As shown in FIG. 1, in the control method of the electronic device 100 for automatically measuring the size of letters, letter spacing, and height of the center point according to one aspect of the present invention, the electronic device 100 performs automatic measurement. The size of each of the plurality of letters constituting the text included in the target image can be calculated (S110), and based on the calculated sizes, the letter spacing between neighboring letters can be calculated (S120).

In addition, the electronic device 100 identifies the center point of each of the plurality of letters (S130) and identifies the center line for the text based on the center point (S140), so that each of the plurality of letters is identified based on the center line and center point. Calculate the displacement with respect to the center line (S150).

In one embodiment, the electronic device 100 includes a server, a smartphone, a tablet personal computer, a mobile phone, a video phone, a laptop PC, and a netbook computer. ), a laptop computer, a personal digital assistant (PDA), a portable multimedia player (PMP), or a wearable device.

As shown in Figure 2, the image subject to automatic measurement is an image containing text (e.g., spelling, one letter, word, word, syllable, sentence, paragraph, etc.) generated in real time by a person's handwriting. It may be generated by input from the user terminal 200 through the communication unit 120, or by handwriting input from the user through the input/output module 140. Additionally, it may be an image previously stored in the memory 110.

Letters are symbols of a certain system that constitute the text. For example, in the case of Figure 2, 'Yeo', 'Bo', 'An', 'Gyeong', 'An', 'Bo', 'I', 'Ne' A total of 13 letters of ', 'An', 'Gyeong', 'An', 'Bo', and 'Yeo' make up one text, and in the case of English, the electronic device 100 uses one alphabet. It can be identified by one letter.

Meanwhile, when the electronic device 100 performs step S110, the electronic device 100 generates a horizontal (x) axis and a vertical (y) axis for each of the plurality of letters, as shown in FIG. 3, Coordinates (ex, (x, y)) can be created based on the horizontal and vertical axes.

Accordingly, the electronic device 100 calculates the horizontal and vertical lengths of each of the plurality of letters based on the coordinates, and thus calculates the size of each of the plurality of letters based on the horizontal and vertical lengths. .

Specifically, the electronic device 100 identifies at least one stroke constituting one letter and generates a plurality of coordinates obtained as (horizontal value, vertical axis value) where a plurality of vertices for each identified stroke are located. do. For example, 'I see your glasses, I see your glasses,' in Figure 3 consists of a total of 52 strokes, and the coordinates for the vertices of each stroke are calculated, and among the coordinates calculated for all the strokes that make up one letter, (minimum, minimum ), (minimum, maximum), (maximum, maximum), (maximum, minimum) can be created as coordinates for the corresponding character.

Accordingly, the electronic device 100 calculates the distance between the (minimum, minimum) coordinates among the obtained plurality of coordinates and the (maximum, minimum) coordinates among the obtained plurality of coordinates as the horizontal length, and calculates the horizontal length for the corresponding character. Among the plurality of coordinates obtained, the (maximum, minimum) coordinate and the distance between the (maximum, maximum) coordinates among the plurality of obtained coordinates are calculated as the vertical length, and the value multiplied by the horizontal length and the vertical length is calculated for the corresponding character. It can be calculated by size.

At this time, as shown in Figure 3, the size of the letter represents the area of the minimum size right-angled square containing the letter, and the right-angled square represents a plurality of coordinates A, B, and C for the letter. Includes a point on a side and a vertex.

Meanwhile, as shown in FIG. 4, when the electronic device 100 performs step S120, the electronic device 100 determines the maximum horizontal axis coordinate of each of the plurality of letters based on the plurality of coordinates generated in step S110. value, and the minimum value of the horizontal axis coordinate of each of the plurality of letters. Accordingly, the electronic device 100 identifies the first letter and the second letter among the two neighboring letters for the plurality of letters constituting the text. The character spacing, which is the space between the second letters, can be identified.

Specifically, in a plurality of letters, the electronic device 100 determines the minimum horizontal coordinate value closest to the maximum horizontal axis value for the first character among the horizontal axis coordinates of other characters that exceed the minimum horizontal coordinate value for the first character. You can obtain the letter you have as the second letter.

The electronic device 100 obtains a value obtained by subtracting the minimum horizontal coordinate value for the second character from the maximum horizontal coordinate value for the first character as the letter spacing between the first and second characters.

For example, for 'show' in Figure 4, if the first letter 'Bo' and the second letter 'Yeo' overlap each other as shown, the letter spacing will be calculated as a negative number, such as '-12.3846'. You can.

On the other hand, for 'Ine' in Figure 4, when the first letter 'I' and the second letter 'Ne' are spaced apart from each other as shown, the letter spacing is calculated as a positive number as calculated as '15.17389'. It can be.

Meanwhile, when the electronic device 100 performs step S130, the electronic device 100 determines the minimum horizontal coordinate value, maximum horizontal coordinate value, minimum vertical coordinate value, and maximum vertical axis coordinate for each of the plurality of characters, based on the coordinates. Center coordinates with equal distances to the values can be calculated, as shown in FIG. 5 .

