Image generating apparatus, image generating method, and program

Abstract

An image generating apparatus that can produce an image representing an unsteady object without involving an increased load of computing operations is provided. The image generating apparatus includes a control portion ( 11 ). The control portion ( 11 ) generates display image data to be displayed on a screen based on information on at least one three-dimensional object disposed in a three-dimensional space and information on a viewpoint position. Of the display image data, image area identification data identifying an image area corresponding to the three-dimensional object is stored in memory. Image defocusing processing is applied at least locally to the display image based on the image area identification data.
