DETAILED DESCRIPTION

The term “image forming apparatus” may refer any type of apparatus, such as a printer, a scanner, a fax machine, a multi-function printer (MFP), or a display, which can perform an image forming operation. An “operation performed by an image forming apparatus” may involve printing, copying, scanning, faxing, saving, transmission, or the like.

Examples of the present disclosure will be described in detail hereinafter with reference to the accompanying drawings so as to be easily implemented by one of ordinary skill in the art to which the present disclosure belongs. The present disclosure may, however, be embodied in many different forms and is not limited to the examples set forth herein.

FIG. 1 is a conceptual diagram for describing an operation of an image forming apparatus outputting a first printout including first data in a predefined format, which is convertible to form a certain image, and an operation of the image forming apparatus outputting a second printout reflecting a modification based on the first printout, according to an example of the present disclosure.

Referring to 110 in FIG. 1, an image forming apparatus 10 may receive a print request for a certain document 111 from an electronic device. The image forming apparatus 10 may obtain first data 113 corresponding to the certain document 111.

The image forming apparatus 10 may receive the first data 113 from the electronic device or extract the first data 113 from a scanned image of the certain document 111. At this time, the first data 113 may have a predefined format and may be used to form a certain image. The first data 113 may be machine language that can be read by a processor of the image forming apparatus 10.

The image forming apparatus 10 may generate a temporary image for the certain document 111 and generate a first image by combining the temporary image with the first data 113. The image forming apparatus 10 may output a first printout 112 of the first image. The first data 113 may be superposedly displayed on the first printout 112. For example, the first data 113 may be transparently displayed.

Referring to 120 in FIG. 1, the image forming apparatus 10 may output a second printout 121 further including certain content in addition to the first printout 112.

For example, the image forming apparatus 10 may obtain the first image by scanning the first printout 112. The image forming apparatus 10 may extract the first data 113 from the first image and obtain the first temporary image with the first data 113 removed.

The image forming apparatus 10 may obtain a second temporary image by adding modification data such as a telephone number information 122 to the first temporary image based on an input for adding the telephone number information 122 to the first temporary image. The image forming apparatus 10 may generate the second image by combining the second temporary image with second data 123 representing second information obtained by combining the extracted first data 113 and the modification data to reflect a modification that may include a history of modifications, e.g., history of addition of the telephone number information 122. The image forming apparatus 10 may output the second printout 121 of the second image. The second data 123 may be superposedly displayed on the second printout 121.

FIG. 2 is a flowchart of a method of operating an image forming apparatus to output a printout including data used to form a certain image, according to an example of the present disclosure.

Referring to FIG. 2, the image forming apparatus 10 may obtain first data in a predefined format, which is used to form a certain image, in operation 210.

For example, the first data may be composed of digital code. For example, the first data may be machine language that can be read by a processor of the image forming apparatus 10. The first data may be used for conversion into a certain image including at least one piece of text or at least one picture.

For example, the image forming apparatus 10 may receive a print request for a certain file from an external device or a copy request for a certain document through a user interface device of the image forming apparatus 10. In this case, the image forming apparatus 10 may obtain first data in a predefined format, which is used by being convertible to form a certain image, from the certain file or document.

The image forming apparatus 10 may convert the first data into the certain image as a first temporary image representing first information corresponding to the first data in operation 220.

For example, the image forming apparatus 10 may read the first data and obtain the first information corresponding to the first data. The first information may be represented by at least one piece of text or at least one picture. The image forming apparatus 10 may generate the first temporary image including the first information. For example, when the first data is original data of the certain document, file, or image, the first temporary image may be an original image.

The image forming apparatus 10 may check whether a modification has been performed on the first temporary image in operation 230. At this time, the modification may include a modification of the entire area of the first temporary image or a modification of a partial area of the first temporary image.

When the modification has not been performed on the first temporary image, the image forming apparatus 10 may output, as a first printout, a first image resulting from combining the first temporary image with the first data in operation 240. For example, the image forming apparatus 10 may obtain the first image having the first data superposed on the first temporary image and output the first image as the first printout.

For example, the first data may be transparently displayed on the first printout. The first data may be displayed in a certain size in a certain area of the first printout. The first data may be displayed in a margin of the first printout. The first data displayed on the first printout may be hard to be visually identified by a user.

When the modification has been performed on the first temporary image, the image forming apparatus 10 may output a second image, which results from combining a second temporary image resulting from modification of the first temporary image with second data corresponding to a history of the modification of the first temporary image, as a second printout in operation 250. A process of obtaining the second temporary image resulting from the modification of the first temporary image will be described with reference to FIG. 4.

For example, the history of modification of the first temporary image may include at least one of a history of modification from the first temporary image to the second temporary image and a history of modification from the original image of the first temporary image to the first temporary image.

In the same manner as the first data is displayed on the first printout, the second data may be transparently displayed on the second printout. The second data may be displayed in a certain size in a certain area of the second printout. The second data may be displayed in a margin of the second printout. Because the second data is included in the second printout, the image forming apparatus 10 may obtain the second data, which includes original data and a modification history, from the second printout and may modify the second printout based on the second data or output a corresponding printout at a certain time.

