Join us at the International Technical Exhibition (ITE) in Yokohama, Japan 4-6 December. We will introduce and demonstrate additions to its latest CMOS-based QUARTZ and SAPPHIRE camera series and CCD-based OPAL and TMX series including:
As part of the International Standards Meeting, a technical meeting of the committees GenICam, USB3 Vision, GigE Vision, Camera Link HS and CoaXPress. AIA, EMVA and JIIA together, in October 2013 in Schongau, Germany, there was a CoaXPress plugfest. For more overall details on the meeting, there is a nice article from Vision Systems Design: http://www.vision-systems.com/articles/2013/11/international-machine-vision-standards-meeting-sees-a-number-of-key-developments.html
Photonics has a leading role in many technical developments, including healthcare innovations. Adimec (Netherlands) and LL Tech (France), together with several partners, as part of the CAReIOCA project are developing & validating a high-resolution high-speed imaging-based medical device to perform non-invasive optical biopsy for cancer assessment.
In photographic terms, dynamic range indicates the ability of a camera to reproduce the brightest and darkest portions of an image. It is one of the key parameters for determining the right machine vision or industrial camera for your system [for more background information on using dynamic range to compare cameras, click here]. But there is more to dynamic range beyond the value provided on the specification sheet - there are different situations with varying requirements such as machine vision or viewing applications. Even in machine vision (controlled lighting situations), there can be different needs depending on the system environment. There is functionality that can be added to the camera for better performance in specific conditions. Here are more details…
Adimec adds the CMV12000 image sensor to the QUARTZ CMOS-based high-speed camera series, the new 12 Megapixel, 66 fps Q-12A65 machine vision camera.
The capability of a machine vision camera to capture the details of a scene is defined by several parameters with dynamic range at the top of the list. High contrast images require a high dynamic range. One problem is there can be different ways to calculate dynamic range, which makes it difficult to compare cameras and sensors on paper. Also, dynamic range and the signal to noise ratio (SNR) are sometimes considered interchangeable for CCD and CMOS image sensors and cameras providing further confusion.
What do you do when a great solution is just not the perfect fit? Adimec developed one of the best CLAs in the world. It is a compact and cost effective solution for fluoroscopy, surgery, universal RF, and Cardio-vascular applications. It provides excellent image quality while reducing the radiation doses patients are exposed to. Unfortunately it didn't fit to Apelem's system because it did not have the right interface. Together with Apelem we created a Camera Lens Assembly with the GigE Vision interface for their imaging systems used for digital radiology and bone densitometry. Here’s the story…
There is a lot of buzz about the improved camera that will be available in the iPhone 5S released this month. One of the surprising announcements from Apple was the increase in pixel size from 1.4um to 1.5um and the statement “bigger pixels = better picture.” This got us thinking about a topic we previously discussed in detail about why cameras for consumer electronic products are not used for machine vision or global security applications.
When zooming in and out, it is critical that the object remain in the same position in the real time video, especially in outdoor imaging and mission critical global security applications. For example, when observing one person in the crowd, you would want to be able to zoom in and out without losing track of the person. Full motion video cameras with integrated zoom optics ensure very accurate alignment of the sensor behind the lens to maintain the line of sight over the zoom range.
In theory, bigger pixels on full-HD CCD image sensors are better for global security applications because they are more sensitive for improved low light performance. The drawback is that bigger optics are required so size, weight, power, and cost (SWaP-C) requirements are challenged. As many systems are upgrading from standard definition to full-HD cameras or adding HD daylight cameras for full motion video, the question is how to find the optimal balance.
