The display unit 60 may include a display control unit 61, a data driver 62, a scan driver 63, and a panel 64. The display controller 61 converts the image data provided from the controller 70 according to the display method of the panel 64 and outputs the converted image data to the data driver 62 and the scan driver 63. The data driver 62 provides a data signal, and the scan driver 63 provides a scan signal to the panel 64. The panel 64 displays an image according to the data signal and the scan signal. As the panel 64, a liquid crystal display panel (LCD), an organic light emitting display panel (OLED), an electrophoretic display panel (EDD), or the like may be used.

In the present exemplary embodiment, the display unit 60 may display classification information or images capable of deriving the same, and display the classified images stored according to the classification information. For example, a folder may be formed according to the classification information, and the result of storing the separated image in the folder may be displayed.

And a controller 70 for controlling the image file to be stored in a storage area corresponding to the classification information.

The controller 70 as described above will be described in detail with reference to FIG. 2.

Referring to FIG. 2, the controller 70 includes an image signal processor 71, a classification information generator 72, an image file generator 73, and an image file storage controller 74.

The image signal processing unit 71 performs gamma correction, color filter array interpolation, and color matrix so as to convert the image signal according to the human vision with respect to the image data input from the ADC 22. Image signal processing such as color matrix, color correction, and color enhancement is performed.

The classification information generation unit 72 generates classification information from image data input from the ADC 22 or image data for which predetermined image processing has been performed by the image signal processing unit 71. Specifically, face recognition information of at least one specific person may be set as classification information. Therefore, the classification information generator 72 may derive the face recognition information of the specific person from the image data.

In the method of deriving face recognition information from the image data, a template in which the luminance information of the face is previously recorded is formed, and the template is matched with the image data to determine whether there is data equivalent to the luminance information of the face from the image data. Therefore, if there is data equivalent to the brightness information of the face, face recognition information corresponding to the data may be derived.

Alternatively, the image data is converted into luminance data, color data, and chroma data, and the face is recognized based on the change in luminance in the vertical direction in the regions showing flesh color using the luminance data and the spatial distribution of the pixels of the regions. can do. Furthermore, the face may be recognized by detecting feature points of the face such as eyes and mouth.

The above-described face recognition method is exemplary and the present invention is not limited thereto.

The image file generator 73 compresses the image data to generate an image file. For example, when compressing still image data, an image file is generated by using a compression method such as JPEG, and when compressing motion image data, a compression method such as MPEG may be used. The image file generator 73 may generate an image file including the classification information derived from the image data.

The image storage controller 74 stores the image data in a storage area classified according to the classification information. Substantially, the image file generated as described above is stored in a storage area classified according to the classification information. The image storage control unit 74 controls to store the image file in a storage area corresponding to the classification information derived from the image data. Although the recording unit 40 or the external recording device 55 may be divided into a plurality of storage areas according to classification information in advance, a storage area corresponding to the classification information when the image storage control unit 74 stores the image file. And control to store the image file in the generated storage area.

When face recognition information is used as classification information, the image storage controller 74 determines the face recognition information from the image data and controls to store the image file in a storage area corresponding to the face recognition information. To this end, the storage area may correspond to the face recognition information in advance. Alternatively, a storage area corresponding to the face recognition information may be generated when the image file is stored, and the image file may be stored in the storage area.

In addition, the controller 70 may further include a classification information storage controller 75. The classification information storage control unit 75 controls the classification information, which is a criterion to be stored separately, to be stored in the recording unit 40 or the external recording device 55. For example, when setting face recognition information of a specific person as the classification information, first, the face of the specific person is photographed. The captured image is subjected to predetermined image signal processing by the image signal processing unit 71, and the classification information generation unit 72 derives face recognition information of a specific person from the captured image. The classification information storage control unit 75 controls to store the face recognition information of the specific person. The image file storage control unit 74 has an image having face recognition information having the same or similarity as that of the specific person's face recognition information stored by the classification information storage control unit 75 with respect to images captured thereafter. The file is determined, and the image file is classified and stored in the corresponding storage area.

 In addition, the controller 70 may further include a priority storage controller 76. When setting the plurality of classification information, the priority storage control unit 76 may control to store the priority with respect to the plurality of classification information. For example, when the classification information storage control unit 71 controls to store facial recognition information of A and B specific persons as classification information, the priority storage control unit 76 classifies A specific person preferentially to the B specific person. The priority can be controlled to be stored as a criterion. Accordingly, the image file may be stored in a storage area corresponding to the face recognition information of the specific person A for the image file including the specific people A and B. The priority may be set by an input of a user or the like, or may be automatically set. When a plurality of classification information is input and priority is set among them, the priority corresponding to each of the plurality of classification information may be stored together.

