Image Sensor Chaos – Sony Pregius vs ON-Semi Python – What is best for my camera application?

Which image sensor and camera is best for my application?

This is total Chaos with so many new sensors!

The image sensor market has rapidly changed in the past year, and has become very chaotic in determining the best image sensor and camera for an application.  

Sony and ON-Semiconductor have both launched a family of image sensors which provide global shutter using advanced CMOS designs resulting in high speed, crisp images.  

These CMOS sensors are now a viable alternative to CCD’s and older CMOS technology, providing higher performance and lower costs.  

BUT.. Which one is most suited for my application?  

Its best to start with understanding what is most important application.  Do we need speed?  Low noise?  Dynamic Range? or maybe a combination of attributes.  

1st Vision has helped make sense of the chaos in providing some considerations and comparisons between the Sony Pregius and ON-Semi Python Series sensors in the following chart.    

 


From the data, you can use these general guidelines

  • If you need the highest speed,  ON-Semi is your choice.   
  • If you need the highest dynamic range, Sony Pregius is your choice.
  • As a great general all around sensor, the Pregius IMX249 sells for ~ $500 in both GigE and USB3  This camera is 2.3MP @ 40fps and can be used in VGA, XGA SXGA modes by setting a ROI.   Read about various resolutions with setting a ROI

Most applications however are not that simple to just choose an image sensor based on speed or dynamic range. In many cases it requires a combination of many factors such as signal to noise, quantum efficiency and saturation capacity.    

1st Vision has more specific data we can discuss with you from various tests we have run and applications solved.

SVS-Vistek IP67 cameras with direct drive for LED illumination

SVS-VISTEK makes it easier and more cost efficient to integrate industrial cameras for machine vision into harsh environments.  The BlackLine Series ECO and ECO^2 cameras are equipped with water and dust proof housings (IP67 protection) and M12 connectivity for industrial wiring.  This series features direct drive and control of LED illumination from the camera eliminating external controllers. 


These are perfect for industrial automation, robotics and harsh environment applications.  All cameras are GigE Vision compliant and work with 3rd party vision software such as Cognex Vision Pro, National Instruments, Halcon &  MV Tech.  

Key Features for the Blackline Series

  • IP67 Protection
  • M12 Connectivity
  • Direct Drive and Control of LED Illumination with power cables available for CCS LED illumination.  
  • Advanced I/O functions and hardware supporting industrial automation
  • Advanced thermal management.  (-10 deg C to + 45 deg C)
  • Series includes resolutions from VGA to 5MP using Sony and ON-Semiconductor image sensors
  • GigE Vision compliant  – fully compatible with 3rd party vision software packages

All specifications for the Blackline Series can be found HERE. 

A key feature in the ECO Series is the ability to direct drive LED illumination in continuous and strobe modes.  This feature allows the camera to be used as a strobe controller saving costs.   

Direct Drive of LED illumination features include 

  • Built in ability to strobe up to 3 Amperes
  • Power of the LED light is provided through power of the camera
  • Setting of pulse width and duty cycle is controller via GigE standard Cat 5 cable
  • Up to 2 LED illuminators can be used simultaneously and independent from each other.  
  • Control commands are integrated into SDK

Industrial Automation support
Integration into industrial automation is supported with SVS’s powerful SVCam I/O functions and IOMUX switch matrix.  The IOMUX switch connects inputs and outputs with the various functions of SVCam I/O.  This allows a combination of inputs with Boolean arguments for more advanced deployments.  

Watch this short video showing 4 easy steps to for industrial field connectivity!

SVCam I/O supports various functions in conjunction with the IOMUX switch.  These include a Sequencer, Pulseloop, debouncer and Prescaler function.  A quick start guide to the I/O controls can be found HERE  

Full Specifications can be found HERE.

It’s a “No-Brainer” – Why not standardize on 1 camera for less than $500?

