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

(First Embodiment) First, a first embodiment of the present invention will be described with reference to the accompanying drawings. This embodiment is an embodiment using a personal computer as an image display device. FIG. 1 is a block diagram illustrating a schematic configuration of the image display device according to the present embodiment.

The computer 1 as an image display device includes:
As shown in FIG. 1, a CPU 10, an input / output I / F (interface) 11, a ROM 12, a RAM 13,
The system includes a hard disk 14, a bus 15, display means 16 such as a CRT, and input means 17 for inputting an image such as a scanner device.

The ROM 12 is a memory in which data necessary for processing in the computer 1 and a program for starting an operation system stored in the hard disk 14 are stored.

The RAM 13 is a memory for temporarily storing data and the like necessary for processing in the CPU 10, and outputs the data to the bus 15 as necessary. Hard disk 1
4 may also be used as an area for transferring the application program stored in the application program 4. Further, it is also used as a storage area for display data to be displayed on the display means 16.

The hard disk 14 is a storage device for storing an operation system or an application program. In the present embodiment, the print servers 2 and 3 are provided with UNIX as an operation system. In the present embodiment, the print data is also stored in the hard disk 14.

The CPU 10 performs its own arithmetic processing based on the operation system or the application program, or controls each of the components connected via the bus 15 to perform the functions described in the flowcharts described later. Is executed.

The input / output I / F 11 is a means for controlling the interface between the display means 16 and the input means 17 and the CPU 10. The input / output I / F 11 causes the display means 16 to display the display data developed on the RAM 13 or from the input means. The input instruction is output to the CPU 10.

In the above system, when an application program for image processing is started,
It is configured to be capable of inputting an image by the input means 17 and converting the input image.

As an example of the conversion processing, there is an enlargement / reduction processing. FIG. 2 shows an aspect of an image displayed on the display means 16 when such a conversion process is performed. FIG.
(B) is a reference image of the size read first,
FIG. 2A is an image obtained when the reference image is reduced by 50%, and FIG.
It is an image at the time of performing magnification of%.

The enlargement / reduction processing of this embodiment is performed as follows. FIG. 3 shows a pixel region in a bitmap area formed on the RAM 13 in the present embodiment, and one pixel region is constituted by 64 8 × 8 pixels. In FIG. 3, the value written to each pixel is the number of each pixel. A bitmap area having such a configuration is provided for each color of red, green, and blue (R, G, B), and a color level value of, for example, 256 gradations is written in each pixel of the bitmap area of each color. , 2
A 56-gradation full-color image can be displayed on the display unit 16.

Here, assuming that there is an image drawn in an 8 × 8 pixel area as shown in FIG. 3, an example in which this image is enlarged twice will be described. FIG. 4 shows this pixel area as 2
This is an example that is doubled. As described above, the data of each pixel is copied to three pixels adjacent to the pixel, and drawn using twice the pixel area in each of the x direction and the y direction, and further, in the diagonal direction.

For the reduction, the reverse process may be performed. For example, assuming that there is an image drawn in a 16 × 16 pixel area, to reduce this image by half, FIG.
A process of thinning out pixel data is performed as shown in FIG. However, the enlargement / reduction processing described here is merely an example, and an appropriate enlargement / reduction processing can be used in the present invention.

An image display device for performing such enlargement / reduction processing has been put to practical use, but in the conventional device, the image is enlarged only by looking at the image displayed on the display means. It has been difficult to determine whether the image has been reduced or reduced. Furthermore, even if you know that the image has been enlarged or reduced intuitively or from the background of the operation, just looking at the image,
It was not possible to immediately determine what enlargement or reduction ratio was reached.

Therefore, in the present embodiment, as shown in FIG. 2, a frame image as a displacement index image is displayed around the display image, and the color of the frame image is further changed according to the rate of change of enlargement or reduction. It was configured to be changed according to.

For example, when the color of the frame of the reference image is set to black, the color of the frame is changed to blue when the image is reduced at the smallest reduction ratio, and when the image is reduced at the largest expansion ratio. Is configured to change the color of the frame to green.

That is, in the present embodiment, the color of the frame is red,
Green and blue (R, G, B) are designated by 256 gradations, respectively. When the magnification is 0%, the blue value is 255,
The values of red and green are set to 0%.
It is configured to reduce the blue color by 55/100. With this configuration, when the magnification is 100%, red, green,
The values of blue are all 0, and the color of the frame is black.

When the enlargement ratio is set to 100% or more, the value of red is increased by 255/100. As a result, the value of red becomes 255 when the enlargement ratio is 200%, and the color value of the frame is not changed when the enlargement ratio becomes higher.

In this embodiment, since the frame is configured as described above, the color of the frame continuously changes in accordance with the enlargement ratio, and the enlargement ratio is immediately determined only by checking the color of the surrounding frame together with the display image. It is possible to

Further, the thickness of the frame line may be changed according to the enlargement ratio. For example, at a magnification of 0-99%,
The thickness of the frame line may be 1 pixel, 2 pixels when it is 100%, and 3 pixels when it exceeds 100%.

Further, the type of the frame line may be changed according to the enlargement ratio. For example, a configuration may be adopted in which a dotted line is displayed when the magnification is 0-99%, a solid line is displayed when the magnification is 100%, a dashed line is displayed when the magnification is 100% -200%, and a line is blinked when the magnification exceeds 200%.

