It is an object to perform color correction that is simple and utilizes existing devices to achieve an increase in the feeling of depth in 2D images. Input image data are transformed into predetermined color information by a color information calculation portion 11. A correction amount control portion 10 determines a correction gain value for the color information according to depth information that has been input. A color information correction portion 12 performs color information correction based on the correction amount due to the contrast between the color information of a target pixel and representative color information of the surrounding region, and the correction gain value of the correction amount control portion. An output portion 13 converts this into a predetermined image format and outputs the result. Thus, by correcting the color information based on the contrast effect in conjunction with the depth information of the foreground and the background, for example, it is possible to easily increase the feeling of depth in a 2D image. Moreover, by controlling the color contrast effect with the depth information when performing the color correction, it becomes possible to more easily give a sense of depth that is perceived by humans.

It is an object to easily, and using existing devices, perform shadow enhancement that achieves an increase in the feeling of depth of 2D video. The input image data are first converted into brightness information by a brightness information calculation portion. Then, based on that brightness information, the normal direction and the edge information in the pixel targeted for processing are estimated by a normal direction estimation portion. A corrected gradation derivation portion then performs correction processing such as the addition of shadow component on the input image based on the brightness information and the estimated normal direction and edge information to create a processed image that has a feeling of depth, and then an output portion converts this to a predetermined image format and outputs it. In this way, it is possible to easily increase the feeling of depth of a 2D image through the addition of shadow, for example, in accordance with the characteristics of the input image.
