How to measure the dark noise profile in a camera

Posted by Benny Koene on Mon, May 22, 2017

In one of our previous blogs we already discussed how to use ImageJ to visualize image statistics and make dark noise visible. However before analyzing the dark noise with a program like ImageJ, it is important to measure the dark noise correctly. Here are some tips on correctly measuring the dark noise.

Why should cameras not have fans for accurate measurements?

Posted by Benny Koene on Thu, May 4, 2017

Cameras produce a significant amount of heat, especially the latest large resolution image sensors running at high frame rates such as the On Semi Vita25k, the Python 25k and the CMV50000. This heat is mainly originating from the image sensor (image read-out) and the FPGA (image processing) and it needs to be removed from the camera efficiently. Too much heat can damage the image sensor or FPGA. Furthermore the image noise will increase with increasing temperature.

Reducing system complexity with CoaXPress

Posted by Benny Koene on Thu, Mar 23, 2017

Often a robust and simple system design is more cost effective and also easier to maintain. Simple system design is achieved by using proven technologies and at the same time reducing the variety of technologies that are being used. Less cables and less hardware make a system even simpler, robust and cost efficient.

One of the strong advantages of CoaXPress (CXP) is that it is designed to simplify the system architecture.

What are the differences between the various Sony IMX Pregius image sensors?

Posted by Benny Koene on Thu, Feb 23, 2017

We have noticed there is some confusion about the various Sony Pregius image sensors and their resolution. The resolution doesn’t necessarily increase with a higher number in the sensor’s name. Therefore we will give in this blog a brief overview of the resolution of the Sony IMX250, IMX252, IMX253 and the IMX255 sensors. We also address the question which of these IMX sensor should I choose?

High full well capacity versus high dynamic range

Posted by Benny Koene on Fri, Feb 10, 2017

Very often high full well capacity and high dynamic range is mentioned in one sentence. However actually they are not per definition the same. For example at Adimec we do sell cameras with high full well capacity however if you are looking for a high dynamic range this might not be the camera of your choice. So what is the difference and when do you choose one over the other.

Practical tips for using software to analyze image quality

Next to writing blog’s I am also part of the support team within Adimec. To support customers the support team frequently has to analyze image quality. Image averages, standard deviations, or histograms are frequently used image properties that help us in our analysis but also cross sections of images come in handy.

Stable, predictable and reproducible latency with CoaXPress

Posted by Benny Koene on Thu, Jan 12, 2017

In a lot of machine vision applications it is important to know the exact time at which a camera records its image. For example if a strobe light is used, the camera should record when the strobe is on and not when the strobe is off! This is done via accurate triggering of the camera.

Another situation where latency or accurate triggering is important is if multiple cameras are being used. To be able to relate images with each other and to construct for example 3D images from a set of 2D images, such as with 3D All Optical Inspection (3D-AOI), it is necessary that the images are recorded at exactly the same time. This is especially true if the object of interest is moving along your inspection machine.

How to improve image quality under low light circumstances

Posted by Benny Koene on Wed, Dec 21, 2016

As today is the shortest day of the year (at least in the northern hemisphere) and the largest part of the day is dark, we though it a good moment to give you a few ideas on how to optimize image quality in low light conditions. Due to the simple fact that you need light to obtain an image with a visible camera, low light conditions are by definition challenging. However, even with low light you can take measures to obtain the best possible image result.
