ABSTRACT:
An image transmission apparatus of this invention generates an image signal for one field at a first rate, forms a first transmission image signal on the basis of the generated image signal, outputs the formed first transmission image signal for one field at a second rate lower than the first rate, forms a second transmission image signal having a smaller information volume than that of the first transmission image signal on the basis of the generated image signal, outputs the formed second transmission image signal for one field at a rate higher than the second rate, and selectively outputs one of the output first and second transmission image signals onto a transmission path, thereby providing, by a simple arrangement, an image transmission apparatus, which can selectively transmit an image signal onto a transmission path at one of different arbitrary rates in correspondence with an application purpose or display mode independently of the transmission rate of the transmission path, can display an image represented by an image signal transmitted from a transmitting apparatus in real time, and can assure low cost, low consumption power, and good operability.
