Description

  The present technology relates to an imaging device, an imaging processing method, and an imaging system.

  As display of imaging information in a camera device, for example, there is display of a lens focus state. Conventionally, as a display method, it is known to emphasize and display high frequency components of a captured image. Alternatively, as a display method, it is known to magnify and scale any necessary area to convey the focus state of the lens to the photographer. However, in the case of these display methods, it is not possible to constantly check the true state of the imaging main line signal because one display switches and displays the imaging main line signal. Also, conventionally, a method has been proposed in which a main line image and an enlarged image are combined and displayed on one screen (for example, see Patent Document 1). However, in this case, the display is within one screen, and simultaneous confirmation of true main line images has not been achieved.

  Further, as display of imaging information in a camera device, for example, there is display of a luminance level of an imaging signal. Also regarding this display, although the area of the level designated in advance is replaced with a color or a specific image for identification, it is not possible to always check the imaging main line.

  Further, as display of imaging information in the camera device, for example, there is display of status information at the time of imaging. Conventionally, for this display, for example, status information at the time of imaging is often superimposed as characters on the upper and lower portions of the display screen of the captured image, but the overlapping unit hides the image, thus causing problems in imaging There was also.

  Also, conventionally, in the case of a system in which an image of an arbitrary camera device is converted to an on-air image using a plurality of camera devices, the on-air image can be transmitted as a return image to each camera device and can be confirmed. There is. Also in this case, there is one display for displaying on the imaging device side, and it is necessary to switch the signal, and the operation while checking the on-air image for a long time is impossible.

  An object of the present technology is to enable display of information that becomes effective when imaging, without affecting the confirmation display of the imaging main line signal.

The concept of this technology is
A first output unit that outputs a first image signal for displaying a first image corresponding to an image based on a captured image signal;
There is provided a camera apparatus including a second output unit that outputs a second image signal for displaying a second image having information that becomes effective when imaging.

  In the present technology, the first output unit outputs the first image signal for displaying the first image corresponding to the image by the captured image signal. In addition, the second output unit outputs a second image signal for displaying a second image having information that becomes effective when imaging. For example, the first image signal and the second image signal may be generated by the device itself and / or sent as a return signal from the camera control unit.

  Also, for example, the second image may be set to be an enlarged image corresponding to a part of the first image. In this case, for example, the captured image signal is an image signal of 4K resolution, and the first image signal is an image of the HD resolution of the same image frame as the captured image signal obtained by down-converting the captured image signal. It may be a signal, and the second image signal may be an HD resolution image signal obtained by cutting out a part of the captured image signal.

  Also, for example, even if the second image is an image showing an area corresponding to a predetermined luminance level range of the captured image signal in the first image in a color designated in advance or a specific luminance pattern. Good. Also, for example, the second image may be an image including information indicating an imaging state. Also, for example, the second image may be an on-air image.

  Also, for example, the second image signal is an image signal sent as a return signal from the camera control unit, and the second image is a magnified image corresponding to the first image or a part of the first image. May be an image including a display indicating the location of focusing.

  Also, a standard processing unit that processes a captured image signal to obtain a first image signal, a signal reception unit that receives the first image signal sent as a return signal from the camera control unit, and a standard processing unit The first image signal received by the first image signal or the signal reception unit may be selectively extracted and sent to the first output unit. In this case, for example, when there is a control signal of the first selector from the camera control unit, the first selector may be controlled to be switched based on the control signal.

  In addition, for example, a second selector may be further provided, which extracts any one second image signal from the plurality of second image signals and sends the second image signal to the second output unit. In this case, for example, the second selector selects the second image signal obtained by the enlargement processing unit, the second image signal obtained by the level display processing unit, and the second image signal obtained by the status generation module. Alternatively, the second image signal received by the signal receiving unit may be selectively extracted and sent to the second output unit. And, in this case, when there is a control signal of the second selector from the camera control unit, the second selector may be controlled to be switched based on this control signal.

