In the present embodiment, pilferage is inferred in variation with the state that is provided with that installs (here for posture is set), just think to exist and just carry out user's authentication (for example judging) when changing with the input password, miscellaneous operation (formality) of the authentication check that always exists in the simple prior art, reduce the frequency that the authentication check chance takes place, reduce miscellaneous degree of operation.
Fig. 1 is the block diagram of the projection type video display device of expression first embodiment.In Fig. 1, the 101st, projection type video display device, the 111st, the input terminal of received image signal (not drawing among the figure), the 110th, the input signal of the signal processing stipulated from the picture signal of input terminal 111 input is handled I/F, the 104th, to the picture signal of handling I/F110 output from input signal decode, the image processing of conversion etc. and the graphics processing unit that screen shows, the 112nd, amplify and be incident upon the projection optics unit of treated image in the graphics processing unit 104, the 113rd, the screen of projection image projected.The 105th, constitute action button by a plurality of buttons on the basket that sets the device that do not draw in the drawings, the 106th, usefulness infrared ray (Infrared) remote signal (below, simple be " IR remote signal ") to projection type video display device carry out remote control remote controller (below, simply be " remote controller "), the 107th, accept IR photo detector from the IR remote signal of remote controller 106, the 108th, as the angle that is provided with of checkout gear and gravity formation, angular transducer from the parts that posture change is set of the variation reading device of this detected value, the 109th, control is from the I/O controller of the input of IR photo detector 107 and angular transducer 108, the 102nd, carry out the Central Processing Unit (following simple for " CPU ") (central processing unit) of the calculation control of projection type video display device integral body, the 103rd, the various memory of data of the program of storage Controlled CPU 102 and the user mode of device and password etc., handle I/F110 from the picture signal (not drawing the figure) of input terminal 111 inputs at input signal, carry out predetermined process in the graphics processing unit 104, will for example project on the screen 113 with the corresponding optical image of picture signal (image) by projection optics unit 112.The operation of the on/off of device and the function that has of device, setting etc. is undertaken by action button 105 or remote controller 106, and CPU102 correspondingly carries out corresponding processing respectively with through the IR remote signal of the button of being operated (not drawing among the figure) in the action button 105 or IR photo detector 107,109 receptions of I/O controller.
For example, by in advance to the operation of action button 5, setting prevents in the situation of starting (startup) of the anti-locking system of improper use of improper use of projection type video display device, when starting (startup) when making the device energized, CPU102 obtains the angle that is provided with by angular transducer 108 detected projection type video display devices by I/O controller 109.Contrast obtains is provided with angle and is registered in the angle that is provided with in the memory 103 by proper user in advance, calculates the variable quantity that posture is set.CPU102 has or not pilferage according to this variable quantity judgement, judges whether to carry out user's authentication.CPU102, later operation is not carried out in permission when judgement authenticates, and when not being such, carries out user's authentication, if the input of the operation by for example action button 105 is registered in password in the memory 103 by proper user in advance, then the operation of device is carried out in permission.We will at length state the processing of above-described CPU102 in the back with flow diagram.
In angular transducer, exist have one, two, three angle detects axle, but also can be with wherein any one as angular transducer 108.As the detected memory 103 that angle-data is set of storage, for example can enumerate EEPROM and FLASHROM etc. again.In addition, when the equal function of built-in and I/O controller in CPU102 109, also can be with each device that is connected with the I/O controller direct and CPU couple together.
Below, we illustrate the work of treatment of the CPU102 relevant with the anti-locking system of improper use with the flow diagram of Fig. 2, Fig. 4.Fig. 2 is that the flow diagram of handling is set in the starting (startup) of the anti-locking system of the improper use of expression.After energized, when the action button 105 by Fig. 1 or remote controller 106 send the indication that starts the anti-locking system of improper use, CPU102 begins the startup of the anti-locking system of improper use and sets processing in step (following simply is " S ") 201, through I/O controller 109, detect the angle [alpha] that is provided with that posture is set shown in Figure 3 in the device user mode, present embodiment in this moment of expression by angular transducer 108, be registered in (S202) in the memory 103.Then, as shown in Figure 3,, urge the user to authenticate the password registration of usefulness with graphics processing unit 104 display requirements registration password picture.And when finishing the password registration by the user by action button 105 or remote controller 106, CPU102 is registered in (S203) in the memory 103 with password.Here, password refers to the special pattern of the arrangement of the arrangement of designation number sequentially and literal or demonstration or presses the sequence numbering of specific button/remote control keys etc.Below, projection type video display device is in anti-locking system this situation in startup of improper use is registered in (S204) in the memory 103, finish improper use and prevent system start-up setting processing (S205), after, begin common operate as normal.
