Description

The present invention relates to a parameter recording control device , a display device, a control method for the parameter recording control device , and a program .

  The production process of image content such as movie content and broadcast content generally includes a shooting process for generating image data (captured image data) by shooting and an editing process for editing the shot image data. It is. In recent years, image quality adjustment processing (color adjustment processing, color grading, etc.) using photographed image data is performed at the shooting site (shooting process site), and it may be confirmed in advance whether desired shooting is being performed. It is increasing.

  Conventionally, image quality adjustment processing (simple image quality adjustment processing) performed at the shooting site has been performed using a personal computer (PC). However, in recent years, using the display device having the image quality adjustment function for image quality adjustment processing described above, the captured image data is displayed on the display device without using a device such as a PC, and the image quality adjustment processing using the captured image data is performed. Has come to be done.

  The image quality adjustment parameters used in the image quality adjustment process performed at the shooting site are recorded in the storage unit and used in the image quality adjustment process (detailed image quality adjustment process) performed in the editing process.

  However, conventionally, it has been necessary to manually record image quality adjustment parameters in the storage unit. Conventionally, when reproducing captured image data, it is necessary to manually read out the image quality adjustment parameters from the storage unit and set them in the image quality adjustment unit (functional unit for executing image quality adjustment processing). In general, the image quality adjustment parameter differs for each scene of the image content. Therefore, conventionally, it is necessary to record image quality adjustment parameters, read image quality adjustment parameters, set image quality adjustment parameters, and the like for each scene. As described above, conventionally, complicated user operations for recording image quality adjustment parameters, reading image quality adjustment parameters, setting image quality adjustment parameters, and the like are necessary, and the burden on the user is large. In the past, when reproducing captured image data, it was necessary to perform a difficult and heavy work (user work) of selecting an image quality adjustment parameter corresponding to a scene to be reproduced from a large amount of image quality adjustment parameters. .

  Also, an appropriate management method for image quality adjustment parameters depends on the work content. For example, in the operation of checking the captured image data on the display device without recording, user operations for recording image quality adjustment parameters, reading image quality adjustment parameters, setting image quality adjustment parameters, and the like are not required. In the operation of recording the captured image data, a user operation for recording the image quality adjustment parameter is required in order to use the image quality adjustment parameter used in the operation in a subsequent process. In the operation of reproducing and checking the recorded captured image data, a user operation for reading and setting image quality adjustment parameters is necessary to reproduce the image quality adjustment processing performed in the previous process. In addition, when a user operation for changing the set image quality adjustment parameter is performed in the operation of reproducing and checking the recorded captured image data, a user operation for recording the changed image quality adjustment parameter is necessary. It is. Therefore, conventionally, it has been necessary for the user to determine and execute an appropriate user operation according to the work content.

A conventional technique for reducing the burden on the user is disclosed in Patent Document 1, for example. In the technique disclosed in Patent Document 1, the genre of the program to be reproduced is acquired, and the operations of the television and the amplifier are controlled according to the audio output mode corresponding to the acquired genre. However, the technique disclosed in Patent Document 1 is a technique for omitting a user operation for switching an audio output device, and is not a technique related to an image quality adjustment parameter management method. For this reason, even when the technique disclosed in Patent Document 1 is used, the above-described burden when appropriately managing (recording or setting) image quality adjustment parameters cannot be reduced.

  FIG. 1A is a block diagram illustrating an example of a configuration of an image editing system according to the present embodiment. As shown in FIG. 1A, the image editing system according to the present embodiment includes a photographing apparatus 101, a recording / reproducing apparatus 102, and a display apparatus 103. The photographing apparatus 101 and the recording / reproducing apparatus 102 are directly connected to each other using an SDI (Serial Digital Interface) cable. The recording / reproducing device 102 and the display device 103 are also directly connected to each other using an SDI cable. For the display device 103, the photographing device 101 and the recording / reproducing device 102 are external devices.

