Abstract
A method of reducing color smearing or color artifacts in a low resolution picture that is subjected to chrominance downsampling prior to display on a display device first upsamples the pixels in each row of the picture to double the picture width, then downsamples the chrominance values to produce a compressed data stream for transmission to the display device, and finally decompresses the compressed data stream for display. In order to maintain the aspect ration of the original picture, each doubled row may be repeated prior to transmission to the display device.
