Visual technology plays a crucial role in many automation activities, and fields such as manufacturing, entertainment, transportation, and healthcare are increasingly emphasizing the development of visual systems.

The market's demand for fast and accurate imaging is becoming increasingly urgent, and with the accelerated development of analytical technology and artificial intelligence (AI), a new generation of advanced visual systems has emerged, with high-speed, full frame global shutter sensors being the core of these systems. The global shutter can capture the complete view of the subject in real time, which is very important.

A system based on global shutter can eliminate many common visual artifacts in the visual system, such as oscillation, tilt, and spatial aliasing, which helps to improve speed and accuracy, thereby enhancing operational efficiency. For applications such as barcode scanning, machine vision (MV), and autonomous mobile robots (AMR), global shutter imaging technology is rapidly becoming a popular choice.

Global Shutter: Advantages and Features

The global shutter image sensor can capture all pixels simultaneously. Unlike the rolling shutter image sensor used in progressive scanning scenes, the global shutter image sensor ensures the capture of distortion free images.

If there are fast-moving objects in the scene, the advantage of this synchronous operation will be particularly evident, for example, on a factory assembly line, products will quickly pass through the camera. By using a global shutter image sensor, each pixel can accurately record the scene at the same time, thereby generating clear and distortion free images. This helps to accurately capture barcodes on moving objects, which is crucial for applications such as barcode scanning, machine vision, AMR, and AR/VR control.

Bar code scanner

Barcodes are commonly used to efficiently encode data, allowing staff to quickly and reliably perform scanning tasks such as inventory and order processing. Barcode scanning failure "may be an experience that each of us has had, where we must rescan and the efficiency is very low. If excess light can be suppressed during scanning, the global shutter can eliminate most of the errors and inaccuracies in barcode reading. The performance of global shutter sensors can be quantitatively evaluated through the Global Shutter Efficiency (GSE) metric. The higher the GSE, the better the effect of suppressing excess light, thereby improving processing speed and avoiding manual intervention and/or rescanning work.

Autonomous Mobile Robots (AMR)

The global shutter image sensor adopts a stereoscopic configuration, which can realize visual based synchronous positioning and map construction (SLAM) applications, helping factories and warehouses plan paths and avoid collisions with obstacles. This sensor enables AMR to efficiently and safely navigate through various complex environments.

Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR)

Global shutter images are more convenient for synchronizing inputs from multiple sources and can typically increase frame rates. These features help shape better and more enjoyable VR, AR, and MR experiences.

Global Shutter Solution for Machine Vision

Onsemi has developed the Hyperlux SG global shutter sensor series, which includes three image sensors: ARX383, AR0145, and AR0235, all of which have the advantage of global shutter and can provide specific functions for many critical applications,

These sensors are expected to achieve vision based SLAM, helping factories and warehouses plan paths, avoid collisions with obstacles, and enable AMRs to efficiently and safely navigate through various environments.

Thanks to its higher GSE, the Hyperlux SG image sensor greatly improves the efficiency of scanning barcodes and applications such as AV/VR/MR. In addition, high GSE and high frame rate also help ensure excellent fidelity and image quality, meeting the key requirements of these applications. In addition, users can customize image quality through low-power options and subsampling modes to meet specific application requirements. These sensors can also synchronously capture images from multiple perspectives, thereby helping to create 3D models and depth maps.

AR0235 is the highest resolution in the Hyperlux SG series. This is a 1/2.8 inch, 2.3Mp CMOS digital image sensor with an effective pixel array of 1920 (H) x 1200 (V). Its characteristic is the use of a global shutter pixel design, which can accurately and quickly capture moving scenes, with speeds even reaching 120 frames per second. At the same time, it also has full resolution characteristics, which can present clear and low-noise images under low light, bright, and mixed lighting conditions.

The AR0235 sensor performs excellently in handling high angular velocities, greatly reducing motion artifacts. Its GSE has doubled compared to previous generations, and it can efficiently capture images of rapidly moving objects and record videos.
