Combine sequences (HDR)
In order to improve the accuracy of distance data, the camera features the ability to combine 2 frames from
the ToF sensor into one frame with improved accuracy. It uses the confidence values of the 2 input frames to
calculate a new distance value for each pixel of the output frame.
The following registers are used to configure Combine mode:
NofSequ
:
To configure 2 sequences
IntegrationTime
, IntTimeSeq1:
To configure integration times of the 2 sequences
ModulationFrequency
, ModFreqSeq1:
To configure modulation frequencies of the 2 sequences
ImgProcAdvanced
, bit 0: To enable combine mode

Camera Coordinate System
The default coordinate system starts pixel numbering in the upper left corner of the pixel array, seen from the
camera’s point of view. Also note the directions of X, Y, and Z coordinates (In XYZ image modes).

Note
If you are working with a
BltTofApi
library, or the
BltTofSuite
, the camera coordinate system
is automatically converted. Please refer to
BltTofApi
documentation for the coordinate
system (See chapter 8).

Camera Data Format
The camera provides up to four data channels via its data interface. The meaning of each data channel
depends on the selected data format. The factory default setting provides an array of distance data and an
array of amplitude data.
