Description

Technical Field

[0001] The present invention relates to a technique for remotely operating an imaging device such as a camera.

Background Art

[0002] There is a method in which an information processing device such as a smartphone, a tablet device, or a PC performs wired or wireless communication with an imaging device and remotely controls the imaging device from the information processing device.

[0003] Remote control of the imaging device by the information processing device is performed by the imaging device receiving a control signal from the information processing device via a communication means.

[0004] In addition, there is a configuration in which the imaging device can transmit the live view (hereinafter, LV) of the imaging device and an on-screen display (OSD) on which control information of the imaging device displayed on the display of the imaging device is described to the information processing device. In this configuration, the information processing device can display the LV and OSD of the imaging device received from the imaging device on the display of the information processing device. By displaying the LV and OSD of the imaging device on the display on the information processing device, the imaging device can be remotely controlled while checking both images.

[0005] On the other hand, when the postures of the LV and a display device such as the display of the imaging device are different, there is a technique of avoiding the LV being displayed horizontally when viewed on the display of the imaging device by rotating the LV by 90 degrees and displaying it on the display of the imaging device (Patent Document 1).

[0006] Furthermore, when displaying the LV on the display of an information processing device or the like, the posture of the LV may be different from that of the display of the information processing device or the like. In the above state, when rotation of the LV other than in 90-degree units is required, it becomes impossible to display the LV on the display at a normal angle. Therefore, there is a technique for solving this problem by attaching angle information at the time of shooting to the LV and rotating and displaying the LV in the reverse direction on the display in a form that cancels out the angle information (Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0008] However, in the above conventional example, when transmitting the LV and the OSD from the imaging device and displaying the LV and the OSD on the information processing device, if the display posture of the OSD is different from the posture of the LV, it may not be possible to visually recognize the OSD on the display of the information processing device at a normal angle only with the posture information of the LV.

Means for Solving the Problems

[0009] To solve this problem, for example, the imaging system of the present invention has the following configuration. That is, An imaging system including a camera and a terminal that remotely controls the camera in communication with the camera, Transmission means for transmitting a live view, an OSD (On Screen Display), and respective posture information obtained by the camera from the camera toward the terminal, And display means for displaying on the screen of the terminal based on the live view, the OSD, and respective posture information. When the display means displays either the live view or the OSD, it is displayed in the orientation based on the posture information of the display target. When both the live view and the OSD are displayed, the orientations of the OSD and the live view are determined based on the posture information of the OSD and superimposed for display.

Advantages of the Invention

[0010] According to the present invention, the OSD displayed on the display of a terminal such as an information processing apparatus assumes a normal display posture, and the visibility can be improved in remote operation.

Modes for Carrying Out the Invention

[0012] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims. Although a plurality of features are described in the embodiments, not all of these plurality of features are essential to the invention, and the plurality of features may be arbitrarily combined. Further, in the accompanying drawings, the same or similar configurations are given the same reference numerals, and duplicate descriptions are omitted.

[0013] FIG. 1 is a block configuration diagram of a camera 100 which is a member of the imaging system of the present embodiment. Also, FIG. 2 is a block configuration diagram of a terminal 200 such as an information processing apparatus which is another member of the video processing system. The camera 100 in the embodiment is assumed to be a still camera or a video camera, but is not particularly limited thereto. In short, any device having a camera function (imaging function) may be used, for example, a smartphone, a tablet, etc. may also be used. Also, the terminal 200 will be described as a personal computer in the embodiment, but is not particularly limited thereto. For example, the terminal 200 may be any device having a display function and various instruction input functions, and for example, a mobile phone such as a smartphone, a so-called tablet terminal, a television, etc. may also be used.

[0014] In FIG. 1, the camera 100 is composed of a CPU 101, a volatile memory 102, a non-volatile memory 103, a camera unit 104, a camera signal processing unit 105, a communication I / F 106, a connector / antenna 107, a recording medium I / F 108, a recording medium 109, an input I / F 110, an operation unit 111, an output I / F 112, a display 113, and an internal bus 120. Each unit is controlled by a program operating on the CPU 101, and the units connected to the internal bus 120 can exchange data with each other via the internal bus 120.

