6.3. Camera’s functions
6.3.1. Shutter Speed
The exposure time (electronic shutter speed) of the camera can be set in 100μsec unit
(1 line time resolution).
The exposure time can be calculated by the following formula:
Exposure time = the setting value of the shutter speed * 100μsec (Setting Range: 1～30000)
The calculation formula for the 1 line time is different for every single mode.
When outputting all pixels (2048 x 1536)
1 line time = (2048 + 208) * 0.375 * 1/74.25 [μsec] = 846 * 1/74.25 [μsec] = 11.394[μsec]
Exposure time(min) = 1 * 100[μsec] = 100[μsec],
[100 / 11.394] * 11.394 = 91.152[μsec]
Exposure time(max) = 30000 * 100[μs] = 3000000[μsec],
[3000000 / 11.394] * 11.394 [μsec] ≒3.0[sec]
When setting to ROI mode
1 line time = (Effective horizontal pixels + 208) * 0.375 * 1/74.25 [μsec]
※When ROI mode is performed, the settings of exposure time can be inherited, however, it may be
truncated according to sensor’s upper/ lower limit values.
For instance, when changing from a full resolution state where exposure time is set to 3 seconds, to a
ROI mode of 640*480 resolutions,
1 line time = (640+208) * 0.375 * 1/74.25 = 4.283[μsec],
then, the upper limit of the exposure time = 4.283[μsec] * 32767[lines]=140[millisecond],
Thus, the exposure time is set to be 140 milliseconds.
※If the frame rate does not rise, there is a possibility that the exposure time is longer than 1 frame time,
despite to ROI mode.
In such a case, please set the exposure time to <1 frame time.

6.3.2. Analog + Digital Gain
Analog gain and digital gain are installed in the sensor of this camera.
For the set value [0~480] of the software, the floating range of the gain magnification
changes from 0.0 dB to 48.0 dB.
Formula for calculating the gain magnification:
Gain [dB] = Gain’s set value / 10.0 [dB]
When the setting value is over 240, the digital gain data becomes valid.
The relationship between gain set value and magnification [dB] is shown as below:
6.3.3. Black level adjustment
As for this camera, offset of the Black level is added to the data where the digital gain is applied.
The initial set value of the black level is 80 when outputting 12bits.
Therefore, the luminosity value (or [brightness value]?) in a light shaded state will be around 5 when
outputting 8 bits (or 24 bits color)
※If you wish to change this value, please contact our sales department.
