[Technical field]

[0001] The present invention relates to an imaging device and a control method and system thereof, and more particularly to a technique for notifying a subject of information about an image being distributed. [Background technology]

[0002] In the past, there was a problem that it was difficult for the subject to determine whether or not filming and streaming were in progress on-site. In response to this, Patent Document 1 discloses a technology that provides an on-air tally lamp that lights up during streaming and a cue tally lamp that lights up when a cue command is issued, allowing the subject to instantly recognize that filming and streaming are in progress by the on / off state of these lamps.

[0003] [Patent Document 1] JP 2013-243624 A Summary of the Invention [Problem to be solved by the invention]

[0004] Meanwhile, in recent years, an increasing number of imaging devices are being equipped with a function for capturing full-angle images and a crop function for capturing images with a narrower angle of view than the full-angle, and are capable of outputting both the full-angle image and the cropped image to multiple video terminals.

[0005] However, with the technology described in Patent Document 1, although the subject can tell that shooting and distribution is taking place because the on-air tally lamp and the cut tally lamp are illuminated, it is not possible to distinguish which angle of view of the image is being shot and distributed.

[0006] The present invention has been made in consideration of the above problems, and aims to enable the subject to recognize which image angle is being used when selecting and distributing one of images with multiple angles of view generated based on an image captured by a single imaging device. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the imaging device of the present invention has an output means for outputting an image obtained by capturing an image to an external device, a receiving means for receiving a tally signal indicating an image being distributed from the external device, a notification means, and a control means for controlling the notification means to make a notification based on the tally signal received by the receiving means, and the control means controls the notification means to make different notifications in a first case in which the tally signal received by the receiving means is a tally signal corresponding to an image with a first angle of view, and a second case in which the tally signal received by the receiving means is a tally signal corresponding to an image with a second angle of view different from the first angle of view. Effect of the Invention

[0008] According to the present invention, when one of images with multiple angles of view generated based on an image captured by a single imaging device is selected and distributed, it is possible to enable the subject to recognize which image angle of view is being used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, the embodiments will be described in detail with reference to the attached drawings. Note that the following embodiments do not limit the invention according to the claims. Although the embodiments describe a number of features, not all of these features are essential to the invention, and the features may be combined in any manner. Furthermore, in the attached drawings, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0011] <First embodiment> A first embodiment of the present invention will now be described.

[0012] 1 is a diagram showing a schematic configuration of an image delivery system according to the present embodiment, which includes an imaging device 10 that captures images and a delivery device 20 that delivers the captured images. The imaging device 10 and the delivery device 20 are connected via a communication line 30, and images are output from the imaging device 10 to the delivery device via the communication line 30, and delivery information related to delivery is output from the delivery device 20 to the imaging device 10.

[0013] The communication line 30 is configured so that the imaging device 10 can distinguish and receive a plurality of types of tally signals included in the distribution information output from the distribution device 20, and may be, for example, a wired communication line or a wireless communication line for communication via an antenna. In addition, the imaging device 10 may receive signals from the distribution device 20 by providing a plurality of contact input terminals that accept a binary voltage of on or off.

[0014] FIG. 2 is a block diagram showing an example of the configuration of the imaging device 10. As shown in FIG. The photographing lens 106 is a lens group consisting of multiple lenses including a zoom lens and a focus lens. The zoom lens is controlled by the zoom control unit 102, and changes the focal length to change the zoom magnification. The focus lens is controlled by the focus control unit 103, and adjusts the focus by moving in the optical axis direction.

[0015] The imaging unit 104 is an imaging element formed of a CCD, CMOS element, etc. that converts an optical image into an electric signal. The A / D converter 105 converts an analog signal output from the imaging unit 104 into a digital signal (image data). The barrier 101 covers the imaging system including the photographing lens 106 of the imaging device 10 to prevent the imaging system from becoming dirty or damaged.

