Abstract

The invention discloses a method and device for acquiring RGB data, including acquiring a first horizontal interpolation result and a first vertical interpolation result of a pixel corresponding to the R channel / B channel in an image; acquiring the horizontal gradient and the vertical gradient of the pixel corresponding to the R channel / B channel in the image; determining that the absolute value of the difference of the horizontal gradient and the vertical gradient is greater than 0 and less than a first preset threshold, and reconstructing the pixel value of the G channel of the pixel corresponding to the R channel / B channel in the image based on the weight average of the first horizontal interpolation result and the first vertical interpolation result; reconstructing the pixel values of the R channel and the B channel of the pixel corresponding to the G channel in the image; and reconstructing the pixel value of the B channel of the pixel corresponding to the R channel in the image and the pixel value of the R channel of the pixel corresponding to the B channel in the image based on the reconstructed pixel value of the G channel of the pixel corresponding to the R channel and the B channel in the image. The method and device for acquiring RGB data reduce pseudo colour and moire and improve the visual quality of images.

Description

technical field [0001] The invention relates to image processing technology, in particular to a method and device for acquiring red, green and blue (RGB, RedGreenBlue) data. Background technique [0002] Most existing image sensors such as Complementary Metal Oxide Semiconductor (CMOS, Complementary Metal Oxide Semiconductor), in the process of acquiring images, each pixel has only one of the three channels of RGB data, therefore, it is necessary to demosaic the image, that is, use interpolation The method to get the missing data, so as to get the complete RGB data. [0003] Existing methods for obtaining RGB data roughly include: [0004] First, the pixel value of the G channel of the pixel corresponding to the R channel and the B channel in the reconstructed image; specifically, the pixel value of the G channel of the pixel corresponding to the R channel in the reconstructed image is used for illustration, and the pixel value of the pixel corresponding to the B channel in...
