After this preferred embodiments of the present invention will be described with reference to the drawings.

Fig. 1 shows the example of the configuration of using information handling system of the present invention, and this information handling system can be applicable to the occasion of digital camera.

By means of be installed in various device (will be described in detail later) and the maintenance server 12 of the 11A of cinema in the 11N, the information handling system in the example of formation Fig. 1 by predetermined network such as interconnection such as Internet.In this case, maintenance server 12 for example refers to, by as a kind of employed equipment of provider that is installed in the various device of the 11A of cinema in the 11N of safeguarding of serving.

The 11A of cinema comprises a plurality of display position 22a to 22n, so that can show a plurality of films concurrently.In order to manage a plurality of display position 22a concentratedly, movie theatre management equipment 21 (after this being called TM equipment 21) is installed in the 11A of cinema to 22n.

Display position 22a comprises that projection management equipment 31a (after this being called SM equipment 31) is to screen 34a.

Similarly, display position 22n comprises that SM equipment 31n is to screen 34n.Except display position 22a, not shown each display position 22k (k be in the alphabet lowercase) arbitrarily, and display position 22n comprises that SM equipment 31k is to screen 34k.

By way of parenthesis, after this,, always abbreviate display position 22a as display position 22 to 22n as the display position 22a that needn't be distinguished from each other separately during to 22n.In addition, after this, when display position 22k is called display position 22 for short, also respectively SM equipment 31k is called SM equipment 31 to screen 34 to screen 34k.

SM equipment 31 is the equipment of carrying out the centralized management of display position 22.Miscellaneous equipment in the SM equipment 31 control display positions 22, that is, and material server 32, projector 33 etc.In addition, SM equipment 31 is communicated by letter with TM equipment 21, so that send and receive whereabouts when needed and from the various information of TM equipment 21.

Material server 32 provides the numerical data of the film (material) that will show for projector 33 in display position 22.

Projector 33 is at the image of screen 34 upslide shadows corresponding to the numerical data that provides from material server 32.Thereby on screen 34, run a picture.

Though not shown in this Figure, other the 11B of cinema has one or more display positions 22 similarly to 11N.Provide SM equipment 31 to screen 34 for each display position 22.

As mentioned above, the information handling system of Fig. 1 is applied to the occasion of digital camera.In the occasion of digital camera, defined a kind of standard of the DCI of being called as standard by the tissue that is called as DCI (digital camera group)." as an image parameter that relates to, the white peak value brightness of screen center is 48cd/m in this standard code ²(14ft-L) ".With 14ft-L=48cd/m ², the center of screen 34 may need the brightness of every square metre of about 48 candle lights (candle).In other words, the brightness (illumination) that projects to the image on the screen 34 may remain on constant level constantly at all.

On the other hand, according to capacity of display position 22 etc., the size of screen 34 greatly changes.

Therefore, according to the size of the screen 34 of carrying out projection thereon, may need to use can satisfy the DCI standard optimum lamp for example xenon lamp as the light source of each projector 33.

In addition, visual angle about film, there is all size, comprises for example having aspect ratio 1: 1.33 " normal size ", have aspect ratio 1: 1.66 " Vistavision size (European standard) ", have aspect ratio 1: 1.85 " Vistavision size (Unite States Standard (USS)) " and have aspect ratio 1: 2.35 " CinemaScope size (registered trademark) ".Therefore, may be at same display position 22, that is, a predetermined angle of view on identical screen 34 from various visual angles is changed into another visual angle.In this case, may need to change the convergent-divergent multiple of the camera lens of projector 33.Change according to this, may need to change the power (input watt) of lamp, so that as mentioned above the brightness (illumination) of the image on the screen 34 is remained constant level.Therefore, the gain of the light quantity of lamp may need to be stabilized in the amount of a regulation.Therefore, may need to use it can adapt to the lamp of this change, and carry out suitable setting in a side that drives lamp as the minimum watt of specified input (after this this specified input is also referred to as the lamp model) and maximum watt etc.

Light fixture has the life-span.Therefore may need correctly to manage the service time of lamp etc., so that change lamp with the suitable cycle.This is because some lamp may need annual at most approximately replacing 8 times.

In addition, lamp is inserted into predetermined lamp box (for example, the lamp box 57 of Fig. 2 in the present embodiment).Therefore, the shape of lamp self is identical or similar, so that guarantee to bring into play its function (for example, adopting the shape of Fig. 3 in the present embodiment).Yet, the lamp model is not clearly stipulated, thus the lamp of the various lamp models that distributing on the market.Especially when the 11A of cinema of Fig. 1 when 11N is dispersed in away from each other position, the lamp that uses the lamp manufacturer (manufacturing person) in each zone to make usually.In this case, more increased the possibility of the lamp of the different lamp models that on the market of different regions, distributing.Therefore, even when projector 33 on the screen of identical size the projected image of the 11A of cinema in the 11N, the lamp that also may use different lamp models is as the lamp in the projector 33 of packing into.

