Abstract
An apparatus and method for digital auto-focus are provided. The apparatus includes a local block generator generating a local block from an input image, a distance-estimation unit estimating distances of each image of the local block, a focal-distance-setting unit setting one of the estimated distances of the local block image as a focal distance of the input image, a reblurred-image generator generating a reblurred image from the local block image, a reconstructed image generator generating an in-focus image focused to the estimated distances from the local block image, a local-block-image-matching unit matching the reblurred image to the in-focus image with different weight values based on the set focal distance, and a final-image generator generating a final image by summing the matched local block images.
