5.  MODES OF OPERATION 

The camera can operate in two possible operating modes.  

 

 

See paragraph 4.2.17- for more information on the camera operating modes 

5.1 Continuous modes 

The continuous mode is the most basic mode of operation. In continuous mode the camera captures images with an 
integration period and a frame period set by the user. 

5.2 Control mode 

The control mode is a fully asynchronous operating mode. The CC1 pulse is used as an external signal to control the 
image capture process.   
In control mode a rising edge of CC1 starts a shutter operation (SH) that resets the light sensitive image pixels. A 
falling edge on CC1 starts the image transfer (ITR) followed by the readout of the integrated image in the desired 
image format. The timing of the control mode is the below.
