DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout the specification and claims. The description will be omitted.

1 is a block diagram showing a schematic configuration of a photographing apparatus according to an embodiment of the present invention.

1, the photographing apparatus according to the present embodiment includes a camera unit 10, a display unit 30, a storage unit 50, and a control unit 70. The control unit 70 includes an image processing unit 72 An object recognizing unit 74, and a photo generating unit 76. [0035]

The camera unit 10 is provided for a camera function and may be equipped with a lens or the like, and a detailed description of the camera unit 10 will be omitted because a mobile phone or the like equipped with a digital camera and a camera module is now available.

The display unit 30 is for displaying an image photographed by the camera unit 10, and may be, for example, a liquid crystal display, a touch screen, or the like. Hereinafter, a touch screen for receiving specific information from a user will be described as an example of an image for convenience of explanation.

The storage unit 50 stores data processed by the control unit 70 and captured by the camera unit 10. For example, the captured image data (which may be, for example, an image file) The data stored in the storage unit 50 will be described later in detail.

The image processing unit 72 of the control unit 70 outputs a preview image according to an external image captured by the camera unit 10 through the display unit 30 and displays a current input image File (hereinafter referred to as a photographed image). Generally, when a camera function provided in a smart phone or the like is executed, an input image is displayed on a display module such as a touch screen provided as a preview image. The input image is not generated as a file, As shown in Fig. Accordingly, the user can take a desired picture while checking the preview image.

In particular, the control unit 70 according to the present embodiment recognizes a specific object according to user input in the input image. That is, when the preview image is outputted through the screen, the user can select a specific object from the preview image, and the control unit 70 distinguishes the object selected by the user.

The object recognizing unit 74 of the control unit 70 distinguishes and recognizes objects selected by the user from the preview image output as described above. Object recognition technology for recognizing objects such as people and objects using an outline detection technique in an image is a technology widely used today and will be obvious to a person skilled in the art, so a detailed description of the object recognition will be omitted.

The image processing unit 72 divides the object recognized by the object recognizing unit 74 and the remaining part into different areas and applies the effects to the divided areas in different ways to perform image processing. As an easy example, you can treat the object as a blurred image with the rest of the area coming out sharply. The image to which the effect is applied can be generated and displayed as a preview image. Hereinafter, an object-based image is referred to as an object-based image for convenience of explanation, and an image processing method of the object and the remaining portion will be described later.

The photo generating unit 76 generates a photo file corresponding to the image processed by the image processing unit 72 in accordance with the photo-taking command. That is, when the photograph photographing command is input, the photograph generating unit 76 generates a photograph file in which the current input image is processed as an object-based image by the image processing unit 72, and stores the generated photograph file in the storage unit 50.

Hereinafter, a process of photographing a subject by dividing an object will be described.

FIG. 2 is a flowchart illustrating an object-based photographing process according to an exemplary embodiment of the present invention. FIG. 3 is a view illustrating a preview image and an object-based image in the photographing device according to an exemplary embodiment of the present invention .

Referring to FIG. 2, when a camera function is executed (S210), a preview image according to an input image is output (S215).

If the user input is recognized (S220), it is determined whether it is a photograph photographing instruction or an object photographing instruction (S225, S235).

3 showing a smartphone 300 as a photographing device, for example, a photographing instruction is displayed as a user interface screen at a position separate from the preview image 310 (or displayed on one side of the preview image 310) May be recognized by a user input to the photographing button 312. [ It goes without saying that a photographing instruction may be inputted by a photographing button (not shown) provided mechanically on one side of the photographing apparatus. Or a screen touch to the preview image 310 may be recognized as a photograph photographing instruction. If a special object such as a person, an object, or an animal is not recognized at a point where the user touches the input, have.

The object shooting command may be a user touch input to a point where the object is located, which will be described later.

Referring again to FIG. 2, in the case of a photograph photographing command, the current input image is subjected to an image process to generate a photograph file (photograph) (S230).

If the user input is an object shooting command, the object based on the user input in the preview image is distinguished (S240).

3, when a user inputs an object shooting command for an arbitrary object 320 such as a person in the preview image 310, the object 320 is identified. The user input is displayed on the touch screen, for example, And may be a touch input to a position where the object is displayed. That is, the photographing apparatus identifies an object corresponding to a point (a specific position of the preview image) according to the touch input of the user. Of course, the touch input is only an example. According to another example, a mouse pointer may be displayed on a preview image, and a user interface may be provided to select an object by operating a mouse pointer. According to another embodiment, each object in the preview image is recognized and displayed together with identification information (e.g., a number), and the user can select any one by inputting the corresponding identification information.

Referring again to FIG. 2, when an object according to a user input is distinguished, the object and the rest are divided into respective regions (hereinafter, referred to as an object region and a background region), and effects (Which may be selected at that point in time) (S245). As an easy example, the object region can be used as it is and the focus region can be blurred and blurred. Of course, this is merely an example, and according to another example, the object area may be color-processed and the background area may be processed in black and white. As another example, the object region may be processed in black and white, and the background region may be color processed and blurred.

When the generation of the object-based image is completed, the object-based image is displayed as a preview image (hereinafter referred to as an effect-applied preview image) so that the user can check it (S250). That is, as shown in 330 of FIG. 3, an effect-applied preview image according to an object-based image that is processed differently based on an object selected by a user is displayed.

Although only one object is selected in this embodiment, this is only an embodiment, and two or more objects may be selected at the same time. For example, if a user touches a point where two objects are simultaneously displayed with two fingers, each object is recognized and an object-based image according to two objects can be generated. As another example, if a user touches a point at which one object is displayed with a finger and moves to a point where the other objects are displayed in a drag manner, And an object-based image corresponding thereto can be generated. That is, the user can select a plurality of objects with a single drag input.

Although not shown in the drawing, according to another embodiment, the photographing apparatus can distinguish objects from a preview image and display (e.g., display objects with a red dotted line or the like) so that the user can recognize the object have. In this case, the user would be able to select one or more of the displayed objects.

When a subsequent shooting command is input, a shooting image corresponding to an object-based image (i.e., an effect applying preview image) may be generated.

In this embodiment, after displaying the effect applying preview image, a photo file corresponding to the effect applying preview image is generated according to another photographing command of the user. According to another embodiment of the present invention, for the sake of convenience of the user, only an input for selecting an object (for example, an input for touching a position where a desired object is displayed among a preview image displayed on a touch screen) May be generated immediately.

The object-based photographing method according to the present invention can be implemented as a computer-readable code on a computer-readable recording medium. The computer-readable recording medium includes all kinds of recording media storing data that can be decoded by a computer system. For example, it may be a ROM (Read Only Memory), a RAM (Random Access Memory), a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, or the like. In addition, the computer-readable recording medium may be distributed and executed in a computer system connected to a computer network, and may be stored and executed as a code readable in a distributed manner.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that various modifications and changes may be made.
