Description

{A hybrid camera for dental orthodentics used in both intraoral image capturing and face image capturing}

The present invention relates to a hybrid camera for orthodontics, and more particularly, to an orthodontic hybrid camera that can be used for intraoral imaging and facial imaging of a recipient required for orthodontic treatment.

In general, a dental hospital uses a photograph of a person's face and an intraoral photograph for orthodontic treatment.

1 shows an example of a photograph taken at a dental hospital for orthodontic treatment, and as exemplified in this, 4 external facial pictures and 5 intraoral pictures, a total of 9 pictures, are taken and used as a record before and after the procedure it is common to do

Here, the external facial picture is taken using the DSRL camera illustrated in FIG. 2-(a), and the intraoral picture is generally taken using the intraoral camera illustrated in FIG. 2-(b).

According to this shooting method, the DSRL camera used for external facial photography is heavy and must be manually operated every time it is taken. Because the camera focus and the patient's composition vary depending on the photographer, it is difficult to acquire a natural skin color tone when photographing the subject. There is a disadvantage that a unified image cannot be obtained.

In addition, since two different cameras are used, there is a disadvantage in that equipment purchases are expensive.

In addition, since two different cameras are used, it is difficult to match the tone of the two cameras because the tone of the photo of the DSRL camera and the tone of the photo of the camera exclusively for intraoral shooting are different. Thus, the tone of the image captured by the intraoral camera of FIG. 2-(b) is matched with the tone of the image captured by the camera of FIG. there is.

Alternatively, a pair of point light sources 191 and 192 may be provided on the opposite side of the photographing button 150 in the lower body 120 .

The light irradiated through these point light sources 191 and 192 may be, for example, laser light. Since the light irradiated through the point light sources 191 and 192 is irradiated to the face of the recipient, it is preferable to use light with as low an intensity as possible so that the recipient does not feel discomfort.

As shown in FIG. 6 , a pair of point light sources 191 and 192 are spaced apart from each other, and the first point light source 191 disposed above projects light downward and the second point light source 192 disposed below. ) projects the light upward.

Referring to FIG. 6 , when the object surface is at an appropriate distance, the lights irradiated onto the object surface from the first and second point light sources 191 and 192 overlap each other on the object surface to form a single point of light, whereas the object surface When the distance is closer or farther than the appropriate distance, the lights irradiated to the object surface from the first and second point light sources 191 and 192 do not overlap each other on the object surface and form different light points.

The distance between the first and second point light sources 191 and 192 and each irradiation angle are designed so that two lights are overlapped at an appropriate distance suitable for face imaging to form one light spot.

When taking a face, the camera user moves the camera 10 back and forth to adjust the distance between the camera and the subject surface while finding the position of the camera 10 where the lights irradiated from the first and second point light sources 191 and 192 overlap. and the corresponding position becomes a position corresponding to an appropriate distance for facial imaging. By performing the facial imaging at this position, it is possible to photograph the face in a state where the distance between the camera and the subject surface is appropriate.

In order to prevent the light irradiated from the first and second point light sources 191 and 192 from being shown in the photographed image, the first and second point light sources 191 and 192 are turned OFF at the same time as the photographing button 150 is pressed.
