Project Description
EIA1956視頻分辨率測試標版 EIA-1956 Resolution Video Test Chart
EIA VIDEO RESOLUTION PATTERN
EIA VIDEO RESOLUTION PATTERN 技術(shù)參數
1EIA-1956用于測試攝像機、數碼相機、拍照手機的錄像性能。
分辨率是衡量攝像機優(yōu)劣的一個(gè)重要參數，指的是當攝像機攝取等間隔排列的黑白相間條紋時(shí)，在監視器上人眼能夠看到的線(xiàn)數，當超過(guò)這一線(xiàn)數時(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(xiàn)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(guān)察監視器上圖像中心楔上能分辨的線(xiàn)數或十組中心清晰度線(xiàn)段能分辨的線(xiàn)數.
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
