like.

[0078] As described above, the assignment of various functions for simultaneous two-handed operation in this system 1 allows the user to intuitively operate the digital camera 10 while holding it with both hands, making it easier to use various camera functions.

[0079] In the case of simultaneous operation with both hands as described above, the camera control unit 180 may control the speed at which the corresponding camera function is performed according to the force with which the user tilts the joystick 320. For example, the greater the force with which the joystick 320 is tilted, the faster the zoom or pan operation may be performed.

[0080] Furthermore, in this system 1, the assignment of various camera functions to user operations is not limited to the above and can be freely changed. For example, with respect to the zoom in / out function, in this system 1, contrary to the example above, the zoom in function may be assigned to an operation that narrows the distance between the joysticks 320 in both hands, and the zoom out function may be assigned to an operation that widens that distance.

[0081] 2-3. Setting up function assignments In this system 1, the process of setting the function assignments of the grip devices 3L and 3R on both sides in step S2 of Figure 4A will be explained using Figures 4B to 4C and Figures 7 to 8. Figures 4B and 4C are flowcharts illustrating the function assignment setting process (S2 in Figure 4A) in this system 1.

[0082] 2-3-1. When operating with both hands simultaneously Figure 7(A) illustrates the menu screen for grip settings in the digital camera 10. For example, in step S2 of Figure 4A, the camera control unit 180 first displays a menu screen like that shown in Figure 7(A) on the display monitor 210 (S10).

[0083] In this embodiment, the digital camera 10 allows the user to set separate camera function assignments for shooting and playback by selecting from options such as "shooting settings" or "playback settings," as shown in Figure 7(A). This example describes the case where shooting settings are selected. In this system 1, these separate assignment settings are not limited to shooting and playback; for example, options for still photography or video recording may also be provided.

[0084] The digital camera 10 of this embodiment displays multiple setting items M1 to M3, such as "simultaneous operation with both hands," on the display monitor 210, as shown in Figure 7(A). In the example in Figure 7(A), setting item M1, which determines whether or not to enable the simultaneous operation with both hands function, is set to ON by the user (YES in S11). Accordingly, the other setting items M2 and M3 are set to OFF and are displayed in gray. The grayed-out display indicates that the user cannot change it.

[0085] For example, if the setting item M1 for simultaneous operation with both hands is ON (YES in S11), the camera control unit 180 sets the target to be read from the pre-saved setting information to the setting information for simultaneous operation with both hands (S12). For example, in the example in Figure 7(A), the camera control unit 180 controls setting items M2 and M3 to OFF and grays them out, and sets the source for reading the function assignment setting information to the camera body 11 (the memory card 200 inserted in it).

[0086] With the grip settings menu screen displayed, the camera control unit 180 accepts various user operations via the various operation units 150 and 32 (S13). For example, if the camera control unit 180 accepts a user operation to change setting item M1 (YES in S13), it repeats the processing from step S11 onwards for the changed setting. On the other hand, if the user performs a predetermined operation, such as pressing the SET button 151 instead of changing setting items M1 to M3 (NO in S13), the camera control unit 180 transitions the display monitor 210 to the function assignment setting screen. Figure 7(B) illustrates the function assignment screen transitioned from the state shown in Figure 7(A).

[0087] The camera control unit 180, as illustrated in Figure 7(B), divides the display monitor 210 into items according to the type of user operation based on the combination of directions of the joysticks 320 on both sides, and displays the currently assigned camera function for each item. As the initial display in Figure 7(B), the camera control unit 180 displays the function assignment according to the setting information D1 obtained in advance from, for example, the flash memory 130 or memory card 200.

[0088] Specifically, if there are no changes to the setting items M1 to M3 due to user operation (NO in S13), the camera control unit 180 determines whether or not there is saved setting information in the read source set in step S12, etc. (S14). If there is saved setting information (YES in S14), the camera control unit 180 obtains the function assignment setting information from the read source (S15). On the other hand, if there is no saved setting information (NO in S14), the camera control unit 180 obtains setting information that has been pre-stored as a default in, for example, the flash memory 130, etc. (S16).

