Electronic Shutter Exposure Control
shutter's exposure duration (integration time) is pro-
grammed via the two-wire serial interface. The
MT9V403 shutter can be operated to generate continu-
ous video output (simultaneous master mode or
sequential master mode) or capture single images
(snapshot mode).
shot mode is 2 row times. With a 66 MHz SYSCLK the
minimum integration time is 20µs (10µs row time ±2
rows). The maximum integration time is either is 256

or interlaced scan modes. Progressive scan is the
default mode. In the interlace scan mode there are two
readout options. The frame synchronization wave-
forms for interlaced scanning are shown in Figure 27,

integration time is limited by the inverse of the frame
rate because one cannot integrate longer than a frame
time. With a 66 MHz clock and full resolution (502
rows) the maximum integration time is 5ms
(= 1/200 fps). In sequential master mode or snapshot
mode the maximum integration time is limited to 256
frame times. Table 5 shows some examples of how the
maximum integration time changes with resolution
and clock speed.
which shows alternating readout of the even-num-
bered and odd-numbered rows in consecutive frames.
There is also an option that allows sequential readout
of only the odd or even rows of a frame (effectively a X2
vertical subsampling of the image).
