In the present embodiment, directly adjust Video processing parameter in the register module 142 in the LCOS display chip by microcontroller, can handle vision signal, thereby brightness, contrast and the saturation of the video image of adjustment output have reached the purpose that strengthens the video image display effect.And owing to directly adjust by the LCOS display chip, do not need to increase extra image effect and adjust circuit, reduced power consumption.
As shown in Figure 2, in one embodiment, this system also comprises:
Input modular converter 130 is used for receiving video signals, and whether the form that detects vision signal be component video signal form (YCbCr), if then vision signal is directly exported to signal processing module 141; If not, export to signal processing module 141 after then vision signal being converted into the component video signal form.Such as, if vision signal is rgb format, vision signal can be converted into the YcbCr form and exports to signal processing module 141 again.Be understandable that though input modular converter 130 is not integrated in the LCOS display chip among Fig. 2, this input modular converter 130 can be integrated in the LCOS display chip.In the present embodiment, by adding input modular converter 130, make the vision signal that this system can compatible other form, and handle.
In one embodiment, signal processing module 141 also is used for, the processed video signal is exported to before the image-forming module 143, whether the value of the component information in the check processed video signal is in preset range, when surpassing preset range, the value of the component information in the processed video signal is limited within the preset range.Preset range can be [0,255], such as, the value of supposing the component information in the processed video signal is M, then when detecting M less than 0 the time, M is defined as 0; When detecting M greater than 255 the time, then M is defined as 255.In the present embodiment, by the scope of detected value, the value that exceeds preset range is limited, thereby guaranteed the validity of the vision signal of signal processing module 141 outputs.
In one embodiment, the Video processing parameter comprises luminance parameter, the component information in the vision signal is handled comprise:
To the luminance component in the vision signal according to following formula manipulation:
Formula 1:Y_OUT=Y_IN+BRI,
Wherein, Y_IN is the luminance component in the vision signal that receives of signal processing module 141, and BRI is luminance parameter, and Y_OUT is the luminance component in the processed video signal.The span of BRI is [255,255].
In one embodiment, above-mentioned formula 1 can be realized by an adder in the LCOS chip.
In the present embodiment, BRI be on the occasion of the time, brightness strengthens, when BRI is negative value, brightness deterioration, thus realize adjustment to the brightness of vision signal.
In one embodiment, the Video processing parameter comprises contrast level parameter and brightness median, and the luminance component in 141 pairs of vision signals of signal processing module is handled according to following formula:
Formula 2:Y_OUT=K ' * (Y_IN-Y_MID)+Y_IN,

Contrast reflection be the bright difference degree between dark of same video image in the vision signal, above-mentioned formula 2 is derived, then
Y_OUT=（K’+1）*（Y_IN-Y_MID)+Y_MID，
Be Y_OUT-Y_MID=(K '+1) * (Y_IN-Y_MID), suppose K=K '+1, with reference to figure 3, it is the schematic diagram of handling the luminance component of vision signal among the embodiment based on the video signal processing system of LCOS display chip, Y_IN-Y_MID is abscissa, Y_OUT-Y_MID is ordinate, and 255-Y_MID is the maximum of horizontal ordinate, and Y_MID-255 is the minimum value of horizontal ordinate.Work as K=1, i.e. K '=0 o'clock, input A1, output A1, it is constant to handle the back luminance component, i.e. Y_OUT=Y_IN; When 0＜K＜1, namely-1＜K '＜0 o'clock, for abscissa A1, if brightness is input as Y_IN, this moment A1=Y_IN-Y_MID 0 o'clock, corresponding ordinate is A2, A2=Y_OUT-Y_MID because A2＜A1, then Y_OUT＜Y_IN handles the back luminance component and reduces; For abscissa-A1, if brightness is input as Y_IN ', at this moment-A1=Y_IN '-Y_MID＜0 o'clock, ordinate be-A2-A2=Y_OUT '-Y_MID, and A2＜A1, i.e. Y_OUT '〉Y_IN ', handle the back luminance component and become greatly; This shows, when 0＜K＜1, namely-1＜K '＜0 o'clock, for same the picture of vision signal, can make that those luminance components greater than Y_MID diminish, become big less than those luminance components of Y_MID, same picture brightness component difference reduces, thereby makes contrast reduce; When K＞1, i.e. K '＞0 o'clock because A3＞A1 for same picture, then can make those luminance components greater than Y_MID become big, diminishes less than those luminance components of Y_MID, and same picture brightness component difference becomes big, and contrast increases.Preferably, the span of K ' can be (1,1).
As shown in Figure 4, it is the schematic diagram of handling the luminance component of vision signal among the embodiment based on the video signal processing system of LCOS display chip.In the LCOS display chip, above-mentioned formula 1 and formula 2 can be realized by a subtracter, a multiplier and two adders:
The luminance component Y_IN of input is by adder 1 and luminance parameter BRI addition, and output Y_ADD1 has realized the adjustment to the brightness of vision signal.Deduct median Y_MID by subtracter 1 then, output Y_SUB=Y_ADD1-Y_MID; Multiply each other with contrast level parameter K ' by multiplier 1, output Y_MUL=K ' (Y_ADD1-Y_MID) again; Again by the adder 4 luminance component Y_IN addition with input, output Y_ADD2=K ' (Y_ADD1-Y_MID)+Y_IN, Y_ADD2 namely is the luminance component after vision signal is handled, and adjusts when realizing the brightness and contrast to vision signal.Can pass through comparator 1 again, whether the value of judging Y_ADD2 within [0,255], is then directly to export Y_OUT, is not then it to be limited to export Y_OUT within [0,255] again.
In the present embodiment, revise contrast level parameter and brightness median by microcontroller, can be to the luminance component in the vision signal be handled, thus adjust the contrast of vision signal, reach the purpose that strengthens the video image display effect.
In one embodiment, chroma blue component and the red color component in 141 pairs of vision signals of signal processing module handled according to following formula respectively:

Formula 4:Cr_OUT=K ' * (Cr_IN-128)+Cr_IN, wherein, Cr_IN is the red color component in the vision signal of importing in the signal processing module 141, Cb_OUT is the red color component in the processed video signal.
Owing to separately brightness is handled, may produce the phenomenon of chroma offset, therefore, in the present embodiment, luminance component, chroma blue component and red color component are all adjusted, thereby can more preferably adjust the contrast of vision signal, reach the purpose that strengthens the video image display effect.
In one embodiment, the Video processing parameter comprises first saturation parameters and second saturation parameters, and red color component and chroma blue component in 141 pairs of vision signals of signal processing module are handled according to following formula respectively:

Saturation reflection be that color departs from the degree with the brightness grey, so saturation depends on the ratio that contains colour content and colour killing composition (grey) in same the video image of vision signal, it is more big to contain colour content, saturation is more big; The colour killing composition is more big, and saturation is more little.And chroma blue component and red color component are to contain colour content, and luminance component is colour killing composition (grey).Above-mentioned formula 5 is out of shape:
Cb_OUT-128=（K1’+1）*（Cb_IN-128)，
