Abstract
The method of reducing scanning time for image includes the following steps: setting scanning parameters for each image, classifying image in appropriate method, setting the same scanning area for images of the same classification, and scanning. The said method makes it possible to complete scanning in least scanning path and least scanning time.
Description
The present invention relates to a kind ofly can carry out method for scanning, and be particularly related to a kind of method for reducing scanning time for images many images.
Usually scanner all is to carry out the action of scan-image according to step motor driven sweep head when scanning.Please refer to Fig. 1, is that known step motor driven sweep 102 is to carry out the action of many image scans.Wherein, on scanning platform, be placed with many images of A to G, when these images need scan, scanner head 102 is driven when reference position scans down, and at first can sweep to the end points line a of image A earlier, continues to scan the bottom line c of image A again, but in the process of scan-image A, can sweep to the end points line b of image B earlier, so after waiting image A to sweep, step motor just can drive the scanner head 102 scan-image B that goes back.
So go round and begin again, to all images all till the been scanned, wherein, a plurality of directions of arrow on Fig. 1 left side promptly are all courses that step motor drives scanner head 102 scan-image A～G.
Therefore can find that known technology is when many images of scanning, if there is the content of many images to include the part section of same sweep trace, the part section that all includes same sweep trace as the content of image A and image B, then when scanning, step motor can drive and later scan the B image again after scanner head 102 has scanned the A image earlier, and the content of image B and image C also includes the part section of same sweep trace, be with after having scanned the B image, step motor can drive scanner head 102 again and later scan the C image.
In this scan period, step motor must drive scanner head 102 and repeat course back and forth many times, and known technology has clearly been wasted many times on many images of scanning.
In view of this, purpose of the present invention is providing a kind of method for reducing scanning time for images exactly, the problem of wasting sweep time to improve known scan method.
For reaching above-mentioned purpose, the present invention proposes the time that a kind of method method for reducing scanning time for images reduces scanning, and the method comprises the following steps:
In pre-inswept journey, to each image setting sweep parameter, with optimal sorting technique classification image, then with similar image setting at identical scanning area, just begin afterwards to scan.
Wherein, above-mentioned sorting technique comprises following sorting technique: the image classification that presentation content is included the part section of same sweep trace is same class; To be same class at a default image classification that stops sweeping within the number of times scope; With those image classifications in same resolving range is same class; Setting those image classifications according to the user is same class.
Wherein, can also can image be classified, so that scanning motion can be finished with minimum path with a kind of classification image of classifying with more than one sorting technique.
In brief, the present invention utilizes scanning motion to begin previewing scan before, many images will doing scanning are done classification according to sorting technique, make its step motor scan all images and reduce and come flyback action repeatedly with minimum course, even can once finish the scanning route, and must not carry out scanning motion by commute, to reach the purpose that reduces by many image scan times.
For above and other objects of the present invention, feature and advantage can be become apparent more, preferred embodiment cited below particularly, and conjunction with figs. elaborate:

Embodiment:
Please refer to Fig. 2, is the flow chart of steps of the inventive method.Method of the present invention comprises the following steps: at first to choose the image that will scan in pre-inswept journey, the sweep parameter (step 202) of setting of image then, and wherein, sweep parameter comprises the resolution and the image data amount of image.Then according to sorting technique classification image (step 204), similar image in step 206, is set in same scanning area (step 206), afterwards, step motor can drive scanner head and begin to scan (step 208).Check then whether whole scanning areas has all scanned (step 210), begin to carry out scanning step (step 208) as if also having scanning area scanning as yet, then getting back to.If when whole scanning areas has all been swept, then separate the image (step 212) in the scanning area, finish scanning motion.
Please refer to Fig. 3, is above-mentioned sorting technique classification image (step 204) and with similar image setting more detailed step in same scanning area (step 206).At first choose first image and be comparison scanning area (step 302), take off an image then and compare (step 304), check whether this image and comparison scanning area have the part section (step 306) of same scanning area with the comparison scanning area.If have, then be combined into new comparison scanning area, reexamine and whether also have image not choose (step 314) as yet.If do not have, will not comprise that then the comparison scanning area of this image is made as scanning area (step 310), whether getting this image then is new comparison scanning area (step 312), reexamine to also have image not choose (step 314) as yet.
As if also having image not choose as yet, then rebound is taken off an image and is compared scanning area and compares (step 304), if whole images are all chosen finishes, and the action of setting scanning area then finishes to classify.
