Problems solved by technology

However, when using these methods to realize character input, it is necessary to make these portable terminals additionally configure corresponding hardware, so that the cost is relatively high, and because additional equipment is required for character input, it is extremely inconvenient for users to use

Embodiment approach

[0080] In a preferred embodiment, before querying a pre-trained gesture contour model library according to the gesture contour image information of the object to obtain a matching gesture contour model, the method further includes:

[0081] (1) performing binarization processing on the collected object gesture contour image information; and / or,

[0082] (2) performing image sharpening processing on the collected object gesture contour image information; and / or,

[0083] (3) Perform image smoothing processing on the collected object gesture contour image information.

[0084] Taking the binarization processing, image sharpening processing and image smoothing processing of the collected object gesture contour image information at the same time as an example, since the grayscale image only has the brightness information of the spatial sampling points, it can be represented by a numerical value. For color images, the content is richer, but the representation is more complex. How...

Abstract

The invention discloses a character input method based on an image sensing module, a device and a terminal. The character input method comprises the following steps of: acquiring operation track information of an object fingertip by the image sensing module; and inquiring a character model library trained in advance according to the operation track information so as to convert the operation track information into corresponding characters. According to the invention, the personalized requirement of a user for the handheld terminal can be met, and simultaneously the fast and accurate input of the characters also can be realized.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a character input method, device and terminal based on an image sensing module. Background technique [0002] At present, mobile communication is developing by leaps and bounds, and thus, people have higher and higher functional requirements for human-computer interaction functions of mobile terminals (such as mobile phones). As an indispensable communication tool in people's daily life and work, mobile phones are increasingly being upgraded and developed towards intelligence and humanization, so as to continuously meet people's increasingly picky individual needs. [0003] Text editing and input technology has greatly changed people's communication methods since its birth. Through this technology, people can edit text messages, input characters, etc. At present, there are many ways of inputting characters, but in view of the various ways of inputting characters, they all...
