Imaging apparatus and its control method and program

摘要

The imaging apparatus has: a first exposure mode in which an exposure condition is determined based on pixel data generated by photoelectrically converting, by a plurality of pixels, light rays entering through a pupil division unit, a state of vignetting of the photographing optical system is determined based on information about a construction of a photographing optical system, and an exposure condition is determined based on the pixel data selected from the pixel data generated in accordance with the vignetting state; and a second exposure mode in which an exposure condition is determined based on data obtained by adding the generated pixel data with respect to the exit pupil area of the photographing lens.

主权项

1. An imaging apparatus having an imaging element which has a plurality of pixels, each of which receives one of rays of light from one of a plurality of different exit pupil areas of a photographing optical system, comprising at least one processor that functions as:
an exposure condition determination unit configured to determine an exposure condition of the imaging element on the basis of pixel data which is generated by photoelectrically converting the rays of light by the plurality of pixels; and a vignetting determination unit configured to determine a state of vignetting of the photographing optical system on the basis of information about a construction of the photographing optical system, wherein the exposure condition determination unit has a first exposure mode for determining the exposure condition on the basis of the pixel data selected, in accordance with the state of vignetting, from the pixel data which is generated by photoelectrically converting the rays of light by the plurality of pixels, and a second exposure mode for deciding the exposure condition on the basis of data obtained by adding, with respect to the exit pupil areas, the pixel data which is generated by photoelectrically converting the rays of light by the plurality of pixels.
