Explain the details of projecting cell 220 now with reference to Fig. 3 and Fig. 4.Fig. 3 shows the figure of amplification of the optical system of projecting cell 220.Fig. 4 shows the figure of the optical system of the Fig. 3 that sees from the left side, has wherein omitted projection optical system 221.

The optical system of projecting cell 220 is constructed to its bottom surface and is approximately the foursquare four prism type module of about 10mm * 10mm (being called module hereinafter).The length direction of this module is oriented in vertical direction, and the bottom surface of this module (being lower surface) be joined together by the base 15 (referring to Fig. 1) of the metal main body 11 with high-termal conductivity.It should be understood that in Fig. 3 and 4 understand internal structure according to these figure easilier in order to make, the size of described quadrangular is illustrated as longer than its actual size at its length direction.

This module comprises White LED 223 (LED substrate 230), light-gathering optics 227, Polarizer 225, PBS (polarization beam apparatus) piece 226, liquid crystal panel 222 and projection optical system 221.In this structure, among above-mentioned member, all members except projection optical system 221 all are integrated in the mould component 231.Specifically, LED substrate 230 is arranged on the under shed surface element office of the member of making by bending thin plate made of aluminum 231.LED substrate 230 is made into aluminium sheet, and the wiring pattern on the insulating barrier that is formed on this substrate realizes it being the LED 223 of photocell.

In addition, light-gathering optics 227 and PBS piece 226 are adhered to mould component 231.PBS piece 226 is polarising beam splitters, wherein divides 226a to be sandwiched between two triangular prisms with respect to the polarization separation section at incident light axis angle at 45.Surperficial 226b to this PBS piece 226 carries out non-reflection processing, and for example melanism is handled etc.

Downside (its surface on light-gathering optics 224 1 sides) at PBS piece 226 arranges Polarizer 225.And the upside of PBS piece 226 is provided with the liquid crystal panel 222 that is made of reflection type liquid crystal cell (LCOS).

Base 15 constitutes the framework of main body 11.The surface of the surface of base 15 and LED substrate 230 is joined together in order to conduct heat from generating component (in the present embodiment for LED substrate 30) well.Specifically, the filler material that thermal conductivity is high is filled between the surface and LED substrate 30 of base 15, and perhaps the heat conduction containment member is sandwiched between them.By forming this high-efficiency heat conduction path, can suppress the rising of the temperature of projecting cell 220.

Utilize the module of said structure, drive current is supplied to LED 223 on the LED substrate 230 via not shown wire harness and wiring pattern from projection control circuit 224.LED 223 is towards the light of light-gathering optics 227 emissions corresponding to the brightness of drive current.Light-gathering optics 224 makes LED light approximate parallel, and guides it to be incident on the Polarizer 225.Polarizer 225 is linearly polarized photon with this incident light conversion (or expansion), and will change (or expansion) polarised light afterwards towards 226 emissions of PBS piece.

Be incident on polarised light flux (for example P polarised light) the process PBS piece 226 on the PBS piece 226 and illuminate liquid crystal panel 222.Liquid crystal panel 222 is made of a plurality of picture elements, and on described picture elements, it is driven in order to create color image to be formed with redness, green and blue filter and described filter.When the light of the liquid crystal layer that passes through liquid crystal panel 222 is incident on the liquid crystal panel 222, direction that makes progress in Fig. 3 moves on by this liquid crystal layer for it, and after the reflecting surface of liquid crystal panel 222 is reflected, move on and send from liquid crystal panel 222 by the downward direction of liquid crystal layer in Fig. 3, will be incident on the second time on the PBS piece 226.Because liquid crystal layer serves as phase-plate when being applied in voltage, so be incident on the PBS piece 226 this for the second time only as the light modulated of S polarised light and mixing as the unmodulated light of P polarised light.PBS piece 226 utilizes polarization separation section to divide 226a only to reflect in (bending) this luminous flux the light modulated of incident for the second time, and this light modulated is the S polarized light component, and towards projection optical system 221 these components of emission in the left side of figure as projected light.

The main processing

Below, explain the flow process of printing with reference to the flow chart of Fig. 5.Fig. 5 shows the flow chart of this example of mainly handling of being undertaken by CPU 101.The processing of Fig. 5 begins when the main switch of printer 10 is switched on.

In the step S51 of Fig. 5, CPU 101 carries out model selection, and Kong Zhi flow process proceeds to step S52 then.This printer 10 has rest image printing model and dynamic image printing model.If with indication rest image pattern, then CPU 101 arranges the rest image pattern from actuation member 103 input actuated signals, if import actuated signal to indicate mobile image model, then it arranges mobile image model.Be understood that will the operator scheme that will use of indication information placement be in the Exif information that is recorded in the image file and according to the pattern that the information of this record is identified for that image file is operated also to be acceptable.In this case, will not need for the actuating of selecting and arrange the operator scheme that will be employed from rest image pattern and dynamic image pattern.

