Abstract
In an image processing method, a server obtains an image sent by a terminal over a network connection. The server splits the image into a plurality of subimages, and converts the subimages into corresponding USB request blocks (URBs). The USB request blocks are received by a USB device driver of the server. The USB device driver splices the URBs back into the image. A USB application program of the server then obtains the image from the USB device driver.
Claims18
An image processing method performed by a server, comprising:
- obtaining, by executing first instructions, an image sent by a terminal over a network connection;
- splitting, by executing the first instructions, the image into a plurality of subimages;
- converting, by executing the first instructions, each subimage in the plurality of subimages into a USB request block (URB);
- splicing, by executing second instructions corresponding to a USB device driver, the URBs converted from the subimages back into the image;
- and
- obtaining, by executing third instructions corresponding to a USB application program, the image from the USB device driver.
3 more elements
An image processing server, comprising:
- a memory storing executable instructions;
- a processor configured to execute first instructions of the executable instructions to:
- obtain an image sent by a terminal over a network connection;
- split the image into a plurality of subimages;
- convert each subimage of the plurality of subimages into a URB;
- the processor being further configured to executed second instructions of the executable instructions to splice all the URBs converted from the subimages back into the image, wherein the second instructions correspond to a USB device driver;
- and
- the processor being further configured to executed third instructions of the executable instructions to obtain the image from the USB device driver, wherein the third instructions correspond to a USB application program.
