Apparatus and method for video processing

An apparatus for video processing comprising:

• a processing component configured to:
• determine, for a search block within a first frame, a relative location of a corresponding block in a second frame with respect to the search block based on comparative searching at a predetermined granularity to produce a motion vector for the search block with a first precision;
• determine correlation values with respect to the search block for the corresponding block and for at least one block defined at a relative location of less than the predetermined granularity with respect to the corresponding block;
• and
• determine a refined motion vector for the search block with a second higher precision based on the relative location of the block having a selected correlation value that is selected from among the correlation values with respect to the corresponding block and the at least one block,
• wherein the at least one block is produced by up-sampling the corresponding block at less than the predetermined granularity in different directions relative to the corresponding block to generate an alternating pattern of corresponding block pixels and oversampled pixels.

A non-transitory computer-readable storage medium storing a set of instructions for execution by one or more processors to facilitate manufacture of an integrated circuit that includes:

• a processing component configured to:
• determine, for a search block within a first frame, a relative location of a corresponding block in a second frame with respect to the search block based on comparative searching at a predetermined granularity to produce a motion vector for the search block with a first precision;
• determine correlation values with respect to the search block for the corresponding block and for at least one block defined at a relative location of less than the predetermined granularity with respect to the corresponding block;
• and
• determine a refined motion vector for the search block with a second higher precision based on the relative location of the block having a selected correlation value that is selected from among the correlation values with respect to the corresponding block and the at least one block,
• wherein the at least one block is produced by up-sampling the corresponding block at less than the predetermined granularity in different directions relative to the corresponding block to generate an alternating Pattern of corresponding block pixels and oversampled pixels.