The rest image pattern

To explain the situation when the rest image pattern is set now.In step S52, CPU 101 impels projecting cell 220 for being stored in by from each static picture document (for example its extension name is designated as the file of the form of " .JPG ") the projection thumbnail image in the file of the actuated signal indication of actuation member 103 (this file is defined within the storage card 150, wherein stored in the memory 102 of the data that send from external equipment or in the hard disk drive (HDD)); Then, control flow proceeds to step S53.Specifically, CPU 101 reads for the data of these thumbnail images and in the presumptive area of memory 102 these data is launched, and after this launched, along with these data are sent to projection control circuit 224, its indication projection control circuit 224 carried out projection to it.

Fig. 7 shows the figure of the example that is projected in the image on the printing paper 14 that is loaded in the lid 12.In Fig. 7, a plurality of thumbnail images are projected under the situation that is arranged to a row.If there are nine thumbnail images or more, then in nine thumbnail images each, switch the page that (change over) is being projected.CPU 101 is at the cursor (the thick frame among Fig. 7) that is superimposed upon by the indicated position projection of actuated signal from actuation member 103 (for example can be the cross key) on the thumbnail image.Be understood that nine that are not limited to provide by example by the number of the thumbnail image of while projection; This number can be four images or 20 images.

When importing the actuated signal of the projection of indicating next image from actuation member 103, CPU 101 switches to by the image that is projected shown in the example among Fig. 8.According to Fig. 8, be projected as amplification corresponding to the thumbnail image of any one static picture document.CPU 101 is corresponding to from the actuated signal of actuation member 103 (for example cross key) and switch the thumbnail image that is being projected in order.And when importing the actuated signal of the projection of indicating nine images on the single screen from actuation member 103, then CPU 101 becomes again by the image that is projected shown in the example among Fig. 7 for the second time.

In step S53, CPU 101 judges that the selection about whether having carried out original image activates.If imported the actuated signal from actuation member 103 (for example can be OK button), then CPU 101 makes sure judgement and control flow proceeds to step S54 in step S53, if and not from OK button input actuated signal, then to make in step S53 negate to judge and control flow proceeds to S59 to CPU 101.

In step S54, CPU 101 utilizes projecting cell 220 to come the selected image of projection, and control flow proceeds to step S55 then.Specifically, if the image that is projected just shown in the example in perspective view 7 then at the time point from OK button input actuated signal, is taken as selected image with original image, described original image is corresponding to the thumbnail image of the current cursor that superposeed on it.In addition, if just in projection by the image that is projected shown in the example among Fig. 8, then at the time point from OK button input actuated signal, the original image of image file is taken as selected image, described image file is corresponding to the thumbnail image that is projected.CPU 101 reads selected image, in other words, namely be taken as the raw image data with the printed image object, and in the presumptive area in memory 102 it is launched, and, along with the data after will launching send to projection control circuit 224, also indicate projection control circuit 224 to carry out its projection.

Fig. 9 shows the figure of the example that is projected in the image on the printing paper 14 that is loaded in the lid 12.In Fig. 9, show the frame (frame) 91 of printing paper size and show that the frame 92 of print range all is included in the content of projection, and the size of images that is projected is controlled as less than stamp with the size.101 pairs of projection control circuits of CPU 224 are specified projection conditions, in order to create the print conditions that print unit 120 using (tone of the size of the paper that is for example using, printer enlargement ratio, print position (the blank surplus limit on the printing paper), print colors, printing strong or weak etc.) again in the image that is projected.It should be understood that in the print conditions that carries out with the image that is projected is created again, be arranged as only create again among the above-mentioned project be instructed to those also be acceptable.

Received following signal if print control circuit 123, described signal indication printing paper 14 is not loaded in the lid 12, perhaps there be presenting unusually of printing paper 14, or the decline of ink surplus etc., then CPU 101 impels the projection control circuit 224 projections information warning relevant with printing to replace or covers selected image.This information warning that is included in the image that is projected can be message or mark.

In step S55, CPU 101 judges the actuating of whether having carried out revising print conditions.If from actuation member 103 (for example MENU button) input actuated signal, then CPU 101 obtains sure judgement and control flow proceeds to step S56 in step S55, if and not from MENU button input actuated signal, then CPU 101 judgement and the control flow that obtain negating in step S55 forwards step S57 to.

In step S56, CPU 101 according to from the MENU actuated signal of actuation member 103 to printing the change information that control circuit 123 sends print conditions, then, control flow proceeds to step S57.It should be understood that in step S55 under the situation for negative judgement, will be useless to printing control circuit 123 such transmission information, will use the default print condition because print control circuit 123.

In step S57, CPU 101 judges whether carried out the print command actuating.If imported actuated signal from actuation member 103 (for example OK button), then CPU 101 obtains sure judgement and control flow proceeds to step S58 in this step S57, if and not from OK button input actuated signal, then to obtain in this step S57 negate to judge and control flow turns back to step S51 to CPU 101.

