Description

PHOTOGRAPHIC DEVICE PRODUCING FACE DATA AT BIOMETRICAL

STANDARDS

The present invention relates to a method of producing biometric photographs via a photographic imaging device and a method of generating biometric or other photographs in this photographing device, which are used for reading face biometrics safety data such as fingerprints and pupils; that are to be produced in full compliance with the ISO / IEC 19794-5 and ICAO / MRTD 9303-3 criteria and to form a global standard.

Biometry is a definition used for systems that are developed to identify an individual by identifying the measurable physical and behavioral characteristics of the individual. In summary; Biometrics refer to the measurable biological traces of a person.

In a known technique, in order to identify and verify an individual's identity, biometric data such as facial anatomy, fmgerprint, pupils (iris), DNA, vein traces are used. Face biometrics, one of these biometric data, are displayed via biometric photographs. Nowadays, biometric photographs are used for authentication purposes on documents such as passports, identity cards, visa, driver's license, etc. In the mentioned documents, biometric passport photographs should be used that fulfill criteria set by the ICAO ("International Civil Aviation Organization"), these being high quality, certain measurements and features, and fully detectable face biometrics. Biometric photographs are safety data which can be read by machines. In biometric photographs, data related to measurements of the face anatomy and physiology of a person are read as safety data. Biometric photographs are read by machines at safety points; - as is the case with a fingerprint - and ensure that the person's facial anatomy measurements are matched with personal identity information (verification). Since the anatomical and physiological measurements related to the face of a person are a determinative type of security data, it is very important to produce this data with a constant technique. This situation necessitates the production of biometric photographs according to certain global standards and criteria. Global criteria for biometric photographs are defined in the ISO / IEC 19794-5 and ICAO / MRTD 9303-3 standards. In order for a biometric photograph to be produced in accordance with the aforementioned standards, many technical and visual criteria have to be met. For example measurements and parameters such as; Background color (white), lighting of the photo stage, photo shooting technique, camera and equipment qualities, print quality, security rules that the person from whom the biometric photograph are to be compiled should be following, the face, head and eye position of the person, the face expression of the person, the amount of light arriving at the face of the person, distances related to person and the equipment are defined by the aforementioned standards. In biometric photographs, distances between the anthropometric reference points (anthropometric: a science dealing with the dimensions of the human body) are read out as safety data. The mentioned anthropometric references are determined by parameters such as; the distance between two eyes of a person, the distance between the eye and nose, length and width of jaw, distance between two ears, measurements of forehead and cheek, measurements of the skull, measurements of lip and ear. The face biometry of a person is determined in this way. The facial biometrics mentioned are used as security data by visualizing them with biometric photographs. For a biometric photograph to carry a security data quality, it is necessary that the standards mentioned above are fully fulfilled.

Biometric photographs are widely produced in the present technique where; after the photo shoot, the facial photo of the person is produced by using computer software and fitting the photograph into biometric templates. In this method, the photograph operator actually carries out the machine and stage-related settings. For taking biometric photographs, the photograph operator designs the equipment and studio structure at hand in accordance with the above- mentioned standards. Since known studio environments are not specifically designed to produce biometric photographs, these designs often fail to meet global standards. In the said method; the stage lighting, photographing technique, photographing device and equipment qualities, the amount of light arriving at a person's face, distances to person and equipment and even print quality differ in relation to the photo operator (human factor), studio and equipment structure. This reduces the consistency of security references of biometric photographs. In a method in which the human factor is such a determinant, it is not possible to attain standard consistency.

For example; illumination equipment that is not positioned at the right angle and at a distance and that does not always provide constant power, and ideal light color values cause the production of erroneous biometric photographs. Due to erroneous illumination in biometric photographs of the known technique, errors that affect the consistency of security references such as; Background shading, eyelid shadowing, difference of illumination between two ears of a person, nose shadow, red eye reflection, deterioration of hair, retina and skin color, chin shade etc. do occur.

For example; Sharpness errors due to human influence and / or print quality during photography influences biometric photographs adversely and affect measurable safety values.

