SNAPSHOT MODE
When a TRIGGER is generated, the sensor will enter the SNAP
state as shown in figure 24.
6.1 Introduction
snapshot
Two dedicated pins are provided on the KAC-9617, snapshot ,
and extsync allowing the sensor to be externally controlled to
capture a single image.

Circuit
TRIGGER
The snapshot input pin is used to trigger a snapshot, while the
extsync output pin is used to synchronize a light source, strobe
or mechanical shutter.
6.2 Taking a Snapshot
By default the sensor will operate in the VIDEO state (see figure
24). To take a snapshot, the snapshot mode must be enabled by
setting the SnapEnable bit in the SNAPSHOTMODE register to
a logic 1. This will cause the sensor to enter the FREEZE state
at the end of the current frame. In the FREEZE state the sensor
is idle.
The sensor will leave the FREEZE state and return to VIDEO
state when the snapshot mode is disabled ( SnapEnable bit in
the SNAPSHOTMODE register set to a logic 0)

6.3 The SNAP State in External Shutter Mode
To take a snapshot in external shutter mode, the ShutterMode
bit of the SNAPSHOTMODE register must be set.
In this mode three consecutive operations will be carried out in
the SNAP state as follows (see figure 23a):
? Array Reset , during which the extsync pin is kept in-active
and the array is reset one row at a time. The number of times
the array is reset is programmable from 1-3 frames, (see the
SsFrames bits in the SNAPSHOTMODE register).
? Image Capture , the extsync pin will activate. The width of the
extsync signal can be programed from 1 to 2047 lines by pro-
gramming the integration time registers, ITMEH and ITIMEL.
? Array Read Out , the third and final operation reads the image
data out one row at a time.

6.4 The SNAP State in Normal Mode (default)
To take a snapshot in normal mode, the ShutterMode bit of the
SNAPSHOTMODE register must be cleared. In this case the fol-
lowing consecutive operations will be carried out in the SNAP
state (see figure 24b):
? Array Reset , during which the extsync pin is kept in-active
and the array is reset one row at a time. The number of times
the array is reset is programmable from 1-3 frames, (see the
SsFrames bits in the SNAPSHOTMODE register).
? Image Capture , the extsync pin will activate and remain
active for the duration of the capture time. The width of the
image capture can be extended by programming FDELAYH
Figure 24. Snapshot Mode
Alternatively, when an active snapshot signal is applied to the
snapshot input pin an internal trigger signal, TRIGGER , is gen-
erated as shown in figure 25. The trigger generation circuit will
create two types of TRIGGER as follows:
? Pulse Trigger ( SnapshotMode bit of the SNAPSHOTMODE
register is cleared). In this mode (the default) a single TRIG-
GER pulse will be generated.
? Level Trigger ( SnapshotMode bit of the SNAPSHOTMODE
register is set). In this mode the TRIGGER will remain high as
long as an active level is held on the snapshot pin.
and FDELAYL, which will increase integration time.
? Array Read Out , the image data is read out one row at a
time. During this operation the extsync pin remains active.
6.5 Return to the FREEZE State
When read out is complete the sensor will return to the FREEZE
state.
6.6 Return to the VIDEO state
If the snapshot mode is disabled before readout is complete
( SnapEnable bit in the SNAPSHOTMODE register is set to a
logic 0), then at the end of readout the sensor will return to the
VIDEO state.
