適応型ローカルトーンマッピングによるハイダイナミックレンジの強化

Machine Vision is transforming industrial automation by enabling intelligent visual inspection, measurement, and decision-making across diverse sectors. As industries embrace digital transformation, machine vision systems are becoming essential for enhancing productivity, quality, and operational efficiency. These systems combine high-performance image sensors, advanced optics, and AI-powered processing to capture and analyze visual data in real time. From identifying defects in manufacturing lines to guiding robotic arms in assembly, machine vision ensures precision and consistency.

Driven by innovations in CMOS sensor technology, global shutter architectures, and AI-based image processing, machine vision systems now offer superior low-light performance, high dynamic range, and ultra-fast frame rates. onsemi’s portfolio, including the XGS, PYTHON, and Hyperlux sensor families, delivers scalable, power-efficient solutions tailored for both high-resolution and high-speed applications.

The integration of extended vision technologies like LiDAR, iToF and SWIR further expands machine vision’s capabilities, enabling accurate 3D mapping and object detection in dynamic environments. These advancements are pivotal for smart factories, autonomous robotics, and next-generation quality control systems.

オンセミは、2.1 µmスーパーエクスポージャ技術を採用した新たなピクセルイメージセンサファミリ「Hyperlux」を開発しました。Hyperluxは、センシングカメラとビューイングカメラの両方に対応する独自の機能を備えています。Hyperluxセンサは、3メガピクセル（MP）、8MP以上、120dBの単一露光フリッカフリーレンジで、比類のない150dBのハイダイナミックレンジ（HDR）画像をキャプチャすることができます。Hyperluxファミリは、高温（ジャンクション温度最大+100℃）でも、すべての信号対雑音比（SNR）の推移を30dB以上に保ちます。低照度環境では、極端な温度条件下で同じサイズのピクセルを持つ同等のセンサより優れた性能を発揮します。このオンセミ独自のセンサファミリは、最小のフォームファクタで最低消費電力を実現し、効率的なカメラ設計を可能にします。

Modern video surveillance demands high dynamic range, low-light sensitivity, and real-time processing to support intelligent monitoring in complex environments. onsemi’s CMOS image sensors, including the Hyperlux LP and Hyperlux LH series, are engineered to meet these requirements at low power consumption. These advanced sensors deliver low noise, high quantum efficiency, and high frame rates critical for capturing fast-moving subjects and maintaining image integrity in challenging lighting conditions. Hyperlux LP is optimized for low-power, compact devices, while Hyperlux LH targets high dynamic range (HDR) applications such as city-wide surveillance and traffic analytics.

Our best-in-class image sensor development ecosystem software reduces design time and accelerates time to market (TTM). The scalability and integration flexibility of our image sensors make them ideal for IP cameras, network video recorders (NVRs), and embedded vision systems. As surveillance systems evolve toward edge intelligence and 24/7 situational awareness, Hyperlux sensors provide the imaging foundation for next-generation security infrastructure.