Note that the cable connecting the photographing apparatus 101 and the recording / reproducing apparatus 102 and the cable connecting the recording / reproducing apparatus 102 and the display apparatus 103 are not limited to SDI cables. Any cable may be used as long as it can transmit image data, audio data, control data, and the like. For example, an HDMI cable that can transmit control data bidirectionally may be used. . In that case, image data and audio data are transmitted through a TMDS line defined by the HDMI standard, and control data is transmitted by a CEC line or DDC line defined by the HDMI standard. Further, the cable connecting the image capturing apparatus 101 and the recording / reproducing apparatus 102 may be a cable different from the cable connecting the recording / reproducing apparatus 102 and the display apparatus 103. The photographing apparatus 101 and the recording / reproducing apparatus 102 may be connected wirelessly, or the recording / reproducing apparatus 102 and the display apparatus 103 may be connected wirelessly.
In this embodiment, an example in which the image data is moving image data will be described, but the image data may be still image data.

  The photographing apparatus 101 generates image data (photographed image data) by photographing and outputs the generated image data. As the photographing apparatus 101, for example, various digital cameras can be used.

The recording / reproducing apparatus 102 acquires the image data output from the imaging apparatus 101 and outputs the image data and control data. The recording / reproducing apparatus 102 includes a storage unit, and executes a recording process for recording image data acquired from the photographing apparatus 101 in the storage unit, a reproducing process for reproducing image data recorded by the recording process, and the like. Can do. When the image data is moving image data, in the reproduction process, each frame of the moving image data recorded in the storage unit is reproduced in order. The recording / reproducing apparatus 102 outputs the image data acquired from the photographing apparatus 101 as it is, or outputs the image data reproduced by the reproduction process. In the present embodiment, the control data includes state information indicating the operation state of the recording / reproducing device 102. In the present embodiment, the state information includes first state information related to recording processing and second state information related to reproduction processing and pause processing. For example, the status information indicates whether a recording process is being performed, whether a reproduction process is being performed, whether a pause process is being performed, or the like. The pause process is a process that does not update a frame to be played back (target for playback process). In this embodiment, the control data includes the data name of the image data to be recorded or reproduced, the time code of the frame to be recorded or reproduced, and the like. The time code is time position information indicating the time position of the frame in the moving image data. As the recording / reproducing apparatus 102, various recorders can be used.

  Note that an image recording device that performs recording processing and an image playback device that performs playback processing and pause processing may be used instead of the recording / playback device 102 that performs recording processing, playback processing, and pause processing. Good. When the image recording apparatus and the image reproducing apparatus are used, the first state information can be said to be “information indicating the operating state of the image recording apparatus”, and the second state information is “the operating state of the image reproducing apparatus”. You can say “information”.

  The display device 103 acquires the image data and control data output from the recording / reproducing device 102. Then, the display device 103 performs predetermined image processing on the acquired image data, and displays an image based on the image data after the predetermined image processing is performed. The predetermined image processing includes image quality adjustment processing for adjusting the image quality (color, brightness, etc.) of the image data using the image quality adjustment parameter set for the display device 103. As the predetermined image processing, only image quality adjustment processing may be performed, or a plurality of image processing including image quality adjustment processing may be performed. As the display device 103, a liquid crystal display device, an organic EL display device, a plasma display device, or the like can be used.

  As an image color management method, there is ASC CDL (The American Society of Cinematographers Color Decision List) proposed by the American Film Directors Association. Hereinafter, ASC CDL is simply referred to as “CDL”. The type of image quality adjustment parameter used in the present embodiment is not particularly limited. For example, an image quality adjustment parameter of a type defined by CDL can be used as the image quality adjustment parameter.

  In CDL, SLOPE, OFFSET, POWER, and SATURATION are defined as types of image quality adjustment parameters. The image quality adjustment parameter of SLOPE is a gain value that is multiplied by each gradation value of image data. The OFFSET image quality adjustment parameter is an offset value to be added to or subtracted from each gradation value of the image data. The POWER image quality adjustment parameter is a gamma value of gamma conversion processing applied to image data. The image quality adjustment parameter of SATURATION is a chroma gain value that is multiplied by each chroma value of the image data.

