Currently the FRAME_REQ signal to the image sensor is linked to the HDMI output sequencer. This means frame read out and exposure do not overlap.

In continuos mode the FRAME_REQ signal is held high and this causes the image sensor to acquire new frames as fast as possible also allowing an overlap of exposure and readout. This causes artefacts to be visible in the read out image which we want to analyse.

This requires the events (matrix) to be configured differently and changes to the sequencer.
