In step 600, method 100 only in storer 24 without any when storing the storage space of this JPEG or this RunLength formatted data, just repeatedly with image acquisition module 12 these raw videos of acquisition, and and then print the duplicate of this raw video.In other words, when method 100 can still have the remaining data storage space of this JPEG of storage or this RunLength formatted data in storer 24, this JPEG or this RunLength formatted data are stored in the storer 24 in advance, (save the step of image acquisition module 12 these raw videos of acquisition with the printing speed of accelerating reprographic system 10, as previously mentioned, a reprographic system often far surpasses the time of printing this image in the time that acquisition one image and handling is spent on this image).
In step 600, method 100 is differentiated the storage space whether these jpeg format data (step 610) of storage and this RunLength formatted data (step 622) are still arranged in the storer 24 in regular turn, successively to print the duplicate of this JPEG pattern image and this RunLength pattern image.In other words, in determining storer 24, there is not unnecessary storage space when storing these jpeg format data, method 100 is execution in step 601,602,604 and 610 in regular turn constantly, whether be printed up to the duplicate of all these JPEG pattern images and finish, just can then differentiate still has unnecessary storage space to store this RunLength formatted data in the storer 24.Because the required storage space of these jpeg format data is much larger than the required storage space of this RunLength formatted data, in other words, storer 24 smoothly these jpeg format data of storage and with this jpeg format data importing in this JPEG decoding path with the probability of the duplicate of printing this JPEG pattern image by part ground much smaller than storer 24 these RunLength formatted datas of storage and this RunLength formatted data is directed in this RunLength decoding path with the probability by the duplicate of this RunLength pattern image of part ground printing smoothly, therefore, in order to increase the printing effect of image system 10, method 100 is also optionally differentiated the storage space whether this RunLength formatted data of storage is still arranged in the storer 24 earlier, duplicate with this RunLength pattern image of first line printing, and after the total printing of the duplicate of this RunLength pattern image finishes, just differentiate the storage space whether these jpeg format data of storage are still arranged in the storer 24, to print the duplicate of this JPEG pattern image.
See also Fig. 9, Fig. 9 is the process flow diagram of a step 650 in the method 100, the alternative step 600 of step 650.In step 650, the storage space whether this RunLength formatted data of storage and these jpeg format data are still arranged in the storer 24 is differentiated on method 100 as above-mentioned ground in regular turn, just successively prints the duplicate of this RunLength pattern image and this JPEG pattern image according to this.Step 650 comprises the following step:
Step 651: capture this raw video, and convert this raw video to a gray level image;
Step 652: this gray level image is imported this direct outgoing route, this JPEG coding path and this RunLength coding path;
Step 654: whether the duplicate that differentiation image output device 20 is printed is the duplicate of last a RunLength image pattern, if, carry out step 670, otherwise, carry out step 660;
Step 660: differentiate the storage space that whether still has this RunLength formatted data of storage in the storer 24,, then carry out step 662 if having, otherwise, carry out step 651;
Step 662: this RunLength formatted data is stored in the storer 24;
Step 664: the RunLength formatted data that will be stored in the storer 24 is directed in this RunLength decoding path;
Step 666: whether the umber of the duplicate of the RunLength image pattern that differentiation image output device 20 is printed equals the umber of the duplicate of this RunLength image pattern in this control data, if, carry out step 670, otherwise, carry out step 664;
Step 670: whether the duplicate that differentiation image output device 20 is printed is the duplicate of last a JPEG image pattern, if, carry out step 999, otherwise, carry out step 672;
Step 672: differentiate the storage space that whether still has these jpeg format data of storage in the storer 24,, then carry out step 674 if having, otherwise, carry out step 651;
(at this moment, with regard in the storer 24 if do not stored with regard to the storage space of these jpeg format data, even if stored this RunLength formatted data in the storer 24, method 100 also can because of the RunLength formatted datas that are stored in the storer 24 can't be for the usefulness of the duplicate of printing this JPEG pattern image, and need return to step 651 again to capture this raw video)
Step 674: with this jpeg format data storage to storer 24;
Step 676: the jpeg format data importing that will be stored in the storer 24 is deciphered the path in this JPEG;
Step 678: whether the umber of the duplicate of the JPEG image pattern that differentiation image output device 20 is printed equals the umber of the duplicate of this JPEG image pattern in this control data, if, carry out step 999, otherwise, carry out step 676.
