PURPOSE:To send a color picture at high speed with a narrow occupied band width by converting an analog signal from a 1st storage device into a digital signal, storing sequentially the digital signal to a 2nd storage device and displaying a signal read from the 2nd storage device onto a lighting color display device. CONSTITUTION:A digital storage signal is read sequentially from a storage device at every 4-bit storage element, converted into an analog signal by a D-A converter 3, then reflected to air from a transmission antenna 5 by a transmitter 4. A signal caught by a reception antenna 6 is amplified and detected by an amplifier 7, converted into, e.g., a 4-bit digital signal by an A-D converter 8 and stored sequentially in the storage element of a memory device 9, in, e.g., the direction of depth. A signal is read sequentially periodically from the memory device 9 and sent to a display device 10. Thus, the color picture is sent with a narrow occupied frequency band width at fast speed. |