Fig. 4 is that the flow diagram of the work disposal of locking system is prevented in the improper use of carrying out work after the expression energized immediately.In Fig. 4, when connecting the power supply of projection type video display device 101, CPU102 begins the work (S401) of the anti-locking system of improper use, and the improper use of confirm at first whether the startup of the anti-locking system of improper use is set (connection), confirming to be stored in the memory 103 prevents the state (S402) that system start-up is set.If do not set the startup that locking system is prevented in improper use at S402, then advance to S410, intactly make the device operate as normal.If set the startup of the anti-locking system of improper use at S402, then angle [alpha] (S403) is set by what angular transducer 108 detected that the expression user modes promptly are provided with posture, contrast this detected angle (below, be called " detecting angle ") is set and is registered in the memory 103 angle [alpha] (S404) is set.At this moment, consider the precision of angular transducer 108, also can in the contrast that angle is set that detects angle and registration, allow to exist the detection error of angular transducer, the gap (enough and to spare) about for example about ± 2 degree.And, detect the angle that is provided with of angle and registration when contrast, judge consistent or in error range the time, think and in user mode (here for posture is set), do not change, do not steal, advance to S410, intactly begin operate as normal, finish the work disposal (S411) of the anti-locking system of improper use.Angle is set not simultaneously when what detect angle and registration at S404, pilferage has taken place because infer, so normal running beyond S405 forbids the power supply opening operation, with graphics processing unit 104 demonstrations requirement input password picture 501 as shown in Figure 5, urge input password (S406), judge at S407 whether the password of input is consistent with the password of registration.In addition, forbid the normal running in addition of power supply opening operation, till the password by action button 105 or remote controller 106 input registrations, this is self-evident.When the password of judging input at S407 is consistent with the password of registration, cancellation requires input password picture 501 (S408), releasing is to forbid (S409) of normal running, and beginning operate as normal (S410) finishes the work disposal (S411) that locking system is prevented in improper use.At this moment, when the password of continuous stipulated number (for example 5 times) input error, both can only forbid inputing password, also can not use fully.
As mentioned above, if according to present embodiment, then by detecting the variation (variation of posture is set in the present embodiment) of user mode, the improper use that supposition is caused by pilferage, carry out authentication check,, then judge the improper use that does not cause by pilferage if do not detect variation, because can omit the formality of authentication check, so the miscellaneous authentication check can eliminate common use the time.That is, miscellaneous operation of authentication check is simplified, suppress operability and reduce, one side realizes the anti-locking system of the improper use of projection type video display device.
Again, in projection type video display device, in order to proofread and correct by porjection type picture distortion (so-called trapezoidal distortion) that angle causes etc. is set, originally just carrying the angle transducer, at this moment also it is also used as the user mode detector, do not need to append new angular transducer, thereby can not cause cost to rise.
In addition, in the situation that has detection axle as angular transducer 108 with two or three, by with the plane parallel that constitutes by two planes that constitute detecting quadrature in the axle with by gravity direction and projecting direction install, not only can detect angle is set, and can differentiate setting (basal plane is placed and is provided with) and the aerial suspension setting (the aerial suspension is provided with) that is placed on the floor, can further limit posture is set.For example in the situation of the angular transducer 108 that has the biparous angle detection of tool shown in Figure 6 axle, by according to by detecting axle 601 and detecting axle 602 planes that constitute and install with the parallel plane mode that projecting direction 604 by gravity direction 603 and projection type video display device constitutes, can angle be set with detecting axle 601 detections, differentiate setting and the aerial suspension setting that is placed on the floor with detecting axle 602.Here the so-called above-mentioned setting that is placed on the floor is the top state that up is provided with that makes device.So-called again aerial suspension setting is the state that device reversally is provided with up and down, for example as shown in Figure 7, is to be installed in the method that is provided with that can see in situation on the ceiling 702 etc. will installing 101 with fixer (aerial suspension is provided with metalwork) 701.
Again, except the anti-locking system of the improper use described in the present embodiment, for example as shown in Figure 8, if on the part of seeing easily on the basket of projection type video display device 101, attach the forbidden logo mask 801 of warning normal running when the state that is provided with is changed wrongly, people around then can making knows that the anti-locking system of improper use starts, and can more effectively suppress to steal.