In step S58, CPU 101 prints processing, and then, control flow proceeds to step S59.The details of this print processing will be described below.In step S59, CPU 101 judges whether indicated termination.If be used to indicate the actuated signal of termination from actuation member 103 inputs, then CPU 101 processing that obtains sure judgement and Fig. 5 in this step S59 is terminated, if and be not used to indicate the actuated signal of termination from actuation member 103 input, then CPU101 obtains the judgement negating in this step S59, and control flow turns back to step S51.

Print processing

Explain the details of the print processing during the rest image pattern now with reference to example flow diagram shown in Figure 6.In the step S61 of Fig. 6, CPU 101 indications are printed control circuit 123 and are begun to print, and then, control flow proceeds to step S62.Specifically, CPU 101 is sent in the raw image data that launches in the presumptive area of memory 102 as selected image to printing control circuit 123.

In step S62, CPU 101 indication projection control circuit 224 projection black images (initial optical image), then, control flow proceeds to step S63.Thus, set up following state, wherein by the image that is projected shown in the example among Fig. 9 by temporarily shielding (blackedout), and do not comprise any type information (such as selected image).It should be understood that some colors (for example blue) except black of projection also are acceptables.In step S63, the lastrow of the selected image of CPU 101 order projection control circuit 224 projections, then, control flow proceeds to step S64.The projection width of this delegation is controlled as and is approximately equal to the print span that is printed on the delegation on the printing paper 14 by print unit 120.

In step S64, CPU 101 judges whether the printing of delegation is finished.If from printing the completed signal of printing of control circuit 123 input indication delegation, then CPU 101 obtains sure judgement in this step S64, and control flow proceeds to step S65, if and the completed signal of printing of input expression delegation, then CPU 101 obtains negative judgement in this step S64, and repeats this determination processing.

In step S65, CPU 101 order projection control circuit 224 also carries out the projection of next line for the selected image that is projected, and then, control flow proceeds to step S66.Thus, the type information that is included in the image (selected image) that is projected is broadened delegation.

In step S66, CPU 101 carries out about whether completed judgement of the printing of delegation.If from printing the completed signal of printing of the described next line of control circuit 123 input indications, then CPU 101 obtains sure judgement in this step S66, and control flow proceeds to step S67, if and the completed signal of printing of input indication delegation, then CPU 101 obtains the judgement negating in this step S66, and repeats this determination processing.

In step S67, CPU 101 carries out all the capable judgements that whether are projected about selected image.If be projected (in other words from projection control circuit 224 all row of input indication, all type informations are included in the image that is projected) signal, then CPU 101 obtains sure judgement in this step S67, and control flow proceeds to step S68, if and input does not show the signal that all row are projected, then CPU 101 obtains the judgement negating in this step S67, and control flow turns back to step S65.

Figure 10 shows the figure of the example of the image that is projected of once being widened delegation.The print speed that is included in selected image in the image that is projected and print unit 120 synchronously begins once to be broadened delegation from its lastrow, and therefore the scope of selected image is widened gradually.Along with this of scope of selected image widened, be included in occlusion area BK in the image that is projected by constriction gradually.

In the step S68 of Fig. 6, CPU 101 carries out about whether having finished the judgement of printing.Control circuit 123 all row of input expression all are printed and the completed signal of discharge of the paper 14 of printing paper if from printing, then CPU 101 obtains sure judgement in this step S68, and indication projection control circuit 224 stops projection (namely cutting out LED 223), then, the processing of Fig. 6 stops.On the other hand, if input expression has stopped printings of all row and finished the signal of the discharge of printing paper, then CPU 101 obtains the judgement negating in this step S68, and repeats this determination processing.

The dynamic image pattern

To explain the situation of dynamic image pattern now.In the step S52 of Fig. 5, CPU 101 impels projecting cell 220 projective representations to constitute each the representative image (for example leading (leading) image) of a plurality of frames in the dynamic image relevant with dynamic image file (for example its expansion is called the file of the form of " .MOV "), described dynamic image file is stored in the file of having indicated from the actuated signal of actuation member 103 and (and is defined within the storage card 150, wherein stored in the memory 102 of the data that send from external equipment, or in the hard disk drive (HDD) 106).

Figure 11 shows the figure of the example that is projected in the image on the printing paper 14 that is loaded in the lid 12.In Figure 11, the representative image of a plurality of mobile image files is projected arranging under the situation in a row.If there are nine representative image (in other words, i.e. dynamic image file) or more, then for per nine images, switch the page that is being projected.CPU 101 is at the cursor (the thick frame among Figure 11) that is superimposed upon by the indicated position projection of actuated signal from actuation member 103 (for example can be the cross key) on the representative image.It also is acceptable that the number of the representative image that is projected simultaneously is not limited to nine.

