本文叙述一个微机数字图象处理系统——IP-82,并详细介绍其 TV 图象输入装置 IID-2。IP-82系统,具有输入输出速度高,通用性强和应用灵活等特点。在系统设计中,对微型机图象内存进行了改造,解决了 TV 数字图象的高速输入输出问题。TV 图象可通过 IID-2以512×512的图象密度实时地输入到计算机图象显示内存,系统数据总线的数据传送率达10M Byte/sec,使系统具备了处理单幅活动 TV 图象的能力。IID-2还能作为一台通用外设与其他微机系统配接,有人工和程序控制输入的功能,输入图象尺寸规格较多,并有采样频率连续可调,图象开窗,拼接等功能,为用计算机进行图象信息处理提供了有力手段。
This article describes a computer digital image processing system - IP-82, and introduces its TV image input device IID-2 in detail. IP-82 system, with a high input and output speed, versatility and application of flexible features. In the system design, the image memory of the microcomputer has been transformed to solve the problem of high speed input and output of TV digital images. TV images can be input to the computer image display memory in real time via the IID-2 at an image density of 512 x 512. The data transfer rate of the system data bus is 10 M Bytes / sec., Allowing the system to handle single-event TV images Ability. IID-2 can also be used as a common peripheral with other computer systems, with manual and program control input function, the input image size specifications, and the sampling frequency continuously adjustable, the image window, stitching Function, for the use of computer image information processing provides a powerful tool.
