Abstract
The present technology relates to an image processing apparatus and method and a program that enable natural representation of light in an image in accordance with a viewpoint. The image processing apparatus calculates information indicating a change in a light source region between an input image and a viewpoint-converted image that is obtained by performing viewpoint conversion on the input image on the basis of a specified viewpoint, and causes a change in representation of light in the viewpoint-converted image on the basis of the calculated information indicating a change in the light source region. The present technology can be applied to an image display system that generates a pseudo stereoscopic image with motion parallax from one image.
Claims12
An image processing apparatus, comprising:
- a central processing unit (CPU) configured to:
- estimate a first light source region in an input image;
- generate input light source region information that indicates the estimated first light source region in the input image;
- generate viewpoint conversion light source region information that indicates a second light source region in a viewpoint-converted image;
- calculate, based on the input light source region information and the viewpoint conversion light source region information, information that indicates a change between the first light source region and the second light source region;
- and
- change representation of light in the viewpoint-converted image based on the information that indicates the change between the first light source region and the second light source region.
An image processing method, comprising:
- in an image processing apparatus:
- estimating a first light source region in an input image;
- generating input light source region information indicating the estimated first light source region in the input image;
- generating viewpoint conversion light source region information indicating a second light source region in a viewpoint-converted image;
- calculating, based on the input light source region information and the viewpoint conversion light source region information, information indicating a change between the first light source region and the second light source region;
- and
- changing representation of light in the viewpoint-converted image based on the information that indicates the change between the first light source region and the second light source region.
A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by a computer, cause the computer to execute operations, the operations comprising:
- estimate a first light source region in an input image;
- generate input light source region information that indicates the estimated first light source region in the input image;
- generate viewpoint conversion light source region information that indicates a second light source region in a viewpoint-converted image;
- calculate, based on the input light source region information and the viewpoint conversion light source region information, information that indicates a change between the first light source region and the second light source region;
- and
- change representation of light in the viewpoint-converted image based on the information that indicates the change between the first light source region and the second light source region.