Illustrate among above-mentioned steps 204 and the step 206 actual steps performed with image subarea.In this example, the part section of supposing whether to have with presentation content same sweep trace is a sorting technique.Wherein, the part section whether so-called content according to image has same sweep trace to be meant the image more than 2 or 2 as sorting technique whether same sweep trace is arranged by these images when scanning, if have, can say that then these images include the part section of same sweep trace.
Please merge with reference to Fig. 3, Fig. 4, suppose in this example, the part section that whether has same sweep trace with presentation content is a sorting technique, and has images such as A, B, C, D, E, F, G to need the Using such method classification in Fig. 4.At first choose first image, as image A, as comparison scanning area (step 302); Take off an image then, the formed comparison scanning area of image B and image A compare (step 304); Then be checked through this image and compare the part section (step 306) that scanning area has same sweep trace, then image A and image B can be merged into new comparison scanning area (step 308); Whether have image do not choose, as image C (step 314), then get back to step 304 if reexamining still, judge whether the formed new comparison scanning area of image C and image A and image B has the part section (step 306) of same sweep trace; If have, then can continue to be merged into new comparison scanning area (step 308), repeat above-mentioned steps, image A, image B, image C and image D as can be known, content between image all has the part section of same sweep trace in twos, can in step 310 image A, image B, image C and image D being merged into scanning area 402.
Above-mentioned image A, image B, image C and image D are merged into scanning area 402 before, carry out the judgement of step 306 earlier, judge and learn that image E and image A, image B, the formed comparison scanning area of image C, image D do not have the part section of same sweep trace, so can will not comprise in step 310 that just the comparison scanning area of image E is made as scanning area 402, in step 312, getting image E is new comparison scanning area then.
Repeating step 304 is to step 314, till all subregion finishes, can obtain image E and image F until all images in same scanning area 404, and image G is then alone in scanning area 406.
In the step 306 of the foregoing description, the present invention can judge that also the resolution of each image is whether within the equal resolution scope, the foundation of being used as the image of classifying is if the resolution that many images are arranged can be same scanning area with these image settings then in the equal resolution scope.
In the step 306 of the foregoing description, stopping after the present invention also can utilize image to merge swept number of times and whether stops sweeping the image of classifying within the number of times scope default, stopping sweeping within the number of times scope default if stopping after image merges swept number of times, can be same scanning area with image setting then.
Wherein, when step motor driven sweep head scans, data can be received in the image buffer, by the time after the image buffer is filled, step motor can stop drive actions, after the image buffer is data output, continue the driven sweep head again and carry out scanning motion, repeat this action, till the data of all scanning areas has all been swept.And so-calledly stop sweeping number of times, promptly be that the number of times that continues scanning after step motor stops again is and stops sweeping number of times.
Defaultly stop sweeping number of times and be used as a kind of of sorting technique and utilize, be meant in pre-inswept journey, calculate earlier the image that forms the comparison scanning area stop sweep number of times and whether stop sweeping in the scope of number of times default, if form the comparison scanning area image stop sweep number of times and stop sweeping in the scope of number of times default, then can be with the image setting that forms the comparison scanning area at same scanning area, otherwise then deny.
In the step 306 of the foregoing description, the present invention also can utilize the user to set the image of classifying, and is same scanning area with similar image setting, just according to user's hobby with image classified, subregion.
The sorting technique of the foregoing description have respectively according to the content of image whether include same sweep trace the part section, according to the resolution of image whether in same resolving range, according to image stop sweep number of times and whether defaultly stopping sweeping in the number of times, be used as sorting technique according to user's setting.But except above-mentioned can be judged with a kind of sorting technique, the sorting technique that also can use more than one is as The classification basis, the resolution that for example can utilize image whether in same resolving range and image stop sweep number of times and whether stop sweeping in the number of times default, two kinds of sorting techniques are used as the Rule of judgment of step 306.
Thus, image is behind classification of process sorting technique and subregion, can make step motor drive scanner head and sweep all images with minimum travel path, and needn't be back and forth repeatedly execution scanning motion, and learn by the foregoing description, such classification, partition method, not only make step motor drive scanner head and swept all images with minimum travel path, can also make step motor once promptly finish the scanning motion of all images, and must not drive the scanner head commute to scan.
In sum, the present invention have can reduce really scanning pattern and sweep time advantage.
Though the present invention is disclosed in preferred embodiment; but it is not in order to qualification the present invention, any personnel that are familiar with this technology, without departing from the spirit and scope of the present invention; can be used for a variety of modifications and variations, but protection scope of the present invention should be with being as the criterion that claims limit.
