Project Description
EIA1956视频分辨率测试标版 EIA-1956 Resolution Video Test Chart
EIA VIDEO RESOLUTION PATTERN
EIA VIDEO RESOLUTION PATTERN 技术参数
1EIA-1956用于测试摄像机、数码相机、拍照手机的录像性能。
分辨率是衡量摄像机优劣的一个重要参数，指的是当摄像机摄取等间隔排列的黑白相间条纹时，在监视器上人眼能够看到的线数，当超过这一线数时，屏幕上就只能看到灰蒙蒙的一片而不能再分辨出黑白相间的线条。清晰度又分为水平分辨率度和垂直分辨率。
测试方法，摄像机拍摄综合测试图，用目视法观察监视器上图像中心楔上能分辨的线数或十组中心清晰度线段能分辨的线数.
Data: Based on EIA 1956 chart. Includes linear and pie shapes from 200 to 1000 lines, 10
step density tables, measurement bars and edge definition points.
Notes: Measurements of Tele-cine cameras for streaking, ringing, aspect ratio; scan linearity
and other video and cine systems. Available in other custom sizes on request