  Here, the second image signal obtained by the enlargement processing unit is an image signal for processing the captured image signal to display an enlarged image corresponding to a part of the first image as a second image. Further, the second image signal obtained by the level display processing unit processes the captured image signal, and an area corresponding to a predetermined luminance level range of the captured image signal in the first image is previously designated in color or It is an image signal for displaying the image shown by a specific luminance pattern as a 2nd image. The second image signal obtained by the status generation module is an image signal for displaying an image including information indicating an imaging state as a second image. The second image signal received by the signal receiving unit is an image signal sent as a return signal from the camera control unit.

  As described above, in the present technology, the first image signal for displaying the first image corresponding to the image according to the captured image signal is output, and the second image having information that becomes effective when imaging is selected. It outputs a second image signal to be displayed. Therefore, it becomes possible to display information that is effective when imaging, without affecting the confirmation display of the imaging main line signal.

Also, the other concept of this technology is

The camera body is equipped with two indicators attached so that the user can monitor simultaneously,
The camera body is
A first output unit that outputs a first image signal for displaying a first image corresponding to an image according to a captured image signal and supplies the first image signal to one of the two displays;
There is provided a camera apparatus having a second output section for outputting a second image signal for displaying a second image having information which becomes effective in imaging and supplying the second image signal to the other of the two displays.

  In the present technology, two displays are attached to the camera body in a state where the user can simultaneously monitor. And this camera body has a 1st output part and a 2nd output part. For example, the two displays may both be such that they are of the release type. Also, for example, the two indicators may be such as a whining type indicator and a releasing type indicator.

  The first output unit of the camera body outputs a first image signal for displaying a first image corresponding to the image according to the captured image signal and supplies the first image signal to one of the two displays. In addition, a second output unit of the camera body outputs a second image signal for displaying a second image having information that becomes effective when imaging, and is supplied to the other of the two displays. .

  For example, the camera body is a second output when the two displays are a peep type display and a release type display and the second image is a magnified image corresponding to a portion of the first image The second image signal output from the unit may be supplied to a viewing type display. Also, for example, in the camera body, the two displays are the display of the peeping type and the display of the release type, and the second image corresponds to the predetermined brightness level range of the captured image signal in the first image. The second image signal output from the second output unit may be supplied to the release type display when the image is an image showing the area in a predetermined color or specific luminance pattern.

  As described above, in the present technology, the first image signal for displaying the first image corresponding to the image by the captured image signal is output from the camera body, supplied to one of the two displays, and imaged. A second image signal for displaying a second image having information that is effective at the time is output and supplied to the other of the two displays. Therefore, it becomes possible to display information that is effective when imaging, without affecting the confirmation display of the imaging main line signal.

Hereinafter, modes for carrying out the invention (hereinafter referred to as “embodiments”) will be described. The description will be made in the following order.
1. Embodiment 2. Modified example

<1. Embodiment>
[Configuration Example of Camera Device]
FIG. 1 shows a configuration example of a camera device 10 as an embodiment. The camera device 10 includes a camera body 100, an imaging lens 200, and two displays 301 and 302. The imaging lens 200 is attached to a lens mount (not shown) in the front of the camera body 100. The two displays 301 and 302 are attached to the camera body 100 so that the user (photographer) can monitor them simultaneously. The displays 301 and 302 are, for example, open type displays configured by liquid crystal panels.

  From the camera body 100, a captured image signal is output as a main line signal. This main line signal is sent to a camera control unit (CCU) not shown. Further, a return signal is input to the camera body 100 from the camera control unit. The main line signal may be sent to the recording apparatus.

  The camera body 100 outputs a first image signal for displaying a first image corresponding to an image based on a captured image signal and supplies the first image signal to the display 301. Then, the display 301 displays a first image based on the first image signal. The user (photographer) can always check the image pickup main line signal based on the display image (first image) of the display 301.

