Image size adjustment method

The present invention relates to an image size adjustment method, and more particularly to an image size adjustment method for partial image enlargement.

In recent years, with the rapid development of technology and information, the manufacturing technology of electronic products has also gradually improved. Under the consideration of modern people's pursuit of portability and practicality, electronic products are moving towards light, thin and short features.

In the case of computer devices, from the early days of only desktop computers to the development of notebooks that can be carried around today, notebook computers have been miniaturized from early large-sized notebook computers (screen size of 12 inches or more). A small-sized notebook computer (up to 10 inches in size) that is common in the market. In recent years, modern people have pursued the trend of miniaturization of electronic products, and in recent years, they have developed smaller and thinner tablet computers with smaller notebook computers. Tablet PCs are thin and light, and the input interface of tablet PCs uses touch technology. Furthermore, the tablet computer itself does not have a traditional mechanical keyboard or a mouse, and the tablet computer uses a touch screen as an input interface for the user to operate the tablet computer. Since the size of the screen of the tablet computer is small, the internal software or hard system of the tablet computer has an instruction to enlarge the screen function, so that the user can enlarge the screen and view it conveniently.

However, at present, the screen enlargement function of the tablet type computer means that the zoom display can be simultaneously performed for all the screens. Therefore, when the user wants to view a small portion of the enlarged screen content, the entire enlarged screen must be moved to adjust the enlarged screen of the portion to the position suitable for viewing. Therefore, the current drawing of tablet computers The face enlargement function does not only enlarge the local area, which will cause inconvenience to the user.

Moreover, the computing power of the tablet computer is not as good as that of a notebook computer or a desktop computer, so that only a part of the content needs to be enlarged, and the computing load on the system is relatively increased. As a result, if the tablet is operated to enlarge the screen, the problem of delaying the display of the screen may occur.

The invention provides a method for adjusting the image size, so as to solve the problem that the screen enlargement function of the tablet computer does not only enlarge the local area, which causes the user's inconvenience in viewing and the increase of the system computing load.

The image size adjustment method disclosed in the embodiment includes the following steps: displaying a browsing screen on a screen; receiving an image size adjustment instruction, selecting an image size adjustment coordinate and selecting a size adjustment coordinate; and generating a target range according to the size adjustment coordinate The area and an image size adjustment area are further enlarged and displayed in the image size adjustment area on the browsing screen according to a magnification.

According to the image size adjustment method disclosed in the above embodiment, the user can randomly select a partial area on the browsing screen, and enlarge and display the selected area image in the image size adjustment area. Therefore, the image size adjustment method of the present embodiment can solve the effect that the picture enlargement function of the tablet type computer cannot be enlarged for a local area, thereby providing a user with convenient viewing and a simple operation mode. In addition, the image size adjustment method of the embodiment can reduce the load of the system operation to improve the performance of the computer system.

With regard to the features, implementation and efficacy of this embodiment, it is best to implement the pattern. The details are as follows.

Please refer to "1" and "2" to "5". "1" is a flowchart of the image size adjustment method of the embodiment, "2" and "3". FIG. 4 is a schematic diagram of an image size adjustment command executed in an embodiment, and FIG. 4 is an enlarged view of an object of an embodiment, and FIG. 5 is a schematic diagram of an execution magnification adjustment command according to an embodiment.

The image size adjustment method of the embodiment can be applied to a working system of a desktop computer, a personal computer, or a tablet computer. The drawing of the embodiment is a tablet computer with a touch panel, but This is limited to this.

First, the computer system displays a browsing screen 100 on the touch screen 10 of the tablet computer, and displays an execution icon 102 on the browsing screen 100 (S110), as shown in FIG.

The browsing screen 100 may be a system execution desktop, a webpage or a file software interface, but is not limited thereto. As shown in the diagram of the embodiment, the browsing screen 100 is exemplified by a web page. The execution icon 102 described above may be any pattern, such as a circular block diagram, a magnifying glass pattern, a star pattern, or a rectangular pattern. For the execution icon 102 of the embodiment, the execution icon 102 is a circular block diagram, and the execution icon 102 is located at the upper right corner of the browsing screen 100, but is not limited thereto. In addition, the execution icon 102 may be displayed on the browsing screen 100 at a fixed point, or the execution icon 102 may be embedded in the frame interface of the browser, but is not limited thereto.

When the user wants to browse the target object 110 in a partial area on the screen 100 (譬 When the piano pattern in the figure is enlarged, an image size adjustment instruction is issued to the touch screen 10 of the tablet computer. The operation procedure of the image size adjustment command is that the user touches the execution icon 102 on the browsing screen 100 with the finger 30, and then the user's finger 30 is along an initial position 23' along a first towing path. 21 is displaced to an end position 23, and the finger 30 is pointed at the target 110 as shown in "Fig. 3".

