Title:
STEREOSCOPIC IMAGE PICKUP DEVICE
Document Type and Number:
Japanese Patent JPH06327036
Kind Code:
A
Abstract:

PURPOSE: To pick up a stereoscopic image by a simple constitution without reducing a light quantity.

CONSTITUTION: An intersected point P of third and fourth mirrors 3 and 4 is arranged so as to be positioned in a screen including the incident eye of an image pickup lens, which is vertical to an optical axis. Then, right and left optical information is allowed to pass through the right half and left half of an image pickup lens 5, and each right and left information is image-formed in the same area on a CCD 6 regardless of the distance of a subject S. Therefore, at the time of opening and closing the right and left areas of a liquid crystal shutter 7 in a field cycle, only information for a left eye is image-formed in the odd-numbered field, and only the information for a right eye is image- formed in the even-numbered filed in a CCD 6. Thus, stereoscopic video signals can be obtained in the successive fields.