For example; In all imaging systems including optical elements, the inability to position the system components correctly, as well as physical inadequacies, cause the images (perspective) to become distorted. The great human factor in the known method causes perspective distortions in biometric photographs. These distortions that arise when the perspective is curved convexly or concavely, lead to changes in the distance between the reference points that constitute the safety data of the biometric photograph. As a result, it is not possible to verify the identity of a person and establish a standard for security in biometric photographs.

In the known method, eye alignment of the biometric photographs is performed after the photograph was taken. This process is carried out by the photograph operator via various computer software. However, during the process of eye alignment using computer software after taking a photograph errors such as misalignment of the pixels and misalignment at the reference points may occur. This situation causes the deterioration of the biometric values and thus compromises the safety of the data.

In the known method, face position alignment of the biometric photographs is performed after the photograph was taken. This process is carried out by the photograph operator via various computer software. However, during the process of sizing and aligning with the help of computer software after taking a photograph, physiological reference points may deteriorate.

The ISO/IEC 19794-5 & ICAO/MRTD 9303-3 standards specify rules regarding the facial expressions of the person whose biometrical photo is to be taken. For example; no laughing, no eyebrow expression, natural eye opening, closed lips, no expressions in the chin or eyebrows are such rules related to facial expressions. In the present technique; The controls related to the face expression of the person whose biometric photograph is taken are carried out by the operator (photographer) during the photographing. However, these facial expressions can be evaluated differently by different persons (photographers). If the facial expression of the person whose biometric photograph is taken is not as specified in the rules, erroneous biometric references may occur. Leaving it to the only human initiative in the present technique makes it impossible to maintain a global standard for biometric photographs.

It is very difficult to produce biometric photographs in standard, stable and ideal image quality by means of the known method. To attain an ideal and standard image quality in photos, parameters such as illumination equipment, camera settings, graphic and image processor color profiles, recording and printing color profiles, light temperature, printing temperature, color space selection, etc. have to be stabilized and made compatible. However, in the known method, the technical knowledge of the photographers, the nature of the equipment, the infrastructure of the studios, etc. are different for every photographer. In this case, by using the known technique, it becomes impossible to produce biometric photographs with global standards. Print quality also plays an important role in the production of biometric photographs conforming to the standards. For biometric photographs to be a security data, these have to achieve the same reference values, always and everywhere, in a stable manner. In this context, parameters such as paper and other printing consumables' standard, printer scaling, color, contrast, sharpness and profile settings must be stabilized and standardized during the printing phase. However, each studio produces biometric photographs with its own printing equipment in the known technique. In this case, by using the known technique, it becomes impossible to produce biometric photographs with global standards.

In the present technique, biometric photographs are produced with a complex process which leads to security vulnerabilities. Following the photo shoot, efforts to fit the photograph into a biometric template by the hand lead to the loss of facial reality. This causes the incorrect identification of face biometry reference points. Matching incorrect biometric data with the identity of the person concerned causes security vulnerabilities. When the person concerned has another biometric photo taken in the future, the reference points do not seem to match those in the previous photograph. There is no solution to verify biometric photographs in the known technique. As an example, an official at the document registration office can not verify the authenticity of the biometric photograph presented to him, such as the authenticity of the shot, the time of the complete shooting, compliance with the standards and whether or not the photograph has been tampered with. All this verification can only be performed only via examination by people with high technical knowledge about the subject. However, it is not possible to pass each biometric photograph through the mentioned examination. A standard for production and control needs to be provided for biometric photographs with security data such as fmgerprints.

The present invention that is related to a method of producing biometric photographs via a photographic imaging device and a method of generating biometric or other photographs in this photographing device, which are used for reading face biometrics safety data such as fingerprints and pupils; that are to be produced in full compliance with the ISO / IEC 19794-5 and ICAO / MRTD 9303-3 criteria and to form a global standard, overcomes all of the aforementioned disadvantages and is characterized in that;

The photographing device mentioned has a specific (standard and ideal) design in terms of technical features (illumination, imaging, control and printing systems) and layouts, And therefore; establishes a standard in terms of features and layout of technical equipment (illumination, display, control and printing systems) used in photo production.

- The illumination, display, control and printing systems must be fully compliant with the criteria of ISO / IEC 19794-5 and ICAO / MRTD 9303-3 in terms of their properties and layouts within the device.