[0089] Subsequently, the camera control unit 180 accepts various user operations to modify the function assignments indicated by the acquired setting information (S17). If the function assignments are modified by user operations (YES in S17), the camera control unit 180 reflects the modification results, such as by writing the modified function assignment setting information to a predetermined storage location (S18). On the other hand, if there are no user operations to modify the function assignments (NO in S17), the camera control unit 180 terminates the process shown in Figure 4B and applies the acquired setting information to the function assignments of this system 1 (S4 in Figure 4A).

[0090] In the process of modifying function assignments (S17, S18), System 1 accepts a specification operation on the function assignment screen in which the user specifies the item to which they want to change the assigned camera function, such as "Zoom In" in the example of Figure 7(B). The specification operation is performed, for example, by the touch panel 155, joystick 320, or directional keys 321 and SET button 151.

[0091] Figure 7(C) illustrates the function selection screen that has been transitioned from the state shown in Figure 7(B). The camera control unit 180 displays a list of assignable camera functions for a specified item (user operation), as shown in Figure 7(C), and accepts a selection operation from the user to select the desired camera function from the list. The selection operation is performed, for example, using the touch panel 155, joystick 320, or directional keys 321 and SET button 151.

[0092] The screen transitions in Figures 7(A) to 7(C) can be reversed, for example, by the user performing a back operation. The back operation can be performed, for example, by pressing or touching the back button 154. For example, when a back operation is input on the grip setting screen as shown in Figure 7(A), the camera control unit 180 terminates the process shown in Figure 4B, and as a result of the processing in step S2 of Figure 4A, the setting information D1 corresponding to the function assignment screen immediately preceding the back operation is applied to the function assignment of this system 1 (S4).

[0093] The above description illustrates an example of function assignment for simultaneous two-handed operation of tilting both joysticks 320 in the up, down, left, and right directions. However, the System 1 is not limited to this. For example, the System 1 may also accept camera function assignments for operations of tilting the joysticks 320 in various diagonal directions, similar to the above. For example, 64 different camera functions can be assigned to simultaneous two-handed operation of tilting each joystick 320 in eight different directions. Furthermore, the System 1 may also accept function assignments for operations of pressing the center of the joystick 320.

[0094] Furthermore, in this system 1, the target of simultaneous operation with both hands is not limited to the joystick 320, but may also be various operating members on the operating section 32 of the grip device 3 (or the operating section 150 of the digital camera 10). For example, simultaneous pressing of the function buttons 322 to 324 on both grip devices 3L and 3R, or simultaneous operation of the directional keys 321, may also be assigned camera functions. Moreover, simultaneous operation with both hands in this system 1 is not limited to simultaneous operation of the same type of operating member; simultaneous operation of different types of operating members may also be assigned camera functions.

[0095] 2-3-2. When not operating with both hands simultaneously As described above, with System 1, the user can assign and set desired camera functions for various simultaneous two-handed operations. In System 1, it is possible to assign user-desired camera functions not only to simultaneous two-handed operations but also to individual operations on the grip device 3. An example of this will be explained using Figure 8.

[0096] Figure 8(A) shows a different display example of the grip setting menu screen in the digital camera 10, compared to Figure 7(B). In this example, since the first setting item M1 is OFF, the remaining second and third setting items M2 and M3 are displayed as user-configurable rather than being grayed out. In step S2 (Figure 4A) in this case, the camera control unit 180 assigns camera functions to the individual operations of the various operating members in the grip devices 3R and 3L on both sides, instead of the simultaneous operation of both hands described above.

[0097] In the example in Figure 8(A), the user has set the second setting item M2 to OFF. In this case, the camera control unit 180 sets the function assignments of the grip devices 3R and 3L on both sides independently of each other (see Figures 8(B) and (C)). In the example in Figure 8(A), a list M20 containing the configurable options for this setting item M2 is displayed. For this setting item M2, the user can select, for example, "Right Grip" or "Left Grip" as an alternative to "OFF". "Right Grip" determines the function assignment of the left grip device 3L according to the function assignment setting of the right grip device 3R. "Left Grip" does the opposite, matching the function assignment of the right grip device 3L to the left grip device 3R.

