Image processing apparatus, image processing method, and program

An image processing method comprising:

• generating, with an image generation circuitry, a first reduced image by reducing one of a plurality of first images;
• dividing, with the image generation circuitry, the first reduced image into blocks;
• generating, with the image generation circuitry, a first reference image regarding a first imaging region on a basis of the blocks of the first reduced image generating, with the image generation circuitry, a second reduced image by reducing one of a plurality of second images;
• dividing, with the image generation circuitry, the second reduced image into blocks;
• generating, with the image generation circuitry, a second reference image regarding a second imaging region at least partially overlapping with the first imaging region on a basis of the blocks of the second reduced image;
• and generating, with a processor, positioning information indicating a correspondence between the first imaging region and the second imaging region on a basis of the first reference image and the second reference image.

A non-transitory computer readable medium storing a program for image processing, the program, when executed by an electronic processor, causes the electronic processor to perform a set of operations comprising:

• generating a first reduced image by reducing one of a plurality of first images;
• dividing the first reduced image into blocks;
• generating a first reference image regarding a first imaging region on a basis of the blocks of the first reduced image;
• generating a second reduced image by reducing one of a plurality of second images;
• dividing the second reduced image into blocks;
• generating a second reference image regarding a second imaging region at least partially overlapping with the first imaging region on a basis of the blocks of the second reduced image;
• and generating positioning information indicating a correspondence between the first imaging region and the second imaging region on a basis of the first reference image and the second reference image.
