Description

  The present invention relates to an image processing apparatus, an image processing program, and an image forming apparatus.

  In recent years, from the viewpoint of strengthening security, such as prevention of printing outflow and tracking, technologies that superimpose duplication prohibition marks on the original image or add a superimposed image containing various attribute information have attracted attention. .

  This superimposed image is generally printed on the entire surface in order to prevent a part from being cut off or missing. The conventional superimposition image has been mainly used for deterrent effects such as characters appearing when printed, but now it is possible to add a copy prohibition mark and attribute information of the printed matter, not by user selection but forcibly. The operation of attaching a superimposed image has increased.

  It is common for the machine administrator who manages the MFP to set whether to superimpose the superimposed image. The machine administrator enters the administrator mode each time and turns off the forced superimposition setting. Generally, after executing the printing process, the machine manager mode is entered again to turn on the forced superposition.

  In Patent Document 1, when there is no specific paper in the tray selected at the time of selecting the specific paper feed mode, the predetermined original is switched to the same mode in which the normal paper is fed from another tray with respect to the predetermined original. An apparatus is disclosed that includes release means for resetting a predetermined document same mode after a copy operation in the same document mode is completed.

  Patent Document 2 discloses an apparatus that automatically clears a set copy mode and returns to the standard mode automatically immediately after the end of the copy operation.

Patent Document 3 discloses a technique for requesting cancellation of authentication when an image processing service authenticated by an authentication device connected to an external network is terminated.

This optical scanning device includes, for example, a laser light source that outputs laser light in accordance with image information, a polygon mirror (rotating polygonal mirror) that deflects laser light from the laser light source in a predetermined direction, and laser light deflected by the polygon mirror. It includes a scanning optical system that forms an image on the photoreceptor so that it can be scanned at high speed.

  In the image forming apparatus 10 according to the present embodiment, the forced printing mode is one of modes that can be set and canceled by an administrator who has a wider authority than a general user as an authority for performing various setting operations of the image forming apparatus 10. have. When the forced printing mode is set, for example, when the image forming apparatus 10 performs a copying operation, a predetermined predetermined superimposed image such as “copying prohibited” is superimposed on the original image and output (printed). The

  Such a forced printing mode can be set and canceled only when, for example, administrator information such as an administrator ID and a password is input and authenticated on an authentication screen for the administrator.

  As described above, in this embodiment, only the administrator can set and cancel the forced print mode. However, as described later, the forced print mode is temporarily canceled and the forced print mode is set after the temporary release. It is also possible for users.

  Next, as an operation of the present embodiment, a control program executed by the CPU 12A will be described with reference to a flowchart shown in FIG. 2 is stored in advance in the nonvolatile memory 12D as an example, and the CPU 12A reads the control program from the nonvolatile memory 12D and executes it. Alternatively, the control program may be stored in the hard disk 24 instead of the nonvolatile memory 12D, and the control program may be read from the hard disk 24 and executed. Furthermore, the control program may be supplied from another computer or the like via the network 30 and the network communication unit 14, for example, or may be supplied from a recording medium such as a CD-ROM.

  The control program shown in FIG. 2 is executed when the image forming apparatus 10 is turned on and the forced printing mode is set by the administrator.

  Further, for example, the non-volatile memory 12D stores forced print mode setting information indicating that the forced print mode is set or canceled, and the forced print mode is referred to by referring to the forced print mode setting information. It is possible to know whether is set or released.

  First, in step 100, it is determined whether or not the forced print temporary release button is pressed on the forced print setting screen. When a general user performs a predetermined operation for reading a setting screen on a menu screen (not shown) displayed on the operation display unit 20, a setting screen 40 as shown in FIG. 3A is displayed on the operation display unit 20. . In the setting screen 40, when the “security” tab 42 is pressed from a plurality of tabs and the “forced print setting” button 46 is pressed from the submenu 44, a “forced print temporary release” button 48 is displayed. Even when the forced print mode is set by the administrator, when the general user presses the “forced print temporary release” button 48, the forced print mode is temporarily released.

  If the “forced printing temporary release” button 48 is pressed, the process proceeds to step 102, and if the “forced printing temporary release” button 48 is not pressed, the process proceeds to step 116.

  In step 102, a password input screen 50 for temporarily canceling forced printing as shown in FIG. The password input screen 50 includes a password input field 52, a “keyboard” button 54, a “decision / next selection” button 56, a “cancel” button 58, and a “confirm” button 60. When the “keyboard” button 54 is pressed, a keyboard screen (not shown) is displayed, characters such as alphabets and numbers can be selected, and the selected characters are input to the password input field 52. When the password for forced printing temporary release is input in this way and the “decision / next selection” button 56 is pressed, the password input in the password input field 52 is completed. When the “cancel button” 58 or the “confirm” button 60 is pressed, the routine proceeds to step 104.

