Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an image editing system for implementing a digital image editing method according to the present invention.

Referring to FIG. 1, a computer system 100 executing software and a camera 200 and a monitor 300 capable of capturing an image of a subject are configured, and the computer 100 displays an image transmitted from the camera 200. It consists of an image input unit 110, a main program unit 120 to input, a library unit 130 to provide a library to create another executable file, and a screen display unit 140 to display a GUI on the monitor 300. The camera 200 may be configured as a universal serial bus (USB) standard camera in addition to a CCD camera that provides a television standard signal (NTSC).

2 is a block diagram of a GUI screen for performing a digital image editing method according to the present invention.

In Fig. 2, the GUI screen 10 shows the entire web screen for image editing. The GUI screen 10 includes a button 10a, a script mode area 10b, and an icon 10c for performing a dropdown function. ), History area 10d, arbitrary video screens 10e and 10f, and enlarged window 10g.

Each button 10a is matched to an image processing algorithm, and when the button 10a is pressed, a drop down button appears. If the icon 10c is frequently used or an important function among the buttons 10a, the icon 10c performs a function corresponding to the button 10a to be easily used by the user.

The script mode area 10b provides an image processing algorithm corresponding to the button 10a in the form of an expression, and includes a function name indicating a function corresponding to a function of the button 10a provided in the GUI screen 10. If necessary, if multiple functions are connected to form a sentence, the result after processing each function is displayed on arbitrary video screens 10e and 10f. As described above, a user skilled in operating a program can use the button 10a more conveniently than pressing the button 10a and speed up the processing.

An example of the script expression used in the script mode in the script mode area 10b is as follows.

Functionname1 (videoname); Functionname2 (videoname); Function Name 3 (Video Name)

The processing result in "Equation 1" first performs processing corresponding to "function name 3" on the original image, and performs processing corresponding to "function name 2" on the processed result, and then again the processing. After performing the processing corresponding to "Function Name 1" on the result, the final processed result is displayed on the arbitrary video screens 10e and 10f. You can easily achieve the desired result by writing a script without having to press the button 10a for each.

The history of the script expression is displayed in the history area 10d. If the following expression " Equation 2 " is entered and executed, the content is displayed in the order executed before the history area 10d as it is.

Function name 1 (video name 1);

Function name 2 (video name 2);

Function name 3 (video name 3); Function Name 4 (Video Name 4)

Another function of the history area 10d is that if one script expression in the history is selected, the expression is displayed directly in the script mode area 10b so that the same script expression does not need to be entered again.

Meanwhile, a script processing process is displayed in the script mode area 10b so that the user may be familiar with the script mode. When the button 10a or icon 10c corresponding to the image processing is clicked, the script mode area 10b is displayed. In the following, a function corresponding to the processing of the button 10a is displayed in the form of "Equation 3" below in the script mode area 10b.

Function name 3 (video name 3); Function Name 4 (Video Name 4)

Therefore, the user can observe the script expression while pressing the button 10a, and it is easy to learn the form of the script expression, so that it can be utilized when using the script mode or using the library.

The library unit 130 provides a function corresponding to the function of the button 10a, which is composed of unique functions and parameters corresponding to all the buttons 10a present in the GUI screen 10, and forms of the function. Has the same form as the function name in script mode.

In addition, when the library unit 130 is included, a function used in the script mode may be used. When the library unit 130 is brought into a function form and programmed, the same function as that of the button 10a may be performed. For this reason, when the program is developed, only the library unit 130 is included, and the corresponding function can be used as it is, so that a separate program does not need to be produced.

At this time, the function provided by the library unit 130 has the form of "Equation 4" as follows.

Function name (image name, parameter 1, parameter 2,…, parameter n)

The function name of "Equation 4" corresponds to the name of a function to be processed by the user, and the image name to be processed refers to the original image to be processed in "Equation 2". Parameters 1 through n of Equation 4 may be added as necessary depending on the function of the function.

On the other hand, when inputting an image online, when the input button of the button 10a under the GUI screen 10 environment is pressed, the image signal is transmitted from the camera 200, the monitor 300 connected to the image input unit 110 The images are continuously displayed, and when the grab button is pressed in the button 10a, the image at that time is displayed on the GUI screen 10 of the monitor 300 in the form of a still image.

When the button 10a corresponding to various functions provided on the GUI screen 10 is pressed on the image displayed on the GUI screen 10, the above-described functions are performed on the image on the line which has been processed immediately.

3 is a flowchart of a digital image editing method according to the present invention.

In FIG. 3, the user determines whether an image is opened for editing an image on the GUI screen 10 of the computer 100 (step S100), and if the image is not opened, opens the processed image (step S101). When the processed image is opened, one of the following three methods can be selected for inputting the script expression. First, the process button 10a can be selected (step S102) to display the script expression (step S103). That is, as described above, a corresponding image processing algorithm is matched to the processing button 10a, so that a corresponding script expression can be selected.

In addition, the script expression is directly input (step S104). By selecting the desired script expression from the script history (step S105), the script expression can be displayed (step S106). If you directly enter the script expression, it is entered in the script mode area so it is not displayed separately.

If a script expression is input by directly inputting the script expression or selecting a desired script expression from the script history, the suitability of the script expression is determined (step S108). As a result of the determination, if the script expression is not suitable, an error message is displayed (step S109), and the process returns to step S100. At this time, when the processing button 10a is selected and the script expression is displayed, suitability is already determined. No other suitability will be determined.

If the script expression is selected through the processing button or if it is determined that the script expression is suitable, an image processing function is executed (step S110), and an image according to the processing result is displayed (step S111).

If an image is displayed in step S111, the script history is saved (step S112), and it is determined whether or not to terminate (step S113).

FIG. 4 is an embodiment of the GUI screen shown in FIG. 2, FIG. 5 is an embodiment of the script mode area shown in FIG. 2, and FIG. 6 is an embodiment of an enlarged window of the local area shown in FIG. 2. .
