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.

Abstract: The present invention provides an electric apparatus including an image sensor that starts to accumulate electric charges at different timings in different regions, and an optical filter that can be changed between a first concentration and a second concentration higher than the first concentration. The apparatus includes a first mode of executing a global shutter function so as to start exposure for each pixel included in a predetermined region of the image sensor at substantially the same timing, and a second mode of starting exposure for the respective pixels of the image sensor at different timings. A change in a pixel count of image data read out from the image sensor in accordance with information concerning an exposure time set by a user is larger in the first mode than in the second mode.
