ERS Snapshot Timing
The first trigger is by default automatic, producing continuous images. If snapshot is set,
the first trigger can either be a low level on the TRIGGER pin or writing a “1” to the
trigger register field. If Invert_Trigger is set, the first trigger is a high level on TRIGGER
pin (or a “1” written to trigger register field). Because TRIGGER is level-sensitive,
multiple frames can be output (with a frame rate of
the triggering level.
The second trigger is also normally automatic, and generally occurs SW row times after
the exposure is started. If Bulb_Exposure is set, the second trigger can either be a high
level on TRIGGER or a write to Restart. If Invert_Trigger is set, the second trigger is a low
level on TRIGGER (or a Restart). In bulb modes, the minimum possible exposure time
depends on the mechanical shutter used.
After one frame has been output, the chip will reset step 1, above, eventually waiting for
the first trigger again. The next trigger may be issued after ((VB - 8) x
modes or
The choice of shutter type is made by Global_Reset. If it is set, the GRR shutter is used;
otherwise, ERS is used. The two shutters are described in “Electronic Rolling Shutter” on
page 45 and “Global Reset Release” on page 45.
The default ERS continuous mode is shown in Figure 8 on page 13. Figure 23 shows
default signal timing for ERS snapshot modes, while Figure 24 on page 48 shows default
signal timing for GRR snapshot modes.
