Abstract

The invention provides a method for improving image output performance of an image sensor. The size of the diagonal line of the photosensitive area of the pixel array of the image sensor is larger than the diameter of the imaging circle of the lens assembled on the image sensor, pixel units which cannot be reached by the lens light in the four corner areas of the pixel array are used as dark pixelunits, and the image performance is improved.

Description

technical field [0001] The invention relates to the technical field of image sensors, in particular to a method for improving the image output performance of an image sensor. Background technique [0002] An image sensor is an important part of a digital camera. It is a device that converts an optical image into an electrical signal. It is widely used in digital cameras, mobile terminals, portable electronic devices and other electro-optical devices. According to different components, image sensors can be divided into two categories: CCD (Charge Coupled Device, Charge Coupled Device) and CMOS (Complementary Metal Oxide Semiconductor, Complementary Metal Oxide Semiconductor Element) image sensors. In addition to large-scale application in digital cameras, CCD image sensors are also widely used in video cameras, scanners, and industrial fields. The CMOS image sensor can be applied to digital cameras, PC cameras, mobile communication products and other fields due to its advant...