Certainly, with regard to step 600, method 100 can not have the storage space of these jpeg format data of storage yet in differentiating storer 24 after, the footpath row is differentiated the storage space that whether has this RunLength formatted data of storage in the storer 24, and after printing finishes the duplicate of this RunLength pattern image, capture this raw video more again to print the duplicate of this JPEG pattern image.
Step 700 and step 800 are similar in appearance to step 600 (or step 650), that is step 700 and 800 is formed at JPEG shown in the step 600 (high storage space) and RunLength (low storage space) are replaced to JBIG respectively, so repeat no more in this.
See also Figure 10 to 12, Figure 10 to 12 is the process flow diagram of step 900 in the method 100.The principle that step 900 not only can be followed in the step 600 to be showed, differentiate in regular turn and whether still have storage this JPEG (high storage space) in the storer 24, the storage space of this JBIG (middle storage space) and this RunLength formatted data (low storage space), again according to discrimination result, with this JPEG, this JBIG and/or this RunLength formatted data are stored in the storer 24, the principle that step 900 also can be followed in the step 650 to be showed, differentiate in regular turn and whether still have this RunLength of storage in the storer 24, the storage space of this JBIG and these jpeg format data, again according to discrimination result, with this RunLength, this JBIG and/or this jpeg format data storage are in storer 24, to accelerate the printing speed of reprographic system 10.Yet, owing to the duplicate of this JBIG pattern image can be finished by the mode that will be stored in this JPEG decoding path of jpeg format data importing in the storer 24, as the step 632 in the step 600, so shown step 900 is optionally controlled the shadow tone image that compressor reducer 22 do not exported error diffusion module 16 and is compressed into a JBIG formatted data among Figure 10.Step 900 comprises the following step:
Step 901: capture this raw video, and convert this raw video to a gray level image;
Step 902: this gray level image is imported this direct outgoing route, this JPEG coding path and this RunLength coding path;
Step 904: whether the duplicate that differentiation image output device 20 is printed is the duplicate of last a JPEG image pattern, if, carry out step 920, otherwise, carry out step 906;
Step 906: differentiate the storage space that whether still has these jpeg format data of storage in the storer 24,, then carry out step 908 if having, otherwise, carry out step 901;
Step 908: with this jpeg format data storage to storer 24;
Step 910: the jpeg format data importing that will be stored in the storer 24 is deciphered the path in this JPEG;
Step 912: whether the umber of the duplicate of the JPEG image pattern that differentiation image output device 20 is printed equals the umber of the duplicate of this JPEG image pattern in this control data, if, carry out step 914, otherwise, carry out step 910;
(processor 30 will be stored in jpeg format data importing in the storer 24 constantly to this JPEG decoding path, till the umber of the duplicate of the JPEG image pattern that image output device 20 is printed equals the umber of the duplicate of this JPEG image pattern in this control data)
Step 914: whether the duplicate that differentiation image output device 20 is printed is the duplicate of last a JBIG image pattern, if, carry out step 920, otherwise, carry out step 916;
Step 916: stored this jpeg format data in the differentiation storer 24, if, carry out step 917, otherwise, carry out step 901;
Step 917: the jpeg format data importing that will be stored in the storer 24 is deciphered the path in this JPEG;
(owing to stored this jpeg format data in the storer 24, the duplicate of remaining JBIG pattern image can be finished to this JPEG decoding path by the jpeg format data importing that will be stored in the storer 24)
Step 918: whether the umber of the duplicate of the JBIG image pattern that differentiation image output device 20 is printed equals the umber of the duplicate of this JBIG image pattern in this control data, if, carry out step 920, otherwise, carry out step 917;
Step 920: whether the duplicate that differentiation image output device 20 is printed is the duplicate of last a RunLength image pattern, if, carry out step 999, otherwise, carry out step 922;
Step 922: differentiate the storage space that whether still has this RunLength formatted data of storage in the storer 24,, then carry out step 924 if having, otherwise, carry out step 930;
Step 924: this RunLength formatted data is stored in the storer 24;
(method 100 is carried out so far, represent to have in the storer 24 enough in order to storing the storage space of this RunLength formatted data, and processor 30 can be stored to this RunLength formatted data in the storer 24)
