Problems solved by technology

[0005] However, if the increased parallax is greater than a certain level, the image perceived by the left eye will not be fused with the image perceived by the right eye, double images will appear, and stereoscopic viewing will not be possible (fusion limit)
Double images due to excessive parallax are known to cause eye fatigue

Abstract

Disclosed is an image processor which generates a three-dimensional image that is easy for an observer to view stereoscopically and thus does not tend to cause the observer to become fatigued, while easily adjusting the three-dimensional effect of any part of the three-dimensional image. A disparity correction unit (101) corrects disparity in a received disparity image to a given range, and outputs to a disparity conversion unit (103) the disparity image in which the corrected disparity has been stored. The disparity conversion unit (103) converts the disparity in the disparity image so that the disparity corresponding to the image of a main object determined by a main-object determination unit (102) has a given value, and outputs the disparity image obtained after the conversion to an image generation unit (104). The image generation unit (104) generates an image for the left eye and an image for the right eye based on the received disparity image and a received captured image, and outputs the images to a display apparatus. Consequently, the disparity is converted to enhance the three-dimensional effect of the main object.

Description

technical field [0001] The present invention relates to an image processor for generating three-dimensional images, an image display device including the image processor, and an image capturing device including the image processor. Background technique [0002] There is proposed an apparatus that simultaneously captures images of the same subject (hereinafter simply referred to as the same subject) using left-eye and right-eye cameras arranged side by side, by analyzing two image data (hereinafter simply referred to as the same subject) generated by the two cameras. image) to generate a three-dimensional image (also referred to as a stereoscopic image) by performing various image processing (see Patent Document 1). [0003] The gap between images generated by overlapping two images is called parallax. This parallax varies according to the distance from the camera to the object. [0004] For example, assume that two cameras are placed on a straight line, wherein the optical...