Therefore, about being used for the lamp of the projector in the digital camera occasion, there is situation specific to this digital camera occasion.As a result, the variety of issue that describes below has taken place in the cinema that uses existing projector.

For example, there is a kind of existing projector with power supply (after this being called the lamp power supply unit) of the lamp that can drive multiple lamp model.In this case, in the past, the workman who changes lamp is provided with the lamp power supply unit by hand according to the lamp model that will carry out the lamp of changing.Replacedly, change the be provided with lamp of selecting predetermined lamp model of the workman of lamp according to the lamp power supply unit.In this case, the workman who changes lamp can carry out wrong setting owing to operating mistake, or has selected wrong lamp.In this case, there is electric current to surpass to flow through the rated current of lamp, thus and the danger of the fault of blasting etc.In this case, the lamp of mistake refer to the lamp model not with the lamp that coupling is set of lamp power supply unit.The unmatched reason that is provided with of lamp model and lamp power supply unit may be that the selection of lamp model itself is wrong, though or the selection of lamp model itself is correct, but because the shape of lamp is identical or similar usually, and can not only determine the lamp model, prepare lamp model and the different lamp of selected lamp model mistakenly by visual inspection.When in the existing projector that the lamp of the lamp model of the cut-and-dried scope that is provided with that can not Perfect Matchings lamp power supply unit is packed into, this lamp even can not use at first glance.After this this problem is called lamp model problem.

In addition, for example,, in existing projector, also provide to be used to measure the lamp timer of service time (after this being called the lamp timer) owing to need suitably to manage service time etc. of lamp as mentioned above.Yet in the past, can wait replacement lamp timer by the operator in the display position 22 at any time.Therefore, even when finishing in the assurance time of life-span at lamp of lamp, have no idea formally to prove that the life-span of lamp has finished in the assurance time of lamp.That is, when finishing in the assurance time of life-span at lamp of lamp,, may provide free new lamp according to for the free specific protocol that lamp concludes etc. of changing.Yet, this agreement of having no idea to determine whether to carry out.In addition, the projector of the lamp of the multiple lamp model of can packing into comprises such part, and the replacing time in its cycle is according to light quantity (lamp model) and difference.When the replacing of determining this part during the time, part replacing personnel (server) have no idea to check that indication used the historical information of which lamp.After this, this problem is called lamp use historical problem.

In addition, for example, as mentioned above, can wait the existing lamp timer of resetting by the operator in the display position 22 at any time.Therefore, existence can not the strict control lamp possibility of service time.In addition, as mentioned above, even can easily in projector, use the lamp that did not prove at existing projector.With regard to applicability (for example, cooling, drive current, mechanical dimension etc.), this lamp is not suitable for this projector usually.As a result, for example exist projector to break down or the danger of lamp blast etc.After this this problem is called fluorescent tube reason problem.

In addition, in the occasion of digital camera, each 11A of cinema wishes from a plurality of lamp manufacturer's purchase lamps so that reduce maintenance cost to 11N.Therefore, as mentioned above, mixing the lamp of various lamp models on the market.On the other hand, when carrying out conversion between for example " CinemaScope size " and " Vistavision size ", as mentioned above, the brightness (illumination) that projects to the image on the screen 34 may remain on constant level constantly at all.In this case, in order to guarantee constant brightness, the light quantity gain of lamp may need to remain 1.6.Yet, in the past, can not make regulation to the scope that is provided with of cut-and-dried lamp power supply unit in some cases.After this this problem is called the lamp gain problem.

In addition, for example, past, the lamp of the projector of the lamp power supply unit that replacing time of suggestion has the lamp that can drive multiple lamp model according to packing into and different.Therefore, the operator in the display position 22 manages lamp independently and changes constantly when the recommended replacement time of lamp and lamp timer are compared.As a result, management is complicated, and exists owing to mismanagement, the danger of generation projection problem etc.After this this problem is called lamp and changes matter of time.

In the information handling system of the Fig. 1 that uses embodiments of the invention, the projector 33 that can solve above-mentioned variety of issue is installed in each display position 22.That is, projector 33 is embodiment that use projector of the present invention.Fig. 2 shows the example of the configuration of projector 33.

In the projector 33 as the example of Fig. 2, CPU (CPU (central processing unit)) 51 carries out various processing according to being stored in program in the storer 52 etc.Storer 52 is also stored CPU51 and is carried out the required data of various processing etc.

CPU51 also is connected with input-output unit 53, I/O unit 54 and input-output interface 55.

Input-output unit 53 for example is made of touch pad etc.Input-output unit 53 comprises and is used for allowing user (operator of the display position 22 in Fig. 1 etc.) to carry out the input block 71 of various operations, and the display unit 72 that is made of the display that is used for display operation description etc. etc.

I/O unit 54 is delivered in CPU51 and 56 various information that send and receive of lamp supply voltage.The object lesson of the various information of transmitting is described in the description of the step S10 of Fig. 5 by way of parenthesis, after a while.

