Command Description
20H:
EXPOS [7:0]
21H:
EPXOS [15:8]
22H:
EXPOS [23:16]
[Exposure time of electronic shutter] Default data: EXPOS[23..0] = 1,000, Data range: 0 to 16,777,215
Sets the preset shutter speed (exposure time) for electronic shutter.
Exposure time (shutter speed) = 1 * EXPOS[23..0] (µseconds)
*
When setting as “0”, exposure time is full exposure (longest exposure time at maximum frame rata).
28H:
TRG_DELAY_NUM
[7:0]
[Delay time for trigger signal] Default data: TRG_DELAY_NUM[7..0] = 0, Data range: 0 to 255
Sets the delay time from trigger signal input to start exposure.
Delay time = 2 * TRG_DELAY_NUM[7..0] (µseconds)
29H:
TMP_SENSOR
[7..0]
[Camera inside temperature] Default: TMP_SENSOR[7..0] = Variable
Obtains the temperature of inside of camera (temperature sensor on FPGA board)
Temperature [deg. C]

31H:
DIGITAL_GAIN
[7..0]
[Digital gain] Default: DIGITAL_GAIN[7..0] = 0, Data range: 0 to 255
Image output level = (Image input level - CLAMP[7..0]) x (1 + DIGIAL_GAIN[7..0] / 64) + CLAMP[7..0]
CLAMP[7..0]: Clamp level
38H:
CLAMP [7:0]
[Clamp level] Default data: CLAMP[7..0] = 8, Data range: 0 to 63
Sets the 8bits clamp level of black signal.
40H:
TMP_SENSOR _
PCB1 [7..0]
[Camera inside temperature] Default: TMP_SENSOR_PCB1[7..0] = Variable
Obtains the temperature of inside of camera (temperature sensor on CMOS image sensor board)
