Abstract: An apparatus for processing an image signal prevents burn-in of display devices such as a PDP and an LCD. A number-of-pixels conversion section generates pixel data located at interpolation positions in horizontal or vertical directions based on information about the interpolation positions obtained from a controller, to obtain an image signal in which the number of pixels is converted. A panel driver shifts the display position of an image in a PDP in the horizontal or vertical directions by as much as one pixel, each time a predetermined period of time elapses, within a predetermined range based on information about the display position obtained from the controller in order to prevent a screen from being burned-in. The controller changes the phase of each of the interpolation positions in a change unit smaller than 360° for a period of time when the display position of the image is shifted by as much as one pixel, the interval between the interpolation positions being set to 360°.

Abstract: A double-rate signal achieved by subjecting a video signal to double-rate conversion is supplied to a scan line number converter. In the converter, the portion of the effective scan lines of the double-rate signal is written into a frame memory on the basis of a signal achieved by multiplying horizontal and vertical synchronous signals based on the double-rate signal. In the effective scan line section of HDTV signal, the video signal written in the frame memory is read out on the basis of horizontal and vertical reference signals based on the HDTV signal.

Accordingly, the HDTV signal suffers no degradation because the video signal in the section of 960 effective scan lines of the double-rate signal is not interpolated.
