2 is a block diagram showing the configuration of a photographing apparatus according to the present invention.

Referring to FIG. 2, the photographing apparatus according to the present invention includes a camera 100 for acquiring image information of a user, a display 200 at which the image information is output, and one or more lighting devices 300 for illuminating the user and the background. And a controller 400 for comparing the image information with a preset standard standard, outputting a comparison result to the display, and controlling the camera position or angle and the irradiation angle or illuminance of the lighting apparatus to conform to the standard standard. do.

In the present invention, the standard standard refers to the international standard (ISO / IEC 19794-5) set by the International Civil Aviation Organization (ICAO) and the International Organization for Standardization (ISO / IEC). The standard specification is not limited thereto, and may be a standard set by an international convention or international organization for proof photographs.

The camera 100 is a digital camera. It takes a picture of the user and converts it into a digital signal.

The horizontal position is preferably set at the center of the face of the user of the camera 100, the vertical position is appropriate between the two eyes and the nose.

The camera 100 may be fixed and installed, but may be automatically fixed to the position by analyzing an image of a user acquired by the camera 100 by the operation of the controller 400. To this end, the camera 100 may be equipped with a driving device 110 operated by the control unit 400.

The camera 100 preferably maintains a distance within 0.7m to 1.0m from the user who is the photographed person. If it is too close or too far, the area occupied by the person in the whole image becomes too big or too small. In other words, the distance must be properly adjusted so that the face does not appear too large or too small in the picture. To this end, the controller 400 may control the zoom in or zoom out function of the camera to automatically adjust the size of the image of the subject in the entire image. In addition, the distance between the camera and the subject may be adjusted by controlling the driving device 110. In addition, the exposure value of the camera 100 may also be adjusted by the controller 100.

The control unit 400 acquires an image of the user in real time from the camera at any time before or after receiving a photographing command from the user, and adjusts the position and angle of the camera to meet the standard or the illumination. Perform preparations to adjust the angle and illuminance of the device. For example, the user may adjust his or her face position to the guide line, but after the controller 400 analyzes the image information, the user may operate the camera 100 so that the face area of the user is within the guide line. have.

The controller 400 separates and extracts a face region and a background region from a user's still image and detects an eye portion from the face region.

The controller 400 determines whether the still image conforms to a standard standard, wherein the standard standard includes at least one or more of a criterion for the clarity and background of an image, a criterion for a face, a criterion for an eye, and a criterion for an expression. Include.

The sharpness of the image means that there is shaking of the subject in the image. That is, the contour of the face or eye region of the person is extracted from the image and it is determined whether the contour is clear.

The criterion for the background is to check whether the background color is a single color or whether the complexity of the pattern of the background is larger or smaller than a predetermined reference value. There should be no people or other objects in the background. The complexity of the pattern is calculated using the variance of the color, and the brightness and the color are determined using the color average value of the background area.

The controller controls the illuminance of the lighting device that illuminates the background area when the background area does not meet the standard.

The reference regarding the face is an item for examining the position of the face, the size of the face, the direction of the face, and the shadow of the face.

The display screen on which the image of the subject is output has guide lines drawn according to the standard. If the picture was taken in a position suitable for the guidelines, the criteria for face would be satisfied to some extent.

However, for a more accurate determination, it is determined whether a face position is located at the center of the photograph in the extracted face region, and whether the horizontal and vertical size of the face is within a range of a preset reference value. The controller 400 analyzes whether or not too many shadows are generated by using the captured still image.

When determining the shadow of the face, the controller 400 determines that the number of pixels having a gray level of a predetermined reference value or less is greater than a preset value in the face area.

Each of the reference values described above are values that are set in advance to meet the standard by experiment.

The controller 400 zooms in or zooms out the camera or controls the driving device when one or more of the position of the face area, the size of the face area, and the direction of the face do not meet the standard standard. Adjust the position or angle of.

The eye criterion is an evaluation item regarding a distance between two pupils, redness of eyes, presence of glasses, whether eyes are closed or closed, eye direction, and the like.

Detects two pupils in the extracted eye image and checks whether the distance between the centers of the two eyes meets a predetermined reference range, and extracts the pupil color to check if the color is red. Examine whether the thickness of deviates from the standard range. In addition, it is checked whether a lens of a color not allowed by the standard is worn.

The standard for the expression is a test item for whether the mouth is open or whether the expression is natural.

The controller 400 extracts the mouth part from the still image and extracts a feature point along the lip outline or the contour of the lip to check whether the mouth is closed, or whether the ratio of white in the mouth part using the color of the tooth is greater than a predetermined reference value. Compare and check if the mouth is closed.

Whether or not the expression is natural is examined by checking whether the mouth is greatly laughing or frowning by comparing the characteristic points of various expressions stored in the database with the analyzed data.

The control unit 400 outputs a comparison result of the above-described inspection items on the display 200, but displays the inappropriate matters so that the user can know them.

For the inappropriate matters, the matters that can be corrected by adjusting the camera or the lighting device by the control unit 400 at the time of re-shooting are automatically corrected.

The controller 400 notifies the user of the comparison of the captured still image with the standard and if the comparison result is inappropriate, allows the user to retake the image. Even if the still image photographed satisfies the standard, if the user requests re-shooting, the re-shooting is performed within a limited number of times.

Finally, when the approval for the still image photographed by the user is made, the controller 400 stores the still image of the user, that is, an ID photo, in a memory or transmits it to a server of an external institution. Here, an external agency means an organization that issues public offices or other documents for certification.

The photographing apparatus according to the present invention may further include an illuminance sensor 500 for measuring illuminance in the photographing booth.
