IMAGE PICKUP APPARATUS HAVING AUTO FOCUSING FUNCTION USING FRACTAL DIMENSION AND AN AUTO FOCUSING METHOD

摘要

An image pickup apparatus having auto focusing function using fractal dimension and an auto focusing method of an image pickup apparatus are disclosed, the apparatus characterized by comprising: a pickup unit; a fractal controller generating a fractal dimention value indicating chrominance information change per pixel of a pickup image of the pickup unit to determine whether the auto focusing has been adjusted; and an auto focusing adjustor adjusting a focus of the pickup unit in response to an auto focus adjustment signal from the fractal controller.
