PORTABLE DEVICE WITH CAMERA, AND IMAGE PICKUP METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To automatically perform photographing while covering a photography mistake, even if the photography mistake occurs because setting cannot be switched in accordance with photographing contents.

SOLUTION: A central AF evaluation value operating circuit 77 calculates a central AF evaluation value from the contrast of a center area of image data 80. A peripheral AF evaluation value operating circuit 78 calculates AF evaluation values of the divided areas other than the central area 80a, and selects a divided area having the highest AF evaluation value and being suitable as a focusing position. The AF evaluation value of a selected divided area 80b is used as a peripheral AF evaluation value. A system controller 70 compares the central AF evaluation value with the peripheral AF evaluation value. If the peripheral AF evaluation value is higher than the central AF evaluation value, focusing is performed on the basis of the central AF evaluation value to perform photographing, and after that, focusing is performed on the basis of the peripheral AF evaluation value to perform photographing.