Note that the frame shown in FIG. 2 is drawn with a different pattern, but this represents a difference in color, and such a pattern is not displayed. However,
The pattern may be changed in this manner.

Next, the image display processing in this embodiment will be described with reference to the flowchart of FIG.

First, an enlargement ratio of an image is designated by input from a keyboard or the like (not shown) (step S30).
Next, the image is enlarged to the designated resolution (step S
31). This processing is the processing described with reference to FIG. 3 and FIG.
This is performed by expanding the drawing data using. Then, the color, thickness, and type of the frame line are designated (step S3).
2). Next, the developed image is written in a display area formed on the RAM 13, and a frame is drawn based on the specified color, thickness, and type, thereby displaying the image and the frame as shown in FIG. Step S33). The frame may be drawn by storing basic drawing data such as font data in the ROM 12 or storing control commands such as a page description language on the hard disk 14.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to the accompanying drawings. In the present embodiment, as shown in FIG. 6, an image is rotated or horizontally inverted. FIG. 6A shows the original image, and FIG.
FIG. 6B is an image rotated 90 ° to the left, and FIG. 6C is an image inverted left and right.

FIG. 7 is a diagram showing the state of the pixels on the bitmap area when the image shown in FIG. 3 is turned 90 degrees to the left. Thus, a rotation of 90 ° translates the y coordinate axis into x
This is realized by transforming the coordinates of each pixel so as to be coordinate axes. FIG. 8 is a diagram illustrating a state of each pixel when the pixel is inverted right and left. Thus, left-right inversion is
This is realized by moving the coordinates of each pixel line-symmetrically with respect to the y-coordinate axis.

Then, also in the present embodiment, the display state of the frame is changed according to the rotation angle and the like. In the present embodiment, a clockwise rotation angle is indicated. For example, when the rotation angle changes from 0 ° to 90 °, the value of red is increased by 255/90 each time the 1 ° rotation angle increases. When the rotation angle changes from 90 ° to 180 °, the red value is decreased by 255/90 and the green value is increased by 255/90 every time the 1 ° rotation angle increases. Also, 1
When changing from 80 ° to 270 °, the green value is decreased by 255/90 and the blue value is increased by 255/90 each time the 1 ° rotation angle increases. Furthermore, 270 ° -3
When changing to 60 °, the value of blue is reduced by 255/90 each time the 1 ° rotation angle increases.

When the rotation angle is 0 ° -90 °,
When the rotation angle is 90 ° -180 °, the frame line is a dashed line, and when the rotation angle is 180 ° -270 °, the frame line is blinking with a solid line, and the rotation angle is 270 ° -360 °.
In this case, the frame may be configured to be a solid line.

When the rotation angle is 0 ° -90 °,
The thickness of the frame is 1 pixel, and the rotation angle is 90 ° -180.
In the case of °, the thickness of the frame line is 2 pixels and the rotation angle is 18
When 0 ° -270 °, the thickness of the frame line may be set to 3 pixels, and when the rotation angle is 270 ° -360 °, the frame line may be set to 4 pixels.

Hereinafter, the image display processing in this embodiment will be described with reference to FIG.

First, in the case of rotation, a rotation angle is designated by input from a keyboard or the like (step S40). Next, a process of rotating the image by the designated rotation angle is performed (step S41). This process is the process described with reference to FIG. Next, the color, thickness, and type of the frame line are designated according to the rotation angle (step S42). Then, the rotated image is written in the display area, and the designated color, thickness, and type of frame are also written in the display area, and the display means displays an image as shown in FIG. The above is the display processing according to the rotation.

Next, as another embodiment, the frame line may be set to a dotted line in the case of upside down, and the frame line may be flickered in the case of right and left inversion.

FIG. 10 shows a flowchart of the process in the case of inversion. First, the user designates upside down or left / right inversion by input from a keyboard or the like (step S50). Next, a process of inverting the image vertically or horizontally is performed (step S51). This process is the process described with reference to FIG. Next, depending on the mode of inversion, the color of the frame line,
The thickness and type are designated (step S52). Then, the rotated image is written in the display area, the designated color, thickness, and type of frame are also written in the display area, and the display means displays an image as shown in FIG. The above is the display processing according to the inversion mode.

As described above, according to the present embodiment, it is possible to immediately determine the rotation angle or the reversal mode just by looking at the color, thickness, and type of the frame.

In each of the embodiments described above, a case has been described in which a personal computer is used as an image display device. However, the present invention can be applied to any case of laying out images. it can.

For example, when data written in a page description language is transmitted to a printer and printed, a preview image is transmitted from the printer to a personal computer, and
This is applicable when displaying a preview image on a personal computer. In such a system,
The preview image is laid out on a personal computer, the preview image is arranged at an arbitrary position, the position, size, rotation angle, up / down or left / right inversion of the preview image are transmitted to the printer, and the printer prints as instructed I do. Therefore, by applying the present invention, it is possible to perform printing while displacing an image to a desired mode without fail.

The shape of the frame is not limited to a square shape, but may be any suitable shape. Further, a configuration in which a mark of a predetermined shape is displayed near an image without using a frame may be employed.

In the above-described embodiment, the case where the display processing control program of the present invention is recorded on a hard disk as a recording medium has been described.
It may be configured to be recorded on a recording medium such as a D-ROM and read by a computer or the like.
