Image processing apparatus, method, and program

An image processing method comprising:

• acquiring an image group and information about an imaging position of images constituting the image group;
• performing a first composition process on the image group to generate a first composite image;
• determining whether a quality of the first composite image satisfies a first criterion;
• and
• performing, in a case in which the quality of the first composite image does not satisfy the first criterion, a second composition process on the image group or the first composite image based on the information about the imaging position to generate a second composite image.

A non-transitory, computer-readable tangible recording medium on which an image processing program is recorded, the image processing program causing a computer to implement:

• a function of acquiring an image group and information about an imaging position of images constituting the image group;
• a function of performing a first composition process on the image group to generate a first composite image;
• a function of determining whether a quality of the first composite image satisfies a first criterion;
• and
• a function of performing, in a case in which the quality of the first composite image does not satisfy the first criterion, a second composition process on the image group or the first composite image based on the information about the imaging position to generate a second composite image.
