Abstract

PURPOSE:To attain the movement expected by the user by providing a picture processing means executing rotation processing and moving processing based on a coordinate of an input picture and a means forming a picture onto a recording sheet to the device. CONSTITUTION:A picture processing section is connected to a picture memory and a controller executes directly write/read of a picture. Picture data are written in the picture memory while making coordinate conversion as shown in the following to rotate an output picture after the end of reading of a usual picture (Xo, Yo) (Zn, Wo), (Xo, Yn) (Zo, Wo), (Xn, Yo) (Zn, Wn), and (Xn, Yn) (Zo, Wn). A file margin is formed to a rotated picture by using a picture memory and the picture is moved on the coordinate with respect to recording paper, then a picture 504 is outputted. That is, no file margin is formed to the left end of the original. In order not to form the picture as above, a space for the file margin along with the intention of the user is formed by forming a space on the coordinate with respect to the original when the rotation processing is executed.

In order to solve the above problems, the present invention provides input means for inputting an image, image processing means for performing rotation processing and movement processing of the image input from said input means, and said image. And an image forming unit for forming an image from a processing unit on a recording sheet, the image processing unit performing processing based on coordinates in an input image. Is.

The processed image is transmitted to the printer unit 212 having the exposure control unit 10 and forms an image on the photoconductor 11. Further, the image processing section 211 is connected to an image memory 220 capable of storing an image of a document, and the control device 200 can directly control the writing / reading of an image to / from the image memory 220.

It is performed according to the program in the ROM 240.

By using the image memory, it is possible to rotate the original image and output the image. An example of this image rotation method is shown in FIG.

FIG. 4 shows an original image, a stored image, and an output image. Normal image reading is (X0, Y0)
To (X0, Yn), and thereafter, scanning is performed up to Xn for each line, thereby ending the reading of the image. In order to rotate like the output image in FIG. 4, the image is written in the image memory 220 as follows.

(X0, Y0) → (Zn, W0) :: (X0, Yn) → (Z0, W0) ::: :( Xn, Y0) → (Zn, Wn): :( Xn, Yn) → (Z0, Wn)

By thus writing the image data in the image memory 220 while performing the coordinate conversion, image data such as the stored image in FIG. 4 can be stored in the image memory 220. Then, while reading the image data from the image memory in the following order, the output image of FIG. 4 can be obtained by scanning in the main scanning direction by the laser scanning of the exposure control unit 10, and as a result, the original image is rotated. The resulting output image is complete.

With reference to FIG. 5, a comparison will be made when the binding margin is set in the copying machine.

Reference numerals 501 and 502 are conceptual views in the mode in which the image is not rotated and in the binding margin mode. Manuscript 50
The output image 502 when the binding margin is set for 1 is
An image of a document is formed by shifting the edge of the recording paper on which the image is formed with coordinates based on the recording paper as the binding margin, and a margin is formed on the paper.

Reference numerals 503 and 504 are recording paper standard systems.
This is a case where a binding margin is created in a rotated image using the image memory 220. An image such as 504 is output when the recording sheet is moved with coordinates as a reference.

However, the user cannot try to create a binding margin at the left end of the document.

In order to obtain an image like 504, when the rotation process is performed, the margin is formed at the coordinates with respect to the original so that the margin for the binding margin can be formed according to the user's intention. (505, 506).

In the case where originals of different sizes are mixed and fed by the original feeding device 1 and the image is moved simultaneously by using the rotation function to create a margin for the binding margin, the originals are set on the basis of the originals. If the binding margins are created at the basic coordinates of movement, the direction of the margins is not constant, so the margins are created at the coordinates based on the recording paper. This makes it possible to smoothly perform bookbinding work and the like when the originals are mixed, and further reduce the burden on the user.

FIG. 6 shows a flowchart of the first embodiment. According to this flowchart, the control is started when the binding margin mode is selected in step 310. When it is determined Yes in step 310, the amount of movement (mm) for binding margin is input in step 315. After that, the reference coordinates for image movement are selected. If the mixed loading mode is selected (step 320) or the rotation process is not performed (step 330), the reference coordinates for image movement are based on the recording paper. Is used (step 350).
The coordinate conversion from 501 to 502 in FIG. 5 corresponds to this.
On the other hand, when it is determined Yes in step 330 and the rotation process is performed, the coordinates (step 340) with the original as the reference are used as the reference coordinates for image movement. 50 of FIG.
The coordinate conversion from 5 to 506 corresponds to this. Further, according to the reference coordinates determined in the determination item of the reference coordinates (steps 340 and 350), the image movement amount (M) for the margin determined in 315 in the image movement process of step 355 (M
x) Move the image. Here, since the movement by Mx is performed with reference to the x-axis in FIG. 5, if the image is not moved by converting the coordinate to the coordinate axis based on the document like 506, an inappropriate image like 504 is displayed. Is formed.

In this way, even when the image is rotated using the image memory and the binding margin is formed by moving the image, it is possible to generate an appropriate binding margin by changing the coordinate serving as the reference of movement. Becomes

Next, an example applied to the function of moving one part of the document to an arbitrary position will be described as a second embodiment.

In the second embodiment, like the first embodiment, it is possible to obtain an appropriate image by converting the coordinate axes.

FIG. 7 shows a conceptual diagram of the second embodiment. In the present embodiment, coordinate conversion in the case of designating an area of one part of the document (trimming) and moving (moving) the trimmed image to another arbitrary place will be described. 701 and 702 are conventional trimming, 703 and 70
4 is a diagram of trimming + movement. When an original image such as 705 is moved at the coordinates of the paper reference, an image like 706 is obtained. This is different from the image originally intended by the user, as can be seen by comparing it with the dotted arrow 705. come. Therefore, by changing the reference for moving the image to the coordinate based on the original as in 708, the image intended by the user can be surely obtained even during the rotation processing.

FIG. 8 shows a flowchart of the second embodiment. The control according to this flowchart is performed when the movement mode (step 510) is selected. When it is determined Yes in step 510, the start point and the end point of movement are determined as shown in FIG. After that, reference coordinates for image movement are selected in the same manner as in the first embodiment, and step 55 is selected.
After performing the rotation process in 5, it is possible to obtain an appropriate image such as 708 by moving the image based on the coordinates with respect to the document.

Processing such as rotation and movement may be performed when the image is stored in the image memory 220 or may be performed when being read out from the image memory 220.

Further, the invention is not limited to the transfer machine and may be applied to a printer or the like.

[0039]

As described above, according to the present invention,
Since the rotation and movement processing is performed based on the coordinates in the input image, the movement expected by the user can be performed.
