Project Description

EIA1956視頻分辨率測(cè)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(cè)試攝像機(jī)、數(shù)碼相機(jī)、拍照手機(jī)的錄像性能。

分辨率是衡量攝像機(jī)優(yōu)劣的一個(gè)重要參數(shù)，指的是當(dāng)攝像機(jī)攝取等間隔排列的黑白相間條紋時(shí)，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(shí)，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(cè)試方法，攝像機(jī)拍攝綜合測(cè)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
