Description

  The present invention relates to a person photographing apparatus that controls lighting conditions of a subject.

  As a person photographing apparatus, a box-type ID photograph photographing apparatus for obtaining a face photograph attached to an application form for a passport, a resume, and other examination application forms (for example, see Patent Document 1), a prospect, Other commemorative photo photographic devices that are placed in sightseeing spots selling various scenery and various event venues, and compose a commemorative photo by combining a photographed person image with a background image prepared in advance (see, for example, Patent Document 2). It has been known.

  These person photographing devices are usually housed in an unattended box or in a curtain-like partition, and customers who enter the inside are sequentially displayed on an operation display means called a touch panel provided in these devices. According to the guidance, an instruction operation is performed to obtain a predetermined photograph.

  Whether the face photo created by the ID photo device described above satisfies certain requirements that meet the purpose of use, such as clearly showing the person's characteristics and the appropriate size of the photo Whether or not is important is important, and a facial photograph created by a commemorative photo-taking apparatus is often good if it is a smiling face made consciously in the background. In addition, due to the requirement to reduce the installation area of the box as much as possible, the center of the face image taken is greatly exaggerated because the distance between the camera and the subject is fixed at a sufficient distance, and the illumination light Tends to hit part of the face.

  In such an apparatus, the illumination conditions of the illumination light applied to the face of the person who is the subject at the time of shooting, that is, the light amount and the light distribution, are obtained in advance as conditions for obtaining a predetermined quality by experiment. Is set.

  However, the illumination light does not irradiate only the person's face, but widely irradiates the upper body. Therefore, the color and density of the face image to be photographed change due to the difference in the reflected light from various parts hitting the face, including the color and density of the clothes worn by the person.

  Therefore, even when trying to obtain a favorite face photograph as much as possible with the apparatus as described above, the quality of the face photograph may have to be compromised at a certain level.

  In order to cope with this situation, a dedicated photographer individually sets various shooting conditions including lighting conditions, and guides the person who is the subject to create a good facial expression. It is a common practice to shoot without missing a camera.

  However, providing a dedicated photographer as described above increases labor costs and may result in an increase in the cost of photographs.

In addition, recently, a method of obtaining a desired face image by performing image processing on a captured face image has become common, but these require an image processing apparatus and technology for performing image processing. In addition, the face image after image processing may become unnatural.

  The person who is the subject completes the processing such as charging, and presses the operation display means 16 of the person photographing apparatus or the photographing start button of the remote controller (not shown) (step S1), and is stored in the memory M of the control means C in advance. The illumination means 120, 130, 140 illuminate the subject under the standard setting conditions (step S2).

  The illuminated subject is captured as an image by the photographing camera CM in a preset short cycle (step S3), sent to the control means C, and displayed in real time on the operation display means 16 (step S4).

  The person who becomes the subject or the operator inputs the illumination conditions by the operation display means 16 or the remote controller (not shown), that is, inputs the instruction information for instructing the light quantity, light distribution, and color arrangement of the illumination light. (Step S5), the illumination light is changed (Step S6).

  The captured image is displayed on the operation display means 16 (steps S7 and S8), and the person who becomes the subject or the operator determines whether or not the displayed image is desired (step S9).

  If not desired (step S9: N), the illumination condition is input again, the illumination light is changed, and the captured image is displayed (steps S5 to S8).

  When a desired image is displayed by repeating steps S5 to 8 (step S9: Y), shooting is performed under the illumination conditions (step S10), and the captured image is output as a print (step S11). Get out of the routine.

  Note that the illumination condition input in step 5 may be performed by setting a plurality of types of illumination conditions in advance in the illumination condition setting table and selecting the illumination conditions from these illumination conditions.

  Note that the change of the illumination condition by the illumination means is not limited to the change in the light distribution of the illumination light as described above, and the illuminance of the subject is changed by raising and lowering the intensity of the illumination light uniformly. It goes without saying that the lighting conditions can be changed.

  The selected face image may be output not only to the printer PR but also to an appropriate storage medium such as a memory card.

  Further, the illumination means is not limited to the LED array, and any illumination means can be used as long as it can change the light quantity, light distribution, and color distribution of the illumination light and can provide directivity. For example, a combination of an EL (electroluminescence) display, a plasma display, a liquid crystal display and an array lens may be used.

  As described above, the human photographing apparatus according to the present invention can change the illumination area of the illumination light that illuminates the face for each partial area of the face, the amount of light, the light distribution, and the color scheme of the illumination light that illuminates the face. Therefore, it is possible to obtain a facial photograph with a desired complexion color and a facial photograph aimed at a predetermined effect.
