Corresponding to the initial state, the color lean R1G1B1 input to the digital color adjustment device will be rotated directly without any color adjustment. In this embodiment, the digital color adjustment of the display can be divided into three types: (1) performing color gamut matching adjustment of the display; (2) performing independent color adjustment of the display, and (3) simultaneously performing color gamut of the display; Match and independent color adjustment. The manner in which they are used is described below. (1) Performing color gamut matching adjustment of the display A basic test pattern for performing gamut matching adjustment of the display is shown in Fig. 4, and the test pattern is displayed on the display 14'. In Figure 4, the squares R/G/B/C/M/Y are red, green, blue, cyan, magenta, and yellow color patches, respectively, for the observer to evaluate immediately or adjust the color with the instrument. result. The software interface of the gamut matching adjustment of the display is shown in Figure 5. Use • After selecting the color axis to be adjusted, drag the hue difference reel to change the output hue value of the color axis, or drag the saturation gain reel to change the output saturation of the color car. After the user inputs the hue difference adjustment value and the saturation matching adjustment value, the embodiment establishes a continuity adjustment curve by a numerical method. For example, if the user increases the red hue by 10 and the green hue by 1〇, and the yellow saturation by 1.2 times and the blue-green saturation by 〇·8 times, the established hue difference correspondence table and saturation matching correspondence table are as shown in FIG. 6. Show. 12 doc/g I2955^Uwf, Next, how the gamut matching adjustment is performed in this embodiment will be described. Please refer to Fig. 7, which shows a flow chart of how the gamut matching adjustment is performed in this embodiment. First, the user selects the color axis to be adjusted, as shown in steps 7-8. Then drag the hue reel to change the hue difference value of the color axis, or drag the saturation reel to change the output saturation of the color axis, as shown in step 71. The so-called multi-axis refers to at least three color adjustment axes and up to 12 color adjustment axes. The input mode of the user can be as shown in FIG. 5, and details are not described herein again. Then, the human-machine interface establishes the continuity adjustment curve of the hue difference correspondence table and the saturation matching correspondence table by the numerical method according to the multi-axis hue difference value and the saturation matching value, as shown in step 712. The saturation matching adjustment value can be achieved in a linear manner and in a non-linear manner. Thereafter, the human machine interface 160 transmits the established hue difference correspondence table and the saturation matching correspondence table (for example, as shown in FIG. 6) to the digital color adjusting device 120 to update the hue difference correspondence table 245 in the digital color adjusting device 120. The saturation match corresponds to table 235, as shown in step 714. As described above, when the hue difference correspondence table 245 and the saturation matching correspondence table 235 are updated, the Η 4 and C 4 signals are affected, so that the signal R6G6B6 output by the digital color adjusting device 丨 2 产生 changes, that is, The test pattern on display 140 changes. Next, the adjusted test pattern displayed on display 14A is evaluated by an observer or instrumented to evaluate the results to confirm compliance with the test pattern as adjusted, as shown in steps 716 and 718. If the requirements are met, then the gamut matching adjustment has been achieved. If the requirements are not met, the user selects the color axis again and enters the multi-axis hue difference value of the other group with the saturation 13 12955Alotwf.doc/g match value 'until to match The effect of color adjustment. The adjustment of the saturation matching value can be constructed in a linear manner and in a non-linear manner. (2) Performing independent color adjustment of the display The software interface of the display independent color output adjustment is shown in Fig. 8 as an example. As for the independent hue process, it is shown in Figure 1. First, the user records and selects the independent color (such as skin color, sky color, etc.) to be adjusted, as shown in step 1〇〇1. Next, the user inputs/changes the hue difference value and the saturation match value of the independent color as shown in step 1003. The detailed implementation of step 1〇〇3 is, for example, the user dragging the hue reel to change the hue difference value of the color, and dragging the saturation reel to change the output saturation of the color. Next, the human-machine interface 160 calculates the hue difference correspondence table and the saturation matching correspondence table of the continuity curve by a numerical method, as shown in step 1〇〇5. For example, if the user increases the hue of the skin color by 5 and the saturation by 1.4 times, and the hue of the sky is reduced by 5 and the saturation is increased by 1.2 times, the established hue difference correspondence table and the saturation matching correspondence table are as shown in FIG. . Next, the established hue difference correspondence table and the saturation matching correspondence table are downloaded to the color adjustment device via the human interface, as shown in step 1007. The adjusted test pattern displayed on display Η0 is then evaluated by an observer or instrumented to evaluate the results to confirm compliance with the test pattern as shown in steps 1009 and 1011. If the requirements are met, the independent hue is achieved. If the requirements are not met, the user performs steps 1001 to 1007 again until the desired adjustment effect of the independent color is met. 12955^Utwf.d〇c/g The above independent color adjustment represents color adjustment for a certain range, and the adjustment result only affects the color gamut near the selected color, dryness and degree 0 (3) while displaying ϋ The process of matching the color gamut matching and the independent color gradation of the display simultaneously with the independent color adjustment is not shown first. The user selects the color axis and the independent color to be adjusted, as shown in step 1201. Here, the user can select the color axis and the independent color through the soft body of FIG. 5 and FIG. Then, drag the hue reel to change the hue difference value of the "black axis" or drag the saturated reel to change the output saturation of the color axis, as shown in step 12〇3. The so-called multi-axis is at least three. Color adjustment axis, the most home 12 color adjustment axis. Or, the user inputs/changes the hue difference value and the saturation match value of the independent color, as shown in step 12〇5. Step 12〇5, ocean, and field methods are The user drags the hue reel to change the hue difference value of the color, and can also drag the saturated reel to change the output dryness of the color. %Note: The order of implementation of steps 1203 and 1205 is not fixed, and the order can be mutually Next, the human-machine interface 160 calculates the hue difference correspondence table and the saturation matching correspondence table of the continuity curve by a numerical method, as shown in step 1207. The established hue difference correspondence table and the saturation matching correspondence table are as shown in FIG. No. The established hue difference correspondence table and the saturation matching correspondence table are downloaded to the color adjustment device via the human machine interface, as shown in step 1209. Then 'is evaluated by the observer or measured by the instrument. The adjusted test pattern on the display 14〇 is used to evaluate the result to confirm whether the test pattern has been adjusted to meet the requirements, as shown in steps 1211 and 1213. If it meets the requirements of 12 9 5 S^ltwf.doc/gf, the independent color The adjustment has been achieved. If the requirements are not met, the user performs the step-cutting again, and the desired adjustment effect is positive. > The above-mentioned gamut matching and independent color-matching saturation matching correspondence table can be designed to be shared-Jingsi The invention is also designed to have respective correspondence tables.

In the above embodiment, the color conversion is relatively simple, and the feasibility of the hardware device is high, and the adjustment effect is good. The embodiment of the invention is based on the independent color adjustment hue difference correspondence table and the multi-color phase saturation matching correspondence table digital color adjustment method to achieve the best and consistent output of the display, and proposes a hardware device capable of realizing the color adjustment method. The invention has been disclosed in the above preferred embodiments. However, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention.
