Free running mode 

 
 

The pre-installed free running mode allows images to be acquired without external 
control signals. The sensor will be read out after the set integration time; then the sensor 

will be reset. Following this, integration starts again and the readout of the image 
information begins afresh. The data are output on the rising edge of the pixel clock. The 

signals FRAME_VALID (FVAL) and LINE_VALID (LVAL) mask valid image information. The 
signal SHUTTER indicates the active integration phase of the sensor. The number of clock 
pulses after exposure 

CPRE

 is defined by the calculation of the frame time (see 9).
