  • Method, system, and computer program product for simulating camera depth-of-field effects in a digital image
    Patent number: 6590574
    Abstract: Camera depth-of-field effects are simulated through a system and method that blurs at least a portion of an image. A source image having a plurality of pixels is transferred to a frame buffer. Either during the transfer or after the transfer, a blending factor is determined for each pixel of the source image. A blurred copy of the source image is generated using hardware, software, or a combination of hardware and software. The blurred copy of the source image is then blended with the source image using the determined blending factors to produce an image having simulated camera depth-of-field effects.
