Based on above-mentioned, the later stage develops and another kind of scan mode, and it is in the process that motor retreats, doing scanning is in the lump also stored, then relatively motor stops to move the image information of gained when before and after moving back, with the point that obtains coincideing the most, and as the image junction point.
Yet, because this technology when movement images information, is the image information of file more to be scanned, thus high when repeated if the image information of file to be scanned has, just be easy to generate the joint mistake.
Summary of the invention
In view of above problem, of the present invention mainly is in order to a kind of image joint method to be provided, to use the document image information of avoiding scanning gained to be scanned that the overlapping or the phenomenon of dialysis are arranged.
Therefore, for reaching above-mentioned purpose, the disclosed image joint method of the present invention be to be applied to the image information that image reading apparatus scans file to be scanned, and with its scanning process that is passed to terminating machine, the method includes the following step:
When the insufficient space of image reading apparatus during with store images information again, photosensory assembly group self-scanning speed is slowed down stopping scanning, and the acquisition encoding strip is at the image of this stop position.Afterwards, make the photosensory assembly group retreat the counter-rotating distance, and the counter-rotating distance is greater than the required acceleration distance of photosensory assembly group.And the space for the treatment of image reading apparatus is when being cleared, and the photosensory assembly group is quickened until sweep speed, and scan image information and in one acquisition period, the image of acquisition encoding strip.Then, compare the image of the encoding strip of front and back time acquisition by image reading apparatus, and obtain the image junction point.According to the image junction point, the image information of time scanning before and after engaging, and the image information of continuation scanning file to be scanned are until finishing scanning again.
Therefore, the encoding strip that the present invention can be captured by the matrix photosensory assembly is proceeded the scanning of the image information of file to be scanned, and the image information that does not have a file to be scanned has and overlaps or the phenomenon of dialysis.
