Image processing apparatus, image processing method, program, and camera

An image processing method that generates a joined image by joining a plurality of textures based on a plurality of images, the image processing method comprising:

• a motion vector derivation step of sequentially deriving motion vectors between images of the plurality of images;
• a cumulative error calculating step of calculating cumulative errors corresponding to misalignment between a position of a subject between a first image and a position of the subject in a second image, wherein the first image includes the subject, and wherein the second image includes the subject and is captured after the subject is out of field of view;
• a correction step of correcting the motion vectors between images included in a target section from a first image to a second image based on the cumulative errors and a number of frames in the target section;
• and
• a texture writing step of writing, into a frame memory, the plurality of textures that form the joined image, based on the motion vectors corrected in the correction step.

A non-transitory computer readable medium storing a program for causing a computer to execute image processing that generates a joined image by joining a plurality of textures based on a plurality of images, the image processing comprising:

• a motion vector derivation step of sequentially deriving motion vectors between images of the plurality of images;
• a cumulative error calculating step of calculating cumulative errors corresponding to a misalignment between a position of a subject between a first image and a position of the subject in the second image, wherein the first image includes the subject, and wherein the second image includes the subject and is captured after the subject is out of a field of view;
• a correction step of correcting the motion vectors between images included in a target section from the first image to the second image based on the cumulative errors and a number of frames in the target section;
• and
• a texture writing step of writing, into a frame memory, the plurality of textures that form the joined image, based on the motion vector corrected in the correction step.
