Description

How to set quality / resolution on your fax {METHOD FOR SETTING RESOLUTION / IMAGE QUALITY IN A FACSIMILE}

The present invention relates to a facsimile, and more particularly, to a method for setting image quality / resolution in a facsimile for setting image quality / resolution of an original.

In general, when transmitting image data or copying an original using a facsimile, it is possible to change or set different image quality or resolution for each page, and to transmit or copy. In the conventional method of changing and setting different image quality, resolution, etc. for each page, the image quality / resolution can be changed and set during transmission or copying of the page immediately preceding the page for which the image quality / resolution is to be changed. As an example of such a general image quality / resolution setting method, a user selects a document transmission function to set image quality / resolution. Then, when you press the start transmit key, the fax reads the original at the image quality / resolution set by the user and sends it. If the user wants to change the image quality / resolution for a specific page, the user changes the image quality / resolution on the previous page of the specific page that the user wants to change. The facsimile then read and transmitted the image with the changed image quality / resolution. In other words, if you want to send the 1st and 2nd pages in normal mode, the 3rd page in fine mode, and the 4th page in normal mode again, first read the document. On the screen and select Normal mode to start sending originals. The facsimile then reads the original in the set normal mode and transmits the original placed on the reading unit. When the transmission of the first page is completed and the second page is being transmitted, the user changes the resolution of the third page to the fine mode in order to transmit the third page in the fine mode. Then, after the completion of the transmission of the second page and before the transmission of the third page, the third page is transmitted by changing the resolution to fine mode by the protocol exchange of the facsimile transceiver. The protocol execution process according to the image quality / resolution information communication is described in the patent application 94-11789. If the resolution is set to normal mode during the third page transmission in order to change the image quality / resolution of the fourth page, the fourth page is transmitted in the normal mode after the third page transmission by the protocol exchange of the transmitting / receiving side. When a plurality of pages are transmitted as described above, when the quality or resolution of an intermediate page is to be changed, the quality or resolution may be changed in the page immediately before the desired page. Image quality / resolution setting when copying an original can also be set in a similar manner to the image quality / resolution setting when sending an original. In recent years, however, it is very difficult to change the desired image quality or resolution during document transmission or copying, as the fast read function is adopted in the fax. Because originals are first read, stored in memory, and then image data is sent or copied, it is difficult to change the image quality or resolution during high-speed data transfer. In particular, changes in image quality and resolution during manuscript transmission or copying will become more difficult.

As described above, when changing the image quality or resolution of some pages during original transmission or copying with the conventional fax, the image quality or resolution of the page to be changed can be changed from the previous page. As a result of this problem, it is difficult to change image quality or resolution during image data transmission or copying.

Another problem is that in order to change the image quality or the resolution of a document transmission or copying, there is a problem that a person must wait until the page to be changed.

SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide a page for changing image quality or resolution and a method of presetting image quality / resolution before image data transmission or copying starts.

Another object of the present invention is to set the page and the image quality / resolution to change the resolution in advance before the start of image data transmission or copying to eliminate the inconvenience that the personnel must wait to change the image quality and resolution during document transmission or copying It also provides a way to set the resolution.

In order to achieve the above object, the present invention provides a method for setting an image quality / resolution in a facsimile, and sets the image quality / resolution of the document in advance for each page before document transmission or document copying and performs document transmission or copying.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a facsimile,

The central processing unit 10 controls the overall operation of the facsimile according to the set program, and controls the overall operation according to the image quality / resolution setting and change during image data transmission or copying. The memory unit 12 stores telephone numbers and image data, and stores various operation programs. OPE (OPERATING PANEL) 14 has a plurality of function keys, original transmission mode key, image quality / resolution setting key, copy mode key, and applies key data according to the pressing of the key to the central processing unit 10. And an operation state displayed under the control of the central processing unit 10. When the document is supplied, the scanner 16 reads the document, converts the image of the document into digital image data, and applies it to the central processing unit 10. The modem 18 performs analog modulation on the transmission data under the control of the CPU 10 and demodulates the analog reception data. The LIU (LINE INTERFACE UNIT) 20 is operated under the control of the central processing unit 10 to form a call loop of the telephone line, and interfaces the signal of the modem 18 with the signal of the telephone line. The printer unit 22 prints image data on a recording sheet under the control of the central processing unit 10.

2A, 2B and 2C are control flow diagrams for setting the image quality / resolution of an original to be transmitted or copied in a facsimile according to an embodiment of the present invention. After setting, when sending originals or copying originals, image data is read and transmitted or copied at the image quality / resolution set by page.

Therefore, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2A, 2B, and 2C.

