Screen Gain Calculator — Brightness & Foot-Lamberts from Gain Ratio | TheaterOwl

Calculate screen brightness in foot-lamberts and nits from screen gain ratio and projector lumens.

Calculating Screen Gain is a fundamental and crucial step in home theater design. It is not just about measuring distance; it must be designed based on scientific evidence to maximize human visual perception limits and immersion. Incorrect settings can cause eye strain or fail to take advantage of resolution benefits. This tool complies with industry standards such as THX and SMPTE guides to provide the most precise data.

Nasıl Çalışır

This system utilizes complex trigonometry and optical formulas. Based on the input variables (screen size, resolution, viewing angle, etc.), it simultaneously calculates the minimum distance where pixels do not appear clustered and the maximum immersion distance that fills the entire field of view. All results are reflected in real-time, suggesting figures optimized for the user's environment.

Kullanım Senaryoları

Perde Kazancı Hesaplayıcı Nasıl Kullanılır

Foot-lambert cinsinden parlaklığı hesaplamak için perde boyutunuzu, kazanç oranını ve projeksiyonun ANSI lümen değerini girin.

THX 12–22 foot-lambert önerir. ISF SDR hedefi 16 fL'dir. Standart mat beyaz = kazanç 1,0, gri 0,8–1,0, yüksek kazanç 1,3–2,5.

Daha yüksek kazanç parlaklığı artırır ancak izleme konisini daraltır. Ev sinemaları için 1,0–1,3 kazanç önerilir.
