Abstract
An image processing method and an image processing apparatus are provided. After receiving an image signal, the image and apparatus according to the invention first judge whether a target block in the image signal includes a non-chroma line. If the judging result is YES, a first edge detection procedure will be performed on the non-chroma line. If the judging result is NO, a second edge detection procedure will be performed on the target block.
Claims7
An image processing method for processing an image signal, comprising the steps of:
- (a) receiving the image signal;
- (b) judging whether a target block in the image signal comprises a non-chroma line;
- and
- (c) if the judging result of step (b) is YES, performing a first edge detecting procedure on the non-chroma line and selectively performing a second edge detecting procedure on the target block except the non-chroma line;
- if the judging result of step (b) is NO, performing the second edge detecting procedure on the target block.
