    摘要: An image information signal transmitting system of this invention is a system which divides an image information signal for one picture constituted by a set of picture element data into blocks each constituted by a predetermined quantity of picture element data, transmits the picture element data on each of the blocks on the basis of a mode selected from among a plurality of transmission modes each of which allows a different quantity of picture element data to be transmitted and a mode information signal indicative of the transmission mode of each of the blocks, and restores the picture element data on each of the blocks to the original image information signal. The system is arranged to store the transmitted picture element data, read out the stored picture element data at a data readout rate of one kind which is selected from among a plurality of different data readout rates and which corresponds to the kind of transmission mode indicated by the transmitted mode information signal, and implement a data restoring processing on the picture element data thus read on the basis of a data restoring processing of one kind which is selected from among a plurality of different data restoring processings and which corresponds to the kind of transmission mode indicated by the transmitted mode information signal. With this arrangement, it is possible to realize reductions in the size, weight and cost of the apparatus without deteriorating an image information signal to be transmitted.
