[0010] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In this embodiment, a focus preset registration operation (FP registration operation) and a focus preset call operation (FP call operation) will be collectively referred to as a focus preset operation (FP operation). Furthermore, a focus preset registration function (FP registration function) and a focus preset call function (FP call function) will be collectively referred to as a focus preset function (FP function).

[0011] <Embodiment 1> [Configuration of camera system 100] 1 is a block diagram showing the configuration of a camera system 100 according to this embodiment. The camera system 100 is, for example, an imaging device such as a digital single-lens reflex camera.

[0012] The camera system 100 is made up of an imaging lens 101 and a camera body 102. The camera body 102 is capable of communicating with the imaging lens 101.

[0013] The imaging lens 101 and the camera body 102 are connected via an I / F (interface) 103, and the imaging lens 101 is an interchangeable lens that can be attached to the camera body 102.

[0014] (Configuration of imaging lens 101) The lens system control unit 110 controls the system of the imaging lens 101 .

[0015] A ROM (Read Only Memory) 128 is a non-volatile memory that stores a control program that can be executed by the lens system control unit 110. It also stores various information, setting values, and the like.

[0016] A RAM (Random Access Memory) 129 is a volatile memory that is used as a work memory when the lens system control unit 110 executes the control program stored in the ROM 128 .

[0017] The imaging lens 101 includes a lens group 113 consisting of multiple lenses, such as a focus lens 114 that adjusts the focus position. The focus lens 114 is held by a lens holding frame (not shown), and the lens holding frame can be driven in the direction of an optical axis 111 by an actuator (not shown).

[0018] The lens operation unit 112 is an operation mechanism for inputting instructions for various operations of the lens system control unit 110, and is configured with one or a combination of buttons, switches, dials, etc. When the lens operation unit 112 is operated, the operation is notified to the lens system control unit 110, and the lens system control unit 110 executes processing according to the notified operation.

[0019] The lens operation unit 112 includes a lens FP registration button for registering a focus position acquired by a focus position detection unit 125 (described later) in the imaging lens 101, and a lens FP call button 903 for recalling a focus position registered in the imaging lens 101. The lens operation unit 112 also includes a focus ring 902 (FIG. 9A). The focus ring 902 allows manual adjustment of the focus position, and the focus position can be moved depending on the amount of movement (rotation) of the focus ring 902. The lens operation unit 112 may also include a playback ring (not shown), to which a lens FP call function may be assigned. If the playback ring is assigned the lens FP registration function, it is also possible to recall a focus position registered in the imaging lens 101 in accordance with the rotation of the playback ring. In this embodiment, the imaging lens 101 will be described as having a lens FP registration button and a lens FP call button. However, a single button may serve as both the lens FP registration button and the lens FP call button. In this case, the imaging lens 101 may be configured to function as either the lens FP registration button or the lens FP call button by using another operation unit such as a switch provided on the imaging lens 101.

[0020] Furthermore, a customization button is included in the lens operation unit 112 of the imaging lens 101. A camera FP calling function for calling a focus position registered in the camera body 102 can be assigned to this customization button.

[0021] The communication unit 115 communicates with the camera body 102 via the I / F 103, receives information such as focus drive instructions and the status of manual focus adjustment processing from the camera body 102, transmits the focus lens drive status to the camera body 102, and communicates various information and instructions.

[0022] The focus driver 118 controls the actuator to move the lens holding frame in the direction of the optical axis 111 , thereby changing the focus position of the focus lens 114 .

[0023] The focus position detection unit 125 detects the current focus position of the focus lens 114 by managing the position of the focus lens 114. The function of the focus position detection unit 125 may be provided to the lens system control unit 110.

[0024] (Configuration of camera body 102) The camera body system control unit 150 controls the system of the camera body 102 .

[0025] The imaging element 154 is a CCD (Charge Coupled Device) sensor, a CMOS (Complementary Metal-Oxide-Semiconductor) sensor, etc. The imaging element 154 photoelectrically converts a subject image formed by an imaging optical system in the interchangeable lens 100 and outputs an electrical signal (analog signal).

[0026] The image processing unit 155 converts the analog signal from the image sensor 154 into a digital signal and performs various image processing to generate image data. From the image data, it generates focus information that indicates the contrast state of the subject image (the focus state of the imaging optical system) and luminance information that indicates the exposure state. The image processing unit 155 outputs the image data to the display unit 153, and the display unit 153 displays the image data as a live view image that can be used to check the composition, focus state, etc.

[0027] The power supply control unit 151 is made up of a battery detection circuit, a DC-DC converter, a switch circuit for switching between blocks to which electricity is applied, etc. The power supply control unit 151 detects whether a battery is connected, the battery type, and the remaining battery power, and controls a DC-DC converter (not shown) based on the detection results and instructions from the camera body system control unit 150 to supply the required voltage to each unit of the camera system 100 for the required period.

[0028] Camera body operation unit 152 is an operation mechanism for inputting instructions for various operations of camera body system control unit 150, and is configured with one or a combination of buttons, switches, dials, touch panels, pointing using line of sight detection, etc. When camera body operation unit 152 is operated, the operation is notified to camera body system control unit 150, and camera body system control unit 150 executes processing according to the notified operation.

