1 is a block diagram schematically showing a digital photographing apparatus according to an embodiment of the present invention, and FIG. 2 is a block diagram schematically showing a part of the digital photographing apparatus of FIG. 1.

The overall operation of the digital photographing apparatus is integrated by the CPU 100. In addition, the digital photographing apparatus includes an operation unit 200 including a key for generating an electrical signal from a user. The electrical signal from the operation unit 200 is transmitted to the CPU 100 so that the CPU 100 can control the digital photographing apparatus according to the electrical signal.

In the preview mode, the CPU 100 controls the lens driver 11, the aperture driver 21, and the imaging device controller 31, and accordingly, the position of the lens 10, the degree of opening of the aperture 20, and the like. The sensitivity of the imaging device 30 and the like are controlled. This may be done as an electrical signal from the user is applied to the CPU 100 or may be automatically made by the CPU 100. Of course, not all of the position of the lens 10, the opening degree of the aperture 20, the sensitivity of the image pickup device 30, etc., but may control only a part of the various modifications are possible, of course.

The imaging device 30 generates data from the input light, and the analog / digital converter 40 converts the analog data output from the imaging device 30 into digital data. Of course, the analog / digital converter 40 may not be necessary depending on the characteristics of the imaging device 30.

Data from the image pickup device 30 may be input to the digital signal processing unit 50 via the memory 60, or may be input to the digital signal processing unit 50 without passing through the memory 60. It may also be input to 100. The memory 60 is a concept including a ROM or a RAM. The digital signal processor 50 may perform digital signal processing such as gamma correction and white balance adjustment, if necessary. In addition, as will be described later, the digital signal processing unit 50 includes a face recognition unit 51 and a face overlap determination unit 53, which allow the user to easily and quickly determine whether faces are overlapped when capturing a plurality of people simultaneously.

That is, in some cases, the lens driver 11, the aperture driver 21, or the like may not exist. The digital photographing apparatus according to the present embodiment may include a face recognition unit 51 and a face overlap determination unit 53. Hereinafter, the functions of the face recognition unit 51 and the face overlap determination unit 53 will be described with reference to FIGS. 3 to 7.

FIG. 3 is a conceptual diagram schematically showing one preview image PI1 for explaining the operation of the digital photographing apparatus of FIG. 1, and FIG. 4 is another preview image PI2 for explaining the operation of the digital photographing apparatus of FIG. 1. It is a conceptual diagram which shows schematically.

The digital photographing apparatus according to the present embodiment displays a preview image, which is called a real-time video, in the preview mode on the display unit 80 to allow a user to select a shooting composition, and to store still image data according to a signal from the user. Save to media. That is, the preview image may be referred to as a frame image of a real time video displayed on the display unit 80 in the preview mode.

The face recognition unit 51 may recognize faces in an image from the data generated by the image pickup device 30, and the face overlap determination unit 53 may overlap the faces among the faces recognized by the face recognition unit 51. It can be determined whether there is. That is, in the preview mode, the face recognizing unit 51 may recognize faces in the preview image from the preview image data generated by the image pickup device 30, and the face overlap determination unit 53 may recognize the faces. It may be determined whether there is an overlapping face among the recognized faces.

The digital photographing apparatus according to the present embodiment including the face recognizing unit 51 and the face superimposition determining unit 53 includes the image pickup device 30 until there is a signal from the user to acquire still image data in the preview mode. The face recognition unit 51 recognizes faces included in the preview image from the generated preview image data and whether there is an overlapping face among the faces recognized by the face recognition unit 51. If it is judged and nested, it is notified to the user. This allows the user to easily determine whether the face is hidden within a short time when the composition is determined while viewing the preview image in the preview mode to obtain still image data including the faces of a plurality of people. You can do that.

That is, when the user is looking at the preview image in the preview mode to capture the plurality of people, the display unit 80 displays the preview image PI1 in which the faces of the plurality of people to be photographed do not overlap as shown in FIG. 3. 4 may be displayed on the display unit 80. The preview image PI2 may include an overlapping face among the faces of a plurality of persons to be photographed, as illustrated in FIG. 4. As such, if the overlapping face among the faces of the plurality of people to be photographed exists in the preview image PI2, the user is notified, so that the user previews in the preview mode to acquire still image data including the faces of the plurality of people. When making a composition, etc. while looking at the image, the user can easily determine whether there is a hidden face among the faces. You can make sure you know it correctly.

