PURPOSE:To surely transfer data without being influenced by the disconnection of a transmission line by shotening a transfer time required for spatially transmitting data such as image information. CONSTITUTION:Image data are processed through a DCT part 11, a quantizing part 12 and a data area dividing part 13, converted into plural digital signals having respectively different carrier frequency bands and a spatially transmittable transmission format and outputted from infrared LEDs 16a, 16b, 16c as remote-controlled signals. These signals are received by photodiodes 17a to 17c, converted into current/voltage signals through current/voltage conversion parts 18a to 18c and extracted as signals in prescribed frequency bands, the extracted signals are synthesized by a data area synthesizing part 24 and the synthesized signal is decoded to the original image signal by prescribed image processing. |
