Sequencer
Table 11: Driver Variables−Sequencer Driver (ID = 1)
Offs Name Type Default RW Description
0 vmt void* 61547 RW
Reserved
2 mode uchar 0x0F RW
Set of 1-bit switches enabling various drivers and
outdoor white balance option. Writing 1 to a
particular switch enables the corresponding driver or
option.
Bit 0
—Auto exposure driver (ID = 2)
Bit 1—Flicker detection driver (ID = 4)
Bit 2—Auto white balance driver (ID = 3)
Bit 3
—Histogram driver (ID = 11)
Bit 4—Auto focus driver (ID = 5)
Bit 5
—Option to force outdoor white balance settings
if exposure value exceeds sharedParams.outdoorTH
threshold.
Bits 6:7
—New AF scheme that improves performance
with noise dominated windows.
Bit 7
—TBD
3 cmd uchar 0 RW
Command or program to execute
0
—Run
1
—Do Preview
2—Do Capture
3—Do Standby
4
—Do lock
5—Refresh
6—Refresh mode
Writing a positive value to this variable commands the
sequencer to execute the corresponding program. The
sequencer resets cmd to 0, executes the program, and
then resumes running in its current state.
4 state uchar 3 R
Current state of sequencer
0
—Initialize
1
—Mode Change to Preview
2
—Enter Preview
3
—Preview
4—Leave Preview
5
—Mode Change to Capture
6—Enter Capture
7
—Capture
8
—Leave Capture
9—Standby
5 stepMode uchar 0 RW
Step-by-step mode for sequencer
Bit 0
—Step mode On/Off (1 = On)
Bit 1
