Correcting method for pseudo color pixel in digital image

Abstract

The present invention discloses a method for correcting pseudo color pixel in digital image. The method is used for correcting the pseudo color pixel which is generated after a color correction array processing. The method comprises the following steps: obtaining an original image, generating processed image after the color correction array processing; comparing the pixel of original image and the pixel of processed image according to color diversity factor for finding out the pseudo color pixel in the processed image; executing color correction processing to the original image and the pseudocolor pixel at the corresponding position of processed image, and correcting the pseudo color pixel according to the pixel color at the corresponding position of original image.

Description

technical field [0001] The invention discloses a digital image processing method, in particular to a color correction method for false color pixels in the digital image. Background technique [0002] The human eye's recognition of color is based on the principle that the human eye has three different sensing units for light, and different sensing units have different response curves to different bands of light. The perception of color is obtained through the synthesis of the brain. Generally speaking, we can use the concept of the three primary colors of red, green and blue to understand the decomposition and synthesis of colors. [0003] The photosensitive components of digital cameras are not exactly the same as the human eye's response to red, green and blue light. Since the response of the photosensitive component to the spectrum is usually different from the response of the human eye to the spectrum in terms of the components of red, green and blue light, of course it ...
