摘要
In an image data transmission system which is for transmitting an image data signal from a craft flying over an object zone to an earth station and which comprises a first (photoelectric) transducer (34a) for producing a first partial (electric) signal representative of a partial zone when the craft is at a first position and a second transducer (34b) for producing a second partial signal representative of the partial zone when the craft is, a first duration later, at a second position spaced apart from the first position by a first distance, a delay circuit (36-1) produces a delayed signal having a delay equal to the first duration relative to the first partial signal. A time difference detecting circuit (36-2) detects a time difference between the delayed signal and the second partial signal and produces a time difference signal. A transmission processing circuit (36-3) processes the delayed signal by the use of the time difference signal and produces a processed signal. A level difference detecting circuit (36-4) detects a level difference between the processed signal and the second partial signal and produces a level difference signal. A transmitting unit (37) transmits the delayed signal, the time difference signal, and the level difference signal collectively as the image data signal to the earth station. It is possible to reduce data quantity of the time difference signal and the level difference signal to at least one-tenth relative to that of the second partial signal. IMAGE
