Featuring its well-thought-out design
STMicroelectronics features their VD55G1, a unique ultracompact and low-power image sensor in the ST BrightSense portfolio. It has been developed to enable the next generation of smart and power-efficient systems. Leveraging the world’s first 2.16 µm global shutter pixel, the sensor highlights maximum compactness. It has a tiny 2.73 x 2.16 mm² footprint that fits into the most size-constrained devices such as AR/VR glasses or personal electronics.
With its well-thought-out design, the VD55G1 maintains low power consumption even when pushed at the highest frame rates, making it ideal for battery-powered devices. In addition to this low operating power, the sensor embeds an auto wake-up feature. This enables the sensor to operate in an ultralow power sleepy mode when no change or event is detected. As soon as an event is detected, the sensor automatically sends a trigger to its host processor to switch into full streaming mode to capture the corresponding event. Thanks to this clever feature, vision system makers can finally get rid of the power-hungry, ineffective 24/7 operation of systems such as security cameras, auto-ID, or in-line product inspection.
Besides auto wake-up, the VD55G1 embeds a complete toolbox of on-chip features for optimizing image quality, adjusting frame rate, or improving data efficiency. Autoexposure, noise reduction, and various image corrections help to get stunning images directly from the sensor. This sensor can perform background removal for more efficient face ID, or capture event frames in an event-like mode, enabling the output of event information in a synchronous manner.
Combining a small form factor, power efficiency, and a full range of clever features, the VD55G1 is the ideal vision extension for the next generation of smart embedded systems. Its single-lane MIPI CSI-2 output and I²C or I3C control interface makes it natively compatible with the broadest range of processing units. To facilitate further integration, the sensor is provided along with development kits, camera modules, and drivers.
