Abstract

An RB rate calculator calculates an RB rate based on an R signal and a B signal. A starting point changing unit changes a starting point based on the RB rate. An offset calculating unit calculates an offset value to adjust for selection of a basic depth model type based on a bottom high frequency component evaluation value. An adding unit adds a signal from the starting point changing unit and an offset. Another adding unit adds an offset-added signal from the adding unit and a basic depth model-composed image signal supplied from a composing unit, and generates depth estimation data wherein a degree of superimposition of object information is changed according to a composition of a composed image of basic depth models selected to be composed.

Dependent claims

A depth estimation data generating apparatus comprising:

a generating unit which generates images of a plurality of basic depth models respectively indicating depth values of a plurality of basic scene structures;
a first calculating unit which calculates a composition ratio between the images of the plurality of basic depth models by using statistics of at least some pixel values in a predetermined region in a screen of a non-3D image, so as to estimate a scene structure of the non-3D image to which depth information is neither included explicitly nor included implicitly like a stereo image;
a composing unit which composes the images of the plurality of basic depth models generated by the generating unit according to the composition ratio and generates a basic depth model-composed image;
an object signal generating unit which generates an object signal indicating object information about concavity and convexity of a pseudo 3D image from the non-3D image;
a second calculating unit which calculates an offset value for emphasizing the object information about the concavity and convexity indicated by the object signal, by using the statistics of at least some of the pixel values in the predetermined region in the screen of the non-3D image;
a compensating unit which compensates for the object signal based on the offset value;
and
an adding unit which adds the object signal compensated for by the compensating unit to the basic depth model-composed image composed by the composing unit to generate depth estimation data for generating an image having a viewpoint different from the non-3D image, the image constituting a pseudo 3D image with the non-3D image.
