While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

It is to be understood that the invention is not to be limited to the specific forms thereof which are to be described in the foregoing description, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims. .

The operation and effect of the print output control system and the operation method of the present invention having the above configuration will be described as follows.

First, the present invention allows a user to arbitrarily change the attribute of a printed matter output from a computer, thereby obtaining a corrected output result as a result of a user's desire.

To this end, the present invention is implemented by executing a program for installing a hooking module 12 provided in the print control module 10 in a computer.

At this time, FIG. 5 can set brightness, contrast, saturation, gamma, and the like in the setting screen window of the print output control system applied to the present invention.

In the present invention, the hooking module 12 monitors all print processes occurring in a computer application program and detects a color image correction value gamma, contrast, brightness, The print output control system is operated through the step of obtaining the color correction output set by the user differently from the color output of the original output.

This will be described in more detail as follows.

In the step of obtaining the corrected output, a hooking module 12 for controlling a printing state occurring in an operating system (OS), which is a computer operating system, adjusts the color correction value gamma, contrast, Brightness, and saturation values, and passes them to a graphics device interface (GDI) 15 of an operating system (OS) to correct the color of the output image.

In the step of obtaining the corrected output, an image (Image), a text (Text) which are objects to be output in accordance with an option set by the user by operating a hooking module 12 during printing in an application program, , And a diagram (Diagram).

Also, the step of obtaining the corrected output converts the values of R (Red), G (Green), and B (Blue) of the input original data into grayscale values, ) So that the output state can be forcibly obtained as a grayscale output.

In addition, the step of obtaining the corrected output may include extracting characters, images, and graphics from the contents of a document outputted from a hooking module 12 for controlling a printing state generated in an operating system (OS) The printed matter is outputted.

In addition, in the step of obtaining the corrected output, the hooking module 12 adjusts the brightness, which is a color correction value, to finally adjust the printing density of the printed output so as to save ink and toner of the printer.

Particularly, in the step of obtaining the corrected output, a watermark, an image overlay, and an attribute are added to the output control program to enhance security.

In addition, the USB authentication key module 13 detects a security problem, which is arbitrarily outputted in addition to the authorized user according to the setting of the user, in the hooking module 12 to control the setting and release of the hooking system, Can be solved.

In addition, the password is stored in the USB authentication key module 13 so that only the authenticator can be output upon output.

The more specific effects of the present invention will be described as follows.

The application 11 of the present invention is programmed through an API (Application Program Interface) provided in Windows. Using this point, the hooking module 12 performs necessary operations between the application program 11 and the GDI (Graphic Device Interface) 15, and transmits the intended result back to the GDI (Graphic Device Interface) 15) to implement the output color correction purpose.

In particular, the printing control module 10 of the present invention includes a hooking module 12 and a USB authentication key module 13.

The hooking module 12 operates in a manner intercepting an API (application program interface) between an application program 11 and a graphic device interface 15 of a Windows. This hooking module 12 is connected to a GDI (Graphic Device Interface) 15 (Application Programming Interface) when using an application program interface (API) related to a printing operation in an application 11 of a Windows ) Module, the data is transferred to the GDI (Graphic Device Interface) 15 to process all the processes before being processed by the device driver. Thus, regardless of the type of the printing device and the model of the manufacturer, It can operate as software and device independent.

In the Windows, the hooking module 12 recognizes whether or not the current state is outputable via the USB authentication key module 13 before and after the operation. If there is no USB authentication key before the printing operation or if the user does not pass the USB authentication key, the GDI (Graphic Device Interface) 15 is controlled so that the printing is terminated.

2 of the present invention shows a process of controlling the hooking module 12 to prevent the printing operation from being performed by the hooking module 12 when the USB authentication key is disconnected from the user's computer It is a flowchart.

In the above process of the present invention, a color system is referred to as a color system (color system), which is a color system of color (color) or color (color). Color (color light) is a color mixing system that displays all colors with three stimulus values by additive color mixing of light color. On the other hand, the color is referred to as a color appearance system by arranging and coloring the standard color chart as an object color in a systematic manner such as hue, brightness and saturation. In the present invention, when the content of an original document is outputted through a printer apparatus, the gamma, brightness, contrast, and saturation of the original document are controlled, We want to get the output of color area.

