1. An image processing device comprising
a processor configured to:
acquire a video captured based on a first video capturing mode or a second video capturing mode with an imaging condition that is different from an imaging condition of the first video capturing mode;
determine a quantization parameter of image data of a frame constituting the video; and
compress the image data with the quantization parameter,
wherein the processor is further configured to
determine the quantization parameter within a first range in a case of the first video capturing mode and determine the quantization parameter within a second range in a case of the second video capturing mode,
a second lower limit value of the second range is larger than a first lower limit value of the first range,
the second range is narrower than the first range, wherein
the imaging condition includes at least one of a shutter speed, a speed of autofocus, a tracking speed of automatic exposure, and a tracking speed of white balance, and
the imaging condition of the second video capturing mode is set faster than that of the first video capturing mode.
