Description

[Technical Field]

[0001] The present invention relates to a correction device that assists in photography using an imaging device having a plurality of imaging units with different imaging ranges. [Background technology]

[0002] Network-based camera systems are available. Such camera systems are used in a variety of places, including public institutions and stores, and are used in a variety of ways. A variety of cameras (network cameras that can be connected to a network) are also available for use in such camera systems. For example, network cameras are available that can be rotated in various directions, such as panning (left and right) and tilting (up and down), to freely change the shooting direction, and box-type network cameras that cannot change the shooting direction but are capable of high-magnification zoom shooting.

[0003] In video production, cameramen often operate multiple network cameras remotely. The captured footage may be distributed live or edited and broadcast. In this case, the cameraman can only understand the situation on the set from the camera footage (images captured by the network cameras). To understand the situation in areas not included in the camera footage, the cameraman must change the field of view and shooting direction of the network cameras.

[0004] To solve this problem, a network camera having multiple imaging units (a main imaging unit and a sub-imaging unit) has been provided. The main imaging unit is used to capture (image) the area that the cameraman wants to capture, as with a normal network camera, and the sub-imaging unit is used to capture (image) a wider area than the main imaging unit. This allows the cameraman to easily understand the situation of areas not included in the image captured using the main imaging unit from the image captured using the sub-imaging unit.

[0005] The network camera having the above-mentioned multiple imaging units must be installed so that each imaging unit can obtain an image suited to the intended purpose, and therefore installation of the network camera is difficult.

[0006] Patent Document 1 discloses a technology for displaying multiple indicators that indicate multiple angles of view corresponding to multiple optical systems, while Patent Document 2 discloses a technology for displaying an indicator that indicates the minimum recognizable character size.

[0008] However, while the techniques disclosed in Patent Documents 1 and 2 allow a user to easily configure one imaging unit to obtain a suitable image, it is not easy for the user to configure multiple imaging units to obtain a suitable image.

[0009] An object of the present invention is to enable a user to easily perform settings to obtain favorable images from all of the multiple imaging units included in an imaging device. [Means for solving the problem]

[0011] A second aspect of the present invention is a control method for an auxiliary device of an imaging device having a first imaging unit and a second imaging unit that captures a wider range than the range captured by the first imaging unit, characterized in that the control method includes a step of controlling so that a first auxiliary display related to the image captured by the first imaging unit and a second auxiliary display related to the image captured by the second imaging unit, which is of a type different from the type of the first auxiliary display, are displayed on the image captured by the second imaging unit.

[0012] A third aspect of the present invention is a program for causing a computer to function as each of the means of the auxiliary device.A fourth aspect of the present invention is a computer-readable storage medium storing a program for causing a computer to function as each of the means of the auxiliary device.

[0015] Example 1 A first embodiment of the present invention will be described. Fig. 1 is a block diagram showing an example of the configuration of an imaging device 100 (for example, a digital camera) according to the first embodiment. The imaging device 100 has a function as a correction device that assists in photographing using the imaging device 100. Note that the auxiliary device may be a device (for example, a personal computer, a smartphone, a tablet terminal, etc.) separate from the imaging device 100.

[0016] The imaging device 100 has an information processing unit 110, a first imaging unit 120, and a second imaging unit 130. Each of the first imaging unit 120 and the second imaging unit 130 has an imaging element such as a CCD image sensor or a CMOS image sensor, and acquires an image (captured image) using the imaging element. The range captured by the second imaging unit 130 is wider than the range captured by the first imaging unit 120. The information processing unit 110 performs various information processes (various controls) for the imaging device 100.

[0017] The information processing unit 110 includes a video development unit 101, an imaging control unit 102, an auxiliary parameter setting unit 103, and an image processing unit 104. 03, a first auxiliary parameter acquisition unit 104, a second auxiliary parameter acquisition unit 105, an auxiliary display determination unit 106, and a video display unit 107.

[0018] RAW data is obtained as image data of the captured images from each of the first imaging unit 120 and the second imaging unit 130. The video development unit 101 performs development processing on the RAW data obtained by the first imaging unit 120 and the RAW data obtained by the second imaging unit 130.

