Sharpness improving system for picture processor
专利汇可以提供Sharpness improving system for picture processor专利检索，专利查询，专利分析的服务。并且PURPOSE: To prevent a character from being made thick and to reproduce the character with high quality by extracting an edge signal from a picture signal, and correcting a color signal required for a hue identification means.
CONSTITUTION: The system is so constituted that a correction means 5 is pro vided to extract an edge signal from a picture signal and to correct a color signal required for a hue identification means 3. When a character with a hue such as W, Y, M, C, B, G, R, K is included in a picture, the hue identification means 3 detects the hue and a high pass filter 2 detects the edge of the charac ter and an edge detection signal corrects a color signal required for the hue identification means 3. Thus, even when an original picture signal is unsharpened, the required color signal whose edge is sharp is obtained thereby preventing the character from being made thick.
