Abstract

The embodiment of the application provides an image restoration method and device. The method comprises the following steps: acquiring a first pixel set of an image to be restored, wherein the pixel values of pixels in the first pixel set are pixel values obtained through red light R channels, green light G channels, blue light B channels or infrared light IR channels; determining IR components corresponding to the pixel values of the R channels, the G channels and the B channels in the first pixel set according to the pixel values of the IR channels and a preset first interpolation rule; removing the IR components corresponding to the pixel values of the R channels, the G channels and the B channels, and updating the first pixel set into a second pixel set; determining R components or B components corresponding to the pixel values of the IR channels in the second pixel set, and updating the second pixel set into a third pixel set; and restoring the image to be restored according to the third pixel set. Through adoption of the image restoration method and device in the embodiment, the hardware cost can be lowered.

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 ...
