Abstract
An apparatuses and methods for correcting parallax information between pixels obtained by stereo image processing to more reliable values, wherein first a first parallax is calculated by establishing correspondence between pixels of a standard picture and pixels of a reference picture by an area base matching method using a predetermined evaluation function, a detected corresponding point is evaluated to be correct when the value of the evaluation function indicates a high correlation and then the calculated first parallax is used as it is, while when the value of the evaluation function shows a low correlation, the detected corresponding point is evaluated to be unreliable, the pixel exhibiting the highest correlation is found based on the value of the evaluation function between pixels contained in a predetermined pixel block having the pixel having the unreliable correspondence as a center pixel and the corresponding points, then the first parallax is replaced with the parallax of the found pixel for the correction.
