Problems solved by technology

[0002] Flat-panel TVs generally have disadvantages such as low contrast and not bright colors, etc., which require image enhancement processing in the video processing chip
At present, the color enhancement control of flat-panel TVs is based on the overall color enhancement of the video signal, that is, after the color enhancement adjustment, all colors will be enhanced accordingly, and the user's choice is very small, and it is not possible to individually adjust a single color according to the user's preference. Selective enhancement adjustments for colors

Embodiment

[0035] In this embodiment, the user selects the green area of ​​the enhanced TV screen through the remote control. The implementation process is shown in Figure 3. First, the format of the input image signal is converted from RGB format to HSV format, and then the color selected by the user is detected. The area is a green area, and then the color saturation component with a color phase angle of [90°, 150°] is subjected to color saturation segmented linear enhancement processing. In order to better improve the color brightness of the image, the color saturation signal is extended to [0, 255], and [0, 63] is taken as the dark area of ​​the color saturation signal, and the corresponding color saturation interval is [0, 0.25], take [64, 127] as the middle area of ​​the color saturation signal, the corresponding color saturation range is [0.25, 0.5], take [128, 191] as the sub-brightness area of ​​the color saturation signal, and the corresponding color saturation The interval is ...

Abstract

The invention relates to an image processing technology, in particular to an independent color enhancement processing method to the image. The invention discloses an independent color enhancement method which conducts the single color enhancement according to the color chosen by the user. The single color enhancement of the invention includes the procedures that: a. the input image is conversed from a RGB format into a HSV format; b. a color region which the user chooses is detected; c. a color saturation piecewise linear enhancement processing is carried out to the color saturation of pixel points in the chosen color region; d. the signal processed by the pixel points is preserved, so as to judge whether all the pixel points in the presently chosen color region are processed. If so, the image from the HSV format is conversed into the RGB format; if not, the next pixel point is processed and the third procedure is returned. The invention has the beneficial effects that color enhancement is selectively conducted in accordance with the preference of the user, and the aesthetic concept of the users is better satisfied.

Description

technical field [0001] The invention relates to image processing technology, in particular to a method for independently enhancing the color of an image. Background technique [0002] Flat-panel TVs generally have disadvantages such as low contrast and not bright colors, etc., and image enhancement processing needs to be performed in the video processing chip. At present, the color enhancement control of flat-panel TVs is based on the overall color enhancement of the video signal, that is, after the color enhancement adjustment, all colors will be enhanced accordingly, and the user's choice is very small, and it is not possible to individually adjust a single color according to the user's preference. Colors are selectively enhanced. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a color independent enhancement processing method, which performs individual color enhancement according to the color selected by the ...
