Embodiment

Further specify its embodiment below in conjunction with accompanying drawing.

A kind of scanning window 01 that is used for scan text, built-in scan device (camera or miniscanning equipment) 11; A kind of scan module 10 of realizing scan function comprises image sensor 12, digital zoom submodule 13; An execute key 02 is used for the gated sweep device and implements scanning; A kind of identification module 20 that is used for image transitions is become numerical information comprises row cutting submodule 21, perpendicular cuts submodule 22, normalization submodule 23, standard character library 24 and matched sub-block 25.A control module comprises temporary storage 03 and central processing unit 05, and temporary storage 03 is used to store intermediate images and numerical information; Realize the conversion and control of each functional module by central processing unit 05.Scan module 10 is connecting scanister 11, and temporary storage 03 is connecting scan module 10, and identification module 20 is connected with temporary storage 03.Central processing unit 05 is connecting each functional module, and the numerical information of the image information of scan module 10 and identification module 20 all is transferred to display 04 by central processing unit 05.

1, scanning window and execute key (referring to accompanying drawing 1)

Scanning window 01 is set up in the keyboard region upper left side, the convenient use, and its size is decided according to the scanister size, and scanister (camera or miniscanning equipment) 11 is wherein built-in.Execute key 02 is positioned at scanning window right side handled easily.

2, the scan function module is implemented (referring to accompanying drawing 4)

Scan control of the present utility model is carried out by scan module 10.

(1) with camera 11 embodiment is described earlier: to semi_word, (for example CMOS or CCD etc.) sends the frame two field picture that camera absorbed to display 04 by central processing unit 05 by image sensor 12 with camera in elder generation.The image size adopts digital zoom submodule 13 to adjust, its basic thought is by the processor in the electronic dictionary, each elemental area in the picture is increased or reduce, thereby reach the purpose of amplifying or dwindling entire image, can realize this function with the directionkeys on the electronic dictionary.If promptly the word that will look into can intactly be filmed (because the western language word is made up of many letters, so have characteristics to be: its lateral length is generally big than height dimension, therefore the word of desiring to look into to be placed the top of photographic images, with convenient identification), can press execute key 02, implement to take.The image of taking deposits temporary storage 03 in.What scan module here embodied is the function of digital camera.
