Abstract:
1. 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, wherein when a photographing environment is an indoor environment, the background distribution extraction unit is configured to extract luminance information of the preview image and the photographed image, and generate the background distribution based on a luminance changing degree between the preview image and the photographed image, and when the photographing environment is an outdoor environment, the background distribution extraction unit is configured to extract contrast information of a plurality of preview images, and generate the background distribution based on the contrast information of the plurality of preview images.