Lamp power supply unit 56 is the power supplys that can drive the lamp 58 of multiple lamp model.That is, lamp power supply unit 56 provides suitable driving power for the lamp 58 of the lamp box 57 of packing into by I/O unit 54 under the control of CPU51.

Lamp 58 has shape shown in Figure 3 in the present embodiment.That is, in the present embodiment, each has and is used as pack into the light fixture of ability (replacing ability) of projector 33 of lamp 58 shape identical with the shape of Fig. 3 arranged.Yet these lamps can have various lamp models.Therefore, operator waits that only be difficult to determine by the shape (shape of Fig. 3) of visual inspection lamp will be as the lamp model of the lamp of lamp 58 replacements.As a result, exist to take place such as the variety of issue of above-mentioned lamp model problem etc. may.Therefore, for fear of the generation of these problems, projector 33 is carried out the lamp replacing time of the Fig. 5 that describes after a while and is handled.

Yet the shape of lamp 58 is not limited to the example of Fig. 3, and it is just enough to have this shape of the lamp box 57 of can packing into for lamp 58.In other words, the shape of lamp 58 depends on the structure of lamp box 57.That is, the lamp box in the present embodiment 57 has the structure of the lamp 58 of shape that can load map 3 just.

Therefore, projector 33 has the possibility of the lamp of the various lamp models of packing into as lamp 58.Therefore lamp power supply unit 56 is configured to be provided with a plurality of patterns (after this being called the lamp pattern) as specified output such as maximum output watt, minimum output watt and maximum current in lamp power supply unit 56.Particularly, in the present embodiment, for example, 4 lamp Mode As each in the D as shown in Figure 4 can be set in lamp power supply unit 56.As being used for being provided with one the switch of lamp Mode A, for example, in the present embodiment, the switch 73 that is provided with shown in Figure 2 is provided for lamp power supply unit 56 to D.Particularly, for example, when when switch 73 being set the lamp Mode A is set, according to Fig. 4, lamp power supply unit 56 is carried out in the scope with a maximum output watt 4.6kW, minimum output watt 2.0kW and maximum current 167A definition and is driven.

By way of parenthesis, after this will be by the specified output area of the such definition of lamp pattern, that is, maximum output watt is called model domain to the scope of minimum output watt.In other words, model domain can be described as with as MIN minimum output watt restriction output, and with the scope as the maximum output watt restriction output of maximum,, is used to limit the scope of the driving of lamp power supply unit 56 that is.Particularly, for example, the model domain of lamp Mode A refers to the scope (see Fig. 9 of after a while describing) of 2.0kW to 4.6kW.

Input-output interface 55 among Fig. 2 is connected with driver 60 with communication unit 59.Communication unit 59 controls and the communication process that comprises the miscellaneous equipment of outside SM equipment 31 and material server 32 (see figure 1)s.The communication form under this situation of specific limited not, and communication can be wire communication or radio communication.In addition, can pass through directly to connect executive communication, or by comprising the network executive communication of Internet.

In addition, communication unit 59 can obtain program from the outside by this Control on Communication, and with procedure stores in storer 52.

In the time will packing driver 60 into such as the removable medium 74 of disk, CD, magneto-optic disk, semiconductor memory etc., driver 60 drives removable mediums 74 so that obtain to be recorded in program on the removable medium 74, data etc.Where necessary program or the data transmission that obtains arrived storer 52, so that be stored in the storer 52.

Below with reference to the process flow diagram of Fig. 5, the example (after this be called and handle when the projector lamp is changed) of the performed processing when replacing predetermined lamp as lamp 58 in the processing of being carried out by the projector 33 with this configuration is described.

By way of parenthesis, will be described with reference to the object lesson of figure 6 to 9.

At step S1, CPU51 determines whether to supress lamp timer replacement button.

Till pressing lamp timer replacement button, repeat in the processing of step S1, to obtain definite result not, and the processing of the processing of execution in step S1 once more.

The example of lamp timer replacement button is described below with reference to Fig. 6.

Fig. 6 shows the example of GUI (graphical user interface) image of the setting that is used to carry out projector 33, management etc.In the present embodiment, for example, on display unit 72, show this GUI image.In the present embodiment, for example, give the function of the software push buttons 101 distribution lamp timer replacement buttons that in this GUI image, are described to " replacement ".

Therefore, after the workman who changes lamp has replaced predetermined lamp as lamp 58, for example, the workman who changes lamp is by operation input block 71, or when constituting input-output unit 53 by touch pad, execution will be changed the operation that the workman's of lamp finger etc. contacts with touch pad, press software push buttons 101.In this case, the result who determines in Fig. 5 in the processing of step S1 is for being, and therefore processing enters step S2.

At step S2, CPU51 shows in the ejection of display unit 72 enterprising portable lighter sequence code entr screens.Then, at step S3, CPU51 determines whether to have imported the lamp sequence code.

Below with reference to Fig. 7 and Fig. 8 lamp sequence code and lamp sequence code entr screen are described.

