Abstract:
1. An image display method for use in an image display unit including an active matrix type display panel, comprising: writing a video signal having a first vertical frequency into an image memory at a first speed; reading the video signal as image data from the image memory at a second speed 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 speed; detecting a motion vector by using the image data read from the image memory; performing motion compensation interpolation by using the image data read from the image memory and the motion vector so as to generate respective image data each being a video signal having a second vertical frequency which is m/n-fold of the first vertical frequency and shifted as much as one frame from the other; emphasizing a high-zone component in a direction of the time base by using the output respective image data corresponding to at least two adjacent frames in the video signal having the second vertical frequency; and displaying the video signal having the second vertical frequency and the emphasized high-zone component in the direction of the time base on the active matrix type display panel.