The face recognition unit 51 of the digital photographing apparatus according to the present exemplary embodiment may recognize the face in the preview image through various methods. For example, the data on the main color of the face is pre-input, so that the face can be detected by determining whether there is data on the main color of the face among the preview image data, and the data on the pupil or the shape of the face is pre-input. It is also possible to detect the face by determining whether there is data on the pupil or the shape of the face among the image data, and the data on the T shape formed by the eyebrow part (or the eye part) and the nose part are pre-input Various methods may be used, such as detecting the face by determining whether there is data related to such a T shape among the preview image data.

The face overlap determination unit 53 may determine that there are overlapping faces when there are overlapping rectangles among the rectangles corresponding to each face included in the preview image recognized by the face recognition unit 51, for example. That is, quadrangles R1, R2, R3, R4, and R5 corresponding to each face included in the preview image recognized by the face recognizing unit 51, as illustrated in FIG. 5 schematically illustrating FIG. 5 and a portion thereof. If there are no overlapping rectangles, it is determined that there is no overlapping face, and the rectangles R1 and R2 corresponding to each face included in the preview image recognized by the face recognition unit 51 as shown in FIG. 7. If there are overlapping rectangles R2 and R3 among, R3, R4 and R5, it may be determined that there is an overlapping face. Since a region including eyes, nose, and mouth can be generally viewed as a region corresponding to a face, a quadrangle corresponding to each recognized face may be a quadrangle that places the eyes, nose, and mouth of each recognized face therein. . Of course, the rectangle may be a rectangle circumscribed to the edge of the recognized face.

Meanwhile, in addition to this, the face overlap determination unit 53 overlaps, for example, when the part recognized by the face recognition unit 51 as the face in the preview image is covered by another part recognized by the face recognition unit 51 as the face. You can also determine that there are faces. In addition, in addition to this, the face superimposition determination unit 53, for example, the part recognized by the face recognition unit 51 is not recognized as a face, so that when the total number of recognized faces decreases, there are overlapping faces. You can also judge. When some of the faces of the people to be photographed are covered by other faces or the body of another person, the total number of faces recognized by the face recognition unit 51 may be reduced. Of course, the user may intentionally exclude some of the people to be photographed by intentionally changing the composition and try to photograph only the faces of the remaining people, and in this case, the total number of recognized faces may be reduced. If a predetermined time elapses after the total number of faces is reduced, various modifications are possible, such as the face overlap determination unit 53 may determine that the faces do not overlap. Meanwhile, in addition to this, the face overlap determination unit 53 calculates an average distance between the faces recognized by the face recognition unit 51 in the preview image, and faces that are located at a significantly shorter distance than the average distance. In this case, it may be determined that there are overlapping faces.

As described above, it is possible to determine whether or not the overlapping faces exist through various methods and to notify the user when the overlapping faces exist, so that the user can easily determine whether there are any hidden faces among the faces in a short time. Can be.

Meanwhile, as described above, when the face overlap determination unit 53 determines whether there are overlapping faces, a rectangle corresponding to each recognized face may be used, and the display unit 80 may not preview the image. 5 to 7, the preview image may be displayed together with the quadrangles R1, R2, R3, R4, and R5 corresponding to each face recognized by the face recognition unit 51, as shown in FIGS. 5 to 7. . Accordingly, the user may easily recognize whether there are overlapping faces while looking at the rectangles R1, R2, R3, R4, and R5 displayed on the display unit 80. As shown in FIG. 7, displaying the overlapping rectangles R2 and R3 on the display unit 80 may indicate to the user that the overlapping faces exist. In addition, the display unit 80 may display the preview image together with the rectangles corresponding to each face recognized by the face recognition unit 51, but overlap the overlapping rectangles (R2 and R3 in FIG. 7) with other rectangles ( In the case of Figure 7 may be displayed differently from R1, R4, F5) so that the user can easily know. In this case, the overlapping rectangles (R2, R3 in FIG. 7) may be displayed in a different color from the other rectangles (R1, R4, F5 in FIG. 7), or the overlapping rectangles (R2, R3 in FIG. 7). ) Dotted lines and other rectangles (R1, R4, F5 in FIG. 7) in solid lines, or each side of the overlapping rectangles (R2, R3 in FIG. In this case, various modifications such as thicker than each side of R1, R4, and F5) are possible.

