Abstract

The invention discloses a device and a method imparting a keyboard function to camera equipment. The device comprises an additional device, the camera equipment and a processing module which are sequentially connected. The additional device comprises a box and a panel. The box is internally provided with the camera equipment and provided with one side which is opened and which serves as an image collecting window of the camera equipment. The panel allows light to transmit and provides a keyboard key map. The panel is formed by adding a lighting key plate and a multi-hole panel. The processing module comprises a key scanning unit, an anti-shaking delay unit and a key processing unit. The device and method has the advantages that the conventional camera function of the camera equipment is maintained, and the keyboard function is imparted simultaneously.

Description

Technical field [0001] The invention relates to a device and method for realizing keyboard functions based on imaging equipment, and belongs to the technical field of computer input equipment. Background technique [0002] At present, known computer keyboards have two kinds of hard keyboards and soft keyboards. A hard keyboard refers to a physical keyboard, which is composed of a circuit board, a casing, etc.; a soft keyboard refers to an application program that uses software simulation to realize keyboard functions. The hard keyboard takes up a lot of space, and it is inconvenient to place it at will, such as being used in the hand; the soft keyboard is operated with a mouse, which is not very convenient. Contents of the invention [0003] The present invention aims to realize a device and method for realizing the keyboard function by using the camera equipment. This invention not only retains the original camera function of the camera equipment, but also can be used as...
