Solid-state image sensing device and camera system with divided pixels

摘要

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.

1. A solid-state image sensing device comprising:
a pixel part in which plural pixels are arranged in a matrix; and a pixel signal readout part including an AD conversion part that analog-digital (AD)-converts pixel signals read out from the pixel part, wherein each of plural adjacent pixels or individual pixels of the pixel part are respectively constituted as plural divided pixels that are divided into regions with different photosensitivity or amounts of accumulated charge, plural photosensitivity or exposure time conditions are respectively set for the plural divided pixels, with the photosensitivity or exposure time conditions of the divided pixels that are opposed in diagonal directions being set to the same conditions, the pixel signal readout part reads out divided pixel signals respectively corresponding to the divided pixels, and the AD conversion part obtains a given pixel signal of a given pixel by AD-converting and adding respective ones of the divided pixel signals that correspond to the given pixel.