Fig. 9 is the block diagram of the projection type video display device of expression second embodiment.In first embodiment, infer pilferage with the variation that posture is set, but in a second embodiment, as shown in Figure 9, replace angular transducer 108, with geomagnetic sensor 901 detect as a form of user mode direction (please refer to table 1) is set, infer with the variation that direction is set and steal.The others of present embodiment are identical with first embodiment, omit the explanation to them here.
Below, we state the 3rd embodiment.Figure 10 is the block diagram of the projection type video display device of expression the 3rd embodiment.In first embodiment, infer pilferage with the variation that posture is set, but in the 3rd embodiment, as shown in figure 10, replace angular transducer 108, with distance measuring sensor 1001 detect projection distances or with the distance of wall, read the variation that place (please refer to table 1) is set from detected variable in distance, infer and steal as a form of user mode.The others of present embodiment are identical with first embodiment, omit the explanation to them here.
Below, we state the 4th embodiment.Figure 11 is the block diagram of the projection type video display device of expression the 4th embodiment.In first embodiment, infer pilferage with the variation that posture is set, but in the 4th embodiment, as shown in figure 11, without angular transducer 108, the CPU102 landscape of monitor camera 1101 checkout gear peripheries, read the variation that the place is set from the variation of the peripheral landscape of detected device, prediction is stolen.Example as the landscape of checkout gear periphery, for example as shown in figure 12, can enumerate in the projection lens side and have monitor camera 1101, detect and the landscape 1201 of registration projecting direction as peripheral landscape, the method for inhibiting apparatus normal running when the landscape beyond the landscape that detects registration.
In first embodiment, infer to steal from the variation that posture is set, but in the 5th embodiment with angular transducer 108, in Fig. 1 without angular transducer 108.In the present embodiment, CPU102 handles I/F110 with input signal and detects from the signal of input terminal 111 inputs and change, and changes the variation of the input state that reads input terminal from detected signal, infers and steals.As the example that the signal that detects input changes, for example can enumerate registration the signal of XDA, 85Hz is input to the state of rgb signal input terminal, the method for inhibiting apparatus normal running etc. when the input of the signal beyond the signal that detects registration.
Below, we state the 6th embodiment.Figure 13 is the block diagram of the projection type video display device of expression the 6th embodiment.In first embodiment, infer pilferage with the variation that posture is set, but in the 6th embodiment, as shown in figure 13, without angular transducer 108, detect the insertion of connector or plug 1301 to input terminal 111, read the variation of the input state of input terminal from the insertion that connectorless or plug 1301 are arranged, infer and steal.As detection connectorless or the plug example to the insertion of input terminal is arranged, for example can enumerate and be used in the insertion that has or not the RCA plug in the input terminal with the RCA socket detection of switch, registration has the state of insertion, when the method that detects inhibiting apparatus normal running when not inserting etc.
Below, we state the 7th embodiment.Figure 14 is the block diagram of the projection type video display device of expression the 7th embodiment.Figure 15 is the figure of the stationary state of expression projection type video display device.In addition, in Figure 14 on the key element that has with the common function of Fig. 1 additional identical label and omit explanation to them.
Present embodiment can be advantageously applied to, and as shown in Figure 7, with fixing metal instrument (aerial suspension is provided with metal tools) 701 grades projection type video display device 101 is fixed on situation on ceiling 702 grades for example.In the present embodiment, shown in Figure 14, Fig. 15, from having the no-trump device to be fixed to fixture (being ceiling here) with fixed screw 1401 and switch 1402 are detected, the variation of reading (perception) stationary state is inferred and is stolen.
In first to the 7th embodiment, with the variation of the state that is provided with in the user mode shown in the table 1 promptly (1) be provided with that posture, (2) are provided with direction, (3) are provided with place, (4) to the input state of input terminal, the variation of (5) stationary state, prediction is stolen, but use the variation of the set condition of device in the 8th embodiment, prediction is stolen.Figure 16 is the block diagram of the projection type video display device of expression the 8th embodiment.In addition, in Figure 16 on the key element that has with the common function of Fig. 1 additional identical label and omit explanation to them.
In the present embodiment, as shown in figure 16, with potentiometer 1602, detect the position of the projection lens 1601 of projection optics unit 112, read the variation that focuses on the varifocal set condition from the change in location of detected projection lens, infer by stealing and wait the improper use that causes.
