Description

A method for dividing a cartoon frame and displaying the divided cartoon frame on a portable terminal.

The present invention relates to a method for dividing a cartoon frame and a method for displaying a divided cartoon frame on a portable terminal, and more particularly, to a method for displaying cartoon content so that a cartoon can be easily viewed through a portable terminal having a small display unit.

Comic books that have been provided to readers through comic books printed on paper in the past can be viewed using a computer or a smart phone using the Internet or communication means. Particularly, since portable terminals such as smart phones are widely popular in recent years, users can view cartoons with less time and space.

However, most of the comic contents provided to the portable terminal are the same as the comic book published in printed matter or the screen composition provided in the web browser of the computer.

Since the size of the display unit of the portable terminal is small, when a content is displayed on the basis of a unit of a general comic book, there is a drawback that the picture and characters displayed on the screen are too small. Therefore, the user often has to manually apply the work for enlarging the screen, which is considerably inconvenient.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a method and apparatus for dividing a comic frame into a new type of content for displaying the comic so that the user can comfortably view the comic through the small- And displaying the divided cartoon frame on the portable terminal.

According to an aspect of the present invention, there is provided a method for dividing a cartoon frame, the method comprising: dividing a plurality of cartoon cuts and an outline surrounding an area in which a plurality of cartoon cuts are drawn, A method of displaying on a display unit, the method comprising: a first step of detecting an outline of an outline extracting unit and extracting an outline as an initial image frame; A second step of obtaining a primary cut image frame by cutting a first image frame based on horizontal lines or extension lines of vertical boundaries, which are extension lines of the horizontal boundaries of the cartoon cuts, in the first image frame; (N-1) -th cut image frame, the line cut section cuts the (n-1) -th cut image frame on the basis of the horizontal lines that are extension lines of the horizontal boundaries of the cartoon cuts or the vertical lines that are extension lines of the vertical boundary line A third step of obtaining an nth order cut image frame; When the line extracting unit fails to detect the horizontal line and the vertical line in the first image frame, the first cut image frame, or the nth cut image frame, the first image frame, the first cut image frame, or the nth cut image frame A fourth step of generating a cartoon cut frame by determining whether it is a cartoon cut; a fifth step in which, when the nth order cut image frame is a cartoon cut, the meta information generating unit generates position information on the first image frame of the corresponding cartoon cut frame; And a sixth step of generating a cartoon content including a cartoon cut frame and meta information and displaying the cartoon cut frame on the display unit of the portable terminal according to the matrix order of the position information.

At this time, n ≥ 2 natural numbers.

In the method of dividing a cartoon frame according to the present invention, the pre-processing unit may further include a preprocessing step of forming an outline surrounding the outermost boundary of the cartoon cuts at a predetermined interval before the first step.

And the step of acquiring the primary cut image frame or the n-th cut image frame uses the horizontal cutting line and the vertical cutting line alternately to cut the original image frame, the primary cut image frame, or the n-th cut image frame.

In this case, in the second and third steps, a line segment having a length of 80% or more including the boundary line of the cartoon cut is extracted as a horizontal (vertical) line in comparison with the length of the image frame.

In the second and third steps, when the line extracting unit extracts a plurality of horizontal (vertical) lines, the horizontal (vertical) line located near the center on the vertical (horizontal) is selected as the horizontal (vertical) cutting line.

If the size of the primary cut image frame or the nth cut image frame is equal to or larger than 95% of the size of the original image frame, the step of determining whether the cartoon cut determination unit is a cartoon cut may include determining whether the primary cut image frame or the n- We judge it as a cartoon cut frame.

Or the cartoon cut determination unit determines whether or not a cartoon cut is to be performed, the step of determining whether a pixel having the same gradation in the first image frame, the first cut image frame, or the nth cut image frame is 5% We judge it as a cartoon cut frame.

3 is a flowchart illustrating a method of generating cartoon content in the main server 100 and displaying the generated cartoon content on the portable terminal 200. [

A method of generating a cartoon cut frame P0 'by dividing a cartoon frame P0 in the main server 100 and displaying the generated cartoon cut frame P0' on the portable terminal 200 will be described with reference to FIGS. 1 to 3. FIG.

