2) and produce color compensation data.Unit 24 is suppressed to couple compensating unit 22, in order to suppress color compensation data, then according to the color compensation compensation data pixel input data after suppressing, to produce pixel data output.So, color compensation data can be avoided excessive and the chromatic characteristic of pixel input data after making compensation does not meet the object color component characteristic of user.Wherein, suppress unit 24 to can be considered distortion suppression, it determines a suppression parameter (Gain) according to pixel input data, and according to suppressing parameter to suppress color compensation data, namely as shown in following equation:
Based on above-mentioned, compensating unit 22 can transmit color compensation data to suppressing unit 24, suppresses unit 22 suppression parameter can be multiplied by color compensation data, then the color compensation data after suppressing are added pixel input data, with compensation pixel input data, and produce and output pixel output data.
See also shown in Fig. 3, pixel input packet is containing the plurality of primary color data, unit 24 is suppressed to be deduct minimum primary color data by the maximum primary color data in the plurality of primary color data, and determine the size suppressing parameter, such as when the maximal value of the plurality of primary color data deduct minimum value between d ~ e time, then parameter Gain is suppressed to be 1, namely do not need to suppress color offset data, when the maximal value of the plurality of primary color data deduct minimum value between a ~ d or between e ~ g time, parameter Gain is then suppressed to correspond to 0.2 ~ 0.8, to avoid color compensation data excessive.
In addition, deduct with the maximal value of the plurality of primary color data the size that minimum value decides to suppress parameter although above-mentioned, but the present invention is not limited to the size that above-mentioned method decides to suppress parameter, also can decide by the intermediate value or mean value etc. of the plurality of primary color data the size suppressing parameter.Moreover, compensating unit 22 of the present invention also can after compensation pixel inputs data, pixel input data after compensating are sent to suppression unit 24, to suppress the pixel input data after compensating, that is, the color compensation data that itself produces can be added pixel input data by compensating unit 22 of the present invention, with compensation pixel input data, and pixel is inputted data be sent to suppress unit 24, suppress unit 24 suppress again pixel input data, it is as shown in following equation:
Namely unit 24 is suppressed at compensating unit 22 after completing color compensation compensation data pixel input data, then can to suppress pixel data output.
Referring to Fig. 4, is the calcspar of another preferred embodiment of color adjusting device of the present invention.As shown in the figure, the place that the present embodiment is different from the embodiment of Fig. 1, is that the present embodiment compensating module 20 only comprises a compensating unit 26.Compensating unit 26 produces color compensation data according to the plurality of color adjustment parameter and the plurality of color parameter, compensating unit 26 is according to color compensation compensation data pixel input data, to produce pixel data output, and do not need to suppress unit 24 (as shown in Figure 1) to suppress color compensation data.
Please consult Fig. 1 again, acquisition unit 10 except the plurality of primary color data is compensated with correct except, acquisition unit 10 more produces luminance parameter v according to pixel input data, and compensating module 20 receives luminance parameter v again, and according to multiple brightness adjustment parameter (i.e. μ
rμ
gμ
b) produce luminance compensation data with luminance parameter v, so, compensating module 20 more can produce pixel data output according to the brightness of luminance compensation compensation data pixel input data.In addition, luminance parameter v can be one of them of pixel input data (i.e. the plurality of primary color data), and the present invention is that minimum primary color data in the plurality of primary color data is as luminance parameter v, be the first above-mentioned master data, above are only an embodiment, the present invention does not limit to can only using minimum primary color data as luminance parameter v, also can using the maximal value in the plurality of primary color data or intermediate value as luminance parameter.
In sum, the present invention is a kind of color adjusting device for display device and color adjustment method, and it is available for users to the chromatic characteristic being easy to adjust pixel input data, and the color of the image shown to allow display device more meets the vision perception of user.Color adjusting device of the present invention comprises acquisition unit and compensating module, acquisition unit produces multiple fictitious primary color data and multiple complementary color data according to pixel input data, and produce multiple color parameter according to the plurality of fictitious primary color data and the plurality of complementary color data, and compensating module is according to the plurality of color parameter compensation pixel input data, to produce pixel data output.Color adjusting device of the present invention and color adjustment method do not need to convert the form that pixel inputs data, data can be inputted by compensation pixel, and adjust the chromatic characteristic of pixel input data, so be easy to the chromatic characteristic of the image adjusting display device display, to meet the vision perception of user.
