Implementations include video image processing systems, methods, and apparatus for downscaling video data using a phase control multi-tap downscale filter. For example, a device configured to process video information may include a memory configured to store a downscaling filter comprising a number of coefficients. A processor may be configured to receive video input data and determine a scale factor between the video input data and a video output. In addition, the processor may be configured to modify the downscaling filter based on the scale factor and the number of coefficients in the unmodified downscaling filter. The processor may be configured to downscale the video input data using the modified downscaling filter. |
