Figure 10. Basic Readout Timing
SYNC_YR is not identical to as SYNC_YL. SYNC_YR is used
in case of electronic shutter operation. The CLK_YR is driven
identically as CLK_YL, but the SYNC_YR pulse leads the
SYNC_YL pulse by a certain number of rows. This lead time
is the effective integration (electronic shutter ~) time. Relative
to the row timing, both SYNC pulses are given at the same
time position, once for each frame, but during different rows.
SYNC_YL is pulsed when the first row is read out and
SYNC_YR is pulsed for the electronic shutter to start for this
first row. CAL is pulsed on the first row too, 2
s later than
SYNC_YL.
The minimal idle time is 1.4
s (before starting reading pixels).
However, do not read out pixels during the complete row initial-
ization process (in between the rising edge on S and the falling
edge on L/R). In this case, the total idle time is minimal. This
timing assumes that the Y start register was loaded in
advance, which can occur at any time but before the pulse on
SYNC_YL or SYNC_YR.
