Description

Display method, device and terminal

The present invention relates to the field of digital display, and in particular, to a display method, device and terminal. Background technique

Currently, electronic products with processors and display screens are widely used, such as mobile phones, fixed stations, MP4 (Moving Picture Expert Group 4), PDA (Personal Digital Assistant), digital television, and the like. Among them, the display screens of the above electronic products basically adopt LCD (Liquid Crystal Display), and the LCD display screen is formed by liquid crystal dot matrix, and can not perform various transformations on the content displayed through the LCD display screen according to user needs. For example, when the display content is text data, it can only be displayed according to the fonts already existing in the operating system of the electronic product. At present, most operating systems only save a limited number of font types, and one on the display screen. When the size of a font is changed to another font size, it is actually switching the configuration of one font type to the configuration of another font type.

Taking mobile phones as an example, mobile phones have become a full-featured handheld platform that not only can talk, but also has the functions of sending and receiving emails, scheduling, and shooting, transferring photos, games, storage, music playback and web browsing. Display related content on the phone screen. Referring to FIG. 1, a mobile phone display method is provided, and the display method steps include:

Step 101: Draw the controls in the display screen.

Among them, the control can be picture, color, font and text size.

Step 102: Determine whether the control is activated to another set of control configurations. If yes, go to step 103; otherwise, go to step 104.

Step 104: Use the original control configuration.

Step 105: Draw a control that determines the configuration type to the screen.

In the process of implementing the present invention, the inventors have found that the above display method has at least the following problems:

In the case of electronic products seeking higher and higher screen resolution, the screen can display more and more lines, so the displayed font or picture is relatively small, especially when there are both pictures and text content in the display content. Only the same algorithm can be used to enlarge the text and the picture, which results in poor amplification, which brings inconvenience to the visually impaired person. At the same time, the single configuration conversion can not meet the individualized pursuit of people. . Summary of the invention

The embodiment of the present invention can automatically satisfy the needs of the user's individual pursuit by automatically determining different display effects according to the type of the display content, enrich the display effect, and enhance the practicability of the display device.

Example 1

An embodiment of the present invention provides a display method, including: receiving a transformation request of a user, storing the display content in a corresponding storage area; acquiring a transformation region according to a location where the cursor is transformed; determining a data type in the transformation region, and obtaining the data type according to the data type Corresponding transformation algorithm; transforming data corresponding to the transformation region according to the transformation algorithm to obtain new data; displaying new data.

2 is a schematic flowchart of a display method according to an embodiment of the present invention. This embodiment is described by taking an enlargement operation on a content of a mobile phone display screen as an example:

First you need to create a memory area based on the display screen size and resolution. The details are as follows: Wherein, according to the size of the display screen, a corresponding memory area is established, and the memory area may be greater than or equal to the size of the display screen. Think of a memory region as an array of xX y, and each array element holds information for one pixel. You can also use the virtual network for the resolution of the screen. The form of the grid indicates that the spacing of certain pixels is determined according to the size of the display screen and its display resolution. If the display screen is large, a large spacing is used, and if the display screen resolution is high, a small spacing is used. A virtual grid is a representation of a data structure that does not reflect any information about the grid on the display screen, but various methods can be used to represent the grid. For example, a two-dimensional array of structures can be used to represent a virtual grid. The dimension of the array represents the number of grid points, and the position information of the corresponding grid points is recorded in the structure.

After the memory area is established, when the mobile phone user enables the zoom function, that is, the user issues a request to perform the conversion, perform the following steps:

Step 201: Store different types of display contents in the corresponding storage areas according to the data type of the displayed content in the display screen.

The picture data and the text data of the display content are respectively stored in the corresponding memory areas. For example, you can store image data in the memory area mPic and store the text data in the memory area mTxt.

Step 202: Acquire a transformed region to be enlarged according to where the cursor is located.

