Omnivision launches newest generation of the World’s smallest shutter image sensor

Wed, Jul 10, 2024

Omnivision has announced the new OG0TC BSI global shutter (GS) image sensor for eye and face tracking in AR/VR/MR consumer headsets and glasses. For the first time ever, Omnivision is bringing its patented DCG high dynamic range (HDR) technology to the AR/VR/MR market in the 2.2-micron (µm) pixel OG0TC GS image sensor.

With a package size of just 1.64mm x 1.64mm, the OG0TC is an ultra-small and low-power image sensor for optimizing primarily inward-facing tracking cameras. This small form factor is key to industrial designs as multiple cameras are required for tracking all aspects of the face (eyes, brows, lips, etc.). The OG0TC is pin-to-pin compatible with Omnivision’s previous-generation BSI GS image sensor for easy upgrades.

“Ultra-low power consumption is critical for AR/VR battery-powered devices, and our OG0TC BSI GS image sensor reduces power by more than 40% over our previous-generation OG0TB sensor, which is already an extremely low-power device,” says Devang Patel, marketing director – IoT/Emerging, Omnivision. “Pin-to-pin compatibility makes the upgrade to the OG0TC easy for our customers, so they do not need to make any change to their design to save power and enjoy new features like DCG™ technology.”

Key features of the OG0TC image sensor include:
● The sensor is built on Omnivision’s PureCel Plus-S stacked-die technology.
● It features Omnivision’s patented DCG HDR technology and offers 400×400 resolution with a 2.2µm pixel in a 1/14.46-inch optical format.
● Nyxel technology enables the best quantum efficiency at the 940nm near-infrared (NIR) wavelength for sharp, accurate images of moving objects.
● It consumes less than 40% of the power at 30 frames per second (fps) compared with the previous-generation sensor.
● The sensor’s high modulation transfer function enables sharper images with greater contrast and more detail.
● It supports a flexible interface, including MIPI with multi-drop, CPHY, etc.

Patel adds, “We are excited to introduce our single-exposure DCG HDR technology for ghost-free image capture to the AR/VR market. It already has proven to be extremely successful in the security, mobile and automotive industries.”

With a TV8 rating, the DW-YL relays offer high performance and durability, capable of handling up to 320A inrush current. Additionally, their low profile of just 15.8mm makes them suitable for applications where space is at a premium. These relays are also UL/C-UL and VDE certified, ensuring compliance with international standards.

The DW-YL series is particularly suitable for a variety of applications in lighting, IoT devices, and power distribution units (PDUs). In lighting, these relays can be used in electrical ballasts, smart lighting systems, and LED drivers where high inrush currents are common. For IoT applications, DW-YL relays are ideal for smart plugs and smart switches, providing reliable performance in compact devices. In PDUs, these relays can be used in multi-outlet power strips to ensure safe and efficient power distribution.

ST BrightSense image sensor ecosystem for advanced camera performance

Thu, Jul 04, 2024

ST has introduced a set of plug-and-play hardware kits, evaluation camera modules and software that ease development with its ST BrightSense global-shutter image sensors. The ecosystem lets developers of mass-market industrial and consumer applications ensure superior camera performance by designing-in ST BrightSense image sensors. By sampling all pixels simultaneously, unlike a conventional rolling shutter, global-shutter sensors can capture images of fast-moving objects without distortion and significantly reduce power when coupled to a lighting system.

ST BrightSense CMOS global-shutter sensors implement advanced backside-illuminated pixel technology. Their high sensitivity enhances low-light performance and permits fast image capture, enhancing responses such as obstacle avoidance in mobile robots and face recognition in personal electronics. The sensors’ advanced 3D-stacked construction allows an extremely small die area, easing integration anywhere space is limited especially in the final optical module, while enriching the products with advanced on-chip image processing for auto-exposure, correction, and calibration. Their MIPI-CSI-2 interface makes them ideal for embedded vision and edge AI devices.

ST’s cutting-edge sensor technologies are now available in a wide variety of markets through the ST BrightSense portfolio, highlighting industrial-grade products and 10-year longevity commitment. Widespread access to these sensors now lets developers bring high-performance machine vision to applications that face strict size and power constraints and challenging operating conditions. These include factory automation, scanning, domestic and industrial robots, VR/AR equipment, traffic monitoring, and medical devices.

ST’s new mass-market offering includes evaluation camera modules that integrate image sensor, lens holder, lens, and plug-and-play flex connector to enable instant integration of the image sensors. The modules offer a selection of tiny form factors down to 5mm2, various lens options to suit different application requirements, and a plug-and-play connector that allows easy swapping. A series of hardware kits helps developers integrate the sensors with various desktop and embedded computing platforms. Complementary software tools are available for free download on ST’s website, such as a PC-based GUI and Linux drivers that assist integration with popular processing platforms including STM32MP2 microprocessors.
