Abstract

PURPOSE:To simultaneously photograph videos in two directions by providing one or more reflecting mirrors on an optical path and making two videos passing through two optical paths formed into an image on one image pickup element. CONSTITUTION:The title device is constituted of the image pickup element P, the optical paths L1 and L2 and the reflecting mirrors m1-m4. Namely, two optical paths L1 and L2 are provided for one image pickup element P and one or more reflecting mirrors m1-m4 are provided on the optical paths L1 and L2. The videos which pass through the optical paths L1 and L2 are respectively reflected by the reflecting mirrors m1-m4 and conducted to the image pickup element P to be formed into the image there. When the two optical paths L1 and L2 are parallel, the device can be applied, for instance, for stereoscopic photographing. Thus, two different videos can be simultaneously photographed and the device can be applied for stereoscopic photographing, etc.
