图象数字化 meaning in Chinese

image digitizing, image digitization
map digitizing

In order to get real time images with high quality , it is necessary to transmit as many data as possible through the limited channel and compress the images as well . what ’ s more , it will increase the hardware system running speed , decrease the delay of transmission of the video signal so as to ensure the system functions at real time
然而视频图象数字化也给传输带来了数据量大的问题,要用有限的信道传输尽可能多的数据以实现实时显示,就必须将图象数据进行压缩,另外,数据量的减少,也有利于加快硬件的处理速度、图象的传输速度和减少传输时延,保证传输图象的实时性。
