    Abstract: Provided are an image processing device capable of performing compression processing on a video captured in each video capturing mode according to a first video capturing mode and a second video capturing mode with different capturing conditions. A possible range of a quantization parameter applied in a case where the video is compressed is made different in the first video capturing mode and the second video capturing mode with different capturing conditions. The quantization parameter is determined within a first range in a case of the first video capturing mode, and the quantization parameter is determined within a second range narrower than the first range in a case of the second video capturing mode. In particular, a second upper limit value of the second range is smaller than a first upper limit value of the first range, and a second lower limit value of the second range is larger than a first lower limit value of the first range.

    Abstract: Provided is an imaging apparatus that obtains a video with a resolution of satisfactory quality and a small angle of view from a video with a large angle of view through real-time image processing. An imaging apparatus has an imaging element that captures an optical image of a standard video with a first angle of view, and a control unit that includes a first mode and a second mode as a video imaging mode and records video data of a video based on the optical image. The control unit executes first recording processing of recording video data of the standard video using the imaging element in the first mode. The control unit executes setting processing of setting a recording region with a second angle of view smaller than the first angle of view in the standard video and second recording processing of recording a video data of a recorded video of the recording region in the second mode. In the first recording processing and the second recording processing, thinning-out drive to thin out a part of readout of a plurality of pixels in the optical image is executed. A second thinning-out rate of the thinning-out drive of the second recording processing is set to be lower than a first thinning-out rate of the thinning-out drive of the first recording processing.