[0029] The camera body operation unit 152 includes, for example, the shutter button 61, the multi-function button 71, the illumination button 80, the video recording button 81, the AF-ON button 82, the AE lock button 83, the AF frame selection button 84, and the SET button 85. Among these, the following functions can be assigned by user settings as functions executed by pressing the multi-function button 71, the illumination button 80, the video recording button 81, the AF-ON button 82, the AE lock button 83, or the AF frame selection button 84: a camera FP registration function for registering a focus position on the camera body 102, and a camera FP recall function for recalling a focus position registered on the camera body 102. In this way, buttons assigned with the camera FP registration function for registering a focus position on the camera body 102 are collectively referred to as camera FP registration buttons. Furthermore, buttons assigned with the camera FP recall function for recalling a focus position registered on the camera body 102 are collectively referred to as camera FP recall buttons.

[0030] The display unit 153 displays a setting screen for making various settings such as exposure parameters and step settings that can be set in each of the above-mentioned functional shooting modes. The user can make various settings by operating the camera body operation unit 152 while looking at the setting screen displayed on the display unit 153. The display unit 153 can also display image data that has been captured by the image sensor 154 and processed by the image processing unit 155 as a live view image.

[0031] The communication unit 165 communicates with the imaging lens 101 via the I / F 103 and can transmit information such as focus drive instructions and a status indicating whether manual focus adjustment processing is possible to the imaging lens 101. It can also receive the focus lens drive status from the imaging lens 101 and communicate various information and instructions.

[0032] The photometry processing unit 156 performs exposure processing using light incident from the imaging lens 101, and sets exposure parameters (aperture value, shutter speed, ISO value).

[0033] The distance measurement processing unit 157 performs a focusing process using light rays incident from the imaging lens 101 when the shutter button 61 is pressed.

[0034] ROM (Read Only Memory) 162 is a non-volatile memory that stores control programs that can be executed by the camera body system control unit 150.

[0035] The RAM (Random Access Memory) 163 is a volatile memory that is used as a work memory when the camera body system control unit 150 executes the control program stored in the ROM 162 .

[0036] The recording medium 164 records images captured by the camera system 100 .

[0037] (Appearance of camera body 102) Fig. 2 is an external view of the camera body 102 according to this embodiment. Fig. 2(a) is a view showing the external shape of the camera body 102 from the front, and Fig. 2(b) is a view showing the external shape of the camera body 102 from the back.

[0038] Display unit 28 is a display unit provided on the rear surface of camera body 102, and displays images and various information. Touch panel 70a can detect touch operations on the display surface (touch operation surface) of display unit 28.

[0039] The shutter button 61 is an operating member for issuing instructions to prepare for photography and instructions to take a photograph. By pressing the shutter button 61 halfway, the brightness of the subject is measured and the camera is focused. By pressing the shutter button 61 all the way, the shutter is released and an image is taken.

[0040] The multifunction button 71 is a push button.

[0041] The illumination button 80 is a push button that can switch on / off illumination such as an LED that makes the operation unit visible even in dark places and illumination of the display unit outside the viewfinder.

[0042] The video recording button 81 is used to instruct the start and stop of video recording (recording).

[0043] The AF-ON button 82 is a push button, and pressing it commands the execution of AF.

[0044] The AE lock button 83 is a push button, and by pressing the AE lock button 83 in the shooting standby state, the exposure state can be fixed.

[0045] The AF frame selection button 84 is a push button, and an AF position (frame) for focusing can be selected by operating a cross key (not shown) or the like.

[0046] The SET button 85 is a push button and is mainly used to confirm a selected item.

[0047] The buttons to which the camera FP call function can be assigned are the multi-function button 71, the illumination button 80, the video recording button 81, the AF-ON button 82, the AE lock button 83, and the AF frame selection button 84. The camera FP call function can also be assigned to a button 86 on the front of the camera. 904 in Figure 9 corresponds to the AF-ON button 82.

[0048] It should be noted that the camera FP registration function can be assigned to button 87 on the front of the camera.

[0049] The following processes shown in Figures 3 to 7 are executed in camera system 100. These processes are executed when camera body 102 is in shooting mode, and during shooting mode, the processes shown in Figures 3 to 7 are executed in parallel.

[0050] [FP registration process] FIG. 3 is a flowchart showing the FP registration process according to this embodiment.

[0051] (Lens FP registration process) Fig. 3(a) is a flowchart showing the lens FP registration process for registering a focus position in the imaging lens 101. The process in Fig. 3(a) is realized by loading a control program recorded in the ROM 128 into the RAM 129, and having the lens system control unit 110 control each unit of the imaging lens 101, execute arithmetic processing, etc. based on the control program.

[0052] In S3001, the lens system control unit 110 determines whether or not the lens FP registration button included in the lens operation unit 112 of the imaging lens 101 has been pressed. If it is determined that the lens FP registration button included in the lens operation unit 112 of the imaging lens 101 has been pressed, the process proceeds to S3002; otherwise, the process proceeds to S3001.

[0053] In S3002, the focus position detection unit 125 of the imaging lens 101 detects the current focus position of the focus lens 114 and notifies the lens system control unit 110 of the detected focus position.

[0054] In S3003, the lens system control unit 110 registers (records) the focus position detected in S3002 in a predetermined storage area (ROM 128, RAM 129, etc.) of the imaging lens 101. The processes of S3002 and S3003 are executed every time the lens FP registration button is pressed.

[0055] (Camera FP registration process) Fig. 3(b) is a flowchart showing the camera FP registration process for registering a focus position in the camera body 102. The process in Fig. 3(b) is realized by loading a control program recorded in ROM 162 into RAM 163, and having the camera body system control unit 150 control each unit of the camera body 102, execute calculation processing, etc. based on the control program.

[0056] In S3004, the camera body system control unit 150 determines whether the camera FP registration button assigned with the camera FP registration function has been pressed on the camera body 102. If it is determined that the camera FP registration button has been pressed, the process proceeds to S3005; otherwise, the process proceeds to S3004.

