視野角計算機 — 水平 & 垂直スクリーン角度 | TheaterOwl

Calculating Viewing Angle 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 Viewing Angle 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

視野角計算機の使い方

画面の対角サイズ、アスペクト比、視聴距離を入力して、水平・垂直の視野角を計算します。

THXは没入感のある映画体験には水平36°以上を推奨。20〜30°は映画鑑賞に快適です。15°未満ではディテールが失われます。

アスペクト比が広くなると、同じ対角サイズでも水平視野角は広がり、垂直視野角は狭まります。