The user inserts the transformation cursor into the corresponding position on the display screen, and the transformation cursor may be a cursor specifying a pixel point, or a cursor for selecting an area, and if it is a cursor of the selected area, the cursor is selected. The center serves as a central point. The position of the change cursor is taken as the center point, and the area to be enlarged is determined according to the needs. The size of the area may be determined by the default setting of the system, or may be set according to the user setting function provided by the user, and the shape of the area may be any closed curve ( Or a straight line), wherein the embodiment of the present invention takes the rectangular region which is the easiest to implement as an example, and according to the position where the cursor is currently changed, the coordinate position of the corresponding virtual memory region is pM _a g( _X , y), the system sets a range of 50 pixel pitch sizes around the transformed coordinate pMag(x, y) as an enlarged transform region, thereby obtaining an enlarged transform region rcMag.

Step 203: Determine the data type in the obtained enlarged conversion area. If it is image data, for example, jpg format data, perform step 204; if it is text data, for example, txt format data, execute step 206, if yes When both the picture data and the text data exist, step 208 is performed.

Step 204: Perform polar coordinate conversion operation on the picture data corresponding to the enlarged conversion area in the memory area, and obtain the converted new picture data.

Among them, the polar coordinate transformation operation is an operation in which the transformation center (the position where the cursor is located) is centered, and other grid points are transformed along the method of connecting with the center of the circle. For example, the picture data in the memory area mPic corresponding to the enlarged conversion area rcMag is converted by the polar coordinate method, and the magnification set by the system is 2, and the magnification is doubled.

Step 205: Display the new picture data after the polar coordinate conversion operation to the display screen.

Step 206: Perform xy coordinate conversion operation on the character data corresponding to the enlarged conversion area in the memory area to obtain the converted new character data. The xy coordinate mode conversion operation is an operation of selecting a distance in which only the mesh point is separated from the row direction or the column direction of the transform center, or the distance between the row direction and the column direction is simultaneously converted. For example, the character data in the memory area mTxt corresponding to the enlarged area rcMag is subjected to an xy coordinate method conversion operation, and the distance between the row direction and the column direction is selected and converted, and the magnification set by the system is 1.5, and 1.5 times magnification is performed.

Step 207: Display the new text data after the x-y coordinate conversion operation to the display screen.

Step 208: Convert the picture data and the character data corresponding to the enlarged conversion area in the memory area to the polar coordinate and the x-y coordinate mode, respectively, to obtain the converted new picture data and the new character data.

Step 209: Superimpose and convert the new image data and the new text data into the display screen.

The new picture data and the new text data after the transformation operation are superimposed according to the coordinates of the virtual grid according to the coordinates of the virtual grid, and are superimposed and displayed on the display screen of the mobile phone.

The above-described transform operation method is not limited to the x-y coordinate system transform operation and the polar coordinate method transform operation, and other applicable transform operations may be selected to convert the data types such as characters and pictures in the display content according to the specific conversion needs.

For the method provided by the embodiment of the present invention, referring to FIG. 3, it is a data flow diagram of a display method when a data type of a picture and a text exists in a mobile phone conversion area according to an embodiment of the present invention. As shown in FIG. 3, the enlarged conversion area selected in the display screen of the mobile phone is rcMag, and the image data and the text data exist in the conversion area; in the picture memory area mPic, the part corresponding to the enlarged conversion area is rcMagA, in the text In the memory area mTxt, the part corresponding to the enlarged area is rcMagB; the rcMagA and rcMagB are respectively subjected to enlargement and transformation operations, wherein the picture data is enlarged and transformed by the polar coordinate method, and the character data is enlarged by the xy coordinate method. , respectively, the new image data rcMagAl and the new text data rcMagBl after the transformation operation are obtained; the new image data rcMagAl and the new text data rcMagBl are superimposed according to the coordinate position of the grid point, and the enlarged data content rcMagl is obtained. And displayed in the phone display.

Further, the transform algorithm provided by the embodiment of the present invention is not limited to the two algorithm forms of the enlargement algorithm and the reduction algorithm, and may also select a special effect algorithm to perform transformation according to a user's needs, for example, a fisheye algorithm, a sector algorithm, and the like.