  If an image quality adjustment parameter of a type defined by CDL is used, an image quality adjustment parameter set at the time of color editing using a certain display device is set in another display device. The display color (color on the screen) can be matched.

  FIG. 2A is a block diagram illustrating an example of the configuration of the recording / reproducing device 102 and the display device 103. As shown in FIG. 2A, the recording / reproducing apparatus 102 includes an input unit 201, an output unit 202, a control unit 203, and a storage unit 204. The display device 103 includes an input unit 210, an image processing unit 211, a display unit 212, a control unit 213, and an I / F unit 214.

First, the configuration of the recording / reproducing apparatus 102 will be described.
The input unit 201 acquires image data from the photographing apparatus 101.
The output unit 202 outputs image data and control data to the display device 103.
The storage unit 204 is a first storage device that stores image data acquired from the photographing apparatus 101. As the first storage device, an optical disk, a magnetic disk, a semiconductor memory, or the like can be used. The first storage device may be a storage device that can be attached to and detached from the recording / reproducing device 102, or may be a storage device that cannot be attached to or detached from the recording / reproducing device 102.
The control unit 203 generates control data or controls the operation of each functional unit included in the recording / reproducing device 102 in response to a user operation on the recording / reproducing device 102.

  When a user operation for instructing execution of the recording process is performed on the recording / reproducing apparatus 102, status information indicating that the recording process is being performed, the data name of the image data to be recorded, and the frame to be recorded The control data including the time code, etc. is generated. Then, the image data acquired by the input unit 201 is recorded in the storage unit 204, and the image data acquired by the input unit 201 and the control data are output from the output unit 202. Therefore, during the execution of the recording process, the image data to be recorded (recorded image data) is displayed after being subjected to the image quality adjustment process, and the recorded image data before the image quality adjustment process is recorded.

  When a user operation instructing execution of the reproduction process is performed on the recording / reproducing apparatus 102, status information indicating that the reproduction process is being performed, the data name of the image data to be reproduced, and the frame to be reproduced The control data including the time code, etc. is generated. Then, image data to be reproduced is read from the storage unit 204 to the output unit 202, and the image data read from the storage unit 204 and the control data are output from the output unit 202. Therefore, during the reproduction process, the image data to be reproduced (reproduced image data) is subjected to the image quality adjustment process and displayed.

  In a period in which neither recording processing nor playback processing is performed, the image data acquired by the input unit 201 is output from the output unit 202.

  Next, the configuration of the display device 103 will be described.

  The input unit 210 acquires image data and control data from the recording / playback apparatus 102, outputs the acquired image data to the image processing unit 211, and outputs the acquired control data to the control unit 213. When the recording process is performed, the image data to be recorded is acquired, and when the reproduction process is performed, the image data to be reproduced (image data of the frame to be reproduced) is acquired.

  Note that the process of acquiring image data and the process of acquiring control data may be realized by different functional units. In addition, when the first state information and the second state information are acquired separately, a process for acquiring the first state information (first acquisition process) and a process for acquiring the second state information (second acquisition process) ) May be realized by different functional units.

  The image processing unit 211 performs predetermined image processing on the image data output from the input unit 210. In this embodiment, the image data output from the input unit 210 is subjected to image quality adjustment processing using image quality adjustment parameters set for the image processing unit 211. The image processing unit 211 outputs the image data after the image quality adjustment processing to the display unit 212. When the image processing unit 211 executes only the image quality adjustment process, the image processing unit 211 can also be referred to as an “image quality adjustment unit”.

  The display unit 212 displays an image based on the image data output from the image processing unit 211 (image data after image quality adjustment processing is performed). As the display unit 212, a liquid crystal display panel, an organic EL display panel, a plasma display panel, or the like can be used.

  The I / F unit 214 is used for communication with the external storage 215. In this embodiment, the I / F unit 214 is used when recording image quality adjustment parameters in the external storage 215 and reading image quality adjustment parameters from the external storage 215.

