Embodiment Construction

[0024] The present invention proposes a color adjustment device and a color adjustment method in view of the problems in the prior art, which can properly adjust the color image without judging or detecting pixel input data belonging to skin tone in a color image by means of table lookup. The color characteristics of some pixel input data can improve the shortcomings of the existing color adjustment methods, and can reduce costs and save system resources, so as to solve the above problems.

[0025] Please refer to figure 1 , figure 1 It is a functional block diagram of a color adjustment device 1 according to an embodiment of the present invention. The color adjustment device 1 of the present invention expresses a pixel input data in multiple formats, and judges whether the pixel input data expressed in different formats belong to a specified color tone (ie, skin tone). Accordingly, the color adjustment device 1 can detect pixel input data belonging to skin tone, and perform...

Abstract

The invention discloses a color adjusting apparatus and a color adjusting method. The color adjusting apparatus includes a capturing module for receiving pixel input data; a detecting unit for detecting whether the pixel input data belongs to specified hue so that a hue determination result is produced; a capturing unit for producing multiple hue parameters on the basis of the pixel input data; a first compensation module coupled to the capturing module and used for compensating the pixel input data according to the multiple hue parameters so that first pixel compensation data is produced; and a mixing unit, which is coupled to the capturing module and the first compensation module, and is used for producing pixel output data on the basis of the pixel input data, the first pixel compensation data and the hue determination result.

Description

technical field [0001] The invention relates to a color adjustment device and a color adjustment method, in particular to a color adjustment device and a color adjustment method capable of detecting a specified hue. Background technique [0002] A display device is a must-have for many electronic products today, such as various types of computer systems, smart mobile phones, or various touch-sensitive electronic devices. In addition to displaying text, the display device can also play still images or dynamic images. Most of the images displayed by the existing display devices are color images, which can achieve a more vivid and realistic effect, so as to provide users with better visual experience. [0003] Nowadays, in order to improve the display quality of display devices, various manufacturers are all committed to improving the ability of display devices to display color images, so that the color images are closer to real scenes. Therefore, most of the display devices ...
