Abstract

(57) [Summary] [Problem] In conventional photography, patterns, colors, and shadows are mixed in the background of a subject, which is an obstacle in processing the background color. A photographing machine, a light source for irradiating a subject with flash light, and a background body (back screen) having a reflective layer on the background of the subject that retroreflects light from the light source only in the direction of the light source. Means are provided.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a photo photographing apparatus having a background (back screen) for creating a shadowless white background, which is suitable for processing the background color of various photographs and the like using a personal computer or the like.

[0002]

[Prior art]

 In recent years, for example, a system for easily creating an ID card with a face photograph using a personal computer has been developed. In these systems, a method of photographing a photograph of a face with a photographing device of a digital camera is known, but it has a problem with the background color of the subject (upper body).

[0003]

[Problems to be solved by the invention]

 However, in conventional photography, patterns, colors, and shadows are mixed in the background of the subject, which is an obstacle when processing the background color.

The present invention has been made in view of such a point, and it is possible to make the background of a person to be a subject a completely white without shadow, and to simplify the processing of processing the background color by the above-described system or the like. It is intended to provide a photographing device.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a photographing device according to the present invention includes a photographing device, a light source for irradiating a subject with flash light, and a reflection for reflecting light from the light source on the background of the subject only in the direction of the light source. And a background having a layer (back screen).

Further, a background body disposed behind a subject used for photography using a photographing machine having a flash light source has a reflective layer for retroreflecting light from the light source only in the direction of the light source. It is characterized by.

The background object according to the present invention reflects the light from the light source in the direction of the light source, so that not only the outline of the subject can be taken but also the background of the subject becomes completely white and no shadow, and the background of the subject can be obtained with image software. Can be easily and accurately performed.

In order to more reliably perform these processes, it is preferable to uniformly irradiate a flash or a flash emitted from a light source to a subject and a background body in a direction orthogonal to the subject.

[0009]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of the photographing device of the present invention, and FIG. 2 shows a cross-sectional view of one embodiment of the background body of the present invention.

As shown in FIG. 1, a photographing apparatus according to the present invention includes a photographing apparatus 1 such as a digital camera, a light source 3 such as a strobe for irradiating a subject 2 with a flash, and a subject. And a background body 4 having a reflective layer for retroreflecting light from the light source 3 only in the direction of the light source at a predetermined interval on the background of the device 2. It can be applied as a back screen in a used box-type photographing apparatus or a photographing apparatus such as Purikura (trade name).

In these devices, the light source 3 is adjusted so that the subject 2 and the background 4 are evenly irradiated in the orthogonal direction.

As shown in FIG. 2, the background body 4 has a reflection layer for retroreflecting light from a light source only in the direction of the light source. For example, a light-transmitting top resin layer, glass beads are enclosed. It is formed from a resin layer and a metal evaporation film that is a light reflection film provided almost at the focal point of the lens.The glass beads and the metal evaporation film reflect the received light at the focal position of the lens and direct it toward the light source. Any element that functions as a retroreflective element for retroreflecting light, etc., should have no or very little light scattering or reflection other than in the direction of the light source.

Next, the operation will be described. As shown in FIG. 1, the background 4 for photographing is attached to, for example, a wall surface or a support frame, and is provided so as to cover the entire photographing area. When taking a picture, the subject 2 is placed between the photographing device 1 and the background body 4 and a picture is taken.

When the flash from the light source 3 for photographing strikes the background body 4, the light is retroreflected by the background body 4 toward the light source, so that the background area of the subject 2 has a shadowless white color. , So-called white background.

The captured photographic image is directly converted into data, which is used for background processing by using the above-described another system, or a photographic apparatus incorporating an image processing apparatus or a printing machine. Then, a photograph having an arbitrary background color or background image can be created by performing image processing using the data.

[0016]

[Effect of the invention]

 According to the background in the photographing device according to the present invention, the background of the subject can be made shadowless white, so that a photograph having any background color or background image can be created.
