Newsletter 02/2013


It’s finally summer in the city. And as you know from the song lyrics, sometimes you just want to find a shadow in the city. That’s the same with digital cameras: as soon as they reach or cross specified temperature limits, image errors and unreliable operation are the results. That’s quite different with our mvBlueCOUGAR-X, mvBlueCOUGAR-XD, and mvBlueLYNX-X cameras, all of which feature temperature sensors on the mainboard and on the image sensor! You can define temperature limits and as soon as the limits are crossed you can pass a signal to a digital output. With it you can control a fan, for example, to start the cooling process.

Avoid summertime sadness with our products and enjoy the summer while reading the latest trends in our newsletter.

Aptina sensors with 10 and 11 megapixels for mvBlueFOX3 available

The CMOS sensors by Aptina are characterized in particular by their A-Pix™ technology, which enhances the quantum efficiency by the use of light guides and deep photo diodes. This minimizes crosstalk and leads to sharper images with vibrant colors even in low-light conditions. Following models are available:

  • mvBlueFOX3-1031

    • 1/3“

    • 3.1 megapixels color sensor (2052 x 1536 pixel)

    • 30 Hz at full resolution

  • mvBlueFOX3-1100

    • 1/2.35“

    • 10 megapixels color and gray scale sensor (3664 x 2748)

    • 8.7 Hz

All sensors feature a Global Reset Release trigger functionality with the possibility to control a flash function to minimize rolling shutter artefacts.

Integrated lighting system mvXLamp as a prototype available on request

For the mvBlueLYNX-X smart camera an integrated lighting system (mvXLamp) is available as a prototype on request. The lighting system consists of eight LED’s working as four pairs. The control of the four pairs is flexible. On the one hand you can switch on the LED pairs by a global signal (for example if the sensor is exposed and acquires an image). On the other hand you can define an acquisition matrix which uses two additional input signals (e.g. an external trigger at an digital input) which can be assigned to the LED pairs. The current for each LED pair can be limited to a value of up to 1.8 A. There is a use case about controlling the integrated lighting system in the technical manual of the mvBlueLYNX-X:

09/23/2013 – 09/26/2013 Automation 2013 in Mumbai

Together with our partners, MATRIX VISION will exhibit at the Automation 2013 fair in Mumbai, India. At the stand J12-J13 in Hall 1 we will demonstrated the latest developments and trends in the digital image processing. We are looking forward to seeing you.

BTW, how do we test our software?

Every night we create a current version of our software (“Nightly“) using the current sources. This includes

  • Our driver interface (mvIMPACT Acquire),

  • Our image processing library (mvIMPACT SDK) and

  • The firmware of the cameras.

Afterwards, the result will be installed and tested on our test system. This system includes more than 500 different single tests like the exposure time check. For example if you double the exposure time, you should see this in the image data. „Every day we get the latest and tested version of our software. If a nightly has an error, the development department is informed automatically so that they can fix it,” says Horst Mattfeldt, product manager. „This automatism speeds up the development cycles and at the same time it improves the quality of our software. On top of everything, the developer can focus on programming and does not have to take care of organizational things,“ continues Mattfeldt.
