Half pixel interpolator for video motion estimation accelerator |
摘要 |
Methods and an apparatus are provided for interpolation of pixels in a pixel array having rows and columns of pixels. The apparatus includes a shift register array to shift pixel values of the pixel array, the shift register array including two or more shift registers; an interpolation filter array interconnected to the shift register array, the interpolation filter array including one or more interpolation filters; and a controller configured to provide pixel values in columns of the pixel array from the shift register array to respective interpolation filters in a first mode and configured to provide pixel values in rows of the pixel array from the shift register array to respective interpolation filters in a second mode. The controller may be configured to supply vertical sub-pixel values from the shift register array to the interpolation filters to generate diagonal sub-pixel values.
