<P>PROBLEM TO BE SOLVED: To provide an image pickup device realizing the shortening of a release time lag and also the prolongation of the life of a battery because of the reduction of current consumption by preventing focusing action from being performed again when a focusing state is maintained after performing the focusing action once. <P>SOLUTION: Before performing the focusing action in response to focusing instruction operation, a CPU 11a compares present image data obtained immediately after the focusing instruction operation and obtained when a focus lens 1 exists at the previous focusing position detected by the previous focusing action with the previous image data obtained in the midst of the previous focusing action or immediately after finishing the previous focusing action and obtained when the lens 1 exists at the previous focusing position, and judges whether or not the focusing state from the previous focusing action is maintained. In the case of detecting the focusing position when the focusing state is not maintained, the lens 1 is not driven or the driving area of the lens 1 is narrowed. <P>COPYRIGHT: (C)2003,JPO |
