Abstract

A video timing test equipment for measuring light integration time of a camera. The video timing test equipment may comprise: a control unit and shutter timing test unit. The control unit may generate input timing signals adjustable by a user. The shutter timing test unit may comprise light emitting diodes (LEDs), infrared light emitting diodes (IR LEDs), and an output controller. The output controller may regulate the illumination of the LEDs and IR LEDs based on the input timing signals. The shutter timing test unit may also comprise a UTC time display, edge time display, and pulse width display. The UTC time display may depict a UTC time as to when light integration begins or ends. The edge time display may depict an offset time associated with the start or end of light integration. The pulse width display may depict the duration of light integration.
