    5.9 Exposure Mode and Timing Chart The camera has three exposure modes. The overview of each mode and the timing are as follows. 5.9.1 Free Run Exposure Mode In free-run exposure mode, the camera generates its own internal control signal based on two programmable parameters, exposure time and readout time.

  • Page 38: External Trigger Exposure Mode (Trigger Edge)

    5.9.2 External Trigger Exposure Mode (Trigger Edge) In external trigger exposure mode (Trigger Edge), the exposure time is determined by setting the control register, and the line period is determined by the external trigger period. Each exposure starts with the rising edge of the trigger pulse. The range of programmable exposure time and the timing chart of the exposure and the readout are shown below.

  • Page 39: External Trigger Exposure Mode (Trigger Level)

    5.9.3 External Trigger Exposure Mode (Trigger Level) In external trigger exposure mode (Trigger Level), the exposure time is determined by the high trigger pulse time, and the line period is determined by the external trigger period. Each exposure starts with the rising edge of the trigger pulse. The range of programmable exposure time, the timing chart of the exposure and the readout are shown below.