[0016] Image processing unit 107 performs predetermined image processing such as pixel interpolation, resizing such as reduction, and color conversion on image data converted by A / D converter 105 or image data input via memory control unit 108. Furthermore, image data of a partial area set in advance can be cut out using operation unit 115 or touch panel 116 described later, and the cut-out image data (hereinafter referred to as a "cropped image") can be output in parallel with image data of the full angle of view (hereinafter referred to as a "full angle of view image"). The crop area, which indicates which area of ​​the full angle of view image is to be cut out and output as a cropped image, can be set by the user operating operation unit 115 to select an area in the full angle of view image.

[0017] Furthermore, the image processing unit 107 performs a predetermined calculation process using the captured image data, and the system control unit 50 performs exposure control and focus adjustment control based on the obtained calculation results. This allows TTL (through-the-lens) type AF (autofocus) processing, AE (autoexposure) processing, and EF (flash pre-flash) processing to be performed. Furthermore, the image processing unit 107 performs a predetermined calculation process using the captured image data, and also performs TTL type AWB (auto white balance) processing based on the obtained calculation results.

[0018] Moreover, the image data from the A / D converter 105 is written into the memory 109 via the image processing unit 107 and the memory control unit 108, or directly via the memory control unit 108 without via the image processing unit 107. The memory 109 stores image data obtained by the imaging unit 104 and converted into digital data by the A / D converter 105, and image data to be displayed on the display unit 110. The memory 109 has a storage capacity sufficient to store a predetermined number of still images and a predetermined period of moving images and audio. The memory 109 also serves as a memory for displaying images (video memory) when displaying image data read from the recording medium 122 and OSD (On Screen Display) data on the display unit 110.

[0019] The D / A converter 123 converts the image data for display stored in the memory 109 into an analog signal and supplies it to the display unit 110. As a result, the image data for display written in the memory 109 is displayed by the display unit 110 via the D / A converter 123.

[0020] The display unit 110 performs display on a display such as a liquid crystal display (LCD) in response to an analog signal from the D / A converter 123. In addition, the digital signal that has been A / D converted once by the A / D converter 105 and stored in the memory 109 is converted to analog by the D / A converter 123 and sequentially transferred to the display unit 110 for display, thereby allowing the display unit 110 to function as an electronic viewfinder, and a live view image is displayed. In addition, as described later, a display may be performed in response to a tally signal received by a tally signal receiving unit 124. Note that the display unit 110 is not limited to an LCD, and may be, for example, a display of another type such as an organic electroluminescence (EL) display. In addition, although the present embodiment is described as having the display unit 110, an external display device may be connected to an external output unit such as an HDMI (registered trademark) or SDI. Furthermore, the display unit 110 may be provided with a plurality of display output means.

[0021] The non-volatile memory 111 is a memory serving as an electrically erasable and recordable recording medium, and may be, for example, an EEPROM. Constants, programs, and the like for operating the system control unit 50 are stored in the non-volatile memory 111. These programs are programs for executing each process of this embodiment, which will be described later.

[0022] The system control unit 50 controls the entire imaging device 10. The system control unit 50 executes a program stored in the non-volatile memory 111 to realize each process of the present embodiment, which will be described later. The system control unit 50 also performs display control by controlling the memory 109, the D / A converter 123, the display unit 110, etc.

[0023] The system memory 113 uses, for example, a RAM, and stores constants and variables for the operation of the system control unit 50, programs read from the non-volatile memory 111, etc. The system timer 114 is a timing unit that measures the time used for various controls and the time of a built-in clock.

[0024] The operation unit 115 is an operation means for inputting various operation instructions to the system control unit 50, and includes various switching buttons such as a menu button, a cancel button, a cross key (upward key, downward key, leftward key, rightward key), a SET key, and an AF / MF. For example, when the menu button is pressed, a menu screen in which various settings can be made is displayed on the display unit 110. The user can intuitively make various settings using the menu screen displayed on the display unit 110, the cross key, and the SET key.

