Image processing device, image capturing device, image processing method, and image processing program

An image processing device comprising:

• a processor configured to
• acquire a video with a variable image capturing frame rate, as a video acquisition section;
• select first compression processing or second compression processing, as a compression processing selection section;
• compress the video acquired by the video acquisition section and perform the first compression processing or second compression processing, selected by the compression processing selection section, as a compression processing section;
• and
• generate a video file of the video compressed by the compression processing section, as a video file generation section,
• wherein in the second compression processing, a change in a capacity of the compressed video per one frame with respect to the change in the image capturing frame rate is set to be small, as compared with in the first compression processing,
• the compression processing selection section selects the first compression processing or the second compression processing, according to an environment of a device connected to the video file generation section, and
• the environment is any one of a transfer speed of a recording medium or a communication interface, which is connected to the video file generation section, or a remaining capacity of the recording medium.

An image processing method comprising:

• acquiring a video with a variable image capturing frame rate;
• selecting first compression processing or second compression processing;
• compressing the acquired video and performing the selected first compression processing or second compression processing;
• and
• selecting a first video capturing mode or a second video capturing mode in which an exposure time per frame is set to be shorter than that in the first video capturing mode,
• wherein in the second compression processing, a change in a capacity of the compressed video per one frame with respect to the change in the image capturing frame rate is set to be small, as compared with in the first compression processing, and
• in selecting the first compression processing or the second compression processing, the first compression processing is selected in a case where the first video capturing mode is selected and the second compression processing is selected in a case where the second video capturing mode is selected.
