Fake color inhibition method for digital image

A digital image and false color technology, applied in color signal processing circuits, picture signal generators, etc., can solve the problems of inability to balance the complexity of image processing and visual effects, and the inability to achieve a balance between the complexity of image processing and the sacrifice of chroma. Achieve the effect of suppressing false color, low chroma sacrifice, and low computational complexity

Problems solved by technology

In other words, the current false color suppression technology is still unable to achieve a balance between the complexity of image processing and the sacrifice of chroma
[0004] Therefore, there is a problem that the image processing complexity and visual effect of suppressing false colors in the prior art cannot be balanced

Embodiment Construction

[0030] The purpose of the present invention and the proposal are described in detail in the following preferred embodiments. However, the concept of the invention can also be used in other areas. The following examples are only used to illustrate the purpose and implementation method of the present invention, and are not intended to limit the scope thereof.

[0031] figure 1 It is a flow chart of the false color suppression method for digital images. Please refer to figure 1 , in this embodiment, the false color suppression method of digital image is carried out by digital camera, to suppress the false color in the digital image that digital camera shoots, and it comprises the following steps:

[0032] Firstly, decompose the luminance part and the chroma part of the digital image (step S110). Next, take out the chroma part, and calculate the first color gamut component and the second color gamut component in the chroma part (step S120). Afterwards, a threshold value is se...

Abstract

This invention discloses a false color inhibiting method for digital image. This method is carried out by digital camera to inhibit false color of digital image shot by digital camera, comprising: decomposing brightness part and color part of digital image; extracting color part, and calculating a first color range component and a second color range component in color part; setting threshold value according to photosensibility during shooting of digital camera; according to relations between differences of pixel and adjacent pixel and the threshold value, carrying out corresponding pixel homogenization on the pixel respectively relating to the first color range component and the second color range component; then converging homogenized color part and brightness part of digital image into inhibited image.

Description

technical field [0001] The invention relates to a digital image processing method, and in particular to a digital image false color suppression method. Background technique [0002] The so-called color of the human eye is actually the visible light reflected by the object after absorbing most of the light spectrum in the light. For example, after the green leaves absorb most of the spectrum of light, the human eyes receive the reflected green visible light, which becomes the green leaves that people see. In nature, if red light, green light and blue light are mixed according to a certain ratio, a variety of different colors can be obtained. In computer-related fields, the three primary colors of red, green, and blue are also used as the color mixing benchmark of colors. For example, RGB is a method of encoding colors, which uses several bytes to represent the intensity of the three primary colors of red, green, and blue, so as to represent a variety of different colors. C...
