Referring to Fig. 5 A, for using the structural representation of a kind of portable terminal device under closure state of above-mentioned the application's method the 3rd embodiment, when auxilliary screen is set, can on the non-LCD display surface of main screen, have chute, on auxilliary screen slide rail is set, the cooperation by slide rail and chute can overlap or stretch out from main screen auxilliary screen with main screen in the process of sliding; Angular transducer can be arranged on any one side of two parallel opposite side of auxilliary screen and its direction of stretching out from main screen (perhaps slide rail slide chute direction).
Referring to Fig. 5 B, for using the structural representation of a kind of portable terminal device under opening of above-mentioned the application's method the 3rd embodiment, from Fig. 5 B, can see, after auxilliary screen level on the main screen is stretched out, should can also be rotated around the shaft by auxilliary screen, should also can rotate by auxilliary screen simultaneously along with the rotation of main screen, and owing to projection module can't rotate this moment, if still carry out orthogonal projection then image that projection goes out will produce distortion, therefore can calculate compensating parameter by the angle value that display control module detects according to angular transducer to image, according to this compensating parameter output image is proofreaied and correct, projected to auxilliary screen by projection module again and be the image that does not have distortion.
Above-mentioned projection module can be built in the inside (for example being placed on the position of CD-ROM drive) of notebook computer, this projection module and notebook computer are by electrically connecting, the power supply of notebook computer is given this projection module power supply, and the shows signal of the auxilliary screen of notebook computer is as the signal input of this optical projection system.Adopt the auxilliary screen of common projection screen as double-screen notebook, can reduce the cost of double-screen notebook, also alleviated the weight of double-screen notebook simultaneously, projection screen can be a front projection screen, also can be rear projection screen.Suppose definition β angle and θ angle, wherein the β angle is the angle of projection screen and notebook host face, and scope is preferably spent between 180 degree 0, and the θ angle is the angle of projection screen and lcd screen, and scope is preferably spent between 270 degree 180.
When pulling out projection screen, projection screen can change along with the change (being the change at β angle) of lcd screen position, and projection screen can be around the rotating shaft rotation (being the change at θ angle) of lcd screen simultaneously.Wherein, sensor is usually located on the projection screen, is used for surveying the change of projection screen position, promptly surveys the size at current β angle of projection screen and θ angle.Describe in detail below according to the distortion in images compensation principle, to projecting to the process that the image on the screen compensates of assisting in the embodiment of the present application:
When projection screen during perpendicular to the exiting surface of projection module, the image projection of projection module output can not produce distortion to projection screen, suppose that β angle at this moment and θ angle are remembered respectively to make β
0And θ
0When the position of projection screen changes, can distort to projection screen through the image projection of exporting after the projection module projection, the shows signal of supposing the notebook computer output image is D (x
d, y
d), D (x
d, y
d) be D through the orthoscopic image of exporting behind the projection module
p(x
p, y
p), the display image of this image on projection screen is D
s(x
s, y
s), establish H
pTransformation matrix for projection module then has
D
p＝H
p·D (1)
If projection screen is vertically over against the light-emitting window of projector, promptly when β=90 °, during θ=180 °, D then
s=D
p, the image on the screen is undistorted, this moment projection screen the position as initial position;
If the position of projection screen changes, promptly variation has taken place in β angle and θ angle, so the no longer vertical light-emitting window over against projector of projection screen, D so
s≠ D
p, the image D on the screen
sCan distort.Simultaneously, the sensor on the projection screen detects be changed to (Δ β, the Δ θ) of projection screen position, after the projection screen rotation, and projected image D
p(x
p, y
p) be D through the display image on screen behind the spatial alternation
s(x
s, y
s), make that R is the spatial alternation matrix of projected image, then have
D
s＝R·D
p＝R·H
p·D (2)
And by Δ β, Δ θ, the value of D, according to the relation of space projection, the spatial alternation matrix that can determine projected image is R, by Δ β, the value of Δ θ, according to the relation of space projection, the space that can determine projected image is changed matrix and is:
In order to make the image D on the projection screen
s(x
s, y
s) undistorted, need be to the shows signal D (x of output image
d, y
d) carry out distortion compensation in advance, make that the distortion compensation matrix is K, so the shows signal behind the distortion compensation is KD, the output image D of projection module
Pk(x

p, then have
D
pk＝H
p·(K·D) (3)

sk＝R·D
pk＝R·H
p·(K·D)＝D
p (4)
According to formula (1) and (2), can get again,
K＝H
p -1·R
-1·H
p (5)
Hence one can see that, when the projection screen position changes, can detect its variable quantity (Δ β, Δ θ) by sensor, obtains the spatial alternation matrix R of projected image, simultaneously the transformation matrix H of laser projection
pThe build-in attribute that belongs to projection module.So when the position of projection screen changes, can obtain corresponding distortion compensation matrix K according to above-mentioned formula (5), thus realize to fault image from normal moveout correction.
In the foregoing description, show the angle theta angle of projection screen and lcd screen, and the image compensation process of the angle β angle of projection screen and notebook host face when all changing, i.e. Δ β among the spatial alternation matrix R of projected image, the image compensation process that Δ θ is all non-vanishing.It is to be noted, as Δ β, there is a value non-vanishing among the Δ θ, and another value is when being zero, then be equivalent to projection screen and only on a dimension, variation taken place, therefore above-mentioned two angle values are brought among the spatial variations matrix R of projected image, promptly one of them angle value is zero bringing among the spatial variations matrix R, still can calculate the distortion compensation matrix K corresponding to the one-dimensional space in the manner described above.
Referring to Fig. 6 A, be the inner synoptic diagram that shows control structure of a kind of portable terminal device of using above-mentioned the embodiment of the present application, wherein auxilliary screen is in user mode: main frame provides power supply signal by built-in power to projection module and display control module, to guarantee the operate as normal of these two modules.Wherein, main frame is input to display control module with the display image signals of video card output, the rotation angle value that is installed in the auxilliary screen that the angular transducer on the auxilliary screen will detect simultaneously is transferred to display control module, display control module is according to the record in the foregoing description, according to the distortion compensation parameter that calculates image is adjusted, and adjusted image is transferred to projection module, the projection module projected image is gone up for the user to auxilliary screen and is watched.
In addition, if auxilliary screen then still can utilize projection module to carry out orthogonal projection under unused state in the foregoing description.Referring to Fig. 6 B, be the inner synoptic diagram that shows control structure of auxilliary screen portable terminal device under unused state: at this moment, auxilliary screen does not stretch out from main screen, main frame provides power supply signal by built-in power to projection module, and to guarantee the operate as normal of this module, main frame is directly inputted to projection module with the display image signals of video card output simultaneously, projection module carries out orthogonal projection with the display image that receives, promptly at the meeting occasion, can directly display image be projected on the wall, watch jointly for the participant.
