In an image pickup system for use in combination with a craft (50) flying over an object zone (51), a plurality of photoelectric transducers are arranged in the craft to pick up partial images of the object zone, respectively, and are divided into forward and backward halves that are operable in cooperation with a signal processing unit (65) to obtain a stereo image of the object zone from the partial images. A selected one of the partial images is picked up from a selected one of the forward half transducers at a time instant and is thereafter picked up again at another time instant with an interval left between the time instants from another one of the backward half transducers that is symmetrical with the selected forward half transducer and spaced apart a predetermined number of photoelectric transducers from the selected forward half transducer. The interval is defined by the predetermined number. The signal processing unit may be located either in the craft or in a ground station.

In an image pickup system for a craft flying in a predetermined direction over an object zone, wherein the image pickup system comprises an optical system located in the craft for producing an optical image of said object zone on a focussing area of the optical system and image processing means coupled to the optical system for electrically processing the optical image, the image processing means comprising: a predetermined number including at least five photoelectric transducers associated with said focussing area to convert said optical image into partial electrical signals representative of partial zones of said object zone when said craft flies over each of said object zones, said partial zones being in one-to-one correspondence to said photoelectric transducers; signal processing means coupled to said photoelectric transducers for processing said partial electric signals into a plurality of stereo images; and means for enabling designating at least two base height ratios for obtaining said stereo signals.
