The present invention enables processing results which are more accurate and which have higher precision as to events of the real world to be obtained. (An inverse gamma correction unit 5001 applies inverse gamma correction to an input image wherein light signals of the actual world have been projected and a part of the continuity of the light signals of the actual world has been lost, and which has been subjected to gamma correction. A data continuity detecting unit 101 detects, in the input image subjected to inverse gamma correction, data continuity corresponding to the continuity of light signals of the real world. An actual world estimating unit 102 estimates the light signals by estimating the continuity of the light signals of the real world, based on the data continuity. An image generating unit 103 generates an output image from the estimated light signals. A presentation system property correcting unit 5002 applies correction corresponding to the properties of the presentation system to the output image that has been generated. The present invention can be applied to an image processing device for generating images with higher resolution.
