Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus,
In particular, the present invention relates to an image forming apparatus suitable for easily setting a scaling ratio of a formed image with respect to an original image.

[0002]

2. Description of the Related Art Conventionally, in an image forming apparatus such as a copying machine, a scaling ratio of a formed image (copy image or the like) with respect to an original image is 101%, 102%, 10% by a scaling ratio setting key.
Those that can be arbitrarily set such as 3%, ..., 99%, 98%, 97%, are known.

However, in such a system, it is difficult to predict the size of the actual formed image (copy image or the like) obtained by the set scaling ratio, so that the X of the original image is The distance between the two points in the direction and the distance after the scaling between the two points are numerically input, and the distance between the two points in the Y direction and the distance after the scaling between the two points are similarly set. A method of inputting numerical values has been developed.

In this numerical input method, for example, as shown in FIG. 6, in the zoom program mode, first, the size of the document in the horizontal direction (X direction) and the vertical direction (Y direction) is input with the ten keys. (FIG. 6A) Next, the horizontal and vertical sizes of the copy image (formation image) are input using the ten keys (FIG. 6B). The input of the original size and the copy size completes the setting of the scaling factor (FIG. 6C). That is, when the document size and the copy size are input, the calculation of copy size / document size is automatically performed inside the apparatus to automatically calculate and set the scaling factor.

[0005]

However, in the conventional numerical value input method, for example, when scaling is performed so that a specific portion of a picture in a document image has a desired size, the operator specifies the picture. It is necessary to measure the lengths in the X and Y directions using a ruler or the like for the part and input the measured lengths in the X and Y directions as the “copy size” numerically, which makes the operation in advance complicated. .

The present invention has been made under such circumstances, and an object thereof is to provide an image forming apparatus capable of easily inputting information for automatic calculation of a scaling factor.

[0007]

In order to achieve the above object, an image forming apparatus according to the present invention calculates a position designating means and a distance between two points of a document image arbitrarily designated by the position designating means. When the distance between the distance calculation means and the distance between the scaled formed image corresponding to the two points is set, the set distance between the scaled formed image and the two points calculated by the distance calculation means And a scaling factor calculating means for calculating the scaling factor of the formed image with respect to the original image based on the distance between the two.

[0008]

Now, it is assumed that, for example, the digitizer as the position designation means designates any two points of the original image and the distance between the two points of the formed image after scaling is set. The setting of the distance of the scaled formed image corresponding to the two points may be directly input by a ten-key pad, or two points of the scaled formed image corresponding to any two points of the original image may be digitized. When specified by, etc., it is set by calculating.

In this case, the distance calculating means calculates the distance between two points of the original image designated by the digitizer. Then, the scaling factor calculating unit sets the scaling factor of the formed image with respect to the document image based on the set distance of the formed image after scaling and the distance between two points of the document image calculated by the distance calculating unit. calculate. In this way, the information for automatic calculation of the scaling factor can be easily input.

Embodiments of the present invention will be described below with reference to FIGS.

[First Embodiment] FIG. 1 is a block diagram showing the schematic arrangement of a copying machine to which an image forming apparatus according to the first embodiment of the present invention is applied. CPU 1, RAM 2, ROM 3,
It has a copy processing unit 4, an LCD 5, and an operation unit 6.

As shown in FIG. 2, the operation section 6 has a digitizer 61, a ten-key pad 62, a mode setting key 63, a start key 64, etc. The digitizer 61 is provided with a document abutment 61a. , The digitizer pen 61b is used to specify the coordinate position on the manuscript.
Is used to input the length after scaling corresponding to the length between the coordinate positions of two points on the original specified by the digitizer pen 61b. The LCD 5 shown in FIG. 2 is the same as the LCD 5 shown in FIG.

In accordance with a program stored in advance in the ROM 3, the CPU 1 causes the copy processing unit 4 to feed / discharge copy paper, read / record an original image, perform various copy processing such as scaling processing, and use the digitizer 61. It controls display processing such as displaying the designated coordinate position on the document on the LCD 5. In addition, the CPU 1 performs the scaling process.
The distance between the two points is calculated based on the coordinate positions of the two points on the original specified by the digitizer 61.
The scaling factor is calculated and set based on the calculated distance between the two points on the document and the length after scaling input by the ten-key pad 62. The CPU 1 uses the RAM 2 when performing the copy process and the scaling ratio calculation / setting process. That is, the RAM 2 has a work area for performing a scaling process and the like in addition to the image area for storing the read original image.

