3.5 Subwindowing, Subsampling & Binning
Subwindowing, also known as region of interest (ROI), is the ability of the camera to output a smaller image size
(subwindow) than the whole imager array. An imager that supports a maximum resolution of 1280 x 1024 pixels for
example, could output a subwindow of 640 x 480 pixels with the subwindow being positioned nearly anywhere inside the
1280 x 1024. The subwindow is actually a smaller field of view than the maximum resolution available. There are
limitations on the granularity of the subwindow size and on its position within the whole array. The granularity is 8 pixels.
Subsampling, also known as decimation, is the throwing away of every n
th
pixel or pixel pair in the image in the X and/or
Y directions. For example, an imager with a maximum resolution of 1280 x 1024 could throw away every second pixel in
both the X and Y directions and output an image that is 640 x 512 pixels, yet covers the same field of view of the original
full resolution. Not all cameras support Subsampling. Those that do may support subsample levels of 2, 4 or 8. Some
cameras even allow different Subsampling in the X vs. the Y directions.
Binning is similar to Subsampling, except instead of throwing pixels away, pixel values are combined in some fashion.
They can be either summed (to provide greater sensitivity) or averaged (to reduce noise). The resulting resolution would
be the same as for Subsampling, but the data from every pixel is used. Several cameras support Binning with binning
levels up to 8 by 8.
It is important to note that certain camera models do work in multi-tap configuration to give better speed performance
and this need to be taken in consideration when working with sub window, subsampling or binning mode.
3.6 External I/O Interface
3.6.1 Standard LuCam Camera GPI/O Interface Description
For board-level cameras, the External Interface Header can be found in the corner of the PCB next to the silver USB
connector. For enclosed cameras, it is found on the side of the camera near the USB connector. It is a male, 2 mm
pitch, 16-pin (2 x 8) header. The pin numbering can be seen in Figure 26.
