8.2.2 Trigger Mode After a specified external event (trigger) has occurred, image acquisition is started. De- pending on the interval of triggers used, the camera operates non-overlapped or over- lapped in this mode. With regard to timings in the trigger mode, the following basic formulas need to be taken into consideration: Case Formula earliestpossibletrigger(n+1) readout(n) -

Page 29: Camera Functionalities
A digital camera usually delivers image data in at least one format - the native resolution of the sensor. Baumer cameras are able to provide several image formats (depending on the type of camera). Compared with standard cameras, the image format on Baumer cameras not only in- cludes resolution, but a set of predefined parameter. These parameters are: ▪ Resolution (horizontal and vertical dimensions in pixels) ▪... -

These values can be adjusted by the user. Notice The LUT always calculates with 12 bit input and 12 bit output. In 8/10 bit mode, the lower bits of the input values are equal zero but can be spread to full 12 bit because of digital gain. Therefore, all values of the LUT have to be filled in. ... -

10.1.7 Gamma Correction With this feature, Baumer LXC cameras offer the possibility of compensating nonlinearity in the perception of light by the human eye. For this correction, the corrected pixel intensity (Y') is calculated from the original intensity of the sensor's pixel (Y ) and correction factor γ using the following formula (in over- original simplified version):... -
Page 35: Normal- Roi Readout (Region 0)
10.1.8.1 Normal- ROI Readout (Region 0) For the sensor readout time of the ROI, the horizontal subdivision of the sensor is unim- portant – only the vertical subdivision is of importance. Notice The activation of ROI turns off all Multi-ROIs. Start ROI End ROI ROI: Readout The readout is line based, which means always a complete line of pixels needs to be read out and afterwards the irrelevant information is discarded. -
Page 36: Binning
"Binning". Here, the charge carriers of neighboring pixels are ag- gregated. Thus, the progression is greatly increased by the amount of binned pixels. By using this operation, the progression in sensitivity is coupled to a reduction in resolution. Baumer cameras support three types of Binning – vertical, horizontal and bidirectional. In unidirectional binning, vertically or horizontally neighboring pixels are aggregated and reported to the software as one single "superpixel". -
Page 37: Decimation (Sub-Sampling)
10.1.11 Decimation (sub-sampling) In this mode, the sensor is read out partially. Thus the frame rate is increased and the amount of data transferred is reduced. It is available for mono and color cameras. With color cameras, a color correct readout of the pixels takes place. -

Super pixel carriers from four pixels in bidirectional binning. 10.2 Color Adjustment – White Balance This feature is available on all color Baumer LXC cameras and takes place within the Bayer processor.

Page 53: Camera Link Interface
Camera Link Interface ® The Camera Link interface was specifically developed for cameras in machine vision ap- ® plications and provides high transfer rates and low latency. Depending on the configura- tion (Base, Medium or Full) the transfer rate adds up to 850 MBytes/sec. Cameras of the Baumer LXC series are equipped with a Camera Link Full interface and ® therewith able to transmit up to 850 MBytes/sec. 11.1 Channel Link and LVDS Technology Camera Link bases upon the Channel Link technology, but provides a specification, that ® ® is more beneficial for machine vision. Channel Link in turn is an advancement of the LDVS (Low Voltage Differential Signaling) ® standard – a low power, high speed interface standard. -
