Global Shutter Image Sensor

Capturing high-quality, undistorted images at high speeds with original Pregius and Pregius S technology

Overview

Pregius and Pregius S are Sony’s technological trademarks for a group of CMOS sensor global shutters and their peripheral technologies.

CMOS image sensors with Pregius and Pregius S technology are ideal for imaging inspections in machine vision and the smart industry that require the processing of a large volume of image data at high speed, as they make it possible to capture high-quality, undistorted images at high speeds.

These products also expand the scope of their applications from factory automation to other industrial imaging and sensing contexts, such as traffic monitoring and infrastructure inspection.

Features

Provides undistorted images of moving objects

Global shutters function enables the capturing of fast-moving objects without distortion. Texts are legible in images

Faster signal processing with lower noise

Our proprietary column A/D conversion circuit realizes both faster signal processing and lower noise. Enhancing the high-precision image inspection, it helps to improve on-site productivity in manufacturing

A wide variety of pixel sizes available

Enhanced efficiency through higher precision and shorter time is a prerequisite for realizing advanced automation, such as by replacing naked-eye visual inspection, in manufacturing and logistics. Machine vision cameras are a primary device that perform the task, and they require high-spec image sensors with improved resolution and frame rates. Launched in 2014, Pregius technology image sensors have been significantly improving productivity by offering both high speed and high precision in their performance.

Boosting the number of pixels in an image sensor to meet the demand for even higher resolution would increase the chip size, which was a problem as it would make the camera larger. Conversely, reducing the pixel size to maintain the camera size would compromise the sensitivity and signal saturation levels due to the restrained light collection area per pixel. This would inevitably lead to deterioration of image quality, and in turn to inferior recognition/detection performance.

As a solution to these issues, the PregiusS stacked CMOS image sensor with an innovative new structure was launched in 2019 and succeeded in simultaneously realizing both higher definition and a more compact size. This extensive lineup of products will contribute to rapid advances in the machine vision industry.

Realizing both higher definition and smaller size thanks to Pregius S technology

The back-illuminated pixel structure adopted in Pregius S global shutter technology has made both higher definition and smaller size a reality, on top of its non-distortion imaging functionality.This new structure has a superior light collection efficiency compared to the conventional front-illuminated structure and, while maintaining the levels of sensitivity and saturation capacity, achieved a reduction of the pixel size down to 2.74 µm square, about 63% of the conventional models.*1  In addition, rearranging the circuit area from the edges to the back of the sensor area has helped to achieve a 1.7-fold increase in resolution for the same optical size and reduce the package size to about 91% of the existing products.*1

As a result, it can achieve a high-definition small-sized machine vision camera compatible with up to approx. 24.45 M effective pixels in a C-mount 1.2-type sensor, allowing more flexibility in its applications to systems and production lines.

Fast readout of captured data

Data readout has significantly improved (2.4 times faster than previous products*1) in Pregius S by virtue of the highly-flexible wiring layout potential of the back-illuminated pixel structure, together with the adoption of SLVS-EC, a high-speed interface standard for adopting the embedded clock style. This potentially improves the takt time and throughput of the manufacturing systems or equipment.

As technologies such as USB 3.0 and 5 GigE become more prevalent, our standard 5 Gbps-compatible product range is enhanced by an extensive lineup of high-speed products for high-end cameras that use a high-speed band, improving the productivity significantly through reducing the time necessary for inspection, image recognition, identification, measurement, and other types of measurement and inspection.

High definition imaging over a wide area

C-mount lens compatible image sensors are a standard option for industrial machines, but larger unit multi-pixel sensor will enable high-definition imaging of wider areas.
For example, a comparison between the images taken with 1/1.1” 12.37 M pixels sensor and one with 127.68 M pixels sensor clearly shows the difference. This will enable to lower capture frequency, which contributes to improved efficiency. It also enhances recognition accuracy by the high resolution imaging.
