Abstract

PURPOSE: To make an efficient picture transmission possible by causing the information density detection unit of a transmission unit to receive low-information density signals and perform the skip operation to transmit frame information of scanning line information and causing a receiving unit to discriminate the outside-frame area.
CONSTITUTION: Scanning part 1 scans a picture having a frame, and converted scanning line information is stored in memories 20 and 21. In this case, information density detection unit 4 detects the level of the information density on a basis of information other than frame information, and stored scanning line information is transmitted from a transmission unit by the output of unit 4. That is, unit 4 of the transmission unit receives low-information density signals and performs the skip operation to transmit frame information of scanning line information, and a receiving unit discriminates the outside-frame area and reproduces the picture. As a result, picture transmission can be performed efficiently.
