Abstract

Embodiments of the present application provide an image restoration method and device. The method includes: obtaining the first pixel set of the image to be restored, the pixel value of each pixel in the first pixel set is obtained through the red light R channel, the green light G channel, the blue light B channel or the infrared light IR channel Pixel value; according to the pixel value of each IR channel and the preset first interpolation rule, respectively determine the IR component corresponding to the pixel value of each R channel, G channel, and B channel in the first pixel set; remove each R channel, The IR component corresponding to the pixel value of the G channel and the B channel, the first pixel set is updated to the second pixel set; the R component or the B component corresponding to the pixel value of each IR channel in the second pixel set is determined, and the The second set of pixels is updated to a third set of pixels; according to the third set of pixels, the image to be restored is restored. This embodiment can reduce hardware cost.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image restoration method and device. Background technique [0002] With the continuous development of science and technology, the application of digital image acquisition equipment is becoming more and more extensive. The camera is an essential device for image acquisition equipment, and the image sensor is the photosensitive element in the camera. [0003] In order to solve the problem of daytime imaging that requires filter coordination, etc., RGB-IR image sensors came into being. The difference between the RGB-IR image sensor and the traditional image sensor is that the IR (Infra Red, infrared light) channel replaces the R (Red, red light) channel or the B (Blue, blue light) channel. Figure 1a It is a schematic diagram of a pixel data array output by a traditional image sensor, Figure 1b It is a schematic diagram of the pixel data array output by the ...
