2 Introduction
2.3.1 MV1-D2048x1088-HS01 Region of Interest
The binning block is of special interest in the MV1-D2048x1088-HS01-96-G2-10 camera. A
possible configuration to detect all the 128 bands on the whole sensor width is shown in Table
2.2. The advantage of using vertical binning is the high frame rate (see also Table 2.3) and the
availability of only one value per band for every column.
There are possibilities to increase the frame rate even more:
• The "Multiple Regions of Interest (MROI)" feature can be used to choose only the bands
of interest. Reading out fewer rows increases the frame rate in all pixel formats.
• Horizontal resolution can be reduced by choosing a smaller width or by using horizontal
binning. Note that this does not increase the frame rate for pixel format Mono8 if
BinningVertical=8 is used, as sensor is already read out at full speed. In all other pixel
formats this increases the frame rate.
The property
Height
specifies the height at the image output. Example:
Bin-
ningVertical =8 and Height =128: height of output image is 128; Height on sensor
before binning is 1024 (8*128). The MROI_H and MROI_Htot settings on the other
hand, specify the height on the sensor before binning.
