Patent ID: 11716552

Abstract:
An imaging element of an imaging unit 24 divides the exit pupil of an imaging optical system 21 into a plurality of regions and generates a pixel signal for each region. An optical axis position adjustment unit 23 adjusts the optical axis position of the imaging optical system with respect to the imaging element. A control unit 26 calculates a parallax on the basis of the pixel signal for each region after the pupil division and performs focus control of the imaging optical system 21. The control unit 26 also moves the optical axis position using the optical axis position adjustment unit 23, and generates, using the imaging element, pixel signals indicating the same subject region in the plurality of regions after the pupil division. An image processing unit 25 performs binning of a plurality of pixel signals indicating the same subject region generated by moving the optical axis position to generate a high-resolution captured image. Calculation of the parallax and acquisition of a high-resolution captured image can be performed.
