JPEG Indirect Registers
Micron Confidential and Proprietary
7 sharedParams.aeContBuff uchar 8 RW
Weighting factor determining to what extent AE
driver averages luma over time in continuous AE
mode. Setting of 32 disables luma averaging—only
current luma values are used. Lower settings enable
luma averaging.
8 sharedParams.aeContStep uchar 2 RW
Number of steps in which AE driver is expected to
reach target brightness in continuous AE mode.
9 sharedParams.aeFastBuff uchar 32 RW
Weighting factor determining to what extent AE
driver averages luma over time in fast mode. Setting of
32 disables luma averaging—only current luma values
are used. Lower settings enable luma averaging.
10 sharedParams.aeFastStep uchar 1 RW
Number of steps in which AE driver is expected to
reach target brightness in fast AE mode.
11 sharedParams.awbContBuff uchar 8 RW
Weighting factor determining to what extent AWB
driver averages luma over time in continuous AWB
mode. Setting of 32 disables luma averaging—only
current luma values are used. Lower settings enable
luma averaging.
12 sharedParams.awbContStep uchar 2 RW
Number of steps in which AWB driver is expected to
reach target color balance in continuous AWB mode.
13 sharedParams.awbFastBuff uchar 32 RW
Weighting factor determining to what extent AWB
driver averages luma over time in fast mode. Setting of
32 disables luma averaging—only current luma values
are used. Lower settings enable luma averaging.
14 sharedParams.awbFastStep uchar 1 RW
Number of steps in which AWB driver is expected to
reach target color balance in fast AWB mode.
18 sharedParams.totalMaxFrames uchar 30 RW
Number of frames after which every driver must time
out.
19 sharedParams.flashTH uchar 0 RW
Exposure value (EV) threshold. If current EV is below
this threshold, flash is used in autoevaluate flash
mode.
20 sharedParams.outdoorTH uchar 10 RW
Exposure value (EV) threshold. If current EV is above
this threshold and bit 5 of seq.mode equals 1, AWB
driver is forced to choose color correction settings
suitable for daylight color temperature of 6500 K.
21 sharedParams.LLmode uchar 0x60 RW
Bit 0
—change interpolation threshold
Bit 1
—reduce color saturation
Bit 2—reduce aperture correction
Bit 3
—increase aperture correction threshold
Bit 4
—enable Y filter
22 sharedParams.LLvirtGain1 uchar 0x51 RW
Min. LL virtual gain. Defined as (ae.VirtGain/2 +
ae.DGainAE1/16 + ae.DGainAE2/4).
23 sharedParams.LLvirtGain2 uchar 0x5A RW
Max. LL virtual gain. Min. and max. LL virtual gains
define when low-light parameters start and stop
changing.
24 sharedParams.LLSat1 uchar 128 RW
Max. color saturation for color correction matrix (128
means 100%).
25 sharedParams.LLSat2 uchar 0 RW
Min. color saturation
26 sharedParams.LLInterpThresh1 uchar 16 RW
Min. threshold for interpolation
27 sharedParams.LLInterpThresh2 uchar 64 RW
Max. threshold for interpolation