Thereafter, when the electronic device 100 performs step S140, the electronic device 100 identifies a third character having the smallest horizontal coordinate value among the plurality of characters and the smallest horizontal coordinate value among the plurality of characters. By identifying the fourth letter with the maximum value, the center point of the third letter is set as the starting point, the horizontal coordinate value of the center point of the fourth letter is set as the end point, and a center line with a slope of 0 can be identified.

For example, as shown in FIG. 5, the electronic device 100 includes the center point of the third letter 'Yeo' as a starting point, and the vertical axis coordinate value of the center point of the third letter and the fourth letter 'Yeo' A center line with a slope of 0, which has a coordinate composed of the horizontal axis coordinate value of the center point as an end point, can be identified.

Accordingly, when the electronic device 100 performs step S150, the electronic device 100 identifies the vertical axis coordinate value of the center point of each of the letters excluding the third letter among the plurality of letters, and identifies the identified The normal length and direction of each vertical axis coordinate value with respect to the center line are calculated as the displacement with respect to the center line.

For example, as shown in FIG. 5, the electronic device 100 calculates the displacement by subtracting the vertical axis coordinate value of each letter from the fixed vertical axis coordinate value of the center line. Therefore, when the displacement is a positive number, it is greater than the center line. It can be identified as a low position, and if the displacement is negative, it can be identified as a position higher than the center line.

'Gyeong', the 4th letter constituting the text in Figure 5, is located lower than the center line, so the displacement is calculated as '2.566101', which is a positive number, and 'Gyeong', the 10th letter constituting the text, is located higher than the center line. Since there is, the displacement is calculated as '-12.468', which is a negative number.

Meanwhile, when the electronic device 100 acquires the letter spacing between the first and second letters, the electronic device 100 changes the letter spacing to the first letter spacing preset for spacing when the letter spacing is greater than a threshold distance, On the other hand, if the letter spacing is less than the critical distance but is a negative number, the letter spacing can be changed to a second letter spacing preset for the spacing between neighboring letters.

At this time, when the electronic device 100 changes the letter spacing to the preset second letter spacing, the electronic device 100 calculates a displacement in which the minimum value of the horizontal axis coordinate of the second character is changed as the letter spacing is changed to the second letter spacing, Among a plurality of letters, letters with a minimum horizontal coordinate value greater than the minimum horizontal coordinate value of the first letter are identified, and the displacement resulting from the change in the minimum horizontal coordinate value of the second letter calculated is added to the horizontal axis coordinates of each identified letter. , by creating an image with overall corrected letter spacing, corrections can be performed to improve readability of the entire text.

In an embodiment, the electronic device 100 adjusts the size of each of the plurality of letters, the space between adjacent letters, and the height so that the fixed vertical coordinate value of the center line is the vertical coordinate value of the center point, as shown in FIG. 6. Likewise, the readability of text can be improved by uniformly proofreading.

Specifically, the electronic device 100 enlarges or reduces the center point included in each of the plurality of letters constituting the text of the first image to have a rectangle of the same size as the rectangle created for the third letter. A second image is acquired, and coordinates for each of a plurality of letters of uniform size constituting the text of the second image are regenerated.

The electronic device 100 identifies the order of the first letter and the second letter among the plurality of letters based on the first image, and reproduces the coordinates and threshold distance for each of the plurality of texts in the second image. Based on , the letter spacing is changed to one of the first letter spacing and the second letter spacing, or the letter spacing between the first and second letters of the second image is maintained to obtain a third image with uniform letter spacing.

Thereafter, the electronic device 100 identifies the third and fourth letters among the plurality of letters in the third image, obtains the center line based on the third and fourth letters, and obtains the center coordinates of all the plurality of letters. For , by converting to include a vertical extrusion coordinate value that is the same as the fixed vertical axis coordinate value of the center line, a fourth image including text with uniform size, spacing, and height can be obtained, as shown in FIG. 6.

In an embodiment, when the electronic device 100 performs step S110, the electronic device 100 separates a plurality of letters constituting the text based on strokes, but when the letter spacing between neighboring letters is less than the critical distance. , obtain words formed by neighboring letters.

The electronic device 100 identifies a first word with a noun meaning included in the acquired word phrase, and determines whether the first word violates the context of the text. Specifically, when a fifth letter whose letter spacing is less than the threshold distance is identified for a first word, the electronic device 100 determines that the minimum horizontal axis coordinate of the identified fifth letter is at least one sixth letter constituting the first word. If the value is smaller than the smallest horizontal axis coordinate value among the letters, the electronic device 100 may determine that the first word has a noun meaning but does not form a sentence formed by the text. At this time, the fifth letter is an element that performs a grammatical function, such as a particle or an ending, and is attached to the back of the first word to form a phrase. However, if it is placed in front of the first word, the fifth letter is a phrase or a text composed of the phrase. Since the context for (sentence) is violated, the electronic device 100 may compose the second word by recombining the fifth letter and the strokes constituting the first word.

At this time, the memory 110 stores audio pronunciation of the text, and the electronic device 100 can determine whether the first word is a word included in the text based on the audio.

If the first word is a word not included in the text, the electronic device 100 reassembles the letters constituting the second word based on the stroke and re-determines whether the second word is a word included in the text based on the audio. can do.
