Step S24, described motion control submodule is controlled slide head by default mobile ordinal shift, color sensor probe is stopped successively and the different color information at the different coordinate positions of acquisition and recording places, until complete the information gathering at the individual coordinate position of (M+1) * (N+1) place;
Step S25, repeated execution of steps S21;
Step S26, described picture control submodule control and treat the revisal multi-screen display equipment by the picture of the lower a kind of color of default color sequences projection, and repeated execution of steps S23-step S25, until treat that the revisal multi-screen display equipment has throwed all colours picture;
Step S27, described color analysis module is according to the color information in the shared information and data storehouse, and analysis and arrangement obtains at the corresponding augmenting factor in the individual coordinate position of (M+1) * (N+1) place without the color picture;
Wherein, described default color sequences is followed successively by pure red, pure green, ethereal blue, pure white order; Described default mobile order for from the described origin of coordinates from left to right, order from top to bottom; Described Preset Time is 5 seconds.
