Abstract
An image acquirer acquires paired left and right viewpoint images. A disparity calculator calculates a disparity between the left and right viewpoint images. A display properties memory stores naked-eye stereoscopic display properties such as recommended disparity values and a cross-talk rate. A disparity analyser reads the naked-eye stereoscopic display properties from the display properties memory and uses these properties to perform a disparity adjustment on the left and right viewpoint images. A multi-viewpoint image generator uses the disparity as adjusted by the disparity analyser to generate a multi-viewpoint image by performing a shift on each pixel of the left and right viewpoint images.
