网格测试卡简介

　　今天跟大家讲讲什么是网格测试卡图，网格测试卡是用于电脑设计操作调整和控制电视摄像机。而网格测试卡的结构是由17条水平线和23条垂直直线组成的18×24个白色背景的正方形。

　　网格测试卡正是由于这些正方形的圆圈是应许粗略的视觉评估扫描性和线条用于调整定位，更轻松的了解分辨率的评估。

　　网格线的宽度为图像宽度的0.13%。大圆形线的直径为图像高度的83 1/3%，5个小圆形线的直径为图像高度的25%。 2个分辨率楔形以0°和90°的角度布置在大圆中，对应于2-10MHz的信号频率。 (标记以8 MHz和800线结束)TE187网格

　　下面呢就跟大家简单的讲解下什么是摄像机吧

　　摄像机可以作为一种视频的输入的设备，也可以作为最社会独立的产品的广泛的监控，远程视频，医疗，安防灯领域，也可以作为配件的广泛的运用于手机，笔记本，电脑等各种通信的手段，更是随着互联网的领域发展，以及光学的技术逐步成熟稳定，随着生活的提高人们对产品的认识度逐渐上升也对产品的要求越来越高也慢慢的步入人们生活的各个源头领域.

　　摄像机主要有摄像头、主控芯片、感应芯片以及电源灯配件组成，对目前市场这些配件并没有一致的要求，正是这些不一致的配件导致了产品的品质良莠不齐，也就直接决定了摄像机的产品性能指标于用户的实际感受相差较大，如果说一个好的产品没有一个好的质量的话，这个产品就是一个很失败的，这就看出了一个好的产品对一个质量的重要性。

　　Introduction to Grid Test Cards

　　Today we talk about what is the grid test card chart, grid test card is used for computer design operation to adjust and control the TV camera. The grid test card structure is composed of 17 horizontal lines and 23 vertical lines of 18 × 24 white background of the square.

　　It is precisely because these squares of the circle are promised to be rough in the visual assessment of the scanning and lines used to adjust the positioning, making it easier to understand the resolution of the resolution.

　　The width of the grid line is 0.13% of the image width. The diameter of the large circular line is 83 1/3% of the image height, and the diameter of the five small circles is 25% of the image height. The two resolution wedges are arranged in a large circle at an angle of 0 ° and 90 °, corresponding to a signal frequency of 2-10 MHz. (Marked with 8 MHz and 800 lines) TE187 grid

　　The camera can be used as a video input device and can also be used as a wide range of monitoring, remote video, medical and security lights in the field of independent products, and can also be used as accessories for mobile phones, notebooks, computers and so on. Communication means, but also with the development of the field of the Internet, as well as optical technology gradually mature and stable, with the improvement of people's awareness of the product gradually increased the demand for products is also getting higher and more slowly into the people Life of the various source areas.

　　The camera mainly has the camera, the main control chip, the induction chip and the power light fixture composition, the current market these parts does not have the same request, it is these inconsistent parts leading to the product quality varies greatly, also directly determines the camera product performance Indicators in the user's actual feelings vary greatly, if a good product does not have a good quality, then this product is a very failure, which saw a good product on the importance of a quality.