[0019] The imaging control unit 102 controls the imaging parameters of the first imaging unit 120 and the second imaging unit 130 based on the captured image after development processing has been performed by the video development unit 101. For example, the imaging control unit 102 controls the exposure, shutter speed, focus position, etc.

[0020] The auxiliary parameter setting unit 103 sets auxiliary parameters. The auxiliary parameters are parameters for assisting in photographing using the imaging device 100. The auxiliary parameter setting unit 103 sets a first auxiliary parameter related to the first imaging unit 120 and a second auxiliary parameter related to the second imaging unit 130. The method for setting the auxiliary parameters is not particularly limited, and the auxiliary parameter setting unit 103 may set the auxiliary parameters in response to an instruction from a user, or may automatically set the auxiliary parameters based on the captured image, the captured scene, or the like.

[0021] The first auxiliary parameter acquisition unit 104 acquires the first auxiliary parameters set by the auxiliary parameter setting unit 103. The second auxiliary parameter acquisition unit 105 acquires the second auxiliary parameters set by the auxiliary parameter setting unit 103.

[0022] The auxiliary display determination unit 106 determines an auxiliary display based on the first auxiliary parameter obtained by the first auxiliary parameter acquisition unit 104 and the second auxiliary parameter obtained by the second auxiliary parameter acquisition unit 105. The auxiliary display determination unit 106 determines a first auxiliary display related to the captured image obtained by the first imaging unit 120 and a second auxiliary display related to the captured image obtained by the second imaging unit 130. Then, the auxiliary display determination unit 106 performs image processing (for example, generating an item such as an indicator) so that the determined auxiliary display is displayed.

[0023] The video display unit 107 receives the captured image after development processing by the video development unit 101 from the imaging control unit 102 and displays it. At this time, the video display unit 107 also performs auxiliary display (for example, superimposing an item) determined by the auxiliary display determination unit 106. The image processing (image processing for auxiliary display) performed by the auxiliary display determination unit 106 may be image processing performed on the captured image after development processing by the video development unit 101 (for example, changing the brightness or color of the captured image).

[0024] Fig. 2 is a flowchart showing an example of the operation of the imaging device 100. The operation of Fig. 2 is realized, for example, by a CPU (not shown) reading and executing a program stored in a storage medium (not shown). The operation of Fig. 2 is also started, for example, in response to an instruction to set (change) an auxiliary parameter.

[0025] In step S200, the auxiliary parameter setting unit 103 sets the auxiliary parameters.

[0026] An example of a method for setting auxiliary parameters will be described with reference to Fig. 3. The user sets first auxiliary parameters 303 and second auxiliary parameters 304 while viewing a captured image 301 obtained by the first imaging unit 120 and a captured image 302 obtained by the second imaging unit 130. The auxiliary parameter setting unit 103 sets the first auxiliary parameters 303 and second auxiliary parameters 304 in accordance with the user's setting operations.

[0027] The auxiliary parameter setting unit 103 can set various auxiliary parameters with different types of auxiliary display. In FIG. 3, the first auxiliary parameter 303 indicates the display of the maximum zoom frame of the first image capture unit 120. FIG. 4 shows an example of the display of the maximum zoom frame. In FIG. 4, a maximum zoom frame 401 is displayed superimposed on a captured image 400 captured by the first image capture unit 120. The maximum zoom frame 401 indicates the area obtained when the optical zoom of the first image capture unit 120 is at its maximum, and indicates the minimum angle of view of the captured image captured by the first image capture unit 120. By looking at the maximum zoom frame 401, the user can easily grasp the minimum angle of view and determine whether the image capture device 100 is installed at an appropriate distance from the subject. If the image capture device 100 is not installed at an appropriate distance from the subject, the user moves the image capture device 100. The minimum angle of view of the captured image may be indicated by an item other than the maximum zoom frame.