[0057] In S3005, the camera body system control unit 150 acquires the current focus position of the focus lens 114 detected by the focus position detection unit 125 of the imaging lens 101 by communicating with the imaging lens 101 via the communication unit 115 of the imaging lens 101. Note that if the current focus position of the focus lens 114 has already been acquired and is held in the camera body 102, the focus position held in the camera body 102 may be acquired.

[0058] In S3006, the camera body system control unit 150 registers the acquired current focus position in a predetermined storage area (ROM 162, RAM 163, recording medium 164, etc.) of the camera body 102, and returns to S3004. The processes of S3005 and S3006 are executed each time the camera FP registration button is pressed.

[0059] As described above, in the FP registration process, the current focus position at the time of the registration process is registered (recorded) in a predetermined storage area on the lens side or the camera body side. In this embodiment, the focus position is registered in a predetermined storage area on the lens side or the camera body side, but if the camera system 100 is connected to external storage via a network, the detected focus position may also be registered in the external storage.

[0060] In this way, in this embodiment, the predetermined storage area for registration is divided according to the content of the function executed by the FP operation. Note that, if the focus positions can be registered separately for the imaging lens 101 and the camera body 102, the same storage area may be used regardless of the content of the function executed by the FP operation.

[0061] [FP call processing] (FP call processing on the imaging lens 101 side) Fig. 4 is a flowchart showing FP call processing on the imaging lens 101 side according to this embodiment. The processing in Fig. 4 is realized by loading a control program recorded in ROM 128 into RAM 129, and having the lens system control unit 110 control each unit of the imaging lens 101, execute arithmetic processing, etc. based on the control program.

[0062] In S4001, the lens system control unit 110 determines whether pressing of the lens FP call button of the lens operation unit 112 has started, that is, whether the lens FP call button has switched from a not-pressed state to a pressed state. If it is determined that pressing of the lens FP call button has started, the process proceeds to S4002; otherwise, the process proceeds to S4008. Note that if the FP call function is assigned to playback ring operation, in S4001, it may be determined not only whether pressing of the lens FP call button has started, but also whether the playback ring has been operated.

[0063] In S4002, the lens system control unit 110 acquires the focus position registered in a predetermined storage area (ROM 128, RAM 129) of the imaging lens 101 in S3003.

[0064] In S4003, the lens system control unit 110 sets the focus position acquired in S4002 as the target focus position in the focus driving unit 118, and the focus driving unit 118 starts driving the focus lens 114. Specifically, the focus driving unit 118 starts moving the focus lens 114 from the focus position at the time when pressing of the lens FP call button started to the target focus position.

[0065] In S4004, the lens system control unit 110 sets the lens FP call driving state. That is, the lens system control unit 110 stores, in the RAM 129, information indicating that the focus lens is currently being driven by the lens FP call process as the current state of the imaging lens 101.

[0066] In S4005, the focus driver 118 determines whether or not the focus lens 114 has reached the target focus position. If it is determined that the focus lens 114 has reached the target focus position, the process proceeds to S4006; otherwise, the process proceeds to S4005.

[0067] In S4006, the focus driver 118 stops driving (moving) the focus lens 114.

[0068] In S4007, in response to the focus lens movement by the focus driver 118 being stopped in S4006, the lens system controller 110 cancels the setting of the lens FP call driving state. That is, the lens system controller 110 deletes the information indicating that the lens is being driven by the FP call process, which was stored in the RAM 129 in S4004. Then, the process returns to S4001.

[0069] In S4008, the lens system control unit 110 determines whether or not the communication unit 115 has received a focus drive instruction from the camera body 102. This focus drive instruction corresponds to the focus drive instruction sent from the camera body to the imaging lens in S5003, which will be described later, and the focus drive instruction includes information about the target focus position.

[0070] In S4009, the lens system control unit 110 sets the target focus position included in the focus drive instruction received in S4008 in the focus drive unit 118, and the focus drive unit 118 starts focus drive to the set target focus position. Specifically, the focus drive unit 118 starts moving the focus lens 114 from the current focus position to the target focus position.

[0071] In S4010, the lens system control unit 110 sets the focus lens drive state to moving.

[0072] In S4011, the lens system control unit 110 determines whether the communication unit 115 has received a focus lens drive state request from the camera body 102. This focus lens drive state request corresponds to the focus lens drive state request transmitted from the camera body 102 in S5004, which will be described later. If it is determined that a focus lens drive state request has been received from the camera body 102, the process proceeds to S4012; otherwise, the process proceeds to S4013.

[0073] In S4012, the lens system control unit 110 transmits information indicating that the focus lens drive state is moving (lens drive state information) to the camera body 102 via the communication unit 115 in response to the focus lens drive state request received in S4011.

[0074] In S4013, the lens system control unit 110 determines whether the focus lens 114 has reached the target focus position or whether an instruction to interrupt (stop) focus drive has been issued. If it is determined that the focus lens has reached the target focus position or that an instruction to interrupt focus drive (focus drive stop instruction) has been issued, the process proceeds to S4014; otherwise, the process proceeds to S4011. Note that this focus drive interrupt (stop) instruction corresponds to an instruction issued by focus drive stop processing in S7005, which will be described later.

[0075] In S4014, the focus driver 118 stops driving (movement of the focus position) the focus lens 114. In this way, the focus drive stop process is executed in S7005, and the focus drive stop is instructed, so that the camera FP call process is interrupted in S4014.

