A high frequency component detection circuit detecting a high frequency component included in a video signal is provided. The high frequency component detection circuit includes a filter acquiring a group of a predetermined number of pixels including a focused pixel and pixels surrounding the focused pixel with respect to each of pixels constituting the video signal, rearranging the pixels constituting the group to be arrayed in the order of luminance values, determining the luminance value of the pixel positioned at the center in the rearranged order, and outputting the pixel positioned at the center among the rearranged pixels arrayed in the order of luminance values as the focused pixel. Further, the high frequency component detection circuit includes a detection circuit detecting a high frequency component included in the video signal based on the output from the filter.
