oT-Record: Dynamic Brightness and High-Resolution Video Recording and Analysis System

last updated：Oct 23, 2026

Official site

A system capable of dynamically recording, viewing, and analyzing luminance distribution at high resolution and high frequency (such as luminance histograms and visualization of saturation).

oT-Record is a system that allows for the dynamic recording, viewing, and analysis of luminance distribution at high resolution and high frequency (such as luminance histograms and saturation visualization). By inputting data recorded with this system into HALDIS, it is possible to dynamically display the captured scene indoors with the same brightness as outdoors. ■ Dynamic luminance measurement of scenes or objects ■ Acquisition of a series of high-frequency, high-resolution images ■ Luminance analysis of recorded images 【Other Features】 ■ The included oT-Record software allows for viewing and analysis of the acquired luminance distribution data ■ Video playback is also possible ■ Changes in luminance are easy to visually confirm

Okutech Co., Ltd. is a Japanese company that develops, sells, and engineers innovative solutions for accurately "measuring," "reproducing," "displaying," and "verifying" outdoor dynamic environmental brightness (luminance) and color, including "HALDiS" (real luminance simulator), "oT-Record" (real luminance recorder), and "oT-Sim" (real luminance simulation). We provide a verification environment that reproduces outdoor dynamic environmental luminance indoors at a 1:1 absolute value, contributing to the reduction of man-hours in prototype manufacturing and outdoor testing (especially at night). Additionally, based on over 20 years of practical experience in high-standard road design for the Ministry of Land, Infrastructure, Transport and Tourism, we also possess and offer unique road generation know-how that excels in cost-effectiveness. In the field of fundamental research in optics, we have established a technical agreement with the French National Institute (ENTPE, Lyon).
