METHOD AND APPARATUS FOR ENCODING/TRANSMITTING IMAGE |
摘要 |
An image encoding/transmitting apparatus and method implemented by applying the vector quantization technology utilizing the differential pulse code modulation system in which an estimated error signal is compared with a threshold value to generate a change or movement detection signal and a differential signal, which are then quantized so as to be transmitted and received wherein the polarity of the differential signal is judged by a polarity judgment circuit, a polarity is assigned to the threshold value based on the judgment value by a polarity adding circuit, the differential signal is corrected depending on the threshold value with the polarity, and the corrected differential signal is quantized so as to be transmitted and received. |
