Description

Line input based image processing method and apparatus therefor {Method and Apparatus Processing Image Based on the First Inputted Command}

The present invention relates to a line input based image processing method and a device thereof, and more particularly, to a multi-touch device and a method of realizing a function of a multi-touch pad using a single touch device.

In a pointing device that designates a coordinate system of a display, such as a mouse, a touch pad, and a touch panel, it is possible to track only a single coordinate at a specific point in time.

That is, when a user clicks or drags a graphical user interface (GUI) on the device display, one coordinate value or a set of one coordinates is generated. Therefore, it was not possible to apply an application through tracking two or more coordinates at the same time or a multi-touch method that can perform various functions. In order to make up for the drawbacks of the touch screen, there is a scrolling application in which a drag event is changed to a scroll event by dividing an area of the touch pad, but a limitation thereof is clearly present.

In order to implement the multi-touch technology, which is an issue recently, not only software for recognizing multiple simultaneous touch points, but also a hardware element such as a multi-touch screen or a multi-touch pad is required. Multi-touch technology is achieved by various means such as heat, pressure of user's finger input, camera with high capture ratio, infrared ray, optical capture, etc. There is a problem in that a hardware element is required, and a weight increase due to the addition of a touch layer for sensing multi-touch, and a dedicated stylus pen for improving sharpness are used.

Accordingly, the present invention is to solve the above problems according to the prior art, a line input for implementing a multi-touch method by selecting the image editing mode through the user's pre-input command, calculate the additional gesture input of the user for this It is an object of the present invention to provide a method and a device based image processing.

According to an aspect of the present invention, a line input based image processing method includes selecting an image editing mode by analyzing a touch trace on a touch screen and setting the touch trace as a reference coordinate, after selecting the image editing mode, the line input based image The processing device may include editing the original video according to the video editing gesture received from the user.

In this case, the selecting of the image editing mode may include selecting a two-dimensional image editing mode when the touch trace on the touch screen is a single coordinate, and selecting a three-dimensional image editing mode when the touch trace on the touch screen is a touch trace. Can be.

The setting of the touch trajectory as the reference coordinate may include setting the single point as the reference coordinate of the two-dimensional image editing mode when the touch trajectory on the touch screen is the single point.

When the two-dimensional image editing mode is selected, the step of editing the original image according to the image editing gesture received from the user may be a direction in which both absolute values of the X and Y coordinates are increased from the user, or the absolute value of the X coordinate is increased. The absolute value of the Y coordinate is in the direction of maintaining 0, or on the contrary, receiving an image editing gesture in a direction in which the absolute value of the X coordinate is 0 and the absolute value of the Y coordinate is increased and the original image based on the reference coordinate. May be enlarged and edited at a predetermined ratio.

In addition, when the two-dimensional image editing mode is selected, the step of editing the original image according to the image editing gesture received from the user is the direction in which the absolute values of the X and Y coordinates all decrease or the absolute value of the X coordinates decreases. And receiving an image editing gesture in a direction in which the absolute value of the Y coordinate is 0 or the direction in which the absolute value of the X coordinate is 0 and the absolute value of the Y coordinate is decreased. The method may include reducing and editing the original image at a predetermined ratio based on the reference coordinates.

Furthermore, when the two-dimensional image editing mode is selected, editing the original image according to the image editing gesture received from the user may include receiving an image editing gesture in the form of an arc from the user, and the line input based image processing apparatus may use the reference coordinates. It may include a step of rotating and editing the original image around the.

In the setting of the touch trajectory as a reference coordinate, a straight line approximating the input touch trajectory on the touch screen is selected to select a 3D image editing mode, and the straight line is parallel to the vertical direction of the touch screen to contact the original image. The moved straight line may be set as a reference line in the 3D image editing mode.

In this case, when the three-dimensional image editing mode is selected, the step of editing the original image according to the image editing gesture received from the user is the step of receiving an image editing gesture in the form of an arc from the user, the object of the three-dimensional original image around the reference line Rotating editing may include.

The rotation editing process of the original image may be characterized in that the direction of rotation editing the original image is determined according to the direction of the image editing gesture arc input from the user.

In addition, the rotation editing process of the original image may be performed by receiving an input angle for rotating the original image from the user, and may rotate the original image by the input rotation angle.

The line input based image processing apparatus according to another aspect of the present invention selects an image editing mode by analyzing a touch screen for receiving a touch trace from a user and a touch trace input on the touch screen, and sets the touch trace as a reference coordinate. On the other hand, it includes a central processing unit for editing the original image according to the image editing gesture received from the user.

