Image processing apparatus, image pickup apparatus, image processing method, and computer program

An image processing method comprising the steps of:

• transforming, on the basis of transformation information concerning a first picked-up image forming a picked-up moving image picked up by an image pickup apparatus and a second picked-up image forming the picked-up moving image located after the first picked-up image on a time axis of the picked-up moving image, the second picked-up image;
• and
• causing a second image storing unit different from a first image storing unit, which stores a first history image including the first picked-up image, to store the transformed second picked-up image, overwriting the first history image stored in the first image storing unit on the second picked-up image stored in the second image storing unit, and combining the first history image and the second picked-up image.

A computer program for causing a computer to execute:

• an image transforming procedure for transforming, on the basis of transformation information concerning a first picked-up image forming a picked-up moving image picked up by an image pickup apparatus and a second picked-up image forming the picked-up moving image located after the first picked-up image on a time axis of the picked-up moving image, the second picked-up image;
• and
• an image combining procedure for causing a second image storing unit different from a first image storing unit, which stores a first history image including the first picked-up image, to store the transformed second picked-up image, overwriting the first history image stored in the first image storing unit on the second picked-up image stored in the second image storing unit, and combining the first history image and the second picked-up image.
