Method for vertical imaging scaling |
摘要 |
A method for operating a scan-line video processor that allows for vertical scaling with no additional memory in a display system and extracts more SVP instructions in vertical down scaling applications. The input and output sync periods of the SVP (16) are controlled such that the SVP (16) produces output lines of interpolated data that is a vertical scaling factor of the input lines. The data is then sent to a memory (24) to correct for centering and time base changes in the interpolated data. Finally, the data is sent to a display device, such as a CRT or a spatial light modulator.
