Title:
HIGH PRECISION ELECTRONIC CAMERA AND ITS CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/1996/027980
Kind Code:
A1
Abstract:
A device capable of changing the optical axis of an incident beam, such as a variable-apex prism (2), is disposed in an optical system of an electronic camera. When driven by an actuator (11), the variable-apex prism (2) changes the optical axis of the incident beam and guides light, which would be incident to opaque portions (21) between openings (20) of a CCD (3), into openings (20). The actuator (11) is controlled in such a manner that the direction of the optical axis sequentially changes, and the CCD (3) produces electrical signals from light incident to virtual openings (22) assumed to be in a plurality of positions on the opaque portions (21). An image memory stores a plurality of frames of image data outputted from the CCD (3). A signal processing circuit (8) combines these frames of image data and outputs one high-definition image having a greater number of pixels than that of the CCD (3) used.
