Slave Mode
In slave mode, the register values of res_length and tint_timer are ignored. The integration time is controlled by the int_time pin. The
relationship between the input pin and the integration time is shown in
array goes out of reset and exposure can begin. When int_time goes low again and the desired exposure time is reached, the image
is sampled and read out can begin.
Changing a pixel's reset level during line readout might result in image artefacts during a small transient period. As a result, it is advised
to only change the value of int_time during ROT.
Triggered Shutter
The two main differences in the pipelined shutter mode are:
■
■
This means that for every frame, you need to manually intervene. The pixel array is kept in reset state until you assert the int_time
input. Similar to the pipelined shutter mode, there is a master mode in which the sequencer can control the integration time, or a slave
mode in which you can define the integration time.
The possible applications for this triggered shutter mode are:

One single image is read upon every user action.
Integration (and read out) is under control of the user through pin int_time.
