Abstract
A solid-state image sensing device includes: a pixel part in which pixels are arranged in a matrix; and a pixel signal readout part including an AD conversion part that analog-digital (AD)-converts a pixel signal read out from the pixel part. Each of the adjacent pixels or one of the pixels of the pixel part is formed as divided pixels divided into regions with different photosensitivity or amounts of accumulated charge, photosensitivity or exposure time conditions are set for the divided pixels and the photosensitivity or exposure time conditions of the divided pixels provided to be opposed in diagonal directions are set to the same conditions, the pixel signal readout part reads out divided pixel signals of the respective divided pixels of the pixel, and the AD conversion part obtains a pixel signal of one pixel by AD-converting the respective read out divided pixel signals and adding the signals.