  In addition, the camera body 100 outputs a second image signal for displaying a second image having information that becomes effective when imaging, and supplies the second image signal to the display 302. Then, the display 302 displays a second image based on the second image signal. The user (photographer) can obtain information that is effective when imaging based on the display image (first image) of the display 302.

  The first image signal and the second image signal output from the camera body 100 are generated in the camera body 100 or sent as a return signal from the camera control unit.

  For example, the display 302 displays, for example, a magnified image corresponding to a part of the first image as the second image. In this case, the user (photographer) sets the second image to include the focus point, and precisely performs the focus adjustment (focusing) of the focus point based on the second image. Is possible.

  Further, for example, the display 302 displays, as the second image, an image showing a region corresponding to a predetermined luminance level range of the captured image signal in the first image in a predetermined color or a specific luminance pattern. . In this case, the user (photographer) can easily adjust the luminance level of the predetermined area of the image to fall within the predetermined luminance level range based on the second image.

  Also, for example, the display 302 displays an image including information indicating an imaging state as a second image. For example, the information indicating the imaging state is information such as a lens state and a camera setting state, more specifically, a frame rate, a shutter opening angle, and the like. In this case, the user (photographer) can easily grasp the imaging state based on the second image.

  Also, for example, the display 302 displays an on-air image as a second image. In this case, the second image signal is an image signal sent from the camera control unit. In this case, the user (photographer) can confirm the on-air image based on the second image.

  In addition, for example, the display 302 displays, as the second image, an image including a display (marker) indicating a focusing position on the first image or the enlarged image corresponding to a part of the first image. Do. In this case, the second image signal is an image signal sent from the camera control unit. In this case, the user (photographer) can easily grasp the indication of the focusing position from the camera control unit side based on the second image.

  FIG. 2 shows an example of the internal module configuration of the camera body 100. The camera body 100 includes a control unit 101, a user operation unit 102, an imaging unit 103, a signal processing unit 104, a standard processing unit 105, an enlargement processing unit 106, a level display processing unit 107, and a status generation module 108. have. The camera body 100 further includes a first selector 109, an output module 110, a second selector 111, an output module 112, and a return separation processor 113.

  A control unit (camera CPU) 101 controls the operation of each unit of the camera body 100. The user operation unit 102 is connected to the control unit 101, and configures a user interface for the user to perform various operations.

  The imaging unit 103 includes an image sensor such as a complementary metal-oxide semiconductor (CMOS) or a charge coupled device (CCD), and outputs a captured image signal such as an HD resolution or 4K resolution. A subject is imaged on the imaging surface of the image sensor by the imaging lens 200 described above. The signal processing unit 104 performs processing such as defect correction processing on the captured image signal output from the imaging unit 103, and outputs a captured image signal (main line signal) as an output of the camera body 100. The captured image signal is sent to a camera control unit (not shown).

  The standard processing unit 105 processes the captured image signal output from the signal processing unit 104, and corresponds to the image by the captured image signal, for displaying a first image of the same image frame as the captured image signal. A first image signal of resolution is obtained. For example, when the captured image signal is in the form of RAW in which the RGB different arrangement (Bayer arrangement) is output as it is, the standard processing unit 105 converts the same into the arrangement RGB signal. Further, when the captured image signal is a high resolution image signal such as 4K resolution, the standard processing unit 105 performs down conversion.

  The enlargement processing unit 106 processes the captured image signal output from the signal processing unit 104 to have a second HD resolution for displaying an enlarged image corresponding to a part of the first image as a second image. Obtain an image signal. For example, when the captured image signal is an image signal of HD resolution, the enlargement processing unit 106 cuts out a part and up-converts. Also, for example, when the captured image signal is an image signal with 4K resolution or other high resolution, the enlargement processing unit 106 cuts out a part corresponding to the HD resolution and uses it as it is. In this case, there is no reduction in resolution as in the case of upconversion processing.