In the mode under the situation that is similar to the rest image pattern, when importing the actuated signal of the projection of specifying next image from actuation member 103, CPU 101 switches to and the image that similarly is projected shown in Fig. 8.In other words, can amplify also projection corresponding to the representative image of any one dynamic image file.In this case, corresponding to the actuated signal from actuation member 103 (for example cross key), CPU 101 switches the representative image that is being projected in order.And when importing the actuated signal of the projection of indicating nine images on the single screen from actuation member 103, then CPU 101 becomes again by the image that is projected shown in the example among Figure 11 for the second time.

In this dynamic image pattern, CPU 101 indication printers 120 are printed the representative image of this selected dynamic image file in the operation of reproducing (projection) selected dynamic image file with projecting cell 220.

Figure 12 shows at the figure that is projected in the example of the image on the printing paper 14 among the step S54 at Fig. 5 during the dynamic image pattern.In Figure 12, show that the frame of the size of printing paper all is included in the project content with the frame that shows print range, and the size of images that is projected is controlled as less than stamp with the size.CPU 101 to projection control circuit 224 indication projection conditions in case in the image that is projected, create again print unit 120 employed print conditions (for example use paper size, print enlargement ratio, print position (the blank surplus limit on the printing paper), the tone of print colors, intensity of print colors etc.).During this that it should be understood that print conditions in the image that is projected is created again, only create again among the above-mentioned project indicated those also be acceptable.

Print processing

Explain the details of the print processing of dynamic image pattern now with reference to the example flow diagram shown in Figure 13.

Among the step S71 in Figure 13, the dynamic image that 224 beginnings of CPU 101 indication projection control circuits have been chosen as the dynamic image file of printing (projection) object reproduces, and then, control flow proceeds to step S72.Specifically, CPU 101 sends the two field picture that constitutes the dynamic image file in the presumptive area that is stored in order in the memory 102 according to the order since the view data of first frame frame rate of per second 30 frames (for example with) to projection control circuit 224 successively.Thus, projecting cell 220 carries out the dynamic image reproduction since first frame successively.

In step S72, CPU 101 indications are printed control circuit 123 and are printed representative image, and then, control flow proceeds to step S73.Specifically, CPU 101 is to printing the data representing image that control circuit 123 sends in the presumptive area that is stored in memory 102.

At step S73, CPU 101 carries out reproducing the judgement that whether has finished about dynamic image.If the completed signal of projection from projection control circuit 224 input expression last frames, then CPU 101 obtains sure judgement and control flow proceeds to step S74 in this step S73, if and the completed signal of projection of input expression last frame, then CPU 101 obtains the judgement negating in this step S73, and repeats above determination processing.

In step S74, CPU 101 carries out about whether having finished the judgement of printing.If imported from printing control circuit 123 that the expression representative image is printed and the completed signal of discharge of printing paper 14, then CPU 101 obtains sure judgement and the 224 termination projections (namely closing LED 223) of indication projection control circuit in this step S74, then, the processing of Figure 13 stops.On the other hand, if input expression is printed and has been terminated and the completed signal of discharge of printing paper, then CPU 101 obtains the judgement negating in this step S74, and repeats above determination processing.

According to aforesaid first embodiment, can obtain following favourable operating effect.

(1) print unit 120 and projecting cell 220 are provided for printer 10, and its to be arranged in that print unit 120 begins to print will be that to come projection via projecting cell before the image of the object that is printed will be this image (in step S54) of the object that is printed.Thus, the operator can determine whether to impel printer 100 to print under the situation of the details of confirming to want printed image (being about to is the image of the object printed) in advance according to the big image that is projected.

(2) projecting cell 220 will not be image projection for the object of printing at the printing paper 14 that is being printed, but be projected on the lid 12 (or being loaded on wherein the printing paper 14).By the surface of carrying out projection thereon with its on the surface that printing be different, so during not only can and printing (this is certain) before the printing of printer 120 and after printing, continue to carry out projection by projecting cell 220.In addition, because the color of printing paper 14 white normally so compare with the situation of projection on the surface of different colours, is confirmed tone easily.

(3) since the image that is projected by the lid projection towards a part of main body that constitutes printer 10, so do not need to provide any special-purpose projection screen.In addition, because lid 12 is arranged to rotate to its deposit position (referring to Fig. 1 (b)) around the rotating shaft O as axle (axis), therefore can lid 12 be deposited in the mode of compactness.

(4) owing to be controlled as scope less than the printing by print unit 120 by the size of images of projecting cell 220 projections, will drop on outside the actual size of printing paper 14 so needn't worry projected image.

(5) because the frame (frame) that is arranged as the frame (frame) of the scope that shows printing paper 14 and shows the print range of print unit 120 all is included in the optical imagery by projecting cell 220 projections, print surplus limit so can check the blank on the image that is projected in advance.

(6) since control by the projection condition of the image of projecting cell 220 projections in order to create print unit 120 employed print conditions (size of the paper that is using, print the tone of enlargement ratio, print position, print colors and print intensity) again, so can check print image (printing situation) at the image that is projected in advance.

