Abstract:
1. An image display unit using an active matrix type display panel which has a plurality of pixels arranged in a matrix form, and holds and displays an electrical signal pixel by pixel for a predetermined time, comprising: a rate conversion circuit which converts a video signal having a first vertical frequency into a video signal having a second vertical frequency which is m/n-fold (wherein m is an integer of 2 or more, n is an integer of 1 or more, and conditions of m>n are satisfied) of the first vertical frequency, and outputs the converted signal; a time base emphasizing circuit which emphasizes a high-zone component in a direction of the time base by using image data corresponding to at least two adjacent frames in the video signal having the second vertical frequency output from the rate conversion circuit; and a drive circuit which displays the video signal having the second vertical frequency output from the rate conversion circuit in the active matrix type display panel, wherein the rate conversion circuit comprises:
