Background technology
The spy opens the 2002-7027 communique and has disclosed according to the moving of the housing of the portable device able that constitutes portable terminal device or portable phone etc., the technology of the image that shows in display part of rolling.For example, if the user of hand-held this device moves this device to right, then image rolls to right too.The unit that moves as the sensing housing has adopted angular-rate sensor.For example, detect the value as the angular-rate sensor benchmark, the variation from reference value is exported as electric signal, the result makes picture rolling according to output.
Yet, the angular-rate sensor that in this instrument, uses, its reference value changes because of environment temperature, just causes temperature drift.Temperature drift is exported as low frequency, and the rolling of image is had harmful effect.For example, though user's mobile device not, can be created in also that image that display part shows rolls without authorization or picture to a class misoperation that allows the different direction of the direction of its rolling roll with the user.
The Electronic apparatus, signal compensation apparatus and the method for compensating signal that provide the temperature drift that can prevent owing to angular-rate sensor to cause misoperation are provided in view of this class situation.
Summary of the invention
In order to address the above problem, the feature of the Electronic apparatus of emphasis of the present invention is to possess: the angular-rate sensor of exporting 1st signal corresponding with sense of rotation angular velocity; Store the unit of data of the 2nd signal of the original output of described angular-rate sensor of stationary state in advance; Be used to detect the unit of stationary state; When detecting described stationary state, extract the unit of the difference of described the 1st signal and described the 2nd signal out; According to the described differential signal that is drawn out of, the unit that described the 1st signal is compensated; According to the described signal that is compensated, the display part that picture roll is shown.
The action of human arm is a fulcrum with ancon or shoulder.The action that the user allows housing move aloft is similar to the sphere action.As long as for the speed that detects this arm action detects along the arm translational speed of sphere is angular velocity.
The relation of acceleration and speed is generally represented with following formula.
Acceleration

The detection action of angular-rate sensor of the present invention is that the action that the display part limit is moved device is being seen with eyes in the user limit, is long wavelength's low frequency.Therefore, the action that device is moved will influence each other with above-mentioned low frequency based on temperature drift.
According to the present invention, the value of temperature drift is extracted in the output of the angular-rate sensor in the time of can remaining static by comparison means out, and based on this value, output that can the offset angle speed pickup.
In the present invention, be stored in the output of the angular-rate sensor of the device that a certain temperature remains static in advance.Then, detection is such as the output of the angular-rate sensor of the device that remains static in another temperature.The poor of the reference value that changed because of temperature drift extracted in more detected output and the output of angular-rate sensor of storage in advance out.The output of angular-rate sensor had overlapped based on the output of moving with based on the output of temperature drift when device was moved.The difference of the reference value of being extracted out is equivalent to the output based on temperature drift.Therefore, remove the poor of the reference value of being extracted out by the output of angular-rate sensor when device is moved, just can only obtain based on mobile output.The angular velocity of supposing this drift part is Δ ω k, and amended rolling amount becomes formula 3.

(angular-rate sensor and acceleration transducer)
Next according to Fig. 3 A to Fig. 6, angular-rate sensor and the acceleration transducer that is arranged on display device 1 described.
Fig. 3 A and Fig. 3 B are the content of expression about angular-rate sensor.Fig. 4 A and Fig. 4 B are the result curve of expression from angular-rate sensor output.Fig. 5 is the content of expression about acceleration transducer.Fig. 6 is the installation site of expression angular-rate sensor and acceleration transducer.
Angular-rate sensor 12 is that the angular velocity of display device 1 sense of rotation is surveyed, and the element of exporting as voltage, for example be, with mobile detection side be the rectangular shape that the length of 1cm, vertical direction is respectively 0.5cm and 0.3cm to the length of parallel direction.
It is action on the sphere at center that the action of human arm can be similar to ancon or shoulder.As shown in Figure 3A, when the user moves this display device 1, for example can become along being the action of α direction of the sphere of fulcrum with ancon 28.And in order to detect the responsiveness of this arm, can detect along the arm translational speed of sphere is that angular velocity gets final product.Generally represent with the length velocity relation of acceleration with following formula.
Acceleration
, speed
(acceleration) ... formula 1
Can know from formula 1, if having sense acceleration such as acceleration transducer described later, just can obtain speed by on certain hour width t, resulting data being carried out integration.And if obtained the translational speed of the display device 1 of certain certain hour, then can further obtain displacement by this velocity amplitude being carried out integration, can determine the rolling amount of picture.
