ルーメン-ルクス計算機 — ANSIルーメン & ルクス換算 | TheaterOwl

Calculating Lumen & Lux 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.

仕組み

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.

活用 사례

• When simulating the installation space before purchasing new Lumen & Lux equipment
• When wanting to optimize the performance of an existing home theater system and achieve professional-level tuning
• When needing to find a compromise for the best audiovisual experience within space constraints

ルーメン-ルクス計算機の使い方

ルーメン → ルクス と ルクス → ルーメン のモードを切り替えてください。光量値と面積を入力して変換します。

ルクスは1平方メートルあたりの照度を測定し、ルーメンは光源の総光束を測定します。1ルクス=1ルーメン/平方メートル。

ANSIルーメンはスクリーン上の9点で測定されます。ピークルーメンは中央のみで測定され、20〜50％高くなります。比較は常にANSIルーメンで行ってください。
