Patent number: 8780109Abstract: By adjusting parameters of single-eye 3D information on the basis of the visual-sense characteristic of a human being, it is possible to present a 3D image more hardly causing the human being to have a feeling of discomfort and a feeling of displeasure. An input-value-adjustment-quantity determination section determines an adjustment quantity of an input value on the basis of an evaluation function to serve as an adjustment quantity corresponding to a determined depth adjustment quantity. An adjustment-gain computation block computes a gain value of each of spatial-frequency components of an input 3D image on the basis of the adjustment quantity of the input value. An image adjustment block adjusts the spatial-frequency components in accordance with the gain values computed for the spatial-frequency components respectively. The present application can be applied to typically an image processing apparatus for adjusting depths of the input 3D image.Type: GrantFiled: May 17, 2012Date of Patent: July 15, 2014Assignee: Sony CorporationInventors: Yasuhide Hyodo, Shuichi Takahashi, Satoshi Shioiri
