Embodiment Construction

[0038] figure 1 It is a flow chart illustrating a method for processing image color according to an embodiment of the present invention.

[0039] Such as figure 1 As shown, in step 102, the number of pixels of each color in the image is counted and saved.

[0040] In step 104, the merging coefficient between each two colors is calculated according to the value of the color in the color space and the number of pixels of the color, that is, the similarity between each two colors. There are many methods that can be used to measure the similarity of two colors in the color space, and the preferred embodiment of calculating the merge coefficient of the present invention will be described in detail later.

[0041]In step 106, the two colors with the smallest merging coefficients are merged into a new color, and the value of the new color in the color space is calculated according to the values ​​of the two colors in the color space and the corresponding number of pixels. In one e...

Abstract

The invention provides a method for image color processing and an image processing device. the method for image color processing comprises the following steps: calculate pixel number of color of image; calculate merging coefficient between any two colors according to the value of color in the color space and the pixel number of color; the two colors with smallest merging coefficient are combined into a new color, and the value of the new color replaces the value of the two merged colors in image. The method and the image processing device have the advantages of simple calculation, fast speed,and flexible realization, etc.

Description

technical field [0001] The present invention relates to image processing technology, in particular to a method for processing image color and image processing equipment. Background technique [0002] In some devices such as embedded devices, due to the limitation of display performance, only OSD (On Screen Display, screen menu adjustment method) with 256 colors or less can be supported. When the number of colors of an image exceeds the number of supported colors, the image cannot be displayed directly. In this case, the number of colors of the image needs to be adjusted to the number of colors supported by the device in order to display the image. Adjusting the number of colors of an image can be done with the help of some general image processing software. However, general-purpose image processing software lacks flexibility, and cannot well solve problems such as special settings such as transparent colors and joint display of images and text. If manual methods are used ...
