Abstract

A plurality of captured images is first acquired by capturing images of an object while changing a focal position along an optical axis. Then, variations in magnification among the captured images are acquired. On the basis of the variations in magnification, corresponding pixels in the captured images are specified, and definition is compared among the corresponding pixels. Then, an image reference value indicating the number of a captured image that is to be referenced as the luminance value of each coordinates in an omnifocal image is determined on the basis of the result of comparison of the definition. The omnifocal image is thereafter generated by referencing the luminance value in the captured image indicated by the image reference value for each coordinates. In this way, the omnifocal image that reflects the position and size of the object accurately can be generated.
