The EMVA offers a series of four free 30 min webinars on the EMVA1288 standard to characterize cameras in an objective way. The 2021 produced webinars provide the necessary knowledge to select the best possible camera for a given application using the EMVA 1288 summary data sheet and all the knowledge required to be certified as an EMVA 1288 user.
The speaker is Prof. Dr. Bernd Jähne (HCI, Heidelberg University and the chair of the EMVA1288 group).
Why is an image sensor not perfect? Or – what effects degrade the signal of a camera?
Explained with a series of direct demonstrations to show the basic degradations: temporal noise, nonuniformity, and dark current.
The basic parameters of the EMVA 1288 standard Release 4 Linear and General
The standard Release 4 covers a much wider range of cameras: linear, non-linear, without and with lens, with preprocessing, and multimodal sensors such as polarization and multspectral imagers. Still a small set of parameters is sufficient to characterize a camera. It is explained how this parameters can quantitatively and in an objective manner describe the quality of cameras. And it is shown how accurately can they be measured.
What you should know about your application to select the best camera for it?
The conditions under which you have to take images, the kind of information you need to extract out of the acquired images and the kind of image processing algorithms used decides which EMVA 1288 parameters are the most critical ones and therefore which camera is the best.
How to perform camera comparison in practice using the EMVA 1288 summary datasheet?
In this webinar we apply what we have learned in the first three webinars. We use the standardized EMVA 1288 summary sheet from several cameras and then study which of the cameras is the best for different real-world application scenarios.
