Writing pencil of the present utility model, built-in acceleration sensor and picture processing chip in writing pencil, acceleration transducer induction obtains the written handwriting data of writing pencil when writing, then by picture processing chip, written handwriting data are processed, the character that user uses writing pencil to write can be identified, realize, by paper document electronization, being conducive to the long-term preservation of written contents, and being convenient to follow-up inquiry; Not need written contents, by the intelligent terminals such as artificial mode input computer, to greatly reduce typing workload.

Accompanying drawing explanation

Fig. 1 is the schematic flow sheet of the utility model writing pencil first embodiment;

Fig. 2 is the schematic flow sheet of the utility model writing pencil second embodiment.

The realization of the utility model object, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.

Embodiment

Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

The utility model provides a kind of writing pencil, with reference to Fig. 1, in one embodiment, this writing pencil comprises acceleration transducer 10 and picture processing chip 20, wherein: acceleration information when acceleration transducer 10 is for responding to the motion of described writing pencil on three direction of principal axis, sends to picture processing chip 20 by described acceleration information; Picture processing chip 20 is for obtaining character corresponding to described acceleration information according to acceleration information identification.

Wherein, acceleration transducer 10 is preferably three-axis gyroscope.

Writing pencil is when writing, acceleration transducer 10 can sense its acceleration on three direction of principal axis, by the accekeration on three direction of principal axis, the movement locus obtaining the nib of writing pencil when writing can be analyzed, record the movement locus of this nib, then the movement locus of this nib is sent to picture processing chip 20.

In the present embodiment, picture processing chip 20 can be existing picture processing chip, such as, can be DSP process chip etc.Picture processing chip 20 can utilize the movement locus of existing image processing means to nib to process, such as, binary conversion treatment is carried out to written handwriting data, obtain the binary image only having black and white two kinds of gray scales, then binary image is carried out discretize, the digital feature information of each character in matrix data is obtained after extracting sliding-model control, in this way, after the digital feature information getting the character that user writes, can identify digital feature information, more adequately obtain the character that user writes.

In the present embodiment, the character identified can be Chinese character or other character, as English character or French character etc.

The present embodiment can be applied in a lot of scene based on the recognition methods of the character of writing pencil:

1, reporter's field notes press spokesman answers emphasis, writing pencil is used to carry out record by the present embodiment in writing process, the content recorded can convert electronic document in time, below electronic document is slightly made an amendment and just can send out news release, ensure the real-time of news, do not need to carry out typing according to document;

2, student uses writing pencil to take notes on classroom, by notes synchronized upload in the terminals such as mobile phone, it can be facilitated to check notes at any time, do not need to carry special notebook, and have obvious advantage in notes inquiry and arrangement;

3, staff uses writing pencil to do meeting summary, meeting summary can synchronized upload to computer, save staff in the operation manually carrying out after the meeting arranging;

Use writing pencil to take travel notes when 4, going out, can the trouble of carrying the relatively large electronic equipments such as computer be removed from, and the miniaturized electronics input efficiencies such as carrying mobile phone are lower.
