Exposure Mode - JAI SP-12000M-CXP4-XT User Manual

A = MAX (ROUNDUP ((2 × CXP_clocks) × (1 / CXP_clock_Hz) × (Sensor_Clock / Sensor_Reso) - 1),
ParameterX)
Line_Time = (A + 1) × (1 / Sensor_Clock) × Sensor_Reso
FOT = Line_Time × (ParameterY + 2)
Readout_Time = Line_Time × Sensor_Height / 2
Camera_FR = 1 / (FOT + Readout_Time)
B = ((2 × Height) + (Width × (Digital_bit / 8) × Height / 4)) / (Packet_Size / 4)
C = (26 + (((Packet_Size / 4) + 13) × B)) / Lane
FR_for_CXP_Packet = 1 / (C / ((CXP_clock_MHz) × (1 - 0.026) × 1000000)) + FOT
Frame_Rate = MIN (FR_for_CXP_Packet, Camera_FR)
* MAX (a, b): Larger of a and b
MIN (a, b): Smaller of a and b
ROUNDUP(a): Round up decimal values of a
Configurable ranges
Binning Off 1
Binning On 2
*1 Refer to the "Height" values in the "Configurable ranges" table above.
• Be careful of the maximum value during [Binning Horizontal].
• Only Monochrome is available during Binning On.
*2 Refer to the "Width" values in the "Configurable ranges" table above.
• Be careful of the maximum value during [Binning Vertical].
• Only Monochrome is available during Binning On.
Caution
• Although the maximum frame rate value is determined by the CXP bandwidth range, when ROI is
configured, the frame rate cannot exceed the sensor output's allowable frame rate value.

Exposure Mode

The following exposure modes are available on the camera.
Exposure Mode
Off
Timed
Trigger Width
™ The settings for exposure control and triggers are related to each other. Be sure to configure the settings
described in "Configuring Exposure and External Trigger Settings" (page 18).
In addition, exposure operations that support PIV (particle image velocimetry) can be specified in
[Trigger Option]. This function is enabled when [Exposure Mode] is set to [Timed].

128 to 2048
Exposure control is not performed (free-running operation).
Mode in which control is performed using exposure time. Acquire images using an
exposure time configured beforehand on an external trigger.
Mode in which control of the exposure time is performed using the pulse width of the
trigger input signal. The exposure time will be the same as the pulse width of the
trigger input signal. This allows long exposure.
