MT9V022: 1/3-Inch Wide-VGA Digital Image Sensor
Feature Description
Feature Description
Operational Modes
The MT9V022 works in master, snapshot, or slave mode. In master mode the sensor
generates the readout timing. In snapshot mode it accepts an external trigger to start
integration, then generates the readout timing. In slave mode the sensor accepts both
external integration and readout controls. The integration time is programmed through
the two-wire serial interface during master or snapshot modes, or controlled via exter-
nally generated control signal during slave mode.
Master Mode
There are two possible operation methods for master mode: simultaneous and sequen-
tial. One of these operation modes must be selected via the two-wire serial interface.
Simultaneous Master Mode
In simultaneous master mode, the exposure period occurs during readout. The frame
synchronization waveforms are shown in Figure 13 and Figure 14. The exposure and
readout happen in parallel rather than sequential, making this the fastest mode of oper-
ation.
