Photic image processing method

A photic image processing method, comprising steps of:

• (1) processing a photic image unit to generate a photic image signal having a plurality of basic image signals;
• (2) performing a first regulating compensation to each of said basic image signals of said photic image to generate a first compensated basic image signals in order to equilibrate said basic image signals of said photic image signal;
• (3) multiplexing said first compensated basic image signals in a period of time to generate a multiplexed photic image signal having said compensated basic image signals in series in said period of time, wherein said period is equal to a time of processing a photic image unit;
• (3a) equally dividing said period of time into three segments, and multiplexing said 3 basic signals of red, green and blue fundamental colors in said three segments to obtain a multiplexed photic image signal alternately containing therein said 3 basic signals;
• (3b) outputting three compensation values at said three segments, each of said three compensation values compensating one of said 3 basic signals of red, green and blue fundamental colors at the corresponding segment in said multiplexed photic image signal;
• (3c) compensating said 3 basic signals of red, green and blue fundamental colors in said multiplexed photic image signal by multiplying respectively said three compensation values therefor to accomplish said second regulating compensation;
• and
• (4) performing a second regulating compensation for said multiplexed photic image signal to generate a second compensated multiplexed photic image signal;
• wherein said basic image signals of said photic image signal are respectively 3 basic signals indicative of red, green and blue fundamental colors, where is executed by a photic image picking up circuit including a lamp having a brightness, a lens and charge coupled device (CCD), and wherein said first regulating compensation regulates and equilibrates said photic image signals of red, green and blue fundamental colors and compensates a lamp aping phenomenon of said photic image pick-up circuit.
