Image sensor minimises distortion in machine vision and mixed reality applications

A combination of a high dynamic range and pixel design means that the AR0234CS CMOS global shutter image sensor by ON Semiconductor delivers image clarity at 120 frames per second.
The 2.3 Mpixel CMOS image sensor, with global shutter technology is designed for a variety of applications including machine vision cameras, augmented reality (AR), virtual reality (VR) and mixed reality (MR) headsets, autonomous mobile robots (AMRs) and barcode readers.

The AR0234CS captures 1080p video and single frames, up to 120 frames per second. It is claimed to have industry-leading shutter efficiency, to produce crisp and clear images by minimising frame-to-frame distortion in high speed scenes and reducing the motion artefacts that other image sensors experience.

The pixel architecture delivers high dynamic range to support lighting conditions from the darkness of night to bright sunlight. The low noise and improved low light response makes it suitable for applications spanning across consumer, commercial and industrial IoT. The extended operating temperature range makes it deployable in challenging outdoor conditions.

As manufacturers automate production, using vision-based systems, the need for quality image sensing is increasing, explains Gianluca Colli, vice president and general manager, Industrial and Consumer Sensor Division (ICSD) Group at ON Semiconductor. As a result, they are demanding optimum size, performance and power in image sensors, he continued.

The sensor also has programmable regions of interest with on-chip histogram, auto exposure control and 5 x 5 statistics engine, fully integrated strobe illumination control, a flexible row and column skip mode, along with horizontal and vertical mirroring, windowing and pixel binning.

Together with the AP1302 image signal processor (ISP), the AR0234CS delivers a comprehensive camera system that can be designed and developed quickly for fast time-to-market, says ON Semiconductor. System designers can access the DevSuite software to evaluate features and capabilities, configure and tune the sensor, and provide a ready-made output that is usable for further image processing.

The AR0234CS is offered in colour and mono variants, with 0 or 28 degree chief ray angle (CRA).

Samples and development hardware are available now through local ON Semiconductor sales support representatives and authorised distributors.
