    4 Camera Control The camera can be controlled through the serial communication. Two methods can be used to change the camera’s parameters. The first approach is to change parameters using CLISBeeCtrl(Camera control software). (See “8 CLISBeeCtrl”.) Or you can also change the parameters directly from your application by using binary read/write commands to set values in the camera register.

    4.8 Exposure Mode and Timing Chart The camera has three exposure modes. The overview of each mode and the timing are as follows. 4.8.1 Free Run Exposure Mode (Programming time setting) In free-run exposure mode, the camera generates its own internal control signal based on two programmable parameters, exposure time and readout time.

  • Page 36: External Trigger Exposure Mode (Trigger Edge)

    4.8.2 External Trigger Exposure Mode (Trigger Edge) In external trigger exposure mode , the exposure time is (Trigger Edge) determined by the setting for the line period parameter, each exposure starts with the rising edge and the line period is determined by the time from rising edge to rising edge of the internal control signal.

  • Page 37: External Trigger Exposure Mode (Trigger Level)

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

  • Page 41: Pixel Correction

    4.11 Pixel Correction Generally speaking, image sensors (CCD, CMOS and so on) have fixed pattern noise and photo response non-uniformity. Lens shadings and light sources also can cause non-uniformity. The camera is set to the optimal correction before shipping in order to provide images of high grade. The camera also has the function of user white correction to cope with lens shading and non-uniform illumination.