FIG. 3 is a flowchart of a method of operating an image forming apparatus to output a second printout, which results from modification of a first printout, based on the first printout, according to an example of the present disclosure.

The image forming apparatus 10 may obtain a first image, which results from scanning the first printout, in operation 310. For example, a scanner of the image forming apparatus 10 may scan the first printout and obtain the first image as the scan result.

The image forming apparatus 10 may obtain a first temporary image, which results from extracting first data in a predefined format from the first image, in operation 320. For example, the image forming apparatus 10 may extract the first data in a predefined format from the first image. The image forming apparatus 10 may read the first data and convert the first data into the first temporary image including first information.

The image forming apparatus 10 may obtain a second temporary image, which results from modification of the first temporary image, based on a first input for modifying an entire or a partial area of the first temporary image in operation 330. A process of obtaining the second temporary image resulting from the modification of the first temporary image will be described with reference to FIG. 4.

The image forming apparatus 10 may output a second image printable as a second printout, which is generated by combining the second temporary image with second data corresponding to a modification history of the first temporary image, in operation 340.

FIG. 4 is a flowchart of a method of operating an image forming apparatus to obtain a second temporary image, which results from modification of a first temporary image, based on a first input for modifying a certain region of the first temporary image, according to an example of the present disclosure.

The image forming apparatus 10 may receive the first input for modifying an entire or a partial area of the first temporary image in operation 420.

For example, the first input may be for modifying at least one selected from words in text and the size and color of the text in a certain area of the first temporary image.

For example, the first input may be for modifying the size or color of a picture in a certain area of the first temporary image or for entirely or partially changing the picture.

For example, the first input may request to delete a portion of the first temporary image other than a predefined format in a certain area.

For example, the first input may request to recover the first temporary image or a certain temporary image corresponding to a state before generation of the first temporary image. For example, the first input may request to recover an original image.

The image forming apparatus 10 may obtain the second temporary image, which results from modification of the first temporary image, based on first modified data in a predefined format in operation 430, wherein the first modified data is obtained from the first input.

For example, the image forming apparatus 10 may obtain the first modified data in the predefined format from the first input. When the first input is for modifying a letter in a certain area, the image forming apparatus 10 may obtain a modified letter as the first modified data in the predefined format. In detail, the image forming apparatus 10 may obtain digital code, by which the modified letter is expressed in machine language readable by a processor, as the first modified data.

For example, the image forming apparatus 10 may obtain second data by combining the first data with the first modified data. The second data may reflect a modification corresponding to the first input. For example, the image forming apparatus 10 may combine the first data with the first modified data based on a position corresponding to the first modified data in the first data and the place of the first modified data in a modification order.

The image forming apparatus 10 may convert the second data into the second temporary image, which results from modification of the entire or partial area of the first temporary image.

FIG. 5 is a diagram for describing a process of outputting an image, which results from combining a certain document with data in a predefined format corresponding to the certain document, when there is a request for printing of the certain document, according to an example of the present disclosure.

Referring to 510 in FIG. 5, the image forming apparatus 10 may receive a request for printing of a certain document 511. For example, the image forming apparatus 10 may receive a request for printing of the certain document 511 from a user's electronic device. When the image forming apparatus 10 outputs the certain document 511 as a first printout, the image forming apparatus 10 may generate a temporary image of the certain document 511 and output the first printout based on the temporary image. In this case, first data 512, which is used to generate the temporary image of the certain document 511, may have a predefined format. For example, the first data 512 may be composed of digital code. For example, the image forming apparatus 10 may receive the first data 512 for the certain document 511 from the user's electronic device.

Referring to 520 in FIG. 5, the image forming apparatus 10 may convert the first data 512 into a first temporary image 521. The first temporary image 521 may include first information about “Michael Kim”. In detail, the first information may include information about a name, age, and/or a picture.

Referring to 530 in FIG. 5, the image forming apparatus 10 may generate a first image 531 by combining the first temporary image 521 and the first data 512. For example, the image forming apparatus 10 may generate an image 532 representing the first data 512 and generate the first image 531 by combining the image 532 and the first temporary image 521.

FIG. 6 is a diagram for describing a process of obtaining a second temporary image based on first modified data obtained from a first input when the first input for modifying a certain region of a first temporary image is received, according to an example of the present disclosure.

Referring to 610 in FIG. 6, the image forming apparatus 10 may display a first temporary image 611 on a user interface device. At this time, the first temporary image 611 may be generated by reading and converting first data 631 into text or a picture.

For example, when the image forming apparatus 10 receives a request for printing a certain file from an external device, the image forming apparatus 10 may obtain the first data 631. In another example, the image forming apparatus 10 may obtain a first image by scanning a first printout including the first data 631 and extract the first data 631 from the first image. The image forming apparatus 10 may convert the first data 631 into the first temporary image 611 and display the first temporary image 611 on the user interface device.