  In this case, the user (photographer) can arbitrarily set the cutout position, that is, the position to be enlarged, by the user operation unit 102. The user (photographer) can perform the focus adjustment (focusing) of the focus point with high accuracy based on the enlarged image by setting the cutout position so as to include the focus point, for example.

  The level display processing unit 107 processes the captured image signal output from the signal processing unit 104, and specifies in advance a color or an area corresponding to a predetermined luminance level range of the captured image signal in the first image. A second image signal is obtained to display an image represented by a luminance pattern (for example, a zebra pattern, a cross hatch pattern, etc.) as a second image. In this case, the user (photographer) can arbitrarily set the luminance level range and the color or luminance pattern by the user operation unit 102.

  The status generation module 108 obtains a second image signal for displaying an image including information indicating an imaging state (lens state, camera setting state, etc.) as a second image. The second image is, for example, an image in which information indicating an imaging state is displayed in characters.

  The return separation processing unit 113 receives a return signal sent from the camera control unit. The return separation processing unit 113 separates and acquires the first image signal and / or the second image signal included in the return signal. The first image signal separately acquired from the return signal is an image for displaying the first image corresponding to the image by the captured image signal, similarly to the first image signal obtained by the standard processing unit 105 described above. It is a signal. The first image signal is obtained by performing processing equivalent to that of the standard processing unit 105 on a captured image signal sent from the camera body 100 as a main line signal on the camera control unit side.

  In addition, the second image signal separately acquired from the return signal is picked up in the same manner as the second image signal obtained by the enlargement processing unit 106, the level display processing unit 107, the status generation module 108, etc. It is an image signal for displaying a second image having valid information. The second image signal is obtained on the camera control unit side, for example, based on a captured image signal sent from the camera body 100 as a main line signal.

  For example, the second image signal thus separately acquired from the return signal is an image signal for displaying the on-air image as a second image. Also, for example, in the second image signal thus acquired separately from the return signal, a display (marker) indicating the position of focusing on the enlarged image corresponding to the first image or a part of the first image is displayed. It is an image signal for displaying an included image or an enlarged image indicating a position of focusing as a second image. Further, for example, the second image signal thus separately acquired from the return signal is an image signal for displaying an image including information indicating an imaging state as a second image.

  The first selector 109 selectively extracts the first image signal obtained by the standard processing unit 105 or the first image signal obtained by the return separation processing unit 113, and supplies the signal to the output module 110. The output module 110 converts the first image signal supplied from the first selector 109 into a signal of a signal format compatible with the digital interface to which the display 301 is applied, for example, an SDI signal, and transmits the signal to the display 301. Do.

  The second selector 111 separates the second image signal obtained by the enlargement processing unit 106, the second image signal obtained by the level display processing unit 107, the second image signal obtained by the status generation module 108, or return separation processing. The second image signal obtained by the unit 113 is selectively taken out and output to the output module 112. The output module 112 converts the second image signal supplied from the second selector 111 into a signal of a signal format compatible with the digital interface to which the display 302 is applied, for example, an SDI signal, and outputs the signal to the display 302. Do.

  Signal selection in the first selector 109 and the second selector 111 is controlled by the control unit 101. In this case, when there is a selector control signal from the camera control unit, control is performed based on the control signal.

  The flowchart in FIG. 3 illustrates an example of switching control processing of the first selector 109 and the second selector 111 in the control unit 101. The control unit 101 starts control processing in step ST1, and then proceeds to processing of step ST2.

  In step ST2, the control unit 101 determines whether the first display return signal is input, that is, whether the first image signal is included in the return signal. When the first image signal is included in the return signal, the control unit 101 proceeds to the process of step ST3. On the other hand, when the first image signal is not included in the return signal, the control unit 101 switches the selector 1 to the standard processing signal in step ST4, that is, the first processing unit 105 obtains the first selector 109. Switching so as to take out the first image signal to be output. Thereafter, the control unit 101 proceeds to the process of step ST3.

