Introduction and Motivation

The OEM camera modules support user specific vision system designs and especially embedded
solutions. Other than in Photonfocus cameras and board level cameras the OEM camera
modules are not complete vision components. The user has to solve the interfacing to his own
electronic solution to get a complete vision solution. From this target some restrictions arise.
One restriction is that Photonfocus can not guarantee the correct function of the complete
solution. Due to the open architecture of the OEM modules excessive support is often needed
to implement the modules in advanced embedded solutions. Under defined boundary
conditions Photonfocus provides this service on contract base. The OEM modules are not
intended for the use in single volumes. The threshold in volume is from 100 modules and more
per year. Long term contracts with the customer ensure the availability of the modules over a
long period to predictable production dates.
For low volume projects please refer to our board level or camera products. These products are
complete vision products that include the software. Due to the character of the board level
and camera products Photonfocus can guarantee for the quality and functionality of these
complete vision products.
The use of the OEM camera modules enables the use of the Photonfocus camera firmware and
software. Thus the user‘s own vision system benefit from these concepts. Modifications in the
firmware can be made on request on contract base. This applies also to modifications in the
Photonfocus software. The user can set up his own software on the base of the PFRemote SDK.
The Photonfocus software itself is platform independent and was already ported to different
operating systems and embedded solutions.
The control of the camera modules over a low level protocol without the help of a CPU is not
supported. The advanced features in Photonfocus E-series products, like LinLog and FPN
correction, require complex control sequences. If user‘s applications require camera module
control over low level commands then only products from the classic Photonfocus product
range are to be considered. Please contact the Photonfocus Support for further consultance.
The idea of the OEM modules is to give the user a very easy to use environment for the own
development. This is supported with the interface definition on the output of the modules.
This interface definition is identically applied to all Photonfocus OEM modules and is based on
the well known AIA interface definition for vision systems. The camera modules permit the
direct interfacing without any background information of the camera electronic. To reach this
goal the modules are sold only with digital interface. This leads to one or two PCB solutions
(see Table 2.1).
