Abstract

The embodiment of the invention relates to an image sensor and electronic equipment. The image sensor includes: a plurality of pixel unit groups, at least one pixel unit group comprises a color filterarray, wherein the color filter array comprises M first type filters, N second type filters and a light blocking area, the light blocking area comprises N light blocking sub-areas, and each light blocking sub-area is adjacent to the N second type filters; a pixel unit array positioned below the color filter array; wherein the pixel unit array comprises M first pixels and N second pixels, whereinthe M first pixels are in one-to-one correspondence with the M first type filters respectively, the N second pixels are in one-to-one correspondence with the N second type filters and the N light blocking sub-areas respectively, the area of the second pixels is larger than that of the first pixels, and M and N are integers larger than 0. According to the image sensor and the electronic equipment,the dynamic range of the image sensor is enlarged.

Description

technical field [0001] The embodiments of the present application relate to the image field, and more specifically, relate to an image sensor and an electronic device. Background technique [0002] A solid-state image sensor is a solid-state integrated component that converts optical image signals into digital signals. The solid-state image sensor includes a charge-coupled device (Charge-coupled Device, CCD) and a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS). Two types are widely used in consumer electronics, security monitoring, automotive electronics, and industrial manufacturing. [0003] The imaging principle of solid-state image sensors is based on the photoelectric conversion effect of semiconductor materials. A pixel array composed of a plurality of pixels is arranged on a semiconductor substrate, and each pixel contains a photoelectric conversion element and a readout circuit. When light is projected onto the pixel array, ...
