Camera modes of operation
The above modes are interrupted by the detection of a USB or RS232 connection. This is to allow for the possibility that the PC
driver takes control of the chipset (e.g. when starting a VfW application through USB).
3.1
Standby mode (or USB suspend mode)
3.1.1
The camera enters standby mode automatically after 30 seconds of inactivity if not tethered to USB, or when USB suspend mode
is activated by the PC driver.
Entering this mode
3.1.2
This allows image data to be stored in memory with extremely low power consumption, which appears to the user as if the
camera is switched ‘off’, since there is no LCD display or LED lit. In VV6444-based designs, STV0680A powers off the sensor
completely, in VV6410/6500 based designs, the sensor is placed in suspend mode, and the camera enters a mode where only
SDRAM refresh is carried out. The shutter button is inactive in standby mode.
Description
3.1.3
Wake-up from standby mode is achieved by any of the following means:
Exiting this mode
1. Pressing the ‘mode’ button (only if no USB detected)
Mode
If shutter button pressed while in
this mode
If mode button
pressed while in this
mode
If no further
action

mode
No function - pictures cannot be taken in
standby mode
Wakes up camera into
‘Snapshot’ mode
Remains in
standby mode
(Display is
blank)
’Snapshot’
mode
Takes one picture, if sufficient light availa-
ble, then returns to ‘Snapshot’ mode
Moves to continuous cap-
ture mode
Stays in ‘Snap-
shot’ mode for
30 seconds then
moves to
standby mode

Takes a picture every 80mS while button
pressed, regardless of light available, then
returns to ‘Snapshot’ mode
Moves to self timer mode
Returns to
‘Snapshot’ mode
after 5 seconds
Number of pic-
tures still avail-
able to take
Self timer
Takes one picture after a 10 second count-
down, if sufficient light available, then
returns to ‘Snapshot’ mode
Moves to ‘Clear camera’
mode
“St”
’Clear

(1st press:)
Prompts user to

(2nd press:) Clears all
images stored in cam-
era, then returns to
‘Snapshot’ mode
Moves to ‘Change resolu-
tion’ mode (see note)
“CL”
’Change
resolution’
Changes resolution (i.e. Low to High, or
High to Low) and returns to ‘Snapshot’
mode
Returns to ‘Snapshot’
mode
If currently in
Low Resolu-
tion: “Hr”
If currently in
High resolu-
tion: “Lr”
Table 6 : Camera modes
Note: In STV0680-001, pressing the Mode button while in ‘Clear Camera’ mode only moves onto ‘Change resolution’ mode if the
camera has no images stored. This is because in STV0680-001, mixed resolutions (i.e. ‘High’ and ‘Low’) cannot be stored at the
same time. In STV0680A-002, mixed resolutions can be stored at the same time.
