  • Page 30: Binning

    On  digital  cameras,  you  can  find  several  operations  for  progressing  sensitivity.  One  of  them is the so-called "Binning". Here, the charge carriers of neighboring pixels are aggre- gated. 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". In bidirectional binning, a square of neighboring pixels is aggregated.

    2x1 binning takes place within the FPGA of the camera. The binning cor- rection is realized by averaging the pixel values instead of simply adding  them. 11.2 Color Adjustment – White Balance This feature is available on all color cameras of the Baumer HXG series and takes  place within the Bayer processor.

    12.5 "Inter Packet Gap" (IPG) To achieve optimal results in image transfer, several Ethernet-specific factors need to be  considered when using Baumer HXG cameras. Upon starting the image transfer of a camera, the data packets are transferred at maxi- mum transfer speed (1 Gbit/sec). In accordance with the network standard, Baumer em- ploys a minimal separation of 12 Bytes between two packets. This separation is called  "Inter Packet Gap" (IPG). In addition to the minimal PD, the GigE Vision standard stipu- ® lates that  the PD be scalable (user-defined).
