Problems solved by technology

Therefore, if we do not consider the individual visual preferences of human beings, and do not judge the color attributes displayed by the pixels themselves at that time, but only increase or decrease the saturation or brightness together, the user cannot obtain the best visual effect.

Embodiment Construction

[0029] Since human vision does not have a consistent preference for saturation or brightness of all colors, the traditional method of adjusting the saturation or brightness of all colors at the same time cannot satisfy the user's human vision and personal preference.

[0030] The present invention first converts the color attributes of each pixel data into HSV color coordinates, and then adjusts the converted color attributes respectively, so that each pixel data conforms to human vision and personal preferences of users. Any color attribute (such as hue, saturation, or brightness) of each pixel data will be adjusted by considering the hue (H), saturation (S) and brightness (V) at the same time. The adjustment relationship of these three color attributes can be expressed as follows:

[0031] H'=f(H,S,V), S'=f(H,S,V); and V'=f(H,S,V).

[0032] In other words, the adjustment of hue is related to the hue, saturation and brightness of the pixel data; the adjustment of saturation ...

Abstract

The invention provides a color image enhancement device and method. The color image enhancement device includes a color attribute judger and a color attribute adjuster. The color attribute judger generates an adjustment signal according to the hue, saturation and brightness of a pixel data, wherein the adjustment signal adjusts the hue, saturation and brightness separately by the hue, saturation and brightness of the pixel data. Decide. The color attribute adjuster is connected to the color attribute judger. The color attribute adjuster is used for receiving an adjustment signal, and adjusts the pixel data according to the adjustment signal. The color image enhancement device and method of the present invention can adjust pixel data according to different hue, saturation or brightness, enhance its color performance, and allow users to have a better viewing effect visually.

Description

technical field [0001] The invention relates to an image device, and in particular to a color image enhancement device and method. Background technique [0002] From the earliest cathode ray tube monitors to the more recent liquid crystal monitors that have gradually become mainstream, monitors have always been an indispensable tool for modern people to exchange information. The cathode ray tube display has been very mature in various application fields, especially in the application of television and computer display, the cathode ray tube display provides rich color performance. CRT displays are less suitable for notebook computers and personal digital assistants (PDAs) due to size and weight considerations. Liquid crystal displays have gradually replaced traditional cathode ray tube displays in various application fields because of their small size and light weight. [0003] The traditional method of recording the color attributes of digital images, such as expressing th...
