Description
bExposureMode
0x1080
R/W
C
0x00
0x00 = AUTOMATIC_MODE
0x01 = COMPILED_MANUAL_
MODE - The desired exposure time is set
manually in the Manual Exposure registers
and the exposure parameters are
calculated by the algorithm.
0x02 = DIRECT_MANUAL_
MODE - The exposure parameters are
input directly.
0x03 = FLASHGUN_MODE -
The exposure parameters are set manually.
bExposureMetering
0x1082
R/W
C
0x00
Weights associated with the zones to
calculate the mean statistics. Exposure
Weight is Centered or Backlit or Flat.
0x00 = ExposureMetering_flat - Uniform
gain associated with all pixels
0x01 = ExposureMetering_backlit: more
gain associated with centre and bottom
pixels
0x02 = ExposureMetering_centred - more
gain associated with centre pixels
bManualExposure
Time_Num
0x1084
R/W
I
0x01
Exposure Time for Compiled Manual Mode
in seconds. Numerator / Denominator gives
required exposure time
bManualExposure

0x00
Exposure Compensation - a user choice for
setting the runtime target. A unit of
exposure compensation corresponds to 1/6
EV. This is a signed register.

0x01 = True
fpUserMaximum
IntegrationTime (MSB)
0x10b7
R/W
M F
0x64
User Maximum Integration Time in
microseconds. This control takes in the
maximum integration time that host would
like to support. This in turn gives an idea of
the degree of “wobbly pencil effect”
acceptable by Host.