  The external storage 215 is a second storage device that can store image quality adjustment parameters. As the second storage device, a storage medium such as an optical disk, a magnetic disk, or a semiconductor memory can be used. In this embodiment, a USB memory that can be attached to and detached from the display device 103 is used as the external storage 215. Note that the second storage device may be a storage device that is detachable from the display device 103, or may be a storage device that is detachable from the display device 103. One storage device that serves as both the first storage device and the second storage device may be used.

  The control unit 213 performs parameter setting processing, detection processing, parameter recording processing, and the like based on control data output from the input unit 210, user operation on the display device 103, and the like. The parameter setting process is a process for setting image quality adjustment parameters for the image processing unit 211. For example, in the parameter setting process, the image quality adjustment parameter is set according to the user operation, the image quality adjustment parameter is read from the external storage 215 and set, or the set image quality adjustment parameter is changed according to the user operation. Or The detection process is a process for detecting the start of the recording process, the start of the reproduction process, and the like. In the present embodiment, the operating state of the recording / reproducing apparatus 102 is determined based on the state information included in the control data. Then, by monitoring the status information included in the control data, the start of the recording process, the start of the reproduction process, and the like are detected. The parameter recording process is a process for recording the image quality adjustment parameter in the external storage 215. Note that at least one of the parameter setting process, the detection process, and the parameter recording process may be executed by a functional unit different from the control unit 213.

  Note that the parameter recording control apparatus according to the present embodiment only needs to have a configuration capable of executing at least the detection process and the parameter recording process. The display unit 212 and the image processing unit 211 may be provided in a device different from the parameter recording control device according to the present embodiment. The parameter setting process may be performed by an apparatus different from the parameter recording control apparatus according to the present embodiment. The parameter recording control device according to this embodiment includes a recording / reproducing device 102, an image recording device (image recording unit), an image reproducing device (image reproducing unit), a first storage device, a second storage device, and the like. Also good.

  Further, as shown in FIG. 2B, a configuration in which the storage unit 204 of the photographing apparatus 101 is used instead of the external storage 215 may be used. In this case, the I / F unit 214 is used for communication with the storage unit 204 of the imaging apparatus 101 and is used when recording image quality adjustment parameters in the storage unit 204 of the imaging apparatus 101. The I / F unit 214 and the storage unit 204 of the photographing apparatus 101 may be configured to perform wireless communication or may be configured to communicate via an HDMI cable or the like.

  FIG. 3 is a flowchart illustrating an example of the operation of the display device 103. The flowchart in FIG. 3 is started, for example, when a change in the operation state of the recording / reproducing apparatus 102 is detected by the control unit 213 as a trigger. A change in the operating state of the recording / reproducing apparatus 102 can be detected by monitoring the state information.

  First, in S301, the control unit 213 determines whether or not the recording process has been started based on the state information (first state information) included in the control data acquired by the input unit 210. By this process, the start of the recording process is detected. If it is determined that the recording process has been started, the process proceeds to S302. If it is determined that the recording process has not been started, the process proceeds to S303.

In step S <b> 302, the control unit 213 uses the external storage 215 as the image quality adjustment parameter set for the image processing unit 211 at the start of the recording process as the image quality adjustment parameter corresponding to the image data to be started. Record automatically. In this embodiment, the image quality adjustment parameter set at the start of the recording process is recorded as the image quality adjustment parameter corresponding to all frames of the moving image data to be recorded. For example, the control unit 213 records the image quality adjustment parameter in the external storage 215 in association with association information indicating image data corresponding to the image quality adjustment parameter. As the correspondence information, information including the data name of the image data can be used. By describing the correspondence information in at least one of the file name and tag of the data file for the image quality adjustment parameter, the correspondence information can be associated with the image quality adjustment parameter. The correspondence information can also be associated with the image quality adjustment parameter by separately describing the correspondence information in the file name and tag of the data file of the image quality adjustment parameter. The association method is not particularly limited.

