Abstract

PURPOSE:To change the color of a document image into an optional color before the image is copied to a copying destination by changing the color of a relevant partial document image based on an input color changing instruction. CONSTITUTION:An image included in a prescribed range of the image read by a scanner 7 or the image produced by a pointing device 13 is registered into a hard disk 4 as a clip image. When this clip image is copied, the position of a copying destination is designated by the device 13 together with designation of a color change. Then a single end of the clip image is read into a work area 2b and a designated color changing process is carried out. The processed image is sent to a VRAM 17. When an image 20 is copied, the no-color processing is applied by designation for generation of an image 21. At the same time, a plane is checked for each color component in response to the designation of the image 20 and the dot of a picture element is converted. Thus an image 22 is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document image processing apparatus, and more particularly to a document image processing apparatus for creating and editing color document images.

[Prior Art] Conventionally, as a means for copying a document image, a process has been performed in which a partial image to be copied is registered and then copied to a desired position.

[Problems to be Solved by the Invention] However, in conventional copying processing, registration and copying involve only transferring image data between memories. When using different colors, it is necessary to erase the colors or change the colors after copying, which poses a problem of poor operability.

The present invention has been made in view of this problem, and it is an object of the present invention to provide a document image processing device that can change the color to an arbitrary color before copying an image to a copy destination.

[Means for Solving the Problem] A document image processing device of the present invention that solves this problem has the configuration shown below. In other words, creating a color document image
In a document image processing apparatus to be edited, a storage means for registering and storing a partial document image as a copy source, a designation means for designating a copy destination of the partial document image stored in the storage means, and a copy destination is specified by the designation means. The apparatus includes an input means for inputting an instruction related to desired color conversion when specified, and a copying means for converting the color of the partial image according to the instruction input by the input means and copying it to a copy destination.

[Operation] In the configuration of the present invention, when the copy destination of the partial document image stored in the storage means is specified, the color of the partial document image is converted based on the color conversion instruction inputted by the input means. Then, the color-converted partial document image is copied to the designated copy destination.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1. Explanation of the outline of the configuration (FIG. 1)> FIG. 1 shows the outline of the configuration of the electronic filing system in this embodiment.

In the figure, 1 is a CPU that controls the entire system. 2
1 is a memory, which is composed of a program area 2a storing programs related to control processing of the CPU 1 and a work area 2b for various processing. In addition to programs related to various processes (for example, editing processing, etc.), the program area 2a also stores programs related to the flowchart of FIG. 3, which will be described later. 3 is a floppy disk, and 4 is a hard disk. The floppy disk 3 is mainly used for backing up personal or common data, and the hard disk device is used when processing common data.

Reference numeral 5 denotes an FD/HD controller that controls the floppy disk 3 and the hard disk 4 to exchange data. Further, 6 is a printer that forms an image, and 7 is a scanner that reads an original image. Reference numeral 8 denotes an S/P interface, through which print data is output to the printer 6 and images are input from the scanner 7.

Reference numeral 9 denotes an SCS I interface which is a general-purpose interface, and a writable magneto-optical disk device 11 (including its controller 10) is connected to this interface. Note that this magneto-optical disk device 11
, also stores image information to be edited in the embodiment. Reference numeral 12 denotes a keyboard for inputting various characters and instruction information, to which a pointing device (mouse) 13 is connected. The input key information and the movement information from the pointing device 13 are output together as serial data. 14 is a serial interface that inputs this serial data and converts it into corresponding parallel data. 15 is a bit move unit (BMU) that transfers image data or performs bit control such as rotation, 16 is a character font storage unit that stores patterns corresponding to character symbol codes, and 17 is a unit that develops the displayed image as image data. 18 is a CRT that visualizes and displays the image data developed in the VRAM 17, and 19 is a companding unit that compresses the image or expands the compressed data.

Note that these various components are electrically connected via a bus 100 (including an address bus, a data path, and a control bus).

Explanation of attaching non-colored clips and attaching color-changed clips (Figure 2) The image is registered in the hard disk 4 as a clip image, for example. In addition, the registration process is
This is performed by specifying both end points of a diagonal line of a rectangular area containing the registration target image using the pointing device 13. Then, the image within the rectangular area that can be specified by the two specified points is transferred to the hard disk 4 and registered.

When a registered clip image is to be copied, the copy destination position is first specified using a pointing device or the like. Once the position is designated, it is designated whether or not to change the color of the registered clip image. At this time, there are two ways to designate a color change: a case where each specific color is changed to an arbitrary color, and a case where the entire clip image is changed to colorless.

In any case, if the color is not to be changed, the registered clip image is read from the hard disk 4 and transferred as is to the copy (transfer) destination memory. Further, when a color change is specified, the clip image is first read into the work area 2b, etc., and the specified color conversion process is performed.

Then, processing is performed to transfer the color-converted results to the VRAM 17.

The explanation using FIG. 2 is as follows.

In addition, the color image in the example has R, G, B per pixel.
By superimposing the branes for each color component, the seven colors black, blue, red, purple, green, light blue, yellow, and white are expressed by one bit.
A case in which colors are displayed will be explained.

When copying a registered clip image 20, if no color is specified, an image 21 is generated by performing colorless processing. As the no-color processing, for example, in a plane for each color component, if there is at least a pixel of "1" at the same pixel position, the color is black, and if all the pixels are "O", the color is white.

Also, when the clip image 20 is specified as ゛゜red-one-blue゛゛ or "yellow → colorless (black)", the branes for each color component are checked and the dots with only red branes are changed to ゛゛l゛. For the pixel, only the blue brane is set to “1”
, ゜゜.

Also, yellow is when the dots in the red and green branes are both ゛゜1゛゛, and the blue brane is ``゜0''゛, so when such pixels are detected, they are all ``1''.
(or "O") to generate colorless color. As a result, image 22 is obtained.

<Explanation of Processing Procedure (FIG. 3)> Processing related to clip pasting (copying) in this embodiment will be explained according to the flowchart of FIG. 3. Note that the description will be made assuming that the Curip image has already been registered on the hard disk 4.

First, when a clip pasting designation (a clip image copying position designation) is made in step S1, the process proceeds to step S2, and it is selected whether or not to paste with a different color.

If nothing is selected, the process of step S3 is executed to paste the registered clip image in its original color.

Also, if you select the colorless mode of color conversion,
Proceeding to step S4, the registered clip image is converted to colorless, and processing for pasting it at the designated position is performed in step S5.

If the mode in which each color is changed independently is selected, the process proceeds to step S6, where the user specifies which color is to be changed to which color.

This process is repeated until it is determined in step S7 that no next color change is made or that all colors have been specified. Thereafter, the process proceeds to step S8, in which pixels of the color to be changed in the registered clip image are searched out one by one and converted to the specified color.

When the conversion process to the color specified by the operator is thus completed, the process proceeds to step S9 and the converted image is pasted at the specified position.

<Description of other embodiments> In the embodiment, when pasting a color change clip, the color to be specified for color change is input and specified. Next, the color may be changed to a color indicated by interlocking with the pointing device 13.

Note that the present invention can be freely modified within the scope of the claims, and is not limited to the embodiments described above. For example, in the embodiment, copying of an image has been described as an example, but documents can also be processed using the same principle.

[Effects of the Invention] As described above, according to the present invention, it is possible to improve the operability of copy processing related to color images.
