1. A pseudo 3D image generation device comprising: basic depth model generation units that generate a plurality of basic depth models having basic scenes used for estimating depth data based on a non-3D image signal and generating a pseudo 3D image signal; a combination unit that combines the plurality of basic depth models for generating a composite depth model based on a first control signal indicating composite percentages for combining the plurality of basic depth models; a depth estimation data generation unit that generates the depth estimation data from the non-3D image signal and the composite depth models; and a texture shift unit that shifts a texture of a non-3D image based on the depth estimation data for generating the pseudo 3D image signal.
