Meanwhile, as described above, in order to simultaneously express the real-time camera image and the photo object on the screen of the photo-generating apparatus, the photo-generating apparatus may connect the photo-object to the real- have. That is, the photo generating apparatus opens a file of the selected photo object according to a user's input or according to a predetermined command in the photo generating apparatus, and displays the corresponding file, that is, the selected photo object, And can be displayed on the screen.
Thereafter, the photo-generating device may perform photo-taking according to a user's input or a predetermined timer in the photo-generating device, and the photographed image may include only the image of the user, And may be a photograph including the photo object and the image of the user together.
Although not shown in FIG. 2, the photo-generating apparatus performs brightness control of the illumination and control of opening and closing of the transparent liquid crystal panel based on the measured illuminance, as will be described later, The amount of the light source to be applied can be adjusted. Alternatively or additionally, after taking the picture, the photo-generating device may estimate the light source in the picture obtained from the camera in the photographing section and correct it by software.
More specifically, in general, a photograph or an image obtained through a camera may cause a color mismatch with a photo object to be synthesized due to the influence of an ambient light source, resulting in a case in which a satisfactory image quality can not be provided.
Therefore, in order to reduce the influence of the ambient light source, the photo-generating apparatus controls the brightness of the illumination and the opening and closing of the transparent liquid crystal panel based on the illuminance measured by the illuminance sensor unit, It is also possible to adjust / control by hardware, and software adjustment / control for estimating and correcting the brightness of the light source for images taken separately or separately.
For this software control, for example, the light source brightness of the photograph or image is estimated through Retinex technology based on the color homeostasis which recognizes the unique color of the object by using the light energy reflected from the object to cancel the effect of the ambient light source And can compensate.
To this end, the photo generating apparatus converts the RGB image into a YCbCr space (Color Space), and calculates a brightness component of the light source by applying a Gaussian kernel of various sizes to the brightness channel. Also, in order to compensate for the brightness, the photo generating apparatus may divide the calculated brightness of the light source into brightness channels of a photograph or an image to compensate the brightness of the light source in the photograph or image.
In order to synthesize a photo or image that has undergone a preprocessing such as a photo object and a light source correction, the photo generator may adjust color and contrast in each photo or image, and convert the color and contrast thereof to perform synthesis.
a) Contrast control
In order for a picture or an image to be well represented, the gradation of each channel should be adjusted to be evenly distributed. However, in a general RGB color space, the color of a picture or an image changes due to correlation between channels. Therefore, in order to reduce the distortion of the color, the photo-generating apparatus separates brightness and chrominance through color space conversion and extracts and analyzes only brightness components.
After extracting only the brightness component, the photo-generating apparatus can analyze the distribution of each step of the gray-scale increase and the gray-scale increase by comparing the brightness histogram. Thus, the photo-generating device can reduce the over-enhancement defect that occurs when performing globally while keeping the shape of the histogram similar.
b) Saturation control
The color can be improved by adjusting the saturation in a photograph or an image having improved brightness in the photo generating apparatus. It is possible to perform correction by extracting only the saturation component according to the brightness using the color space conversion that can separate chromaticity and brightness components such as CIELAB and HSV as contrast adjustment and to perform correction by region, It may be estimated and corrected so as to reproduce the color with the preferred skin color. These will be described in detail later with reference to FIG. 5 to FIG.
FIG. 3 is a view illustrating a process in which a photo-generating apparatus according to an exemplary embodiment of the present invention performs light source control using an illuminance sensor and a transparent liquid crystal. FIG. Fig. 8 is an exemplary diagram for explaining a state in which the device is implemented in the form of a kiosk.
3, in order to control the light source by using the illuminance sensor and the transparent liquid crystal according to an embodiment of the present invention, the illuminance sensor unit in the photo- The illuminance can be measured.
That is, a predetermined space for taking a picture may be provided in the front portion of the photo-generating apparatus, and the predetermined space may have a size within a range in which the picture-generating apparatus can photograph. The user can perform photographing in a predetermined space for photographing, so that the illuminance sensor unit of the photographing apparatus can measure the illuminance of the predetermined space range.
In the present invention, the term " roughness " refers to a value measured by dividing the luminous flux projected into the predetermined spatial range by the area of the predetermined spatial range, and refers to the brightness of the predetermined spatial range. The unit of illumination can be lux or candela, where 1 lux is 1 meter away from a candle-power light source, and a plane perpendicular to the light It means brightness. If the distance from the light source is doubled, the illuminance can be 1/4 when the distance is three times, 1/9 when the distance is three times, and 1/16 when the distance is four times.
Meanwhile, the photo-generating device (or a separate control unit may be provided to perform the following control) may be configured such that the brightness of the light used in taking a picture of the photo-generating device, based on the illuminance measured by the illuminance sensor, Can be controlled.
More specifically, in the present invention, the brightness level of the illumination provided by the illumination unit may be classified into one of Low, Normal, and High. However, this is merely an example, but it is not limited to this, and it may be further subdivided or simply distinguished.
The lighting unit in the photo-generating apparatus may control the brightness of the lighting by setting a brightness level corresponding to the brightness level measured by the brightness level sensor unit during the brightness level of the lighting.
For example, when the illuminance measured by the illuminance sensor unit is low illuminance lower than a predetermined reference, the illuminating unit may control the brightness of the illuminance to be set to High. In this case, The brightness of the illumination becomes stronger, so that a larger amount of the light source can be introduced into the photo-generating apparatus when photographing. In addition, when the measured illuminance is a high illuminance higher than a predetermined reference, the illumination unit may control the brightness of the illumination to be set low, in which case the brightness of the illumination is relatively high So that only a small amount of the light source can be introduced into the photo-generating apparatus when taking a picture.
Meanwhile, the photo-generating apparatus (or a separate control unit may be provided to perform the following control) according to the present invention is installed on the front surface of the camera unit based on the illuminance measured by the illuminance sensor unit, It is possible to control the opening and closing of the transparent liquid crystal panel which controls the amount of the light source irradiated to the camera unit.
More specifically, the transparent liquid crystal panel may be attached to a front surface of a camera of the photo-generating device, and the transparent liquid crystal panel may be opened and closed. Also, according to whether the transparent liquid crystal panel is opened or closed, the transmittance of the light source irradiated to the camera unit can be controlled like a blind attached to a window to control the amount of sunlight flowing into the room. In the present invention, The control unit controls the opening and closing of the transparent liquid crystal panel based on the illuminance measured by the light source unit and ultimately controls the transmittance of the light source irradiated to the camera unit through the light source, You can adjust the amount of light source for the photo.
For example, when the illuminance measured by the illuminance sensor unit is low illuminance lower than a predetermined reference, the transparent liquid crystal panel can control to open the transparent liquid crystal panel. In this case, A larger amount of light source can be introduced into the photo-taking apparatus when taking a picture. The transparent liquid crystal panel may be controlled to close the transparent liquid crystal panel when the measured illuminance is a high illuminance higher than a predetermined reference. In this case, So that only a small amount of the light source can be introduced into the photo-generating apparatus when photographing.
Therefore, as shown in FIG. 4, the photo-generating apparatus according to an embodiment of the present invention may be configured to control the brightness of illumination according to the illuminating unit and / or the illuminance of the camera unit according to the transparent liquid- The camera of the photo-generating device can take a picture of the user reflecting the control result of the illuminating unit and the transparent liquid crystal panel to generate a photographing image for the user .
Referring again to FIG. 3, the photo-generating device that generates the photographed image of the user reflecting the control result of the illumination unit and the transparent liquid crystal panel may output the photographed image of the user as it is, It is possible to perform additional correction according to the sofrware process installed in the photo generating apparatus with respect to the photograph taken by the user.

