ABSTRACT:
An image information transmission system according to the present invention is a system for transmitting image information. The system is arranged to receive a transmitted analog image signal and form digital image data by sampling the received analog image signal, then set a transmission-path characteristic by performing discrete Fourier transform operations on data which constitute a predetermined part of the formed digital image data, and then apply waveform equalization correction processing to the formed digital image data in accordance with the set transmission-path characteristic. Accordingly, the system is capable of transmitting image information accurately without being influenced by time base variations which occur on a transmission path.
