*1 Saturation sets the gain value for Cb and Cr of the YCbCr signal. The gain is set value x 0.03125,
32 x 0.03125 = 1.00 [times] when the setting value is 32, and 76 x 0.03125 = 2.375 times when the setting
value is 76 (default).
*2 White balance is adjusted with our default optical system, and may not be fully adjusted depending on
the combination of lenses and filters. In that case, customization is also possible, so please contact us
individually. Also, when the auto white balance is turned on, the white balance is constantly adjusted in
response to changes in the screen, but it is not possible with normal software to fix the settings adjusted by
the auto white balance.
In this case, software customization is required, so please contact us individually.
*3 Exposure time is set to "2 to the power of the set value [seconds]" when set in the Windows standard
properties. For example, a setting of -7 (the default) gives an exposure time of 2^(-7) = 1/128 seconds
(approximately 7.81 milliseconds).
Otherwise, it will be set in units of approximately 100 microseconds.
For example, if the setting value is 80 (default value), the exposure time will be 80 * 100 = 8000[
μ
sec]
(about 8 milliseconds)
If the exposure time exceeds the default 1 frame time, the frame rate will be reduced.
*4 For monochrome type, brightness, contrast, vividness, sharpness, gamma, and white balance settings are
ignored. Only the settings of exposure time, gain, and low light compensation (external IO) are valid.
In addition, if you have any questions about settings or individual customization, please contact us.