Yet, obtain the displacement of display device 1 from acceleration, must carry out time-based 2 repeated integrals, therefore respond slow or easily produce cumulative errors.And as mentioned above, in order to detect the action of arm, as long as detect angular velocity.So the present invention has adopted angular-rate sensor 12 as the means that detect amount of movement.
If ask the rolling amount of picture according to angular velocity, formula 2 then arranged.
Rolling amount
(angular velocity) ... formula 2
Angular-rate sensor 12 mainly is to be used for the vibrations that the touch because of hand of detected electrons instrument etc. causes.The vibrations that cause because of the touch of hand are high frequencies of short wavelength.When the vibrations that the touch that detects because of hand causes, for example filter low frequency and only export high frequency with Hi-pass filter etc.Based on the output of temperature drift because be low frequency and being filtered.Therefore, when the vibrations that the touch that detects because of hand causes, can not produce the problem that occurs misoperation because of temperature drift.
The detection action of angular-rate sensor 12 is that the action that display part 6 limits are moved display device 1 is being seen with eyes in the user limit, is long wavelength's low frequency.The action that display device 1 is moved will influence each other with the low frequency based on temperature drift.
Be stored in the output of the angular-rate sensor 12 of the display device 1 that a certain temperature remains static in advance.Then, detection is such as the output of the angular-rate sensor 12 of the display device 1 that remains static in another temperature.The poor of the reference value that changed because of temperature drift extracted in more detected output and the output of angular-rate sensor 12 of storage in advance out.The output of angular-rate sensor 12 had overlapped based on the output of moving with based on the output of temperature drift when device was moved.The difference of the reference value of being extracted out is equivalent to the output based on temperature drift.Therefore, remove the poor of the reference value of being extracted out by the output of angular-rate sensor 12 when display device 1 is moved, just can only obtain based on mobile output.The angular velocity of supposing this drift part is Δ ω k, and amended rolling amount then is a formula 3.
Rolling amount after the compensation
Formula 3
The angular velocity of 12 pairs of α direction rotations of angular-rate sensor is surveyed, and exports as voltage.Output is represented with the variation that starts from reference voltage.For example, arm length be the user of 45cm when 0.2 second chien shih display device, 1 rotation, 5 degree rotation angle, the displacement voltage of angular-rate sensor 12 is about 10mV.And the reference voltage of angular-rate sensor 12 is about 1.5V.The value of the angular velocity of output is removed high fdrequency component by not shown such as low-pass filter.Removed the output of high fdrequency component, carried out time integral with numerical integrating, calculated the displacement component of display device 1 by CPU15.
And, angular-rate sensor 12 is owing to be the angular velocity of only surveying a sense of rotation, so shown in Fig. 3 B, stride under the situation of two above sense of rotation such as α direction and the action of β direction 2 directions, be necessary that corresponding turning axle separately is provided with angular-rate sensor 12 in detection.In this case, angular-rate sensor 12 outputs are applied to the angular velocity α durection component and the β durection component of display device 1.The output result carries out time integral by CPU15 with numerical integrating by low-pass filter 29, calculates each displacement component of display device 1.
Testing result such as Fig. 4 A based on angular-rate sensor 12.The longitudinal axis of curve shown in Fig. 4 A is the output voltage (V) of angular-rate sensor 12, and transverse axis is time (second).Include component that moving of the display device that detects because of angular-rate sensor 12 produced in this output result's the waveform, because of the component that vibrations produced of the touch of hand etc., because of the component that temperature drift produced of angular-rate sensor 12.Fig. 4 B represents that this result has been removed the situation of the high frequency of hand touch component by low-pass filter 29.Comprise component that moving of the display device that detects because of angular-rate sensor 12 produced in this waveform and because of the component that temperature drift produced of angular-rate sensor 12.At this moment display device 1 is corresponding with the output voltage values of angular-rate sensor 12, makes picture roll.Because output voltage is a low frequency,, its detection promptly reaches high frequency so there is no need the variation of the trickle voltage of hand touch of Fig. 4 A etc.If handle this trickle variation in the same old way, trickle vibrations also can take place and become to be very difficult to watch in the demonstration of image when then rolling.Therefore, remove useless high frequency with low-pass filter 29.
