Digital camera with a number of photographing systems
First Claim
1. A handheld single-housing portable digital camera comprising:
- a first photographing system and a second photographing system which are integrally provided in the digital camera and each of the systems respectively photograph same subject;
a changeover switch which selects one of said first and second photographing systems for photographing the subject;
a display control unit which displays an image formed by one photographing system determined by said changeover switch, and which performs a display control so as to display information other than the formed image along with the formed image; and
a display unit that comprises a main-region and a sub-region, wherein the display control unit displays the image formed by the photographing system selected by the changeover switch at the main-region, and displays the image formed by the other photographing system at the sub-region,wherein the first and second photographing systems respectively comprise a focal lens and a focus adjustment unit that performs auto focusing, and the display control unit further displays onto the formed image indications of a result of focus adjustment by the auto focusing and a focusing range,wherein said display control unit performs the display control so as to display image information which is the information other than said formed image, and which represents an image formed by the photographing system other than the photographing system determined by said changeover switch, andwherein the indications of the result of the focus adjustment by the auto focusing comprises an indication of whether or not the auto focusing is successful or not, and the indications of the result of the focusing range comprise an indication of a range of the subject on which the focus is directed as a result of the auto focusing.

Abstract
A digital camera comprises two photographing systems which are independent of and substantially identical to each other, and each of which includes a photographing optical system and an image pickup device. The photographing optical system is configured to include a photographing lens, a focusing lens and an aperture stop. The focusing lens of one of the photographing systems is driven stepwise from a first predetermined position at which it is to be located when a focusing position lies at an infinite distance, toward a second predetermined position at which it is to be located when the focusing position lies at the closest distance, while the focusing lens of the other photographing system is driven stepwise from the second predetermined position toward the first predetermined position every step width. The contrasts of images formed by the respective photographing systems are evaluated while the two focusing lenses are being moved, and a position corresponding to the maximum value of the contrasts is determined as the focusing position.
