Abstract
An image processing apparatus and an image processing method. The image processing apparatus includes a first convolution unit, a weight generator, a second convolution unit, an arithmetic unit and an outputting unit. The first convolution unit performs a convolution to output edge strength according to an original image signal and a high pass filter mask. The weight generator chooses a weight coefficient according to the edge strength. The second convolution unit performs a convolution to output an unsharp image signal according to the original image signal and a low pass filter mask. The arithmetic unit outputs a first sharpening signal according to the original image signal, the unsharp image signal and the weight coefficient. The outputting unit outputs a processed image signal according to the original image signal and the first sharpening signal.
