Title:
IMAGE SENSING APPARATUS
Document Type and Number:
WIPO Patent Application WO2005032124
Kind Code:
A3
Abstract:
A half- mirror (23) is interposed between a photographing lens (2) and a photographing CCD (21), and a focusing CCD (22) is movably inserted in the light splitting path of the half- mirror (23). In photographing, particularly in photographing of a motion image, the focusing CCD (22) is moved to search for an in- focus position. A position to which the photographing lens (2) is to be moved is decided from the positions of the focusing CCD (22) and photo-graphing lens (2) after search. The photographing lens (2) is directly moved to the decided position. The lens need not be moved for searching for an in- focus position during photographing, and in- focus image data can be recorded.
