Description of drawings
Fig. 1 is a system block diagrams, but a preferred embodiment of the display device of the present invention's automatic color regulating is described;
Fig. 2 is a MSDS, and a grouped data of this preferred embodiment is described;
Fig. 3 is a process flow diagram, and the step of the automatic color regulating method of display device of the present invention is described.
Embodiment
The present invention is described in detail below in conjunction with drawings and Examples.
Consult Fig. 1 and Fig. 2, but the preferred embodiment of the display device 1 of the present invention's automatic color regulating comprises a storage element 11, a processing unit 12 and a display unit 13.
The automatic color regulating method that coordinates flowchart text the present embodiment display device 1 shown in Figure 3 to carry out is as follows:
Step 21: display device receives image signal.
The processing unit 12 of display device 1 receives the image signal of an input.
Step 22: the RGB that analyzes image signal forms.
The source code that processing unit 12 reads in storage element 11 forms with redness, green and the blue pixel of analyzing in the input image signal, and produces an analysis of data.
Step 23: read a grouped data with multiple image type.
Step 24: the RGB that sets according to each image type forms, the image type of judgement image signal.
The grouped data 111 that the analysis of data that processing unit 12 comparison steps 22 produce and step 23 read, according to redness, green and the blue pixel proportion of composing of input image signal, the image type of judgement image signal.
Step 25: in the default corrected parameter of grouped data, adjust the colour temperature of image output according to each image type.
The color temperature value that processing unit 12 is built at grouped data 111 in advance according to the image type of image signal is adjusted this image signal.
Step 26: in other default corrected parameter of grouped data, adjust Gamma value and the brightness value of image output according to each image type.
Step 27: image output.
Further illustrate as an example of image type " sky " example: processing unit 12 reads source code and produces an analysis of data to analyze the input image signal in redness, green and the blue pixel proportion of composing of display frame again.And post-processing unit 12 this analysis of data of comparison and grouped datas 111, in, green pixel the highest when R010 ratio in the red pixel of this analysis of data in the highest and blue pixel of G010 ratio the B250 ratio the highest, the image type that judges this image signal is sky, and adjust this image signal according to the corrected parameter of color temperature value (10000K), Gamma value (2.3) and the brightness value (210nit) of image type " sky ", and produce an output signal and be sent to display unit 13 to produce display frame.In addition, grouped data 111 can also have other image types, and the RGB of specific image type composition can be the color composition as the present embodiment, but the color that also can be set as other types forms, for example the judgment rule of red pixel setting originally is single color range R010, but also can set with the color stage interval as judgment rule, as R005-R020; In addition, the corrected parameter of specific image type also can be adjusted.Therefore, the implementation content of grouped data 111 should not be limited to the disclosed content of the present embodiment.
In sum, the grouped data table 111 that is stored in storage element 11 is built multiple image type in advance, and forms and corrected parameter corresponding to the RGB of described image type; Processing unit 12 coordinates source code and grouped data table 111 to input the image type of image signal and make corresponding image adjustment with automatic decision, make the user need not to carry out extra image adjustment action, and promote the convenience that uses, so but the display device of the present invention's automatic color regulating and automatic color regulating method thereof can be reached purpose of the present invention really.
The above is only preferred embodiment of the present invention, and when not limiting scope of the invention process with this, i.e. all simple equivalences of doing according to claims of the present invention and instructions change and modify, and all still belong to the scope that the present invention is contained.