The lamp sequence code refers to when lamp fabricator (manufacturing person) makes the predetermined lamp can be used as lamp 58, by the information of arranging that with predefined procedure one or more snippets lamp information about predetermined lamp or the like forms.Comprise in " lamp information or the like " " or the like ", this is because as described later, the information except lamp information such as verification and (" verification and "/" verification and ") etc. can be included in the lamp sequence code.Specifically do not limit lamp information itself, as long as lamp information is the information about predetermined lamp.For example, can adopt the information (ID etc.) that is used for the predetermined lamp of unique identification, about the management information of predetermined lamp etc. as lamp information.

By way of parenthesis, after this lamp as the object that will be given the lamp sequence code is called as the object lamp.

For example, the lamp sequence code is provided at the object lamp.Particularly, in the present embodiment, for example, the lamp sequence code is printed on the paper medium, and this paper medium is packed and is sold with the object lamp.

Fig. 7 shows the example of structure of lamp sequence code.As shown in Figure 7, by arranging text message fragment " verification and/manufacturer code/maximum watt/minimum watt/life-span hour/lamp sequence/verification with " formation lamp sequence code.

" verification and "/" verification and " is to be used for after the lamp 58 that the object lamp is replaced with in the projector 33, whether determine in the processing of the step S3 of the Fig. 5 that describes after a while, be effective information by the workman who changes lamp as the pre-determined text information of lamp sequence code input.

Therefore, as mentioned above, when fabricator (manufacturing person) the manufacturing object lamp of lamp, must additionally create the lamp sequence code.When creating the lamp sequence code, calculate " verification and "/" verification and ".By way of parenthesis, will method that create the lamp sequence code be described with reference to Figure 12 after a while.

" manufacturer code " is one section lamp information, and is the code that is used for the lamp fabricator (manufacturing person) of identifying object lamp, or so-called maker code.

" maximum watt " is one section lamp information, and is maximum watt information of the lamp model (specified input) of indication object lamp.

" minimum watt " is one section lamp information, and is minimum watt information of the lamp model (specified input) of indication object lamp.

" life-span hour " is one section lamp information, and is the information of the demarcation life time of indication object lamp.

" lamp sequence " is one section lamp information, and be make can unique identifying object lamp information, or so-called sequence number.The GUI image that is used for lamp sequence code input projector 33 is a lamp sequence code entr screen.As shown in Figure 8, the ejection of for example carrying out image 102 as shown in Figure 8 on display unit 72 shows.

Therefore, as the workman who changes lamp when the mounting object lamp is as lamp 58 in lamp box 57, promptly, when the workman who changes lamp changes lamp 58 with the object lamp, the workman who changes lamp can be at the frame 111 of lamp sequence code entr screen 102, that is the lamp sequence code that, shows the frame 111 interior input object lamps on " sequence code " the right.In order to carry out this input, for example, use input block 71 in the present embodiment.

Simultaneously, in when the projector lamp of Fig. 5 is changed, handling, repeat in the processing of step S3, to obtain to determine the result not, and the processing of the processing of execution in step S3 once more.

In frame 111, imported the lamp sequence code candidate of object lamp at Fig. 8, and supress frame 111 right sides be described to the software push buttons 112 of " inspection " time, confirm input, and with the context notification CPU51 of input frame 111.Then, in handling when the projector lamp of Fig. 5 is changed, the definite result in the processing of step S3 becomes and is, and handles and enter step S4.

At step S4, CPU51 carries out verification and confirms and handles.

In the superincumbent expression, will be expressed as lamp sequence code candidate rather than directly be expressed as the lamp sequence code at the text message of the moment input frame 111 of the processing of step S3.Make this expression and be because in moment of the processing of step S3, may be difficult to still determine whether the text message of input frame 111 is the effective lamp sequence codes that are used as the object lamp of lamp 58 replacements, that is,, in the input operation that the workman who changes lamp carries out, comprise mistake in the moment of input.

Therefore, CPU51 may need to use the part of " verification and " corresponding to the text message in the input frame 111 as mentioned above/" verification and ", carries out and checks whether text information is the processing of effective lamp sequence code.This processing is " verification and affirmation are handled " among the step S4.

At step S5, CPU51 determines whether the result of " verification and affirmation are handled " indicates effective code.

Text message in input frame 111 (lamp sequence code candidate) is when being invalid code, and whether the definite result among the step S5, and processing enters step S6.At step S6, CPU51 carries out mistake and shows on display unit 72.Wrong in this case the demonstration refers to, for example, point out the text messages (lamp sequence code candidate) in the input frame 111 thus be the demonstration of the notice re-entered of the notice prompting of invalid code etc.For example, can realize this wrong the demonstration by showing in the zone in Fig. 8 114.Thereby finish to handle when the projector lamp is changed.

On the other hand, the text message in input frame 111 (lamp sequence code candidate) is when being valid code, and the result who determines among the step S5 is for being, and processing enters step S7.

