Claim Text:
1. An imaging apparatus, comprising: an imaging unit configured to capture two images that are different from each other by a predetermined amount of an optical distance (focus) between an objective lens and an imaging device having a first resolution; an angle-of-view adjustment unit configured to equalize angles of view of the two images, one of the two images being a first focus image and the other image being a second focus image; a diffusion unit configured to generate, as a digital defocused image, an image obtained by diffusing and enlarging the first focus image to have a second resolution higher than the first resolution; an upsampling unit configured to generate, as an enlarged defocused image, an image obtained by upsampling the second focus image to have the second resolution; and a difference calculation unit configured to generate, as an interference image, a difference for each pixel between the digital defocused image and the enlarged defocused image; and a transmission unit configured to transmit the first focus image and the interference image.
