电视摄象图象输入设备是数字图象处理中的常规设备之一。其与其它图象输入设备相比,有着快速、灵活的独特优点。本文比较详细地叙述了电视摄象图象输入设备的设计思想,说明了采样频率的计算、采样方式的选择、采样点数的确定以及各主要部件的工作原理,并给出了该设备输入计算机数字图象的数学模型和信息的存储量。另外,本文还介绍了窗口技术和灰度面积计算等软件的硬化方法。
Television camera image input devices are one of the conventional devices in digital image processing. Compared with other image input devices, it has the unique advantages of fastness and flexibility. This paper narrates the design idea of television camera image input device in more detail, explains the calculation of sampling frequency, the choice of sampling method, the determination of sampling points and the working principle of each main component, and gives the input of computer digital The mathematical model of images and the amount of information stored. In addition, this article also introduced the window technology and gray area calculation software hardening method.