- A homogeneous light distribution on the stage and on the person's face is attained thanks to the illumination design inside the photographing device. In this way, errors related to illumination such as; Background shading, eyelid shadowing, a difference of illumination between two ears of a person, nose shadow, red eye reflection, deterioration of hair, retina and skin color, chin shade, etc. can be prevented.

- Simultaneous monitoring of the image captured by the imaging system by a computer software prior to taking a photo is provided. Clarity management, perspective verification, eye position verification, face position verification, face expression control, color verification, etc. operation are performed during this monitoring.

- All of the mentioned checks and verifications are performed pursuant to ISO / IEC 19794-5 and ICAO / MRTD 9303-3 criteria. - Thanks to the print management system located within the photographing device; Parameters such as paper and other print consumables' standard, printer scaling, color, contrast, sharpness and profile settings can be inspected according to ISO / IEC 19794-5 and ICAO / MRTD 9303-3 criteria. Therefore, lossless photograph prints can be attained.

- In the lower part of the biometric photographs produced by the photographing device, an imprint is present that contains the identification number of the person, the identity information of the person, the country code, the date and time of production of the photograph, the quality standard certificate, the fingerprint of the person and the QR code. Therefore, biometric photographs containing a verification system can be generated.

Standard, stable and ideal photographs can be produced thanks to the uniform design of the photographing device, the specification of equipment features and layouts, homogeneous and stable illumination system and control mechanisms conforming to ISO / IEC 19794-5 and ICAO / MRTD 9303-3 criteria.

The human factor has been reduced to a minimum level.

- It would make it possible to introduce a global biometric photography standard.

- The photographing device is suitable for use wherever biometric photography is used, such as; Photo studios, passport offices, government offices issuing license and identity cards, visa offices, consulates, military branches, schools, notaries, secure document registration offices, airports, etc.

- Three-dimensional biometric imaging can be performed on the photographing device.

- The exterior and interior design of the photographing device has an aesthetic appearance.

- It is easy, fast and practical to use.

The first objective of the photographing device for biometric imaging is to reduce the human factor to a minimum level and to obtain an idealized image with a global standard thanks to the uniform production method. The said photographing device contains equipment and control mechanisms that are selected, placed and arranged according to the criteria of ISO / IEC 19794-5 and ICAO / MRTD 9303-3.

The exterior design of the photographing device can be realized in different shapes. However, in the interior design, a structure is present that provides functionality in accordance with standards. A stage is present on one side of the photographing device. A stage is defined as the location where the person to be photographed during the photo shooting is located. A height adjustable swivel seat is present the middle of the stage. A backdrop with an ideal white color that accommodates illumination elements is present around the seat. The rear facade is furnished with illumination elements that are providing homogeneous lighting. Therefore a 100% white balance is achieved in the rear facade and absolutely no shadow is present. In addition, thanks to the rear facade that is encircling the stage (seat), a homogeneous lighting is created. As a result, no shadows and reflections appear on the face of the person as a result of illumination. Ideally, the person on the stage of the photographic equipment should be receiving 5500° Kelvin light temperature. In this way, the equal light intensity is captured at each pixel. Illumination elements are present on the top of the stage (ceiling). The amount of light arriving at the stage, the temperature and the angles are determined according to ISO / IEC 19794-5 and ICAO / MRTD 9303-3 criteria.

On the opposite side of the stage is the front panel where the display system is located. The aforementioned front panel has illumination elements on the surface that are facing the stage. A camera is present in the panel. The lens of said photographing device is pulled into the device through an opening in the panel and directed to the stage. An optional mirror is present on the face of the panel facing the stage. On the said mirror, a template is drawn for the eyes, face and the head position. The said template is conforming ISO / IEC 19794-5 and ICAO / MRTD 9303-3 criteria. Before the photo shooting, the eye and face position is set according to said template. In the said photographing device, the image of the person in the stage is simultaneously reflected on a screen on the back of the front panel. A template drawn for the eye and face position is present on the mentioned screen. The operator via the said screen controls the eye, face and head position of the person according to the template and confirms it. The said template ensures that the physiological face measurements of the person and the anthropometric reference points are obtained at the correct scale. In this way, it is possible to produce standard biometric photographs. If the face position of the person is not in the template, the operator alerts the person to re-position himself/herself according to the template. In the said device the eye alignment, verification of face position and measurement are carried out before the photographing. In this way, the photograph is not altered, and the original photograph is preserved.

