JAI GO-X 5GigE models with 4th generation Sony Pregius S CMOS sensors

JAI has expanded on its GO-X Series by adding 12 5GigE models featuring the latest Sony Pregius S 4th Generation CMOS Backside Illuminated (BSI) sensors. These models have resolutions ranging from 5.1 megapixels to 24.5 megapixels and importantly are designed using readily available components to ensure a prompt delivery process.

JAI GO-X 5GigE camera models are small size, light weight, and require low power consumption. JAI's proven cleanroom assembly manufacturing process provides cameras with high reliability in the field. They are designed with internal membranes to prevent dust migration. Additionally, all the usual features in JAI cameras are provided, including region-of interest (ROI), image flipping, image mirroring, blemish compensation and shading correction. They also offer some new advanced features as described below.

Like the 24 GO-X GigE and CXP models released earlier this year, these 5GigE camera models feature 4th generation Sony Pregius S CMOS BSI sensors - perhaps the most advanced global shutter sensors available.

How does Pregius S Technology benefit industrial camera users?
Backside illumination for better sensitivity
Backside Illumination (BSI) is a sensor design that allows light to be captured via the back of the photodiodes – hence the term "Backside Illumination." This process of capturing light contrasts with traditional "frontside illuminated" sensor designs where wiring and circuitry are located on the layer above the photodiode and so partially blocking light.

The "S" in Pregius S stands for "stacked" and in the Pregius S design the wiring and circuitry layers are stacked below the photodiodes. A recent increase in sensors designed using BSI technology provides evidence that when photodiodes are closer to the microlenses a wider angle of incidence for capturing incoming light is created. Consequently, with the wider sensing angle and no wiring circuitry getting in the way, BSI pixels are more sensitive than traditional frontside illuminated pixels.

Global Shutter to eliminate motion distortion

Sony's BSI technology has previously only been available in sensors with rolling shutter. The Pregius S series combines BSI technology with global shutter to allow users to capture crisp, undistorted images in any application.

Small pixels provide high resolution in compact sensor formats

The 2.74 µm pixel size means that cameras which use the Pregius S sensor can incorporate higher resolutions into smaller sensor sizes – meaning more pixels per square-millimeter of silicon. This means the sensors carry a lower cost-per-megapixel, and this saving gets passed along in the lower camera cost. Smaller sensors means less glass in the lens and so reduces lens cost as well. Smaller pixels typically means lower sensitivity, however the BSI technology makes up for this so that the sensitivity of Pregius S sensors is equal to or even better than larger pixel sensors.

Range of aspect ratios to fit application requirements


Additional on-sensor circuitry for advanced functionality

Gradation compression: For scenes containing a few very bright areas, this function lets the camera capture a full 12-bits of shading variation but compresses the output into 8-bit images to increase frame rates and decrease file sizes. Users can define how much compression to apply and where on the 12-bit scale it should begin.

Floating diffusion binning: In addition to 1x2, 2x1, and 2x2 binning performed on the camera's FPGA, JAI's monochrome Pregius S cameras offer 2x2 binning performed directly on the sensor. This "FD2x2 Binning" mode utilizes a readout strategy that combines the readout of four pixels through a single floating diffusion node. This not only lowers the readout noise for higher dynamic range and image quality, it also produces significant increases in frame rate over the FPGA-based binning modes.

JAI GO-X 5GE feature compact size, low weight and competitive pricing for a wide range of machine vision applications in industries such as:
Traffic and Transportation
Automation & Automotive
Packaging & Logistics
Medical Devices
Food & Beverage

JAI GO-X 5GigE cameras are particularly suited to applications in rugged environments with high-temperature and high-vibration where space and weight are a premium. In addition, GO-X Series cameras can be utilized in various types of embedded applications. The eBUS SDK for JAI offered free with GO-X Series GigE Vision and USB3 Vision cameras, is also available in a Linux for ARM version and compatible with the NVIDIA Jetson line of embedded system processors and carrier board.
New Advanced Features
The new GO-X 5GigE cameras with Sony Gen.4 sensor offer several advanced capabilities not found in other cameras including:
Xscale - a flexible, sub-pixel scaling function to help match pixel sizes, optical formats, and resolutions when replacing older cameras. Binning allows the addition of whole-pixels, Xscale allows the addition of fractions of pixels and so offers much greater flexibility.
Xpress - available in the new monochrome GigE Vision models, this function provides lossless compression to reduce data size and increase frame rates over standard GigE Vision bandwidths.
Gradation Compression - For scenes containing a few very bright areas, this function lets users capture a full 12-bit of shading variations but compress the output into 8-bit images to decrease file sizes. Users can define how much compression to apply and where on the 12-bit scale it should begin.
Colour Space Conversion - The colour models offer a colour space conversion function when using the in-camera 5x5 RGB debayering option. This lets users select what colour gamut works best for their needs. Choices include RGB, Adobe RGB, HSI, CIE XYZ, and a colour matrix circuit that lets users program their own custom RGB format.
Colour Enhancement - The colour models also include a function that can be used to increase the intensity of selected primary/complementary colours (red, green, blue, cyan, magenta, yellow) up to 2X their captured intensity.
Note: GigE Vision models will have 5x5 debayering included as part of a free firmware update scheduled for December 2022. Colour space conversion and colour enhancement will be included in this update but will not include RGB to HSI colour conversion capability.
