Head-mounted camera
First Claim
1. A head-mounted camera comprising:
- image pickup means including a photographing optical system in which a focal distance is changeable and an image pickup element for converting an optical subject image formed by the photographing optical system into an electric image signal;
display means for displaying a photographic frame indicating a photographic range as a virtual image so that the photographic frame is superimposed on a subject substantially directly observed by a photographer;
photographic-frame setting means for setting a visual angle of the photographic frame displayed by the display means as the virtual image and observed from the photographer; and
focal-distance setting means for setting the focal distance of the photographing optical system so that the visual angle of the photographic frame set by the photographic-frame setting means coincides with a field angle of the image pickup means.

Abstract
A head-mounted camera of the present invention includes the following elements. A first image pickup device includes a first photographing optical system that can change the focal distance and a CCD for converting a subject image formed by the first photographing optical system into an image signal. A see-through image display portion displays a photographic frame indicating the photographic range as a virtual image so that it is superimposed on a subject substantially directly observed by a photographer. A remote controller includes a second operation switch for setting the visual angle of the photographic frame when viewed from the photographer. A controller/recorder includes a first CPU for setting the focal distance of the first photographing optical system so that the visual angle of the photographic frame set by the second operation switch coincides with the field angle of the first image pickup device.