[0076] In S4015, the lens system control unit 110 sets the focus lens driving state to stopped.

[0077] In S4016, the lens system control unit 110 determines whether the communication unit 115 has received a focus lens drive state request from the camera body 102. If it is determined that a focus lens drive state request has been received from the camera body 102, the process proceeds to S4017; otherwise, the process proceeds to S4016. This focus lens drive state request corresponds to the focus lens drive state request sent from the camera body 102 in S5004, which will be described later.

[0078] In S4017, the communication unit 115 of the lens system control unit 110 transmits information indicating that the focus lens drive state is stopped to the camera body 102 as a response to the focus lens drive state request received in S4016. Then, the process returns to S4001.

[0079] (FP call processing on the camera body 102 side) Fig. 5 is a flowchart showing FP call processing on the camera body 102 side according to embodiment 1. The processing in Fig. 5 is realized by loading a control program recorded in ROM 162 into RAM 163, and having the camera body system control unit 150 control each unit of the camera body 102, execute arithmetic processing, and the like based on the control program.

[0080] In S5001, camera body system control unit 150 determines whether or not pressing of the camera FP call button of camera body operation unit 152 has started, that is, whether the camera FP call button has switched from a not-pressed state to a pressed state. If it is determined that pressing of the camera FP call button has started, proceed to S5002; otherwise, proceed to S5003.

[0081] In S5002, the camera body system control unit 150 acquires the focus position registered in a predetermined storage area (ROM 162, RAM 163, recording medium 164, etc.) of the camera body 102 in S3006.

[0082] In S5003, the camera body system control unit 150 transmits a focus drive instruction to the imaging lens 101 via the communication unit 165. The transmitted focus drive instruction includes information specifying that the focus position acquired in S5002 is the target focus position.

[0083] In S5004, the camera body system control unit 150 causes the communication unit 154 to send a focus lens drive state request to the imaging lens 101.

[0084] In S5005, the camera body system control unit 150 receives focus lens drive state information sent from the imaging lens 101 by the processing of S4012 or SS4017 of the imaging lens 101. That is, in S5005, the camera body system control unit 150 receives focus lens drive state information as a response to the focus lens drive state request sent to the imaging lens 101 in S5004. The camera body system control unit 150 then determines whether the received focus lens drive state is moving or stopped. If it is determined that the focus lens drive state is stopped, the process proceeds to S5006, and if it is determined that the focus lens drive state is moving, the process proceeds to S5007.

[0085] In S5006, the camera body system control unit 150 stores in the camera body 102 that the focus lens drive state is stopped. Specifically, the camera body system control unit 150 stores information indicating that the focus lens drive state is stopped in an area in RAM 163 for storing the drive state of the focus lens. Then, the process proceeds to S5008.

[0086] In S5007, the camera body system control unit 150 stores in the camera body 102 that the focus lens drive state is moving. Specifically, the camera body system control unit 150 stores information indicating that the focus lens is stopped in an area in RAM 163 for storing the drive state of the focus lens. Then, the process proceeds to S5004. In other words, if the focus lens is moving, the processes of S5004 to S5007 are repeatedly executed.

[0087] In S5008, the camera body system control unit 150 determines whether the pressing of the camera FP call button started in S5001 is still ongoing. If it is determined that the pressing of the camera FP call button is still ongoing, the process proceeds to S5010; otherwise, the process proceeds to S5009.

[0088] In S5010, the camera body system control unit 150 stores information indicating that the state of the camera FP call button is in a pressed state in RAM 163, thereby setting the state as the camera FP call button is in a pressed state, and proceeds to S5008.

[0089] In S5009, the camera body system control unit 150 erases from RAM 163 the information indicating that the camera FP call button is in a pressed state, cancels the camera FP call button pressed state set in S5010, and proceeds to S5001.

[0090] [Setting whether manual focus adjustment processing is possible by manual focus adjustment operation according to the camera settings] Fig. 6 is a flowchart related to setting the availability of manual focus adjustment processing by manual focus adjustment operation according to the camera settings. Here, the manual focus adjustment operation refers to operation of focus ring 902. Setting the availability of manual focus adjustment processing by manual focus adjustment operation is a setting for switching whether or not to execute processing for driving focus lens 114 according to the amount of operation (amount of rotation) when focus ring 902 is operated (rotated). Fig. 10 is an example of a setting screen related to manual focus adjustment operation.

[0091] (Manual focus adjustment settings) Settings related to manual focus adjustment operation that can be set on camera body 102 will be described with reference to Fig. 10. The setting screen related to manual focus adjustment operation in Fig. 10 is part of the menu screen of camera body 102, and is displayed on display unit 153. Then, in accordance with a user operation on camera body operation unit 152, one of settings 1001 to 1003 can be selected and set on camera body 102.

[0092] Reference numeral 1001 denotes a setting item (mode 3) that always disables the acceptance of manual focus adjustment operations when the camera FP call button is ON, regardless of the focus lens drive state.

[0093] Reference numeral 1002 denotes a setting item (mode 1) that disables the acceptance of manual focus adjustment operations when the focus lens is in a moving state, and enables the acceptance of manual focus adjustment operations when the focus lens is not in a moving state.

[0094] Reference numeral 1003 denotes a setting item (mode 2) that always allows manual focus adjustment operation to be accepted, regardless of the focus lens driving state or the ON / OFF state of the camera FP call button.

[0095] Reference numeral 1004 denotes an OK button. When the user presses the OK button 1004, the setting contents relating to the manual focus adjustment operation are updated to the contents of the selected setting item (enclosed in a bold frame), and the setting screen is exited.

