Abstract

By taking into account the individual positions of the sub-pixels (108-118) on a color matrix display device (100), the apparent resolution can be increased. Sub-pixel sampling to determine samples at the correct position is incorporated in the image scaling filter (502). The filter response is such that the useful resolution inherent in the color matrix display device (100) can be used. In the filter design, a trade-off is made between sharpness and color errors. The scaling (216) is performed on e.g. a YUV signal, thereby saving bandwidth. The luminance signal Y is e.g. sub-sampled at high sub-pixel resolution, and the U and V components at pixel resolution. The sub-pixel positions are then taken into account in the YUV to RGB conversion (218).