The image of the person in the stage on the photographing device simultaneously transferred to a tablet, computer, etc. or a similar operating system. A control software is installed on the said operating system. The said control software is used to determine the eye, face and head position (according to the template) of the person, the face expression of the person, the accuracy of the light falling on the stage and the face of the person and other parameters in accordance with the criteria of ISO / IEC 19794-5 and ICAO / MRTD 9303-3. The said software ensures that biometric photographic criteria are followed by warning the operator and / or the person to be photographed in case of any error.

The printer system in the photographic equipment is also kept under control. In the print system; Parameters such as paper and other print consumables' standard, printer scaling, color, contrast, sharpness and profile settings are kept under control according to ISO / IEC 19794-5 and ICAO / MRTD 9303-3 criteria. In this way, the loss of biometric features of the photograph is prevented. In addition to the passport measurements in the printing system located in the photographic equipment, prints of photographic dimensions can be obtained in accordance with the visa standards of each country (over 200 countries).

In the lower part of the biometric photographs produced in the photographing device, a security imprint is present that contains the identification number of the person, the identity information of the person, the country code, the date and time of production of the photograph, the quality standard certificate, the fingerprint of the person whose photograph was taken and the QR code. In this way, the biometric photographs produced on the photographing device are easily verified. The fingerprint of a person can be obtained through a fingerprint reader inside the fingerprint device. Equipment features and distances are ideally set in the photographing device.

The printing system in the photographing device consists of a thermal printer with a resolution of 300x300 dots per inch, a capacity of 320 prints per hour, and 256 (8 bits) tone transitions for each color. In addition, printing papers that are conforming to ICAO standards are used in this printer. The imaging system included in the photographic equipment includes a camera with an image size of 18.7 megapixels, a live view frame rate of 30 fps (frames per second) and 9 AF (Auto focus; automatic focus) (f / 5.6 diagonal type in the center). The imaging system found in the camera unit has a minimum aperture of f 22, a maximum aperture of f/1.4, 58 mm. (millimeter) the diameter and a fixed focal length lens with a standard viewing angle of 46°. The operating system included in the photographic equipment includes a computer with a high graphics processor and a 1920x1080 resolution screen. The photographing device combines the 14 different components (control component) in the device and integrates them, it also provides daily, monthly annual reports of all the works. The 14 different components mentioned are; Global standards (ISO/IEC 19794-5 and ICAO/MRTD 9303-3), homogeneous lighting, sharpness adjustment, perspective adjustment, eye position verification, face position verification, face expression control, color control, lossless printing control, security imprint, mathematical virtual (virtual face) template, control of biometric reference points, person guidance board, secure file generation and storage.

Biometric photographs taken on a photographing device are obtained in accordance with ISO/IEC 19794-5 and ICAO/MRTD 9303-3, thanks to a single production method in which the human factor is minimized.

Homogeneous lighting is possible by positioning the light sources at the ideal angle and at the right distance. For example; The front lights reach the face of the person indirectly by spreading at an angle of 45°. The background lighting is creating a 100% white effect. Ceiling lighting supports general illumination while providing hair lightening. The lights, which are positioned at angles on both sides, complement the homogeneous illumination stage, preventing shadows from forming on the stage.

Additionally;

- The fixed diaphragm (light adjuster) keeps the light balance, contrast balance, depth of field and general sharpness constantly under control.

- The shutter (shutter speed) is fixed at 1/60 sec.

- Thanks to the ISO (sensitivity to light) value fixed at 200, the color and sharpness quality values are kept under control.

- Thanks to the color temperature fixed at 5500° Kelvin, each picture taken is obtained in daylight quality, more detailed and realistic.

- Thanks to the falling illumination stage spreading from 8 different regions, the facial images of people are obtained in clear and real manner.

