IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
First Claim
1. An image processing device comprising:
- a data input unit configured to receive an input image, depth data indicating depth of the input image, and a shooting parameter of the input image;
a parameter input unit configured to receive a transformation parameter as a parameter on projective transformation of a three-dimensional model;
a transformed image generating unit configured to generate a transformed image by performing projective transformation based on the transformation parameter in the three-dimensional model obtained from the input image, the depth data, and the shooting parameter;
a blank area detecting unit configured to detect a blank area in the transformed image, the blank area being a group of blank pixels that do not correspond to any pixel in the input image; and
an output unit configured to output the transformed image in the case where a blank value indicating size of the blank area is smaller than or equal to a threshold value.

Abstract
There are provided an data input unit configured to receive an input image, depth data, and a shooting parameter, a parameter input unit that receives a transformation parameter as a parameter on projective transformation of a three-dimensional model, a transformed image generating unit that generate a transformed image by performing projective transformation based on the transformation parameter in the three-dimensional model obtained from the input image, the depth data, and the shooting parameter, a blank area detecting unit that detects a blank area in the transformed image, the blank area being a group of blank pixels having no corresponding pixel in the input image, and an output unit configured to output the transformed image in the case where a blank value indicating size of the blank area is smaller than or equal to a threshold value.
