    Abstract: An imaging apparatus includes: an imaging sensor; and at least one processor. The processor is configured to execute: imaging processing of acquiring a plurality of first frames, which are imaged at a first frame rate in a first exposure mode, through the imaging sensor; correction processing of performing electronic shake correction on the plurality of first frames on the basis of an amount of shake delivered to the imaging apparatus; and generation processing of generating motion picture data, which has a second frame having a second frame rate lower than the first frame rate, by synthesizing the plurality of first frames. In the first exposure mode, the processor sets m as a positive integer, and makes an exposure time for an mth first frame constituting the second frame shorter than an exposure time for an (m+1)th first frame.

    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.

    Abstract: The imaging element has a first and a second phase difference pixel region each including the plurality of phase difference pixels, and an imaging pixel region between the first and the second phase difference pixel region in the first direction. The processor is configured to cause the imaging element to perform imaging at a frame cycle, execute first readout processing of reading out a signal from the first phase difference pixel region during a first frame period, and execute second readout processing of reading out a signal from the second phase difference pixel region during a second frame period subsequent to the first frame period. A first exposure time, during which the first phase difference pixel region is exposed, and a second exposure time, during which the second phase difference pixel region is exposed, are different from an exposure time of the imaging pixel region.
