Methods and apparatus for rendering an image with depth-of-field display |
摘要 |
A depth of field rendering apparatus, method and program displays a sense of distance using a Z buffer to establish a depth direction of objects in an image and generating an image in a just-in-focus state while writing a Z value of each of dots in the image into the Z-buffer. A blurred image is produced from the just-in-focus image and portions of the blurred image are selectively overwritten on the just-in-focus image by comparing a preset Z value to the Z value of each of the data in the Z buffer.
