In one example, when processor obtains merging image for merging multiple first images, processor is actually executed
It operates below: choosing two first images, a first image is as benchmark member image, and another first image is as member figure to be matched
Picture；Benchmark member image is divided into multiple block images, and chooses a block image as reference block image from multiple block images；
The match block image with reference block images match is found in first image to be matched to form matching image pair；Circulation executes above-mentioned
Partiting step and above-mentioned searching step obtain multiple matching images pair to traverse multiple block images in benchmark member image；Fusion
The reference block image and match block image of each matching image centering obtain fused subimage, and splice multiple fused subimages with

00 with region P2~00 do correlation calculations, with judge region P2~00 whether be and the matched matching of reference block image P1-00
Block image, if correlation is greater than predetermined correlation, it is determined that region P2~00 is and the matched matching of reference block image P1-00
Block image, and make marks to region P2~00 and do image co-registration so as to subsequent；Conversely, then in first image P2 to be matched, with area
Domain P2~00 is starting point, mobile big with reference block image P1-00 according to predetermined moving step pitch to the direction x and/or the direction y
Small identical rectangle frame, rectangle frame of every movement, rectangle frame outline the region come and are required to do with reference block image P1-00
Correlation calculations, with judge rectangle frame outline come region whether be with the matched match block image of reference block image P1-00,
If rectangle frame outline come region be with the matched match block image of reference block image P1-00, to rectangle frame outline come
Region make marks, otherwise, rectangle frame continues to move to, until traversal whole first image P2.As shown in figure 16, due to output
The visual field difference of the photosensitive pixel set of benchmark member image P1 and the photosensitive pixel set of output first image P2 to be matched, reference block
Image P1-00 can not find matched match block image in first image P2 to be matched, equally export images match at this time
It is right, but images match centering only includes reference block image P1-00.
After the match block image for having found reference block image P1-00, reference block image P1-00 is changed to block by processor
Image P1-01, and find and the matched match block image of reference block image P1-01 in a manner mentioned above.As shown in figure 16, with
