However, for clarity of explanation, in the specific embodiment of the present invention, a case of correcting the person image I will be taken as an example. In addition, it is possible to correct the length, thickness, etc. of the height, the arm, the leg, and the like of the person image I so that the height may be made larger. Explain the example of correcting an image.

If the person image I is displayed, step S30 may be performed in which a correction point A of the person image I is selected.

The user can select a desired portion for image correction from the displayed portrait image I, and the portion selected for correction is the correction point A. FIG.

The correction point A may be selected through various user input units 130 including a key pad, a dome switch, a jog wheel, and a jog switch, but may be selected through a positive pressure or electrostatic touch pad. It is preferable. That is, the user may select the correction point A through a touch operation in which a finger or the like touches or approaches the display unit 151.

The touch operation includes tapping or dragging the correction point A. FIG. Tapping refers to an operation of touching the inside of the region to be corrected, and dragging refers to an operation of forming a closed curve through a continuous operation to include the region to be corrected. For example, an operation of tapping the eye E of the person not supported I or dragging the eye E to be included.

When the correction point A is selected by the touch operation, the selected correction point A may be displayed by changing the color of the selected correction point A. FIG. By displaying the selected correction point A, the user can easily identify whether the desired part is correctly touched.

When the correction point A is selected, step S50 is displayed in which the corrected person image is displayed.

The corrected person image refers to an image in which the pre-correction image BI included in the correction point A selected by the user is changed to the post-correction image AI after undergoing a certain correction process. The process of changing the pre-correction image BI included in the selected correction point A into the post-correction image AI will be described in detail below.

If the image is corrected, step S70 of storing the corrected person image is performed.

Therefore, the user can load and display the corrected person image generated through one corrective operation in a desired situation.

6 is a diagram illustrating a process of selecting a specific area of a mobile terminal according to FIG. 4.

As shown in the drawing, the user may select the correction point A by touching or approaching the finger F to the display unit 151.

The correction point A may be near the point where the finger F is tapped, inside the closed curve drawn by the finger F, or the like, or may be an area where the finger F passes through several times. In the process of selecting the correction point A, the user can intuitively recognize the portion selected by the touch operation by inverting the color of the portion where the touch operation is performed.

7 is a flowchart illustrating a method of displaying the corrected person image of FIG. 4, and FIGS. 8 and 9 illustrate an operation of the mobile terminal according to FIG. 7.

As shown in these figures, the mobile terminal according to an embodiment of the present invention may include a step S51 of normalizing a person image.

When the pixel processing filter or the like is applied, the detail portion of the person image I may be removed to recognize the main portion of the person image I. FIG. For example, a relatively round shape may be recognized as a head in the person image I taken together with the background image. In addition, if the brightness of the outer portion is lower than the central portion of the portion recognized as the head portion, the portion with low brightness is hair and the portion with high brightness can be judged as a face. In this way, the part of the person image I may be identified from the entire displayed image.

That is, as shown in FIG. 8, when the normalization of the normalized image NI for the pre-correction image BI is normalized, the specific outline of the image is blurred, but the contrast of the contrast is clear, and the eyes having relatively low brightness and Eyebrows can be identified. However, the normalized image NI of FIG. 8 is exemplarily illustrated for clarity, and FIG. 8 is not a normalized image itself.

When normalization of the person image I is completed, a step S53 of extracting an image from the normalized person image is performed.

That is, it means that the image of the body part included in the correction point (A) by the user's selection is extracted. For example, as shown in FIG. 8, when the correction point A includes the eye E, a relatively low contrast portion is recognized as the eye to extract an image of the eye, and the portion is extracted. Recognize that it is the eye (E).

When the image is extracted, step S55 of searching for correction data corresponding to the image is performed.

The correction data means a correction direction applicable to each part of the body. For example, in the case of the jaw, a correction for thinning or thickening the jaw line is common, but in the case of selecting an eye, a correction for making the eye larger or smaller is common. In this way, the correction data is the data that is the basis for the different correction directions different for each body part. In addition to the correction direction, data related to specific correction contents may be stored in the correction data. That is, in the case of the eye, data about the degree of eyelid eyelid effect is obtained by forming a line at a position proportional to information such as eye size with respect to the eyelid eye.

When the correction data is found, step S57 of generating a correction image according to the correction data is performed.

As shown in FIG. 9, the eye E of the first person image II may be outer. When the direction of correction for the eyelid eye E1 is determined through the above-described normalization, image extraction, and correction data retrieval process, the pre-correction image BI, which is the eyelid eye E1, is based on the correction data. After correction, E2), the image AI can be corrected.

When the corrected image is generated, the process of displaying the corrected person image by combining the corrected image with the person image (S59) is performed.

As shown in FIG. 9, when the post-correction image AI is completed, the final post-image image FI, which is a double eye E1, is generated by combining the post-correction image AI with the initial portrait image II. On the other hand, as described above, not only the final person image FI is generated at once through the correction of the first person image II, but also a plurality of images from the first person image II to the last person image FI. It may change little by little as you go through the steps. In such a case, the person image changed as the user touches the correction point A once is displayed, and it is possible to perform several touch operations until the desired person image is displayed.

FIG. 10 is a flowchart illustrating an image correction method of a mobile terminal according to another embodiment of the present invention, and will be described with reference to FIG. 11 illustrating an operation of the mobile terminal.

As shown in these figures, the image correction method of the mobile terminal according to another embodiment of the present invention includes displaying the corrected images (T) (S57a).

The corrected images T mean various examples of correction that can be applied to the selected body part. That is, as shown in FIG. 11, when the body part included in the correction point A is the eye E, the double eyelid T1, the double eyelid T2, the small eye T3, Big eyes T4; and the like.

When the user selects an image to be corrected from among the displayed images T (S57b), a step (S57c) of generating a corrected person image by applying the selected image is performed. That is, when the eye T2 having the double eyelid is selected through a touch operation or the like, the eye T2 having the double eye coupler is corrected for the person image I.

In the above-described embodiments, the case where the shape of the body part such as the eye is changed has been described, but it is also possible to change the color tone such as the skin color of the selected correction point while the shape is maintained.

As described above, the present invention is not limited to the described embodiments, and various modifications and changes can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