<Cartoon storage: S201>

The main server 100 receives cartoon frames from a cartoon maker and stores them. The cartoon maker may be an individual or a web server such as a portal site and a cartoon providing site.

&Lt; Pretreatment: S203 >

The preprocessing unit 110 of the main server 100 prepares a dummy outline L1 surrounding the outline L0 of the cartoon as shown in FIG. 4 and preprocesses a blank space in the outline L0 .

At this time, the outline (L0) surrounds the cartoon cut (㉠, ㉡, ㉢, ㉣, ㉤) to distinguish a cartoon area including a picture or a letter. .

This preprocessing is intended to facilitate the extraction of the outline of each image frame.

Because of the dummy outline L1 formed by the preprocessing unit 110, the outline L0 is clearly detected as a separate vertical and horizontal line in the subsequent process, so that the comic cut frame P0 of FIG. Can be clearly distinguished.

&Lt; Image frame extraction: S205 >

After the dummy outline L1 is formed, the outline extracting unit 120 of the main server 100 extracts the first image frame.

For this, the outline extracting unit 120 detects outlines (㉠, ㉡, ㉢, ㉣, ㉤) and selects a cartoon frame, which is an area inside the outline, as the first image frame P0.

The outline extraction unit 120 may use vertical / horizontal line edges.

<Line Extraction and Line Cutting: S207 to S217>

When the image frame is extracted, the line extracting unit 130 of the main server 100 extracts the horizontal line and the vertical line included in the image frame. In this case, the horizontal line and the vertical line are extended lines of the outer boundary lines of the cartoon cut (㉠, ㉡, ㉢, ㉣, ㉤) in the image frame, ㉤) is limited to a certain percentage or more of the length of the boundary line.

Then, the line extracting unit 130 cuts the image frame using the extracted horizontal line or vertical line. If a plurality of lines are detected, the line extracting unit 130 sets a priority order in the order of closest to the center of the frame area to set the cut line. The cutting of the image frame is performed after the cutting process is performed based on the horizontal cutting line, and the cutting process is performed based on the vertical cutting line if the horizontal line is not detected.

The process of extracting a line and cutting the extracted line will be described in more detail as follows.

5, the horizontal lines in the image frame extracted in step S202 include extension lines (①, ②, ③, ④, ⑤, and ⑤) of the horizontal boundaries of the entire cartoon cut (㉠, (㉠,., ㉢, ㉣, ㉤) in the ⑥, ⑦, ⑧) is limited to a certain ratio or more of the length corresponding to the boundary of the cartoon cut (㉠, ㉡, ㉢, ㉣, ㉤). At this time, the ratio of the lengths corresponding to the boundaries of the cartoon cuts (㉠,., ㉢, ㉣, ㉤) can be preset or adjusted by the user. For example, when the length corresponding to the boundary of a cartoon cut (㉠, ㉡, ㉢, ㉣, ㉤) is 80% or more of the total length, the line can be selected as a horizontal line.

The line extracting unit 130 selects the third to sixth lines (3, 4, 5, and 6) as horizontal lines in this manner.

If one horizontal line is extracted, the line extracting unit 130 selects the horizontal line as a horizontal cutting line. If a plurality of horizontal lines are detected as described above, the line extracting unit 130 extracts one line from the vertical to the center of the image frame Select horizontal cutting line. That is, the line extracting unit 130 selects the fourth line (4), which is one line near the center, as the horizontal cutting line.

6, the cartoon cutter 140 of the main server 100 cuts the cartoon frame P0, which is the first image frame, on the basis of the line, 6, the first and second primary cut image frames P11 and P12 are obtained.

The line cutting unit 140 cuts the image frame by alternately using the horizontal cutting line and the vertical cutting line. That is, the line extracting unit 130 selects a horizontal cutting line, and then selects a vertical cutting line.

Accordingly, when a vertical line is detected in the first primary cut image frame P11, the line cutting unit 140 cuts the first primary cut image frame P11.

If the ratio of the vertical length of the first comic cut (P) to the vertical length of the first-order cut image frame P11 is a short length to be selected as the vertical line, the horizontal line is again detected.

