Abstract
According to the aspect of the present invention, an image processing device capable of absolutely removing noises in each frame forming a live image can be provided. Specifically, according to the aspect of the present invention, a target block T can be set in the original image It and it is searched out where such target block T is imaged in the superimposition target image Ot−1. According to the aspect of the present invention, a tracking of the subject image is executed per block, so that reliability thereof can be extraordinarily improved compared to the conventional method searching the destination every individual pixel.
Claims19
An image processing device for processing a sequence of images, the images including a reference image and an original image, the reference image being captured prior to the original image, the device comprising a processor configured to:
- set a target block in the original image, the target block including an attention pixel and periphery pixels of said attention pixel among pixels;
- search out a destination block most resembling said target block in the reference image;
- generate a fusion block by superimposing a superimposition target block in a superimposition target image to the target block in the original image, the superimposition target image acquired through a noise reduction of the reference image;
- and
- generate a noise reduction image having reduced noises being imaged in said original image by superimposing a plurality of respective said fusion blocks in the original image one after the other along with setting a plurality of respective said target blocks one after the other while changing a location of the attention pixel so that the location of the fusion block is the same as the location of the target block in the original image.