When the finger 30 touches the action of executing the icon 102 and dragging, the computer system receives the signal of the image size adjustment command, and causes the execution icon 102 to be followed by the initial position 23' on the browsing screen 100. The movement of the finger 30 is displaced to the end position 23. And, the computer system starts to calculate a size adjustment coordinate corresponding to the end position 23 (S120).

Next, the computer system removes the execution icon 102 so that the execution icon 102 is not displayed on the browsing screen 100 (S130).

Next, the computer system acquires a target range area 241 according to the size adjustment coordinates and a first preset frame 24 (S140).

The computer system acquires an image size adjustment area 251 according to the size adjustment coordinates and a second preset frame 25 (S150).

The first preset frame 24 and the second preset frame 25 are built in the computer system, and the first preset frame 24 and the second preset frame 25 are respectively a round frame. In this embodiment, the radius of the first preset frame 24 is smaller than the radius of the second preset frame 25, for example, the first preset frame 24 is a circular frame having a radius of 2 cm, and the second preset frame 25 is a A round frame with a radius of 3 cm. The computer system sets the size adjustment coordinates to the centers of the first preset frame 24 and the second preset frame 25 to define the first preset frame 24 respectively. The range of the surrounding area is the target range area 241 described above, and the range surrounded by the second preset frame 25 is the image size adjustment area 251 described above. The shapes of the first preset frame 24 and the second preset frame 25 are not used to define the present invention. In other embodiments, the shapes of the first preset frame 24 and the second preset frame 25 may also be rectangular.

Next, the computer system can enlarge the screen in the target range area 241 according to a predetermined magnification, and display the enlarged screen in the image size adjustment area 251 on the browsing screen 100 (S160). For example, the computer system enlarges the target object 110 (piano pattern in the drawing) in the target range area 241 to a target object 112 that is enlarged by 150% at a magnification of 150%, and displays the target object 112 that is enlarged by 150%. The image size adjustment area 251 is as shown in "Fig. 4". Furthermore, the step of enlarging the image in the target range area 241 according to the preset magnification may further include the following steps: the computer system captures the picture in the target range area 241, and temporarily stores the picture as a picture. The image is enlarged and displayed in the image size adjustment area 251 according to the magnification.

It should be noted that the object 110 of the above embodiment is taken as an example of a piano pattern, but is not limited thereto. For example, when the target object 112 is a simple text, the step of enlarging the image in the target range area 241 according to the preset magnification may further include the following steps: the computer system captures the text in the target range area 241. 110', the font 110' is enlarged and displayed in the image resizing area 251 by adjusting the font size of the text 110' according to the magnification. For example, as shown in "Figure 6" and "Figure 7", the computer system captures the text 110' in the target range area 241 of the webpage, and adjusts the parameters of the text encoding to enlarge the text 110' into the text 112. 'and displayed in the image size adjustment area 251.

In addition, if the target object 112 is an image inclusion character, the step of enlarging the image in the target range area 241 according to the preset magnification may further include the following steps: capturing the image in the target range area 241 And the image is recognized by the character, and the text in the image is enlarged and displayed in the image size adjustment area 251 according to the magnification. For example, as shown in "Figure 8" and "Figure 9", the computer system captures the image 110" in the target range area 241 of the webpage, and performs character recognition on the image 110" to identify the image. Like the text 1101 on 110". Then, the character of the text code is adjusted to enlarge the text 1101" into the text 1121" which is enlarged by 150%, and the text 1121" which is enlarged by 150% is displayed in the image size adjustment area 251. The image 110" can continue to be displayed on the image size. The area 251 is adjusted to become the image 112", that is, the image 112" is the same size as the original image 110". In addition, in another embodiment, only 150% of the image size adjustment area 251 can be displayed. Text 1121" does not display image 112".

In addition, the image size adjustment method of the present embodiment further has a function of adjusting the magnification, and the steps are as follows.

First, the computer system displays a magnification adjustment map 104 on the browsing screen 100. The magnification adjustment map 104 is a ring-shaped outer frame surrounding the image size adjustment area 251 (S170). The magnification adjustment icon 104 has different magnification indications, and the magnification indications may be displayed on the upper, lower, left, and right ends of the magnification adjustment icon 104, but are not limited thereto. Taking "figure 4" of the present embodiment as an example, the upper, lower, left, and right ends of the magnification adjustment map 104 respectively indicate numbers 150, numbers 300, numbers 100, and numbers 200 representing different magnifications. Wherein, the number 100 represents a magnification of 100%, the number 150 represents a magnification of 150%, and the number 200 represents a magnification of 200%. The number 300 represents a magnification of 300%. Also, the number located at the upper end of the magnification adjustment map 104 represents the magnification performed by the current computer system on the screen in the target range area 241. As shown in "Fig. 4", the number at the upper end of the magnification adjustment map 104 is 150, which means that the current computer system performs a magnification of 150% on the screen in the target range area 241. It should be noted that adjusting the number at the upper end of the graph 104 by magnification to represent the magnification of the current computer system is not intended to limit the present invention. For example, the numbers below, left, or right of the icon 104 can also be adjusted to represent the magnification performed by the current computer system.

