    9.7.2 Edge Pre-select Trigger Mode (EPS) An external trigger pulse initiates the capture, and the exposure time (accumulation time) is the fixed shutter speed set by programmable exposure or Exposure Time Abs. The accumulation can be automatically set either LVAL synchronous or LVAL asynchronous in relation to FVAL and trigger timing.

    After the trigger pulse is input, a fast dump read out is performed. In the AT-140GE, this period is 16.04ms which is 352L. The exposure time is determined by the pre-set shutter speed. If no further trigger pulses are applied, the camera will continue in normal mode and the video signal is not output.

  • Page 48: Sequential Trigger Mode (Eps)

    9.7.5 Sequential Trigger Mode (EPS) This mode allows the user to define a preset sequence of up to 10 images, each with its own ROI, Shutter and Gain values. As each trigger input is received, the image data with the preset sequence is output as described below.

    Ethernet Interface. By the falling edge of the soft trigger 1, the image data is output. The AT-140GE has up to 4 frames to store, and the stored image data can be output at the consecutive timing of trigger 1.

  • Page 50: Smearless Mode

    AT-140GE 9.7.7 Smearless mode This function can be used to reduce the smear coming from bright areas of the image. This is effective for both EPS and PWC trigger modes. Before accumulation starts, the charge that is stored in the pixel is dumped by a high-speed transfer. This can reduce the smear that appears above the bright area but the smear below the area is unaffected.