[0098] In this embodiment, the camera system 1 can store data (setting information) indicating the function assignment settings in the digital camera 10 not only in the digital camera 10 but also in the grip device 3 (details will be described later). In the example in Figure 8(A), the third setting item M3 is set to ON, and the setting information stored in the grip device 3 is enabled and used preferentially over the setting information stored in the camera body 11, for example. On the other hand, when this setting item M3 is OFF, the settings stored in the camera body 11 are used preferentially. If no setting information is stored in the grip device 3, this setting item M3 is set to OFF and displayed in gray.

[0099] For example, as shown in Figures 4B and 4C, the camera control unit 180 processes setting items M2 and M3 when the setting item M1 for simultaneous operation with both hands is OFF (NO in S11) (S20-26). For example, if the setting item M2 for "match left and right settings" is "right grip" ((i) in S20), the camera control unit 180 sets the setting information for function assignment related to the operation section 32 of the right grip device 3R as the target for reading in step S15 (S21).

[0100] Furthermore, if setting item M2 is "left grip" (S20 (ii)), the camera control unit 180 sets the setting information for the function assignment of the left grip device 3L as the target for reading (S22). Also, if setting item M2 is "OFF" (S20 (iii)), the camera control unit 180 sets the setting information for the function assignment of both grip devices 3R and 3L as the target for reading (S23).

[0101] Furthermore, if the setting item M3, "Prioritize grip settings," is ON (S24), the camera control unit 180 sets the grip device 3 as the read source in step S15 (S25). On the other hand, if setting item M3 is OFF (NO in S25), the camera control unit 180 sets the camera body 11 as the read source (S26). After that, the camera control unit 180 proceeds to step S13, for example, in Figure 4B.

[0102] Figures 8(B) and 8(C) illustrate the function assignment screens for the right and left grip devices 3R and 3L, respectively, in the example shown in Figure 8(A). For example, when the user performs the same operations as in the examples of Figures 7(A) and 7(B) from the state shown in Figure 8, the display monitor 210 transitions to the state shown in Figure 8(B). The display monitor 210 also transitions between the states shown in Figures 8(B) and 8(C) by operating the DISP button 152.

[0103] In this example, the camera control unit 180 accepts, for example, the operation to specify the camera function to be changed for each operating member on the right-hand grip device 3R while the function assignment screen shown in Figure 8(B) is displayed, in the same manner as in the example in Figure 7(B). Figure 8(D) illustrates the function selection screen that transitions from the state in Figure 8(B) in accordance with the specified operation. Note that the function selection screen that transitions from the state in Figure 8(C) in accordance with the specified operation is the same as in Figure 8(D).

[0104] Furthermore, in this example, the camera control unit 180 accepts, for example, the operation to specify the camera function to be changed for each operating member of the left grip device 3L while the function assignment screen in Figure 8(C) is displayed, in the same manner as in the example in Figure 8(B). If the second setting item M2 in Figure 8(A) is "right grip" or "left grip", only one of the function assignment screens in Figure 8(B) or Figure 8(C) may be displayed, respectively. Alternatively, the other function assignment screen may be displayed grayed out.

[0105] Furthermore, the camera control unit 180 may, for example, perform the initial display of the function assignment screens shown in Figures 8(B) and 8(C) in accordance with the third setting item M3 of the grip setting screen (Figure 8(A)). For example, in the example shown in Figure 8(A), since setting item M3 is ON, the camera functions for each operating member to be initially displayed in Figures 8(B) and 8(C) may be displayed according to the setting information stored in each grip device 3R and 3L.

[0106] According to the operation of the digital camera 10 described above, when grip devices 3R and 3L are attached to both sides of the camera body 11 (YES in S1), simultaneous operation with both hands or other function assignments can be performed as desired, depending on how the user uses the system 1.

