Title: Method for encoding
Inventor: MATSUYAMA HISASHI
IPC: H04N19/146
Filed: 1987-12-18
Abstract: PURPOSE:To eliminate the uselessness to send the same information repeatedly and to practice an efficient encoding by comparing the concentration of present and previous frame and assigning a corresponding compression code respectively to a concentration difference when the concentration difference is less than a threshold value and to a concentration value when the concentration difference is more than the threshold value. CONSTITUTION:First, a concentration difference + or -1 is set as a threshold value. A CPU 5 attaches a synchronous code SYN at the top of a line, and compares the concentration of the picture element of the first transverse line of a present frame and the same position picture element of one frame before that. Then, when the concentration difference is within + or -1, a fixed compression code, which corresponds to a temperature difference as a graphic indicates, is attached. Besides, when the concentration difference is more than + or -1, a flag 001 to indicate that the following 4 bits are PCM codes and the PCM code (4 bits) of the concentration value are assigned, and the encoding of the next picture element is practiced in the same way. When the sending of one line is ended, the next one line is read out from a buffer RAM 16, and encoded in the same way as above. Thus, the data of one frame portion are compress-encoded and sent. Besides, the decoding of the encoding data is practiced in the converse procedure to those aforementioned.
