When exposure time is greater than the sum of vertical blank and window height, the
number of vertical blank rows is increased automatically to accommodate the exposure
time.
In sequential master mode the exposure period is followed by readout. The frame
synchronization waveforms for sequential master mode are shown in Figure 15. The
frame rate changes as the integration time changes.
In snapshot mode the sensor accepts an input trigger signal which initiates exposure,
and is immediately followed by readout. Figure 16 shows the interface signals used in
snapshot mode. In snapshot mode, the start of the integration period is determined by
the externally applied EXPOSURE pulse that is input to the MT9V032. The integration
time is preprogrammed via the two-wire serial interface on R0x0B. After the frame's inte-
gration period is complete the readout process commences and the syncs and data are
output. Sensor in snapshot mode can capture a single image or a sequence of images.
The frame rate may only be controlled by changing the period of the user supplied
EXPOSURE pulse train. The frame synchronization waveforms for snapshot mode are
shown in Figure 17.
