Abstract

The present invention provides a flashing light device which can correctly confirm the irradiation area of flashing light device configured separate from camera, the camera and a flashing light system of camera thereof. The flashing light system of camera is composed of the camera (1), the flashing light devices (100A, 100B) which are separated from the camera (1) and can be used as the auxiliary light sources of photography. The flashing light system of camera comprises the following components: a light emitting part (11) which irradiates flash light to the object being shot; a camera shooting unit (15) which can do camera shooting to the image comprising the object being shot in the irradiation area of light emitting part (11); a transceiver circuit (201) which transmits the shot image that is shot by the camera shooting unit (15) to the camera (1); a built-in flashing light device (64) which is used for outputting a control signal from the side of camera (1) to the flashing light devices (100A, 100B); a communication circuit (304) which receives the shot image of irradiation area from the flashing light devices (100A, 100B); and a back LCD (67) of camera (1), which displays the irradiation area.

Description

technical field [0001] The present invention relates to a flashlight device, a camera and a camera flashlight system, in particular, to a flashlight device that can be used as an auxiliary lighting device for a camera such as an imaging device, and can be used in a position fixedly installed on the camera or separated from the camera, A camera that can operate in conjunction with the flash unit, and a camera flash system composed of these. Background technique [0002] This application claims priority to prior Japanese Patent Application No. 2008-25952 filed on February 6, 2008. This application is expressly incorporated herein by reference. The scope of the invention is not limited by any requirement of the specific embodiments described in this invention. [0003] When shooting with the auxiliary light of the strobe device, it is necessary to take the photo in consideration of the irradiation area of ​​the strobe device. Especially when the flash unit is placed at a pos...