8 is a flowchart schematically illustrating a control method according to another embodiment of the present invention. "Start" in FIG. 8 may mean the start of the preview mode. First, the preview image is updated by generating the preview image data from the light incident on the image pickup device (S10). As described above, the preview mode displays a real-time video on the display unit. Each frame image of the real-time video may be referred to as a preview image. Here, updating the preview image means acquiring the first preview image immediately after the start of the preview mode, and once the preview image (frame image) is acquired, a new preview is used instead of the existing preview image (frame image). It means to acquire an image (frame image).

Thereafter, the method includes recognizing faces included in the preview image (S20), and determining whether there are overlapping faces among the recognized faces (S30). After the step S40, a step S50 of determining whether there is a still image acquisition signal is received from the user, and if not overlapping, a step S50 of determining whether there is a still image acquisition signal without going through the step S40. Going through. If there is a still image acquisition signal, a process of acquiring still image data is performed (S60), and if there is no still image acquisition signal, determining whether there is a still image acquisition signal from updating the preview image (S10) ( S50) is repeated again.

Of course, the control method as shown in FIG. 8 is merely an example, and the method includes recognizing faces included in the preview image from the preview image data from the light incident on the image pickup device, and overlapping faces among the recognized faces. It is enough to determine whether or not there is an overlap and to notify the user if it is superimposed, and to repeat these two steps until there is a signal from the user to acquire still image data.

According to the control method of the digital photographing apparatus according to the present embodiment, by judging whether or not the faces overlap, and notifying the user when it is determined that the overlapping faces exist, it is determined whether the user has a masked face among the faces. It can be easily identified accurately in a short time.

In step S30, when there are overlapping rectangles among the rectangles corresponding to each face recognized in step S20, it may be determined that there are overlapping faces among the recognized faces. In this case, the rectangle corresponding to each recognized face may be a rectangle that places the eyes, nose and mouth of each recognized face therein. Of course, it may also be a rectangle that circumscribes the recognized face.

Of course, in step S30, when a part recognized as a face is covered by another part recognized as a face, it may be determined that there are overlapping faces among the recognized faces, and a part recognized as a face is not recognized as a face. Therefore, when the total number of recognized faces decreases, it may be determined that there are overlapping faces among the recognized faces, and the average distance between the recognized faces is calculated and located at a significantly shorter distance than the average distance. If faces exist, various modifications are possible, such as determining that there are overlapping faces.

9 is a flowchart schematically showing a control method according to another embodiment of the present invention. The control method according to the present embodiment is different from the control method according to the embodiment described above with reference to FIG. 8, after the step S30 of determining whether there are overlapping faces among the recognized faces, the recognized angle The step of displaying the preview image on the display unit together with the squares corresponding to the face. In this case, when it is determined in step S30 that there is no overlapping face, the display unit displays the rectangles and the preview image corresponding to each face on the display unit (S43), and in step S30, the overlapping faces are present. If it is determined that the squares and the preview image corresponding to each face are displayed on the display unit, the squares corresponding to the overlapping faces are displayed in a different color from the other squares (S41). This allows the user to easily and quickly determine whether there are overlapping faces. Of course, in addition to displaying overlapping rectangles in a different color than other rectangles, you can also display overlapping rectangles with a dotted line and other rectangles with a solid line, or display each side of the overlapping rectangles thicker than each side of the other rectangles. Various variations of are possible.

The program for executing the control methods of the digital photographing apparatus according to the above-described embodiments and variations thereof in the digital photographing apparatus may be stored in a recording medium. Here, the recording medium may be a storage medium 80 as shown in FIG. 1, a memory 60 as shown in FIG. 1, or another separate recording medium.