[0025] The touch panel 116 is a touch sensor that detects various touch operations on the display surface of the display unit 110 (the operation surface of the touch panel 116). The touch panel 116 and the display unit 110 can be configured as one unit. For example, the touch panel 116 is configured such that the light transmittance does not interfere with the display of the display unit 110, and is attached to the upper layer of the display surface of the display unit 110. By associating input coordinates on the touch panel 116 with display coordinates on the display surface of the display unit 110, it is possible to provide a GUI (Graphical User Interface) that makes it seem as if the user can directly operate the screen displayed on the display unit 110.

[0026] Using the operation unit 115 or touch panel 116, an arbitrary partial area for generating a cropped image can be set from the entire light receiving area (full angle of view) of the imaging unit 104. At the time of setting, a frame indicating the partial area being set is displayed on the display unit 110, so that the user can confirm which area of ​​the image will be output as the cropped image. Note that the frame displayed at this time may be erased after setting, or may be left displayed. Then, in the image processing unit 107, the image of the set partial area is cut out from the image of the full angle of view, thereby generating a cropped image.

[0027] A mode changeover switch 117 changes the operation mode of the system control unit 50 between a moving image shooting mode, a playback mode, and the like.

[0028] The grip zoom 112 is a seesaw type and is operated by being pressed. In the imaging device 10, a zoom speed (function) is assigned according to the amount of pressing (amount of operation) when the grip zoom 112 is pressed from a reference position. The system control unit 50 detects the amount of pressing of the grip zoom 112, and controls the zoom control unit 102 to change the position of the photographing lens 106 so that the zoom speed assigned to the amount of pressing becomes the one. In the grip zoom 112 of this embodiment, the greater the amount of pressing, the greater the amount of voltage change, and the system control unit 50 detects the amount of pressing by detecting the voltage output by the grip zoom 112.

[0029] The power switch 118 is a push button for switching the power of the imaging device 10 on and off. The power supply control unit 119 is composed of a battery detection circuit, a DC-DC converter, a switch circuit for switching the blocks to be energized, and detects whether a battery is installed, the type of battery, and the remaining battery power. The power supply control unit 119 also controls the DC-DC converter based on the detection results and instructions from the system control unit 50, and supplies the required voltage for the required period to each unit including the recording medium 122. The power supply unit 120 is composed of a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, an AC adapter, or the like.

[0030] The recording medium I / F 121 is an interface with the recording medium 122. The recording medium 122 is a recording medium for recording captured image data, and is configured from a semiconductor memory, a magnetic disk, or the like.

[0031] The tally signal receiving unit 124 receives a tally signal from the distribution device 20 via the communication line 30 . The tally signal identification unit 126 acquires the tally signal received by the tally signal receiving unit 124, determines which of the images output to the display unit 110 the tally signal corresponds to, and notifies the system control unit 50 of the result.

[0032] The tally light 125 is a light-emitting unit that lights up when a tally signal is received by a tally signal receiving unit. In this embodiment, the tally light 125 is configured with a plurality of LED lights of different colors, and lights up when the LED lights emit light. Alternatively, an external tally light or a tally light that can be connected wirelessly may be used as the tally light 125. The tally light control unit 127 receives notification of the tally signal information and the corresponding video information from the system control unit 50, and controls the lighting of the tally light 125. In addition, the tally signal information notified from the system control unit 50 and the corresponding video information may be multiple.

[0033] The frame control unit 128 receives notification of the tally signal information and the corresponding image information from the system control unit 50, generates a frame based on the tally signal information and the corresponding image information, and displays the generated frame on the display unit 110 in a superimposed manner.

[0034] The external output terminal 129 is a terminal that meets the SDI and HDMI (registered trademark) standards, and outputs image data generated by the imaging unit 104 and image processing unit 107 to an external device via the external output terminal 129. The imaging device 10 has multiple output terminals, including an SDI external output terminal and an HDMI external output terminal. Therefore, as an example, the imaging device 10 can output the full-angle image output from the image processing unit 107 to the distribution device 20 via SDI and the cropped image via HDMI (registered trademark) in parallel.

