Image generation apparatus, image generation method, and program

Abstract

A contrast sensitivity measurement apparatus () generates a stimulating image to be output to an external display device () for measuring contrast sensitivity of a user. An image scale setting unit () determines the spatial frequency in units of pixels on the basis of an observation distance, physical characteristics of the external display device (), and visual characteristics of a human. A carrier waveform generation unit () generates a luminance map in which a change of luminance along a first axis follows the spatial frequency. A contrast map generation unit () generates a contrast map in which contrast gradually decreases from one end to another end along a second axis, and an equal contrast line forms a given waveform. A stimulating image synthesis unit () generates the stimulating image by synthesizing the luminance map and the contrast map.