In working with many OEM customers of the years, historically several camera models were used to cover multiple system designs.  These were cases where there was an offering of lower and higher resolution systems, in turn needing VGA and 2MP cameras for example.

The introduction of the Sony Pregius sensors have changed the need for multiple cameras given excellent performance and pricing.  It has become a “no-brainer” to think about standardizing on one camera and emulate various resolutions for < $500



1st Vision has reviewed various resolutions achievable within given optical formats using the Sony Pregius IMX174 and IMX249 sensors.  

In cases where we wish to standardize with one camera, we can simply set a Region Of Interest (ROI) and emulate various resolutions (7 in this evaluation). 

We reviewed resolutions from VGA to 2.3MP and have put in perspective to the optical format required.  

The following are several configurations you can achieve: 


2.3MP is achieved using the full frame and 2MP by setting a 1600 x 1200 ROI.  This will require a 1″ optical format lens.  






In cases, where your application only requires 1.3MP (1280 x 1024) or 1.4MP (1400 x 1050), simply set a ROI accordingly and pair with your desired 2/3″ focal length lens.




Simply need 0.5MP (800 x 600) to VGA (640 x 480)? Set your ROI accordingly and you can use any 2/3″, 1/2″ or 1/3″ format lens.








Various resolutions against the required optical format are shown in graphical form to the right and summarized below for the Sony Pregius IMX174 and IMX249 sensors


Once you have your desired resolution, you can calculate your lens focal length using our online calculator.  Using 5.86um as a pixel size, enter the effective number of pixels into the calculator along with working distance (WD) and field of view (FOV).  This will calculate your focal length in which you can then select a lens

The Sony Pregius sensors are featured by several camera manufacturers and expanding rapidly.  With pricing @ < $500 for the IMX249… Its a “No Brainer” to think about standardization!  

Why the big hype on the Sony Pregius Sensors?  These new sensors are becoming the workhorse in imaging with incredible dynamic range, sensitivity and speed.  Learn more in our blog which provides technical details and comparison images.

Teledyne Dalsa Turbodrive – GigE, Faster than GigE!

What is TurboDrive?

 

TurboDrive from Teledyne Dalsa, is a technology which enables cameras to transmit information at a rate exceeding the constraints of Gige Ethernet.  TurboDrive is a patent pending innovation that uses advanced data encoding techniques that look at the redundancy in the data coming out of the sensor. It uses image entropy based encoding to model pixel information with no loss of information. This enables faster data transmission on the link as each pixel is comprised of fewer bits for encoding.

 

Machine Vision cameras have traditionally used absolute encoding over 8 to 16 bits to transmit image information. For instance, in 8-bit, each pixel takes a value ranging from 0

(black) to 255 (white). TurboDrive relies on localized relative encoding to examine each pixel in its context before encoding it. This generates a more compact encoding of the pixel information and enables TurboDrive to be more efficient by packing the same information in less bits. 

 

 

What are the benefits of TurboDrive?

 

  • Faster frame rates than GigE (125 MB/s) by up to 235%, BUT using standard GigE networks. 
  • Eliminate the need for faster interfaces (i.e Base Camera Link @ 255 MB/s), saving costs and complexity especially on long cable runs. 
  • Allows aggregate information from multiple camera onto a single link.  For example, data coming from 2 cameras could be sent on same network card.
  • More efficient method of data packaging without any loss.       
  • Its essentially free with TeledyneDalsa cameras supporting TurboDrive 

 

Data sheets for all Teledyne Dalsa cameras with TurboDrive can be found HERE.  

 

Why you should be considering this technology?

 

Watch this short video to explain the technology in detail and how to speed up your systems over standard GigE networks.  

 

Seeing is believing!

 

In addition, we have a video showing Turbodrive in action.  We used the 2.3MP Nano-1940 camera, operating over a PoE network @ 80 fps which is ~ 150% over the GigE bandwidth!
