4.2.3.1.
Binning
When binning is applied, the image is divided into cluster of k
×
k pixels, where all pixel values in each cluster are summed or
averaged and treated as one output pixel. For example, a 2
×
2 binning produces 2
×
2 pixel clusters and results in images with 1/2
of the original horizontal and vertical resolution.
4.2.3.2.
Skipping/Decimation
When skipping is chosen, only every n-th pixel is used to create the output image.
For example, with a 2
×
2 skipping the sensor is divided into 2x2 pixel arrays, and only on pixel of the array is read and
transmitted, the rest are discarded. Skipping/Decimation is usually faster than binning mode, but also introduces more aliasing
effects.

Color and Mono Modes
All modes are provided by the xiAPI or standard interfaces using the xiAPI (please see section
Each xiMU cameras supports several mono (black-and-white) output modes.
Mode
Description
RAW8
Raw sensor data, 8 Bit per pixel, single channel
RAW16
Raw sensor data, 16 Bit per pixel, single channel
10 or 12 Bit sensor output (LSB)
MONO8
Intensity output, 8 Bit per pixel, single channel
MONO16 Intensity output, 16 Bit per pixel, single channel
table 4-1, image formats, mono
Color camera models also support additional color modes.
Mode
Description
RGB24
RGB filtered output, 24 Bit per pixel, 3 channels
Sequence: [Blue][Green][Red]
RGB32
RGBA filtered output, 32 Bit per pixel, 4 channels, Alpha channel
equals 0. Sequence: [Blue][Green][Red][0]
RGB_PLANAR RGB filtered output with planar-oriented channels.
Format: [R][R]...[G][G]...[B][B]...

Note1: For color modes RGB32 and RGB24 the image from sensor needs to be pre-processed (de-bayering). CPU load is higher
in these modes. Setting this parameter will reset current region of interest. RGB24 is being processed from the RGB32 by
removing the unused Alpha channel creating a slightly higher CPU load then the RGB32 format.