[0107] Furthermore, in this system 1, if, for example, only one of the two grip devices 3L, 3R is attached to the camera body 11 (NO in S1 of Figure 4A), the camera control unit 180 sets the "simultaneous operation with both hands" setting item M1 to OFF and displays it in gray. In this case, the camera control unit 180 also sets the "match left and right settings" setting item M1 to OFF and displays it in gray. On the other hand, the "prioritize grip settings" setting item M3 is displayed as user selectable, for example. In this case, depending on the attached grip device 3, camera functions can be assigned in the same manner as above using either the function assignment screen in Figure 8(B) or 8(C).

[0108] In the above explanation, the camera body 11 and grip device 3 were used as examples of sources for reading function assignment setting information. However, the system 1 is not limited to these; for example, the function assignment setting information may be stored on a cloud server and used as a source for reading it.

[0109] 2-4. Saving / Loading Grip Settings System 1 allows you to save the function assignment settings described above and load and use the saved settings. Figure 9 shows an example of the grip setting save / load screen in System 1.

[0110] For example, when a user operates the Q button 153 on a function assignment screen such as Figures 7(B), 8(B), or 8(C), the camera control unit 180 transitions the display monitor 210 to the screen shown in Figure 9. This screen includes selection items such as "Save," "Load," and "Delete."

[0111] When "Save" in Figure 9 is selected by the user, the camera control unit 180 saves the setting information corresponding to the previous function assignment screen, for example. The user can select one of the memory cards 200 in each card slot 190, or one of the attached grip devices 3, as the save location for the setting information. For example, the camera control unit 180 saves the function assignment setting information on the memory card 200, associating it with the contents of setting items M1 and M2 on the grip setting screen, and assigning an appropriate file name. Multiple files of setting information may be stored on the memory card 200, regardless of the model of the digital camera 10.

[0112] Furthermore, when "Load" in Figure 9 is selected by the user, the camera control unit 180 reads the saved function assignment setting information and displays it, for example, on the function assignment screen. As the source for reading the setting information, for example, one of the memory cards 200 for each card slot 190, or one of the attached grip devices 3 can be selected. In addition, presets such as for video recording or still image shooting, or for right-handed or left-handed users may be provided as the setting information to be read.

[0113] By loading this configuration information, users can utilize the saved configuration information by adopting the function assignments or modifying the saved content. The storage location and source of the function assignment configuration information are not limited to the above; for example, external storage devices such as external SSDs or HDDs, or cloud servers may also be selectable.

[0114] Furthermore, when "Delete" in Figure 9 is selected by the user, the camera control unit 180 accepts the user's request to select the setting information they wish to delete and deletes the user-selected setting information from its storage source.

[0115] 2-4-1. Saving setting information in the grip device Figure 10 illustrates the data structure of the setting information stored in the grip device 3 in the camera system 1 of this embodiment.

[0116] In this embodiment, the grip device 3 stores setting data D2 in the storage unit 34, which manages the setting information D2a to D2d for each function assignment for each model A to D of the camera body 11, as shown in Figure 10, for example. For example, the grip control unit 33 identifies the model of the attached camera body 11 through data communication with the camera control unit 180 via the mounting unit 31, and transmits the setting information for the model identified in the setting data D2 to the camera control unit 180 for setting.

[0117] The above settings can be made as needed in response to information received from the camera body 11. Furthermore, if the camera body 11 instructs the grip control unit 33 to save or erase setting information, it will rewrite the setting information for the corresponding model in the setting data D2 in the storage unit 34. The advantages of having the grip device 3 store the setting data D2 in this way will be explained below.

[0118] For example, a model change of the camera body 11 may result in the addition of camera functions in the new model that were not present in the old model, or the removal of functions that were present in the old model. Furthermore, there may be differences in the functions installed on each model depending on the difference between entry-level and high-end models, or between models that prioritize still photography and models that prioritize video. Therefore, the grip device 3 of this embodiment manages the function assignment setting data D2 for each model. This allows the grip device 3 to proactively set the camera function assignment according to the model of the attached camera body 11.