[0035] Next, a tally display process in the imaging device 10 of this embodiment will be described with reference to the flowchart of FIG. The processing of the flowchart in Fig. 3 is realized by executing a program according to this embodiment by the system control unit 50 of the imaging device 10. Note that all of the processing of the flowchart in Fig. 3 may be realized by a hardware configuration, or a part of the processing may be performed by a hardware configuration and the remaining processing may be executed by a software configuration based on a program.

[0036] In addition, it is assumed that a full-angle image and a cropped image are output from the imaging device 10 to the distribution device 20, and one of them is selected and distributed by the distribution device 20. However, images may be supplied to the distribution device 20 not only from the imaging device 10, but also from multiple imaging devices (not shown).

[0037] First, in S300, when a tally signal is input to the tally signal receiving unit 124, in S301, the tally signal identifying unit 126 identifies whether the tally signal input in S300 is a tally signal corresponding to a full-angle image. The following method is used for identifying the tally signal. The tally signal receiving unit 124 receives, together with the tally signal, identification information indicating whether the tally signal corresponds to an image output from an SDI external output terminal or an image output from an HDMI external output terminal. The tally signal identifying unit 126 determines an output terminal corresponding to the tally signal from the identification information, and identifies whether the received tally signal is a tally signal corresponding to a full-angle image depending on whether the image output from the output terminal corresponding to the tally signal is a full-angle image or a cropped image. The identification information may be information on the type of terminal such as HDMI (registered trademark) or SDI, or may be information on output terminal 1, output terminal 2, etc. Any form of information may be used as long as it is possible to identify which output terminal the tally signal corresponds to. If the tally signal corresponds to a full-angle image, the process proceeds to S302. If the tally signal does not correspond to a full-angle image, that is, if the tally signal corresponds to a cropped image, the process proceeds to S303.

[0038] If the input tally signal corresponds to a full-angle image, in S302, the frame control unit 128 generates a normal frame and displays it on the display unit 110, and the tally light control unit 127 controls the tally light 125 to indicate a normal tally state. As an example of the normal frame display, the frame control unit 128 generates a red frame surrounding the full-angle image and displays it on the display unit 110 superimposed on the image. Also, as an example of indicating the normal tally state, the red LED light of the multiple LED lights of the tally light 125 is turned on.

[0039] On the other hand, if the input tally signal corresponds to a cropped image, in S303, the frame control unit 128 generates a frame different from the normal one and displays it on the display unit 110, and the tally light control unit 127 controls the tally light 125 to indicate the different tally state from the normal one. As an example of displaying a frame different from the normal one, the frame control unit 128 generates a green frame surrounding the periphery of the cropped image and displays it superimposed on the image on the display unit 110. Also, as an example of indicating a different tally state from the normal one, the green LED light of the multiple LED lights of the tally light 125 is turned on.

[0040] When the process of S302 or S303 is completed, the tally display process ends.

[0041] FIG. 4(a) shows an example in which a frame 400 is superimposed around a full-angle image when the received tally signal corresponds to a full-angle image, and FIG. 4(b) shows an example in which a frame 401 is superimposed around a cropped image when the received tally signal corresponds to a cropped image.

[0042] As described above, according to the first embodiment, the color of the tally light is changed depending on whether it is determined that a full-angle image is being distributed or a cropped image is being distributed based on the tally signal. This makes it possible for the subject to recognize which angle of view image is being distributed, even when images of multiple angles of view, such as full-angle images and cropped images, are output from multiple external output terminals.

[0043] In the above example, for the normal (full angle of view) tally state, the tally light is lit in red, and the full angle of view frame is displayed on the display unit 110 in red, similar to the tally light, and for the tally state different from the normal (cropped image), the tally light is lit in green, and the crop frame is displayed on the display unit 110 in green, similar to the tally light. However, the present invention is not limited to these. The lighting color of the tally light and the full angle of view or crop frame may be a color other than red and green, and the lighting pattern of the tally light may be changed. In addition, the thickness of the line of the frame displayed on the display unit 110 may be changed, or the type of the line of the frame may be a dashed line, a dotted line, or the like. That is, the lighting form of the tally light and the display form of the frame displayed on the display unit 110 may be different when a full angle of view image is being distributed and when a cropped image is being distributed based on a tally signal output from the distribution device.

