Abstract

An image processing device for receiving input image data in which multiple images displayed in mutually differing directions from a display are combined includes: a crosstalk correction processor for performing a crosstalk correction; and a response speed improvement correction processor for performing a response speed improvement correction. The crosstalk correction processor has an optical crosstalk correction processor for performing an optical crosstalk correction, and an electrical crosstalk correction processor for performing an electrical crosstalk correction. The optical crosstalk correction processor performs the correction based on the input image data and outputs optical crosstalk correction processed image data.