[0119] This embodiment of the grip device 3 is particularly useful in use cases where multiple users share the same digital camera 10 (camera body 11), with each user possessing their own grip device 3. By attaching their own grip device 3 to the shared camera body 11, each user can automatically obtain settings for functions that suit them. Even if there are multiple shared camera bodies 11 or multiple models, users can still obtain the automatic settings described above by using their own grip device 3.

[0120] Furthermore, the grip device 3 of this embodiment is also useful when a single user uses multiple models of digital cameras (camera bodies 11). Even in this case, the user connects their grip device 3 to each camera body 11, and the grip device 3 automatically sets the appropriate function assignments for the connected camera body 11 models. In this way, the system 1 can be made easier for the user to use. Also, even when a single user uses multiple grip devices 3, or when multiple users share multiple digital cameras 10 of multiple models, the system 1 can be made easier to use by using the setting data stored in the grip device 3, similar to the above.

[0121] Furthermore, in the function assignment setting process in this system 1 (S2 or S3 in Figure 4A), by turning ON the setting item M3 "Prioritize grip settings," for example as shown in Figure 8(A), the user can use the setting information D2a to D2d stored in the grip device 3 with the digital camera 10. In addition, the user can also save the setting information D2a to D2d stored in the grip device 3 to a memory card 200, etc., by having the camera body 11 read it (see Figure 9).

[0122] The above description illustrates an example of operation in which the setting information for function assignment in the case of simultaneous operation with both hands is not stored in the grip device 3. However, the System 1 is not limited to this, and the setting information for simultaneous operation with both hands may be stored in the grip device 3. For example, by deciding which of the two grip devices 3R and 3L will be used as the priority setting, the camera control unit 180 may adopt the setting information for simultaneous operation with both hands if it is stored in the preferred grip device 3. In this case, the setting data stored in the grip device 3 may include information on setting items such as simultaneous operation with both hands, in addition to the data structure shown in the example in Figure 10.

[0123] 3. Summary As described above, in this embodiment, the digital camera 10 and the camera body 11 are each an example of an imaging device that accepts user operation at a grip device 3, which is an example of at least one input device. The imaging device comprises a mounting part 2, which is an example of a connection part, and a camera control unit 180, which is an example of a control unit. The mounting part 2 is connected to the grip device 3 to input signals indicating the operation of various operating members of the operating unit 32 provided on the grip device 3. The camera control unit 180 controls the execution of functions that are pre-assigned to the operation of the operating members of the operating unit 150,32, from among a plurality of functions (camera functions) including functions related to image capture by the imaging device, in response to the input signals. The connection part is connected to the grip device 3 in a plurality of embodiments in which the user operates the imaging device using the grip device 3, and the camera control unit 180 changes the assignment of a plurality of functions to the operating members according to the manner in which the grip device 3 is used.

[0124] With the above imaging device, by changing the assignment of camera functions according to various ways in which the user uses the grip device 3, it becomes easier to operate the imaging device using various operating members, including the operating member of the operating section 32 of the grip device 3, in accordance with the user's preferences.

[0125] In this embodiment, the camera control unit 180 detects when the grip device 3 is connected to the connection part (S1). This makes it easier for the user to operate the imaging device using various operating members according to their preferences, depending on the configuration of the connected grip device 3.

[0126] In this embodiment, at least one grip device 3 includes grip devices 3L and 3R as examples of first and second input devices. The connection portion includes a mounting portion 2L as an example of a first mounting portion for attaching the grip device 3L to one side of the imaging device, and a mounting portion 2R as an example of a second mounting portion for attaching the grip device 3R to the other side. This makes it easier to operate the imaging device using various operating members, depending on how the grip device 3 is attached to both sides or one side of the imaging device at each mounting portion 2L and 2R.

[0127] In the imaging device of this embodiment, multiple embodiments include a mode in which the user uses the grip device 3 with both hands and a mode in which the user uses the grip device 3 with one hand. Depending on whether the user uses the device with both hands or one hand, the system 1 can be made to facilitate operation of the imaging device using various operating members.