  Note that the timing of the process of S302 is not particularly limited. For example, the process of S302 may be performed at the start of the recording process, may be performed during the execution of the recording process, or may be performed at the end of the recording process. When the process of S302 is performed at the start of the recording process, the start of the recording process may be detected. When the process of S302 is performed at the end of the recording process, the start and end of the recording process may be detected.

  In S303, the control unit 213 determines whether or not the reproduction process is started based on the state information (second state information) included in the control data acquired by the input unit 210. By this process, the start of the reproduction process is detected. If it is determined that the reproduction process has been started, the process proceeds to S304. If it is determined that the reproduction process has not been started, this flowchart ends.

  In step S <b> 304, the control unit 213 automatically reads out the image quality adjustment parameter stored in the external storage 215 from the external storage 215 as the image quality adjustment parameter corresponding to the started image data to be reproduced. Then, the control unit 213 automatically sets the read image quality adjustment parameter for the image processing unit 211. The correspondence between the image quality adjustment parameter and the image data can be confirmed by referring to the correspondence information associated with the image quality adjustment parameter, for example. The process of S304 is preferably performed at the start of the reproduction process.

According to the flowchart of FIG. 3, the image quality adjustment parameter corresponding to the image data to be recorded is automatically recorded in the external storage 215 only by the user performing an operation to instruct execution (start) of the recording process. Further, the image quality adjustment parameter corresponding to the image data to be reproduced is automatically read out from the external storage 215 and the image processing unit 211 is read out only by the user performing an operation to instruct execution (start) of the reproduction process. Automatically set. Thereby, a user's load can be reduced significantly. Further, during the reproduction process, the result of the image quality adjustment process performed in the past can be easily reproduced.
During playback processing, the recording / playback apparatus 102 automatically reads out the image quality adjustment parameter corresponding to the image data to be played back from the external storage 215 and automatically sends it to an image processing unit (not shown) inside the recording / playback apparatus 102. The configuration may be set.

  FIG. 4 is a flowchart illustrating an example of the operation of the display device 103 when a user operation (parameter changing operation) for changing the image quality adjustment parameter set for the image processing unit 211 is performed. The flowchart in FIG. 4 is started, for example, when a parameter change operation is detected by the control unit 213 as a trigger.

First, in S401, the control unit 213 determines whether or not a recording process is being performed based on the state information (first state information) included in the control data acquired by the input unit 210. By this process, a parameter change operation performed during the execution of the recording process is detected. If it is determined that the recording process is being performed, the process proceeds to S402. If it is determined that the recording process is not being performed, the process proceeds to S403.

  In step S <b> 402, the control unit 213 automatically records the image quality adjustment parameter after the change according to the parameter change operation in the external storage 215 as the image quality adjustment parameter corresponding to the image data that is currently being recorded. In the present embodiment, the changed image quality adjustment parameter is recorded as the image quality adjustment parameter corresponding to all frames of the moving image data to be recorded. As described above, in this embodiment, when a parameter change operation performed during the execution of the recording process is detected, the image quality adjustment parameter after the change according to the parameter change operation corresponds to the image data to be recorded. Automatically recorded as image quality adjustment parameters.

  In S403, the control unit 213 determines whether or not a reproduction process is being performed based on the state information (second state information) included in the control data acquired by the input unit 210. By this process, a parameter change operation performed during the execution of the reproduction process is detected. If it is determined that the reproduction process is being performed, the process proceeds to S404. If it is determined that the reproduction process is not being performed, this flowchart is terminated.

  In S <b> 404, the control unit 213 determines whether or not a suspension process is being performed based on the state information (second state information) included in the control data acquired by the input unit 210. By this process, a parameter change operation performed during the non-pause reproduction period (first period) and a parameter change operation performed during the pause reproduction period (second period) are detected. The non-pause reproduction period is a period during which the reproduction process is being executed, and is a period other than the period during which the pause process is being executed. The pause reproduction period is a period during which the reproduction process is being executed, and is a period during which the pause process is being executed. If it is determined that the pause process has not been performed, the process proceeds to S405. If it is determined that the pause process has been performed, the process proceeds to S406.