[0028] Also, in FIG. 3, the second auxiliary parameter 304 indicates that a detectable (recognizable) subject item is displayed. FIG. 5 shows a display example of a detectable subject item. In FIG. 5, a detectable subject item 501 is displayed superimposed on a captured image 500 obtained by the second imaging unit 130. The detectable subject item 501 is an item that indicates the minimum image size of a subject (e.g., a human face) that can be detected from a captured image obtained by the second imaging unit 130. By looking at the detectable subject item 501, the user can easily grasp the minimum image size of a detectable subject. The user can then easily determine whether the image size of the subject in the captured image 500 is sufficient. If the image size of the subject in the captured image 500 is not sufficient, the user can zoom the second imaging unit 130 or move the imaging device 100 closer to the subject. Note that the form of the detectable subject item is not particularly limited.

[0029] The auxiliary display is not limited to the display of a maximum zoom frame or a detectable subject item. The auxiliary display may also be a display indicating the limit (maximum or minimum) of the angle of view or focal length of the captured image, or a display indicating the limit of the image size or subject distance of a subject detectable from the captured image. Because the color of a captured image varies depending on the lens, sensor, etc., of the imaging unit, image processing (color matching processing) may be performed to reduce the color difference between an image captured by one imaging unit and an image captured by another imaging unit. Therefore, the auxiliary display may be a color matching confirmation display for checking the color after the color matching processing. A plurality of first auxiliary parameters may be set corresponding to a plurality of first auxiliary displays, respectively, and a plurality of second auxiliary parameters may be set corresponding to a plurality of second auxiliary displays, respectively. To provide an auxiliary display that is easy for the user to understand, the first auxiliary display corresponding to the first auxiliary parameter may be changed depending on the type and number of other auxiliary parameters that have been set. Similarly, the second auxiliary display corresponding to the second auxiliary parameter may be changed depending on the type and number of other auxiliary parameters that have been set.

[0030] Returning to the description of FIG. 2, in step S201, the auxiliary display determination unit 106 determines whether or not an instruction to start auxiliary display has been received. The method for receiving the start instruction is not particularly limited. For example, the instruction to start auxiliary display may be given in response to the user pressing a button, or the instruction to start auxiliary display may be given automatically when the imaging device 100 is started (when the shooting mode is started) or when auxiliary parameters are set (settings are changed). The imaging device 100 waits until it receives an instruction to start auxiliary display, and upon receiving the start instruction, proceeds to step S202. If an instruction to change the settings of auxiliary parameters has been given, the process proceeds to step S200.

[0031] In step S202, the auxiliary display determination unit 106 acquires the first and second auxiliary parameters set in step S200 and determines the first and second auxiliary displays based on the acquired first and second auxiliary parameters. Then, the auxiliary display determination unit 106 performs image processing (for example, generating items such as indicators) so that the determined first and second auxiliary displays are displayed.

[0032] Fig. 6 shows an example of a screen displayed on the video display unit 107 after step S202. The screen in Fig. 6 is a screen when the first auxiliary parameter 303 (auxiliary parameter indicating that the maximum zoom frame of the first imaging unit 120 is to be displayed) and the second auxiliary parameter 304 (auxiliary parameter indicating that the detectable subject item is to be displayed) in Fig. 3 are set. In Fig. 6, a maximum zoom frame 601 of the first imaging unit 120 and a detectable subject item 602 are superimposed on a captured image 600 obtained by the second imaging unit 130.

[0033] The number of auxiliary displays to be displayed is not particularly limited, and three or more auxiliary displays may be displayed. Furthermore, the auxiliary display determination unit 106 may select at least one of a plurality of auxiliary displays corresponding to a plurality of set auxiliary parameters and control the display so that only the selected auxiliary display is displayed. The method for selecting an auxiliary display is not particularly limited, and the auxiliary display may be selected in response to a user instruction, or may be automatically selected based on the captured image, the captured scene, or the like. For example, even if the first auxiliary parameter 303 and the second auxiliary parameter 304 in FIG. 3 are set, only the maximum zoom frame may be displayed if a detectable object item is not required, such as when the subject can be detected appropriately. Furthermore, the information processing unit 110 may change one or both of the first auxiliary display and the second auxiliary display depending on the combination of the set first auxiliary parameter and second auxiliary parameter.

