Abstract
An image capturing apparatus comprises a plurality of pixels and a correction unit. Each pixel includes: a photoelectric converter; first and second charge holding sections to hold charges obtained with first and second charge accumulation periods in a first frame; third and fourth charge holding sections to hold charges obtained with the first and second charge accumulation periods in a second frame; a first floating diffusion portion for reading out charges held in the first and second charge holding sections in the second frame; and a second floating diffusion portion for reading out charges held in the third and fourth charge holding sections in the first frame. The correction unit corrects a difference between signal levels of signals read out via the first and second floating diffusion portions based on a difference between capacitances of the first and second floating diffusion portions.
