Image sensors save on power and costs

Ganesh Narayanaswamy, product line manager for image sensors at onsemi says the family enables up to 40% power savings, making them more efficient and lowers cost of ownership.

He points to numerous pain points in designing image systems which can mean the system does not meet customer expecatations.

“A low power footprint is essential,” he asserts.

Delivering excellent image quality and low power consumption the sensors maximize performance to capture crisp, vibrant images even in difficult lighting conditions.

The product family also features a stacked architecture design that minimizes its footprint and at its smallest approaches the size of a grain of rice, making it ideal for devices where size is critical.

Depending on the use case, customers can choose between the 5-megapixel AR0544, the 8-megapixel AR0830 or the 20-megapixel AR2020.

Home and business owners continue to choose cameras to protect themselves more than any other security measure, with the market expected to triple by the end of the decade. As a result, consumers are demanding devices that offer better image quality, reliability and longer battery life to improve the overall user experience.

With the image sensors, cameras can deliver clearer images and more accurate object detection even in harsh weather and lighting conditions. Additionally, these cameras are often placed in locations that can be difficult to access to replace or recharge batteries, making low power consumption a critical feature.

The Hyperlux LP family is packed with features and proprietary technologies that optimize performance and resolution including:

• Wake on Motion –Enables the sensors to operate in a low-power mode that draws a fraction of the power needed in the full-performance mode. Once the sensor detects movement, it moves to a higher performance state in less time than it takes to snap a photo.
• Smart ROI – Delivers more than one region of interest (ROI) to give a context view of the scene at reduced bandwidth and a separate ROI in original detail.
• Near-Infrared (NIR) Performance – Delivers superior image quality due to the innovative silicon design and pixel architecture, with minimal supplemental lighting.
• Low Power – Reduces thermal noise which negatively impacts image quality and eliminates the need for heat sinks, reducing the overall cost of the vision system.

“By leveraging our superior analogue design and pixel architecture, our sensors elevate the two most important elements people consider when buying a device, picture quality and battery life. Our new image sensor family delivers performance that matters with a significantly increased battery life and exquisite, highly detailed images,” said Ross Jatou, senior vice president and general manager, Intelligent Sensing Group, onsemi.

In addition to smart home devices, one of the other applications the Hyperlux LP family can improve is the office meeting experience with more intuitive, seamless videoconferencing solutions.

“Our video collaboration solutions require high-quality image sensors that bring together multiple factors for the best user experience. The superior optical performance, innovative features and extremely low power consumption of the Hyperlux LP image sensors enable us to deliver a completely immersive virtual meeting experience in highly intelligent and optimized videoconferencing systems,” said Ashish Thanawala, Sr. Director of Systems Engineering, Owl Labs.

The Hyperlux LP Image Sensor Family will be available in the fourth quarter of 2023.