Referring to 620 in FIG. 6, the image forming apparatus 10 may receive a first input for modifying an entire or a partial area of the first temporary image 611. At this time, modification may include a modification of the content of the first temporary image 611 and/or a modification of the form of the first temporary image 611. The modification of the content may include a change of all or part of existing text or an existing picture. The modification of the form may include a change of all or part of the form without a change in the content. For example, the modification of the form may include a modification of at least one selected from font, size, thickness, and color of text displayed in the first temporary image 611.

For example, the image forming apparatus 10 may receive at least one of an input for modifying at least one selected from words, size, and color of text in a certain area of the first temporary image 611, an input for modifying size or color of a picture in the certain area, and an input for changing all or part of the picture.

Although not shown in the image 620 in FIG. 6, the image forming apparatus 10 may receive an input requesting to delete a portion of the first temporary image 611 other than a predefined format in a certain area or an input requesting to recover a certain temporary image corresponding to a state before generation of the first temporary image 611. Operations related to the above example will be described with reference to FIG. 9.

Referring to the image 620 in FIG. 6, the image forming apparatus 10 may receive a first input for changing “Kim” to “Park” in the first temporary image 611 and a second input for changing a picture of Michael Kim to a picture of Michael Park. Here, the picture of Michael Park may have been stored in the image forming apparatus 10 as an image file in advance. The image forming apparatus 10 may obtain first modified data 642 in a predefined format according to the first input. The image forming apparatus 10 may also obtain second modified data 644 in a predefined format according to the second input.

For example, the image forming apparatus 10 may combine the first data 631 with the first modified data 642 based on a position corresponding to the first modified data 642 in the first data 631 and the place of the first modified data 642 in a modification order. The image forming apparatus 10 may also combine the first data 631 with the second modified data 644 based on a position corresponding to the second modified data 644 in the first data 631 and the place of the second modified data 644 in the modification order.

For example, when modifications are performed at the same positions in a certain temporary image, the image forming apparatus 10 may locate modified data corresponding to the latest modification before modified data corresponding to a modification performed prior to the latest one. Specifically, the image forming apparatus 10 may locate the first modified data 642 corresponding to “Park” before data 643 corresponding to “Kim”. The image forming apparatus 10 may also locate the data 644 corresponding to the picture of Michael Park before data 645 corresponding to the picture of Michael Kim. As shown in the image 620 in FIG. 6, the image forming apparatus 10 may obtain second data 641 by combining the first data 631 with the first modified data 642 and the second modified data 644.

The image forming apparatus 10 may convert the second data 641 into a second temporary image 621. In the second temporary image 621, text indicating “Kim” in the first temporary image 611 is changed to text 622 indicating “Park” and the picture of Michael Kim in the first temporary image 611 is changed to a picture 623 of Michael Park.

The first input may be for modifying the size or color of a picture in a certain area of the first temporary image or for entirely or partially changing the picture.

In another example, the first input may request to delete a portion of the first temporary image other than a predefined format in a certain area.

In another example, the first input may request to recover the first temporary image or a certain temporary image corresponding to a state before generation of the first temporary image. For example, the first input may request to recover an original image.

The processor 1140 may obtain the second temporary image, which results from modification of the first temporary image, based on first modified data in a predefined format, wherein the first modified data is obtained from the first input.

For example, the processor 1140 may obtain the first modified data in the predefined format from the first input. When the first input is for modifying a letter in a certain area, the image forming apparatus 10 may obtain a modified letter as the first modified data in the predefined format. In detail, the processor 1140 may obtain digital code, by which the modified letter is expressed in machine language readable by a processor, as the first modified data.

For example, the processor 1140 may obtain second data by combining the first data with the first modified data. The second data may reflect a modification corresponding to the first input. For example, the processor 1140 may combine the first data with the first modified data based on a position corresponding to the first modified data in the first data and the place of the first modified data in a modification order.

The processor 1140 may convert the second data into the second temporary image, which results from modification of the entire or partial area of the first temporary image.

The history of modification of the first temporary image may include at least one of a history of modification from the first temporary image to the second temporary image and a history of modification from the original image of the first temporary image to the first temporary image.

In the same manner as the first data is displayed on the first printout, the second data may be transparently displayed on the second printout. The second data may be displayed in a certain size in a certain area of the second printout. The second data may be displayed in a margin of the second printout.

The processor 1140 may obtain a first image, which results from scanning the first printout. For example, a scanner of the image forming apparatus 10 may scan the first printout and obtain the first image as the scan result.

The processor 1140 may obtain a first temporary image, which results from extracting first data in a predefined format from the first image. For example, the processor 1140 may extract the first data in a predefined format from the first image. The processor 1140 may read the first data and convert the first data into the first temporary image including first information.

The processor 1140 may obtain a second temporary image, which results from modification of the first temporary image, based on a first input for modifying an entire or a partial area of the first temporary image.

The processor 1140 may output, as the second printout, a second image, which is generated by combining the second temporary image with second data corresponding to a modification history of the first temporary image

The method of operating the image forming apparatus 10 may be embodied as computer-readable storage media that store data or commands executable by a computer or a processor.