In this case, the CPU may select a two-dimensional image editing mode when the touch trajectory on the touch screen is a single coordinate, and select a three-dimensional image editing mode when the touch trajectory on the touch screen is a touch trajectory.

The CPU may set the single point as a reference coordinate of a two-dimensional image editing mode when the touch trace on the touch screen is a single point.

In this case, the central processing unit is a direction in which the absolute values of the X and Y coordinates all increase from the user, or the absolute value of the X coordinate is increased and the absolute value of the Y coordinate is 0 or the absolute value of the X coordinate. In the case where the image editing gesture is maintained in the direction in which the absolute value of the Y coordinate is increased while maintaining the zero, the original image may be enlarged and edited at a predetermined ratio around the reference coordinate.

In addition, the CPU may be a direction in which the absolute values of the X and Y coordinates are all decreased from the user, or the absolute value of the X coordinate is decreased and the absolute value of the Y coordinate is 0 or the absolute value of the X coordinate is conversely. In the case where the image editing gesture in the direction in which the absolute value of the Y coordinate is decreased while maintaining this 0 is received, the original image may be reduced and edited at a predetermined ratio based on the reference coordinate.

Further, when the central processing apparatus receives an image editing gesture in the form of an arc from a user, the CPU may rotate and edit the original image based on the reference coordinate.

Meanwhile, the CPU may obtain a straight line approximating the input touch trajectory on the touch screen, and set a straight line in which the straight line is moved in parallel in the vertical direction of the touch screen to contact the original image as a reference line in the 3D image editing mode. . In this case, the CPU receives an arc-shaped image editing gesture from the user, and accordingly rotates and edits an object of a 3D original image based on the reference line.

As described above, since the line input-based image processing method and apparatus according to the present invention implement the multi-touch method through a command input by a user first, there is no need to provide a separate hardware device for the multi-touch function. Applicable to a touch panel or a touch pad-based device that can track only a single pointing coordinate at a specific time point.

In addition, the line input-based image processing method and apparatus according to the present invention and the mobile phone, PDA (Personal Digital Assistants), smart phones that require multi-touch in addition to the embodiment for the operation of two-dimensional or three-dimensional image on the display of the touch panel and It can be used in various applications such as mobile devices or touch panel based embedded systems.

Hereinafter, a line input based image processing apparatus and a method thereof according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a line input based multi-touch method according to an embodiment of the present invention.

The pre-input based image processing apparatus according to the present invention first receives a source image to be edited (S101). The pre-input-based image processing apparatus may output the input original image to the display so that the user can check it.

After checking the original image output on the display, the user inputs a touch for selecting an image editing mode on a touch screen connected to the line input based image processing apparatus, and the line input based image processing apparatus detects this (S102). . The image editing mode selectable in step S102 includes a 2D image editing mode and a 3D image editing mode. This will be discussed in more detail later.

The line input based image processing apparatus stores coordinate values touched by the user on the touch screen, and analyzes the stored coordinates to select an image mode (S103). The line input based image processing apparatus determines whether the touched form is a single point form or a line form based on the analysis result of S103 (S104).

If the touch input type is a single point type, the line input based image processing apparatus performs a 2D image editing mode, and sets the coordinates of the single point as reference coordinates for 2D image editing.

Meanwhile, when the touch input form is in the form of a line, the line input based image processing apparatus performs a 3D image editing mode and sets the input line as a reference axis for 3D image editing. In this case, the input line may be a curve. In this case, a straight line corresponding to the curve trajectory is calculated and a reference axis is generated using the straight line. The generation of the reference axis will be described in detail with reference to FIG. 7.

In the process of S105 and S107, each of the line input-based image processing apparatus enters the image editing mode. The line input based image processing apparatus receives a touch for image editing from a user in each mode (S106 and S108). The touch for editing the image is referred to as a gesture.

The pre-input based image processing apparatus performs the original image editing indicated by the current image editing mode and the gesture input according to the present image editing mode (S109). The line input based image processing apparatus outputs the edited result image to the display (S110).

Hereinafter, an example of editing an original image supported by a pre-input-based image processing apparatus according to an image editing value from a user will be described in more detail.

2 is a diagram illustrating a gesture input for two-dimensional enlargement and reduction editing of an original image according to the present invention.

In FIG. 2A, the user first touches the (X0, Y0) coordinates of the touch screen, and then drags the coordinates to the (Xn, Yn) coordinates via the coordinates of (X1, Y1), (X2, Y2), and the like. One action, or gesture, is shown.

Analyzing the coordinate change shown in FIG. 2A, it can be seen that the user drags in a direction in which both absolute values of the X coordinate and the Y coordinate increase. When the user drags in this manner, the line input based image processing apparatus according to the present invention may perform editing to enlarge the original object two-dimensionally.

