Then next pixel is made the processing of above-mentioned steps, passed through judgement and output thus, on auspicious image, can see in the process window of different disposal and the image outside the window each pixel of an auspicious image.
Embodiment 2
Store the parameter information of area, shape, movement velocity, movement locus and the window border color of contrast window in the dynamic contrast controlled variable memory circuit, also can dispose by universal serial bus, as shown in Figure 5, be the process flow diagram of image processing effect dynamic contrast display packing embodiment 2 of the present invention.
The parameter information of area, shape, movement velocity, movement locus and the window border color of the contrast window that step 301, dynamic contrast controlled variable storage circuit  store, it is circular setting window shape, radius is 200 pixels, movement velocity is per 5 and moves a pixel, sends and window track counting circuit and window profile counting circuit;
Step 302, window track counting circuit are according to the row of display device and the movement velocity and the particular location of motion track information calculation window center of gravity on display screen of field information and window, center of gravity (center of circle) initial coordinate is (500,500), circle moves with miter angle, the coordinate  of center of gravity becomes (501,501) the 5th the time so;
The relative distance that step 303, window profile counting circuit calculate window profile and widget gravity according to the parameter information and the particular location of above-mentioned widget gravity on display screen of above-mentioned window area and shape, the relative distance of window profile and widget gravity is 200 pixels in the present embodiment;
Step 304, raw image data one tunnel enter decision circuit through the video in window processing circuit processes, to image process color in the window, brightness, the enhancing of contrast processor, another road of raw image data enters the outer image processing circuit of window and enters decision circuit through handling, but without the processing of any processor; Image processing circuit is just exported through color in the window so, brightness, and the view data that contrast strengthens, and the outer image processing circuit output of window is without the raw image data of processing;
Step 305, current pixel point position calculation circuit calculate row and its particular location at current line at current display pixel point place, and current central coordinate of circle is (500,500).Carry out accumulated counts from current display field initial time begin column counter and row interior pixel point counter, determine the coordinate of current pixel point, when handling coordinate is (400, during 416) pixel, the current pixel point position calculation circuit is (400 according to the coordinate that picture element coordinate and round shape data calculate the intersection point of extension in the horizontal direction of this pixel and circle outer rim, 400) and (400,517);
Step 306, decision circuit are according to the particular location (400 of current pixel, 416) and the particular location of window, central coordinate of circle is (500,500), and the extension in the horizontal direction of this pixel is (400 with the coordinate of the intersection point of circle outer rim, 400) and (400,517), comparator circuit draws 400<416<517 result, therefore can judge that this pixel is positioned at window, so execution in step 307, otherwise execution in step 308;
The signal that step 307, decision circuit output are exported through the video in window treatment circuit;
The signal that step 308, decision circuit output are exported through the outer image processing circuit of window.
Successively each pixel is made the processing of above-mentioned steps thus, the color of image in window thus, brightness, contrast has all obtained tangible improvement.And the outer image of window is an original image.
And because the image processor in the video in window treatment circuit can be various processors, as border enhancement process device, color space transformation processor or color transition processor or the like, therefore, the image that shows from window can pass through various processing, or the stack of various processing, or without processing.In like manner, the outer image processing circuit of window also can comprise color processor, luminance processor, contrast processor, color space transformation processor or color transition processor or the like, can certainly be without processing, the outer image of window also can be the image after handling through the different processing of these processors or wherein some thus.Therefore, can be very flexibly and various, need in the window and window contrasts and shows which kind of is just handled and can control and select by controlling selector switch outward.And owing to window can move and transform size, so display effect is very good.As shown in Figure 6.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
