Battle of the Image Sensors – Sony IMX174 Vs CMOSIS CMV2000

 

Sony Pregius imaging sensors with a newly advanced pixel design provide unsurpassed high dynamic range, quantum efficiency and excellent signal to noise (SNR) ratios.  With a Dynamic range of 73 dB and a quantum efficiency of 76% (@ 525nm), this sensor will become a major work horse in the industrial imaging market.  Comparing these data points however can be mind boggling and leave you asking, “What’s the end result?” 1st Vision put the CMOSIS CMV2000 and new Sony Pregius IMX174 into the ring to battle it out!   
 
The old phrase of “A picture is worth a thousand words” definitely stands true in comparing sensors and reviewing images.  In our battle, we compared the CMOSIS CMV2000 (2MP CMOS)  sensor to the new Sony Pregius IMX174 (2.3MP CMOS) sensor.  We reviewed several of the key sensor aspects and are as follows. 
Specifications

From the specification standpoint, the IMX174 provides better values across the board.  (Refer to the SonyPregius Sensor page for detailed information on the terms)

   Comparison Data:


Round 1:  Saturation Capacity & Dynamic Range

Saturation Capacity or “well depth” is analogous to a bucket of water, however in lieu of water, we have electrons.  Given a larger bucket, we can pour more water in the bucket without it overflowing.  The water overflowing is analogous to “saturation”.  In turn, a sensor that has a larger saturation capacity (bigger bucket) can hold more electrons (water) without saturating (overflowing).  This would relate to the sensors overall dynamic range in that it will not saturate quickly in a given image, allowing us to see darker and lighter areas. 

The example below shows images comparing the CMV2000 and IMX174.  These were captured with the same lens, camera manufacturer and set at the identical exposures.  

Looking at these images, which one is the better sensor?  We would want to quickly say, “The brighter one!”, however brighter does not always mean better!

On the left CMOSIS image, we see a noticeable difference as it is starting to saturate especially on the lower right corner.  The colors are reaching peak levels in which they are close to saturating (brighter image).  For this given light level, our small “buckets” are getting full!

On the right IMX174 image, we can see similar brightness levels in the upper left corners, but the bottom right part of the image is NOT saturating, as well as the markers are not reaching peak values.  In essence, we have a small bucket with the CMV2000 and will overflow much faster than the larger bucket with the IMX174.  Relating back to our values in the chart, saturation capacity and dynamic range are much greater on the IMX174 and can be visibly seen in the images!  Sony Pregius wins round 1.

(Knowing this.. the brighter image does not always mean its a better sensor! )


Round 2:  Quantum Efficiency (Sensitivity)
In comparing the Quantum Efficiency values, we see the IMX174 is 13% higher.  This relates to the conversion of photons to electrons and in turn providing a higher numeric value in our image.  The images below were taken in very low light with a 10uS exposure.  The IMX174 provides a brighter image due to this added efficiency.



Sony Pregius IMX174 wins round 2 with a Knock Out!

The Sony Pregius pixel architecture is being expanded into many resolutions and will implemented into many industrial cameras.

This camera provides Versatility, Performance and a nice price. What is the JAI’s GO 5000 series?

JAI’s GO 5000 delivers an exceptional blend of high versatility, excellent performance, small size and best of all at a price of < $1K.  


The GO provides the perfect starting point for a wide range of machine vision applications.


The GO-5000 packs a high performance 5-megapixel CMOS imager (Anafocus Lince5M) into a compact form factor that fits in your fingertips. Using a combination of ROI and binning capabilities, this tiny camera can become almost anything you want – from a super-fast VGA camera (at nearly 450 fps) to a super sensitive camera using binning to create 10-micron, or even-20-micron effective pixel sizes.

High image quality
The GO-5000’s imager features a combination of analog and digital gain controls to reduce the amount of quantized noise in low-light images compared to conventional CMOS imagers offering digital gain functions alone. On the color models, an on-chip 4-channel analog gain function is utilized to allow individual adjustment of R, G, and B information for better white balancing with reduced noise.

Even at megapixel resolutions, the GO Series doesn’t resort to a rolling shutter or small pixels with low signal-to-noise ratios. 5-micron square pixels, global shutter, analog gain control, a built-in lookup table, and other advanced features help ensure image quality beyond entry-level expectations. 

Choose of image size and frame rate using Multiple ROI & binning options
Featuring multiple binning options and single or multiple ROI’s the GO-5000 can be easily configured to meet a wide range of customer requirements for resolution, speed, and optical formats.

For example, by creating a centered 1920 x 1080 ROI, users can configure the GO-5000 to provide high-speed 1080p HD video that fits completely within the optical format of a 2/3” C-mount lens. This is in contrast to CMOS cameras with 5.5 micron pixels which generate 1080p image sizes that are slightly larger than the standard 2/3” optical circle, thus requiring more expensive 1” image optics to ensure that vignetting will not occur.
Note: frame rates shown above are for GO-5000-USB and GO-5000-PGE, respectively.
Monochrome models feature a range of binning options including 2×2 and 4×4 binning to allow users to effectively create 10-micron, or even 20-micron, square pixels to maximize sensitivity and signal-to-noise characteristics for specific applications, as well as increasing the overall frame rates.

Choice of interfaces
Choose one of the advanced digital interfaces that best fits your needs. Options include powered interfaces (PoE) where a single-cable solution is desired, as well as both frame-grabber-based (PMCL) and “grabberless” configurations using GigE and USB3.0


Small size and weight
GO Series cameras measure 29 x 29 x 41.5 mm (excluding lens mount) and weigh less than 50 grams, enabling them to fit into small spaces or into vehicles or other applications where weight is critical.

The GO-5000 is one of the smallest 5-megapixel cameras available and weighs only 46 grams (lens not included)

Canon EF mount integrated into AVT’s GT1930L camera

Canon EF mount fully integrated 

The GT1930L EF is the first Allied Vision camera to receive an integrated Canon EF mount, allowing lens focus and iris to be adjusted through camera controls in the Vimba SDK or 3rd party software. No additional cabling is required, with lens drive power taken from camera power (PoE or Hirose powered). In the past, this has typically been accomplished via a third party mount adding more complexity to the overall solution.  

Stay tuned as this is the first integrated Canon EF mount..  but not the last!  Additional camera models will soon follow.  

Performance

The GT1930L EF is equipped with a Sony IMX174 Pregius™ global shutter CMOS sensor with a resolution of 1936 x 1216 pixels (2.35 MPixel) and frame rate of 50.7 fps (55.7 fps in burst mode) over Gige Vision interfaces. 

Extreme Conditions

The GT1930L EF is a great solution in applications where the GT’s impressive housing temperature range of -30 to +70 °C is an advantage, Canon EF lens control is needed, or a tight sensor to mount planarity tolerance is required.  Applications include outdoor imaging, traffic, high end security, MIL/Aerospace, machine vision and industrial inspection. 


Key Features include

  • Canon EF Lens control
  • Rugged Design for extreme environments
  • Power Over Ethernet (PoE)
  • Camera temperature monitoring
  • Extended Temperature range
  • IEEE 1588 Precision Timing Protocol
  • ROI capabilities