[0096] Reference numeral 1005 denotes a cancel button, and when the user presses the cancel button 1005, the setting contents relating to the manual focus adjustment operation are not updated and the setting screen is exited.

[0097] 10, a setting item 1002 that disables the acceptance of manual focus adjustment operations only during movement to the target focus position is surrounded by a thick frame. When the OK button 1004 is pressed in this state, the setting is changed to disable the acceptance of manual focus adjustment operations only during movement to the target focus position, and the screen exits this setting screen.

[0098] (Setting process for manual focus adjustment process availability on the camera body 102 side) The processing of Figure 6(a) is realized by expanding a control program recorded in ROM 162 to RAM 163, and having the camera body system control unit 150 control each part of the camera body 102, perform calculation processing, etc. based on the control program.

[0099] In S6001, the camera body system control unit 150 determines what setting is set for the manual focus adjustment operation on the setting screen of Fig. 10. If it is determined that the setting for the manual focus adjustment operation is mode 1 (1002), the process proceeds to S6002; if it is determined that the setting is mode 2 (1003), the process proceeds to S6003; and if it is determined that the setting is mode 3 (1001), the process proceeds to S6006.

[0100] In S6002, the camera body system control unit 150 reads the focus lens drive state from RAM 163 and determines whether the focus lens drive state is moving or stopped. This focus lens drive state is information stored in RAM 163 by the processes of S5004 to S5007. If it is determined that the focus lens drive state is moving, the process proceeds to S6004, and if it is determined that the focus lens drive state is stopped, the process proceeds to S6003.

[0101] In S6003, the camera body system control unit 150 sets the manual focus adjustment processing availability state to possible, so that the communication unit 165 transmits information (availability information) indicating that the manual focus adjustment processing availability state is possible to the imaging lens 101.

[0102] In S6004, the camera body system control unit 150 sets the manual focus adjustment processing availability state to unavailable, so that the communication unit 165 transmits information (availability information) indicating that the manual focus adjustment processing availability state is unavailable to the imaging lens 101.

[0103] In S6005, the camera body system control unit 150 determines whether or not the camera settings related to the manual focus adjustment operation have been changed, or whether or not there has been a change in the focus lens drive state acquired from the imaging lens 101 and stored in the RAM 163. If it is determined that the camera settings related to the manual focus adjustment operation have been changed or that there has been a change in the focus lens drive state, the process returns to S6001 and this flow is repeated.

[0104] In S6006, the camera body system control unit 150 determines whether the focus lens drive state is moving (first condition) or whether the camera FP call button is set to a pressed state (second condition). If it is determined that the focus lens drive state is moving or set to a pressed state, the process proceeds to S6004. Otherwise, if it is determined that the focus lens drive state is stopped and the camera FP call button is not pressed, the process proceeds to S6003.

[0105] In S6003 or S6004, after the information on the availability of manual focus adjustment processing is transmitted to the imaging lens 101, the camera settings may be changed or the focus lens drive state may change. Even in this case, if there is no change in the availability of manual focus adjustment processing, it is not necessary to transmit the information on the availability of manual focus adjustment processing to the imaging lens 101.

[0106] In this way, this processing sets the manual focus adjustment processing availability state in the camera body 102 according to the settings related to the manual focus adjustment operation, the focus lens drive state, and the state of the camera FP call button being pressed. Then, information on the manual focus adjustment processing availability state is transmitted to the imaging lens 101.

[0107] (Setting process for manual focus adjustment process availability on the imaging lens 101 side) The processing in FIG. 6(b) is realized by loading a control program recorded in ROM 128 into RAM 129, and having the lens system control unit 110 control each part of the imaging lens 101, perform calculation processing, etc. based on the control program.

[0108] In S6007, the lens system control unit 110 determines whether or not information indicating that the manual focus adjustment process availability state is unavailable has been transmitted from the camera body 102 as a result of the processing in S6004, and whether or not that information has been received by the communication unit 115. If it is determined that information indicating that the manual focus adjustment process availability state is unavailable has been received, the process proceeds to S6008; otherwise, the process proceeds to S6009.

[0109] In S6008, the lens system control unit 110 sets the manual focus adjustment process availability state to unavailable.

[0110] In S6009, the lens system control unit 110 determines whether or not information indicating that the manual focus adjustment process availability status is available has been transmitted from the camera body 102 by the processing of S6003, and whether or not the communication unit 115 has received that information. If it is determined that information indicating that the manual focus adjustment process availability status is available has been received, the process proceeds to S6010; otherwise, the process proceeds to S6007.

[0111] In S6010, the lens system control unit 110 sets the manual focus adjustment process availability state to available.

[0112] [Manual focus adjustment process] 7 is realized by loading a control program recorded in the ROM 128 into the RAM 129, and the lens system control unit 110 controlling each part of the imaging lens 101 and executing arithmetic processing, etc. based on the control program.

[0113] In S7001, the lens system control unit 110 determines whether or not the focus ring 902 has been operated. If it determines that the focus ring 902 has been operated, the process proceeds to S7002; otherwise, the process returns to S7001.

[0114] In S7002, the lens system control unit 110 determines whether the lens FP call drive is in progress based on the information on the state of the imaging lens 101 that was stored in or deleted from the RAM 129 in S4004 and S4007. If it is determined that the lens FP call drive is in progress, the process returns to S7001. In other words, if the lens FP call drive is in progress, focus adjustment processing is not executed even if the focus ring 902 is operated. If it is determined that the lens FP call drive is not in progress, the process proceeds to S7003.

