Sensor integration time can be changed by adjusting the amount of time the pixels are
set to collect charge generated from light. The sensor also supports sub-row integration
time for fine control of pixel integration time.
Note that not all integration times may be desired under certain lighting conditions. If
the light source has a flicker component, then the integration time needs to be set prop-
erly to avoid banding in the image.
There are two important signals used for snapshot mode: TRIGGER and STROBE. The
TRIGGER signal initiates the start of a single-frame capture, and STROBE is an output
pulse that may be used to turn on a flash and/or activate a mechanical shutter.
An external trigger signal input allows the snapshot operation to begin after the
TRIGGER pulse moves from a HIGH to LOW state. Alternately, an internal register can
be set through the serial inteface.
After the TRIGGER pulse has signaled a snapshot operation, each row of the imager
array is reset in sequence to clear out any accumulated signal. Once each row of the
imager is reset, the STROBE pulse is output from the imager
In addition to the standard snapshot mode, the MT9T031 has a global shutter release
mode which may be combined with a mechanical shutter to achieve simultaneous
exposure of all rows in the image. Two global shutter modes are available: programmed
exposure and bulb mode.
Row and column skip modes use subsampling to reduce the output resolution without
reducing the field of view. The MT9T031 also has row and column binning modes, which
can reduce the impact of aliasing introduced by the use of skip modes. Both 2X and 3X
binning modes are supported. Rows and columns can be binned independently.
With the flexible windowing capability of the sensor, the user is able to read out different
resolution formats from default of QXGA to UXGA, SXGA, XGA, SVGA, VGA, CIF, QVGA,
QCIF, and so on.
