A well-known digital camera using a CCD or CMOS sensor as a photosensitizer, or a so-called disposable camera in which a simple lens unit is incorporated in a container containing a film, often has a built-in strobe device. These strobe devices include, for example, a glass flash discharge tube in which Xe gas is sealed, an aluminum reflecting umbrella in which the flash discharging tube is inserted, and a transparent or transparent material provided on the front surface of the reflecting umbrella. A semitransparent flat plate-shaped optical panel is provided, and the luminous flux directly emitted by the flash discharge tube and the luminous flux reflected by the reflector are radiated toward the subject through the optical panel.

面方向となるように構成されたものが一般的である。In these strobe devices, the luminous flux axis of the reflector is aligned with the front direction of the strobe device, and the flat optical panel is arranged so as to be substantially orthogonal to the luminous flux axis of the reflector, and the relative intensity of the luminous flux is set. Is generally configured so that the peak position thereof is substantially in the front direction of the strobe device.

いて極めて顕著となる。However, in the strobe device having the conventional structure, when a subject at a close range is photographed, the peak position of the relative intensity of the light flux is located farther than the subject. "Parallax" occurs. Such a problem becomes extremely remarkable in a mobile terminal such as a mobile phone having a built-in digital camera for the purpose of photographing a subject (for example, an owner) at a close range.

撮像装置の大型化を招来してしまう。As a countermeasure against this, it is not unthinkable to adopt a strobe device in which the light emitting portion is swingable so that the irradiation direction of the light flux can be arbitrarily changed within a predetermined range. In this case, however, the strobe device is used. Alternatively, the size of the image pickup apparatus equipped with it is increased.

かる構成を採用できない場合も出てくる。Alternatively, it is conceivable to arrange the reflector and the optical panel with respect to the front direction of the strobe device, but in this case, the exterior member (housing) of the strobe device is accommodated in correspondence with the inclination of the optical panel. It is necessary to change the shape, and in some cases, such a configuration cannot be adopted due to design and manufacturing cost reasons.

An object of the present invention is to provide a strobe device capable of performing the above.

A light flux emitted directly by the flash discharge tube, comprising: a flash discharge tube for emitting flash light; a reflector for inserting the flash discharge tube; and an optical panel arranged in front of the reflector. Also, in a strobe device that irradiates a light beam reflected by a reflecting umbrella toward an object through an optical panel, the reflecting umbrella is flashed so that the peak position of the relative intensity of the luminous flux is deflected in a direction different from the front direction of the strobe device. The optical panel is tilted in the direction around the axis of the optical panel, the back surface of the optical panel is an inclined surface that is substantially orthogonal to the luminous flux axis of the reflector, and the back surface is formed with a diffusing surface having a light diffusing action. A Fresnel lens is formed on the front surface of the optical disc with its center substantially aligned with the luminous flux axis of the reflector.

される。At this time, since the light flux is emitted in a direction inclined with respect to the front direction of the strobe device, by directing this toward the optical axis side of the image pickup device, it becomes a region at a relatively close range of the image pickup device. The peak position of the relative intensity of the light flux coincides with each other, and the necessary amount of light for the subject in this area is secured.

ができる。As described above, in the strobe device according to the present invention, the peak position of the relative intensity of the light beam can be positioned in the relatively short focal length region of the image pickup optical axis by inclining the irradiation direction of the light beam. Therefore, it is possible to prevent the parallax by eliminating the shortage of the light amount of the subject at the shortest distance.

も可能となる。Moreover, since the front surface of the optical panel is a surface which is substantially orthogonal to the front direction of the strobe device, the front surface of the strobe device can be made to have a flat appearance shape, and especially the appearance shape must be changed. Instead, the exterior member used in the conventional strobe device can be used as it is.

成することを特徴とするストロボ装置。1. A flash discharge tube that emits flash light, a reflector that inserts the flash discharge tube, and an optical panel that is arranged in front of the reflector, and the luminous flux and reflection directly emitted by the flash discharge tube. In a strobe device that irradiates a light beam reflected by an umbrella toward an object through an optical panel, the reflector is used as an axis of a flash discharge tube so that the peak position of the relative intensity of the light beam is deflected in a direction different from the front direction of the strobe device. The rear surface of the optical panel is tilted in the direction of rotation, the rear surface of the optical panel is an inclined surface substantially orthogonal to the luminous flux axis of the reflector, and a diffusion surface having a light diffusion action is formed on the rear surface, while the front surface of the optical panel is formed. The strobe device is characterized in that a Fresnel lens is formed with its center substantially aligned with the luminous flux axis of the reflector.
