GMS低分辨率云图在1024×1024高分辨率显示器上的实时伪彩色显示

REAL TIME DISPLAY OF THE GMS LOW RESOLUTION PICTURE ON 1024×1024 MONITOR

摘要:

将GMS低分辨率卫星云图接收机输出的模拟信号,通过市话线,传送到远距离的使用单位,并在IBM PC/AT或PC/XT机上配置的1024×1024高分辨率图形显示器上作实时伪彩色分层显示。显示在屏幕上的图象可以放大1-16整数的平方倍,还可以上下左右移动,而不必修改显示存贮器的内容。可以在屏幕上同时显示四幅经缩小为512×512象素的云图,以分析天气演变过程。

Abstract:

Transferring the analog signal of the GMS low resolution cloudpicture by means of telephone wires from the receiver output to theremote user and real time pseudo color stratified display of the cloud picture on 1024×1024 high resolution graphic display connected to IBMPC/AT or PC/XT have been developed. The image displayed on thescreen can be zoomed by a factor of square of 1-16 in integer and panned without having to change any vedio RAM content. Four pictures reduced to 512×512 pixel can be displayed on the screen simulta-neously.
