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 Figure 14. When the input pin int_time is asserted, the pixel

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.

Figure 14. Integration and Image Readout in Slave Mode

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:

■ One single image is read upon every user action.

■ Integration (and read out) is under control of the user through pin int_time.

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:

■ Synchronize external flash with exposure

■ Apply extremely long integration times (only in slave mode)