  In step 104, it is determined whether or not the “cancel” button 58 is pressed. If the “cancel” button 58 is pressed, the process proceeds to step 116, and if the “cancel” button 58 is not pressed, that is, “ When the “confirm” button 60 is pressed, the routine proceeds to step 106.

  In step 106, it is determined whether or not the password input in the password input field 52 matches the password for forced printing temporary release stored in advance in the nonvolatile memory 12D. If there is no match, control proceeds to step 116.

  In step 108, a temporary cancel designation screen 62 for designating forced print temporary cancellation as shown in FIG. The temporary release designation screen 62 includes a release designation check box 64 and a “close” button 66. When the check box 64 is pressed on the temporary release designation screen 62, the check box 64 is checked as shown in FIG. When the “close” button 66 is pressed, the process proceeds to step 110.

  In step 110, it is determined whether or not the check box 64 is checked. If checked, the process proceeds to step 112. If not checked, the process proceeds to step 116.

  In step 112, the mode is shifted to the forced printing temporary release mode, and information indicating that the forced printing mode is released is written in the nonvolatile memory 12D as the forced printing mode setting information. Further, a setting screen 68 for resetting to the forced printing mode as shown in FIG. This setting screen 68 includes a “forced printing addition” button 70 for resetting the temporarily canceled forced printing mode.

  In step 114, for example, information (temporary release information) such as the time when the forced print mode is temporarily released is stored in the hard disk 24 as log data.

  In step 116, it is determined whether or not the “forced print addition” button 70 has been pressed. If pressed, the process proceeds to step 118, and if not, the process proceeds to step 120.

  In step 118, the mode is again shifted to the forced printing mode, and information indicating that the forced printing mode is set is written in the nonvolatile memory 12D as the forced printing mode setting information. Further, a setting screen 40 for temporarily canceling the forced printing mode as shown in FIG. 3A is displayed on the operation display unit 20.

  In step 120, it is determined whether or not a start button (not shown) included in the operation display unit 20 has been pressed. If pressed, the process proceeds to step 122. If not pressed, the process returns to step 100 to return to the above. Repeat the same process. For example, when the user wants to copy, the user can start copying by setting a document and pressing a start button. In the present embodiment, a case where the copy process is selected and executed by the user as the print process will be described, but the print process is not limited to the copy process. For example, it includes a case where document data such as a facsimile document or a print document temporarily stored in a confidential box is read and printed, or a case where various data such as scan image data temporarily stored in a confidential box is read and printed. .

  In step 122, a printing process as shown in FIG. 4 is executed. As shown in FIG. 4, in step 200, the scanner unit 18 is instructed to read the set original, and the image recorded on the original is read.

  In step 202, it is determined by referring to the forced print mode setting information stored in the nonvolatile memory 12D whether or not the forced print mode has been temporarily canceled. If the forced printing mode is temporarily canceled, the process proceeds to step 204. If the forced printing mode is not temporarily canceled, the process proceeds to step 206.

  In step 204, an instruction is given to the mark giving unit 26B of the image processing unit 26 to synthesize the image read in step 200 and the mark indicating that the forced printing mode has been temporarily canceled. As a result, an output image in which a mark is added to the original image is generated. It is not always necessary to add a mark, and the process of step 204 may be omitted.

  On the other hand, when the step 206, that is, the forced printing mode is set, the superimposing unit 26A of the image processing unit 26 in order to superimpose a predetermined superimposition image, for example, a “duplication prohibited” character image, on the image read in the step 200. To instruct. Note that the characters “duplication prohibited” are superimposed so that a plurality of characters are printed on the background of the original image, for example. As a result, an output image in which the characters “duplication prohibited” are superimposed on the background of the original image is generated.

  In step 208, the generated output image is output to the image forming unit 28, the output image is printed, and this routine ends.

 In step 124 of FIG. 2, it is determined whether or not the forced printing temporary release mode is selected. If the forced printing temporary release mode is selected, the process proceeds to step 126. If not, the process proceeds to step 128. To do.

  In step 126, information indicating that the forced print mode is set is written in the nonvolatile memory 12D as the forced print mode setting information in order to reset the forced print mode.

  In step 128, it is determined whether or not a power button (not shown) included in the operation display unit 20 has been turned off. If the power button has not been turned off, the process returns to step 100 to repeat the same processing as described above. If it is turned off, this routine is terminated.

  In this embodiment, the case has been described in which the forced printing mode is automatically reset after the completion of the printing process, but in the forced printing temporary release mode, the forced printing is automatically performed immediately after the printing process is completed. Instead of resetting the mode, the timer 22 may measure the period when there is no operation, and may reset the mode to the forced printing mode when there is no operation for a predetermined period.
