Patent ID: 8749653

Claim:
An apparatus for blurring a background of an image in a digital image processing device, the apparatus comprising: a digital signal processor for: generating a first generated image generated by a difference in brightness between: a first image created after a first input signal is received via a shutter-release button and before a second input signal is received via the shutter-release button; and a second image created with the flash being on after the second input signal is received via the shutter-release button; creating a third image when the flash is turned off after the second input signal is received via the shutter-release button; generating a second generated image by generating a difference in brightness between the third image and the first generated image; generating an inverted second generated image by inverting a brightness of the second generated image; separating a subject and background of the inverted second generated image; blurring the separated background of the inverted second generated image; and combining the third image with the blurred separated background into a final generated image.
