Description

The present technology relates to an imaging system and an image display method.

As a display of image pickup information in a camera device, for example, there is a display of a lens focus state. Conventionally, as a display method thereof, it is known to emphasize and display a high frequency component of a captured image. Alternatively, as a display method thereof, it is known that an arbitrary necessary area is enlarged and scaled to inform the photographer of the focal state of the lens. However, in the case of these display methods, since the display is switched from the image pickup main line signal on one display, the true state of the image pickup main line signal cannot always be confirmed. Further, conventionally, a method of combining a main line image and an enlarged image and displaying them on one screen has been proposed (see, for example, Patent Document 1). However, in this case, it is displayed in one screen, and the true main line image cannot be confirmed at the same time.

Further, as the display of the image pickup information in the camera device, for example, there is a display of the luminance level of the image pickup signal. Also in this display, the area of the level specified in advance is replaced with a color or a specific image for identification, but the image pickup main line cannot always be confirmed.

Further, as the display of the imaging information in the camera device, for example, there is the display of the status information at the time of imaging. Regarding this display, in the past, for example, the status information at the time of imaging is often superimposed as characters on the upper and lower parts of the display screen of the captured image, but the superimposed portion hides the image, which causes an obstacle to imaging. There was also.

In addition, in the case of a system in which an image of an arbitrary camera device is used as an on-air image using a plurality of camera devices, the on-air image can be transmitted to each camera device as a return image for confirmation. There is. Also in this case, there is only one display for displaying on the image pickup device side, it is necessary to switch the signal, and it is impossible to operate while checking the on-air image for a long time.

<1. Embodiment>
[Camera device configuration example]
FIG. 1 shows a configuration example of the camera device 10 as an embodiment. The camera device 10 includes a camera body 100, an image pickup lens 200, and two indicators 301 and 302. The image pickup lens 200 is attached to a lens mount portion (not shown) at the front portion of the camera body 100. The two indicators 301 and 302 are attached to the camera body 100 so that the user (cameraman) can monitor them at the same time. The indicators 301 and 302 are open type indicators configured by, for example, a liquid crystal panel.

The captured image signal is output as a main line signal from the camera body 100. 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 device.

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

Further, the camera body 100 outputs a second image signal for displaying a second image having information useful for imaging and supplies the second image signal to the display 302. Then, the display 302 displays the second image by the second image signal. The user (cameraman) can obtain information useful for taking an image 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, an enlarged image corresponding to a part of the first image as the second image. In this case, the user (cameraman) sets the second image to include the focus point, so that the focus adjustment (focusing) of the focus point can be performed accurately 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 with a predetermined color or a specific luminance pattern. .. In this case, the user (cameraman) can easily adjust the luminance level of the predetermined region of the image within the predetermined luminance level range based on the second image.

Further, 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 (cameraman) can easily grasp the image pickup state based on the second image.

Further, 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 (cameraman) can confirm the on-air image based on the second image.

Further, for example, the display 302 displays, as the second image, an image including a display (marker) indicating the focus location in the enlarged image corresponding to the first image or 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 (cameraman) can easily grasp the instruction of the focusing place from the camera control unit side based on the second image.

FIG. 2 shows an example of an internal module configuration of the camera body 100. The camera body 100 includes a control unit 101, a user operation unit 102, an image pickup 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. Further, the camera body 100 has a first selector 109, an output module 110, a second selector 111, an output module 112, and a return separation processing unit 113.

The 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 constitutes a user interface for the user to perform various operations.

The image pickup unit 103 has an image sensor such as CMOS (Complementary Metal-Oxide Semiconductor) and CCD (Charge Coupled Devices), and outputs an image pickup image signal such as HD resolution and 4K resolution. The image pickup lens 200 described above forms an image of a subject on the image pickup surface of the image sensor. 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 the captured image signal (main line signal) as the output of the camera body 100. This 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 displays the first image having the same image frame as the captured image signal, which corresponds to the image obtained by the captured image signal. Obtain the first image signal of resolution. For example, when the captured image signal is in the form of RAW that outputs an RGB heterogeneous arrangement (Bayer arrangement) as it is, the standard processing unit 105 converts it into an RGB signal having the same arrangement. Further, the standard processing unit 105 down-converts the captured image signal when it is a high-resolution image signal such as 4K resolution.

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. Get an image signal. For example, when the captured image signal is an HD resolution image signal, the enlargement processing unit 106 cuts out a part and up-converts it. Further, for example, when the captured image signal is a 4K resolution or other high resolution image signal, 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 performing up-conversion processing.

In this case, the user (cameraman) can arbitrarily set the cutout position, that is, the position to be enlarged by the user operation unit 102. By setting this cutout position to include, for example, the focus point, the user (cameraman) can accurately adjust the focus of the focus point (focusing) based on the enlarged image.

