Image sensor and electronic device

Abstract

The present application belongs to the technical field of sensors. Disclosed are an image sensor and an electronic device. The image sensor comprises: a pixel array and a color filter array, wherein the pixel array comprises at least one multispectral unit, each multispectral unit comprises at least two first-type pixels for image imaging and at least two second-type pixels for multispectral imaging, and each multispectral unit is composed of at least one multispectral element, each multispectral element corresponding to four basic color channels, each basic color channel corresponding to 16 pixels distributed in a 4×4 array in the pixel array, and each filter element in a filter unit corresponding to one pixel of the pixel array; and the color filter array comprises at least one filter unit arranged opposite the at least one multispectral unit, and each filter unit comprises at least two first-type filter elements and at least two second-type filter elements, the first-type filter elements being arranged opposite the first-type pixels, and the second-type filter elements being arranged opposite the second-type pixels.