In the first primary cut image frame P11, since there is only one horizontal line in the third line (3), the line extracting unit 130 selects the third line (3) as a horizontal cutting line, (140) cuts off the first-cut video frame (P11).

When the first primary cut image frame P11 is cut once again, the first and second secondary cut image frames P21 and P22 are obtained as shown in FIG.

The line extracting unit 130 checks whether a horizontal line exists in the first secondary cut image frame P21 and extracts a vertical line since the first secondary cutout image frame P21 has no horizontal line at this time.

The method of extracting the vertical line by the line extracting unit 130 is similar to the method of extracting the horizontal line from among the extended lines of the horizontal boundaries of the cartoon cuts (㉠, ㉡, ㉢, ㉣, ㉤) ㉢, ㉣, ㉤) Extract lines with a certain percentage or more of the boundary line as vertical lines. Then, a vertical line near the center in the horizontal direction is selected as the vertical cutting line.

That is, the line extracting unit 130 detects an extension line of the vertical boundary of the first comic cut (P) in the first secondary cut image frame P21 as a vertical line, and selects a right border line near the center as a vertical cut line .

Then, the line cutting unit 140 cuts the first secondary cut image P21 using the vertical cut line, and as a result, the first secondary cut image frame P21 is divided into the first and second tertiary cut image P21, And is divided into frames P31 and P32.

The line extracting unit 130 selects a vertical cutting line in the first truncated image frame P31 and the line cutting unit 140 performs the cutting process again on the basis of the vertical cutting line P31, And obtains the cut video frames P41 and P42.

At this time, since the horizontal line and the vertical line are not detected in the first quadrant-cut image frame P41, the further cutting process is not performed.

If the second quadrant cut-off image frame P42 has no more horizontal lines and one vertical line exists, if the cutting process is performed on the basis of the one vertical line, the first and second error cut image frames ( P51 and P52 are obtained.

Since there are no horizontal lines and no vertical lines in the first and second error-cut image frames P51 and P52, no further cutting process is performed.

<Decision of cartoon cut: S219>

Then, the cartoon cut determination unit 150 of the main server 100 determines whether the horizontal and vertical lines are detected, such as the first and fourth error-cut image frames P41 and P51 and P52 (㉠, ㉡, ㉢, ㉣, ㉤) to be displayed on the display unit 210 using the image frames for which the cutting process has been completed.

For this purpose, the cartoon cut determination unit 150 determines whether the image frames whose cutting processes have been completed are image frames corresponding to cartoon cuts (㉠, ㉡, ㉢, ㉣, ㉤) or cartoon cut (㉠, ㉡, Is determined to be a video frame corresponding to the margin of the video frame.

The process of determining whether or not a cartoon cut (㉠,., ㉢, ㉣, ㉤) can be judged by using the size of the image frame or the gradation of pixels.

For example, when the size is used, the cartoon cut determination unit 150 determines that the image frame is a cartoon cut (㉠, ㉡, ㉢, ㉣, ㉤) when the image frame is larger than a predetermined size. This is based on the fact that in a comic book, one comic cut (㉠,., ㉢, ㉣, ㉤) is not drawn too small. For example, when the size of the video frame after the final cutting process is 5% or more of the size of the video frame corresponding to one page of the first comic, the comic cut determination unit 150 divides the video frame into a cartoon cut (㉠, ㉡, ㉣, ㉤) can be judged.

Alternatively, the cartoon cut determination unit 150 may determine whether or not the image is a cartoon cut (㉠, ㉡, ㉢, ㉣, ㉤) using the gradation of the pixel of the image frame that has undergone the final cutting process. This is because cartoon cuts (㉠, ㉡, ㉢, ㉣, ㉤) have various gradations in image frames due to pictures or letters.

Accordingly, the cartoon cut determination unit 150 determines that the image frame is a cartoon cut (㉠, ㉡, ㉢, ㉣, ㉤) when the minimum and maximum values of the gray levels of the pixels in the image frame are more than a certain range.

Alternatively, when a predetermined level, for example, 95% or more of the pixels of all the pixels of the image frame have the same gradation, the image cut-off determining unit 150 determines that the image frame is not a cartoon cut (㉠, ㉡, ㉢, ㉣, You can judge.

