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

Feature Description

the user supplied EXPOSURE pulse train. The frame synchronization waveforms for

snapshot mode are shown in Figure 18 on page 20. Additional details on this mode can

be found in TN-09-225 Snapshot Exposure Mode Operation.

Slave Mode

In slave mode, the exposure and readout are controlled using the EXPOSURE,

STFRM_OUT, and STLN_OUT pins. When the slave mode is enabled, STFRM_OUT and

STLN_OUT become input pins.

The start and end of integration are controlled by EXPOSURE and STFRM_OUT pulses,

respectively. While a STFRM_OUT pulse is used to stop integration, it is also used to

enable the readout process.

After integration is stopped, the user provides STLN_OUT pulses to trigger row readout.

A full row of data is read out with each STLN_OUT pulse. The user must provide enough

time between successive STLN_OUT pulses to allow the complete readout of one row.

It is also important to provide additional STLN_OUT pulses to allow the sensors to read

the vertical blanking rows. It is recommended that the user program the vertical blank

frames by delaying the application of the STFRM_OUT pulse.
