Image pickup apparatus having same exposure time among pixel groups and associated method and computer-readable medium

摘要

An image pickup apparatus includes an image pickup element to obtain an image of a subject using a plurality of pixels which are classified into a plurality of pixel groups and are arranged in a matrix pattern, a controller to apply a reset signal to start exposure of a pixel on a pixel group basis in sequence, to read out pixel values of the plurality of pixel groups on the pixel group basis in sequence according to the reset signal applying order, and to control the image pickup element such that each of the pixel groups has a same exposure time, and a storage unit to store the pixel values read out on the pixel group basis in sequence.

1. An image pickup apparatus, comprising:
an image pickup element to obtain an image of a subject using a plurality of pixels which are classified into a plurality of pixel groups and are arranged in a matrix pattern; a controller to apply a reset signal to start exposure of a pixel on a pixel group basis in sequence, to read out pixel values of the plurality of pixel groups on the pixel group basis in sequence according to the reset signal applying order, and to control the image pickup element such that each of the pixel groups has a same exposure time; a storage unit to store the pixel values read out on the pixel group basis in sequence; and an image processing unit to perform exposure compensation to correct an amount of light for each of the plurality of pixel values in a pixel group of the plurality of pixel groups in a situation in which an exposure time for a first pixel of the pixel group is shorter than the exposure time for a second pixel of the pixel group.
