As shown in Figures 3 and 4, Fig. 3 is the synoptic diagram of cursor control device 40 of the present invention, and Fig. 4 is the circuit block diagram of cursor control device 40.Cursor control device 40 is a Genius mouse, and it comprises that a housing 42, is located at the spin 44 of housing 42 bottom sides, two optical sensors 46, a linear image input media 48 and an image-processing circuit 54; Two optical sensors 46 are located in the housing 42, are used for sensing spin 44 and roll on two mutual vertical direction and produce a two dimensional cursor signal; Linear image input media 48 is located at the upside of housing 42, is used to import a linear image; Image-processing circuit 54 is located in the housing 42.
Image input media 48 includes first and second linear sensor 50,52, is located at abreast in the housing 42, is used for the linear image of sensing and produces corresponding linear signal of video signal respectively.Image-processing circuit 54 connects two linear sensors 50,52, is used to receive and handle linear signal of video signal that two wires sensor 50,52 imported to produce a displacement signal.
Cursor control device 40 connects a computer system 60, and computer system 60 connects a display 62.Computer system 60 includes a memory body 64, a processor 66, an input media control program 68 and a display control program 70; Memory body 64 is used for stored routine and data, processor 66 is used to carry out the program that is stored in memory body 64, input media control program 68, driver as cursor control device 40 is stored in the memory body 64, be used to receive and handle the displacement signal that image-processing circuit 54 produces, display control program 70 is stored in the memory body 64 as the application program of software WORD and so on, is used for the scrolling according to form 72 on the displacement signal control display 62.The image-processing circuit 54 of cursor control device 40 also can be located in the quick system 60 of computer, receives and handle the linear signal of video signal that two linear sensings 50,52 are imported.
Extremely shown in Figure 7 as Fig. 5, Fig. 5 is the synoptic diagram of a finger fingerprint 80, Fig. 6 is that fingerprint 80 is by image input media 48 time, first and second linear signal of video signal 84,86 that first and second linear sensor 50,52 produces respectively, Fig. 7 be in two linear signal of video signal 84,86 by linear image 88,90 that several bit values constituted.When a figure, for example when the image input media 48, first and second linear sensor 50,52 can produce several first and second linear signal of video signal 84,86 to a finger fingerprint 80 in regular turn along a predetermined direction.Because each linear signal of video signal contains a predetermined number bit (bit), the linear signal of video signal 84,86 that linear sensor 50,52 is produced can form the linear image 88,90 that is made of several bit values respectively.The linear sensor of the different piece of fingerprint by image input media 48 50,52 o'clock can form different linear images 88,90 in the linear signal of video signal that linear sensor 50,52 is produced.Image-processing circuit 54 then can write down each first and second linear signal of video signal 84,86 with and time of producing.In this embodiment, fingerprint 80 moves a unit from top to bottom, and therefore, the first linear sensor 50 can produce 0011010100 and 0101000110 signal in regular turn, and the second linear sensor 52 can produce 0101000110 and 0010111100 signal in regular turn.
When image-processing circuit 54 by first and second linear sensor 50,52 when receiving up-to-date linear signal of video signal (0101000110 and 0010111100) respectively, the linear image (10100011 and 101111) of the finger literary composition in the up-to-date linear signal of video signal can be compared with the linear image (110101 and 10100011) of the previous interior fingerprint of first and second linear signal of video signal (0011010100 and 0101000110) that writes down, because the first linear signal of video signal 0101000110 that the second linear sensor, the 52 previous second linear signal of video signal 0101000110 that produce and the first linear sensor 50 produced afterwards is identical, and the first linear sensor 50 is located at the position in the second linear sensor, 52 the place aheads, image-processing circuit 54 can learn that fingerprint 80 is towards bottom offset one unit, and can include the corresponding one dimension or the two-dimension displacement signal of speed according to the mistiming generation one between two groups of linear signal of video signal of generation.In this embodiment, image-processing circuit 54 can produce the one dimension displacement signal of the unit displacement amount that moves down, therefore, and the downward scrolling of form 72 meetings one unit on the display 62.
When the first linear sensor 50 produces 0011010100 and 0110101000 linear signal of video signal in regular turn, and the second linear sensor 52 is when producing 0101000110 and 1010001100 linear signal of video signal in regular turn, image-processing circuit 54 can be with first and second linear sensor 50, the 52 linear signal of video signal (0110101000 that produced afterwards, 1010001100) the linear image data (110101 of interior fingerprint, 10100011) with the previous linear signal of video signal that writes down (0011010100,0101000110) the linear image data (110101 of interior fingerprint, 10100011) compare, because two linear sensors 50, the linear image of fingerprint is identical in the 52 linear signal of video signal that successively produce, image-processing circuit 54 can produce an one dimension displacement signal that is moved to the left that includes speed according to producing mistiming between two groups of linear signal of video signal, therefore, the form on the display 62 72 is understood scrolling one unit distance left.
When the user will control the scrolling of the form 72 on the display 62, as long as the user utilizes its finger finger tip contact and moves through image input media 48, just form 72 can reach the scrolling effect along with direction and the speed that fingerprint 80 moves.
Compared with prior art, the present invention has following effect:
The image input media 48 of cursor control device 40 of the present utility model is to utilize two linear sensors 50,52 and fingerprint 80 to produce the displacement signal of scrolling form 72, and is easy to use, reliable.
More than narration is to utilize embodiment that architectural feature of the present invention is described, is not to be used to limit protection scope of the present invention.
