Abstract
Provided are an apparatus and method for generating an image with a defocused background. According to various aspects, a preview image is used as the basis for extracting a background distribution and a defocused background is generated based on the extracted background distribution. Accordingly, it is not necessary to photograph two or more images to generate a defocused background effect.
Claims20
An apparatus for generating an image with a defocused background, the apparatus comprising:
- a background distribution extraction unit configured to extract a background distribution based on a preview image corresponding to a photographed image;
- a defocused image generation unit configured to generate a defocused image for the photographed image;
- and
- an image combination unit for combining the defocused image with the photographed image based on the background distribution to generate the image with the defocused background.
A method for generating an image with a defocused background, the method comprising:
- extracting a background distribution based on a preview image corresponding to a photographed image;
- generating a defocused image for the photographed image;
- and
- combining the defocused image with the photographed image based on the background distribution to generate the image with the defocused background.
An image processing device comprising:
- an extractor configured to extract a background distribution of a photograph based on a preview image of the photograph;
- a defocuser configured to perform a blurring operation on the photograph to generate a defocused image;
- and
- a combiner configured to combine the photograph and the defocused image based on the background distribution to generate a photograph with a defocused background.