Step 926: the RunLength formatted data that will be stored in the storer 24 is directed in this RunLength decoding path;
Step 928: whether the umber of the duplicate of the RunLength image pattern that differentiation image output device 20 is printed equals the umber of the duplicate of this RunLength image pattern in this control data, if, carry out step 999, otherwise, carry out step 926;
(the RunLength formatted datas that processor 30 will be stored in the storer 24 constantly are directed into this RunLength decoding path, till the umber of the duplicate of the RunLength image pattern that image output device 20 is printed equals the umber of the duplicate of this RunLength image pattern in this control data)
Step 930: differentiate in the storer 24 whether stored these jpeg format data? if, carry out step 932, otherwise, carry out step 901;
Step 932: the jpeg format data importing that will be stored in the storer 24 is deciphered the path in this JPEG; And
Though (do not had unnecessary storage space in the storer 24 to store this RunLength formatted data, but owing to stored this jpeg format data in the storer 24, the duplicate of remaining RunLength pattern image can be finished to this JPEG decoding path by the jpeg format data importing that will be stored in the storer 24)
Step 934: whether the umber of the duplicate of the RunLength image pattern that differentiation image output device 20 is printed equals the umber of the duplicate of this RunLength image pattern in this control data, if, carry out step 999, otherwise, carry out step 932.
Certainly, shown step 900 is optionally controlled the shadow tone image that compressor reducer 22 exported error diffusion module 16 and is compressed into a JBIG formatted data among Figure 10, be not compressed into a RunLength formatted data and will not describe the printable image that control module 18 exported, can be directed into this JPEG and this JBIG decoding path respectively and finish by being stored in JPEG in the storer 24 or JBIG formatted data as for the duplicate of the RunLength pattern image of remainder, because this similar process is in step 900, so repeat no more in this.In addition, step 900 is also optionally differentiated the storage space whether this JBIG formatted data of storage (middle storage space) is still arranged in the storer 24 earlier, duplicate with this JBIG pattern image of first line printing, and after the total printing of the duplicate of this JBIG pattern image finishes, just differentiate the storage space whether storage this JPEG (or this RunLength) formatted data is still arranged in the storer 24, to print the duplicate of this JPEG (or this RunLength) pattern image.Differentiate earlier and just differentiate storer 24 behind the storage space whether storer 24 still have this JBIG formatted data of storage and whether still have the similar process of storage space of these jpeg format data of storage in step 650 (hanging down storage space → high storage space), just differentiate storer 24 behind the storage space whether storer 24 still have this JBIG formatted data of storage and whether still have the similar process of storage space of this RunLength formatted data of storage and differentiate earlier in step 600 (high storage space → hang down storage space), so repeat no more in this.
Compared to known reprographic system, reprographic system of the present invention according to the storage size of a storer and be input on the control panel control data comprised corresponding to the kind of the pattern of the duplicate quantity of a raw video and this duplicate, use an image processing module, one error diffusion module, one describes the gray level image that control module and a compressor reducer change this raw video converts a JPEG earlier to, one JBIG and a RunLength formatted data, and and then with this JPEG, after this JBIG and this RunLength formatted data are stored in this storer, just will be stored in the JPEG in this storer, JBIG and RunLength formatted data are directed in a JPEG respectively, one JBIG and RunLength decoding path is with a JPEG, the duplicate of one JBIG and a RunLength pattern image prints on an image output device.Since storer still have enough storage spaces with the situation of storing a JPEG, a JBIG or a RunLength formatted data under, reprographic system of the present invention only needs by capturing this raw video once, just can print the duplicate of all these raw videos, so reprographic system of the present invention has preferable printing effect.In addition, reprographic system of the present invention only is additional to a compressor reducer and a decompressor in the known reprographic system, so the structure of reprographic system of the present invention is quite simple.
