The embodiment of the present invention shows the most preferable mode of the present invention, and the terminology of the present invention is not limited to this. FIG. 1 is a schematic configuration diagram of a subject photographing system. The subject photographing system 1 of this embodiment is used in an ID photo box 10 as shown in FIG. 2 or a portrait studio 20 as shown in FIG.

  The ID photo box 10 shown in FIG. 2 is installed in an isolated box-shaped casing 13 in the photographing room 11 and the machine room 12, and can form the ID photo box 10 that is widely used in general. A subject to be photographed enters the photographing room 11, sits down on a chair 14, pays a fee from a fee entry port 15, and takes a picture with a CCD camera as a photographing means 16. The photographed face photo image is developed and output as a photographic print to a discharge unit 17 provided on the side of the housing 13. A mirror 18 is provided on the side of the housing 13 and is used when the photographed person prepares a hairstyle, for example.

  The portrait studio 20 shown in FIG. 3 includes a chair 21, a background curtain 22, a lighting fixture 23, and a photographing camera 24. Thus, by setting each part in the studio, it functions as a portrait studio 20, and if a compact device is installed at a photo shop store, it functions as a simple studio.

  The subject photographing system 1 of this embodiment includes a photographing means 30, a photographing condition setting means 31, a subject attribute information acquisition means 32, a subject information input means 33, an illumination adjuster 34, an illumination condition adjusting means 35, an image processing means 36, It has an image output means 37 and a subject detection / startup switch SW1. A personal certification authority database 39 is connected to the photographing condition setting means 31 via the Internet 38.

  The subject photographing system 1 of this embodiment requires the image processing means 36 and the image output means 37, but generally known means (optical printing → development and digital image acquisition → digital image processing → image recording paper) Therefore, detailed description will not be given here.

  In this embodiment, by installing a plurality of illumination adjusters 34 around the subject 40 and adjusting them appropriately by the illumination condition adjusting means 35, various illumination conditions that are a kind of photographing conditions can be obtained.

  An important factor for lighting conditions is the softness of light. The softness of the light can be adjusted by adjusting the distribution characteristics of the incident direction of the light rays that illuminate the subject 40 to the subject 40. Specifically, for example, the size of the light emitting portion of the light source may be changed without changing the position of the light source. Hard light is obtained when the size is reduced, and soft light is obtained when the size is increased.

  As described above, the subject photographing system 1 includes the photographing unit 30 for photographing the subject 40 and acquiring the subject image, and the photographing condition setting unit 31 for setting the photographing condition of the subject 40, and is determined by the photographing condition setting unit 31.

Define the conditions. In this way, the shooting conditions of the subject 40 are determined based on the subject attribute information, and the subject can be shot under the shooting conditions suitable for the attribute of the subject 40. Therefore, a preferable photographic image that matches the characteristics of the individual subject 40 can be acquired. Easy to do.

  The imaging condition setting unit 31 has a function of adjusting the illumination condition of the subject 40, and functions as an illumination system that controls the plurality of illumination adjusters 34 by the illumination condition adjustment unit 35 to adjust the illumination condition of the subject 40. . By adjusting the illumination conditions of the subject 40, the effect of the present invention can be realized more preferably.

  The adjustment of the illumination condition performed by the imaging condition setting unit 31 is to adjust the distribution characteristic of the incident direction of the light beam that illuminates the subject 40 by controlling the plurality of illumination adjusters 34. By adjusting the distribution characteristic of the incident direction to the subject 40 as the illumination condition of the subject 40, the effect of the present invention can be realized more preferably.

  Prior to the acquisition of the subject image, the imaging unit 30 captures the same subject 40 under a predetermined imaging condition to acquire a pre-captured image, and the subject attribute information acquisition unit 32 extracts the subject attribute information from the pre-captured image. To do. That is, subject information is extracted from the pre-photographed image, and subject attribute information is acquired. At this time, subject information is acquired in advance, a precondition is set using the subject information, and a more preferable subject attribute information acquisition unit 32 can be used, thereby improving accuracy.

  The subject information includes gender, nationality, age, use of glasses, shooting purpose, and the like. This subject information can be obtained, for example, from various ID certificates for personal authentication and guarantee such as a driver's license and passport, as will be described later. Of course, it is obtained from the person to be photographed (subject himself) or ID card. When these are used, when using a face image for the update procedure, the old certificate can be inserted into the device and automatically read, making it a very convenient device. Of course, it is also possible to request key input from a subject (subject himself / herself) or an operator.

  The subject attribute information is the same as the subject information, such as gender, nationality, age, use of glasses, shooting purpose, etc., and facial features → glasses, nose bridge, lips, hair color, pupil color, skin color, There are eyebrow shape, hair color, skin condition (makeup, color tone, shine, wrinkle), carving depth, clothing, etc.

  Since the subject attribute information is acquired from the pre-photographed image of the subject 40 by such a method, even with a self-service system such as the ID photo box 10, the effects of the present invention can be realized with a simple procedure.

  The subject attribute information acquisition means 32 includes subject information input means 33 for setting or instructing subject information including subject attribute information by the operator of the subject photographing system 1 or the subject person himself. Since the shooting conditions can be set based on the subject attribute information obtained by the subject information input means 33, it is possible to reliably obtain a preferable photographic image that matches the characteristics of the subject 40.