Thanks to the LED illumination system that ensures the homogeneous spreading of the light inside the stage, hard light and shadow formation on people's faces is prevented.

- The background has a built-in background illumination unit with a light intensity of up to 50% of the side and front lights. This prevents the occurrence of color deviations, light reflections, and shadows caused by the effect of backlighting. In addition, the mirror around the camera reflects backlight back to the stage. - The white balance adjustment on the photographing device was fixed using an 18% gray card.

- Light penetration into the homogeneous light stage is blocked from the outside.

Thanks to the stage panel, which is designed in a semi-cylindrical shape, the lights from the outside are reflected inside, and the lights inside are not reflected on the outside. Thanks to the roof panel, reflections that may come from the top are also blocked.

- The lights that area placed on the panels surrounding the stage illuminate the faces of the people in the most ideal way. Thanks to the ceiling illumination that is located at the top of the seating area, a person's hair is illuminated with excellent light emission.

- Thanks to the two light units vertically positioned on the front panel, the retina of the eye are displayed more clearly and real.

- A key balance mechanism is present on the photographic equipment, that allows all lights that affect the stage to be changed at the same time when the operator needs to alter the light settings so that the standards are not exceeded.

High sharpness performance is achieved by using ISO "sensitivity" settings, which is set in the range of 100 - 200 for the sharpness setting. By using the diaphragm aperture determined at f/5.6 - f/1 , the sharpest result of the effective lens is achieved. The speed of the shutter (shutter speed) is determined and fixed according to the lens distance in the range of 1/60 - 1/125. Vibrations are prevented in this way. The multi-point sharpness feature is activated so that all points of the face are displayed in an equally clear view. Operator errors are prevented by the auto sharpening motor and camera sharpness feature. The image size is determined as 1024x769. The saved files are stored digitally at 300 dpi image resolution and are printed without displacing the pixels.

Thanks to the still camera positioned for the perspective setting, images are captured in high resolution and as close to reality as possible. The operator does not touch the camera during the shooting. A 50 mm (millimeter) lens is used, that allowing perspective correction in order to prevent concave and convex perspective distortions. The distance of the camera and lens to the person's face ( a distance of shooting), is determined to be 1400 mm (ideally). The camera and lens height should always be at eye level. The facial features of a person and the iris image of the eye are best obtained in this way. The balance between height difference is balanced by a height adjustable seat. Elevation of the camera from the ground is determined to be 1350 mm (ideally). As a version of the photographing device, the camera can be manufactured with adjustable height, mirror, and template.

At the time of the shooting, thanks to the stitching feature, it is not necessary to edit the face of a person with an external software in the photographs that are taken via the photographing device. In this way, all pixels within the photographs taken with the photographing device reflect the reality.

The live broadcast template displayed via the software is used, for eye position verification. The operator sees a snapshot on the operating system screen of the person whose biometric photograph is to be taken on the. On this screen, the template ensures that the face, eye and head alignment of the person are performed correctly. In the same way, a template is present in the photographing device that allows alignment on the mirror opposite of the person. If necessary, the operator alerts the person verbally and helps to complete the alignment. The image is taken as soon as the operator sees the correct alignment on the screen or the system detects an alignment. The person who is to be photographed biometrically sees his/her own image in the mirror located right in front of him/her when he/she is sitting on the stage of the photographing device. There are template strips on the mirror positioned at full eye distance indicating the horizon on both sides of the camera (lens). The person to be photographed aligns his/her eyes with this template. People with different heights can perform the alignment via the height adjustable seat. In addition, as a version, the alignment of the camera (of the lens) and the mirror (of the template) can be adjusted by raising and lowering these.

After the picture is taken and checked by the operator and the system, it is sent to the press and/or the register.

The above-mentioned templates and processes are also used for face position verification. A biometric face template is present in the opposite of the person to be photographed. In this way, the person is able to align his/her face, eye, and head. The said alignments are followed by the operator via the simultaneous image and template on display. The said template can be adjusted according to passport and visa standards.

