Portrait shooting device

Technical field

[0001] The present invention relates to a person photographing apparatus that controls lighting conditions of a subject.

Background art

[0002] As a human photographing device, a box-type ID photo photographing device for obtaining a face photo to be attached to a passport application form, a resume, and other examination application forms (for example, see Patent Document 1). ), Photo shooters that are placed in sightseeing spots that sell scenery, other scenery, and various event venues, and compose commemorative photos by synthesizing photographed figures and background images prepared in advance (for example, patents) Reference 2) is known.

[0003] These person photographing devices are usually stored in an unattended box or in a curtain-like partition, and a customer who enters the inside displays an operation display called a touch panel provided in these devices. According to the guidance sequentially displayed on the means, an instruction operation is performed to obtain a predetermined photograph.

[0004] The facial photograph created by the ID photo apparatus described above satisfies the predetermined requirements that meet the purpose of use, such as the fact that the person's characteristics are clear and the photograph size is appropriate. It is important whether or not the face photo created by the commemorative photo camera is good if it is a smile made with awareness in the background. Also, the face image taken is greatly exaggerated in the center because the distance between the camera and the subject is fixed at a distance where the distance between the camera and the subject cannot be secured due to a request to reduce the installation area of the box as much as possible. It is easy for the light to strike a 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 amount of light and the light distribution are conditions that allow a predetermined quality to be obtained beforehand through experiments. What you want is set.

[0006] However, the illumination light illuminates the upper body more widely than the one that irradiates only the face of a person. Therefore, the color and density of the face image to be photographed change due to the difference in the reflected light from various parts that hit the face, including the color and density of clothes worn by people. Turn into.

[0007] Therefore, even if an attempt is made 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 to a certain level.

[0008] In order to cope with such a situation, a full-time photographer individually sets various shooting conditions such as lighting conditions, and also guides a person who is a subject to create a good facial expression. In general, it is common to shoot without missing a camera with a dedicated camera.

[0009] However, providing a dedicated photographer as described above increases labor costs and may result in an increase in the cost of photographs.

[0010] In addition, recently, a method of obtaining a desired face image by performing image processing on a captured face image has become common, and these are image processing apparatuses for performing image processing. Technology is required, and the face image after image processing may become unnatural.