[0044] In the above embodiment, the display unit 110 displays the tally state by a frame, but the tally state may be displayed by an icon for displaying tally information or the like. In this case, the display color of the icon for displaying tally information is changed depending on whether a tally signal of the full angle of view is received or a tally signal of a cropped image is received, and the user is notified of the angle of view being distributed by the display color of the icon. In addition, the color of the tally light when a tally signal of the full angle of view is received is made the same as the color of the tally information display (frame or icon), and the color of the tally light when a tally signal of a cropped image is received is made the same as the color of the tally information display. By making the color of the tally light and the tally information display the same, it becomes easier to check the angle of view of the image being distributed.

[0045] In the above embodiment, when a tally signal is received, the frame 400 surrounding the full angle of view or the frame 401 surrounding the cropped image is displayed. However, these frames may be displayed not only when a tally signal is received, but also when a tally signal is not received. For example, in response to a crop area being set by the user, the frame 400 surrounding the full angle of view image and the frame 401 surrounding the cropped image indicating the cropped area are displayed on the display unit 110 as the field of view information of the image to be output. At this time, the frame 400 is displayed in a color corresponding to the full angle of view, and the frame 401 is displayed in a color corresponding to the cropped image. Then, when a tally signal corresponding to the full angle of view image is received, the display form of the frame 400 is changed (for example, displayed thick) and the tally lamp is turned on in a color corresponding to the full angle of view image. Then, when a tally signal corresponding to the cropped image is received, the display form of the frame 401 is changed (for example, displayed thick) and the tally lamp is turned on in a color corresponding to the cropped image. By notifying the tally state in this manner, the subject can check in advance the size and position of the cropped image area and the color corresponding to the clipped area by frame 401, from the display on display unit 110. In the above explanation, when a tally signal is received, the display format is changed by displaying the frame in a thicker color, but it is also possible to display the text "Distributing" without changing the frame display, or to display an icon indicating that streaming is in progress.

[0046] <Second embodiment> Next, a second embodiment of the present invention will be described. The configurations of the image delivery system and the imaging device in this embodiment are the same as those in the first embodiment described with reference to Figures 1 and 2, and therefore the description will be omitted. However, in the second embodiment, it is assumed that a plurality of partial regions can be set by the operation unit 115 or the touch panel 116, and the image processing unit 107 can cut out image data of the plurality of set partial regions and output a plurality of cropped images in parallel with the full angle image.

[0047] The distribution device 20 is also capable of distributing not only one image but also an image obtained by combining multiple images, and outputs multiple tally signals corresponding to the multiple images constituting the distributed image. The imaging device 10 is also capable of receiving multiple tally signals.

[0048] In the second embodiment, the tally display process in the above case will be described with reference to the flowchart in FIG. The processing of the flowchart in Fig. 5 is realized by executing a program according to this embodiment by the system control unit 50 of the imaging device 10. All of the processing of the flowchart in Fig. 5 may be realized by a hardware configuration, or a part of the processing may be performed by a hardware configuration and the remaining processing may be executed by a software configuration based on a program.

[0049] In addition, it is assumed that a full-angle image and multiple cropped images are output from the imaging device 10 to the distribution device 20, and the distribution device 20 selects and distributes one or more of the images. However, images may be supplied to the distribution device 20 not only from the imaging device 10, but also from multiple imaging devices (not shown).

[0050] First, in S500, when a tally signal is input to the tally signal receiving unit 124, in S501 the tally signal identifying unit 126 determines whether one tally signal is input in S500. If one tally signal is received, the process proceeds to S502, and if multiple tally signals are received, the process proceeds to S505.