The gamma (Gamma) refers to nonlinearly transforming the intensity signal of light using a nonlinear transfer function. In general, Gamma Correction is used to resolve color system inconsistencies between devices. This Gamma value can be transformed from the Hooking module 12 into a color system desired by the user to obtain an optimized color output.

Brightness refers to the degree of light and darkness when the light is projected. The print density can be adjusted by adjusting the brightness of the output data.

Contrast is also used to indicate differences between light and dark areas. You can increase the sharpness of the image by brightening the areas that are too bright or too dark.

In addition, saturation refers to the property that shows clearness, shade, pureness, intensity of color, saturation of color. The user can obtain saturation output by adjusting the saturation.

FIG. 3 shows a graphical device interface (GDI) in the application program 11 according to the color correction values (gamma, brightness, contrast, saturation) The color data included in the data (e.g., characters, images, figures, etc.) input to the input device 15 is processed according to the set correction value to transmit the modified color data to the GDI (Graphic Device Interface) In a flowchart of FIG.

Such a color system correction has an effect of obtaining output data changed to a color system of various users.

There are various algorithms for the color image correction method. The Gamma, Brightness, Contrast, and Saturation correction algorithms used in the present invention can use various algorithms that are generalized according to the state of the output image quality.

Also, FIG. 3 shows an example in which when a color printer (irrespective of the type of device) is output from a Windows application 11, an application 11 to a GDI (Graphic Device Interface) 15 Green, and Blue values of the input data are converted into grayscale, and then the same values are added to Red, Green, and Blue to be transferred to the GDI (Graphic Device Interface) 15, It is a flowchart of the method of obtaining the output of grayscale.

The following Equation (1) is obtained by processing a pixel value of a pixel of Red, Green, and Blue values of an original image data, processing it as a gray value, and then assigning the values to Red, Green, and Blue, In the case of the first embodiment.

(1)

Gray = (0.299 * Red) + (0.587 * Green) + (0.114 * Blue)

Red = Green = Blue = Gray

The text and diagram of the present invention are obtained by obtaining the color value of the corresponding object and passing the value to the GDI in the same manner as in Equation 1 and then transmitting the color text, Color Diagram) to a gray scale character (Text) or a graphic (Diagram).

FIG. 4 is a diagram showing an example in which an application program 11 is connected to a GDI (Graphic Device Interface) 15 when a color printer (regardless of the type of the device) is output from a Windows application 11 Objects to be input You can limit the output data by filtering APIs corresponding to text, image, and diagram.

Such filtering may be configured to extract a specific character from the original document, replace it with another designated character or delete it, and print the filtered content back to the final output document.

In addition, you can filter out only the text that is output to the original document, save it, and use the file for other purposes.

In addition, only the image that is output to the original document is filtered separately, and then the individual image (Image) is stored. Saved image files can be used for other purposes.

In addition, only the diagrams that are output to the original document are separately filtered, and then the individual diagrams are stored. The stored diagram files can be used for other purposes.

FIG. 9 is a screen window showing an output of the graphic brightness setting according to the present invention, FIG. 10 is a screen window showing an output set in gray scale according to the present invention, and FIG. FIG. 11 is a screen window showing the output of a change in brightness in the gray scale according to the present invention. The color correction value (gamma, brightness, contrast) set by a user regardless of an application program, (Contrast, Saturation), it is possible to obtain various final printouts different from the original.

12 is a screen for setting filtering according to the present invention, FIG. 13 is a screen window showing an image filtering applied output according to the present invention, FIG. 14 is a screen for showing a text filtering applied output according to the present invention, Window, and FIG. 15 is a screen window showing a figure-filtering applied output according to the present invention, so as not to output images, text, and graphics in a print document.

In addition, the present invention is effective in that a USB authentication key is installed in a user's computer and a hooking module capable of controlling printing is installed so that only an authorized user can output, thereby preventing an arbitrary user from outputting the output.

In addition, the present invention modifies Red, Green, and Blue values input from a GDI (Graphic Device Interface) in an original document into grayscale when outputting from hooking for controlling printing, So as to print in grayscale when printing a document composed of color in a color printer, thereby reducing the cost of consumables related to color printing.

Finally, according to the filtering option set by the user, an object (e.g., a character, an image, a graphic form, etc.) included in an original document is filtered to prevent the user from viewing the final output, thereby saving security and consumables. will be.

The technical idea of the print output control system and the method of operation of the present invention is that the same results can be repeatedly practiced.