That is, at this moment, determine that the text messages (lamp sequence code candidate) in the input frame 111 are valid codes, and therefore in below the processing text messages in the input frame 111 are considered as the lamp sequence code.

At step S7, CPU51 compares to the maximum scope (that is model domain) of exporting watt to the scope (after this being called code range) of maximum watt (max watt) and the minimum output watt that is arranged in the lamp pattern the minimum watt (min watt) that is included in the lamp sequence code.

At step S8, CPU51 determines based on the comparative result of step S7 whether code range and model domain exist the scope that overlaps each other.

When scope that nonexistent code scope and model domain overlap each other, the definite result among the step S8 is not for, and handles and enter step S9.At step S9, CPU51 carries out mistake and shows on display unit 72.Wrong in this case the demonstration refers to, for example, indication is because under the present situation, can not be used as the object lamp that lamp 58 is replaced with 56 controls of lamp power supply unit, must replace another suitable lamp again as lamp 58, or when using the object lamp, thereby the necessary notice that changes the setting of the lamp pattern in the lamp power supply unit 56 is pointed out the notice of replacement or change etc. like this.For example, also can realize this wrong the demonstration by showing in the zone in Fig. 8 114.Thereby finish to handle when the projector lamp is changed.

On the other hand, when the scope that exists code range and model domain to overlap each other, the result who determines among the step S8 is for being, and processing enters step S10.

At step S10, CPU51 is defined as lamp drive controlling scope with the scope that code range and model domain overlap each other.

Particularly, for example, when the lamp pattern that is provided with when this moment was the lamp Mode A of Fig. 4, model domain was the scope of 2.0kW to 4.2kW.In addition, for example, the minimum watt (min watt) in being included in the lamp sequence code is 1.8kW, and is included in the interior maximum watt (max watt) of lamp sequence code when being 3.6kW, and code range is the scope of 1.8kW to 3.6kW.In this case, as shown in Figure 9, with the scope that code range and model domain overlap each other, that is, 2.0kW is defined as lamp drive controlling scope to the scope of 3.6kW.

In this case, lamp drive controlling scope refers to be used as the scope that is outputed to the output power that the instruction in the order of lamp power supply unit 56 provides by the CPU51 among Fig. 2 by I/O unit 54.That is, lamp power supply unit 56 is carried out and is driven, so that provide by the output power from the instruction appointment of CPU51 for lamp 58.Therefore, by as the order of sending from CPU51, at the predetermined electric power in the instruction designated lamps drive controlling scope (in the example of Fig. 9, arriving 3.6kW) of output power for 2.0kW.As a result, lamp power supply unit 56 is carried out in lamp drive controlling scope (arriving 3.6kW for 2.0kW in the example at Fig. 9) and is driven.Thereby provide proper range interior power for lamp 58 (corresponding to the object lamp of this lamp sequence code).

After in the processing of the step S10 of Fig. 5, having determined lamp drive controlling scope like this, handle entering step S11.

At step S11, the CPU51 lamp timer T (T=0) that automatically resets.The lamp timer T that automatically resets in this case referred in the moment of the processing of step S11, carried out processing based on the decision of CPU51 oneself, and did not rely on the external command from input block 71 grades.Following " automatically " has identical connotation basically.

Then, at step S12, CPU51 carries out daily record setting (records of demarcation life time T (life-span) etc.), and beginning lamp timer management is handled.

Thereby finish to handle when the projector lamp is changed.

Carry out description (records of demarcation life time T (life-span) etc.) below to the daily record setting.

Daily record is provided with the content that is included in the lamp sequence code of importing in the processing of step S3 in the log history information that finger is used as the object lamp that lamp 58 replaces at this moment, and log history information is stored in the storer 52.Particularly, with " manufacturer code ", " maximum watt ", " minimum watt ", " life-span hour " and the content of " lamp sequence " be included in the log history information.By way of parenthesis, after this life-span hour " " content be called and demarcate life time T (life-span).

Because log history information is stored in the storer 52 like this, CPU51 can read log history information from storer 52 when needed, show log historical information on display unit 72, and log history information is offered miscellaneous equipment by communication unit 59, for example, not only comprise SM equipment 31, also comprise TM equipment 21 and maintenance server 12 among Fig. 1.

By way of parenthesis, in the present embodiment, for example, can be in zone 113 grades of the lamp sequence code entr screen 102 of above-mentioned Fig. 8 the show log historical information.

Restriction specifically is not included in the information in the log history information, as long as the information that is included in the log history information is about the information of this moment as the object lamp of lamp 58 replacements.In the present embodiment, for example, the measured value that adopts lamp timer T is as the out of Memory of lamp service time of denoted object lamp.

The processing of sequentially upgrading the measured value of lamp timer T is " processing of lamp timer management " among the step S12 of Fig. 5.Below with reference to Figure 10 the example that the lamp timer management is handled is described.

At step S31, CPU51 has determined whether to provide the instruction of end process.

