Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographing device for print photographs used for identification cards, student ID cards, passports and resumes, and an image forming method thereof.

[0002]

2. Description of the Related Art Photographing devices for ID photographs are very useful because they can obtain photographic prints of a predetermined size in a short time after inserting coins or bills. In such a photographing device for ID photo, for example, a user enters a box-shaped photographing box, sits on a chair in the photographing box, photographs the user as a subject by the operation of the user himself or an operator, A print photograph in which a plurality of images are recorded on a sheet-shaped recording medium can be obtained.

A plurality of illuminating devices are arranged in the box of the photographing device to photograph a subject in a bright photographing environment. In these illuminating devices, for example, the illumination for illuminating the subject brightly is above the front surface of the subject, the illumination for shadow removal of the subject's chin is below the front surface, and the illumination for shadow removal of the background is further provided. The illuminating device is arranged behind the person to be photographed to form a photographing environment in which the face image of the subject and the background are not shaded.

However, the above-described illumination device cannot illuminate the subject uniformly because the illumination light is directly applied to the subject, which causes local shining and shadows to impair the image quality. Was occurring. Therefore, a photography device equipped with an indirect lighting device in the photography box was examined, and a photography device that can obtain high-quality printed photos without local light or shadow without directly illuminating the subject has been found. Was issued.

[0005]

However, since the above-mentioned photographic device has the illuminating device arranged also on the left and right legs of the photographed person, the light from the illuminating device arranged especially on the entrance side is taken in the photographing box. The problem of leaking to the outside occurred, and the shooting device installed in a crowded place suddenly emitted light and surprised or uncomfortable a person who was around the shooting device.

[0006] Further, although the photographing device is used for photographing in an environment in which a curtain is arranged to block the outside light, it is newly found that the photographing device is susceptible to the outside light because it is photographed under indirect illumination. Was done. Especially in the photos taken in fine weather, some of the images were significantly affected by daylight and had uneven density, local shining or shadowing, and some of the photos taken at night were generally dark. Sometimes I could get a finished photo.

[0007] As described above, in a photographic device for photographing in an environment of indirect illumination, the influence of external light is easily reflected in the finish of the photograph, and it is difficult to obtain a print photograph having high image quality.

The present invention has been made in view of the above problems. That is, the first object of the present invention is to prevent the illumination light from the indirect illumination device from leaking to the outside of the image capturing device, thereby realizing an image capturing environment in which the illumination light is efficiently used without waste, thereby achieving a light amount balance. It is an object of the present invention to provide a photographing device capable of obtaining a beautiful finished quality face photograph without uniform density unevenness.

A second object of the present invention is to obtain a facial photograph having a beautiful finished quality with a uniform light quantity balance without being affected by the external environment such as external light regardless of the installation environment of the photographing apparatus. It is to provide a photographing device.

Further, a third object of the present invention is to eliminate the leakage of illumination light from the photographing device during photographing so as to prevent a passerby or the like who was around the photographing device from being surprised by light emission. Is to provide.

The printer unit 24 superimposes the recording medium and the image-receiving material and applies heat to transfer the coloring material of the recording layer of the recording medium to the image-receiving layer of the image-receiving material to form an image. By obtaining a print, the cost and size of the device can be reduced. Although the thermal sublimation recording method is used as the recording method of the printer, for example, a thermal melting transfer recording method, an induced thermal ablation transfer recording method, or the like can also be used. In the induced thermal ablation transfer recording method and the like, the color material layer itself or a layer formed below the color material layer is ablated by irradiation to provide a force necessary for the transfer. On the other hand, in the thermal fusion transfer recording method, the transition is caused by the thermal melting or thermal softening of the coloring material layer by irradiation. Further, the thermal sublimation method is a recording method in which ink particles fly and transfer by thermal sublimation.

When the printing is normally completed, the initialization is performed and the apparatus is put in a standby state for the next photographing (step S8).

As is clear from the results of Table 1, in Examples 1 to 5 which are the embodiments of the present invention, good results were obtained in both the daytime and nighttime illuminance difference and density difference. On the other hand, Comparative Examples 1-5
It was confirmed that both had large differences in both illuminance difference and density difference.

[0067]

According to the structure of the present invention, the illumination light from the indirect illumination device is prevented from leaking out of the photographing device, and the illumination light can be efficiently converted into indirect illumination light without waste. As a result of realizing the shooting environment, we have realized the provision of a shooting device that can obtain a facial photograph with a bright and beautiful finished quality without uneven density evenly balancing the light amount.

Further, in the image pickup apparatus according to the present invention, no matter how the installation environment is set, the image pickup environment is not affected by external light such as external light at all, and a beautiful finished quality with a uniform light quantity balance is obtained. It has realized the provision of a photographing device capable of obtaining a facial photograph having.

Further, the photographing apparatus of the present invention eliminates the leakage of illumination light from the photographing apparatus at the time of photographing, and provides a photographing apparatus which prevents a passerby or the like who was around the photographing apparatus from being surprised by light emission. did.
