The invention relates to an image processing method, which belongs to the field of digital image processing. The image processing method comprises the following steps that S1 a red component, a green component and a blue component of each pixel of an image are obtained; S2 in the process that an image frame is invalid, a color correction matrix, a color gamut space transformation matrix or a combined matrix for calculating the product of the color correction coefficient calculation matrix and the color gamut space transformation matrix is set; and S3 in the process that an image line is valid, the color correction matrix, the color gamut space transformation matrix or the combined matrix is utilized to correct the red component, the green component and the blue component of each pixel of the image. According to the image processing method, image processing can be selected as required; if color correction and space transformation are performed simultaneously, the combination of the color correction coefficient matrix and the color gamut space transformation matrix and image correction are at different time; a multiplier can be recycled; and the use of the multiplier is reduced, thereby achieving the effect of reducing a circuit area.
Description
technical field [0001] The invention belongs to the field of digital image processing, in particular to an image processing method. Background technique [0002] In the prior art, due to the influence of the characteristics of the color filter (colorfilter), the color of the image taken by the CMOS image sensing device is often not correct, that is, the color of the image coming out of the CMOS sensor has a color shift, which requires a certain method to correct it. A known correction method is: [0003] Take a picture of a color checker (colorchecker)—a standard color palette, calculate the average value of each color block in the captured image, compare it with the standard value of the corresponding color block in the standard color palette, and estimate the color correction matrix ( The direction and range of each correction coefficient (colorcoefficient) in the colormatrix should be adjusted until the purpose of color correction is achieved. The color correction formu...
