Problems solved by technology
However, the disadvantage of using a unified interface driver is that the UVC protocol standard only defines the basic functions of some cameras, and for the current camera function requirements on the market, using the unified driver that comes with the operating system cannot achieve video special effects , face tracking, background transformation, photo frame and other popular camera special effects functions
This increases the complexity of use to a certain extent. For some people who are not familiar with computers, it brings great inconvenience in use. For many people who like simplicity and convenience, it is also a factor that affects product satisfaction. shortcoming

The invention discloses a device driven by a USB video class (UVC) application automatic replacing system. Parts of contents in the current control set item in a registration table system path, which are recorded by a uniform UVC driver are modified according to stored equipment information by reading and storing the information of an equipment manufacturer name, an equipment model, and the like from a configuration file of the system, whether drive program information supplied by a manufacturer occurs currently is judged in a system service item, and a new subitem is established and a key value is modified respectively under different conditions so as to finally replace the uniform UVC driver of an operation system by a manufacture driver. The device driven by a UVC application automatic replacing system greatly simplifies the operation of the drive installation of a UVC camera and leads some users with unskillful computer operation to be capable of easily installing the drive and accordingly using the special function and other unique operations which are respectively supplied by products of all manufacturers.
Description
technical field [0001] The present invention relates to the application of USB Video Class (abbreviated as UVC), in particular to an installation device for UVC device drivers. Background technique [0002] USB Video Class is a standard protocol for a device class defined by the USB organization. Under the Windows XP SP2 operating system, Microsoft has defined four types of USB devices that do not need to install additional drivers. The specific classifications include: 1. USB Video Class (USB Video Class), referred to as UVC, mainly refers to camera products; 2. USB Audio Class (USB Audio Class), referred to as UAC, mainly refers to the USB sound card; 3. USB Human Interface Device (USB Human Interface Device), mainly refers to devices such as mouse and keyboard with USB interface; 4. Storage device class (USB Mass Storage Device), mainly refers to the USB flash drive. At present, these four kinds of USB devices can realize driverless in the Windows operating system. The ...