[0034] Furthermore, the type of auxiliary display to be displayed is not particularly limited. For example, the first auxiliary display may be another auxiliary display indicating the limit value of the angle of view or focal length of the image captured by the first imaging unit 120. The second auxiliary display may be another auxiliary display indicating the limit value of the image size or subject distance of the subject that can be detected from the image captured by the second imaging unit 130.

[0035] FIG. 7 shows an example of a screen in which a type of auxiliary display is different from that shown in FIG. 6. The screen in FIG. 7 is a screen in which a first auxiliary parameter indicating that the maximum zoom frame of the first imaging unit 120 is to be displayed and a second auxiliary parameter indicating that a color matching confirmation display is to be displayed are set. In FIG. 7, as in FIG. 6, a maximum zoom frame 701 of the first imaging unit 120 is superimposed on a captured image 700 acquired by the second imaging unit 130. The color of the area surrounded by the maximum zoom frame 701 in the captured image 700 acquired by the second imaging unit 130 is changed to match the color of the captured image acquired by the first imaging unit 120. A guide 702 indicating that such a change has been made is superimposed on the captured image 700.

[0036] Returning to the description of FIG. 2, in step S203, the auxiliary display determination unit 106 determines whether or not an instruction to end the auxiliary display has been received. The method for receiving the instruction to end the auxiliary display is not particularly limited. For example, the instruction to end the auxiliary display may be given in response to the user pressing a button, or the instruction to end the auxiliary display may be given automatically when a predetermined time has elapsed since the start of the auxiliary display. The imaging device 100 waits until it receives an instruction to end the auxiliary display, and upon receiving the instruction, proceeds to step S204. If an instruction to change the settings of the auxiliary parameters has been given, the process proceeds to step S200. If the time for the auxiliary display is being counted, the count value is reset.

[0037] In step S204, the auxiliary display determination unit 106 performs control to end the auxiliary display.

[0038] As described above, according to the first embodiment, a plurality of auxiliary displays corresponding to a plurality of imaging units are displayed on one captured image, respectively. This allows the user to easily check the plurality of auxiliary displays and easily perform settings (for example, moving the imaging devices or inputting parameters to the imaging devices) to obtain suitable images from all of the plurality of imaging units.

[0039] The number of imaging units may be more than two. In that case, three or more auxiliary displays corresponding to the three or more imaging units may be displayed on one captured image.

[0040] Example 2 A second embodiment of the present invention will be described below. Note that, in the following, a description of the same points as in the first embodiment (for example, the same configuration and processing as in the first embodiment) will be omitted, and only points different from the first embodiment will be described.

[0041] A suitable auxiliary display differs depending on the imaging scene. Therefore, in the second embodiment, scene information related to the imaging scene of the imaging device 100 is acquired (scene information acquisition process). Then, the auxiliary display (one or both of the first auxiliary display and the second auxiliary display) is changed according to the scene information. The imaging scene is, for example, the situation of the subject, such as whether or not there are multiple subjects separated in the imaging direction of the imaging device 100 (the direction in which the imaging device 100 is pointed; the optical axis direction of the imaging device 100).

[0042] The scene information is set (acquired) by the auxiliary parameter setting unit 103 in step S200 of Fig. 2. The method for setting (acquiring) the scene information is not particularly limited. The scene information may be set in response to an instruction from a user, or may be set automatically based on the captured image, the captured scene, etc.

[0043] For example, the information processing unit 110 may control the video display unit 107 to display a screen (setting screen) shown in Fig. 8, and scene information and auxiliary parameters may be set (acquired) in accordance with a user operation on the screen of Fig. 8. The screen of Fig. 8 includes a captured image 800 obtained by the second imaging unit 130, a group of radio buttons 801 for specifying scene information, and a group of check boxes 802 for specifying auxiliary parameters (auxiliary display).

