Embodiment
Please refer to Fig. 1 and Fig. 2.Fig. 1 is the functional-block diagram of image scrolling system 10 of the present invention, and Fig. 2 is the synoptic diagram of the display 14 of image scrolling system 10.The present invention is a kind of image scrolling system 10 that is used for the image frame 11 in scrolling one form 12, image frame 11 is the part of a file, its position that corresponds to this document can be with a coordinate (x, y) represent that wherein x and y are respectively image frame 11 in transverse axis of this document and the position on the Z-axis.
Image scrolling system 10 includes a storer 16, be used for stored routine and data, one processor 18, be used for carrying out the program that is stored in the storer 16, one Genius mouse 20 is electrically connected on processor 18 as input media, and an operating system 26 (for example Microsoft's Window 98), be stored in the operating system memory block in the storer 16, be used for the operation of control system 10.Operating system 26 includes a display control program 28, is used for controlling the demonstration of form 12.Image scrolling system 10 includes an application program 30 (for example Netscape browser) in addition, be stored in the application storage district in the storer 16 and be executed in operating system 26 times, it can utilize display control program 28 to come image frame in the scrolling form 12, and an input media control program 32, be stored in the input media control program memory block in the storer 16 and be executed in operating system 26 times.
Genius mouse 20 includes a scrolling signal generator 34 and is used for producing the scrolling of scrolling signal with the image frame in the control form 12.The scrolling signal can be an one-dimensional signal or a 2D signal.When this scrolling signal is one-dimensional signal, can be used to control image frame 11 scrolling along level or vertical direction in form 12, and when this scrolling signal is 2D signal, then can be used for controlling image frame 11 scrolling along level and vertical direction in form 12 simultaneously.Input media control program 32 is the control program of Genius mouse 20 just, be to be used for receiving and handle the scrolling signal that Genius mouse 20 transmits, and the scrolling signal after will handling reaches application program 30, with the image frame in the scrolling form 12.
Please refer to Fig. 3, Fig. 3 is the synoptic diagram of Genius mouse 20.Genius mouse 20 includes a housing 22, and the bottom of housing 22 is provided with an opening 24.Scrolling signal generator 34 includes a pressure transducer (sensor) 36, be installed on the top of housing 22, and corresponding two-dimentional scrolling signal be pressed and be produced to pressure transducer 36 can towards different directions by a finger, with the two-dimentional scrolling of the image frame 11 in the control form 12.
Please refer to Fig. 4, Fig. 4 is the synoptic diagram of a pressure conversion table 52 of being scheduled to.Each dimension scrolling signal all has a pressure conversion table 52 corresponding with it in the two dimension scrolling signal, pressure conversion table 52 is used for the pressure that pressure transducer 36 is born is converted to scrolling signal corresponding with it, wherein the horizontal shafting of pressure conversion table 52 is that pressure transducer 36 is pressed the order code that the back produces, and Z-axis is the scrolling signal that corresponds to each order code.Each two-dimentional scrolling signal that input media control program 32 can will receive converts a corresponding two-dimensional quantitative to according to the corresponding pressure conversion table 52 of each dimension scrolling signal, and foundation one predetermined formula is converted to motion vector (Δ x, Δ y) with this bivector.And input media control program 32 can be with this motion vector (Δ x, Δ y) with form 12 in the coordinate (x of image frame 11, y) produced a new coordinate (x+ Δ x mutually, y+ Δ y), then should new coordinate (x+ Δ x, y+ Δ y) imports application program 30 into so that image frame 11 is able to be scrolled to the indicated position of this new coordinate (x+ Δ x, y+ Δ y).
Please refer to Fig. 5, Fig. 5 is the synoptic diagram of image frame 11 in the form 12.Image frame 11 includes a main viewfinder 44 and a vertically scrolling 46, and vertically scrolling 46 is provided with a scroll box that can move in the vertical direction 48, and the scrolling of image frame 11 is carried out by following instruction: 1.GetWindowRect
The width (W) of the main viewfinder 44 of reading images picture 11 and height (H) data; 2.GetScrollInfo
Read on the altitude information (nPage), scroll box 48 of scroll box 48 edge (nMin) and lower edge (nMax) position on edge position (nPos) and the vertically scrolling 46; 3. the * K+ Δ d of Δ P '=(F*nPage/H)
F is the measured pressure of pressure transducer 36;
NPage/H is scroll box 48 and vertically scrolling 46 ratio highly, and it is equal to the height (H) of main viewfinder 44 and the ratio of file total length;
K is a constant;
Δ is the residual surplus step that does not reach the integer step number of previous step motion vector (Δ P);
Calculate Δ P ' and can get next step motion vector of image frame 11,4.nPos '=nPos+ Δ P '
NPos is the position of image frame 11 in former coordinate time scroll box 48 upper limbs 50;
The position of nPos ' scroll box 48 upper limbs 50 that are image frame 11 to the new coordinate; (5.if nPos '＜0) nPos '=0;
if(nPos′＞(nMax-nPage))nPos′＝nMax-nPage
The boundary condition (boundary condition) of scroll box 48 has been defined in this instruction; 6.SendMessage (hWnd, WH_VSCROLL,
MAKELONG(SB.THUMBTRACK，nPos′)，NULL)
Wherein the MAKELONG instruction directly defines the position of edge 50 on the scroll box 48, so image frame 11 can move by very smooth-going floor-covering roll; 7.SetScrollPos (hWnd, SB_VERT, nPos ', FALSE)
This instruction can be upgraded the position of scroll box 48 upper limbs 50.
Since the scrolling signal be converted into earlier motion vector again with form 12 in the coordinate of image frame produced new coordinate mutually, and make image frame be scrolled to the indicated position of new coordinate, therefore image scrolling system 10 can point (pixel (pixel)) be a unit, very smooth-goingly the image frame in the scrolling form.When the user needs the scrolling image frame, as long as press pressure transducer 36 on the Genius mouse 20 towards the direction of needs with a finger, image frame just can be by smooth-going ground scrolling, so the user do not have the bad impression that picture is beated, and the user does not need to be dependent on scroll bar yet and carries out scrolling.
Genius mouse 20 includes the bottom that an index signal generator 38 is installed on Genius mouse 20 housings 22 in addition, is used for detecting the displacement of housing 22 and produces corresponding two dimensional pointer signal.Index signal generator 38 includes a spin 40, be installed on opening 24 inboards in rotatable mode, and two optical encoder 42 be installed in the housing 22, be used for doing mutually in order to detect the displacement of spin 40 along two vertical direction with spin 40, and produce corresponding two dimensional pointer signal, be shown in the displacement of a vernier of display 14 with control.And the demonstration of the vernier of display 14 is controlled by display control program 28.After input media control program 32 is received the index signal that Genius mouse 20 transmits, input media control program 32 can handle these index signals and will handle after index signal reach the displacement of display control program 28 with the vernier of controlling display 14.
Compared to known technology, image scrolling system 10 of the present invention utilizes scrolling signal generator 34 scrolling that the scrolling signal carries out image frame that produces of Genius mouse 20.The scrolling signal can be converted into corresponding bivector, is converted to motion vector again, and the coordinate of the image frame in motion vector and the form 12 is produced a new coordinate mutually then, and image frame is then scrolled to the indicated position of this new coordinate.Because image scrolling system 10 of the present invention is modes with coordinate, promptly is to be that unit comes the image frame in the scrolling form with the point, therefore scrolling image frame very smooth-goingly, the user does not have the bad impression that picture is beated.
