Abstract

PURPOSE:To specify the editing of an arbitrary shape without soling an original, and to edit the image of the original. CONSTITUTION:A mark sheet 12 is superimposed on the original 14, and a desired editing region M is marked by handwriting. Then, a CCD 20 reads the bar code 13 of the set mark sheet 12 and the editing region M. A mark sheet discriminating part discriminates the bar core 13, and memory exclusive for the mark sheet stores the editing region M of the mark sheet 12 as image data. When the original 14 is set, the CCD reads the fact, and the mark sheet discriminating part decides that the read image is the image of the original 14. The image data of the original 14 is edited based on the editing region M stored in the memory exclusive for the mark sheet.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing a mark sheet used in an image editing apparatus according to the present invention, and FIG. 2 is an explanatory diagram showing the mark sheet of FIG.
FIG. 2 is a block diagram of main parts showing an embodiment of an image editing device using a computer.

In FIG. 1, a mark sheet 1 for specifying an editing area used in the image editing apparatus of this embodiment is shown.
The mark sheet 2 is composed of a transparent or semi-transparent sheet, and a bar code 13 as an example of an identification mark for distinguishing the mark sheet 12 from the original image is preliminarily provided at the corner of the sheet. printed. Note that the bar code 13 indicating that it is for specifying an editing area may be any other identification mark.

When editing an image of a desired area of the original 14, the operator first places the mark sheet 12 on the original 14.
are overlapped, and while viewing the document 14 through the mark sheet 12, a desired editing area M is marked by hand using a red pen, a black pen, or the like. Next, the marked mark sheet 12
is removed from above the original 14 and set at a predetermined original reading position provided in the image editing device.

In FIG. 2, the image editing apparatus includes a CCD (charge-coupled device) 20 as an example of imaging means, an A/D converter 21, a mark sheet discriminator 22 as an example of discriminator, and a mark sheet discriminator 22 as an example of discriminator. It is provided with a memory 23 exclusively for the seat, and these components are configured to function as follows.

First, the CCD 20 reads the bar code 13 and the editing area M of the set mark sheet 12, and outputs it to the A/D converter 21 as an analog image signal. The A/D converter 21 converts this into, for example, 256 gradations (
8-bit) digital signal. The mark sheet discrimination unit 22 detects the bar code 13 of the mark sheet 12 in advance.
The bar code 13 read by the CCD 20 is determined. When it is determined that the mark sheet 12 has been read due to the presence of the barcode 13, the mark sheet dedicated memory 23 stores the editing area M of the mark sheet 12. Store as image data.

Next, when the operator removes the mark sheet 12 from the reading position and sets the original 14 in its place, the CCD 20 reads the set original 14 and converts it into an analog image signal. The A/D converter 21 converts this into a digital image signal. In this case, the mark sheet discriminator 22
makes a determination that the bar code 13 does not exist in the image information read by the CCD 20, that is, determines that the read image is the image of the original document 14.

Here, the image editing device includes a memory 24, a scaling processing section 25, and a density processing section 26, which constitute an example of editing means, and these components are respectively configured to function as follows. It is configured.

That is, when the mark sheet discriminator 22 determines that the image is the image of the original 14 as described above, the image signal storage memory 24 stores the digital signal from the A/D converter 21. Stores image signals. At this time, for example, CCD2
MTF correction, black and white correction, and gamma correction are applied according to the characteristics of the reading unit such as 0, etc., and the histogram block
6. After adding each pixel density of each gradation to generate density information, converting the 8-bit signal into a binary 1-bit signal using an error diffusion block and performing pseudo-halftone processing, the signal is stored in the memory 24. It may be configured as follows.

The image of the original 14 stored in the memory 24 is subjected to trimming or other image processing within or outside the editing area M stored in the mark sheet dedicated memory 23. will be applied.

At this time, MTF correction, black and white correction, and gamma correction are applied to the signal of the image of the document 14 only within the editing area M or only outside the editing area M, depending on the characteristics of the output section of the printer, etc. It may be configured such that density information is generated using a histogram block and pseudo halftone processing is performed using an error diffusion block.

If scaling processing is specified here, the scaling processing section 25 converts the binarized data in the memory 24 into multilevel data, for example, into 8 bits with 256 gradations, and then converts it to the scaling factor. Interpolation is performed accordingly, and the density value of the pixel after scaling is calculated. In this scaling process, it is preferable to scale the image in the sub-scanning direction and then scale the image in the main scanning direction.

Next, the density processing section 26 performs density conversion on the digital signal of, for example, 256 gradations using the gradation conversion table, and outputs the converted image signal.

Particularly in this embodiment, the image signal from the density processing section 26 is output to a laser 27 of a laser printer serving as an output device. Laser 2 driven by this signal
The laser beam from 7 is optically scanned in the main scanning direction through an appropriate optical system by an optical deflector such as a polygon mirror or a hologram disk, and is electrostatically deposited onto the photosensitive drum rotating in the sub-scanning direction. form an image. Next, this electrostatic latent image is visualized on a predetermined sheet of paper and output as an image on which the above-described editing operation has been completed.

It should be noted that the CCD 20 is connected to the bar of the mark sheet 12.
If the code 13 is read continuously, the editing process is stopped and the editing area M stored in the mark sheet dedicated memory 23 is erased.

In the above embodiment, the image on the mark sheet 12 is first read and then the document 14 is read. However, after the document 14 is first read and stored in the memory 24, , the image of the mark sheet 12 may be read and edited as an editing area.

As described above, according to this embodiment, the operator can:
When editing an image in a desired area of the original document 14, the mark sheet 12 is placed on the original document 14 in advance and the editing area M is marked by hand, and then the mark sheet 12 is first edited. Since the images of the editing area M and the original 14 are read, the image of the original can be edited by specifying an editing area of any shape with an inexpensive configuration without staining the original.
