A REAL-TIME COLOR CORRECTION CIRCUIT BASED ON 2-DIMENSIONAL CHROMATICITY REGION SEPARATION

In general, the reproduced colors on a TV screen are not exactly the s ame as the colors of original images transmitted from a TV station bec ause color signals are distorted due to internal and external factors of a TV system. In this paper, we have developed a real time color cor rection circuit using calorimetric color processing technique, which i s based on 2-dimensional chromaticity region separation. In addition, a preference color processing technique is also used. This circuit has been modeled in VHDL, implemented in an 130,000 gate chip, and applie d to TV systems.
