Abstract:
An apparatus for correcting global mismatch in gain between first and second views forming a stereoscopic image comprising:a) means for generating a first histogram of said first view and a second histogram of said second view, each said first and second histogram representing a frequency of occurrence of a characteristic component of said first and second views, respectively;b) means for comparing said first histogram of said first view with said second histogram of said second view and estimating mismatch in gain, a, between said first and second views; and,c) means for correcting the first and second views of said stereoscopic image by multiplying said mismatch in gain a and a second signal representing the second view and generating a gain corrected second signal of said stereoscopic image such that said gain corrected second signal and a first signal representing the first view form a stereoscopic image of improved quality.
