Claims (2)

[Claims] 1. A first lens for shooting a subject at a first angle of view, and a second lens for shooting the subject at a second angle of view different from the first angle of view. An image pickup device comprising: an image pickup unit that simultaneously forms each light incident from the first and second lenses on one image pickup surface and converts each formed image into an electric signal. 2. A lens having a predetermined focal length, a separating means for separating the light incident from the lens into a first light and a second light, and a reflecting means for reflecting the second light. A second light reflected by the first light and the reflecting means
And an image pickup means for converting each of the formed images into an electric signal.