Though definite processing of conditioning step S31 itself is not specifically supposed in the present embodiment, for example, when the processing of the step S11 of execution graph 5, that is, when automatic replacement lamp timer T, provide the instruction of end process.

That is, in the present embodiment, when automatic replacement lamp timer T, determined to provide the instruction of end process, and finished to handle at the lamp timer management of the lamp 58 before changing at step S31.Then, the step S12 of execution graph 5, thus restart to handle at the lamp timer management of the lamp 58 after changing.

Therefore, in the present embodiment, remove non-automatic replacement lamp timer T, the result who determines of step S31 is not, and processing enters step S32.

At step S32, CPU51 determines whether to have turned on lamp 58.

When not turning on the light 58 the time, the result who determines of step S32 is not for, and handles and return step S31, so that repeat the processing down from step S31.That is,, and close in the time period of lamp 58 circular treatment of repeating step S31 and S32 at the lamp timer T that do not reset automatically.Therefore in this time period, lamp timer T continues to keep currency.

After this, when turning on the light 58 the time, the result who determines of step S32 is for being, and processing enters step S33.In step S33, CPU51 determines whether to have closed lamp 58.

When continuing to turn on the light 58 the time, the result who determines of step S33 is not for, and handles and enter step S34.

At step S34, CPU51 increases lamp timer T (T=T+1).

At this moment, in the present embodiment, for example, rewrite the measured value of the lamp timer T in the log history information that is stored in the storer 52.Thereby manage the service time accurately of the current object lamp that uses as lamp 58.

At step S35, CPU51 determines that whether the measured value of lamp timer T is less than demarcating life time T (life-span) (T＜T (life-span)).

When the measured value of lamp timer T less than demarcating life time T when (life-span), the result who determines among the step S35 is for being, and processing is returned step S33 so that repeat the processing down from step S33.

That is, when lamp 58 is opened, demarcate life time T (life-span) unless lamp timer T reaches, repeating step S33 is to the circular treatment of S35, and is each circular treatment, with the measured value increase by 1 of lamp timer T.

After this when closing lamp 58, the result who determines among the next procedure S33 is for being, and processing returns step S31, so that repeat the processing down from step S31.

That is, till lamp 58 is opened next time, or till automatic replacement lamp timer T, the circular treatment of repeating step S31 and S32.Therefore in this time period, lamp timer T continues to keep currency.

When lamp 58 is opened, lamp timer T reaches and demarcates life time T when (life-span), and at repeating step S33 during to the circular treatment of S35, the result who determines of step S35 is not for, and processing enters step S36.

At step S36, CPU51 display lamp on display unit 72 is changed warning.Lamp changes that warning refers to point out owing to reached the service time of object lamp and demarcate life time (or as described later, will reach very soon the service time of object lamp and demarcate life time), changes the message of the current object lamp that uses as lamp 58 etc. with another lamp.

Therefore, the form that provides this message specifically is not limited to image and shows, and can be other appearance form arbitrarily, such as voice output etc.That is, restriction does not specifically provide the form of this message, as long as this form allows to provide the message that the lamp replacing time has been arrived in indication to the workman (operator etc.) who changes lamp.

In the example of Figure 10, when lamp timer T has reached demarcation life time T when (life-span), display lamp is changed warning.Yet, the time of demonstration (providing) lamp replacing warning is not necessarily limited to lamp timer T and reaches the demarcation moment of life time T when (life-span), and can adopt the time arbitrarily by deviser etc., as long as time is based on the moment (for example, demarcating life time T (life-span) certain time before) of demarcating life time T (life-span) arbitrarily for this.That is, only by determining whether lamp timer T has reached the time of being adopted, CPU51 can identical mode carry out above-mentioned lamp timer management processing in the processing of step S35.

By way of parenthesis, after the processing of step S36, handle and also return step S33, so that repeat processing down from step S33.

Handle when as mentioned above, the projector lamp that projector 33 can execution graph 5 is changed and the lamp timer management processing of Figure 10.Therefore projector 33 can solve above-mentioned variety of issue.Below this point will be described more specifically.

As mentioned above, by at the step S7 of projector 33 side execution graphs 5 to S10, automatically determine the lamp drive controlling scope that is fit to, the result suitably drives and is used as the object lamp that lamp 58 is replaced.Therefore, even when replacing as lamp 58, also can use the object lamp safely with the object lamp of the cut-and-dried scope that is provided with (model domain in the present embodiment) Perfect Matchings that can not be provided with lamp power supply unit 56.This is because be set to lamp drive controlling scope by the code range of the lamp sequence code appointment that invests this object lamp and the scope that model domain overlaps each other.In addition, in the present embodiment, in the processing of step S4, carrying out verification and confirming processing, and confirming then after the validity, determining lamp drive controlling scope, thereby can avoid because lamp blast that operator's input error causes or the danger of losing efficacy.

