IMAGE ACQUISITION DEVICE AND METHOD FOR FOCUSING IMAGE ACQUISITION DEVICE

摘要

An image capturing apparatus is configured to store the control result of a focus position during scanning of segmented regions 40 and determine an initial focus position in scanning of the (n+1)th segmented region 40, based on the control result stored during scanning of the nth (n is an integer of 1 or more) or earlier segmented region. The foregoing technique allows this image capturing apparatus to roughly determine the initial focus position in the next-scanned segmented region 40 by making use of the control result of the segmented region 40 the scanning of which has been already completed. This can suppress increase in processing time necessary for imaging, by simplification of pre-focus.
