Abstract:
An image processing apparatus includes an image acquisition unit configured to acquire a first image and a second image taken at a different focus position from the first image, an image magnification calculator configured to calculate a first image magnification of an object in the first image and a second image magnification of the object in the second image, an image size changer configured to change an image size of at least one of the first and second images so as to reduce a difference between the first and second image magnifications that are calculated by the image magnification calculator, according to the difference between the first and second image magnifications, and a processor configured to perform a calculation using the first and second images after the image size is changed by the image size changer.