[0044] The radio button group 801 includes a radio button for "subjects are close to each other," a radio button for "subjects a little farther apart," and a radio button for "subjects very far apart." The user selects one of these three radio buttons. When filming a play, multiple performers who are the subjects move within the limited space of a stage, so the distance from the imaging device 100 to the subjects (performers) is often the same for each performer. In this case, "subjects are close to each other." When filming a soccer match from behind the goal on a soccer field, multiple players who are the subjects move within the limited space of the soccer field, but a soccer field is much larger than a theater stage, for example. Therefore, the distance from the imaging device 100 to the subjects (players) often varies greatly among the multiple players. In this case, "subjects are very far apart" is selected. In a case between the above two cases, "subjects a little far apart" is selected.

[0045] Fig. 9 shows an example of a screen in which auxiliary display is performed. The screen of Fig. 9 is a screen in which a first auxiliary parameter indicating that the maximum zoom frame of the first imaging unit 120 is to be displayed and a second auxiliary parameter indicating that the detectable subject items are to be displayed are set, similar to the screen of Fig. 6. Furthermore, the screen of Fig. 9 is a screen in which "subjects are very far apart" is selected.

[0046] 9, a maximum zoom frame 901 of the first imaging unit 120 and a detectable subject item 902 are superimposed on a captured image 900 obtained by the second imaging unit 130. The captured image 900 shows two people, and the maximum zoom frame 901 is displayed to match the person in the foreground, assuming that the person in the background will be photographed. The detectable subject item 902 is a boundary line (depth limit line) that indicates the depth position of a detectable subject, and is different from the detectable subject item 602 in FIG. 6. Note that when "subjects are close to each other" is selected, the detectable subject item 602 in FIG. 6 is displayed. When the user looks at the detectable subject item 902, Assume that the image capturing device 100 is moved closer to the two people so that the person in the back is in front of the detectable subject item 902. However, if the image capturing device 100 is moved too close to the person in the front, the person in the front cannot be detected. For this reason, FIG. 9 also displays an item 903 indicating the maximum movement distance of the image capturing device 100 (the movement distance that makes the distance from the image capturing device 100 to the person in the front match the shortest distance at which the person can be detected).

[0047] As described above, according to the second embodiment, the auxiliary display is changed depending on the shooting scene, thereby making it possible to provide an auxiliary display that is easier for the user to understand.

[0048] Although an example in which the auxiliary display is changed according to the distance between the subjects has been described, the present invention is not limited to this. The auxiliary display may also be changed according to the position or movement pattern of the subject. When photographing a pedestrian walking on a sidewalk as a subject, the auxiliary display may be changed taking into account that the subject is walking on the sidewalk. For example, the display position of the auxiliary display item may be moved outside the sidewalk area so as not to interfere with confirmation of the sidewalk.

[0049] The various controls described above may or may not be performed by a single piece of hardware (e.g., a processor or circuit). The entire device may be controlled by multiple pieces of hardware (e.g., multiple processors, multiple circuits, or a combination of one or more processors and one or more circuits) sharing the processing.

[0050] The above processor is a processor in the broad sense, and includes general-purpose processors and dedicated processors. General-purpose processors include, for example, CPUs (Central Processing Units), MPUs (Micro Processing Units), and DSPs (Digital Signal Processors). Dedicated processors include, for example, GPUs (Graphics Processing Units), ASICs (Application Specific Integrated Circuits), and PLDs (Programmable Logic Devices). Programmable logic devices include, for example, FPGAs (Field Programmable Gate Arrays) and CPLDs (Complex Programmable Logic Devices).

[0051] Although the embodiments of the present invention have been described in detail, the present invention is not limited to these specific embodiments, and various forms within the scope of the gist of the present invention are also included in the present invention. Furthermore, each of the above-described embodiments merely represents one embodiment of the present invention, and each embodiment can be combined as appropriate.

[0052] (Other embodiments) The present invention can also be realized by a process in which a program that realizes one or more functions of the above-described embodiments is supplied to a system or device via a network or a storage medium, and one or more processors in the computer of the system or device read and execute the program, or by a circuit that realizes one or more functions.
