Efficient spatio-temporal video up-scaling

A computer program comprising code stored on a computer-readable medium which, when executed by a computer, causes the computer to carry out the steps of:

• receiving an input video comprising a sequence of input frames,
• analyzing the input video to estimate motion vectors associated with the sequence of input frames, and determining corresponding motion compensation errors associated with the motion vectors;
• determining an extent to which computational resources are to be respectively allocated to spatially up-scaling the sequence of input frames and temporally up-scaling the sequence of input frames, based on the estimated motion vectors and corresponding motion compensation errors;
• and
• spatio-temporally up-scaling the sequence of input frames based on the determined extent.

A method of performing spatio-temporal up-scaling, comprising:

• receiving an input video data comprising a sequence of input frames;
• performing a combination of spatial up-scaling and temporal up-scaling to the sequence of input frames;
• and
• modifying the combination dynamically as a function of at least one property of the sequence of input frames.
