最適視聴距離計算機 — SMPTE & シネマ規格 | TheaterOwl

Calculating THX Distance 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 THX Distance 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

THX視聴距離計算機の使い方

画面の対角サイズをインチで入力してください。計算機はTHX (36°)、SMPTE (30°)、一般的なテレビ (22°) の各規格に基づいて最適な視聴距離を計算します。

THXは映画館のような没入体験のために最も近い距離を推奨します。SMPTEは専用ホームシアター向けです。22°規格はリビングでのカジュアルなテレビ視聴によく使われます。

プロジェクタースクリーンでは、物理的なフレームサイズではなく投影画像のサイズを入力してください。