By way of parenthesis, be used for determining that the method for lamp drive controlling scope is not limited to above-mentioned example., notice guarantees when safe that to be defined as the method for lamp drive controlling scope just enough with being no more than the scope that is included in the maximum watt (max watt) in the lamp sequence code when only being placed on.Consider each main points, such as solving the lamp gain problem described after a while etc., wish to adopt the example of said method, that is, the scope that model domain and code range are overlapped each other is defined as lamp drive controlling method of determining range.

In addition, as mentioned above, projector 33 can be in the processing of the step S11 of Fig. 5 replacement lamp timer T automatically, in the processing of step S12, carry out the daily record setting then, and beginning lamp timer management is handled (see figure 10).Thereby, the log history information of the object lamp of replacement this moment of storage correctly, and correctly upgrade lamp service time (lamp timer T).This log history information can be shown in due course, and the outside can be outputed to.In addition, when pressing lamp timer replacement button in the processing of step S1, lamp timer T does not at once reset.Only by the verification among the step S4 and confirm to handle confirmed validity after, automatic replacement lamp timer T in the processing of step institute 11.Thereby even when finishing in the assurance time at this lamp in lamp life-span of object lamp, the lamp life-span that this daily record historical data can be used as formal object of proof lamp is ending method in the assurance time of this lamp.That is, this daily record historical data can be used as and be used for one of object of proof lamp defective material.In addition, log history information can be used as and be used for determining that its cycle changes time according to light quantity (lamp model) and the material of the replacing time of that different a part of lamps.That is, can solve lamp and use historical problem.

Though as mentioned above, foregoing description is repetition, and when pressing lamp timer replacement button in the processing at the step S1 of Fig. 5, lamp timer T does not at once reset.Only show in the clear and definite ejection of in the processing of step S2, having carried out lamp sequence code entr screen, and effective lamp sequence code is imported after this lamp sequence code entr screen then, promptly, only by the verification of step S4 with after confirming to handle efficiency confirmed property, replacement lamp timer T automatically in the processing of step S11.Therefore, can expect correct management to lamp timer T.When not being used as the object lamp of lamp 58 replacements,, the lamp sequence code should not invested the object lamp for administrative reason at projector 33 proofs.Therefore, do not import correct lamp sequence code, thereby the result that verification among the step S4 and affirmation are handled indicates invalid code, the result who determines in the processing of step S5 is not, and carries out the mistake demonstration in the processing of step S6.Thereby can avoid owing to the danger of using the object lamp of proof not to cause as lamp 58, that is, projector 33 lost efficacy, the danger of lamp 58 blasts etc.Therefore, can solve fluorescent tube reason problem.

In addition, as clearly visible from the step S7 of above-mentioned Fig. 5 to the processing of S10, the model domain that will be provided with on projector 33 sides in advance is not intactly as lamp drive controlling scope, but also consider the code range definite according to the lamp sequence code that provides from the outside, correctly determine lamp drive controlling scope.That is, in the time will designing lamp 58, can not reckon with, when packing projector 33 into from one of object lamp of the various lamp models of a plurality of lamp manufacturers (lamp fabricator), based on the lamp sequence code that invests the object lamp from outside input code scope.Therefore, can easily optimize lamp drive controlling scope.As a result, can guarantee the maximum lamp gain safely.That is, can solve the lamp gain problem.

The demarcation life time of lamp changes according to lamp manufacturer (lamp fabricator) and lamp model (specified input), even and identical lamp also can be improved aspect the life-span.In this case, in the present embodiment, as mentioned above, the demarcation life time that is used as the object lamp that lamp 58 replaces was included in the lamp sequence code as " life-span hour ", and will " life-span hour " as in the lamp timer management of above-mentioned Figure 10 is handled with lamp timer T demarcation life time T (life-span) relatively.Then, demarcate life time T when (life-span) when lamp timer T reaches, display lamp is changed warning in the processing of the step S36 of Figure 10.Even this means when in the object lamp that will have various demarcation life times any one replaces with lamp 58, can provide automatically corresponding to the lamp of the demarcation life time of object lamp and change warning, that is, can solve lamp and change alert matter of time.

In addition, the measured value of sequential update lamp timer T in the lamp timer management of Figure 10 is handled, and will demarcate in the storer 52 that life time T (life-span) is stored in Fig. 2, read as the part of the log history information of the object lamp that is used as lamp 58 so that can be at any time.Therefore, as shown in figure 11, for example, can be easily in the service time (measured value of lamp timer T) and the ratio of demarcating life time T (life-span) that show on display unit 72 grades under the present situation.It should be noted that, in this case, displaying ratio (%) rather than regular time (hour etc.), even thereby will have in the object lamp of various demarcation life times any one and replace with lamp 58 time, also this ratio can be on display unit 72 grades, shown, and the display format of Figure 11 need not be changed.

In addition, as clearly visible from the configuration of Fig. 1, projector 33 can be directly or brief introduction be connected to external unit, and by directly or indirectly communicating by letter with external unit, to send and receive various information from external unit.