[0015] The volatile memory 102 is for appropriately recording programs, variables, working temporary data, etc. that the CPU 101 needs during operation, and is typically a DRAM. The non-volatile memory 103 stores and holds various programs and parameters for the operation of the CPU 101, and is typically a ROM or a flash memory.

[0016] The CPU 101 controls each part of this camera 100 by using the volatile memory 102 as a work memory according to a program stored in the non-volatile memory 103 or the recording medium 109.

[0017] The camera unit 104 forms an optical image of the subject, converts the optical image into an analog electrical signal, and then converts it into a digital signal. The camera signal processing unit 105 compresses and encodes the digital signal converted by the camera unit 104 at a predetermined bit rate and in a format based on the control of the CPU 101, or decodes the video compression-encoded data.

[0018] The communication I / F 106 communicates with the terminal 200 via the connector / antenna 107 based on the control of the CPU 101.

[0019] The recording medium I / F 108 connects a recording medium 109 such as an HDD or a non-volatile memory, and reads data from the connected recording medium 109 and writes data to the recording medium 109 based on the control of the CPU 101. Note that the recording medium 109 that can be connected by the recording medium I / F 108 may be a removable non-volatile memory such as a memory card connected via a socket (not shown).

[0020] The input I / F 110 receives user operations at the operation unit 111, generates a control signal according to the operations, and supplies it to the CPU 101. For example, as an input device that receives user operations, the operation unit 111 has an input device for character information such as a zoom operation lever or a keyboard, a pointing device such as a mouse or a touch panel, etc. It also includes devices that can be remotely operated such as an infrared remote control. Note that the touch panel is an input device configured such that coordinate information corresponding to the position where it is touched is output with respect to, for example, a flatly configured input unit. Thereby, the camera 100 can be made to perform operations according to user operations.

[0021] The output I / F 112 outputs a display signal for causing the display 113 to display based on display data such as a GUI generated by the CPU 101 according to a program and a live view (LV) composed of digital signals obtained from the camera unit 104. The LV can be displayed in a still image shooting standby state, a moving image shooting standby state, and during moving image recording, and the captured subject image is displayed almost in real time. When a touch panel is used as the operation unit 111, the operation unit 111 and the display 113 can be integrally configured. For example, the touch panel is configured such that the light transmittance does not interfere with the display of the display 113 and is attached to the upper layer of the display surface of the display 113. Then, the input coordinates on the touch panel and the display coordinates on the display 113 are associated with each other. Thereby, a GUI can be configured such that the user can directly operate the screen displayed on the display 113.

[0022] The attitude sensor 114 detects the attitude (gravity direction) of the camera 100. As a result, the CPU 101 can determine in what attitude the user is holding and posing the camera 100. That is, the CPU 101 can determine whether it is posed for portrait shooting or for landscape shooting. Note that portrait refers to a state where the vertical length of the image to be taken is longer than the horizontal length, and landscape refers to a state where the vertical length is shorter than the horizontal length.

[0023] Also, in the embodiment, there are two types of OSD (On Screen Display) displays, portrait and landscape. Displaying the OSD in portrait means that the vertical length of the circumscribed rectangle including the symbol group such as characters and symbols representing various states and setting values related to shooting is longer than the horizontal length. Conversely, displaying the OSD in landscape means that the vertical length of the circumscribed rectangle including the symbol group such as characters and symbols is shorter than the horizontal length. Although there are a wide variety of types of OSD to be displayed, the CPU 101 knows in advance the layout of the SD to be displayed next. That is, the CPU 101 also knows whether the OSD to be displayed will be in portrait or landscape.

[0024] In FIG. 2, the terminal 200 is composed of a CPU 201, a volatile memory 202, a non-volatile memory 203, a communication I / F 204, a connector / antenna 205, a recording medium I / F 206, a recording medium 207, an input I / F 208, an operation unit 209, an output I / F 210, a display 211, and an internal bus 220. Since the reference numerals 201 to 211 basically have the same functions as the components with the same names in FIG. 1, their descriptions are omitted.

[0025] The camera 100 and the terminal 200 will communicate with each other via the communication I / F 106 and the communication I / F 204, respectively. The type of communication interface, including wired / wireless, does not matter. Also, the user of the terminal 200 views the live view and OSD displayed on the display 211 and performs various operations for remotely controlling the camera 100. The CPU 201 of the terminal 200 performs remote operations by transmitting various commands corresponding to this operation to the camera 100. However, since the main focus of the present invention is on the processing related to the display of the live view and OSD transmitted from the camera 100, the description of remote control is omitted.