(7) during print unit 120 prints, be arranged as the optical imagery (for example image of wherein widening gradually as the scope of the image of the object of printing that is projected) of the state of the progress of show printing from projecting cell 220 projections (at step S62 to S67).Thus, the operator can understand the state of the progress of printing according to this image that is projected.

(8) can apply control, thereby after during print unit 120 is carried out printing, after the image that is projected of projecting cell 220 projections has been printed beginning, temporarily having been covered, subsequently, progress along with the printing of print unit 120, finish the printing of delegation at every turn, widen the scope that is used for the image of the object printed from the conduct of projecting cell 220 projections with regard to delegation ground.As a result, can show in real time what degree printing has proceeded to.

(9) owing to when finishing by the printing of print unit 120, apply control to stop the projection by projecting cell 220, therefore be used for to understand printing reliably and when finish.

(10) owing to being arranged as the information warning that during print unit 120 is carried out printing, from the image of projecting cell 220 projections, comprises the following degradation of presenting unusual or ink surplus of expression printing paper 14, so unusual generation can be informed the user immediately.

(11) print unit 120 and projecting cell 220 are included in the printer 10, and are arranged as and impel print unit 120 to print (in step S52 to S58) image from just being instructed to by projecting cell 220 among a plurality of thumbnail images of projection.Thus, the operator can be in that check will be as the image of the object that is used for printing by indication in a plurality of images of large scale projection.

(12) owing to be arranged as and make projecting cell 220 projections use a plurality of thumbnail images of multiple series of images data reproduction in a row, so can indicate in a lump when checking a plurality of images that are being projected with large scale will be as the image of the object of printing for the operator.

(13) owing to be arranged as the size of a plurality of thumbnail images that make projecting cell 220 increase use multiple series of images data reproductions, and next image ground carries out projection in order, so the operator can indication will be as the image of the object of printing when checking the image that is projected with large scale in order.

(14) owing to provide hard disk drive (HDD) 106 to printer 10, and be arranged as and projecting cell 220 projections used be accumulated in a plurality of thumbnail images that the view data on this hard disk drive is reproduced, so the operator can will be as the image of the object that is used for printing from indication among the great amount of images.

(15) owing to be arranged as the view data of having printed in the past at hard disk drive (HDD) 106 accumulation printers 10, so can print for the second time in simple mode, and eliminate the requirement of when wanting print image data, view data being read in printer 10 from the outside at every turn.

(16) owing to be arranged as that receive to be used for will be as the indication of the image of the object of printing by indicating from the actuated signal of actuation member 103, thus the operator can be in order will be as the image of the object of printer 10 printings by activating described actuation member 103 direct indications when checking the image that is projected with large scale.

(17) this printer 10 that comprises print unit 120 and projecting cell 220 has dynamic image printing model and rest image printing model, wherein printer 10 is printed and the image of projection dynamic image file in the dynamic image printing model, and printer 10 is printed or the image of projection static picture document in the rest image printing model, and printer 10 is arranged to according to selected printing model and controls print unit 120 and projecting cell 220.Thus, output image by rights, no matter it is rest image or dynamic image.

(18) if printer 10 is automatically selected the dynamic image printing model when being arranged as the image that comprises the object that has been indicated as printing in dynamic image file, if printer 10 is automatically selected the rest image printing model when perhaps comprising the image of the object that has been indicated as printing in static picture document.Thus, can make and do not need to carry out for according to selecting any actuating of printing model as the image of the object of printing.

(19) because under the situation of dynamic image printing model, projecting cell 220 reproduction projections have been indicated as the dynamic image as the image of the object of printing, so can export this dynamic image as the image that is projected.In addition, because print unit 120 is printed the representative image that has been indicated as the dynamic image of the image of the object of printing, so the frame that can export dynamic image is as printed image.

(20) owing to be arranged as and make print unit 120 begin afterwards to print receiving print command (the sure judgement among the step S57), so do not begin print processing during still at the image that inspection is projected as the operator.

Alternate embodiment #1

The flow chart of Fig. 5 is following flow diagram, and it shows, and select will be as the image that is used for printing when next image ground, and the example of the handling process when printing by the image of next image ground selection.As an alternative, be arranged as that to carry out printing together as the selection of the image of the object of be used for printing and the described a plurality of images that will select like this together to a plurality of images also be acceptable.

Alternate embodiment #2

Under the situation of rest image pattern, be arranged as that also to carry out following operation except aforesaid operations also be acceptable.When in the model selection of step S51 is handled, when CPU 101 arranges the rest image pattern, further select rest image pattern #1 to the rest image pattern #3 any one and arrange according to the actuated signal from actuation member 103.

