1. An image sensor comprising:
a plurality of light-receiving elements that receive light from a subject and are arranged in a 2-dimensional form;
a detection unit that detects a movement amount of a projected image of the subject projected to the plurality of light-receiving elements arranged in the 2-dimensional form; and
a light-receiving element control unit that adaptively controls a timing at which pixel data is read from the plurality of light-receiving elements arranged in the 2-dimensional form for each line according to the movement amount,
wherein the light-receiving element control unit calculates a coefficient proportional to a reciprocal of a ratio of an exposure time, in which the light-receiving elements are reset and the pixel data is then read, to a proper exposure time, and
wherein the image sensor further comprises:
a multiplication unit that adjusts a gain by multiplying pixel data generated when some of the plurality of light-receiving elements arranged in the 2-dimensional form receive light by the coefficient.
