Project Description

EIA1956視頻分辨率測試標(biāo)版 EIA-1956 Resolution Video Test Chart

EIA VIDEO RESOLUTION PATTERN

EIA VIDEO RESOLUTION PATTERN 技術(shù)參數(shù)

1EIA-1956用于測試攝像機、數(shù)碼相機、拍照手機的錄像性能。

分辨率是衡量攝像機優(yōu)劣的一個重要參數(shù)，指的是當(dāng)攝像機攝取等間隔排列的黑白相間條紋時，在監(jiān)視器上人眼能夠看到的線數(shù)，當(dāng)超過這一線數(shù)時，屏幕上就只能看到灰蒙蒙的一片而不能再分辨出黑白相間的線條。清晰度又分為水平分辨率度和垂直分辨率。

測試方法，攝像機拍攝綜合測試圖，用目視法觀察監(jiān)視器上圖像中心楔上能分辨的線數(shù)或十組中心清晰度線段能分辨的線數(shù).

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
