Abstract
Provided are a digital video rescaling system, a method of rescaling video images, and a chip comprising a computer executable medium embedded therein computer executable instructions for rescaling video images.
Claims20
A digital video rescaling system comprising:
- an input module configured to receive an input image data;
- an adaptive spline interpolation kernel coupled to the input module, wherein the adaptive spline interpolation kernel is configured to generate an interpolated pixel based on the input image data;
- a sharpness control module coupled to the adaptive spline interpolation kernel, wherein the sharpness control module is configured to generate sharpness control parameters to control the adaptive spline interpolation kernel;
- and
- an overshoot control module coupled to the adaptive spline interpolation kernel, wherein the overshoot control module is configured to generate overshoot control parameters to control the adaptive spline interpolation kernel.
