A double eye image pickup apparatus performs image pickup using a plurality of image pickup systems with partly overlapping fields in order to obtain an image at an arbitrary aspect ratio while correcting the registration and taking an image of occlusion area into consideration, and the apparatus has a device for setting a virtual projection plane in a subject space, based on image signals of overlap portions output from the respective image pickup systems, and a device for projecting image signals onto the projection plane to combine the image signals into a single image signal.
