The imaging unit 110 captures a subject and converts the image of the subject into an electrical signal. The imaging unit 110 includes a lens 111 for passing image light from a subject and an imaging device (not shown) for converting the passed light into an electrical signal. As an imaging device, a complementary metal oxide semiconductor (CMOS) or a charge coupled device (CCD) may be used.

The frame generator 120 recognizes a subject from an image of the subject captured by the imaging unit 110 and generates a frame displaying the outline of the subject. Therefore, the frame generator 120 may include an object recognizer and a UI generator.

That is, the object recognition unit recognizes a subject in the image captured by the imaging unit 110. The method of recognizing the subject may use a conventionally disclosed method. For example, it is possible to use a method of extracting a boundary of an object through frequency analysis of the captured image. However, the present invention is not limited thereto, and various object recognition methods may be used. Face recognition may also be an example of a method of recognizing the subject.

Meanwhile, when the subject is recognized, the UI generator generates a frame representing the outline of the recognized subject. The frame may include the entire subject or may include only a part of the subject. When the entire subject is included, the outermost points of the recognized subjects may be extracted and generated. On the other hand, the frame surrounding only the human face may include only a part of the subject.

The auxiliary UI generator 130 generates an auxiliary UI displaying a distance from the outer boundary of the image generated by the frame generator 120.

The auxiliary UI may be displayed by lines connecting the frame and the outer boundary of the image. For example, when a quadrangular frame is generated, four lines may be connected from each side of the frame to the outer boundary of the image facing each other. On the other hand, the auxiliary UI may further include a number indicating the distance from the frame to the outer boundary of the image on one side of the line in order to allow the user to intuitively recognize the position of the frame.

Meanwhile, the auxiliary UI generator 130 may convert the colors of the generated lines or numbers under a specific condition. For example, the auxiliary UI may be converted when the frame is located at the center of the captured image. Alternatively, when the frame is located at a specific position set by the user, it may be possible to convert the color of the auxiliary UI. Alternatively, the auxiliary UI generator 130 may change the size or thickness of the generated lines or numbers.

Furthermore, it may be possible to form some of the lines of the auxiliary UI in the shape of an arrow so that the user can more easily recognize in which direction the subject should be moved. It would also be possible to form as the arrow proceeds.

The frame generator 120 and the auxiliary UI generator 130 may regenerate and update the frame and the auxiliary UI by using the newly captured image when the size of the subject changes or changes due to a zoom-operation. will be.

The display 140 displays a subject, a user interface (UI) provided according to manipulation of buttons by a user, a preview image in a preview mode, a playback image in a playback mode, and the like. In addition, the frame generation unit 120 and the auxiliary UI generator 130 may display the frame and the auxiliary UI, respectively generated. The display unit 140 may include a display driver that performs a function of reproducing an image such as image data, an image file, and the like, and a display screen displaying the reproduced image so that a user can check it.

The storage 160 may store various signals, data, and algorithms for operating the digital image processing apparatus 100. RAM may be used as a temporary storage medium for temporarily storing data, and the RAM may be a dynamic random access memory (DRAM) or the like. A storage medium EEPROM (electrically erasable and programmable read only memory) in which the algorithm is stored may be used. In addition, a memory card or the like may be used as a storage medium for storing image files photographed by the imaging unit 110 and attribute information of the image files. The memory card or the like may be internal or external.

The controller 170 performs overall control of the digital image processing apparatus 100 according to the present invention. The controller may receive an input signal from the user input unit 150, generate a control signal corresponding to the input signal, and apply it to a portion to which the control signal is applied. In addition, the digital signal may be converted into a digital signal after converting the electrical signal applied from the imaging unit 110 into a displayable image signal. The video signal processing refers to a series of signal processing such as white balance processing, noise removal, and color correction. In addition, an image file is generated using the video signal generated by the shutter-release button signal input. The image file is compressed and generated in JPEG format according to the Exif file format which is an image file standard.

In this way, a frame representing the outline of the subject is generated, and the frame is displayed to the user at a distance away from the outer boundary of the image so that the user can easily compose the composition at the time of shooting. In addition, in a specific composition, the user can indicate that the subject is in a desired position, thereby making it easier to compose the desired composition.

Hereinafter, referring to FIGS. 3 to 5, the composition of the composition using the auxiliary UI will be described in detail.