The controller 70 includes a CPU 77 that controls the overall operation of the components, a memory 78 that stores data for arithmetic processing of the components, and arithmetic processing results. In addition, the memory 78 stores a program for operating the digital photographing apparatus 100.

It may be formed by the same element. In addition, the connection relationship between the block diagrams may be determined by deriving classification information from an image photographed by the control method of the digital photographing apparatus 100 according to the embodiment, and classifying the information according to the classification information to store the image. As illustrated, more connection relationships may be included if necessary, for example, for the control of the imaging device 21 and the ADC 22 in order to effectively capture an image.

3 is a flowchart illustrating a control method of a digital photographing apparatus according to the present invention.

Referring to FIG. 3, an automatic classification storage mode is selected and set (S11).

Then, it is determined whether the classification information is registered (S12).

If the classification information is not registered, the classification information is registered (S13). When a plurality of pieces of classification information is to be registered, the priority of the plurality of pieces of classification information may also be set. Face recognition information can be used as the classification information. For example, referring to FIG. 4, a user may register face recognition information of specific persons A, B, and C as classification information. A user photographs the faces of A, B, and C by using a digital photographing apparatus, generates a face image, and stores the face image. Then, face recognition information of each of the specific persons is generated from the face image. Since there is a plurality of classification information, priority can be set and registered together among the A, B, and C specific persons.

 When the classification information is registered, it is determined whether a plurality of classification information is registered (S14). When a plurality of classification information is registered, priority is set between the plurality of classification information (S15).

For example, referring to FIG. 5, in the case of using face recognition information of A, B, and C specific persons as classification information, the same priority is given to A specific person and B specific person, and A specific person and B are assigned to C specific person. It can be set to give a specific person a high priority. Accordingly, the first storage area A & B corresponding to the face recognition information of the specific persons A and B, the second storage area A corresponding to the facial recognition information of the specific person A, and the third corresponding to the facial recognition information of the specific person B The storage area B and the fourth storage area C corresponding to the face recognition information of the specific person C may be generated. The storage area may be divided according to the classification information later when storing the video file.

When a plurality of classification information is not registered, image data is generated (S16). The video data is also generated after the classification information registration (S15). The image data is formed by photographing a subject, and is formed for recording in accordance with an input of a release signal.

Then, classification information is derived from the image data, and it is determined whether the classification information is singular (S17).

If the classification information is singular, the image data is stored in a storage area corresponding to the singular classification information (S18).

If the classification information is not singular, it is determined whether the plurality of individuals (S19).

When a plurality of classification information is derived from the image data, the priority of the plurality of classification information is determined (S20). The video data is stored in a folder corresponding to the high-priority classification information (S21).

For example, referring back to FIG. 5, when photographing A and B specific persons to generate first image data, face recognition information of A and B specific persons may be derived from the first image data, and the A and B specific persons may be derived. When the face recognition information has the same priority, the first image data may be separated and stored in the first storage area A & B corresponding to the face recognition information of the A and B specific persons.

As another example, when photographing A and C specific persons to generate second image data, face recognition information of A and C specific persons may be derived from the second image data, and the face recognition information of the A specific person is C. When having a higher priority than face recognition information of a specific person, the second image data may be stored in a second storage area A corresponding to the face recognition information of the specific person A.

If classification information is not derived from the image data, the image data is stored in a storage area set as a default (S22). After substantially compressing the image data to form an image file, the image file may be stored in a corresponding storage area.

Then, it is determined whether to end photographing (S23), in which case, photographing is terminated. Otherwise, photographing is repeated to generate image data again (16).

Subsequently, if the storage area is checked, the image data may be separated and stored according to the classification information. For example, referring to FIG. 6, when the second storage area A is identified, only the image data including the A specific person is separated and stored without including the A and B specific people.

According to the above-described embodiments of the present invention, an image photographing a subject may be classified and stored according to the subject. Therefore, when checking an image of the subject, only the image of the subject may be selectively checked without checking all stored images.

The present invention also provides a recording medium in which the control method of the digital photographing apparatus is recorded by a program executable in a digital device. Computer-readable recording media include all types of recording devices that store data that can be read by a computer system. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disks, optical data storage devices, and the like, which may also be implemented in the form of carrier waves (for example, transmission over the Internet). Include. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. And functional programs, codes and code segments for implementing the present invention can be easily inferred by programmers in the art to which the present invention belongs.
