There is provided an image-taking method and apparatus capable of quickly taking an image in which a human face is in focus. When an instruction to take an image is input, multiple images are taken with different focus positions. A human face in each of the images is detected, an area enclosing a detected human face is set as a focus evaluation area, and a focus evaluation value is calculated. Once focus evaluation values for all the images taken have been calculated, the image with the highest focus evaluation value among the images is chosen and recorded. Thus, an image in which the human face is in focus can be readily taken without having to perform cumbersome operations such as an image choosing operation.

A method and a system for scaling a digital source image consisting of a grid of X by Y pixels into a target image of a different resolution comprises the steps of / tools for:mapping the source pixels onto the target pixels;scaling the source image in the X or Y direction to produce intermediate pixels that are scaled in one direction by determining contributions to each intermediate pixel using a digital filter and accumulating the contributions for each intermediate pixel, wherein each source pixel contributes to one or more intermediate pixels and each intermediate pixel receives contributions from one or more source pixels; and subsequentlyscaling the intermediate pixels in the other direction by determining the contributions to each target pixel using the filter and accumulating the contributions for each target pixel;wherein each intermediate pixel contributes to one or more target pixels and each target pixel receives contributions from one or more intermediate pixels.The method is preferably carried out on a PE array in an SIMD (Simple Instruction Multiple Data) device.