The cartoon cut determination unit 150 extracts only the frames corresponding to the cartoon cuts from the finally cut frames in this manner and generates the cartoon cut frames (㉠, ㉡, ㉢, ㉣, ㉤) as cartoon cut frames . At this time, the cartoon cut frame P0 'is configured to have the same ratio as the cartoon frame P0, including cartoon cuts (). Accordingly, the cartoon cut frame P0 'includes the image area A1 corresponding to the cartoon cut (㉠, ㉡, ㉢, ㉣, ㉤) and the other dummy area A2, and the dummy area A2 ) Is expressed as a region having a simple contrast so as not to disperse the user's line of sight.

&Lt; Generation of meta information and creation of cartoon content: S221, S225 >

In the course of dividing the cartoon frame through the above-described process, the meta information generator 160 of the main server 100 generates the meta information of the cartoon. FIG. 12 shows an example of meta information, and may include information on a title / volume / publisher / date / page / cartoon cut as shown in the figure.

In particular, the meta information includes the position coordinates of the cartoon cut (㉠, ㉡, ㉢, ㉣, ㉤) in the cartoon cut frame (P0 ').

The positional coordinates of the cartoon cut (㉠, ㉡, ㉢, ㉣, ㉤) are the information of the coordinates of the pixel where the cartoon cuts (㉠, ㉡, ㉢, ㉣, ㉤) are located in the original image frame (P0) If a cut (㉠, ㉡, ㉢, ㉣, ㉤) is a rectangle, it can contain the coordinates of four vertices.

The positional coordinates of these cartoon cuts (㉠, ㉡, ㉢, ㉣, ㉤) can be obtained by using the coordinates of the horizontal line and the vertical line in the process of cutting the image using the horizontal line and the vertical line.

Then, the cartoon content generating unit 170 combines the cartoon cut frame P0 'and the meta information to generate cartoon content.

<Display unit display: S225>

Through the steps S201 to S223, the cartoon cut frame P0 'and the meta information generated by the main server 100 are provided to the mobile terminal 200. [

The cartoon cut frame arranging unit 234 of the portable terminal 200 arranges the cartoon cut frames P0 'in the order displayed to the user using the meta information. At this time, the cartoon cut frame arranging unit 234 arranges the cartoon cut frame P0 'according to the order of the position coordinates included in the meta information. For example, the cartoon cut frame arranging unit 234 can arrange the cartoon cut frame P0 'so that the position coordinates are prioritized in the first image frame, have.

The size adjustment unit 232 of the portable terminal 100 converts the size of each comic cut frame P0 'into a size corresponding to the display unit 210. [ For example, when the second cartoon cutout is directly displayed on the display unit 210 of the portable terminal 200, the second cartoon cutout is displayed in a small size on a part of the display unit 210. [ This is because the original image frame P0 including a plurality of cartoon cuts is set to have a size corresponding to the display unit 210 on a one-to-one basis. Thus, the size adjuster 232 enlarges the cartoon cuts smaller than the size of the display unit 210 to correspond to the display unit 210, and displays the enlarged cartoon cutout on the display unit 110 as shown in FIG. The size adjusting unit 232 sets the image area A1 of the cartoon cut frame P0 'to be located at the center of the display unit 210. [

The details of the cartoon frame dividing method and the method of displaying the cartoon frame according to the present invention as described above can be implemented in various embodiments. For example, the size adjusting unit 232 and the cartoon cut frame arranging unit 234 included in the portable terminal 200 are implemented with the configuration of the main server 100, so that the portable terminal 200 simply displays the cartoon cut frame P0 ' ) In order to display the image.

In addition, the overall configuration of the main server 100 may be included in the portable terminal 200 so that the portable terminal displays the cartoon frames while dividing them.

Thus, it should be apparent to those skilled in the art that, although several embodiments have been described above, the present invention may be embodied in many other forms without departing from the spirit or scope of the invention. Accordingly, the above-described embodiments are to be considered illustrative and not restrictive, and all embodiments within the scope of the appended claims and their equivalents are intended to be included within the scope of the present invention.
