2) and produce the color compensation data.Suppress unit 24 and couple compensating unit 22, in order to suppress the color compensation data, again according to the input of the color compensation compensation data pixel after suppressing data, to produce pixel data output.So, can avoid the color compensation data excessive and make the chromatic characteristic of the pixel input data after the compensation not meet user's object color component characteristic.Wherein, suppress unit 24 and can be considered distortion suppression, it determines that according to pixel input data one suppresses parameter (Gain), and suppresses the color compensation data according to suppressing parameter, namely shown in following equation:
Based on above-mentioned, compensating unit 22 can transmit the color compensation data to suppressing unit 24, and suppressing unit 22 can be multiplied by the color compensation data with the inhibition parameter, and the color compensation data after will suppressing again add pixel input data, with compensation pixel input data, and produce and output pixel output data.
See also shown in Figure 3, pixel input data comprise this a plurality of primary color data, suppressing unit 24 is to deduct minimum primary color data by the maximum primary color data in these a plurality of primary color data, and decision suppresses the size of parameter, for example deduct minimum value between d～e the time when the maximal value of these a plurality of primary color data, then suppressing parameter Gain is 1, namely do not need the color offset data is suppressed, when the maximal value of these a plurality of primary color data deducts minimum value between a～d or between e～g, then suppress parameter Gain and can correspond to 0.2～0.8, to avoid the color compensation data excessive.
In addition, although above-mentioned is that maximal value with these a plurality of primary color data deducts minimum value and decides the size that suppresses parameter, but the present invention is not limited to above-mentioned method and decides the size that suppresses parameter, also available this a plurality of primary color data intermediate value or mean value etc. the size that decides the inhibition parameter.Moreover, compensating unit 22 of the present invention also can be after compensation pixel be inputted data, pixel after compensation input data are sent to inhibition unit 24, pixel input data with after the inhibition compensation that is to say that the color compensation data that compensating unit 22 of the present invention can produce itself add pixel input data, with compensation pixel input data, and pixel is inputted data be sent to and suppress unit 24, suppressing unit 24 and suppress again pixel input data, it is shown in following equation:
Namely suppressing unit 24 can after compensating unit 22 is finished color compensation compensation data pixel input data, suppress pixel data output again.
Seeing also Fig. 4, is the calcspar of another preferred embodiment of color adjusting device of the present invention.As shown in the figure, different the locating of embodiment of the present embodiment and Fig. 1 is that the present embodiment compensating module 20 only comprises a compensating unit 26.Compensating unit 26 is adjusted parameter according to these a plurality of colors and is produced the color compensation data with these a plurality of color parameter, compensating unit 26 is according to color compensation compensation data pixel input data, to produce pixel data output, do not suppress the color compensation data and do not need to suppress unit 24 (as shown in Figure 1).
Please consult again Fig. 1, acquisition unit 10 except these a plurality of primary color data are compensated with proofread and correct, acquisition unit 10 more produces luminance parameter v according to pixel input data, compensating module 20 receives luminance parameter v again, and (is μ according to a plurality of brightness adjustment parameters
