CMOS digital image sensor features global shutter
Semiconductor component company ON Semiconductor has introduced a high-performance CMOS global shutter image sensor for machine vision and mixed reality applications.

The AR0234CS 2.3 Mpixel CMOS digital image sensor is designed for a variety of applications including machine vision cameras, AR/VR/MR headsets, autonomous mobile robots (AMRs), and barcode readers. The device captures 1080p video and single frames operating up to 120 frames per second (fps).

The sensor, says the company, produces crisp and clear images by minimizing frame-to-frame distortion in high-speed scenes and reducing the motion artifacts other image sensors experience. The AR0234CS's pixel architecture delivers the high dynamic range needed to support lighting conditions from the darkness of night to bright sunlight.

The low noise and improved low-light response, says the company, makes the sensor suitable for applications spanning across consumer, commercial and industrial IoT, and the extended operating temperature range makes it deployable in challenging outdoor conditions.

"The need for quality image sensing is increasing, as more manufacturers are automating with vision-based expert systems," says Gianluca Colli, vice president and general manager, Industrial and Consumer Sensor Division (ICSD) Group at ON Semiconductor. "That demand requires optimizing size, performance and power of the image sensor. ON Semiconductor is one of the first manufacturers to recognize and respond to this need with the AR0234CS."

Other advanced features of the AR0234CS include: 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; and horizontal and vertical mirroring, windowing, and pixel binning. Together with the AP1302 Image Signal Processor (ISP), the AR0234CS offers a comprehensive camera system that can be designed and developed quickly for fast time-to-market.

In addition, says the company, system designers can access its 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 color and mono variants, with 0° or 28° CRA. Samples and development hardware are available now.