Smile control, eyebrow expression control, eye openness control, lip expression control, chin expression control, etc. can be performed for facial expression control. The orientation plates inside the device prevent people who are to be photographed from doing the following; smiling, frowning, opening the eyes widely, closing the eyes partially, opening the lip or mouth too much, jaw expressions. The warning signs are located directly in front of the person. The said facial expression control is also performed by the operator through the simultaneous image. 8 bits and RGB (Red Green Blue) color space are used for each pixel for color control. In addition, the camera color profile, the live broadcast viewing screen color profile, the internal software color profile, the file color profile used during recording and the special color profile of the printing device are adjusted in the same way as a standard.

For lossless printing control, print tone, color, sharpness, contrast value, equal aspect ratio are controlled via the automatic controller. The printing system (printer) settings are set in a standard manner for each photographing device. In this way, a standard is achieved for biometric photographs. A thermal printer is used in the printing system. The print resolution is set to 300 dpi.

Biometric photographs produced on a photographing device do not undergo any alteration after shooting. In this way, biometric photographs can be produced without any distortion.

The said mathematical template consists of a central reference area of the skull, an alignment boundary of the crown of the head, an eye-gaze reference area, an eye horizon alignment tool, a right or left eye reference point, a jaw alignment boundary and a face center alignment line. Thanks to the mentioned template, the face reference points are perfectly defined. With the help of the biometric reference points control, the photographer is able to take photographs with the photographing device of the face, chin, eye grooves, nose, lip, morphological face height, physiognomic face height, upper face, middle face and lower face height values in a measurable manner. The image capture on the photographing device is supported by facial recognition algorithms and face capture technology. Security-certified biometric photography is ensured through photographic imprinting. In the lower or upper part of the biometric photographs produced by the photographing device, imprints are present that contain the identification number of the person, the identity information of the person, the country code, the date and time of production of the photograph, the quality standard certificate, and the QR code. The QR codes are used for photograph verification. Warnings are present in the person orientation panel for the person to be photographed. The said warnings, for example, are:

- Your shoulders should be facing the camera.

- Align your eye straight to the line that appears in the mirror.

- The frame of your glasses should not block your eyes from appearing.

- If you are wearing sunglasses, please take them off.

- Your hair should not cover your eyes.

- Do not smile and don not use any expression.

- Do not move and do not talk at the moment of the shooting.

- Your eyes should be open at the moment of the shooting.

- If you are wearing a hat, please remove it.

- If you have a headset, please remove it.

- If you are wearing a hat, please remove it.

- If you are wearing a headscarf, it should not obstruct the appearance of your facial lines.

The warnings listed above, and similar warnings, ensure that the person is prepared in accordance with ISO/IEC 19794-5 and ICAO/MRTD 9303-3.

Thanks to the above-mentioned technical features, distances, settings, controls, and warnings; Biometric photographs conforming to ISO/IEC 19794-5 and ICAO/MRTD 9303-3 standards can be produced by the photographing device. In addition, thanks to constant adjustments and stabilization, the camera removes human factors and other ambiguities, creating a global standard for biometric photographs.

The photographing device for biometric imaging (1) ensures that ideal biometric photographs (100) are produced all over the world in accordance with uniform and global standards. In this way, biometric photographs (100) can be used as completely reliable safety data.

The uniform structure of said photographing device (1) ensures that the specified equipment properties and locations are in accordance with the criteria of ISO/TEC 19794-5 and ICAO/MRTD 9303-3 and that stable biometric photographs (100) are obtained.

In the photographing device (1), the place where the person to be photographed (100) is, is called the stage (30). Panels are present around the stage (30). The rear side of the stage (30) is covered by the rear panel (6). The two sides of the stage (30) are covered with side panels (4). The top of the stage (30) is covered with a ceiling panel (2). The front transverses of the stage (30) are covered with transverse panels (5). There is only a slight gap between the transverse panels (5) at the front of the stage (30). Illumination systems (40) are laid on the surfaces of the said panels facing the stage (30). In this way, homogeneous illumination is provided in the stage (30), according to global standards. The back panel (6) has backlighting (44) elements on the surface facing the stage (30) forming a 100% white effect. The side panels (4) have lateral illumination (43) elements on the surfaces facing the stage (30) which provide homogeneous illumination in each region. The transverse panels (5) have elements of transverse illumination (42) on the faces facing the stage (30) that prevent reflection and shading. The ceiling panel (2) has elements of ceiling illumination (45) on the surface facing the stage (30) which illuminate the ceiling. As a version of the photographing device (1), there may also be a base illumination provided. The illumination system (40), which surrounds the stage (30), provides homogeneous lighting on the stage (30). In another version of the photographing device (1), the device has an upper front illumination (46) element which allows people with glasses to be photographed without reflections. A height adjustable swivel seat (31) is present the middle of the stage (31). A biometric photograph of the person on the stage (30) may be taken while sitting on the swiveling seat (31) or while standing.

