Devices and methods are provided for redirecting or reflecting light from a camera's built-in flash unit. An exemplary device has a reflector member having a substantially planar surface, at least a portion of which is a reflective surface. A connecting member is provided that has a distal end portion and an opposing proximal end portion. The distal end portion can be attached to the reflector member and the proximal end portion can be configured for releasable mounting to a portion of the camera. The device can be operatively attached to the camera such that the reflector member is spaced from and opposes the flash and is configured to receive and reflect substantially all light produced from the flash.

A camera system includes a stroboscopic device (1) and camera (2). The camera (2) includes an information output unit which outputs, to the stroboscopic device (1), focal length information of a photographing lens, and size information indicating a magnification with respect to a reference size of an exposure surface of an image sensing element. The stroboscopic device (1) includes an irradiation angle changing unit (8) which changes the irradiation angle of strobe light, an information input unit (9) which receives the focal length information and size information from the camera (2), and a control unit (9) which sets the irradiation angle at a wide angle, if the product of the focal length and magnification is in the middle of a reference focal length range.

A stationary reflecting mirror (reflecting umbrella 2) is provided for reflecting light, emitted from a xenon discharge tube (3), to the side of an object to be photographed. An upper reflector plate (5) is provided above and in front of the stationary reflecting umbrella (2) and a lower reflector plate (6) is provided below and in front of the stationary reflecting umbrella (2). The upper and lower deflector plates (5, 6) are constructed so as to be pivoted in interlock with a change in the focal length of a photographic lens. With the upper and lower deflector plates (5, 6), part of light emitted from an opening (2A) is reflected and the direction of the reflected light that is emitted to the object is varied, and thereby the distribution angle of the light emitted to the object is varied. In this way, there is obtainable a flasher which is structurally simple and inexpensive without using high-performance lenses or an accurate moving mechanism.

A strobe device is provided, including a light source and a reflector which reflects part of the light emitted from the light source. The reflector is provided with a reflecting surface that is shaped to form virtual images of the light source behind the reflecting surface.
摘要:
A light source apparatus which comprises a flash discharge tube for illuminating a foreground subject, a switching element connected in series with the flash discharge tube, a light receiving circuit for photoelectrically converting light reflected by a foreground subject to produce a signal corresponding to the amount of light reflected from the received foreground subject and a decision circuit for producing an interruption signal for rendering the switching element non-conductive with partially as a function of the output signal of the light receiving circuit. A correction circuit for producing a correction signal in accordance with a preset film sensitivity is further provided. The decision circuit produces the interruption signal when the difference between the output signals of the correction circuit and light receiving circuit is reduced to zero.