[0115] In S7003, the lens system control unit 110 determines the setting of the manual focus adjustment process availability state set by the processes of S6007 to S6010. If the manual focus adjustment process availability state is set to available, the process proceeds to S7004. If the manual focus adjustment process availability state is set to unavailable, the process returns to S7001. In other words, if the manual focus adjustment process availability state is set to unavailable, the focus adjustment process is not executed even if the focus ring 902 is operated.

[0116] In S7004, the lens system control unit 110 determines the focus lens drive state set by the processing of S4010 or S4015. If the focus lens drive state setting is moving, proceed to S7005, and if it is stopped, proceed to S7006.

[0117] In S7005, the lens system control unit 110 instructs the focus drive unit 118 to stop focus drive. By instructing the focus drive unit 118 to stop in S7005, the camera FP call process being executed by operating the camera FP call button is interrupted in S4014.

[0118] In S7006, the lens system control unit 110 executes focus adjustment processing (manual focus adjustment processing) according to the operation of the focus ring 902 determined in S7001. Specifically, the lens system control unit 110 detects the operation amount (rotation amount) of the focus ring 902, and causes the focus drive unit 118 to drive (move) the focus lens 114 by an amount corresponding to the operation amount. In other words, the focus lens 114 is moved to a focus position according to the operation of the focus ring 902 and the current focus position.

[0119] As described above, in this process, in the lens FP driving state where FP call processing is being performed in response to operation of the lens FP call button, manual focus adjustment processing is not performed even if the focus ring 902 is operated, regardless of the setting of the manual focus adjustment processing availability state. In other words, in the lens FP driving state, manual focus adjustment processing is not performed even if the focus ring 902 is operated, regardless of the setting related to the manual focus adjustment operation. On the other hand, when the lens FP call driving state is not in progress, that is, when FP call processing is being performed in response to operation of the camera FP call button, the process is different from the lens FP call driving state. In other words, whether or not to perform manual focus adjustment processing in response to operation of the focus ring 902 is switched depending on the setting related to the manual focus adjustment processing availability state. In other words, whether or not to perform manual focus adjustment processing in response to operation of the focus ring 902 is switched depending on the setting related to the manual focus adjustment operation, the camera FP call operation, and the focus lens driving state.

[0120] [Relationship between camera FP call operation, focus lens drive status, and manual focus adjustment processing availability status] 8 is a timing chart showing the relationship between the camera FP call operation, the focus lens drive state, and the availability of manual focus adjustment processing. The switching of the availability of manual focus adjustment processing according to the setting (mode) related to the manual focus adjustment operation will be described with reference to FIG.

[0121] Time passages 801 and 821 in Fig. 8 are arrows that represent the passage of time. The further to the right the arrows point, the more time has passed. T2 is later than T1, and T3 is later than T2. ​​Furthermore, T32 is later than T31, and T33 is later than T32.

[0122] 8 indicate ON / OFF of the camera FP call button operation. While the camera FP call button is being operated, that is, while the camera FP call button is being pressed, it is ON. On the other hand, when the camera FP call button is not being operated, that is, when the camera FP call button is not being pressed, it is OFF.

[0123] 8 indicate the focus lens drive states. "Normal (stopped)" indicates a state in which the camera FP call button is not operated, and indicates that the focus lens drive state is stopped.

[0124] 8 indicates a case where the user has set it to mode 1. A manual focus adjustment process availability status 805 indicates a case where the user has set it to mode 2. A manual focus adjustment process availability status 806 indicates a case where the user has set it to mode 3. The manual focus adjustment process availability status is set to either available or unavailable.

[0125] 8, 811 (time T1) and 831 (time T31) indicate the times when the camera FP call button operation is switched from OFF to ON. 812 (time T2) and 833 (time T33) indicate the times when the current focus position is reached at the target focus position. 813 (time T3) and 832 (time T32) indicate the times when the camera FP call button operation is switched from ON to OFF.

[0126] Figure 8(a) is a timing chart showing a case where, when the FP call process is executed in response to the operation of the camera FP call button, the operation of the camera FP call button continues even after the target focus position is reached, and then the button operation is released.

[0127] At T1, when the operation 802 of the camera FP call button switches from OFF to ON, a Yes is determined in S5001. Then, the processes of S5002, S5003, S4008, and S4009 are executed, and the focus driver 118 starts moving the focus lens 114. Then, the process of S4010 changes the focus lens drive status 803 to "moving."

[0128] At T2, when the focus lens 114 reaches the target focus position (Yes in S4013), the focus drive is stopped by the processes of S4014 and S4015, and the focus lens drive status 803 becomes "stopped."

[0129] The manual focus adjustment process availability state 804 is the case where mode 1 has been set by the user. In mode 1, the processes of S6002 to S6004 and S6007 to S6010 set the focus lens drive state 803 to "available" from T2 onwards, up to T1, during which the focus lens drive state 803 is "stopped". On the other hand, the focus lens drive state 803 is set to "unavailable" from T1 to T2, during which the focus lens drive state 803 is "moving". In mode 1, once the target focus position is reached, manual focus adjustment can be performed even if the camera FP call button remains ON. This allows the user to fine-tune the focus position for shooting by manually operating the focus ring, based on the target focus position.

[0130] The manual focus adjustment process availability state 805 is set to mode 2 by the user. In mode 2, the processes of S6003 and S6010 are executed in the flow of FIG. 6 regardless of the focus lens drive state or the operation state of the camera FP call button. Therefore, whether the focus lens drive state is "moving" or "stopped," the manual focus adjustment process availability state 805 is set to "available." When the camera FP call button is operated and movement to the target focus position is initiated by the FP call process, there may be cases where the user wants to photograph a different subject before reaching the target focus position. In such a case, the movement to the target focus position is interrupted by the processes of S7005 and S4014, and manual focus adjustment can be performed by operating the focus ring 902 by the user. This allows the user to quickly focus on a different subject.

