Abstract:
1. A pseudo 3D image creation apparatus comprising: a memory configured to store a plurality of basic depth models indicating depth values of a plurality of basic scene structures; a calculator configured to calculate statistical amounts of pixel values in predetermined areas in a non-3D image to generate first evaluation values, wherein the non-3D image has depth information supplied neither explicitly nor, unlike a stereo image, implicitly; a calculator configured to calculate a statistical amount of pixel values in a whole of the non-3D image to generate a second evaluation value; a combining device configured to combine said stored plurality of basic depth models into a combination result according to a combination ratio depending on the generated first evaluation values; a generator configured to generate depth estimation data from said combination result and the non-3D image; a shifter configured to compute a ratio between the generated second evaluation value and a prescribed value and shift a texture of the non-3D image in response to the computed ratio and the generated depth estimation data to generate a different-viewpoint picture signal; and an outputting device configured to output the generated different-viewpoint picture signal and a picture signal representative of the non-3D image as a pseudo 3D picture signal; wherein the shifter compares the computed ratio with a threshold value to generate a comparison result and sets a coefficient depending on the generated comparison result, and shifts the texture of the non-3D image in response to a product of the generated depth estimation data and the set coefficient; and wherein the shifter sets the coefficient greater than 1 when the computed ratio is less than the threshold value.
