Image processing apparatus, image processing method and program

摘要

An apparatus and a method for performing a parallax control of a left image and a right image applied to display of a stereoscopic image are provided. The apparatus includes a left image transforming unit for generating a left image-transformed image by changing a phase of an image signal of a left image which is to be presented to a left eye in a right direction or a left direction and a right image transforming unit for generating a right image-transformed image by changing a phase of an image signal of a right image which is to be presented to a right eye in the left direction or the right direction. For example, each image transforming unit generates a differential signal by applying, to an input image, differential filter coefficients of coefficient series of opposite characteristics, and generates a parallax-controlled transformed signal using combining processing in which the differential signal or a non-linear signal of this differential signal is added to an original image signal. This processing achieves processing for, e.g., reduction or enlargement of a parallax range.
