Abstract
An extension photoflash light and a camera system using the same are provided. The extension photoflash light to be externally mounted on a mobile device with a photographing function comprises a HID lamp, a mounting mechanism, a light sensing circuit and a control circuit. The mounting mechanism is for mounting the extension photoflash light. The light sensing circuit is disposed on the mounting mechanism. The control circuit is coupled to the HID lamp and the light sensing circuit. When a camera program is executed, a specific block on a flat panel display of the mobile device emits a light signal. The control circuit controls the light sensing circuit to detect the light signal of the specific block, and decodes a decoding message according to luminance of the detected light signal, and controls the HID lamp to perform flashing at a specific timing according to the decoding message.
