Apparatus for compensating for gray component of image signal

Provided is an apparatus for compensating for a gray component of an input image signal. The apparatus detects a pattern of the input image signal and compensates for the gray component by substituting each channel value of the input image signal by a median value if it is determined that the input...

Zusammenfassung:Provided is an apparatus for compensating for a gray component of an input image signal. The apparatus detects a pattern of the input image signal and compensates for the gray component by substituting each channel value of the input image signal by a median value if it is determined that the input image signal is gray pattern. Accordingly, a problem of displaying a color component due to distortion of a gray component of an input image signal can be resolved by resolving a color recognition problem of a gray signal generated by channel differences of the input image signal due to noise induced by a display system, which receives an output of an ADC, or external influences.