Rest image pattern #1 is reaching the pattern of operating under the pattern mentioned above shown in Fig. 5 and 6.Rest image pattern #2 carries out the pattern of not carrying out the projection of projecting cell 220 during the printing at print unit 120.Specifically, after indication printing control circuit 123 has begun to print in the step S61 of Fig. 6, the processing of CPU 101 skips steps S62 to S67, and impel projecting cell 220 to stop projection up in step S68, making the judgement that printing has finished.

Rest image pattern #3 is the operator scheme of carrying out so-called " lantern slide exhibition (slide show) " projection.Under this pattern, the image that CPU 101 impels projecting cell 220 to select with predetermined one next image ground, interval projection successively, and print without print unit 120.

Be understood that following layout also is acceptable, be about to specify the information of the operator scheme that will use to be recorded in the Exif information of image file, and be identified for the pattern of the operation of this image file according to the information of this record.In this case, can make and do not need to carry out for selecting among from rest image pattern #1 to rest image pattern #3 and the actuating of setting operation pattern.

According to this alternate embodiment #2, owing to the rest image printing model is divided into three kinds of different rest image pattern #1 to #3 and makes it possible to select in these patterns any one, so can select output mode to be used for selected image is output as the image that is projected or is output as printed image.

In rest image pattern #3, owing to come the selected image of projection one at a time by projecting cell 220, can make the image that only operator is needed be output as the image that is projected.

Alternate embodiment #3

Same under the situation of dynamic image pattern, be arranged as that also to carry out following operation except aforesaid operations also be acceptable.When CPU 101 arranges the dynamic image pattern in the model selection of step S51 is handled, further select dynamic image pattern #1 to the dynamic image pattern #3 any one and arrange according to the actuated signal from actuation member 103.

Dynamic image pattern #1 is reaching the pattern of operating under the pattern mentioned above shown in Fig. 5 and 13.Dynamic image pattern #2 be only by projecting cell 220 carry out selected dynamic image file reproduction (projection) operation and do not print the operator scheme of the printing of unit 120.Specifically, in Figure 13, skips steps S72 and S74, and only execution in step S71 and S73.

Dynamic image pattern #3 is following operator scheme, wherein in the operation of the reproduction (projection) of carrying out selected dynamic image file with projecting cell 220 according to the print command (from the actuated signal of actuation member 103) of this dynamic image reproduction period impel print unit 120 print before the time point that generates actuated signals and the frame of afterwards predetermined number in each image.

Now will be in the details with reference to this print processing during explaining dynamic image pattern #3 by the flow chart shown in the example among Figure 14.In the step S81 of Figure 14,224 beginnings of CPU 101 indication projection control circuits are reproduced as the dynamic image of the selected dynamic image file of the object of printing (projection), and then, control flow proceeds to step S82.Thus, projecting cell 220 reproduces since the first frame dynamic image in order.

In step S82, CPU 101 judges the printing of whether having indicated the frame of this dynamic image reproduction period.If imported actuated signal from actuation member 103, then CPU 101 obtains sure judgement in this step S82, and control flow proceeds to step S83, and if do not import this type of actuated signal, then in this step S82, obtain the judgement negating, and control flow forwards step S86 to.

In step S83, CPU 101 indications are printed control circuit 123 and are carried out the printing of the frame (for example eight frames) of predetermined number, and then, control flow proceeds to step S84.Specifically, CPU 101 in order to print control circuit 123 be sent in nearest (i.e. the projection) that launch in the presumptive area of memory 102 four frames view data and and then (be projection before) will be stored in the view data of four frames in the memory 102.Thus, print unit 120 is printed before the time point that sends frame print command (namely printing initiation command) and the image of four frames afterwards.

In step S84, CPU 101 carries out reproducing the judgement that whether has finished about dynamic image.If represent the signal that the projection of last frames finishes from 224 inputs of projection control circuit, then CPU 101 obtains sure judgement in this step S84, and control flow proceeds to step S85, if and the signal that the projection of last frame finishes is not represented in input, then in this step S84, obtain the judgement negating, and repeat above-mentioned determination processing.

In step S85, CPU 101 carries out about printing whether completed judgement.If printed the image of whole eight frames and the completed signal of discharge of printing paper 14 from printing control circuit 123 input expressions, then CPU 101 obtains sure judgement and the 224 termination projections (namely closing LED 223) of indication projection control circuit in this step S85, then, the processing of Figure 14 stops.On the other hand, print to finish and paper discharge termination signal if import this type of, then CPU 101 obtains the judgement negating in this step S85, and repeats above-mentioned determination processing.

In the step S86 that arrives via the negative judgement among the step S82, CPU 101 carries out reproducing completed judgement about dynamic image.If from the completed signal of projection of projection control circuit 224 input expression last frames, then CPU 101 obtains sure judgement and the 224 termination projections (namely closing LED 223) of indication projection control circuit in this step S86, and then, the processing of Figure 14 stops.Under the situation of not sending the frame print command, make the sure judgement among the step S86.Therefore, if the signal that stops of the projection of input expression last frame, then CPU 101 obtains the judgement negating in step S86, and control flow turns back to step S82 and this system wait frame print command.

