    1. General The CV-M50 is a monochrome 1/2" CCD camera designed for automated imaging applications featuring high performance and unique functions within a uniform and compact housing. The high-speed shutter function and asynchronous random trigger function allow the camera to capture high quality images of fast moving objects.

    The edge pre-select mode operation will only work in non-interlaced and field accumulation mode. The CV-M50 starts the exposure (= accumulation of photoelectric charge) at the first HD pulse after the falling edge of the ext. trigger pulse. The exposure ends after the time set by the 3 shutter switches SW1-1 to SW1-3.

  • Page 9: Pulse Width Control Mode

    The pulse width control mode will only work in non-interlaced field accumulation mode. The exposure is controlled by the low period of the ext. trigger pulse. The CV-M50 starts the exposure at the first HD pulse after the falling edge of the ext. trigger pulse. The exposure ends at the first HD pulse after the rising edge of the ext.