Fig. 5 represents for example the situation of acceleration transducer as the sensor use that detects 3 direction of principal axis acceleration.Longitudinal direction component, transverse direction component and fore-and-aft direction component that detection is applied to the acceleration of display device 1 carry out the time integral computing by each component, calculate speed component, displacement component.
And display device 1 is if stationary state, and then to display device 1 no acceleration effect, the output voltage of acceleration transducer 13 becomes the voltage when not applying acceleration.The displacement of the unit interval output voltage of acceleration transducer 13 just is 0.Thus, become the voltage (displacement of unit interval output voltage is 0) when not applying acceleration, also can survey the stationary state of display device 1 by confirming output from acceleration transducer 13.Thus, do not need the sensor that detects stationary state is set in addition, can avoid the complicated of disposal system and the processing of realization high-level efficiency.
The result of calculation of angular-rate sensor 12 and acceleration transducer 13 is used to the compensation of temperature drift described later and the rolling of image.
As shown in Figure 6, display part 6 is covered 6c, liquid-crystal apparatus 6d, angular-rate sensor 12 and acceleration transducer 13 and is constituted by lining lid 6a, frame 6b, table.Angular-rate sensor 12 is provided with 3, is respectively to survey angular-rate sensor 12a, the angular-rate sensor 12b that detection Y direction moves, the angular-rate sensor 12c that detection Z direction moves that directions X moves.Angular-rate sensor 12a and 12b paste the inboard of paying at lining lid 6a.Angular-rate sensor 12c pastes the outside of paying at frame 6b.Angular-rate sensor 12 is rectangular parallelepipeds, the long 1cm of length direction.Because the length direction of angular-rate sensor 12c is parallel with the thickness direction of display part 6, so if be arranged on the inboard of display part 6 then obstruction can become the slimming of display part 6 own the time.Therefore, angular-rate sensor 12c is set at the outside of frame 6b.
An acceleration transducer 13 is set.One is enough detected moving of X-direction, Y direction, Z-direction.Acceleration transducer 13 it is desirable to and angular-rate sensor 12a and the approaching setting of angular-rate sensor 12b, is separated with distance certainly and is provided with also passable.Angular-rate sensor 12 is connected with CPU15 through low-pass filter 29, A/D converter 27 with acceleration transducer 13.
(treatment process)
Below, according to Fig. 7 and Fig. 8, the processing of picture rolling is described.
Fig. 7 represents to move to from display device 1 treatment process of the CPU15 of picture rolling.Fig. 8 represent the longitudinal axis be voltage (V), transverse axis be temperature (℃) time the temperature drift of angular-rate sensor 12.
As shown in Figure 7, CPU15 confirms at first whether the user supresses reset button 10 (step 701).If reset button 10 is pressed, then saves the operation of step 702 and step 703 and enter the operation of step 704.If reset button 10 is not pressed, then read the output voltage (step 702) of acceleration transducer 13.Then, in order to differentiate whether display device 1 is stationary state, by acceleration transducer 13 sense acceleration.If the output of acceleration transducer 13 is 0 then enters next step, if output is not 0 then the processing (step 703) of repeating step 701 and step 702.
When the displacement of supressing the output voltage of reset button or acceleration transducer 13 as the user was 0, CPU15 read the output voltage (step 704) of angular-rate sensor 12.Then, read out in the flash memory 17 output voltage (step 705) of angular-rate sensor 12 storage, that under certain temperature, remain static, the value from the output voltage of the angular-rate sensor 12 that reads in step 704 is subtracted value after the value of the output voltage that is taken at the angular-rate sensor 12 that step 705 reads as side-play amount extraction (step 706) based on temperature drift.
The value of exporting from angular-rate sensor 12 when next, reading (step 707) such as user's mobile display device 1.Deduct the side-play amount of extracting out from this output valve, then removed based on the change in voltage of temperature drift and calculate based on the displacement (step 708) of moving in step 706.Provide the indication (step 709) of rolling image according to this value.
Handle the action problem of having eliminated based on temperature drift like this.
About above-mentioned treatment process, be that example is carried out schematic illustration with moving of a direction.
Angular-rate sensor 12 is when the stationary state temperature variation, and output is as the curve β of Fig. 8.Curve α represents that angular-rate sensor 12 moves the output valve when a certain amount of.Be to make curve β carry out parallel moving in the voltage axis positive dirction.Output valve wherein such as 20 ℃ the time is made as θ and stores flash memory 17 etc. into.