Below, we state the 9th embodiment.In the present embodiment, replace using and infer by the variation of the varifocal focus settings state of the detected lens of potentiometer of the 8th embodiment and to steal, and with projects images distortion (so-called trapezoidal distortion) corrected value.Because posture being set and, in projects images, producing distortion of device to the distance of screen.In order to proofread and correct this distortion, usually the image projected data are carried out distortion correction and handle.In the present embodiment, the reference record that distortion correction is handled is in memory, the CPU102 that writes down, relatively be recorded in last projects images distortion (so-called trapezoidal distortion) corrected value of setting of device user in the memory 103 and the projects images distortion correction value of registering by proper user in advance, read the variation of projects images distortion correction value, infer by stealing and wait the improper use that causes.At this moment hardware becomes the formation of the angular transducer 108 of removing Fig. 1.But, as shown in figure 25, nonvolatile memory 103 has and storage is set by the storage area of setting the corrected value 1 that the regular user that registered in handling produces in the system start-up of Fig. 2 be stored in the constituting of storage area of the corrected value 2 that has changed in addition the common processing respectively.
In the situation of present embodiment, because will in device starts, be used to detect improper use, so perhaps allow improper use up to once through the corrected value of revising 2.For example, in the situation of the improper anti-locking system that does not have password with remove wrongly in the situation of the locking that produces by password, improper use may take place.Owing to the place is set and that the position is set is different, the situation that needs to change projects images distortion correction value is a lot of in the situation of improper use.In this case, should the change value be stored in the nonvolatile memory 103 as corrected value 2.Promptly, when existing change the requiring of corrected value, judgement is in the system start-up setting of Fig. 2 is handled or in handling usually, when setting in the processing in system start-up correction data is stored in the corrected value 1, in handling usually correction data is being stored in the corrected value 2.When started next time, relatively Cun Chu corrected value 2 and from regular user's corrected value 1 according to whether consistent, judged whether it is improper use.
In addition, also can form following structure, the comparison of corrected value when being not limited to the device energized, and is carried out in predetermined timing.Perhaps, also can form following structure: will require the shearing device power supply as opportunity, different at corrected value 1 with corrected value 2, do not input at stipulated number under the condition of regular password, after cutting off the electricity supply, forbid that next device starts.At this moment, nonvolatile memory 103 constitutes has the sign that inhibiting apparatus starts, and when dump, sets up the processing of this sign.When being in improper use and preventing in the system start-up state, when starting, device checking that inhibiting apparatus starts the startup that the laggard luggage of sign puts and handles.
In the situation of above-mentioned processing, when when the access device power supply, carrying out the system start-up of Fig. 2,, in Fig. 4, when starting, next device also necessarily requires password even if regular user sets change again.Therefore, just wish before requiring to cut off the electricity supply, to carry out immediately the system start-up of Fig. 2.Thereby, also can form when existing and cut off the electricity supply when requiring, on screen, demonstrate the formation that the ejection of proposing start-up system shows (popup menu) soon.Perhaps, also can form when change setting, require the formation of input password.
Further, in Figure 25, form respectively and will be stored in the memory 103 by first corrected value of regular user's input and second corrected value of process change when handling usually, by relatively the two detects the formation of the change of corrected value, but also can form storage area with corrected value as one, exist the sign of the meaning of change to be stored in formation in the memory 103 expression.At this moment, CPU102 by when device starts or the predetermined timing checkmark of power supply when disconnecting etc., detects and has change, the use of restraint device.Further, in first embodiment, when when the variation of the user mode of device infer to be stolen, the normal running beyond forbidding cutting off the electricity supply, but the operation that also can forbid changing the projects images corrected value in the present embodiment.
In the tenth embodiment, CPU102 relatively is recorded in the projects images counter-rotating set condition that the last projects images counter-rotating of setting of device user in the memory 103 is set (so-called mirror setting) state and registered by proper user in advance, read the variation that the projects images counter-rotating is set, infer by stealing and wait the improper use that causes.The situation of present embodiment will be registered in the different storage area of nonvolatile memory 103 with the set condition of being implemented in normal condition by regular user or irregular user 2 by the set condition 1 that regular user registers according to the processing of Fig. 2 respectively.Similarly to Example 9, perhaps allow at least 1 time improper use again.At this moment projects images counter-rotating set condition 2 and the set condition 1 relatively set, whether consistent according to setting content, detect improper use.In addition, about timing relatively, when being not limited to insert power supply similarly to Example 9.In first embodiment, when the variation of the user mode of reading device is inferred when stealing, the normal running beyond forbidding cutting off the electricity supply, but also can forbid changing the operation that the projects images counter-rotating is set in the present embodiment.