Therefore, for input information, needn't use the input block 71 of the projector 33 of Fig. 2, and can use the input function of external unit, for example, the input function of SM equipment 31, this not shown personal computer etc.Similarly,, the display unit 72 of the projector 33 of Fig. 2 needn't be used, and various function such as Presentation Function, the sound output functions etc. of presenting of external unit can be used for presentation information.Particularly, for example, can use the Presentation Function of SM equipment 31 or this not shown personal computer etc.

Thereby for example, the workman of replacing lamp etc. can use SM equipment 31 or this not shown personal computer to import the lamp sequence code of the object lamp of replacing as lamp 58, and presents the various information based on the log history information of this object lamp.

In addition, not only can easily the log history information as the object lamp of being scheduled to the lamp 58 in the projector 33 be transferred to SM equipment 31 and TM equipment 21, but also can be transferred to maintenance server 12.Therefore, can be unit with display position 22, be unit or be unit that with cinema 11 the concentrated area management is used as the log history information of each object lamp of each lamp 58 in a plurality of projectors 33 with the maintenance service of a plurality of cinemas 11.

Use lamp sequence code in the above-mentioned example with the state that is printed on label or paper medium.Yet the lamp sequence code is not limited to above-mentioned example especially, and can produce the effect that is equal to or is better than above-mentioned example by using other medium such as bar code, IC (integrated circuit) chip etc.Because compare with label or paper medium, bar code, IC chip etc. can be applicable to more various purpose usually, so can produce the effect that is equal to or is better than above-mentioned example, thereby application such as the bar code of lamp sequence code, IC chip are caused various uses probably, and in this case, can expect to be better than the effect of above-mentioned example.

By, for example, the lamp sequence code that the equipment (not shown) that makes lamp manufacturer (manufacturing person) use is carried out Figure 12 produces processing, can easily create the lamp sequence code with so various potential.

Figure 12 indication lamp sequence code produces the example of handling.

At step S51, this equipment receives the lamp information by inputs such as lamp manufacturers (manufacturing person).

In this case, lamp information refers to be included in the information except " verification and "/" verification and " in the information in the lamp sequence code.When employing had the lamp sequence code of structure of above-mentioned Fig. 7, for example listed in the frame as the step S51 of Figure 12, lamp information referred to " manufacturer code ", " maximum watt ", " minimum watt ", " life-span hour " and " lamp sequence ".Needn't be with identical method, or needn't import each section lamp information in this example in the identical moment.In addition, do not limit the order of input especially.

Under any circumstance, when having imported all lamp information, handle and enter step S52 from step S51.

At step S52, this equipment rearranges lamp information.This rearranges the structure that meets the lamp sequence code.Therefore, when employing has the lamp sequence code of structure of above-mentioned Fig. 7, rearrange lamp information with " manufacturer code ", " maximum watt ", " minimum watt ", " life-span hour " and the order of " lamp sequence ".

At step S53, the verification of the lamp information that this calculation of equipments rearranges like this and.That is, calculate " verification and "/" verification and ".

At step S54, this equipment produces the lamp sequence code.That is, by the verification of will in the processing of step S53, calculate with add on the lamp information that in the processing of step S52, rearranges, produce the lamp sequence code.For example, when employing has the lamp sequence code of structure of Fig. 7, produce by arranging that information that text message fragment " verification and/manufacturer code/maximum watt/minimum watt/life-span hour/lamp sequence/verification with " forms is as the lamp sequence code.

Not only can use hardware, but also can carry out above-mentioned processing sequence with software.When carrying out this processing sequence with software, the program that will constitute this software from program recorded medium is installed on the computing machine that is combined in specialized hardware, for example, be combined in the computing machine that comprises CPU51 in the projector 33 of above-mentioned Fig. 2, maybe can be by various programs are installed thereon, carry out the computing machine of various functions, for example, general purpose personal computer.

As shown in Figure 2, for example, by removable medium 74 as package media, or by the storer 52 of interim or permanent storage program, the storage of unshowned hard disk formation will be installed on computers among Fig. 2, and be set to the program recorded medium of the program of the state that can be carried out by computing machine, described removable medium 74 comprises disk (comprising flexible disk), CD (comprising CD-ROM (compact disk ROM (read-only memory)) and DVD (digital universal disc)), magneto-optic disk, semiconductor memory etc.If necessary, use the wired or wireless communication medium,, carry out that program is installed on the program recorded medium by as communication unit 59 such as the router of interface, modulator-demodular unit etc. such as LAN (Local Area Network), Internet, digital satellite broadcasting etc.

Should be noted that in this manual the step of describing the program on the program recorded medium that is stored in not only comprises the processing of carrying out with the sequential of described order, and comprise processing parallel or independent and that needn't carry out chronologically.

In this manual, system refers to as device or Circuits System by a plurality of equipment or circuit-formed integral body.

It will be understood by those of skill in the art that and to make various modifications, combination, sub-portfolio and replacement, as long as they are in the scope of claims or its equivalent according to designing requirement and other factors.
