The shutter of the camera determines how and when light is recorded during each exposure. Today, Philips is going to introduce how Sony pregius series global shutter CMOS sensors provide clear and undistorted images.


BSI sensor inverts the traditional design of the front illuminated sensor, making it easier for photons to enter the photodiode of each pixel.

The fourth generation pregius s continues the traditional advantage of compact performance, and it is no exaggeration to say that it overturns the design rules of sensors. The pregius s uses a back illuminated (BSI) sensor to reduce pixel size, improve resolution, and simultaneously improve quantum efficiency and sensitivity.

Initial model

The initial models with the pregius s sensor are currently:

FLIR Blackfly ® S uses the most advanced ice shape sensor in the industry, which has powerful functions, so that you can easily generate the accurate image you need, and accelerate the development of your application. FLIR blackfly s usb3 with imx540 24.5 MP (15 FPS): monochrome, color and FLIR blackfly s GigE with imx542 16 MP (7.5 FPS) are global shutter sensors.

Blackfly S GigE

The FLIR Oryx 10gige camera family supports up to 10Gbit / s transmission speed and is able to capture 12 bit images with 4K resolution at a frame rate of more than 60fps, allowing system designers to take full advantage of the latest sensors. Furthermore, FLIR Oryx 10gige is a global shutter sensor with imx530 24.5 MP (35 FPS).

Pregius s provides high resolution with compact sensor size without affecting imaging performance, thus reducing system cost and improving throughput.

1. Higher resolution and lower complexity

As the first sensor in the pregius s series, the 24.5 MP imx530 / 540 can replace a variety of low resolution cameras to reduce your system complexity and cost.

2. Better imaging performance at lower price

New 2.74 for pregius s sensor µ M-pixel is nearly twice the pixel density of the old pregius sensor. Therefore, the footprint is reduced, which allows the use of compact and affordable optical components, so that a 24.5mp global shutter CMOS sensor can be concentrated in the space of ice block, and the price is quite competitive.


Pixel size differences between different generations of Sony pregius sensors

The new pixel design also significantly reduces the lens shadow of the compact C interface lens with a sensor size of up to 4 / 3 inch (about 1.9 cm). The back illuminated pixel design can receive the incident light with higher angle, which helps to improve the imaging quality of low-cost electronic components. Pregius s can use compact lens on large high resolution sensor without losing image quality.

Compared with imx530 / 540 pregius s sensor, the pixel density of imx253 pregius sensor is higher.

3. Increase system throughput

Global shutter reading can ensure fast moving target capture without distortion. Higher sensitivity can shorten the exposure time and increase the throughput, so that you can complete the analysis and inspection of goods in a shorter time, and improve the speed of the production line.

4. Reduce lighting costs

Sony pregius s sensor not only has the characteristics of fast global shutter reading and low reading noise of previous generations of pregius, but also combines the high quantum efficiency and pixel density of starvis.

The pregius s sensor can shorten the exposure time in weak light. For example, the imx530 / 540 can achieve excellent quantum efficiency up to 71.5%, which is higher than 65% of previous generations of global shutter sensors. As the new backlight pixel design will continue to retain the expected low reading noise and high image quality of the pregius sensor, the upgrade will not affect performance.

Although the front illuminated imx250 has larger pixels, the peak QE of BSI imx530 / 540 is higher.

The pregius s retains low read noise

By combining the global shutter reading and low reading noise of the pregius sensor with the high quantum efficiency and pixel density of starvis, Sony has established a new benchmark for CMOS imaging sensors.

Application advantages


Global shutter technology represents an important step in the production of high-quality images, even under challenging conditions, as sensing turns to a vision based system that enables interconnected devices to truly “see” and interpret their environment.
