STROBE Timepoints
GRR Snapshot Timing
To support synchronization of the exposure with external events such as a flash or
mechanical shutter, the MT9P031 produces a STROBE output. By default, this signal is
asserted for approximately the time that all rows are simultaneously exposing, minus the
vertical blanking time, as shown in Figure 23 on page 47 and Figure 24. Also indicated in
these figures are the leading and trailing edges of STROBE, which an be configured to
occur at one of several timepoints. The leading edge of STROBE occurs at STROBE_Start,
and the trailing edge at STROBE_End, which are set to codes described in Table 16.
If STROBE_Start and STROBE_End are set to the same timepoint, the strobe is a
wide pulse starting at the STROBE_Start timepoint. If the settings are such that the
strobe would occur after the trailing edge of FV, the strobe may be only
however, because there is no concept of a row at that time. The sense of the STROBE