According to this alternate embodiment #3, because the dynamic image printing model is divided into three kinds of different dynamic image pattern #1 to #3, and can select any one in these patterns, so can select output mode to be used to be output as the image that is projected or be output as printed image.

Under this dynamic image pattern #3, be arranged as and impel print unit 120 to print before the time point that sends the frame print command during the reproduction projections from the dynamic image of projecting cell 220 and whole eight frames afterwards.Therefore, can impel a plurality of printed images of output to comprise the montage of operator's needs.

Be understood that following layout also is acceptable, be about to specify the information of the operator scheme that will use to be recorded in the Exif information of image file and determine the operator scheme of this image file according to the information of this record.In this case, can make and do not need to carry out for selecting among from dynamic image model #1 to dynamic image pattern #3 and the actuating of setting operation pattern.

Alternate embodiment #4

In rest image pattern #1, according to the state of the printing by print unit 120, be arranged as a delegation ground and widen and be included in by the type information in the image of projecting cell 220 projections (selected image) (referring to Figure 10).On the contrary, following layout also is acceptable, and namely basis is included in by the type information in the image of projecting cell 220 projections (selected image) by delegation's ground constriction of state of the printing of print unit 120.In this case, when printing began at first, projecting cell 220 projections comprised the initial optical image of whole selected image.And, along with synchronously a delegation ground is in the mobile type information (selected image) that is included in the projected image of downward direction with the print speed of print unit 120, projecting cell 220 also begins a delegation ground from the top of the image that is projected and covers the image that is projected.Along with this movement of the regional BK of crested with widen, be included in type information (being selected image) in the image that is projected by constriction gradually.According to this alternate embodiment #4, on the one hand, the type information that is being projected (being selected image) shows as along with printing paper 14 is drawn in the main body 11 of printer, and on the other hand, the printing paper of having printed 14 is discharged in the output paper pallet 13 gradually.As a result, the operator can understand printing in real time and proceed to what degree, and the selected image that is being projected simultaneously is reduced to become the output that is printed.

Alternate embodiment #5

Be included in by the type information in the image of 220 projections of projecting cell (being selected image) except correspondingly changing with the printing of print unit 120 progress, be arranged as by making the type information (being selected image) that is included in the image that is projected flat or to tilt or amplify or dwindle additive effect also be acceptable.If print the required time period than scheduled time segment length, then change the image that is projected by additive effect, when informing that the operator prints required time segment length, also guarantee that at the reformed image that is projected the operator can not be sick of by just providing.

Alternate embodiment #6

Though having explained wherein comes electronic compensating by the example of the trapezoidal distortion of the image of projecting cell 220 projections by CPU 101, but following layout also is acceptable, is the shake that comes from the vibration that is caused by print unit 120 during printing and compensates the image that is projected electronically.Usually, printer 10 vibration along the direction mobile print head 122 of print line the time and when presenting printing paper 14.The image that CPU 101 compensation are projected is so that the vibration that is projected in the image on the printing paper 14 that inhibition causes owing to this vibration.Specifically, CPU 101 synchronously replaces coordinate information with the feed status of translational speed, its amount of movement, its moving direction and the printing paper 14 of printing head 122, and this coordinate information is illustrated in the position of the view data of launching in the presumptive area in the memory 102.Thus, dynamic image data electronically in storage space.The data for projection that vibration compensation during CPU 101 has printed it to projection control circuit 224 output is by this way handled, thus and suppress may be given by the vibrations of the image that is projected operator's any uncomfortable sensation.

Alternate embodiment #7

By using from Electrofax 100 rather than to carry out for the detection of selecting to activate as the selection of the image of the object of printing among thumbnail image (referring to Fig. 7) or representative image (referring to Figure 11) from the actuated signal of actuation member 103 also be acceptable.The Electrofax 100 of Fig. 2 is endowed function from menu switch to printer 10 that wirelessly transmit actuated signal from cross key or.The CPU 101 of printer 10 selects according to the actuated signal that receives via external interface (I/F) circuit 104 will be as the image of the object of printing.The operator carries Electrofax 100, and can be from select away from the position of printer 100 will be as the image of the object of printing.Be understood that actuated signal from Electrofax 100 to printer 10 this transmission also can transmit to realize by circuit.Therefore, because printer 10 can receive appointment by the actuated signal from Electrofax 100 will be as the order of the image of the object that is printed, so the operator can will be as the image of the object that is printed from the position indication away from printer 10 by the actuation member of actuating electronic camera 100 when checking the image that is being projected with large scale in order.

