MT9V024: 1/3-Inch Wide-VGA Digital Image Sensor

Feature Description

Figure 15:

Simultaneous Master Mode Synchronization Waveforms #2

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.

Sequential Master Mode

In sequential master mode the exposure period is followed by readout. The frame

synchronization waveforms for sequential master mode are shown in Figure 16. The

frame rate changes as the integration time changes.

Snapshot Mode

In snapshot mode the sensor accepts an input trigger signal which initiates exposure,

and is immediately followed by readout. Figure 17 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 MT9V024. The integration

time is preprogrammed at R0x0B or R0xD2 through the two-wire serial interface. After

the frame's integration 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
