发明名称 Wireless camera flash trigger device
摘要 A flash accessory device readily adaptable to most compact digital camera models provides a hand grip with a mounting base for attachment to the bottom of a compact digital camera. The hand grip contains a multi-mode digital pre-flash detector circuit, a wireless transmitter and a battery power source. An articulating arm extends from the hand grip and is adjustably movable relative to the front of the camera in order to position a sensor on the end of the articulating arm directly in front of the camera's built-in flash. A cup member surrounding the sensor covers the built-in flash to block light emitted by the built-in flash. Light from the built-in flash is detected by the sensor which triggers transmission of a wireless signal from the transmitter to a receiver in a remote flash device to thereby activate illumination of the remote flash in synchronization with activation of the built-in camera flash.
