Patent ID: 8630480

Claim:
An image processing apparatus comprising: at least one image processor having a depth-information extraction section, a luminance extraction section, a contrast extraction section, a gain generation section, and a correlation estimation section, wherein said depth-information extraction section is configured to extract depth information of an image of an Mth frame of an input moving image, said luminance extraction section is configured to extract luminance components of said image of said Mth frame of said input moving image, said contrast extraction section is configured to extract contrast components of said image of said Mth frame of said input moving image on the basis of said luminance components of said image of said Mth frame, said gain generation section is configured to compute a gain map CG for adjusting contrast components of said image of said Mth frame on the basis of said contrast components of said image of said Mth frame and said depth information of said image of said Mth frame, said correlation estimation section is configured to compute values of correlations between images of at least two frames including an (N−1)th frame and an Nth frame (where N>0), and said gain generation section is configured to estimate a gain map EG for adjusting contrast components of said image of said Nth frame from said computed gain map CG for adjusting said contrast components of said image of said Mth frame and said computed correlation values.
