Case video processing apparatus, case video processing system, and case video processing method

1. A case video processing apparatus that performs image processing of a video data file including a first frame and a second subsequent frame and being related to a case, the case video processing apparatus comprising:

a processor; and

a memory,

wherein, in cooperation with the memory, the processor,

inputs the video data file to be processed,

detects a face region of a person included in an image of the first frame of the video data file,

registers the face region as a region to be masked,

inputs a user's instruction regarding the face region,

excludes a region designated by the user's instruction from targets to be masked and registers the region designated by the user's instruction as a region not to be masked,

registers a face characteristic of a target in the region not to be masked,

inputs a user's instruction which selects for masking an undetected face region of a person in the first frame of the video data file,

registers the undetected face region selected by the user's instruction as an additional target to be masked,

outputs video data having been subjected to image processing including excluding a region designated by the user's instruction from targets to be masked and masking the additional target,

detects a face region of a person included in an image of the second subsequent frame of the video data file,

identifies the region to be masked which is registered for the first frame of the video data file,

determines whether the detected face region of a person included in an image of the second subsequent frame of the video data file conforms to the registered face characteristic of a target in the region not to be masked,

includes, the detected face region of a person included in an image of the second subsequent frame of the video data file, in the targets to be masked, when the detected face region of a person included in an image of the second subsequent frame of the video data file does not conform to the registered face characteristic of a target in the region not to be masked,

excludes, the detected face region of a person included in an image of the second subsequent frame of the video data file, from targets to be masked, when the detected face region of a person included in an image of the second subsequent frame of the video data file conforms to the registered face characteristic of a target in the region not to be masked,

inputs a user's instruction which selects for masking a face region included in an image of the second subsequent frame of the video data file,

registers the face region selected by the user's instruction as an additional region to be masked, and

performs a masking process on regions to be masked which include the additional region.

2. The case video processing apparatus of claim 1 ,

wherein, in cooperation with the memory, the processor,

displays an image of the video data file to be processed on a display, and

displays a to be masked frame of the video data file which indicates the region to be masked in the image.

3. The case video processing apparatus of claim 1 ,

wherein, in detecting the face region of a person included in an image of the first frame of the video data file, the processor in cooperation with the memory detects a person included in an image of the first frame of the video data file, detects a face region from the person, and sets the face region as a region to be masked.

4. A case video processing method in a case video processing apparatus that performs image processing of a video data file including a first frame and a second subsequent frame and being related to a case, the case video processing method comprising:

inputting the video data file to be processed;

detecting a face region of a person included in an image of the first frame of the video data file;

registering the face region as a region to be masked;

inputting a user's instruction regarding the face region;

excluding a region designated by the user's instruction from targets to be masked and registering the region designated by the user's instructions as a region not to be masked;

registering a face characteristic of a target in a region not to be masked;

inputting a user's instruction which selects for masking an undetected face region of a person in the first frame of the video data file,

registering the undetected face region selected by the user's instruction as an additional target to be masked,

outputting video data having been subjected to image processing including excluding a region designated by the user's instruction from targets to be masked and masking the additional target;

detecting a face region of a person included in an image of the second subsequent frame of the video data file;

identifying the region to be masked which is registered for the first frame of the video data file;

determining whether the detected face region of a person included in an image of the second subsequent frame of the video data file conforms to the registered face characteristic of a target in the region not to be masked;

including, the detected face region of a person included in an image of the second subsequent frame of the video data file, in the targets to be masked, when the detected face region of a person included in an image of the second subsequent frame of the video data file does not conform to the registered face characteristic of a target in the region not to be masked;

excluding, the detected face region of a person included in an image of the second subsequent frame of the video data file, from targets to be masked, when the detected face region of a person included in an image of the second subsequent frame of the video data file conforms to the registered face characteristic of a target in the region not to be masked;

inputting a user's instruction which selects for masking a face region included in an image of the second subsequent frame of the video data file;

registering the face region selected by the user's instruction as an additional region to be masked, and

performing a masking process on regions to be masked which include the additional region.

5. The case video processing method of claim 4 , further comprising:

displaying an image of the video data file to be processed on a display, and

displaying a to be masked frame of the video data file which indicates the region to be masked in the image.