Some clearance is present at the front of the panels surrounding the stage (30). Opposite this opening, a front panel (3) is present at a certain distance. The front illumination (41), the mirror (50), the imaging system (60) and the person orientation panels (70) are present on the surface of the front panel (3) that is facing the stage (30). The operating system (10), the operator table (11), the screen (12), the tablet (13) and the printing system (90) are located on the other surface of the front panel (3). The elements of the front illumination (41) are located on both sides of the surface of the front panel (3) that is facing the stage (30). As a version, the elements (strips) of the front illumination (41) are arranged at an angle of 45°. In this way, the light arriving at the person's face is sent in a softened manner, such that it does not create any shadow or reflection. During photographing of people with glasses, the front illuminators (41) are turned off, and the upper front illumination (46) is opened.

Between the strips of the front illumination (41), there is located at least one mirror (50). A hole defined as lens aperture (52) is present in the middle of the mirror (50). The imaging system (60) comprises of a lens (62) and a photographing device (61). The camera (61) is positioned inside the front panel (3). The lens (62) of the photographing device (61) exits through the lens aperture (52) in the mirror (50). The lens (62) passes through the mirror (50) via the lens aperture (52). The lens (62) protruding out of the lens aperture (52) is directed toward the stage (30). The Said lens (62) displays the person in stage (30). The ideal distance between the person on stage (30) and lens (62) has been determined as 1400 mm. The ideal height of said lens (62) from the ground has been determined as 1350 mm. However, the height of the lens (62) and therefore of the photographing device (61) and the height of the mirror (50) and therefore of the mirror template (51), can be changed via the height adjustment mechanism (300). The height adjustment mechanism (300) can be operated from the operator table (11).

On the mirror (50), a face template (20) is present which is drawn centered on the lens aperture (52) and thus the lens (62). The said face template (20) drawn on the surface of the mirror (50) is called mirror template (51). The mirror template (51) provides alignment for the face of the person on the stage (30), in relation to the lens (62) and confirming the measurements of a biometric photo (100).

The imaging system (60) reflects the image of the person in the stage (30) simultaneously to the tablet (13) and/or the screen (12). The operator follows the face alignment of the person with the template (20) located on the tablet (13) and on the screen (12). The template (20) visible on the tablet (13) and screen (12) is exactly the same as the mirror template (51).

The said template (20) comprises of at least one horizontal line, at least one vertical line forming a plus (+) shape by cutting said horizontal line perpendicularly and an ellipse or a circle centered on the said plus shape. Said horizontal line is called the eye horizon line (21). The Said vertical line is called the face center alignment line (22). The right eye reference point (23) or the left eye reference point is marked on one side of the eye horizon (21). The upper part of said ellipse is referred to as the skull center reference area (24). The point where the vertical line cuts the ellipse is called head crown alignment area (25). The point where the horizontal lines cut the ellipse is called eye-gaze reference area (26). The lower point where the vertical line cuts the ellipse is called jaw alignment limit (27).

