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
MV1-D1312(I) series cameras is explained in later chapters.

Image Acquisition
4.1.1
Readout Modes
The MV1-D1312(I) CMOS cameras provide 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 mode of MV1-D1312 Series camera
The following figure illustrates the effect on the frame rate when using either the sequential
readout mode or the simultaneous readout mode (interleave exposure).

f p s = 1 / r e a d o u t t i m e
f p s = 1 / e x p o s u r e t i m e
f p s = 1 / ( r e a d o u t t i m e + e x p o s u r e t i m e )
e x p o s u r e t i m e < r e a d o u t t i m e
e x p o s u r e t i m e > r e a d o u t t i m e
e x p o s u r e t i m e = r e a d o u t t i m e

Sequential readout mode
For the calculation of the frame rate only a single formula applies:
frames per second equal to the inverse of the sum of exposure time and readout time.