[0051] In S502, the tally signal identification unit 126 identifies whether the tally signal input in S500 is a tally signal corresponding to the full-angle image. The tally signals input in S500 include tally signals corresponding to the full-angle image and tally signals corresponding to each of the multiple cropped images, and if the tally signal corresponds to the full-angle image, the process proceeds to S503, and if the tally signal does not correspond to the full-angle image, that is, if the tally signal corresponds to any of the multiple cropped images, the process proceeds to S504.

[0052] In S503, the same process as in S302 in Fig. 3 is performed. That is, the frame control unit 128 generates a normal frame and displays it on the display unit 110, and the tally light control unit 127 controls the tally light 125 to show the normal tally state.

[0053] On the other hand, if the input tally signal corresponds to any one of the plurality of cropped images, in S504, a frame different from the normal frame is generated and displayed at the position of the cropped image corresponding to the tally signal on the display unit 110. Furthermore, the tally light control unit 127 controls the display unit 110 to indicate a tally state different from the normal frame. As an example of displaying a frame different from the normal frame, an image in which a green frame generated by the frame control unit 128 is superimposed around a cropped image corresponding to the tally signal among the plurality of cropped images is displayed on the display unit 110. At this time, a frame of a different color may be set for each cropped image. Furthermore, as an example of indicating a tally state different from the normal state, a green LED light among the plurality of LED lights of the tally light 125 is turned on. At this time, a different color of the LED light may be set for each cropped image, and the LED light may be turned on to have a different color according to the cropped image.

[0054] On the other hand, if there is more than one tally signal, in S505, the tally signal identification unit 126 identifies whether the multiple received tally signals include a tally signal corresponding to a full-angle image, and if so, proceeds to S506, and if not, proceeds to S507.

[0055] In S506, similarly to S503, the frame control unit 128 generates a normal frame and displays it on the display unit 110, and the tally light control unit 127 controls the tally light 125 to indicate the normal tally state.

[0056] In S507, the frame control unit 128 generates and displays frames different from the normal frame by the number of tally signals corresponding to the cropped images, and the control of indicating a different tally state by the tally light 125 is executed in sequence and repeatedly. As an example of displaying a frame different from the normal frame, an image in which a yellow frame generated by the frame control unit 128 is superimposed around the cropped image corresponding to the tally signal is displayed on the display unit 110. At this time, if a red frame is superimposed around the entire image display as a normal frame display via S506, red and yellow frames are displayed. Also, as an example of indicating a different tally state from the normal one, a yellow LED light is turned on among the multiple LED lights of the tally light 125. At this time, if a red LED light is turned on as a normal display in S506, the red LED light and the yellow LED light are turned on in sequence and repeatedly.

[0057] When the process of S503, S504 or S507 is completed, the tally display process ends.

[0058] Fig. 6(a) shows an example in which a frame 600 is superimposed around a full-angle image and a frame 601 is superimposed around a cropped image when multiple tally signals are received and include a tally signal corresponding to the full-angle image. Fig. 6(b) shows an example in which frames 601 and 602 are superimposed around multiple cropped images when the multiple tally signals received do not include a tally signal corresponding to the full-angle image. Note that the frames 601 and 602 may be displayed in the same way, or may be displayed differently, for example, by changing the color or type of line.

[0059] As described above, according to the second embodiment, on the subject side, it becomes possible to distinguish between a case where a full-angle image is being delivered, a case where one cropped image is being delivered, a case where a full-angle image and at least one cropped image is being delivered, and a case where multiple cropped images are being delivered, and to recognize which angle of view image is being delivered.

[0060] Even when multiple images are being distributed at the same time, the photographer can recognize which image has which angle of view. Furthermore, by changing the display format, such as the frame color, it becomes even easier to recognize which image has which angle of view.

[0061] <Modification> In the above-described first and second embodiments, the case where a cropped image is generated in the imaging device 10 has been described. However, it is also possible to generate a cropped image in the distribution device 20.

[0062] In this case, when the distribution device 20 distributes the generated cropped image, it transmits a crop signal indicating the information and cropped area information indicating the range of the partial area indicated by the cropped image (for example, the center coordinates and horizontal and vertical lengths of the partial area) to the imaging device 10.