  In S405 and S406, the control unit 213 automatically records the image quality adjustment parameter after the change according to the parameter change operation in the external storage 215 as the image quality adjustment parameter corresponding to the image data that is currently being reproduced. To do. As described above, in this embodiment, when a parameter change operation performed during the execution of the reproduction process is detected, the image quality adjustment parameter after the change according to the parameter change operation corresponds to the image data to be reproduced. Automatically recorded as image quality adjustment parameters.

  Specifically, in S405, the image quality adjustment parameter after the change according to the parameter change operation is automatically recorded as the image quality adjustment parameter corresponding to all frames of the moving image data to be reproduced. As described above, in this embodiment, when a parameter change operation performed during the non-pause playback period is detected, the image quality adjustment parameter after the change according to the parameter change operation is set to the moving image data to be played back. Automatically recorded as image quality adjustment parameters corresponding to all frames.

  In S406, the image quality adjustment parameter after the change according to the parameter changing operation is recorded as the image quality adjustment parameter corresponding to the frames subsequent to the reproduction target frame among the frames of the moving image data to be reproduced. As described above, in this embodiment, when a parameter change operation performed during the pause playback period is detected, the image quality adjustment parameter after the change according to the parameter change operation is added to the frames subsequent to the playback target frame. It is automatically recorded as the corresponding image quality adjustment parameter. In S406, for example, image quality adjustment parameters corresponding to some frames of the moving image data are recorded in the external storage 215 in association with correspondence information indicating the some frames. As the correspondence information, information including the data name of the moving image data and the time code of some frames can be used.

  According to the flowchart of FIG. 4, the image quality adjustment parameter after the change is automatically recorded as the image quality adjustment parameter corresponding to the image data to be recorded only by the user performing the parameter changing operation during the execution of the recording process. Further, the image quality adjustment parameter after the change is automatically recorded as the image quality adjustment parameter corresponding to the image data to be reproduced simply by performing the parameter changing operation during execution of the reproduction process by the user. Thereby, a user's load can be reduced significantly.

  Note that the process of S402 may be a process of updating the image quality adjustment parameter recorded in the external storage 215 (overwrite storage), or a process of additionally recording a new image quality adjustment parameter in the external storage 215. Good. The process in S405 and the process in S406 are the same. If overwriting is performed as the process of S402, the process of S405, and the process of S406, a user operation for selecting an image quality adjustment parameter to be set in the image processing unit 211 from a plurality of image quality adjustment parameters becomes unnecessary. The load can be further reduced.

  FIG. 5 is a diagram illustrating an example of image data recorded in the storage unit 204 of the recording / playback apparatus 102 and image quality adjustment parameters recorded in the external storage 215. In the example of FIG. 5, moving image data having a data name “scene1” is recorded in the storage unit 204 as moving image data of the scene (shooting scene) 1 of the image content to be created. Then, moving image data having a data name “scene2” is recorded as moving image data of the scene 2. In the example of FIG. 5, “dpx” is used as the extension of the image data.

  According to the present embodiment, the image quality adjustment parameter corresponding to the image data can be automatically recorded in the external storage 215. In FIG. 5, the data file “scene1.cdl” is a data file of image quality adjustment parameters corresponding to the moving image data of the scene 1. The data file “scene2.cdl” is a data file of image quality adjustment parameters corresponding to the moving image data of the scene 2. As described above, the image quality adjustment parameter can be associated with the image data by including the data name of the image data in the file name of the data file of the image quality adjustment parameter.

  Further, according to the present embodiment, image quality adjustment parameters corresponding to some frames of moving image data can be automatically recorded in the external storage 215. In FIG. 5, the data file “scene2 — 00010000.cdl” is a data file of image quality adjustment parameters corresponding to frames after the frame of the time code “00: 01: 00.00” among the frames of the moving image data of the scene 2. is there. Thus, by including the data name of the image data and the time code in the file name of the data file of the image quality adjustment parameter, the image quality adjustment parameter can be associated with a part of the frames of the moving image data.