[0128] The imaging device of this embodiment further includes a display monitor 210 that displays various setting screens and an operation unit 150 that accepts its operation, as an example of a setting unit that assigns multiple functions to multiple operating members, including the operating member of the grip device 3, based on user instructions. This allows the user to specify desired function assignments, making it easier to operate the imaging device using various operating members in accordance with the user's preferences.

[0129] In this embodiment, when the camera control unit 180 receives input for a first user operation, such as simultaneous operation of two joysticks 320 (see Figure 5) (YES in S5 and S6), it executes the first of several functions (S7). On the other hand, if the first user operation is not input to the two operating members, the camera control unit 180 does not execute the first function (NO in S6). This allows the camera function to be executed in response to simultaneous operation by the two operating members, making it easier to operate the imaging device according to the user's preferences.

[0130] In this embodiment, when the camera control unit 180 receives a second user operation in which two operating members are operated simultaneously in a manner different from the first user operation, it executes a second function different from the first function among multiple functions. For example, the two types of simultaneous two-handed operations in Figure 5 are examples of first and second user operations, and the corresponding camera functions are examples of first and second functions. This function assignment for simultaneous two-handed operations makes it easier for the user to use multiple camera functions and operate the imaging device.

[0131] In this embodiment, a camera system 1, which is an example of an imaging system, comprises at least one grip device 3 and imaging devices (10, 11). At least one of the imaging devices (10, 11) and the grip device 3 includes a storage unit that stores setting information indicating the assignment of multiple functions to an operating member. With such a camera system 1, it is possible to easily operate the imaging device with various operating members in accordance with the user's preferences.

[0132] In this system 1, the camera body 11 has a predetermined external shape, such as a box shape. The grip device 3 has a shape more suitable for gripping by the user's hand than the external shape of the camera body 11. With such a grip device 3, a camera system 1 can be provided that is easier for the user to grip than the camera body 11.

[0133] The imaging device of this embodiment includes a connection unit connected to the grip device 3 to input a signal indicating the operation of an operating member provided on the grip device 3, and a camera control unit 180 that controls the execution of a function pre-assigned to the operation of the operating member from among a plurality of functions, including functions related to image acquisition by the imaging device, in response to the input signal. When a first user operation is input, in which two operating members, including the operating member of the grip device 3, are operated simultaneously, the camera control unit 180 executes a first function from among the plurality of functions, and when a second user operation is input, in which the two operating members are operated simultaneously in a manner different from the first user operation, the camera control unit 180 executes a second function from among the plurality of functions, different from the first function. Even with such an imaging device, it is possible to easily operate the imaging device with various operating members in accordance with the user's preferences.

[0134] In this embodiment, the grip device 3 is an example of an input device that accepts user operation for the imaging device. The grip device 3 comprises various operating members in the operation unit 32, an attachment unit 31 which is an example of a connection unit that connects to the imaging device to output signals to the imaging device indicating operation of the operating members, a storage unit 34 which stores setting information indicating the assignment of multiple functions in the imaging device to the operating members, and a grip control unit 33 which is an example of a control unit that sets the setting information to the imaging device via the connection unit. With such an input device, by utilizing the setting information stored in the input device, it is possible to easily operate the imaging device with various operating members in accordance with the user's preferences.

[0135] In the grip device 3 of this embodiment, the storage unit 34 stores setting information D2a to D2d according to the type of imaging device. The grip control unit 33 sets setting information on the imaging device according to the type of imaging device connected to the connection unit. This makes it easier to operate the imaging device using the operating member in accordance with the user's preferences, using setting information of different types, such as the model of the imaging device.

[0136] (Other embodiments) As described above, Embodiment 1 has been explained as an example of the technology disclosed in this application. However, the technology in this disclosure is not limited to this and can be applied to embodiments that have been modified, substituted, added, or omitted as appropriate. Furthermore, it is possible to create new embodiments by combining the components described in the above embodiment. Therefore, other embodiments are described below as examples.

[0137] In the above-described Embodiment 1, a camera system 1 in which a grip device 3 is attached to a digital camera 10 was explained. In this embodiment, the grip device 3 does not need to be attached to the digital camera 10. Such modifications will be explained with reference to Figure 11.