When the user wants to adjust the magnification, the finger 104 is touched by the finger 30 to adjust the icon 104 and perform the drag operation. The start point and the end point of the finger 30 when the drag operation is performed are all located on the magnification adjustment icon 104 to issue a magnification adjustment command to the computer system. At this time, the computer system receives the signal of the magnification adjustment command, and rotates the magnification adjustment map 104 with respect to the image size adjustment area 251, and simultaneously adjusts the magnification (S180).

For example, when the finger 30 performs the action of the second drag path 22 in the counterclockwise direction on the magnification adjustment icon 104, the magnification adjustment icon 104 is rotated counterclockwise with respect to the image size adjustment area 251, so that the number 200 is marked. Go to the upper end of the magnification adjustment icon 104. At this point, the computer system performs a magnification change that adjusts the magnification from 150% to 200%. In contrast, the image presented in the image size adjustment area 251 is already a target object 114 that is enlarged by 200%. The amount of the angle of rotation of the magnification adjustment icon 104 may depend on the number of drag commands operated by the finger 30. For example, when the finger 30 operates the drag command once, the magnification adjustment icon 104 is rotated by 90 degrees. Alternatively, the amount of angle by which the magnification adjustment icon 104 is rotated depends on the finger 30 The path length of the second drag path 22 when the drag command is operated. For example, when the path length of the second drag path 22 is less than a quarter of the circumference of the magnification adjustment map 104, the magnification adjustment map 104 is rotated by 90 degrees. When the path length of the second drag path 22 is greater than a quarter of the circumference of the magnification adjustment map 104 and less than one-half of the circumference of the magnification adjustment map 104, the magnification adjustment map 104 is rotated by 180 degrees.

Please refer to FIG. 10, which is a schematic diagram of an execution displacement command according to an embodiment. The image size adjustment method of the present embodiment further has a function of adjusting the positions of the target range area and the image size adjustment area, and the method is as follows.

When the user wants to select a target change, the icon 104 is adjusted by the finger 30 touch magnification and the drag operation is performed. The starting point when the finger 30 performs the dragging operation is located on the magnification adjustment icon 104, and the end point of the dragging action is located outside the magnification adjustment icon 104 to issue a displacement command to the computer system. At this time, the computer system receives the signal of the displacement command, and translates the target range area and the image size adjustment area to change the target to be enlarged.

For example, when the finger 30 touches the magnification adjustment icon 104 and performs a third drag path 26 toward the lower left of the browsing screen 100, the end position of the finger 30 is located outside the magnification adjustment icon 104. At this time, the magnification adjustment map 104, the image size adjustment area 251, and the target range area 241 are simultaneously displaced toward the lower left of the browsing screen 100, so that the target object 114 in the target range area 241 is changed from the piano in the center of the browsing screen 100 to the browsing screen. 100 electric guitar in the lower left corner. At this time, the computer system enlarges and displays the electric guitar in the lower left corner of the browsing screen 100 in the image size adjustment area 251 in accordance with the magnification of the piano originally located in the center of the browsing screen 100. By adjusting the target range area 241 and the image size adjustment area 251 described above The function of the position allows the user to arbitrarily change the target to be enlarged.

In addition, when the user wants to end the zoom function performed by the computer system, the user only needs to issue an end command to the computer system. When the computer system receives the end command, the computer system removes the image resizing area 251 from the browsing screen 100, and redisplays the execution icon 102 at the initial position 23' (S190). The end instruction may be a double click instruction. For example, the user can continuously touch the finger 30 to the image resizing area 251 twice to enable the computer system to receive the end command signal. It should be noted that the end instruction is not limited to the above double-click instruction, and the end instruction is also a one-click instruction or a three-click instruction, but is not limited thereto.

According to the image size adjustment method disclosed in the above embodiment, an execution icon is displayed on the browsing screen to facilitate the user to intuitively operate the instruction for releasing the image enlargement function. In addition, the image size adjustment method in this embodiment allows the user to randomly select a partial area on the browsing screen for zooming in to facilitate viewing by the user. Moreover, the image size adjustment method of the embodiment further provides a function for the user to adjust the magnification to meet the needs of the user. In addition, since the image size adjustment method of the present embodiment only amplifies the partial image, the amount of computational processing required by the computer system is relatively small. As a result, the load on the system operation can be reduced to improve the performance of the computer system.

While the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention.