Referring to Figure 2a, 2b, 2c how to set the image quality / resolution in the facsimile according to the present invention, in step 101 the central processing unit 10 loads the original placed on the document glass to the reader Then proceed to step 102. In step 102, the central processing unit 10 sets a standardized quality / resolution that is commonly applied to the entire document. The standard definition / resolution setting may be input by the user through the image quality / resolution setting key of the OPE 14, and the standard quality / resolution may be specified in advance in the facsimile. For example, image quality and resolution can be differentiated according to the model of the facsimile, but generally the image quality divided into normal, photo, dark, light, and normal The resolution can be divided into fine (fine) and super-fine (fine). In addition, among the divided image quality / resolution, the user may manually set the image quality / resolution to be applied to the entire document, and may specify a standardized quality / resolution commonly applied in advance. Thereafter, in step 103, the CPU 10 checks whether there is a page to change the image quality / resolution. The page to be inspected for change can be checked by sending a message through the display device of the OPE 14 and receiving a key input for the page to be changed through the OPE 14 from the user. In step 103, if there is no page to change the image quality / resolution, the process proceeds to step 107. In step 104, the central processing unit 10 receives a page to be changed from the user through the keypad of the OPE 14. Thereafter, in step 105, the CPU 10 receives and sets the image quality / resolution of the change request page input by the user through the image quality / resolution setting key of the OPE 14 from the user. Then, in step 106, the central processing unit 10 checks whether the setting of the page inputted from the user is completed and proceeds to step 107 if the setting is completed, and returns to step 104 if the setting is not completed. Will be rerun. In step 107, if all settings of the page of the original loaded in the image quality / resolution settings are checked, and if the whole setting is completed, proceed to step 108; if the whole setting is not completed, go back to step 103. The image quality / resolution setting for the page to be changed is repeated until step 107. In step 108, the CPU 10 stores the image quality / resolution setting for each page in a storage area of the memory unit 12, and then proceeds to step 109. In step 109, the central processing unit 10 checks whether the original transmission mode is selected by the user through the OPE 14, and proceeds to step 110 if the original transmission mode is selected, and if the original transmission mode is not selected, 122 Proceed to step. In step 110, the central processing unit 10 controls the memory unit 12 to search for information on the image quality / resolution set on the first page of the original to be transmitted, and then proceeds to step 111. In step 111, the central processing unit 10 communicates the receiving side facsimile and the protocol with respect to the image quality / resolution of the first page set. The time point at which the image quality / resolution information is transmitted / received to the transmitting / receiving side facsimile during protocol communication becomes phase B of the protocol. Thereafter, the central processing unit 10 controls the scanner 16 to read the image data at the image quality / resolution set on the first page, and then proceeds to step 113. In step 113, the CPU 10 controls the modem 18 and the LIU 20 to transmit image data for the first page to the receiving side fax. Then, in step 114, the central processing unit 10 checks whether the transmission of the image data of the first page, which is the current page, is completed, and proceeds to step 115 if the current page transmission is completed. The process continues until the image data transmission for the page is completed. In step 115, the central processing unit 10 checks whether the transmitted page is the last page. If the page is the last page, the central processing unit 10 terminates the original transmission. In step 116, the central processing unit 10 controls the memory unit 12 to retrieve the setting information of the image quality / resolution set on the next page, and then proceeds to step 117. In step 117, the CPU 10 checks whether the settings of the image quality / resolution found in step 116 have changed, and if there is a change in image quality / resolution, proceeds to step 118; Proceed. In step 118, the CPU 10 performs a protocol with the receiving side facsimile on the signal for the changed picture quality / resolution. Thereafter, the central processing unit 10 controls the scanner 16 to read the image data at the changed image quality / resolution in step 119, and then proceeds to step 120. In step 120, the CPU 10 controls the modem 18 and the LIU 20 to transmit image data of the page read in step 119 to the receiving side fax. Then, in step 121, the central processing unit 10 checks whether image data transmission has been completed for the current page. If the current page transmission is not completed, the CPU 10 returns to step 120 and continues until image data transmission for the current page is completed. If the transmission of the current page is completed, the process returns to step 115 and sequentially performs steps 116 to 121 until image data transmission to the last page is completed, and then ends when the last page is transmitted. If the document transmission mode is not selected in step 109, the process proceeds to step 122. In step 122, the central processing unit 10 checks whether the copy mode is selected, and if the copy mode is selected, proceeds to step 123 and does not select it. If so, the program according to the present invention is terminated. In step 123, the central processing unit 10 controls the memory unit 12 to search for information on the image quality / resolution set on the first page of the original to be copied, and then proceeds to step 124. In step 124, the central processing unit 10 controls the scanner 16 to read image data at the image quality / resolution set on the first page, and then proceeds to step 125. In step 125, the central processing unit 10 controls the printer 22 to copy the image data for the first page read. Then, in step 126, the central processing unit 10 checks whether the copy of the image data of the first page, which is the current page, is completed, and proceeds to step 127 when the copy of the current page is completed. It continues until the copy of the image data for the page is completed. In step 127, the central processing unit 10 checks whether the copied page is the last page, and if it is the last page, finishes copying the original, and if it is not the last page, proceeds to step 128. In step 128, the CPU 10 controls the memory unit 12 to retrieve the setting information of the image quality / resolution set on the next page, and then proceeds to step 129. In step 129, the CPU 10 checks whether the settings of the image quality / resolution found in step 128 have been changed, and if there is a change in image quality / resolution, proceeds to step 130; Proceed. In step 130, the central processing unit 10 controls the scanner 16 to read the image data at the changed image quality / resolution, and then proceeds to step 131. In step 131, the CPU 10 controls the printer 22 to copy image data of the page read in step 130. Then, in step 132, the central processing unit 10 checks whether image data has been copied for the current page, and if the copy of the current page has not been completed, returns to step 131 and continues until the image data for the current page has been copied. If the copy of the current page is completed, the process returns to step 127 to sequentially perform steps 128 to 132 until the copy of the image data is completed to the last page, and then ends when the last page is copied. That is, in the image quality / resolution setting method according to the present invention, after receiving the image quality / resolution setting information for each page from the user in advance before the original transmission or the original copy function is performed, the central processing unit 10 starts the original transmission or the original copy. Reads and transmits and copies the image data according to the image quality / resolution which is sequentially set from the first page to the last page.
