The screen capture device 100 includes a screenshot module 101, an image encoding module 102, an image enlargement module 103, and a positioning pointer module 104. The screenshot module 101 is configured to receive a screenshot request, capture screen image information, save location information of the anchor point, and a screenshot selected by the user. The image encoding module 102 is configured to encode the data transmitted by the screenshot module 101. The image enlargement module 103 displays the screenshot window on the computer screen based on the data transmitted by the image encoding module 102. The positioning pointer module 104 displays the positioning pointer in the screenshot window based on the data transmitted by the image encoding module 102.

2 is a flow chart of a screen shot method in an embodiment of the present invention. The screen capture method includes the following steps (at this time, the instant messaging system is turned on):

Sl, receive a screenshot request.

This step is implemented by the screenshot module 101. After receiving the screenshot request, the screenshot module 101 turns on the screenshot function. 52. Capture image information to be enlarged and mouse pointer position information.

This step is implemented by the screenshot module 101. Specifically, first, the position information at the mouse pointer is obtained by the position information returned by the related driving device. Secondly, the color of the pixel around the mouse pointer and the corresponding position information are obtained according to a preset zooming range (eg, 200*200), wherein the mouse pointer The color of the surrounding pixels is obtained by the RGB value of each pixel, and when the position of the pixel around the mouse pointer exceeds the preset magnification range, the color of its pixel is not acquired. The screenshot module 101 captures the color, position information (i.e., image information to be enlarged) of the pixels around the mouse pointer and the mouse pointer on the computer screen, and the mouse pointer position information, and transmits the captured information to the image encoding module 102.

53. Encode the enlarged image information and the mouse pointer position information.

This step is implemented by image encoding module 102. The image encoding module 102 performs encoding processing on the received information, and then transmits the encoded data to the image amplifying module 103 and the positioning pointer module 104, wherein the image is encoded by a common image encoding technique for network transmission.

54. Display the screenshot window and the positioning pointer.

This step is implemented by the image magnification module 103 and the positioning pointer module 104. The image enlargement module 103 displays the encoded data through a computer screen, that is, a screenshot window appears on the computer screen. Figure 3 is a schematic diagram of the screenshot window. 300 denotes a computer screen, and 301 denotes a screenshot window. The screenshot window 301 includes a help information window 302, an anchor point information window 303, and an image enlargement window 304. The help information window 302 displays help information related to the screenshot operation. The image enlargement window 304 displays a magnified image of the image around the mouse pointer and around the mouse pointer.

The positioning pointer module 104 displays the encoded data through the screenshot window 301, that is, a cross-shaped pointer 305 appears in the image enlargement window 304, and the intersection point of the cross-shaped pointer 305 is the positioning point, and the positioning is displayed in the positioning point information window 303. The color and coordinate information of the pixel at the point, the size of the screenshot, and other information. It should be noted that the shape of the pointer may be a cross shape, or may be other shapes, such as an arrow shape. Any pointer shape capable of positioning and identifying an image belongs to the needle of the present invention as an example.

55. Determine whether the position of the mouse pointer changes. If yes, execute S2; if not, execute

S6.

This step is implemented by the screenshot module 101. The screenshot module 101 captures the position information of the mouse pointer in real time and compares it with the previously stored mouse pointer position information. If they are the same, it means that the position of the mouse pointer has not changed; if it is different, it means that the position of the mouse pointer has changed. When the position of the mouse pointer changes, steps S2 to S4 are immediately repeated, that is, the content of the screenshot window 301 is updated in real time.

56. Receive and save the first positioning point request.

You can use the circular, elliptical or rectangular frame selection tool to select the screen image to be saved. Now, the most commonly used rectangular frame selection tool is used as an example. Figure 4 is a schematic diagram of selecting a screen image using a rectangular frame selection tool. When the screen image is selected by using the rectangular frame selection tool, only the position of the first positioning point 401 and the second positioning point 402 on the diagonal line needs to be determined to determine the size of the rectangle 403. That is, the user only needs to accurately determine the size. The position of an anchor point 401 and the second anchor point 402 can accurately determine the screen image to be saved.

When the user selects the first anchor point 401 (for example, clicking the left mouse button), the screenshot module 101 receives the save first location request and then saves the location information of the first anchor point 401.

S7: Receive and save the second anchor point request.

After the user selects the second anchor point 402 (for example, clicking the left mouse button), the screenshot module 101 receives the save second location point request, and then saves the location information of the second anchor point 402. S8: Save the screenshot.

The screenshot module 101 determines the range of the screenshot selected by the user according to the positions of the first and second anchor points 402, and then saves the screenshot selected by the user.

The screen capture device 100 in the embodiment of the present invention uses the image enlargement module 103 and the positioning pointer module 104 to display an enlarged image of the mouse pointer and the mouse pointer, and convert the mouse pointer into a positioning pointer to display in the enlarged image. When the user performs a screenshot operation, the position of the anchor point can be determined very accurately, so that the error of the screenshot can be controlled at the level of the pixel. In other words, the screenshot method can be used to capture the screen image very accurately.