3 is a diagram illustrating an operation of a digital image processing apparatus according to an embodiment of the present invention. 2 and 3, in FIG. 3A, the digital image processing apparatus 100 captures an image of one person 300 as a subject. After recognizing the person 300, the frame generation unit 120 generates and displays a frame 310 surrounding the person 300. The auxiliary UI generator 130 generates and displays the lines 320 connecting the upper, lower, left, and right boundary lines of the frame 310 and the boundary of the image. One side of the lines 320 generates and displays a number 321 representing a distance from the boundary of the image to the boundary of the frame 310.

The user allows the person 300 to be located at the center of the image as shown in FIG. The user may move and execute the digital image processing apparatus 100 or the person 300 may move and execute the same. As shown in FIG. 3B, when the person 300 is located at the center of the image, the auxiliary UI generator 130 may make the thickness of the lines serving as the auxiliary UIs thicker. In FIG. 3B, only the lines of the auxiliary UIs are changed, but the numbers may also be thickened. Alternatively, as described above, it may be possible to convert the color of at least one of the lines 320 or the numbers 321 of the auxiliary UI.

As such, when the subject is positioned at the center of the image, the user may easily recognize that the subject is at the center of the image by applying a change to the auxiliary UI. In addition, the user can easily know which direction to move the subject to the center of the image by the auxiliary UI.

4 is a diagram illustrating an operation of a digital image processing apparatus according to another embodiment of the present invention. Referring to FIGS. 2 and 4, in FIG. 4A, after recognizing the person 400 as in FIG. 3A, a frame 410 and auxiliary UIs 420 and 421 are generated and displayed. . On the other hand, in the case of Figure 4 (a) the person 400 is located in the lower left from the center of the image. That is, the user must move the person 400 to the upper right in order to center the person 400. Accordingly, the auxiliary UIs on the left and bottom of the auxiliary UIs 420 and 421 may be represented in the form of arrows. By expressing in this way, the user can intuitively determine the direction to move the subject.

As shown in (b) of FIG. 4, when the person 400 is positioned at the center, all the auxiliary UIs 420 and 421 may be represented in the form of arrows.

As such, since the auxiliary UI is changed when the subject is positioned in the center of the image, the user can easily recognize that the subject is positioned in the center of the image. In addition, the user can easily know which direction to move the subject to the center of the image by the auxiliary UI.

3 and 4 illustrate that the user takes a picture in a composition in which the subject is in the center, but as mentioned above, the subject is located at a specific location, for example, a location according to a composition preset by the user. In that case it would be possible to change the auxiliary UI. In this case, in FIG. 4, the auxiliary UI may display a moving direction of the arrow so that the subject moves to a position according to the set composition.

5 is a view showing the operation of the digital image processing apparatus according to another embodiment of the present invention. Referring to FIGS. 2 and 5, as shown in FIG. 3A, after recognizing the person 500, the frame 510 and the auxiliary UIs 520 and 521 are generated and displayed. .

However, when the person 500 is determined to be too small to perform the zoom-motion or when the person 500 approaches, the size of the person 500 and the size of the frame do not match. Therefore, as shown in (b) of FIG. 5, the frame generator 120 recognizes the person 500 again, generates a frame 511, and the auxiliary UI generator 130 generates and displays the auxiliary UI again.

This allows the user to compose the best composition in each situation.

6 is a flowchart illustrating a control method of a digital image processing apparatus according to an embodiment of the present invention.

Referring to FIG. 6, once the power of the digital image processing apparatus is turned on, an image of a subject is captured (S60).

The subject is recognized 61 in the captured image, and a frame displaying the outline of the subject is generated (S62). The method of recognizing the subject is omitted in the description of FIG. 2.

In operation S63, an auxiliary UI indicating a distance from an outer boundary of the captured image to the frame is generated using the generated frame. The auxiliary UI may include lines connecting the outer boundary of the image and the frame and a number located at one side of the lines.

The image of the subject is continuously captured in real time, and it is determined whether the position or the size of the subject has been moved (S64).

When the position or size of the subject changes, the operation of generating the frame and the auxiliary UI is repeated (S61 to S63). On the other hand, if there is no change in the position or size of the subject, it is determined whether the frame is located at the center of the image or a specific position set by the user (S65).

If the frame is not located at the center or a specific position of the image, the previous steps (S61 to S64) are repeated again, and if the frame is located at the center or a specific position of the image, the auxiliary UI may be recognized. The color is converted (S66). Alternatively, as shown in FIG. 3 or FIG. 4, the user may be recognized by changing a thickness or an arrow of the auxiliary UI.

In this way, a frame representing the outline of the subject is generated, and the frame is displayed to the user at a distance away from the outer boundary of the image so that the user can easily compose the composition at the time of shooting. In addition, by displaying the object in the desired position in the center or a specific position, the user can easily compose the desired composition by zooming.
