Calculate exposure time from value
Shutter Speed[sec] = OFF_VALUE × 0.99
(nnnn)
Exp)
Value:nnnn = 0078h (for HV-F31CL)
Exposure time = (1/30) × 0.99
(78h)
≒
1/100(sec)
2) In the case that shutter speed is longer than (1 / OFF_VALUE)
Calculate value from exposure time
nnnnh = 10001h - (OFF_VALUE × ”Shutter Speed” )
Exp) Exposure time = 1/7.5 sec (for HV-F31CL)
10001h- (30×(1/7.5)) = FFFDh
Calculate exposure time from value
Shutter Speed[sec] = ( 10001h – nnnnh ) / OFF_VALUE
(6) AUTO EXPOSURE
Both gain and shutter speed are always adjusted automatically for proper video level.
Adjust the video level manually.
