Document Type and Number:
Japanese Patent JP2001520781
Kind Code:
A
Abstract:
In a motion or depth estimation method, a set (CS) of candidate motion vectors, or depth values formed by already obtained motion vectors, or depth values for neighboring image parts which are spatio-temporally adjacent to a given image part of interest, is generated (MV-MEM) for the given image part of interest. Those candidate motion vectors or depth values which correspond to neighboring image parts containing more reliable texture information than other neighboring image parts, are prioritized (TBPD) to obtain a prioritized set (PCS) of candidate motion vectors or depth values. Thereafter, motion or depth data (MV) for the given image part of interest is furnished (ME) in dependence upon the prioritized set (PCS) of candidate motion vectors or depth values. Finally, an image signal processing device (ISPD) processes an image signal (Iin) to obtain an enhanced image signal in dependence upon the motion or depth data (MV).