Embodiment 2

Structure that printer wherein is endowed the function that catches image is provided and will also be acceptable as the detection of the actuating of the image of the object that is printed by using the image that is caught by printer to carry out for selecting.Figure 15 is the block diagram of structure that is equipped with the printer 10A of camera unit 320 for explanation.For with Fig. 2 in by structure identical in the block diagram shown in the example, additional identical Reference numeral, and omit its explanation.Here, except the control that prints unit 120 and projecting cell 220, CPU 101A also carries out the control of camera unit 320.

Camera unit 320 comprises picture catching optical system 331, imageing sensor 322 and picture catching control circuit 323, and catches image by projecting cell 220 projections according to the order from CPU 101A.Shown in Fig. 1 (a) and 1 (b), for example, can be adjacent to provide side by side picture catching optical system 321 and imageing sensor 322 with projecting cell 220.

Image is caught optical system 321 forms photograph object (in this example, be projected on the printing paper 14 that is loaded in the lid 12 image) in the image capture surface of imageing sensor 322 image.Can use CCD or cmos image sensor etc. as imageing sensor 322.Picture catching control circuit 323 is together with according to from the order of CPU 101A and the driving of control chart image-position sensor 322 also utilizes internal image change detecting circuit (not shown) to detect the variation of the image that catches.Specifically, for the image that be captured of predetermined interval (for example per second 15 frames) from imageing sensor 322 outputs, picture catching control circuit 323 judges that the existence of the difference in the view data between the continuous frame images does not in time still exist.

During the projection of thumbnail image (or representative image), the operator of this printer 10A can put into his hand the space between printing paper 14 and the projecting cell 220, and interrupts the luminous flux that a part is projected.Thus, because operator's hand is included in the two field picture of new seizure, so between this two field picture and former frame image, cause inconsistent (being image change).

Picture catching control circuit 323 is divided into a plurality of zones (need be should make thumbnail image corresponding to during the projection) with the image that catches, and, for the zone (being called " block ") of each division, carry out inconsistent whether greater than the judgement of predetermined value about between latest frame image and the former frame image.And if picture catching control circuit 323 detects the inconsistent block that surpasses predetermined value between the frame, then it checks whether this state continues more than or equal to for example 0.5 second.And, if for detected block, picture catching control circuit 323 has judged that (in other words the variation of the seizure image in the same block at least eight successive frames is taking place thereafter constantly, if for same block, in 0.5 second or longer time, capture the image of operator's hand constantly), then picture catching control circuit 323 judges that this is to be instructed to the image that prints, and therefore sends the signal of this block of expression to CPU 101A.

When receiving the signal of this block of expression, CPU 101A will be to the image that is projected of projection control circuit 224 indication (in the example shown in Fig. 7, it is a plurality of images) with from the signal correction connection of picture catching control circuit 323 transmission, and detect will be as the image of the object that is printed.For example, if from the lower-left block on the signal of the picture catching control circuit 323 indication projection screen, then CPU 101A gets thumbnail image (or representative image) that projecting cell 220 is prompted to be projected in the lower-left as selected image.

On the other hand, if for the detected block of picture catching control circuit 323, judged that seven variations in the continuous same block between the frame have in turn stopped taking place (in other words, if before 0.5 second past time, in same block, do not capture the image of operator's hand), then picture catching control circuit 323 judges that this is not that be instructed to will printed image, and does not therefore send any signal to CPU 101A.

According to above-mentioned second embodiment, obtain following favourable operating effect.

(1) camera unit 320 is included in to incorporate into has among the printer of projecting cell 220 10A, and catches image by projecting cell 220 projections by camera unit 320 with predetermined interval.And printer 10A detects owing to hand is included in the image change that takes place in the two field picture that is caught by camera unit 320, and judges that having carried out image selects to activate.Thus, the operator can be when checking the image that is projected hand by putting into him so that the luminous flux of its interception projection (and taken a picture by camera unit 320) and give an order to this printer 10A.

(2) this printer 10A is from projecting cell 220 optical imagery of a plurality of thumbnail images of projection in a row, will be wherein as the block that detects image change as described in (1) be associated with the image that is projected, and get the thumbnail image conduct that is projected in corresponding to the position of detected block will be as the image of the object that is printed.And the operator can use he need print among a plurality of thumbnail images that are projected image as the vision datum mark with as the standard in the space of the hand of putting into him.In addition, be that unit comes detected image to change owing to be arranged as with the block, so compare with the situation that the whole zone of image is detected, can reduce amount of calculation.

(3) because if in detecting block, continued in 0.5 second or longer time seizure image in one's hands etc., then picture catching control circuit 323 judges that an image has been designated as the object that is printed, even therefore operator error ground is placed on camera unit 320 fronts with his hand, do not make unwanted wrong judgement immediately.

Alternate embodiment #8

Be arranged as and utilize the combination be unkitted the printer 10 of being furnished with any camera unit 320 and Electrofax 100 to select to activate in the mode that is similar to second embodiment that to detect also be acceptable.Figure 16 is the block diagram for the structure of explaining printer system in this case.Cable links together via external interface circuit 104 for printer 10 and Electrofax 100.
