Electronic device, imaging device, and imaging element
An electronic device includes: an imaging unit including a region having a pixel group that has a plurality of first pixels, and second pixels that are fewer than the first pixels in the pixel group; and a control unit that reads out the signals based upon exposure of the second pixels during exposure of the plurality of first pixels.
1. An electronic device comprising:
an imaging element that includes a first image capture region that captures an image of a subject, and a second image capture region that is arranged separately along a first direction and along a second direction that intersects the first direction, the second image capture region being smaller that the first image capture region;
a control unit that makes timing at which charges accumulated in the first image capture region are read out and timing at which charges accumulated in the second image capture region are read out be different from each other;
a display device that is capable of displaying a first image that is generated by image capturing in the first image capture region and a second image that is generated by image capturing in the second image capture region; and
a display control unit that displays the second image that is generated by image capturing in the second image capture region, while the electronic device is performing photography longer than a predetermined time period.
2. An electronic device comprising:
an imaging element that includes a first image capture region that captures an image of a subject, and a second image capture region that is arranged separately along a first direction and along a second direction that intersects the first direction, the second image capture region being smaller that the first image capture region;
