An
image processing apparatus, an
image processing method, and an
image processing program are provided. The
processing apparatus, method, and program relate to image
processing executed in an AF camera, etc., and make clear a variation in an image displayed during focusing operation. The image
processing apparatus includes an image-capturing element that puts out an image formed through an optical
system, a focus controlling unit that controls the optical
system to locate it at a focusing position, using the image obtained by the image-capturing element through the optical
system, and an image processing unit that forms a pseudo-image during focusing operation of the optical system caused by the focus controlling unit, the pseudo-image showing a resolution variation enlarged to be greater than that of the image obtained by the image-capturing element.