In detail, the line input based image processing apparatus stores the input touch coordinates, and | Xn | -| Xn-1 | > 0, | Yn | -| Yn-1 | > 0 or | Xn | -| Xn-1 | > 0, | Yn | -| Yn-1 | = 0 or | Xn | -| Xn-1 | = 0, | Yn | -| Yn-1 | Determine whether the condition of> 0 is satisfied to see if an original target enlargement editing command is input. If the two equations are satisfied, the line input-based image processing apparatus enlarges the current original image two-dimensionally.

FIG. 2B also illustrates a case where the user first touches the (X0, Y0) coordinates of the touch screen and then drags the coordinates through the (X1, Y1), (X2, Y2) coordinates, and the like to the (Xn, Yn) coordinates. Indicates the operation of.

Analyzing the coordinates illustrated in FIG. 2B, it can be seen that the user drags in a direction in which both absolute values of the X coordinate and the Y coordinate decrease. When the user inputs a gesture in this form, the line input based image processing apparatus according to the present invention may perform two-dimensional editing to reduce the original object.

As shown in FIG. 2B, the line input based image processing apparatus stores the input touch coordinates, and | Xn | -| Xn-1 | <0, | Yn | -| Yn-1 | <0 or | Xn | -| Xn-1 | <0, | Yn | -| Yn-1 | = 0 or | Xn | -| Xn-1 | = 0, | Yn | -| Yn-1 | If the condition of <0 is satisfied, editing is performed to reduce the original object two-dimensionally, and as a result, an image is displayed.

3 is a diagram illustrating an example of a 2D enlargement editing method according to the gesture of FIG. 2.

3A illustrates a state in which a touch operation for expanding an image according to FIG. 2A is performed.

As shown in (A) image of FIG. 3, the user selects a 2D image editing mode by taking a dot (a). In this way, the point touched to select the image editing mode (a) becomes the reference coordinate for editing the original image.

After selecting the 2D image editing mode, the user may know that the user inputs a drag, i.e., a gesture according to the trajectory (b). (B) Analyzing the gesture, it can be seen that the drag along the trajectory (b) is made in a direction in which both the X and Y coordinates increase from the drag start point.

As a result, as shown in the image (B) of FIG. 3, the line input-based image processing apparatus enlarges the side view of the vehicle, which is the original image, at a predetermined ratio by two dimensions. In this case, the reference coordinate for enlarging the original image is a point (a) entered to select a 2D image editing mode.

4 is a diagram illustrating an example of a 2D reduction editing method according to the gesture of FIG. 2.

4A illustrates a method of performing a touch operation for reducing an image according to FIG. 2B.

As shown in FIG. 4A, the user selects a 2D image editing mode by taking a dot (C). Similarly, the point touched to select the 2D image editing mode (c) becomes a reference coordinate for editing the original image.

After performing the 2D image editing mode, the user inputs a drag and a gesture according to the trajectory (d). (D) Analyzing the gesture, it can be seen that the drag along the trajectory (D) is made in a direction in which both the X and Y coordinates decrease from the drag start point.

As a result, as shown in FIG. 4B, the line input-based image processing apparatus reduces two-dimensionally the car image, which is the original image, by a predetermined ratio. Of course, as in FIG. 3, the reference coordinate for the 2D reduction editing is a point (c).

5 is a diagram illustrating an example of a two-dimensional rotation editing method according to the present invention.

Looking at Figure 5 (A) it can be seen that the gesture of the point (e) and (bar) exist. Here, the point (e) corresponds to a single point input by the user in order to set the 2D image editing mode in step S102 of FIG. 1. Meanwhile, the gesture (bar) is a gesture for image editing in step S106 of FIG. 1 and corresponds to a gesture for commanding two-dimensional rotation editing of the original image.

When analyzing the shape of the (bar) gesture or (bar) touch trajectory, the user touches the (X0, Y0) coordinates of the touch screen, and then (X1, Y1), (X2, Y2), and the like (Xn, It can be seen that a semi-circular touch trajectory is input by dragging to Yn).

Analyzing the trajectory (bar) of Figure 5 it can be seen that the X coordinate and Y coordinate does not have a constant direction. However, the trajectory (bar) corresponds to the case having the characteristic of the arc shape in the clockwise direction. The line input based image processing apparatus performs editing to rotate the original object clockwise in response to the input of the trajectory (bar).

FIG. 5B corresponds to a resultant image in which the original image of FIG. 5A is rotated 180 degrees. At this time, the center point of the 180 degree rotation is a single point input for setting a point (e), that is, a 2D image editing mode.

