AutomaticFrameRateControl⁽¹⁾
bFrameRateMode
0x0d80
Default value
Purpose
Type
Possible values
0x00
Defines the mode in which the framerate of the system would work
<0> Manual - the system uses the values programmed into the
StaticFrameRateControl registers
<1> Auto - the system automatically adjusts the framerate between the
bUserMinimumFrameRate_Hz and bUserMinimumFrameRate_Hz.
bImpliedGainThresholdLow_num
0x0d82
Default value
Purpose
Type
0x02
Numerator for calculation of low threshold of autoframerate control
BYTE
bImpliedGainThresholdLow_den
0x0d84
Default value
Purpose
Type
0x02
Denominator for calculation of low threshold of autoframerate control.
BYTE
bImpliedGainThresholdHigh_num
0x0d86
Default value
Purpose
Type
0x02
Numerator for calculation of High threshold of autoframerate control
BYTE
bImpliedGainThresholdHigh_Den
0x0d88
Default value
Purpose
Type
0x02
Denominator for calculation of high threshold of autoframerate control
BYTE
bUserMinimumFrameRate_Hz
0x0d8a
Default value