Be example such as with 40 ℃ the time.In the time of 40 ℃, the output of the angular-rate sensor 12 of stationary state is β 1.In this calculating of carrying out step 706, read out in the value θ of storage in the flash memory 17, get the poor of β 1 and θ, extract the side-play amount that causes because of the said temperature drift out.If side-play amount at this moment is a Δ, following formula is arranged then.
Δ＝θ-β1
Further in the time of 40 ℃, the user is the output valve that display device 1 moves when a certain amount of α 1.Carry out the calculating of step 707 at this, α 1 adds that Δ calculates compensation output.If compensation at this moment is output as ω, following formula is then arranged,
ω＝α1+Δ
＝α1+(θ-β1)
＝α1-β1+θ
Compensation output ω is temperature independent and be certain.If the θ value from ω deducts storage flash memory 17 then obtains (α 1-β 1).This is to move the displacement that produces because of reality.Therefore, get final product based on the value of (the α 1-β 1) image that rolls.
In a word, in fact as long as the curve β 1 of storage display device 1 stationary state, in that the user is actual when utilizing this display device 1, by getting the poor of the output voltage (output voltage of curve α 1 certain temperature) that makes display device 1 move certain temperature when a certain amount of and the output voltage of curve β 1 under its temperature, only just can detect the mobile displacement that causes because of display device 1.Therefore, store curve α 1 as default value in the time of can dispatching from the factory at the finished product of display device 1.
(making use-case)
Next, the action when using this display device 1 to buy content describes.
Fig. 9 is the process flow diagram of its action of expression.
In a single day display device 1 drops into power supply, then shows initial picture (step 901) at display part 6.Figure 10 is the figure of this initial picture one example of expression.In the picture of display part shown in Figure 10 6, " menu ", " restaurant ", " shop ", " cinema ", " eating house ", " map ", " picture ", " character input " etc. are for example arranged, on this picture, do not show but also have other project in its lower section, by display device 1 is moved down, can and see following project picture rolling downwards.And, selectable project highlighted (symbol 37 among Figure 10) on present picture, press OK button 7a after, 37 of highlighted projects are selected.This highlighting such as being fixed on the picture as mentioned above by making picture rolling come mobile project, can select to want the project 37 that highlights.
At this, if display device 1 is moved up and down (step 1102), then this display device 1 and this mobile corresponding picture of display part 6 that makes are such as scroll-up/down (step 1103).Highlight desirable project such as " picture " by the user, press (step 904) behind the OK button 7a, then show the selection picture (step 905) of " picture " at display part 6.
Here too, if display device 1 by move up and down (step 906), then this display device 1 and this mobile corresponding picture that makes display part 6 are such as roll up and down (step 907).Select (step 908) behind 1 image by the user from each available content images A1, A2 of being divided into 4 images, B1, B2, as shown in figure 11, display device 1 shows amount of money hint images 38 (steps 909) at display part 6.On this picture 38, such as the amount of money display part 39 that the displaying contents amount of money is arranged, buy ACK button 40, a plurality of content is bought button 41.After pressing a plurality of contents and buying button 41, return initial picture once more and can append the content of buying again.
In addition,, in 4 image A 1, A2, B1, B2, make earlier that the image of maximum area highlights in display frame, select suitable outstanding picture by rolling, get final product with OK button 7a chosen content about above-mentioned selection.
The prompting of the corresponding content amount of money, behind user in selecting content, then selecteed content is such as being provided to display device 1 (step 910) through the Internet from server.
The user is by making display device 1 suitably mobile, can roll the image of seeing in display part 6 content displayed 44 45.
When Figure 13 represents to have selected " map " the project from initial picture shown in Figure 10, image one example that shows at display part 6.If from this state mobile display device 1 (step 906), with picture such as roll up and down (step 907), select on the map decide image (step 908), then can be shown to display part 6 to more detailed map as selected content, and store storage medium 8 into such as its zone.
In above action, although can not cause display device 1 is remained static, but still occur the problem of the misoperation of rolling because of the temperature drift image of angular-rate sensor 12.
And the user also can press the temperature drift that reset button 10 is come offset angle speed pickup 12.Thus, misoperation will be prevented from.
And, by amount of movement, can not be subjected to the influence of acceleration of gravity to come the amount of movement of pick-up unit with the angular-rate sensor pick-up unit.
The present invention is not limited to above embodiment.