When the person to be photographed (100) is placed on the stage (30), he/she sees himself/herself on the mirror (50) in front of him/her. The mirror template (51) on the surface of the mirror (50) provides the alignment of the person's face for the biometric photo (100). The said alignment is followed by the operator via the tablet (13) and or the template (20) on the screen (12). The operator following the alignment operation on the operator desk (11), conveys the necessary indications to the person on the stage (30) via the audible warning system (80). The person in the stage (30) aligns his or her eyes with the eye horizon (21). In addition, the right eye reference point (23) aligns the person's edge of the eye. The person in the stage (30) centers his/her face on the face center alignment line (22). The person on the stage (30) aligns the tip of the jaw to the jaw alignment limit (27). The person on the stage (30) places his/her face into the ellipse Via the skull center reference area (24), the head crown alignment area (25) and the eye groove reference area (26). In this way, the person on the stage (30) places his/her face on the biometric template at the moment of shooting. The person on the stage (30) adjusts the required alignment by means of the height adjustable and the rotary seat (31). When the person on the stage (30) fully positions his/her face according to the template (20), the biometric photograph (100) is taken by the operator or automatically. When the biometric photograph (100) is taken, the operator makes checks via software according to global standards. However, no subsequent alteration is made on the biometric photo (100) taken.

Biometric photographs (100) that conform to global standards are sent to the printing system (90) within the photographing device (1). Biometric photographs (100) sent to the printing system (90) are printed in accordance with global standards. The photographic imprint (110) and/or the QR code (120) and/or the fingerprint (130) are present on the photographing device (1). The photograph imprint (110) contains information such as the manufacturer's document number, the identification number of the person, the identification information of the person, the country code, the date and time of production of the photograph, and the quality standard document. The information is tracked via the QR code (120). The fingerprint (130) of a person can be received via the fingerprint reading device (200) prior to photographing, that is located in the photographing device (1).

On the stage (30) facing surface of the front panel (3) opposite the stage are the person orientation panels (70). The person orientation panels (70) allow the person on the stage (30) to position in accordance with the biometric photography (100) rules. If necessary, the person (30)on the stage can be warned by the operator to comply with said rules by means of an audible warning system.

An exemplary use of the photographing device (1) is as follows: A person who wishes to take a biometric photograph (100) enters the photographing device (1) and places himself/herself in the stage (30) surrounded by panels. The said person is sitting on the stage (30) on a seat (31). The face and the periphery of the person (30) on the stage are illuminated homogeneously by the all-around illumination system (40). The person in the stage (30) sees the front panel (3) when looking directly at the opening between the panels around him/her. A mirror (50), a lens (62), a front illumination (41) and person guide panels (70) are present on the surface of the front panel (3) that is facing the stage (30). The person whose biometric photograph (100) is to be shot, takes a position and adjusts the view according to the rules written on the person orientation panels (70). At the same time, the simultaneous image of the person on the stage (30) is transferred to the operator desk (11) via the imaging system (60) located on the front panel (3). The simultaneous image of the person is monitored on the operator desk (11) by means of the screen (12) and the tablet (13). In this way, the person who is adjusting his/her position and the view according to the rules written in the person orientation panels (70) can be followed by the operator. The operator warns the person on the stage (30) via the audible warning system (80), when necessary. As soon as the person adjusts his/her position and appearance to the rules, the face and eye alignment process start. The person on the stage (30) sees the mirror template (51) on the surface of the mirror (50) and the lens (62) in the center of the mirror template (51). The person who sees his /her face in the mirror (50) aligns his/her face with the mirror template (51). The said alignment process is again followed from the operator table (11). The operator controls the face and eye alignment of the person with the template (20) located on the screen (12) and the tablet (13). If necessary, the system alerts the person by means of an audible warning system (80). The person on the stage (30) performs face and eye alignment via the height, distance and angle adjustable seat (31). The operator and/or operating system (10) detects the alignment when the person on the stage (30) performs the face and eye alignment in an exact manner. Immediate control of illumination and other settings are carried out at the time of alignment detection. In this way, it is possible to produce standard biometric photographs on the photographing device (1).

Once the check of the obtained biometric photographs (100) has been performed, they are sent to the photo printing system (90). The photographic fingerprint (110), the QR code (120) and the fingerprint (130) are included in the printed biometric photographs (100). The front illuminators (41) can be fully closed or dimmed when photographs of people with glasses are being shot. In this process, reflections and shadows originating from the glasses are prevented by using the upper front illumination (46) instead of the front illumination (41).

In addition to passport measurements, prints can be obtained according to the visa sizes of all countries via the printing system. Additionally, dimensions can be adjusted in accordance with driver's licenses, identification cards, passports, etc.