[0131] The manual focus adjustment process availability status 806 is the case where mode 3 has been set by the user. In mode 3, if it is determined in S6006 that the camera FP call button is being pressed, the processes of S6004 and S6008 are executed. Therefore, during T1 to T3, when the camera FP call button is being pressed, the manual focus adjustment process availability status 806 is "unavailable." In FIG. 8A, during the period up to T1 when the camera FP call button is not being pressed and during the period from T3 onward, the focus lens drive state is "stopped." Therefore, the processes of S6003 and S6010 are executed, and the manual focus adjustment process availability status 806 is "available." As a result, while the user is operating the camera FP call button, it is possible to maintain the target focus position not only until the target focus position is reached by the FP call process, but also after the target focus position has been reached. Therefore, it is possible to reliably capture images at the target focus position.

[0132] Next, Fig. 8(b) will be described. Fig. 8(b) is a timing chart showing a case where, when FP call processing is executed in response to the operation of the camera FP call button, the operation of the camera FP call button is released before the target focus position is reached.

[0133] At T31, when the operation 822 of the camera FP call button switches from OFF to ON, a Yes is determined in S5001. Then, the processes of S5002, S5003, S4008, and S4009 are executed, and the focus driver 118 starts moving the focus lens 114. Then, the process of S4010 changes the focus lens drive status 823 to "moving."

[0134] At T32, before the focus lens 114 reaches the target focus position, the operation 822 of the camera FP call button switches from ON to OFF. At T32, the focus lens 114 has not reached the target focus position (No in S4013), so the focus lens drive status 823 remains "moving" due to the processing of S4010.

[0135] At T33, when the focus lens 114 reaches the target focus position (Yes in S4013), the focus drive is stopped by the processes of S4014 and S4015, and the focus lens drive status 823 becomes "stopped."

[0136] The manual focus adjustment process availability state 824 is the case where mode 1 has been set by the user. In mode 1, the processes of S6002 to S6004 and S6007 to S6010 set the focus lens drive state 823 to "available" from T33 onwards, up to T31, when the focus lens drive state 823 is "stopped". On the other hand, the focus lens drive state 823 is set to "unavailable" from T31 to T33, when the focus lens drive state 823 is "moving". In mode 1, manual focus adjustment is made possible once the target focus position is reached. This allows the user to manually operate the focus ring to fine-tune the focus position for shooting, based on the target focus position.

[0137] The manual focus adjustment process availability status 825 is set to mode 2 by the user. In mode 2, the processes of S6003 and S6010 are executed in the flow of FIG. 6 regardless of the focus lens drive state or the operation state of the camera FP call button. Therefore, whether the focus lens drive state is "moving" or "stopped," the manual focus adjustment process availability status 825 is set to "available." When the camera FP call button is operated and movement to the target focus position is initiated by the FP call process, there may be cases where the user wants to photograph a different subject before reaching the target focus position. In such a case, the movement to the target focus position is interrupted by the processes of S7005 and S4014, and manual focus adjustment can be performed by operating the focus ring 902 by the user. This allows the user to quickly focus on a different subject.

[0138] The manual focus adjustment process availability status 826 is the case where mode 3 has been set by the user. In mode 3, if it is determined in S6006 that the camera FP call button is being pressed, the processes of S6004 and S6008 are executed. Therefore, the manual focus adjustment process availability status 826 is "unavailable" during the period from T31 to T32, when the camera FP call button is being pressed. In FIG. 8B, the periods when the camera FP call button is not being pressed are the period up to T31 and the period after T32. Therefore, the processes of S6003 and S6010 are executed, and the manual focus adjustment process availability status 826 is "available." This makes it possible to maintain the target focus position while the user is operating the camera FP call button. On the other hand, if the user is operating the camera FP call button, it becomes possible to perform manual focus adjustment by operating the focus ring or the like, even if the target focus position has not been reached. This allows for focusing on another subject.

[0139] In this way, in the camera system of this embodiment, when FP call processing is performed by operating the camera FP call button, the timing at which manual focus adjustment processing becomes possible is changed according to the settings related to manual focus adjustment operation of the camera body 102. Therefore, it is possible to prevent erroneous operations, and also to quickly perform focus adjustment processing in accordance with the shooting conditions and the user's intentions, so that the timing for shooting is not missed.

[0140] [About misoperation of the focus ring] The possibility of an unintentional erroneous operation of the focus ring 902 by the user will be described with reference to FIG.

[0141] Fig. 9 is a diagram illustrating a possible case where the user may erroneously operate the focus ring 902 while performing an FP call operation. Fig. 9(b) is a diagram showing the user in Fig. 9(a) viewed from the opposite side. In Fig. 9(b), the focus ring 902 is hidden by the user's hand, and is therefore shown with a dotted line.

[0142] The imaging lens 101 is equipped with a focus ring 902. Therefore, the lens FP call button arranged on the same imaging lens 101 is closer to the focus ring than the camera FP call button arranged on the camera body 102.

[0143] Furthermore, rotation of the focus ring 902 applies a force toward the optical axis of the imaging lens 101 (in a direction perpendicular to the optical axis direction of the imaging lens 101). Similarly, pressing the lens FP call button disposed on the imaging lens 101 also applies a force toward the optical axis of the imaging lens 101 (in a direction perpendicular to the optical axis direction of the imaging lens 101). In other words, the direction in which the lens FP call button is pressed is in a position that interferes with the direction in which the focus ring 902 is rotated.

