2K2K square resolution CMOS image sensor maximises vertical coverage

For security wide-field of view and AR / VR / MR pass-through cameras, Omnivision’s first 2K2K (2048 x 2048) square resolution CMOS image sensor introduces features to the industry. The OS04E10 is claimed to be the industry’s first image sensor with digital watermarking, a built-in anti-spoofing feature that ensures no tampering with the original video source takes place. 

The 2.0 micron pixel image sensor is designed for 1:1 aspect ratio security systems to maximise vertical coverage in security wide-field of view (dome, fisheye, and doorbell) cameras as well as pass-through (AR / VR / MR) cameras. The sensor captures real-time fast-moving video and features always-on low power mode at 512p for pre-roll video recording capabilities.

Security has become the largest CMOS image sensor market segment after mobile and computing devices. From 2021 to 2027, according to Yole Intelligence’s Imaging for Security 2022 report, this market segment is expected to grow from $2.1 billion to $3.6 billion at a 9 per cent compound annual growth rate (CAGR).

“Pairing the OS04E10 with Omnivision’s OA7600 and OA8000 [ASICs] provides a total battery-powered camera system with always-on and pre-roll video recording capabilitie,” said Devang Patel, marketing director for the IoT and emerging segment at Omnivision.

The OS04E10 image sensor has a 2.0 micron pixel with a 1/3.11-inch optical format and is based on Omnivision’s PureCelPlus technology, which is claimed to reduce pixel crosstalk and noise for better colour reproduction under low-light conditions. Its onboard Nyxel near-infrared (NIR) technology ensures low to no ambient light image capture with IR source will result in clear and crisp images. It can also provide opportunities for camera designers to extend battery life. The sensor’s two-exposure staggered HDR mode increases dynamic range. The OS04E10 supports MIPI and LVDS interfaces. 

Samples of the OS04E10 are available now, and it will be in mass production in the second half of 2023.

ToF sensors advances use less energy or double range

Metasurface lens technology is introduced by STMicroelectronics in its second generation, FlightSense multi-zone direct time of flight (ToF) sensor. The VL53L8 uses less energy and can range twice as far as existing products, said the company. 

The FlightSense ToF ranging sensor for smartphone camera management and augmented reality / virtual reality  (AR / VR) offers up to four metres in range in all zones indoors, while reducing the power consumption by half compared to the previous-generation device, operating in common conditions. 

The ToF sensor’s metasurface lens technology and power-efficient architecture reduces battery loading, extends camera autofocus ranging and enhances scene-understanding features, explained Eric Aussedat, executive vice president and general manager of the imaging sub-group within ST’s Analog, MEMS and Sensors group.

What is claimed to be the world’s first optical metasurface technology was developed in partnership with Metalenz. It enables optical systems to collect more light, provide multiple functions in a single layer and deliver new forms of sensing in smartphones and other devices, in the form factor of a single, compact package, added ST.

This second-generation ranging sensor incorporates an efficient optically diffractive metasurface lens technology, manufactured at the company’s 300mm fab in Crolles, France. The VCSEL driver is three times more capable than the previous generation with an efficient VCSEL, enabling the VL53L8 to deliver twice the ranging performance of earlier VL53L5 or reduce power consumption by 50 per cent, when operating in comparable conditions. It delivers this performance while maintaining the same field of view and discrete output-ranging zones (4×4 at 60 frames per second or 8×8 at 15 frames per second).

The module embeds a high output 940nm VCSEL light source, an SoC sensor with an embedded VCSEL driver, the receiving array of SPADs (single photon avalanche diodes) and a low power, 32-bit microcontroller core. 

The VL53L8 adopts a metasurface lens technology in both the transmit and receive apertures and delivers 16 or 64 discrete ranging zones with stable and accurate ranging, said ST.

The sensor is housed in a single reflowable component that offers 1.2V and 1.8V I/O compatibility for ease of system integration. It is also claimed to significantly reduce the host processor loading over the demands of the first-generation sensor.

Like all other FlightSense ToF proximity sensors, the VL53L8 retains an IEC 60825-1 Class 1 certification and is fully eye-safe for consumer products with an advanced lens detach detection system. 

The VL53L8 can be used in smartphones and tablets in both user-facing, like object tracking and gesture recognition, and world-facing applications, such as laser-autofocus, camera selection, touch-to-focus, and flash dimming. It is also suitable for accessories in personal electronics equipment (e.g. smart speakers and AR / VR and mixed reality (MR). The VL53L8 will deliver even greater benefit to these features in low-light conditions, said ST. It can also support indoor/outdoor detection and smart-focus bracketing, as well as consumer lidar, where depth mapping is required. 

The VL53L8 is entering mass production now for select customers.

Sensor tracks motion and orientation for IoT and metaverse

Sensor fusion for motion tracking, heading and orientation detection is provided by the FSP201 low power sensor hub microcontroller released by Ceva. It is designed for use in consumer robotics and smart devices which use motion tracking and orientation such as 3D audio headsets or XR (extended reality, or augmented, virtual and mixed reality) glasses. They can also be used in six-axis motion use cases across the IoT and the metaverse.

The FSP201 is based on Ceva’s proprietary MotionEngine sensor processing software and a low-power 32bit Arm Cortex M23 microcontroller. Manufacturers can choose from a pre-qualified list of external six-axis IMU (inertial measurement units) sensors (i.e. accelerometer plus gyroscope). These are from different sensor suppliers, thereby ensuring supply chain flexibility. The sensor options can be used to provide correction smoothing actions and auto-centring for example. The former corrects orientation drift slowly and transparently allowing head and body tracking by the user for an immersive XR or 3D audio experience, the latter dynamically recentres the soundstage in 3D audio applications based on a user’s gaze to maintain immersion in dynamic conditions and eliminate drift. Other options are sensors with tilt independent heading, which allows for proper heading output even when a robot’s driving surface is uneven, enabling rapid adjustment to obstacles or changes in flooring types and ones with inclination detection to provide three degrees of freedom robot orientation to detect surface issues that could cause the robot to become stuck or damaged.

Proprietary algorithms are able to monitor changes in sensor performance and temperature during live operation for dynamic calibration. Several low-cost MEMS sensors from leading suppliers are pre-qualified and have drivers pre-integrated to accelerate development and ensure supply chain flexibility, added Ceva.

The FSP201 is designed to be versatile, using I2C and UART interfaces for chip connectivity and can be placed directly on the target product’s main circuit board or designed into a separate module. It is also code-compatible with the BNO08X series of nine-axis sensor system in package (SiP) products. 

The FSP201 and evaluation tools are available for immediate sampling via designated distributors.