[0138] Figure 11 illustrates a modified camera system 1A. In the camera system 1A of this embodiment, the grip device 3A may remotely control the digital camera 10. In this embodiment, the grip device 3A may, for example, have the same configuration as in Embodiment 1, and as an example of a connection part that replaces the mounting part 31, it may include an interface circuit that communicates with the digital camera 10, etc., by wireless communication (or cable communication).

[0139] In the example shown in Figure 11, the camera system 1A may include a tripod head 15 and a slider 16 to support the digital camera 10, in addition to the digital camera 10 and the grip device 3A. For example, in the digital camera 10 of this embodiment, the camera control unit 180 has the function of controlling the drive of the tripod head 15 and the slider 16. In such a camera system 1A, various functions may be assigned to the operating member of the grip device 3A, for example, to perform pan drive (rotation around the X axis) and tilt drive (rotation around the Y axis) of the tripod head 15, or slide drive of the slider 16. For example, a user can implement a shooting technique in which they operate the pan drive of the tripod head 15 with one joystick 320 of the grip devices 3A in both hands, while operating the slide drive of the slider 16 with the other joystick 320.

[0140] Furthermore, the camera system 1 in this embodiment may have a mode switching function that allows switching between a function assignment for simultaneous operation with both hands and a function assignment that does not, for example, when grip devices 3R and 3L are attached to both sides of the digital camera 10. Such an example will be explained with reference to Figure 12.

[0141] The flow illustrated in Figure 12 starts with, for example, the function assignment mode switching function assigned to a function button 322, and the setting information for the function assignment of each mode saved in the digital camera 10. In this state, when the user operates the function button 322 while using the system 1 (YES in S31), the camera control unit 180 changes the setting information to be applied from the pre-saved setting information (S32). This makes it easier for the user to use the system 1 by switching between the two-handed simultaneous operation mode and the other mode as needed when operating the digital camera 10 with both hands.

[0142] As described above, the imaging device of this embodiment has multiple setting modes in which multiple functions are assigned to the operating members in different ways, and the camera control unit 180 may change the assignment of multiple functions according to the user's selection in the multiple setting modes. This also makes it easier for the user to operate the imaging device using various operating members in accordance with their preferences.

[0143] Furthermore, in this embodiment, the grip device 3 may be provided in various sizes. For example, a small grip device 3 may be easier to use for users with relatively small hands, and the device configuration may be lighter and more compact. Conversely, a large grip device 3 may be easier to use for users with relatively large hands, and the battery 30 may have a larger capacity.

[0144] Furthermore, the above embodiment described simultaneous two-handed operation of two operating members in the grip device 3. In this embodiment, the operating members to be operated simultaneously are not necessarily limited to the operating members of the grip device 3, but may also include the operating section 150 of the digital camera 10. For example, the camera function may be assigned to simultaneous two-handed operation of an operating member provided on the camera body 11 and an operating member of the grip device 3. Moreover, the camera function is not limited to two operating members operated with both hands, but may be assigned to multiple operating members, for example, that are operated with multiple fingers of the same hand.

[0145] Furthermore, in the above embodiment, the grip device 3 was shown as an example of an input device. The input device in this embodiment is not necessarily limited to the grip device 3, but may be any type of input device that accepts user input for operating the imaging device. An example of such a modification will be explained with reference to Figure 13.

[0146] Figure 13 illustrates an example of an input device 3B in a modified configuration. In the imaging system of this embodiment, an input device 1B having a shape suitable for the user to grasp with both hands may be used, for example, as shown in Figure 13. In the imaging device of this embodiment, the various operation units 32 in such a modified input device 3B can also be assigned functions in the same way as in the above embodiment.

[0147] In the above embodiment, an example configuration of a digital camera 10 was described as an example of an imaging device. In this embodiment, the digital camera 10 is not particularly limited to the above configuration and may have various configurations. For example, the digital camera 10 does not have to be interchangeable-lens type, but may have an integrated lens type. Also, the digital camera 10 does not have to be a box camera. The imaging device in this embodiment may be a head-mounted display or smart glasses, etc.
