Electronic device and method for magnifying and displaying partial screen content thereof

Abstract

An electronic device and a method for magnifying and displaying partial screen content thereof. A cursor position is obtained within the display area of ​​a monitor. A screen boundary region within the display area is determined based on the radius of a magnified display area and the monitor's screen resolution. A window position of a transparent window is determined based on whether the cursor position is located within the screen boundary region. This transparent window is a display container for presenting the magnified display area, and the magnified display area is centered within the transparent window. Based on the cursor position, magnified image content of the magnified display area is obtained from an original display frame. Based on the window position of the transparent window, a composite display frame including the magnified image content is displayed on the monitor.

Claims

1. A method for magnifying the display of partial screen content, applicable to electronic devices including a display, and comprising: Obtain the position of a cursor within the display area of ​​the monitor; Based on the radius of a magnified display block and the screen resolution of the display, a screen boundary region within the display area is determined; based on whether the cursor position is located within the screen boundary region, the window position of a transparent window is determined, wherein the transparent window is a display container for presenting the magnified display block, and the magnified display block is centered within the transparent window; based on the cursor position, the magnified image content of the magnified display block is obtained from an original display frame; and based on the window position of the transparent window, a composite display frame including the magnified image content is displayed through the display.

2. The method for magnifying and displaying partial screen content as described in claim 1, wherein the step of determining the screen boundary region within the screen display range based on the radius distance of the magnified display area and the screen resolution of the display includes: Based on the width of the magnified display area and the horizontal resolution of the display, the left and right boundary positions of the screen boundary area along the horizontal axis are determined; and based on the height of the magnified display area and the vertical resolution of the display, the upper and lower boundary positions of the screen boundary area along the vertical axis are determined.

3. The method for magnifying and displaying partial screen content as described in claim 1, wherein the step of determining the window position of the transparent window based on whether the cursor position is located in the screen boundary region includes: When the cursor position is not within the screen boundary area, the window position of the transparent window is determined according to the cursor position and the window size of the transparent window, so that the center of the transparent window corresponds to the cursor position.

4. The method for magnifying and displaying partial screen content as described in claim 1, wherein the step of determining the window position of the transparent window based on whether the cursor position is located in the screen boundary region includes: When the cursor position is within the screen boundary area, the window position of the transparent window is determined according to the distance between the cursor position and the radius of the magnified display block, so that the magnified display block is within the screen display range.

5. The method for magnifying and displaying partial screen content as described in claim 1, wherein the step of obtaining the magnified image content of the magnified display block from the original display frame according to the cursor position includes: Based on the distance between the cursor position and the radius of the magnified display block, the magnified image content of the magnified display block is obtained from the original display frame.

6. The method for magnifying and displaying partial screen content as described in claim 5, wherein the step of obtaining the magnified image content of the magnified display block from the original display frame based on the radius distance between the cursor position and the magnified display block includes: An image alignment ratio is determined based on the cursor position, the radius distance of the magnified display area, and the screen resolution. And the magnified image content of the magnified display block is obtained from the original display frame through a rendering component according to the image alignment ratio.

7. The method for magnifying and displaying partial screen content as described in claim 6, wherein the image alignment ratio includes a first image alignment ratio along the horizontal axis and a second image alignment ratio along the vertical axis.

8. The method for magnifying and displaying partial screen content as described in claim 1, further comprising: When a size scaling message is received to adjust the radius distance of the magnified display block, the radius distance of the magnified display block is adjusted to obtain the original block position of the magnified display block; and the original block position of the magnified display block is corrected to a new block position according to the cursor position and the radius distance scaling amount.

9. The method for magnifying a portion of screen content as described in claim 8, wherein the step of correcting the original block position of the magnified display area to the new block position based on the cursor position and the radius distance scaling amount includes: When the size scaling message is a size enlargement message, the new block position is obtained by subtracting the radius distance magnification amount from the original block position; And when the size scaling message is a size reduction message, the new block position is obtained by adding the radius distance reduction amount to the original block position.

10. The method for magnifying partial screen content as described in claim 1, wherein the window properties of the transparent window are configured by a user instruction.

11. An electronic device comprising: One monitor; The system includes at least one processor coupled to the display and configured to: acquire a cursor position within the display area of ​​the display; determine a screen boundary region within the display area based on the radius of a magnified display block and the screen resolution of the display; determine a window position of a transparent window based on whether the cursor position is located within the screen boundary region, wherein the transparent window is used to present a display container of the magnified display block, and the magnified display block is centered within the transparent window; acquire magnified image content of the magnified display block from an original display frame based on the cursor position; and display a composite display frame including the magnified image content through the display based on the window position of the transparent window.
