ABSTRACT:
A pixel conversion apparatus includes a sync separator for separating a sync signal from an input signal, a pixel conversion information analyzer for analyzing how to convert the number of pixels to display the input signal as an image from the input signal and a picture display area, a timing signal generator for generating a timing signal for displaying an image according to the outputs of the sync separator and the pixel conversion information analyzer, a pixel converter for processing a pixel conversion of the input signal according to the output of the timing signal generator, an interpolator for processing a pixel interpolation when the pixel to be interpolated generated by pixel conversion at the pixel converter, and a sync signal generator for generating a sync signal for displaying the input signal as an image. Because the relation between the input signal and the image display area is previously analyzed and processed, there is no lack, or display by mistake, of image information included in the input signal and a high quality image can be effectively displayed on the picture display area of the display device.
