IMAGE TRANSMISSION METHOD

摘要

PROBLEM TO BE SOLVED: To improve the image transmission efficiency by dividing an original image so as to have these divided images similar to each other, transmitting the divided images after encoding them and giving interpolation to the wrong group via the corresponding part of another similar divided image if an error is detected in a received image. SOLUTION: An image conversion part 10 rearranges an original image to be inputted into plural images of high correlation on every pixel line. Then an encoding part 2 compresses and encodes the converted image data by an H. 261 encoding system or an MPEG1 system and builds the encoded image data into a transmission packet in every encoding unit GOB(group of block) to sends them to a transmission line 4 with addition of an error detection code. When an error is detected at the receiving side via an error detection part 12, an error interpolation part 13 performs the interpolation of the error by copying a normally received corresponding part from a divided image other than that having a wrong part. Then an image inverse conversion part 11 reconfigurates the divided images and outputs them. Thus a transmission error is easily interpolated with high precision and the accuracy of the reconfigurated images can be improved.
