Global Reset Release (GRR) Snapshot Mode for MT9T001 Sensor (3Mpixels)
To setup the GRR Snapshot mode, follow the procedure described in the MT9T001
sensor data sheet. In addition, to enable the GRR mode, the application should set bit 2
of Altera register R0 to ’1’ in FPGA logic.
Note:
It is necessary to reverse all changes before switching to video or Rolling Shutter snapshot modes.
Refer to Q37-GRR.GIF for explanation of control signals available at the external trigger
connector.
Strobe signal in different revisions of MT9T001 3Mp sensors is the following:
●
rev.5649 - Strobe signal is present in both rolling and GRR snapshot modes
●
rev.5665 - Strobe signal is present only in GRR snapshot mode