In this case, the color space for obtaining the brightness component can be HSV (Hue, Saturation Value), HIS (Hue, Intensity, Saturation), CIELAB conversion and the like. As shown in FIG. 5, a Gaussian kernel ) Can be used to estimate the brightness component of the light source.
This is because, as described in Equation (1) below, the photo-synthesizing apparatus is capable of correcting the standard deviation of the Gaussian function
Referring to FIG. 6, in order to perform additional correction according to a process by software on a photograph taken with respect to the user, the photo-generating apparatus further brightens the brightness of the photographic light source extracted in accordance with the contents of FIG. 5 Or more darkly.
That is, the photo-generating device can compensate the brightness of the light source in the photograph taken with respect to the user. More specifically, the photo-generating device can calculate the brightness of the light source estimated in accordance with Equation (1) S ') to compensate the brightness of the light source by dividing each channel (I) of the RGB image.
Meanwhile, as described above, the photo-generating apparatus of the present invention can perform the synthesis or fusion of the photo image and the photo object with respect to the user. That is, an image obtained by synthesizing a photographed image and a photo object with respect to a user can be generated. At this time, the photo object and the photographed image for the user may be synthesized or fused, including improvement of color and contrast.

In addition, the photo-generating device may be combined with the photo object by adjusting a filter and a color in addition to the photo taken by the user.

To this end, the photo-generating apparatus adjusts the brightness of the illumination and the amount of the light source introduced into the camera by using the illuminance according to the method described above with reference to FIGS. 1 to 4, A light source may be estimated and corrected for a photographed image of a user, and a photographed image of the user who has undergone each or all of the processes may be synthesized through the image object and the image fusion technique. In this case, the image fusion technique can be interpreted as a concept including all techniques for combining or synthesizing images released up to now and combining or synthesizing all the images coming out in the future.
In addition, the image fusion may include image fusion through enhancement of color and contrast, and image fusion through correction of skin color and gray gradation, and the photo generating device may output a composite image generated through the image fusion, Alternatively, the image may be displayed on the screen of the photo generating apparatus.

Referring to FIG. 8, the photo-generating apparatus may perform histogram matching using a photo object, which is an object of the synthesis, and an image of the user, as described above.
Here, the histogram matching is a method in which the photo synthesizing device estimates the minimum value and the maximum value for each channel in each of the photographs and the photo objects for the user, and based on the smallest minimum value or the largest maximum value The histogram stretching technique is used to match the range of values between channels.
After performing the above-described histogram matching, the photo synthesizer may perform filtering and / or color correction. Further, the filtering and / or color correction means performing additional filtering and color correction processing on the photographed image for the user before the photo composite apparatus combines the photographed image with the photographed image for the user.
Further, the filtering and color correction may be performed in whole or in part on the photographed image for the user, wherein the entire image means the whole photographed image for the user, Such as skin color correction through the skin.
Meanwhile, the filtering uses a bilateral filter to reduce edge noise in a flat area while preserving edge portions of a photograph taken for the user, and reduce color boundaries and blurring The state means performing a role. The color correction may be performed by extracting only the saturation component using the color space conversion that can separate chrominance and brightness components such as CIELAB and HSV of the image and increasing it.
