Description

  The present invention relates to a person photographing apparatus having illumination means using a strobe.

  When photographing a person, it is generally well known that illumination light for illuminating a person is important together with a camera as a photographing means.

  The main reason is that the facial expression changes greatly due to the illumination light applied to the human face. Further, in the case of a person wearing glasses, reflection of illumination light by the lens surface of the glasses becomes a problem.

  As a light source for illumination, a strobe that emits light by applying a high voltage to a xenon tube is often used as illumination means. The reason is that, although the strobe is small in size, it has a sufficient amount of light emission for photographing and there are few problems of heat generation.

  In general, a strobe is often provided with directivity by a reflecting mirror, a lens, or the like so that the amount of light directed toward the subject is as large as possible (see, for example, Patent Document 1).

  Therefore, a shadow directly appears on the subject directly illuminated by the strobe light, and reflected light from the reflecting surface of the subject also appears partially strong.

  A person image photographed using illumination light having the characteristics described above is generally difficult to accept with good feeling, and may not meet specifications depending on the photographing purpose.

  Therefore, technical means for providing auxiliary light other than strobe light or irradiating the subject with indirect light obtained by reflecting the strobe light with an appropriate reflecting surface instead of direct light is proposed (for example, see Patent Document 2). ) Has been put to practical use.

However, the increase of various light sources due to such technical means complicates the control of illumination light and tends to increase the size and cost of the apparatus.

In this figure, the description of the control means, printer, power source, and the like arranged in the main body 1 is omitted because they are not directly related to the description of the present embodiment.

  By the mirror M, the person P standing in front can confirm the position and expression of his / her face reflected on the mirror M.

  Further, the region H located in front of the lens of the photographing unit 20 is a half mirror, and the photographing unit 20 can photograph the person P through the mirror M.

  The operation display means 10 is a known means for receiving an image display and an input corresponding to the displayed image on a touch panel.

  The light source unit 30 includes a xenon tube as a light source and light guide means, and light emitted from the light source is divided into four directions, up, down, left, and right by the light guide means.

  The upper and lower surfaces y1 and y2 and the left and right surfaces x2 and x1 of the main body 1 are provided with openings, and the light divided into four directions by the light guide means corresponds to the corresponding reflecting means M1, M2, The light is emitted from the plurality of openings toward M3 and M4.

  The light emitted from the opening is reflected by the reflecting means M1 to M4 having reflecting surfaces that reflect the light, and travels toward the person P who is the subject as indicated by the dotted arrows z1 to z4 in the figure.

  Thus, the person P is illuminated by the indirect light reflected by the reflecting means M1 to M4, not the direct light of the light source.

  In addition, dividing illumination light in four directions, up, down, left, and right in this way is a useful technical means that can obtain an illumination condition that produces an optimal shadow by adjusting the illumination light from each direction.

  The light source unit 30 including the light guide unit is disposed at an appropriate position behind the photographing unit 20 so that light emitted in the vertical and horizontal directions from the light source does not directly enter the lens of the photographing unit 20. It is desirable.

  The photographing means 20 is provided with a light shielding member including a lens hood for preventing the emitted light from being reflected inside the apparatus and entering the lens.

  3A and 3B are conceptual diagrams of the light source unit 30. FIG. 3B is a front view, FIG. 3A is a top view, FIG. 3C is a bottom view, and FIG.

  The light source unit 30 includes a light source 31 that is a xenon tube and light guide means 32 having a plurality of reflecting surfaces.

  The xenon tube of the light source 31 discharges light when a high voltage is applied and emits light, and is widely used as a light source lamp of a strobe.

  The light guide means 32 includes a pentagonal cylindrical portion having both ends opened to accommodate the light source 31, and reflecting portions provided at both ends. The inner surface of the light guide means 32 is a reflection surface that reflects light.

  As shown in FIG. 3A, the upper plate 321 of the light guide means 32 is provided with an opening 322, and the light emitted from the light source 31 travels upward from the opening 322 and is reflected by the reflecting means M1. It is reflected and illuminates the face of the person who is the subject from above.

  Further, as shown in FIG. 3C, openings 332 are provided at both ends of the lower plate 331 of the light guide means 32, and the light emitted from the light source 31 travels downward from the openings 332. Then, it is reflected by the reflecting means M2, and the face of the person who is the subject is irradiated from below.

  Further, as shown in FIGS. 3B and 3D, openings 341 are provided on both sides of the light guide means 32, and light emitted from the light source 31 is emitted from the openings 341 on both sides. Then, the light is reflected by the reflecting means M3 and 4, and the face of the person who is the subject is irradiated from both sides.

  A reflection surface 342 is provided above both side portions of the light guide means 32, and a part of the light emitted from the opening 341 is reflected by the reflection surface 342 toward the reflection means M2 below. The face of the person who is the subject is irradiated from below.

  4, 5 and 6 are diagrams for explaining illumination light for irradiating a subject.

  It should be noted that the light path indicated by the dotted arrow in the figure actually indicates the light path at a representative position of the spread light having a certain directivity.

  FIG. 4 shows a state in which light traveling upward illuminates the subject. Similarly, FIG. 5 shows a state of illumination by light traveling downward, and FIG. 6 shows a state of illumination by light traveling in the lateral direction. It shows a state.

  As described above, the illuminating unit in the person photographing device D according to the embodiment of the present invention reflects the light source unit 30 including the light source 31 and the light guide 32 and the light emitted from the light source unit toward the person who is the subject. And a plurality of reflecting means M1 to M4.

  That is, by such illumination means, the light guide means 32 prevents the light from the light source 31 from directly irradiating the person, and the person is irradiated with indirect light having a certain spread from multiple directions.

  Further, one end of each of the reflecting means M1, 3, 4 is fixed to the main body 1 so as to be rotatable. By changing the fixing angle of the reflecting means M1, 3, 4, the direction of the illumination light toward the subject is changed. Since it can be changed, more preferable illumination conditions can be set.

  In the present embodiment, the reflecting means M2 is fixed. However, like the reflecting means M1, 3, and 4, one end is rotatably held so that the reflecting direction of each reflecting means is variable. It may be.

  Therefore, the person photographing device D according to the embodiment of the present invention is a small device that does not directly apply light emitted from one light source to the subject from the front, but on a reflecting surface having a large area from four directions, top, bottom, left, and right. Since the subject is illuminated with reflected illumination light, and the face shadow can be changed by adjusting the angle of the reflecting surface, the face shadow can be changed slightly, The reflection can be reduced and a more preferable face photograph can be obtained.
