OMNIVISION OS04A10 Expands Resolution To 4 Megapixels In Image Sensor User Guide

OMNIVISION OS04A10 Expands Resolution To 4 Megapixels In Image Sensor

Product Information

The OS04A10 is a 4-megapixel image sensor designed for various applications, including security cameras. It incorporates advanced technologies such as QE (Quantum Efficiency) and DCGTM (Dual Conversion Gain) to deliver superior performance.

The OS04A10 features excellent QE, allowing for lower power IR illumination in total darkness. This reduces system-level power consumption by an estimated 3x. It supports 940 nm NIR lighting, which is undetectable by human eyes in dark indoor settings, and 850 nm light, which is ideal for outdoor security cameras.

This image sensor achieves industry-leading SNR1850nm and SNR1940nm performance, surpassing competitors’ sensors by 2x to 3x. The integrated DCGTM technology provides outstanding Ultra-Low Light (ULL) and high dynamic range (HDR) performance. It also offers greater flexibility in selecting a companion image signal processor.

4-megapixel product brief

4-Megapixel Nyxel® NIR and Ultra Low Light Image Sensor

• OMNIVISION’s OS04A10 is a 2.9 µm pixel size, 4-megapixel (MP) resolution member of its industry-leading Nyxel® near-infrared (NIR) and ultra-low light (ULL) image sensor family. It provides security cameras with greater zoom range and AI-enabled surveillance systems with better object identification and facial authentication accuracy. Additionally, it maintains the industry’s best performance, day and night, for detecting incident light in both the visible and NIR wavelengths to produce even more precise color and monochrome images. The OS04A10 also features OMNIVISION’s PureCel®Plus-S die stacking technology, which enables its extremely small package and large 2.9 micron pixel size.
• OMNIVISION’s Nyxel® NIR technology imparts the OS04A10 with exceptional quantum efficiency (QE) of 60% at 850 nm and 40% at 940 nm, which is 3x to 5x better than sensors without this technology. This excellent QE enables the use of lower power IR illumination in total darkness, resulting in an estimated 3x reduction in system-level power consumption. Additionally, 940 nm NIR lighting cannot be detected by human eyes in dark indoor settings, while the 850 nm light is ideal for outdoor security cameras.
• The OS04A10 achieves industry leading SNR1850nm and SNR1940nm performance that is 2x to 3x smaller when compared with the leading known available competitor sensors. Additionally, OMNIVISION’s integrated DCG™ (dual conversion gain) technology provides the industry’s best ULL and high dynamic range (HDR) performance, along with greater flexibility in selecting a companion image signal processor.
