Method for automatically converting format of scanned image file and computer program product

The present invention relates to a file format conversion method, and more particularly to a method for automatically performing an image processing program on a scanned image file and converting the scanned image file into a format. The invention also relates to a computer program product for automatically converting a scanned image file format, comprising a set of computer code, which can be executed when a computer loads the computer code.

After the scanning is completed, the conventional scanning device will only display the scanned image file on the connected computer or display. If the user wants to convert the format of the file, it is necessary to open the file conversion application and then manually convert it one by one, which is quite time consuming and inconvenient.

[Fig. 1] A flow chart showing a method of a conventional scan and conversion format. As shown in step 101, the user sets the file to a predetermined storage location.

Next, as shown in step 102, the scanning device scans a file.

Then, as shown in step 103, after the scanning is completed, the scanning device transmits the scanned image file to the connected computer and displays it on the computer.

Next, as shown in step 104, the user manually opens the file conversion application.

Then, as shown in step 105, in the file conversion application, the user selects the file obtained by the previous scan and sets the format and file storage location to be converted.

Finally, as shown in step 106, the user obtains the file to be converted by the file conversion application.

If the user wants to transfer multiple scanned image files, it takes a lot of time to manually Repeating steps 105 and 106 is quite inconvenient.

On the other hand, if the user wants to copy the text portion of the paper document, the scanning file device with the optical character recognition (OCR) function is generally used to scan the paper file for obtaining, for example, .rtf or searchable PDF. Wait for an electronic file in text format for subsequent editing.

FIG. 2 is a flow chart of a scanning method with an OCR function scanning device. As shown in step 201, the user sets the file to the predetermined storage location.

Next, as shown in step 202, the scanning device performs an OCR scan on a file. The OCR scan performs optical character recognition conversion for the scanning device while scanning.

Finally, as shown in step 203, the scanning device generates an archive having a textual format.

The user selects the OCR scan in advance, that is, no manual conversion is required, and the disadvantage is that it is limited by the data calculation, transmission capability and scanning speed of the scanning device. If you scan a copy of the same file, the OCR scan takes more time than a normal scan. In other words, the user does not need to manually shift files, but still needs to spend extra time waiting for the scanning device to generate a scan file. For users with multiple files to be scanned, direct OCR scanning is not fast.

Therefore, the purpose of the method of the present invention is to save the user the time wasted by repeatedly shifting the file manually or waiting for the OCR scan to generate the file, thereby increasing work efficiency.

The invention provides a method for scanning an image file automatic conversion format. First, it is determined whether there is a scanned image file to be converted, such as whether there is a scanned image file on the data storage device, or whether a scanned image file is received, and then an image processing program is automatically performed to convert the scanned image file into a format and replace it.

Therefore, the present invention provides a method for automatically converting a scanned image file, comprising the following steps: a determining step of determining whether there is a scanned image file to be converted; and a converting step of automatically converting the scanned image file when the scanned image file is scanned The format. According to the present invention, there is also provided a computer program product comprising a computer program code, wherein when a computer loads the computer code, the steps of the above method can be performed.

It is better to use the image processing and conversion file format on the computer. Even if the scanning device does not have the OCR function, the user does not need to do any manual shifting operation and does not need to wait for a long time to obtain the text format. File or other format file. Conversion to a file in text format is for the convenience of the user for subsequent editing. The user can also set a file to be converted into another format.

By using the method of the present invention, the converted file can be directly stored in the computer location or network designated by the user, and can directly replace the original scanned image file in the data storage device of the scanning device. If the original image type file such as .bmp, .jpeg or image PDF is obtained by scanning, after the conversion method of the present invention, a file with a text format such as .txt, .rtf or searchable PDF can be obtained and replaced.

In order to make the above description of the present invention more comprehensible, the following detailed description of the preferred embodiments and the accompanying drawings will be described below.
