Abstract
The utility model discloses a scanning projection equipment which can repeatedly play multi-page images, comprising a scanner, a master computer and a projector. The scanner scans a plurality of documents one by one; the original image signals from the scanner are received one by one and processed by the master computer; then the processed final image signals are stored one by one into the master computer. The final image signals are received in sequence and projected on the screen by the projector. The master computer can receive the choosing signal from users and export a final image signal on the signal source which is corresponding to the choosing signal to the projector for projection display according to the choosing signal.
Description
Technical field
The invention relates to a kind of scanning projection device, especially about a kind of can scanning, the scanning projection device of processing and repeat playing multi-page pictures.
Background technology
The mode of existing making PowerPoint will be printed as transparency with briefing material by duplicating machine, more printed transparency is placed on the projector, with projector briefing material is incident upon on the screen.Such processing mode can consume a large amount of transparencys, and a large amount of uses of transparency also can cause the problem of environmental protection.On the other hand, make at needs under the situation of colour projection film, spent cost is very high.
Though have the digital projector that can be connected to computing machine the data of computing machine can be projected on the screen, when the user does not have electronic document, just can't directly finish projection work by digital projector.
Another kind of existing method referring to No. 413419 communique of Republic of China's patent, discloses a kind of common paper part that can directly utilize above and has come the scanning projection device of projection.But, in this patent gazette,, can only handle the picture signal of one page owing to be subjected to the restriction of structure of its hardware and software at every turn, and can't repeat playing the picture signal crossed of scan process.Such as when making PowerPoint, can alternately play the picture of associated usually, and the scheme in this patent gazette just can't be finished this function.
In addition, in this patent, the connector of projector can be scanned instrument and take, when the user will use common paper and computer document to carry out the manuscript demonstration simultaneously, he must switch the signal source of projector for scanner or computing machine, causes the inconvenience in the use.
Therefore, but how to provide a kind of repeat playing multi-page pictures, and the scanning projection device in changeable signal source, be the problem to be solved in the present invention.
Summary of the invention
In view of this, but one object of the present invention just is to provide a kind of scanning projection device of repeat playing multi-page pictures.Another object of the present invention just provides the scanning projection device in a kind of changeable signal source.
For achieving the above object, but the invention provides a kind of scanning projection device of repeat playing multi-page pictures, wherein comprise a scanner, a principal computer and a projector.Scanner is used for scanning a plurality of files one by one, and exports many original image signals.Principal computer receives and handles this original image signal from this scanner one by one, produces many final image signals, and is stored in the principal computer.Projector receives this final image signal from principal computer one by one, and this final image signal is projected on the screen.Principal computer can receive the selection signal that the user provides, thereby according to selecting signal, a final image signal on the corresponding signal source is outputed on this projector for Projection Display.
The user can come input select signal by the software interface that is presented at the software interface on the main computer screen or be presented on the projection screen, and activates scanning projection device and carry out the scanning projection action.

Fig. 2 is the synoptic diagram of the scanning projection device in the embodiments of the invention two;
Fig. 3 is the synoptic diagram of the scanning projection device in the embodiments of the invention three.
Embodiment
Below in conjunction with specific embodiment the present invention is carried out further detailed introduction, Fig. 1 is the synoptic diagram of the scanning projection device in the embodiments of the invention one.As shown in Figure 1, the scanning projection device in the present embodiment comprises a scanner 10, a principal computer 20 and a projector 30.Scanner 10 scans a plurality of files one by one, and exports many original image signal SO.Scanner 10 can be general falt bed scanner, paper feeding scanner or in conjunction with the multifunction scanner of automatic paper conveying apparatus.
For instance, the user is the scanning projection sheet on one side, Yi Bian carry out the playback action of transparency.When needs are play the image of before having broadcast, can carry out choosing of image by the software interface that is presented on the screen 40 as selected cell 26.In addition, the user can also activate scanning projection device by button on the scanner or software interface.
Fig. 2 is the synoptic diagram of the scanning projection device of the embodiment of the invention two.As shown in Figure 2, scanner 10 is sent to principal computer 20 with original image signal SO, and principal computer 20 is processed into final image signal SF with original image signal SO and sends it to projector 30 for exporting screen 40 to.When needs were play the image of before having broadcast, the user can carry out choosing of image by the software interface that is presented on the display 23 as selected cell 26.
Fig. 3 is the synoptic diagram of scanning projection device in the embodiments of the invention three.As shown in Figure 3, the scanning projection device of present embodiment, wherein scanner 10 comprises 15, one receivers 17 of a telepilot.Receiver 17 is contained on the housing 11, is used for receiving from the selection signal of telepilot 15 and with it outputing to selected cell 26.Telepilot 15 can be carried by the user, and is provided with a group selection button 16, is used for exporting under user's operation selecting signal.Therefore, the user only needs a folded file is put on the automatic paper conveying apparatus 12 when playing projected picture, and action subsequently only gets final product with telepilot 15 controls.
Therefore, scanning projection device of the present invention can scan first file earlier for Projection Display.Also during the content at first file of explanation, the time of scanner utilization redundancy is scanned second file again, also can continue to scan the 3rd and later file the user.Like this, after not needing to wait until the All Files been scanned, just the image projection that will play can be come out.And the user also can utilize selected cell to select the scanned image that will play easily.In traditional scanning projection device, if will play the picture of having play, also need the file that will will play run-down again, this is unusual inconvenience concerning the user.Scanning projection device of the present invention can address this is that, and the scanning projection device of a kind of more facility and hommization is provided.
Moreover, the connector of the projector among the present invention can not be scanned instrument and take, if the user will use common paper and computer document to carry out PowerPoint simultaneously, he do not need with projector the signal source switch back and forth at scanner or intercomputer, therefore use quite facility.
The above embodiments only are used to further specify technology contents of the present invention and scheme; and unrestricted protection scope of the present invention; in the situation that does not exceed claim under the spirit of the present invention, and the embodiment of the many variations of being done, protection scope of the present invention all belonged to.