[0026] Hereinafter, with reference to FIGS. 1, 2, and 3, the schematic operation of remote control in this embodiment will be described.

[0027] When the user inputs an instruction to execute remote control from the operation unit 111 of the camera 100, the CPU 101 of the camera 100 sets the communication I / F 106 to a communicable state.

[0028] Furthermore, when the user operates the operation unit 209 (including a touch panel) of the terminal 200 and inputs an instruction to start a program such as an application browser necessary for communication connection processing and remote control, the CPU 201 of the terminal 200 controls the communication I / F 204 according to the program stored in the non-volatile memory 203 or the recording medium 207, starts communication with the camera 100, and performs connection processing.

[0029] When the connection processing (communication establishment) between the camera 100 and the terminal 200 is completed, the camera 100 and the terminal 200 start processing necessary for remote control.

[0030] FIG. 3 shows a configuration example in which, in remote control, the camera 100 transmits the LV301 and the OSD302 stored in the volatile memory 102 to the terminal 200 under the control of the CPU 101.

[0031] Under the control of CPU 101, the camera 100 can add and transmit LV301 (video data captured by the camera unit 104), OSD302, and their respective attitude information or display directions as supplementary information. The attitude information is information indicating the angle / screen direction with respect to the display reference during shooting by the camera 100. The attitude information of LV301 follows the attitude detected by the attitude sensor 114, and the attitude information of the OSD is determined by the type of OSD information (or the type of items to be displayed) to be displayed. The display direction is an indication of the rotation direction when LV301 and OSD302 are rotated and displayed on the terminal 200. LV301 and OSD302 basically have the same attitude information and display direction. However, when specific operations such as menu display are performed on OSD302, OSD302 may have different attitude information and display information from LV301. Under the control of CPU 201, the terminal 200 displays LV301 and OSD302 received from the camera 100 in the image display area 304 in a form where OSD302 is superimposed on LV301. The image display area 304 can perform image display of LV301 and OSD302 similar to the image display area 303 of the camera 100 under the control of CPU 201.

[0032] Under the control of CPU 201, the terminal 200 can rotate LV301 and OSD302 using the supplementary information of LV301 and OSD302 and display them in the image display area 304. When OSD302 is displayed, CPU 201 uses only the supplementary information of OSD302 for the rotation of LV301 and OSD302. However, when the image display area 304 is larger than the preset size, CPU 201 determines the display direction by using the supplementary information of LV301 and OSD302 for the rotation of LV301 and OSD302 respectively. As a result, the characters, icons, etc. of OSD302 displayed in the image display area 304 are always displayed in the correct attitude.

[0033] The reference numeral 305 in the figure is a group of icons for remote control. By operating these icons by the user, a remote control instruction can be transmitted to the camera 100.

[0034] Reference numeral 306 is an icon for the user to select turning on / off of LV301. Normally, LV301 is displayed, but depending on the processing capacity and communication load state of the terminal 200, it is possible to turn off the LV display (make the LV non-displayed) by operating this icon, giving priority to operability.

[0035] Reference numeral 307 is an icon for the user to select turning on / off of OSD302. Normally, OSD302 is displayed, but depending on the processing capacity and communication load state of the terminal 200, it is possible to turn off the OSD display by operating this icon, giving priority to operability.

[0036] Figures 4(a) to (c) are sequences showing the rotation and display processing of LV301 and OSD302 by the camera 100 and the terminal 200. This sequence is realized by the CPU 101 of the camera 100 controlling each part of the camera 100 based on a program stored in the non-volatile memory 103 or the recording medium 109, and the CPU 201 of the terminal 200 controlling each part of the terminal 200 based on a program stored in the non-volatile memory 203 or the recording medium 207.

[0037] Figure 4(a) shows a sequence in which the CPU 201 of the terminal 200 sets the display direction based on the attitude information of LV301 and OSD302 and rotates and displays LV301 and OSD302 in the image display area 304.