[0144] Therefore, it is believed that preventing manual focus adjustment processing from being executed when the focus lens is in a moving state will help prevent erroneous operations by the user.

[0145] On the other hand, the camera FP call function is assigned to various buttons on the camera body 102. Therefore, depending on the arrangement position of the camera FP call button on the camera body 102, the direction of pressing the camera FP call button may or may not be in a position that interferes with the direction of rotation of the focus ring 902. For this reason, whether or not to execute the focus lens adjustment process can be switched based on the user's settings (modes 1 to 3).

[0146] [Modification of the first embodiment] The settings relating to the manual focus adjustment operation may be set separately for still image shooting and video shooting. Different modes may be used depending on the degree of influence on shooting.

[0147] For example, in the case of still image shooting, the camera FP call button is often operated before shooting, and even if the user unintentionally interrupts movement to the target focus position, still image shooting can be resumed by operating the camera FP call button again. However, in the case of video shooting, the camera FP call button may be operated during shooting, and if the user unintentionally interrupts movement to the target focus position, video shooting must be restarted. Therefore, modes 1, 2, and 3 may be used depending on whether still image shooting or video shooting is being performed.

[0148] <Embodiment 2> The lens operation unit 112 of the imaging lens 101 includes a customization button. This customization button can be assigned an FP call function that calls up a focus position registered in the camera body 102. A case where this customization button is used to call up a focus position registered in the camera body 102 will be described as the second embodiment. When using the customization button to call up a focus position registered in the camera body 102, whether or not to execute the focus lens adjustment process is switched based on the user settings (modes 1 to 3). The only difference from the first embodiment is a portion of the flowchart showing the FP call process on the imaging lens 101 side and the camera body 102 side, and the rest is the same as the first embodiment.

[0149] 11 and 12, which include different flows, will be described regarding the processing when a customization button is used to call a focus position registered in the camera body 102. Fig. 11 is a flowchart showing FP call processing on the imaging lens 101 side according to embodiment 2. The processing in Fig. 11 is realized by loading a control program recorded in ROM 128 into RAM 129, and having the lens system control unit 110 control each unit of the imaging lens 101, execute arithmetic processing, and the like based on the control program.

[0150] 11 is the same as FIG. 4 except for S1101 and S1102, so only S1101 and S1102 will be explained.

[0151] In S1101, the lens system control unit 110 determines whether or not pressing of the customize button included in the lens operation unit 112 has started. If it is determined that pressing of the customize button has started, the process proceeds to S1102; otherwise, the process proceeds to S1101.

[0152] In S1102, the lens system control unit 110 transmits information indicating that the customize button has been started to be pressed to the camera body, and the process proceeds to S4008.

[0153] Fig. 12 is a flowchart showing FP call processing on the camera body 102 side according to embodiment 2. The processing in Fig. 12 is realized by loading a control program recorded in ROM 162 into RAM 163, and having the camera body system control unit 150 control each unit of the camera body 102, execute arithmetic processing, and the like based on the control program.

[0154] Since the processing in FIG. 12 is the same as that in FIG. 5 except for S1201, only S1201 will be explained.

[0155] In S1201, the camera body system control unit 150 determines whether or not it has received information indicating that the customization button included in the lens operation unit 112 has been pressed. If it is determined that information indicating that the customization button has been pressed has been received, the process proceeds to S5002; otherwise, the process proceeds to S1201.

[0156] <Other embodiments> The various controls described above as being performed by the lens system control unit 101 and the camera body system control unit 150 may be performed by a single piece of hardware. Also, the entire camera system may be controlled by multiple pieces of hardware (for example, multiple processors or circuits) sharing the processing.

[0157] 6A, the camera body system control unit 150 determines whether or not the manual focus adjustment process is possible based on the settings related to the manual focus adjustment operation, the focus lens drive state, and the state of the camera FP call button being pressed. The determined state of whether or not the manual focus adjustment process is possible is then set in the imaging lens 101. However, the lens system control unit 101 may also acquire the settings related to the manual focus adjustment operation and the state of the camera FP call button being pressed from the camera body 102, and determine and set the state of whether or not the manual focus adjustment process is possible in the lens system control unit 101. In this case, the lens system control unit 101 executes control to switch whether or not the focus adjustment process is possible.

[0158] Furthermore, in the above-described embodiment, as shown in FIG. 4 , in the FP call processing, the lens system control unit 101 determines whether the lens FP call button has been pressed and sets / cancels the lens FP call drive state based on the focus lens drive state. However, the camera body system control unit 150, rather than the lens system control unit 101, may control the drive of the focus lens 114 in response to pressing of the lens FP call button / camera FP call button. In this case, the camera body system control unit 150 acquires information on whether the lens FP call button has been pressed and the focus lens drive state from the imaging lens 101. The camera body system control unit 150 may set / cancel the lens FP call drive state based on the acquired information and state, or the camera body system control unit 150 may acquire information set in the imaging lens via a communication unit. Furthermore, the manual focus adjustment processing of FIG. 7 may also be performed by the camera body system control unit 150, rather than the lens system control unit 101. In this case, the camera body system control unit 150 acquires focus ring operation information from the imaging lens. The camera body system control unit 150 then controls the execution of manual focus adjustment processing in response to focus ring operation based on focus ring operation information, information on lens FP call driving in progress, whether manual focus adjustment processing is possible or not, and focus drive status.
