Functionality
This chapter serves as an overview of the camera configuration modes and explains camera
features. The goal is to describe what can be done with the camera. The setup of the camera is
explained in later chapters.
4.1 Image Acquisition
4.1.1 Readout Modes
The MV-D1024E-3D01-160 camera provides two different readout modes:
Sequential readout:
Frame time is the sum of exposure time and readout time. Exposure time of the next image
can only start if the readout time of the current image is finished.
Simultaneous readout (interleave):
The frame time is determined by the maximum of the exposure time or of the readout time,
which ever of both is the longer one. Exposure time of the next image can start during the
readout time of the current image.

Table 4.1: Readout modes of the MV-D1024E-3D01-160 camera
Fig. 4.1 illustrates the effect on the frame rate when using either the sequential readout mode
or the simultaneous readout mode (interleave exposure).
Sequential readout mode:
For the calculation of the frame rate only a single formula applies: frames per second equal to
the invers of the sum of exposure time and readout time.
Simultaneous readout mode (exposure time < readout time):
The frame rate is given by the readout time. Frames per second equal to the invers of the
readout time.
Simultaneous readout mode (exposure time > readout time):
The frame rate is given by the exposure time. Frames per second equal to the invers of the
exposure time.
The simultaneous readout mode allows to achieve a higher frame rate. However, if the
exposure time strongly exceeds the readout time, then the effect on the frame rate is
neglectable.