[0038] Reference numeral 401 is a transmission request from the terminal 200 to the camera 100 for the LV301, the OSD302, and the attitude information of the LV301 and the OSD302. Reference numeral 402 indicates a response from the camera 100 to the terminal 200 (transmission of the attitude information of the LV301 and the OSD302) to the request 401. This attitude information includes information indicating the gravity direction of the LV301 and the gravity direction of the OSD (or information indicating the up (or down) direction when displayed in landscape). The attitude with respect to the LV301 is determined by the attitude sensor 114. Also, the attitude of the OSD is determined according to the layout of the OSD to be displayed. Reference numeral 403 indicates a process in the terminal 200 of setting the display direction based on the attitude information of the LV301 and the OSD302. And reference numeral 405 is a process of rotating the LV301 and the OSD302 in the set display direction and displaying them in the image display area 304.

[0039] FIG. 4(b) shows a sequence in which the CPU 101 of the camera 100 sets the display direction based on the attitude information of the LV301 and the OSD302, and the CPU 201 of the terminal 200 rotates and displays the LV301 and the OSD302 in the image display area 304.

[0040] Reference numeral 405 is a request for obtaining the display direction of the LV301 and the OSD302 from the terminal 200 to the camera 100. Reference numeral 406 indicates a process in the camera 100 of setting the display direction based on the attitude information of the LV301 and the OSD302. And reference numeral 407 is the transmission of the LV301 and the OSD302 from the camera 100 to the terminal 200 and the transmission of the setting information related to their display directions. Reference numeral 408 indicates that the terminal 200 performs the rotation and display process of the LV301 and the OSD302 based on the received information.

[0041] Figure 4(c) shows the sequence in which, under the control of the CPU 201 of the terminal 200, the CPU 101 of the camera 100 sets the display direction based on the attitude information of the LV 301 and the OSD 302, rotates the LV 301 and the OSD 302, and then transmits them to the terminal 200. After receiving this, under the control of the CPU 201 of the terminal 200 that has received it, the LV 301 and the OSD 302 are displayed in the image display area 304.

[0042] The reference numeral 409 shown in the figure is a transmission request for the LV 301 and the OSD 302 from the terminal 200 to the camera 100. The reference numeral 410 is a process in which the CPU 101 of the camera 100 sets the display direction based on the attitude information of the LV 301 and the OSD 302. The reference numeral 411 is a process in which the CPU 101 of the camera 100 rotates the LV 301 and the OSD 302 according to the set direction. The reference numeral 412 is the data transmission of the LV 301 and the OSD 302 from the camera 100 to the terminal 200. And the reference numeral 413 is a display process of the LV 301 and the OSD 302 in the image display area 304 by the CPU 201 of the terminal 200.

[0043] Figure 5 is a diagram showing the flow of setting the display direction based on the attitude information of S403, S406, S410, SLV301, and OSD302 in FIGS. 4(a) to (c).

[0044] For the sake of simplicity of explanation, hereinafter, the process of FIG. 4 will be described as the process of S403, that is, the process of the CPU 201 of the terminal 200. That is, the CPU 201 of the terminal 200 receives the respective attitude information of the LV 301 and the OSD 302 from the camera 100, and based on the received information, performs a process of setting the respective display directions.

[0045] First, at S501, the CPU 201 determines the display mode of the terminal 200. The display mode follows the on (display) / off (non-display) settings by the icons 306 and 307. When both are set to "off (non-display)", since only the display process is not performed, there are three cases to be determined: {LV301 on, OSD302 off}, {LV301 off, OSD on}, and {LV301 on, OSD on}.

[0046] At S501, when the CPU 201 determines that the display mode of the terminal 200 is {LV301 on, OSD302 off}, the process proceeds to S502. At this S502, the CPU 201 determines the orientation of LV301. When it is determined that the orientation of LV301 is portrait, the CPU 201 proceeds the process to S505 and decides to display LV301 in portrait. Also, at S502, when it is determined that the orientation of LV301 is landscape, the CPU 201 proceeds the process to S506 and decides to display LV301 in landscape.

[0047] At S501, when the CPU 201 determines that the display mode of the terminal 200 is {LV301 off, OSD302 on}, the process proceeds to S503. At this S503, the CPU 201 determines the orientation of OSD302. When it is determined that the orientation of OSD302 is portrait, the CPU 201 proceeds the process to S507 and decides to display OSD302 in portrait. Also, at S503, when it is determined that the orientation of OSD302 is landscape, the CPU 201 proceeds the process to S508 and decides to display OSD302 in landscape.

