摘要
A contour emphasizing circuit and a contour emphasizing method, in which an image having sharpness and a clear image can be obtained, are provided. The contour emphasizing circuit provides a contour emphasizing signal generating means which outputs a delayed video signal, a contour emphasizing signal, and a plurality of differential signals by processing an inputted video signal, a signal level difference detecting means to which the plurality of differential signals outputted from the contour emphasizing signal generating means are inputted and which outputs a signal selecting control signal, and a signal selecting means to which the delayed video signal, the contour emphasizing signal, and the signal selecting control signal are inputted and which mixes the delayed video signal with the contour emphasizing signal in an arbitrary ratio and outputs a video output signal or which selects the delayed video signal or the contour emphasizing signal and outputs the selected signal as a video output signal.