The level display processing unit 107 processes the captured image signal output from the signal processing unit 104 to specify a region corresponding to a predetermined luminance level range of the captured image signal in the first image with a predetermined color or specification. A second image signal for displaying an image represented by a luminance pattern (for example, a zebra pattern, a crosshatch pattern, etc.) as a second image is obtained. In this case, the user (cameraman) can arbitrarily set the luminance level range and the color or the 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. This second image is, for example, an image that displays information indicating an imaging state as characters.

The return separation processing unit 113 receives the 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 separated and acquired from the return signal is an image for displaying the first image corresponding to the image obtained by the captured image signal, similarly to the first image signal obtained by the standard processing unit 105 described above. It is a signal. This first image signal is obtained by subjecting the captured image signal transmitted from the camera body 100 as the main line signal on the camera control unit side to the same processing as that of the standard processing unit 105.

Further, the second image signal separated and acquired from the return signal is similar to the second image signal obtained by the enlargement processing unit 106, the level display processing unit 107, the status generation module 108, and the like described above, when imaging. It is an image signal for displaying a second image having valid information. This second image signal is obtained on the camera control unit side, for example, based on an image captured image signal transmitted as a main line signal from the camera body 100.

For example, the second image signal separated and acquired from the return signal in this way is an image signal for displaying the on-air image as the second image. Further, for example, the second image signal separated and acquired from the return signal has a display (marker) indicating the focus location on the enlarged image corresponding to the first image or a part of the first image. It is an image signal for displaying a included image or an enlarged image indicating a focus location as a second image. Further, for example, the second image signal separated and acquired from the return signal in this way is an image signal for displaying an image including information indicating an imaging state as a second image.

The first selector 109 selectively takes out 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 first image signal to the output module 110. The output module 110 converts the first image signal supplied from the first selector 109 into a signal in a signal format suitable for 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 is a second image signal obtained by the enlargement processing unit 106, a second image signal obtained by the level display processing unit 107, a second image signal obtained by the status generation module 108, or a return separation process. 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 in a signal format suitable for the digital interface to which the display 302 is applied, for example, an SDI signal, and outputs the signal to the display 302. do.

The 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, it is controlled based on the control signal.

The flowchart of FIG. 3 shows 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 the control process in step ST1, and then moves to the process of step ST2.

In this step ST2, the control unit 101 determines whether or not the return signal for the first display is input, that is, whether or not the return signal includes the first image signal. When the return signal includes the first image signal, the control unit 101 moves to the process of step ST3. On the other hand, when the return signal does not include the first image signal, the control unit 101 switches the selector 1 to the standard processing signal in step ST4, that is, the first selector 109 is obtained by the standard processing unit 105. It is switched so as to take out the first image signal to be obtained. After that, the control unit 101 moves to the process of step ST3.

In this step ST3, the control unit 101 determines whether or not the return signal for the second display is input, that is, whether or not the return signal includes the second image signal. When the return signal includes the second image signal, the control unit 101 moves to the process of step ST5. On the other hand, when the return signal does not include the second image 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. Switch to take out the second image signal. After that, the control unit 101 moves to the process of step ST5.

In this step ST5, the control unit 101 determines whether or not the external control signal for the first 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 according to the external control instruction in step ST7, that is, the first selector 109 is indicated by the external control signal. Switch to take out the image signal of. After that, the control unit 101 moves 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 is standard-processed. Switching is performed so that the first image signal obtained by the unit 105 is taken out. After that, the control unit 101 moves to the process of step ST8.

In this 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 according to the external control instruction in step ST10, that is, the second selector 111 is indicated by the external control signal. 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 shifts to the process of step ST11. In this step ST11, the control unit 101 switches the selector 2 according to 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.

In the camera body 100 shown in FIGS. 1 and 2, when the first image signal for displaying the first image corresponding to the image by the captured image signal is output and supplied to the display 301 and also imaged. A second image signal for displaying a second image having useful information is output and supplied to the display 301. Therefore, it is possible to display information that is effective at the time of imaging without affecting the confirmation display of the imaging main line signal.

For example, in the lens focus operation, it is easy to focus on a magnified image of a necessary area while confirming a natural whole image that is the main line, even if there are restrictions on the expression pixels on the display side. In addition, by using the return image generated by the camera control unit (external device), the focus area can be instructed smoothly.

Further, for example, in the iris operation of the lens, it is possible to simultaneously confirm and operate the luminance information of an arbitrary necessary area while confirming the natural whole image that becomes the main line. Further, for example, it is possible to constantly grasp various information of the image pickup apparatus in shooting while checking a natural image which is the main line.
