Rolling-shutter CMOS image sensors set new low-power industry benchmark

The Hyperlux™ LP image sensors from onsemi can extend battery life by up to 40%, with three options for resolution, and an advanced pixel design for all lighting conditions.

onsemi has introduced the Hyperlux LP family of rolling-shutter image sensors, which offers lower power consumption than any other product in the class while producing crisp, vibrant images even in difficult lighting conditions.

The Hyperlux LP family is comprised of three image sensors:

AR0544 with 5 Mpixel resolution
AR0830 with 8.3 Mpixel resolution
AR2020 with 20 Mpixel resolution

All members of the Hyperlux LP family have the same pixel size and optical performance. Each product line is made up of multiple variants which give design engineers the flexibility to meet the needs of a wide range of application requirements. Options include mono, red/green/blue (RGB) and RGB + infrared variants in both packaged and bare die formats.

The sensors’ low-power performance is valuable because cameras for applications such as machine vision or surveillance are often placed in locations that can be difficult to reach for replacing or recharging a battery. Numerous features of the Hyperlux LP products support low system power consumption:

Wake-on-motion: enables the sensor to operate in a low-power mode which draws a fraction of the power needed in high-performance mode. Once the sensor detects movement, it moves to a higher-performance state before image capture begins
Smart ROI: detects more than one region of interest (ROI) to give a context view of the scene with reduced bandwidth, and a separate ROI in the original detail
Near-Infrared (NIR) performance: produces superior image quality due to the innovative silicon design and pixel architecture, with minimal supplemental lighting

In addition, the Hyperlux LP image sensors reduce the burden on a host image signal processor or system-on-chip by pre-processing the image data to produce an application-specific output.

Evaluation Board

Part Number: AR2020CSSC13SMTAH3-GEVB

The sensor board for the AR2020, a 20 Mpixel CMOS image sensor, produces excellent optical performance in both the visible and near infrared portions of the spectrum. The sensor consumes very little power, making it ideal for use in battery-powered products such as surveillance cameras or video doorbells.

The sensor board can be interfaced to the Demo3 evaluation board, or to an AP1302 evaluation board stacked on the Demo3 evaluation board: in this configuration, it supports a maximum image resolution of 13 Mpixels.

The kit uses the DevSuite software from onsemi for system configuration. The software provides a comprehensive set-up interface, and provides features for evaluating the sensor’s features and capabilities. The sensor board is supplied with a lens.
