Motion image compensation method and device, display device

A moving image compensation device, comprising:

• a first acquisition module for acquiring a first image corresponding to pre-motion picture and a second image corresponding to post-motion picture;
• a division module for dividing the first image and second image obtained by the first acquisition module into a number of image blocks respectively, in which image blocks in the first image and image blocks in the second image are in one-to-one correspondence;
• a first calculation module for performing calculating any pair of image blocks corresponding to each other in the first image and the second image by the division module based on phase plane correlation method and obtaining at least one displacement vectors with a phase correlation degree greater than a preset threshold;
• an edge detection module for subjecting the first image and the second image obtained by the first acquisition module to edge detection respectively to obtain edge feature patterns in the pair of image blocks corresponding to each other;
• and
• a second acquisition module for acquiring a displacement vector that matches a transformation between edge feature patterns in the pair of image blocks corresponding to each other from the at least one displacement vector obtained by the first calculation module as a displacement vector corresponding to the pair of image blocks in a motion compensation process.

A moving image compensation device, comprising:

• one or more processors;
• and
• a storage medium storing computer readable operation instructions;
• while the instructions are executed, the processor is caused to carry out steps of:
• acquiring a first image corresponding to a pre-motion picture and a second image corresponding to a post-motion picture;
• dividing the first image and the second image into a number of image blocks respectively, the image blocks in the first image and the image blocks in the second image being in one-to-one correspondence;
• performing calculation on any pair of image blocks corresponding to each other in the first image and the second image based on a phase plane correlation method to obtain at least one displacement vector with a phase correlation degree greater than a preset threshold;
• subjecting the first image and the second image to edge detection respectively to obtain edge feature patterns of the pair of image blocks corresponding to each other;
• and
• acquiring a displacement vector that matches a transformation between edge feature patterns in the pair of image blocks corresponding to each other from the at least one displacement vector as a displacement vector corresponding to the pair of image blocks in a motion compensation process.
