Image sensor and image sensor system

摘要

A MOS image sensor and an imaging apparatus using this image sensor enable controlling sensor driving with a high degree of freedom using a simple control circuit design and minimal wiring lines. The light reception unit of the image sensor in this imaging apparatus is segmented into a plurality of areas and conventional shift registers are constructed in multiple layers, thus enabling controlling the multiple sensor areas by means of a relatively simple circuit design. The imaging apparatus can thus locally change exposure and imaging conditions in parts of a single frame. Problems due to underexposure and overexposure are thus suppressed, and images with a wide dynamic range can be captured.