Next, the scaling ratio setting operation in the first embodiment will be described based on the flowchart of FIG. 3 and the operation example of FIG.

A document table (not shown) and the digitizer 6
If the zoom program mode is set by the mode setting key with the original placed on the CPU 1, the CPU 1
The operation guidance information "Enter the dots with the digitizer" is displayed on the LCD 5 (FIG. 4A, step S1 in FIG. 3). Therefore, the digitizer pen 61b designates / inputs an arbitrary point such as the edge of the picture to be scaled to a specific size on the original placed on the digitizer 61 as the first point P1 (FIG. 4B). , Step S2).

Then, the CPU 1 executes the designated / input 1
The point P1 and the operation guidance information "Enter the second point with the digitizer" are displayed on the LCD 5 (Fig. 4
(B), step S3). Therefore, if other points such as the edges of the picture are designated as the second point P2 and arbitrarily designated and input by the digitizer pen 61b (FIG. 4 (c), step S).
4), the CPU 1 LCs the designated and input second point P2.
The distance is displayed on D5 and the distance between the first point P1 and the second point P2 is calculated (step S5 in FIG. 4C). In this way, calculating the distance between the designated and input first point P1 and second point P2 means that the measurement of the distance of a specific portion of the document image and the input of the measured distance are performed simultaneously. Means that

Next, the CPU 1 displays on the LCD 5 the operation guidance information "Input the length after scaling from the first point to the second point" (FIG. 4 (c), step S).
6). Therefore, when the length after scaling from the first point to the second point is input using the ten keys 62 (step S7), the CPU
1 displays the input length after scaling on the LCD 5 (FIG. 4 (d), step S8), and sets the scaling factor based on the distance between the first point and the second point and the length after scaling. It is calculated and set (step S9). Then, when the start key 64 is operated (step S10), the original image is copied at the calculated and set scaling factor (step S11).

As described above, the distance between a specific portion of the original image and the measured distance can be measured at the same time by simply designating two arbitrary points on the original image by the digitizer 61. In addition, it is not necessary for the user to measure the distance of a specific portion of the document image in advance using a ruler or the like, and further, the troublesome operation of inputting the measured numerical value with a ten-key or the like is eliminated, and the usability is improved. Moreover, since the operation guidance information and the like are sequentially displayed on the LCD 5, the usability is improved in this respect as well.

In addition, the operation unit 6 is the ten-key pad 6 as in the first embodiment.
2, the mode setting key 63, the start key 64, etc. are provided, but the digitizer 61 is not provided.

In the second embodiment, the CPU 1 is
Original image data input from the scanner and stored in the RAM 12 is read out and displayed as a preview image M on the LCD 5 as shown in FIG.

In this way, the preview image M is displayed on the LCD 5.
In the state where is displayed, the CPU 1 first displays the operation guidance information “specify a rectangular area” on the LCD 5, as shown in FIG. Therefore, a rectangular area is arbitrarily designated by a touch operation on the preview image M displayed on the touch panel type LCD 5. Note that this rectangular area can be specified by specifying two points, as in the first embodiment, by specifying the diagonal positions of the rectangular area.

When the rectangular area is designated in this way, the CPU 1 displays on the LCD 5 the operation guidance information "Enter the length of the rectangular area after XY scaling". Therefore, in the X direction after scaling of the specified rectangular area,
Input the length in the Y direction with the ten keys 62. Then,
The CPU 1 calculates the lengths of the designated rectangular area in the X and Y directions, and calculates and sets the scaling factor based on the calculated length and the input length after scaling. When the start key 64 is operated, the original image is copied with the calculated and set scaling factor. Therefore, also in the second embodiment, similarly to the first embodiment, it is possible to simultaneously measure the distance of a specific portion of the document image and input the measured distance. Further, as an effect peculiar to the second embodiment, an inexpensive touch panel type LCD is used without using an expensive digitizer.
Since, is used, the cost increase rate can be reduced.

The present invention is not limited to the above embodiment,
For example, the length after scaling may be specified by a digitizer or a touch panel LCD without inputting the numerical value itself with the ten keys.
