Problems solved by technology

[0002] Generally, the pixels on the image sensor have the same size and are evenly distributed on the image surface of the image sensor. Then, because the light gathering ability of the central area of ​​the convex lens is much greater than that of the edge area, the amount of light in the central area of ​​the image sensor is more. However, the amount of light in the edge area is less, which will cause vignetting effect and affect the image quality

Abstract

The application discloses an image sensor, a camera module and a terminal. The image sensor includes a pixel layer, the pixel layer includes a plurality of pixel units, the pixel layer includes a central area located at the center of the pixel layer and at least one edge area located around the central area, and the area of ​​the pixel units in the edge area is larger than that of the pixel units in the central area area. In image sensors, camera modules, and terminals, the pixel units in the pixel area closer to the center of the pixel layer are smaller, so that the pixel units in the central area that receive more light are smaller, and more pixels can be distributed to reduce the center area. The amount of light received by each pixel unit in the area; while the pixels in the edge area receiving less light are larger, and fewer pixels can be distributed to increase the amount of light received by each pixel unit in the edge area, so that the entire pixel layer The amount of light obtained by each pixel unit is basically the same, thereby reducing the vignetting effect and improving the imaging quality.

Description

technical field [0001] The present application relates to the technical field of consumer electronics, in particular to an image sensor, a camera module and a terminal. Background technique [0002] Generally, the pixels on the image sensor have the same size and are evenly distributed on the image surface of the image sensor. Then, because the light gathering ability of the central area of ​​the convex lens is much greater than that of the edge area, the light amount in the central area of ​​the image sensor is more. The less light in the edge area will cause vignetting effect and affect the image quality. Contents of the invention [0003] Embodiments of the present application provide an image sensor, a camera module, and a terminal. [0004] The image sensor in the embodiment of the present application includes a pixel layer, the pixel layer includes a plurality of pixel units, the pixel layer includes a central area located at the center of the pixel layer and at lea...