In summary, the line input based image processing apparatus performs editing that rotates the original image currently input according to the gesture input in the clockwise direction about the input point to select the image editing mode.

Here, the following methods exist as a way of adjusting the angle at which the original image is rotated. First, when a gesture of (bar) is uniformly input, there is a method of rotating the original image 90 degrees clockwise. Furthermore, a method of adjusting the rotation angle according to the length of the trajectory (bar) may be considered. In addition, a method of receiving a rotation angle value separately from the user may be considered in order to set a more accurate rotation angle. The line input based image processing apparatus according to the present invention may adjust the rotation angle by selecting at least one of the above methods.

Meanwhile, in FIG. 5, the operation of rotating in the clockwise direction has been described. However, the operation of rotating the original image counterclockwise can be similarly implemented. That is, the line input-based image processing apparatus stores the input touch coordinates and determines whether the line input-based image processing apparatus has an anticlockwise arc shape. When such a condition is satisfied, the pre-input-based image processing apparatus performs editing to rotate the original image currently input counterclockwise. Of course, the coordinate that is the center of rotation is also a single point input to select the image editing mode as point (e).

6 is a diagram illustrating a touch form for selecting a 3D image editing mode of an original image according to the present invention.

FIG. 6 (A) shows a three-dimensional image made up of an original image in step S101 of FIG. 1. In the state in which FIG. 6A is displayed, the line input-based image processing apparatus receives a touch for selecting an image editing mode from a user.

FIG. 6B illustrates a case in which a user's touch type input in step S102 of FIG. 1 is linear rather than a single coordinate.

As shown in FIG. 6B, the line input based image processing apparatus analyzes an input line trajectory for selecting an image editing mode. If the input line trajectory is a straight line, the trajectory of the input line is set as the reference axis. If the input line trajectory is not an exact straight line, a specific straight line corresponding to an approximation of the coordinate trajectory is calculated. The straight line calculated as described above is used as a reference axis of the 3D image editing mode through the parallel moving process of FIG. 7.

7 is a diagram illustrating parallel movement of a reference axis of a 3D image editing mode of an original image according to the present invention.

First, an orthogonal axis constituting three dimensions of the line input based image processing apparatus will be described. First, as described above, the X and Y axes correspond to orthogonal axes that form a screen of the line input based image processing apparatus. In other words, the width of the screen is regarded as the X axis, and the length of the screen is regarded as the Y axis.

In order to edit a 3D image, a Z axis is required. The line input based image processing apparatus according to the present invention forms a right angle with the screen, and considers the direction toward the user of the image processing apparatus as a positive Z axis. . Based on the above X, Y, and Z axes, the parallel movement of the reference axis will be described.

As illustrated in FIG. 6B, the line input based image processing apparatus has calculated a specific straight line corresponding to an approximation of a straight line or a coordinate trajectory input from a user. FIG. 7A shows a straight line calculated by the line input-based image processing device together with the input 3D image.

The calculated Z coordinate of the straight line is considered to have the largest value Zmax among the Z coordinates of the three-dimensional space set by the line input based image processing apparatus. The line input based image processing apparatus moves the calculated straight line in parallel in the negative Z axis direction from Zmax.

The parallel movement in the Z-axis direction is made up to the point of first contact with the object existing in the original image on the display of the touch panel. The Z coordinate of this point is defined as Ztan.

As such, a straight line according to the result of the parallel movement becomes a reference line for 3D image editing. That is, the reference line for the 3D image editing is specified by the relationship between Y = aX + B (where a and b are arbitrary real numbers) and Z = Ztan by a touch input from the user.

8 is a diagram illustrating a rotation editing method of a 3D image of an original image according to the present invention.

As shown in FIG. 8A, the line input based image processing apparatus receives a gesture input of drawing an arc in a clockwise direction from a user.

The line input-based image processing apparatus that receives the gesture input performs an edit that rotates the original image clockwise based on the reference axis specified in FIG. 7.

That is, among the objects of the image displayed on the touch panel, an object first contacted with the reference axis parallel to the Z axis rotates in a three-dimensional space in a clockwise direction with respect to the reference axis.

In relation to the 3D image rotation editing, the above-described 2D image rotation editing methods may be applied to the method of adjusting the angle at which the original image is rotated. For example, there is a method of uniformly rotating the original image 90 degrees clockwise. In addition, a method of adjusting the rotation angle according to the length of the input trajectory may be considered. In addition, there is a method of receiving a rotation angle value separately from the user so that a more accurate rotation angle can be set.

Of course, as described above, the operation of rotating the original image counterclockwise may be similarly implemented.
