Abstract
A cross color suppressing apparatus used for suppressing the cross color of a frame is provided. The frame has several pixels, and the image data of each pixel include a luminance and a chrominance. The apparatus includes a diagonal edge detector, a cross color detector and a chrominance suppressing unit. The diagonal edge detector is used for determining whether target pixel is on a diagonal edge according to the luminance of the target pixel and that of its neighboring pixels. The cross color detector is used for determining whether the chrominance of the target pixel is substantially different from that of its neighboring pixels. If both the determination results of the diagonal edge detector and the cross color detector are true, the chrominance suppressing unit suppresses the chrominance of the target pixel and its neighboring pixels.