  The subject attribute information acquisition unit 32 has a plurality of subject attribute information extraction methods. Further, the subject attribute information acquisition unit 32 is a subject whose information about the subject is the operator of the subject photographing system 1 or the subject person himself / herself. Subject information input means 33 for setting and instructing information is provided, and based on the subject information obtained from the subject information input means 33, it can be selected from a plurality of subject attribute information extraction methods described above. The method for acquiring a structure that is a kind of subject attribute from an image is not particularly limited. For example, the image edge information obtained by performing an edge detection process that detects an image edge appropriately selected based on subject information. On the other hand, it is possible to use a technique of performing a template matching process well known as an image processing technique and extracting a pattern related to subject attribute information. Alternatively, only the edge information representing a specific form such as a straight line, a circle, or an ellipse may be extracted by performing a Hough transform on the edge information, and the pattern matching process described above may be performed. Moreover, you may perform the acquisition of the three-dimensional information using the 3D sensor mentioned later, the skin surface characteristics (glossiness, mat property, the amount of fine wrinkles, etc.) using the surface remote sensor, etc.

  The subject information input means 33 further acquires personal authentication information of the subject, and acquires subject attribute information corresponding to the acquired personal authentication information. Since the subject attribute information can be acquired based on personal authentication information such as a driver's license, passport, and Basic Resident Register information card, the procedure is simplified. Further, if the subject photographing is used for the procedure for reissuing the certificate as described above, for example, these old certificates are inserted into the reading device provided in the subject information input means 33, and the Internet It is preferable that information exchange with the certification body in charge can be automatically performed through the information communication means 38 such as the above, and the re-issue procedure can be simplified. In addition, more detailed subject information and subject attribute information can be acquired through similar information exchange, and can be used for various processes of the present invention as described above.

  The system according to this embodiment includes image processing means 36 that performs image processing on a subject image to generate processed image information, and the image processing is performed based on the subject attribute information. For example, if the purpose of using the face image to be taken is a certificate (student ID card, employee ID card) of various organizations such as schools, companies, etc. It can be finished in dark and brown colors to produce a healthy and active image. In the case of an indoor company, it is possible to form an image with a clean and safe image by shifting the face color in the direction of fair white. In this way, face image processing that matches the impression of each organization can be performed. Similarly, it is possible to express an image according to the purpose and attribute of each person, and more preferable image processing corresponding to the subject attribute information can be performed. Therefore, it is possible to obtain a preferable photographic image suitable for the characteristics of each subject and the photographing purpose. Easy to do.

  Further, there is a subject attribute information acquisition unit 32 that acquires subject attribute information that is information related to the subject attribute, and an illumination that adjusts the illumination condition of the subject 40 based on the subject attribute information obtained from the subject attribute information acquisition unit 32 Since the condition adjustment means 35 is provided and the subject 40 can be illuminated under illumination conditions suitable for the attributes of the subject 40, when photographing the subject 40, it is possible to obtain a preferable photographic image that matches the characteristics of the individual subject 40. Easy to do.

  The adjustment of the illumination condition performed by the illumination condition adjusting unit 35 is to adjust the distribution characteristic of the incident direction of the light beam illuminating the subject 40 to the subject 40. The illumination condition of the subject 40 is the incident direction to the subject 40. By adjusting the distribution characteristics, the effects of the present invention can be realized more preferably.

  Next, an embodiment of the illumination adjuster 34 is shown in FIGS.

  The illumination controller 34 in the embodiment of FIG. 4 includes a diffusion box 34a, a diffusion plate 34b, a partial transmittance adjustment panel 34c, and a single light source 34d. A single light source 34d is disposed in the center of the diffusion box 34a, and the partial transmittance adjustment panel 34c and the single light source 34d are controlled by the illumination condition adjusting means 35 provided in the controller 34e.

[Wearing thick glasses]
<Preferred example of subject attribute information extraction method>
・ Performs pattern matching using spectacle templates to detect spectacle position ・ Acquires shadow information generated by spectacle edges ・ Acquires spectacle lens surface reflection information <Preferred illumination conditions>
・ Lighting that makes it difficult to see the shadow of the edge of the glasses. Cut light from below and irradiate soft light from the front to the top <Preferred shooting conditions>
-Inserting a polarizing filter in front of the camera based on the reflection information on the spectacle lens surface [wearing spectacles with thin edges]
<Preferred example of subject attribute information extraction method>
・ Performs pattern matching using spectacle templates to detect spectacle position ・ Acquires spectacle lens surface reflection information <preferred illumination conditions>
・ Illumination arrangement in which the reflection on the spectacle lens surface does not enter the camera direction ・ Flat surface light source irradiation that does not bother the reflection on the spectacle lens surface <Preferred shooting conditions>
-If necessary, a polarizing filter is inserted in front of the camera based on the reflection information on the spectacle lens surface.

The polarizing filter is a filter that limits the amount of transmitted light of polarized light by utilizing the fact that the light reflected on the surface obliquely hitting the substance interface is polarized. By preferably using this, reflection occurring on the surface of the spectacle lens can be suppressed. Since the direction of polarization varies depending on how the light beam is reflected, the direction in which the target reflected light is sufficiently cut may be selected by rotating the polarizing filter. Hereinafter, the polarizing filter is also used for the purpose of reducing skin shine, but the meaning and usage are the same. [When hair is thin]
<Preferred example of subject attribute information extraction method>
-Extraction of skin area and detection of light source reflection (shine) on head and forehead <preferred lighting conditions>
-Avoid the top light, or detect a reflection (shine) image of the head skin from the image, and search for an illumination condition that does not produce the shine.

  Specifically, for example, as in the flow shown in FIG. 10, images are taken a plurality of times with a certain period, and the lighting device shown in FIGS. 4 to 7 is partially turned on or off each time. Then, the occurrence or disappearance of the shining image may be detected and the disappearance condition may be used. Although this operation takes some time, as shown in the flow of FIG. 10, if the subject is automatically taken from the time when it is seated at a predetermined position, the subject himself or the operator sets the photographing contents and the like. It is more convenient to determine lighting conditions while Needless to say, this method may be used to determine the lighting conditions in which the reflected light from the lens surface of the glasses is difficult to be emitted.