  In step ST3, the control unit 101 determines whether a return signal for the second display is input, that is, whether the return signal includes the second image signal. When the second image signal is included in the return signal, the control unit 101 proceeds to the process of step ST5. On the other hand, when the second image signal is not included in the return signal, the control unit 101 switches the selector 2 according to the main body selection instruction menu in step ST6, that is, the main body selection instruction menu indicates the second selector 111. It switches so that 2nd image signal may be taken out. Thereafter, the control unit 101 proceeds to the process of step ST5.

  In step ST5, the control unit 101 determines whether the first external control signal for the display is input from the camera control unit to the camera body 100. When the external control signal for the first display is input, the control unit 101 switches the selector 1 in accordance with the external control instruction in step ST7, that is, the first control signal indicates the first selector 109. Switch to take out the image signal of. Thereafter, the control unit 101 proceeds to the process of step ST8.

  On the other hand, when the external control signal for the first display is not input in step ST5, the control unit 101 switches the selector 1 to the standard processing signal in step ST9, that is, the first selector 109 performs the standard processing. It switches so that the 1st image signal obtained by the part 105 may be taken out. Thereafter, the control unit 101 proceeds to the process of step ST8.

  In step ST8, the control unit 101 determines whether or not the external control signal for the second display is input from the camera control unit to the camera body 100. When the external control signal for the second display is input, the control unit 101 switches the selector 2 in accordance with the external control instruction in step ST10, that is, the second control signal indicates the second selector 111. Switch to take out the image signal of.

  On the other hand, when the external control signal for the first display is not input in step ST8, the control unit 101 proceeds to the process of step ST11. In step ST11, the control unit 101 switches the selector 2 in accordance with the main body selection instruction menu, that is, switches the second selector 111 so as to take out the second image signal indicated by the main body selection instruction menu.

  The operation of the camera body 100 shown in FIG. 2 will be briefly described. The image signal output from the imaging unit 103 is supplied to the signal processing unit 104 and subjected to processing such as defect correction processing. The captured image signal obtained by the signal processing unit 104 is output from the camera body 100 as a main line signal, and is sent to, for example, a camera control unit.

  Further, the captured image signal obtained by the signal processing unit 104 is supplied to the standard processing unit 105, the enlargement processing unit 106, and the level display processing unit 107. In the standard processing unit 105, the captured image signal is processed, and the first image signal of HD resolution for displaying the first image of the same image frame as the captured image signal corresponding to the image by the captured image signal Is obtained. This first image signal is supplied to the first selector 109.

  In addition, the enlargement processing unit 106 processes the captured image signal output from the signal processing unit 104, and displays the enlarged image corresponding to a part of the first image as the second image. An image signal of 2 is obtained. This second image signal is supplied to the second selector 111.

  Further, the level display processing unit 107 processes the captured image signal output from the signal processing unit 104 and colors an area in the first image corresponding to a predetermined luminance level range of the captured image signal in advance. Alternatively, a second image signal for displaying the image indicated by the specific luminance pattern as a second image is obtained. This second image signal is supplied to the second selector 111.

  In the status generation module 108, a second image signal for displaying an image including information indicating an imaging state (a lens state, a camera setting state, etc.) as a second image is obtained. This second image signal is supplied to the second selector 111.

The second image signal obtained by the unit 113 is selectively extracted and supplied to the output module 112. In the output module 112, the second image signal is converted into a signal (for example, an SDI signal or the like) of a predetermined signal format corresponding to the display 302, and is supplied to the display 302. As a result, on the display 302, a second image capture including information indicating an imaging state by the second image signal extracted by the second selector 111 is displayed.

  In FIG. 4, either the second image signal from the enlargement processing unit 106 in the second selector 111, the second image signal from the level display processing unit 107, or the second image signal from the status generation module 108 is selected.
