In an image pickup system which is used on a craft flying over an object zone and comprises a first (photoelectric) transducer (21) for producing a first partial (electric) signal representative of a partial image of a partial zone lying forwardly of the craft flying at a first position and a second transducer (22) for producing a second partial signal representative of another partial image of the partial zone lying directly under the craft flying, an interval of time later, at a second position spaced from the first position by a distance between two partial zones picked up by the first and the second transducers when the craft is at the first position, a compression unit (90 ) compresses the first and the second partial signals into first and second compressed signals. A delay circuit ( 54-1) gives the first compressed signal a delay equal to the interval of time and produces a delayed signal. A subtracter (55-1) calculates a difference between the delayed signal and the second compressed signal and produces a difference signal. The first compressed signal and the difference signal are transmitted by a transmitter to a ground station to obtain a stereo image of the object zone. Preferably, the image pickup system should comprise a third transducer (23), another delay circuit (54-2), and another subtracter (55-2). The delay circuit is implemented by a memory.
