CMOS global shutter image sensor meets all light conditions

The AR0144 global shutter, CMOS digital image sensor achieves fast, clean and accurate imaging in static applications such as high-speed barcode scanners, and dynamic uses including drones and augmented reality/virtual reality (AR/VR).

The 0.25-inch, 1.0Mpixel (1280H x 800V) sensor captures clean, accurate images with no artifacts in both bright and low light conditions, says ON Semiconductor. Its high shutter efficiency and signal-to-noise ratio minimise ghosting and noise effects, improving overall image quality.

The 3.0-micron pixel AR0144 incorporates an innovative global shutter design that is optimised to address the increasingly stringent demands for accurate and fast capture in static and moving scene applications. Available in monochrome and colour, the sensor is compact with a choice of either 5.6 x 5.6mm chip scale or bare die formats, to ease integration into space-constrained designs. 

Its features and capabilities enable the AR0144 to address the increasing number of diverse end applications for image sensors.  

In static applications such as bar code scanners, the AR0144 is easy to incorporate in the handheld product format and ensures first-time scanning saving power, time and inconvenience, claims ON Semiconductor. In dynamic applications such as drones, the sensor’s low power characteristics extend the time between charging, and its imaging performance supports better mapping of the environment for robust collision avoidance. Finally, in 3D camera and augmented reality / virtual reality designs, the AR0144 can provide a cost-effective and small form factor solution for capturing dual images for 3D mapping or depth sensing.

The AR0144 has a choice of master/video, trigger/single frame and auto trigger operating modes. Exposure time is controlled via a two-wire serial interface and configuration of both the window size and blanking times allows the resolution and frame rate (up to 60-frames per second at full resolution) to be adjusted to cover a particular region of interest. A range of customisation possibilities, such as tuning, windowing, adjustable auto-exposure control and auto black level correction can be drawn on to accurately match the specific needs of applications.

The AR0144 is available now in 5.6 x 5.6mm 69-ball CSP packaging and also as a bare die. The AR0144 monochrome device is in production now, with the colour version available later this year.
