Patent ID: RE43161

Claim:
A photic image processing method executed by a photic image pick-up circuit including a lamp having a brightness, a lens and charge coupled device (CCD), the method comprising steps of : (1) processing a photic image unit to generate a photic image signal having a plurality of basic image signals each of which represents , individual signals representing a fundamental color, wherein said the basic image signals of said the photic image signal are respectively 3 three basic signals indicative of red, green and blue fundamental colors; (2) performing a first regulating compensation to each of said the basic image signals of said the photic image signal to generate first compensated basic image signals, wherein said the first regulating compensation regulates and equilibrates said the photic image signals of red, green and blue fundamental colors and compensates a lamp aging phenomenon of said the photic image pick-up circuit; (2a) eliminating a common-mode voltage of said the photic image signal; (2b) regulating a DC voltage offset of said the photic image signal; (2c) amplifying and outputting said the photic image signal whose said the DC voltage offset is regulated; (2d) performing said the first regulating compensation in response to a control signal, in order to equilibrate said the basic image signals of said the photic image signal; (3) multiplexing said the first compensated basic image signals in a period of time to generate a multiplexed photic image signal having said the first compensated basic image signals in series in said the period of time, wherein said the period is equal to a time of processing a photic image unit; and (4) performing a second regulating compensation for said the multiplexed photic image signal to generate a second compensated multiplexed photic image signal.
