                                        Figure 6.  Required Settings for Non-Overlap Mode Operation 

 

 

Example:  

Non-Overlap 

Mode 

Operation in Non-Overlap mode is illustrated in the timing diagram below. In this example, 
the exposure time is 10 ms and the readout time is 29.5 ms. The total time to take 3 frames is 
118.5 ms (3 

 10 ms + 3



 29.5 ms), equivalent to a frame rate of 25.3 fps (3 frames 

 0.1185 

seconds).  

Note: The exposure and readout times listed are for illustration purpose only. Actual values may vary.  
Refer to the product data sheet for the actual readout times. 

 

Figure 7.  Timing Diagram for Non-Overlap Mode 

Referring to figure 7, it can be seen that exposure and readout are carried out in non-
overlapped fashion. As a result, each frame in the sequence is precisely exposed for the time 
specified (i.e. 10 ms). 

Select these parameters to 

operate your Evolve 512 

camera in Non-Overlap 

mode.