[0048] In S501, when the CPU 201 determines that the display mode of the terminal 200 is {LV301 on, OSD302 on}, the process proceeds to S504. In this S504, the CPU 201 determines the orientation of the OSD 302. If it is determined that the orientation of the OSD 302 is portrait, the CPU 201 proceeds to S509 and decides to display both LV301 and OSD302 in portrait. Also, in S504, if it is determined that the orientation of the OSD 302 is landscape, the CPU 201 proceeds to S510 and decides to display both LV301 and OSD302 in landscape. That is, the orientation of the OSD is given priority over the orientation of LV301.

[0049] The above was the process of reference numeral 403 in FIG. 4(a). After that, however, the CPU 201 of the terminal 200 will display LV301 (when on) and OSD302 (when “on”) in accordance with the determined display direction at reference numeral 404.

[0050] Note that when applied to the process of reference numeral 406 and S410 in FIG. 4, the subject that performs that process is the CPU 101 of the camera 100. Therefore, when the CPU 201 of the terminal 200 sends an information acquisition request to the camera 101 at reference numerals 405 and 409, it also sends the current display mode (LV, on / off status information for each of OSD) at the same time. Also, particularly when applied to the process of 410, the CPU 101 will perform a rotation process on LV301 according to the orientation of the OSD 302 (reference numeral 411).

[0051] FIG. 6(a) shows a case where only LV301 is displayed under the control of the CPU 201 of the terminal 200, and shows LV301 displayed in the image display area 304 after S506 in FIG. 5 is executed. As shown in the figure, LV301 is displayed in landscape.

[0052] Figure 6(b) shows the case where only the OSD 302 is displayed under the control of the CPU 201 of the terminal 200, and it is the OSD 302 displayed in the image display area 304 after S508 in FIG. 5 is executed. As shown in the figure, the OSD 302 is displayed in landscape mode.

[0053] Figure 6(c) shows the case where both the LV 301 and the OSD 302 are displayed under the control of the CPU 201 of the terminal 200 (specifically, the OSD 302 is superimposed on the LV 301), and it shows the LV 301 and the OSD 302 displayed in the image display area 304 after S510 in FIG. 5 is executed. As shown in the figure, both the LV 301 and the OSD 302 are displayed in landscape mode.

[0054] Figure 7(a) shows the case where only the LV 301 is displayed under the control of the CPU 201 of the terminal 200, and it is the LV 301 displayed in the image display area 304 after S505 in FIG. 5 is executed. As shown in the figure, the LV 301 is displayed in portrait mode.

[0055] Figure 7(b) shows the case where only the OSD 302 is displayed under the control of the CPU 201 of the terminal 200, and it is the OSD 302 displayed in the image display area 304 after S507 in FIG. 5 is executed. As shown in the figure, the OSD 302 is displayed in portrait mode.

[0056] Figure 7(c) shows the case where the LV 301 and the OSD 302 are displayed under the control of the CPU 201 of the terminal 200, and it is the LV 301 and the OSD 302 displayed in the image display area 304 after S509 in FIG. 5 is executed. As shown in the figure, both the LV 301 and the OSD 302 are displayed in portrait mode.

[0057] Figure 8(a) shows the case where the LV 301 and the OSD 302 are displayed under the control of the CPU 201 of the terminal 200, and it is the LV 301 and the OSD 302 displayed in the image display area 304 after S510 in FIG. 5 is executed. As shown in the figure, the OSD 302 is displayed in landscape mode, and the LV 301 is also displayed in landscape mode (rotated 90 degrees with respect to the gravity direction).

[0058] In addition, when the display 211 of the terminal 200 has a sufficient size for the LV 301 and the OSD 302 (for example, when the vertical and horizontal directions of the display area 304 are both higher than the resolution of any side of the captured image), the LV 301 and the OSD 302 may be displayed in the optimal directions based on their respective attached information under the control of the CPU 201 of the terminal 200. FIG. 8(b) shows this state, that is, the LV 301 is in portrait display and the OSD 302 is in landscape display.

[0059] As described above, according to this embodiment, the OSD displayed on the terminal (information processing device) on the remote operation side is in an upright posture, and the visibility can be improved in remote operation.

It can also be realized by a circuit (for example, ASIC) that realizes one or more functions.
