Image processing device, non-transitory computer-readable medium, and image processing method

A non-transitory computer-readable medium storing an image processing program causing a computer to function as:

• a first processing unit, detecting corresponding pixels between reference image data selected from among a plurality of pieces of raw image data and each of a plurality of pieces of comparison image data comprised in the plurality of pieces of raw image data, synthesizing the reference image data and the plurality of pieces of comparison image data on the basis of the corresponding pixels, and generating synthesized raw image data;
• a map generation unit, generating map information in which a pixel position of the synthesized raw image data is associated with information derived from at least one piece of raw image data of the plurality of pieces of raw image data;
• and
• a second processing unit, executing image processing different from that of the first processing unit on the synthesized raw image data that has been demosaiced, on the basis of the map information generated by the map generation unit.

An image processing method comprising:

• a first processing step of detecting corresponding pixels between reference image data selected from among a plurality of pieces of raw image data and each of a plurality of pieces of comparison image data comprised in the plurality of pieces of raw image data, synthesizing the reference image data and the plurality of pieces of comparison image data on the basis of the corresponding pixels, and generating synthesized raw image data;
• a map generation step of generating map information in which a pixel position of the synthesized raw image data is associated with information derived from at least one piece of raw image data of the plurality of pieces of raw image data;
• and
• a second processing step of executing image processing different from the image processing in the first processing step on the synthesized raw image data that has been demosaiced, on the basis of the map information generated by the map generation step.
