Abstract

PURPOSE:To display the whole image information and, simultaneously, to recognize the actual size of the image information from a conversion ratio by converting the whole image information so as to be displayed on a display means and displaying the conversion ratio on the display means with a control means. CONSTITUTION:The size information of an inputted original and the display picture size of a CRT display 26 to be set beforehand are compared by a CPU 12. As a result of the comparison, when the size of the original is smaller than the display picture size of the display 26, the image information stored in a page memory 21 is supplied to an enlarging and reducing circuit 23, and the whole original image is reduced in a size displayable on the display picture of the display 26 by the circuit 23. The image information reduced by the circuit 23 is transferred to a display memory 22A, the image information stored in the memory 22A is read by a display control part 25, and it is displayed on the display 26. At such a time, a display ratio 26a such as '75%' is displayed along with image information ID in one part of the display picture of the display 26.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an information processing device that can display image information read from a document by, for example, an image reading device on a display device.

(Prior Art) In this type of information processing device, image information of a document read by a scanner device is temporarily stored in a buffer memory;
When displaying the image information stored in this buffer memory on a display device, the image information is transferred from the buffer memory to the display memory, and the image information stored in this display memory is displayed on the display device.

By the way, when displaying image information read by a scanner device on a display device, the size of the read document may not match the size of the display memory and the display screen of the display device.

In such cases, conventionally, the size of the image information has been converted so that the image information can be displayed on the display screen. In other words, when the size of the document is larger than the size of the display screen, the image information of the document is appropriately reduced, and when the size of the document is smaller than the size of the display screen, the image information of the document is appropriately enlarged and displayed. .

However, when displaying image information by appropriately enlarging or reducing it as described above, even when displaying image information such as a drawing on a display device and wanting to know the dimensions directly from the displayed drawing, it is difficult to actually It was not possible to know the dimensions of the

(Problems to be Solved by the Invention) This invention solves the problem that the actual dimensions of image information displayed on a display device cannot be known, and its purpose is to It is an object of the present invention to provide an information processing device that is capable of displaying the entire information as well as knowing the actual dimensions of the displayed image information.

[Structure of the Invention] (Means for Solving the Problems) The present invention includes a reading means for reading image information of a document, a display means for displaying the image information read by the reading means, and an image read by the reading means. The information is
If the image information is larger than the display size of the display means, it is comprised of a conversion means for converting the entire image information into a size that can be displayed on the display means, and a control means for displaying the ratio converted by the conversion means on the display means.

(Operation) When the image information of a document read by the reading means is displayed on the display means, when the size of the image information is larger than the display size of the display means, the conversion means displays the entire image information on the display means. Convert so as to obtain, and
Since this conversion ratio is displayed on the display means by the control means, the entire read image information can be displayed on the display means, and the actual dimensions of the displayed image information can be known from the conversion ratio. It is something that can be done.

On the other hand, the read image information is displayed on the CRT display 2.
When displaying on θ, the CPU 12 compares this input document size information with the preset display screen size of the CRT display 2B (Sr1.3).
. As a result, if the size of the document is smaller than the display screen size of the CRT display 26 and it is possible to display 100% of the image information of the document on the display screen, the image information stored in the page memory 21 will be transferred to the display memory 22A. (Sr4). The image information stored in the display memory 22A is read out by the display control unit 25 and CR
displayed on the T-display 26 (5T5). Also,
At this time, as shown in FIG. 3(a), a part of the display screen of the CRT display 2B displays "
100%" display ratio 28a is displayed (<5TY).

Furthermore, as a result of the comparison (Sr1.3), the size of the document is larger than the display screen size of the CRT display 26;
When it is impossible to display the image information of the original on the display screen, the image information stored in the page memory 21 is supplied to the enlargement/reduction circuit 23, and the entire original image is displayed on the CRT in this enlargement/reduction circuit 23. Display 2B
will be reduced to a size that can be displayed on the display screen (5T7
). The image information reduced in this enlargement/reduction circuit 23 is transferred to the display memory 22A (Sr8), and the image information stored in this display memory 22A is transferred to the display control unit 25.
is read out and displayed on the CRT display 26 (5T9). Also, at this time, as shown in FIG. 3(b), a part of the display screen of the CRT display 26 is displayed.
Along with the image information ID, display ratio 2[1] such as "75%"
a is displayed (STIO).

According to the above embodiment, when displaying the image information read from the scanner 27 on the CRT display 2B, if the document size is smaller than the display screen of the CRT display 26, the display ratio is set to "100%" and the image information is displayed as is. Image information is displayed on the CRT display 26, and if the document size is larger than the display screen of the CRT display 26, the enlargement/reduction circuit 23 reduces the entire document image to a size that can be displayed on the display screen, and then reduces the image at a predetermined display ratio. The image information obtained is displayed on the CRT display 26. Therefore, the entire read image information can be displayed on the CRT display 26, and from the display ratio, it can be immediately known whether the image information displayed on the CRT display 26 is displayed in its original size. It is.

Moreover, if you want to know the actual dimensions of the image information displayed on the CRT display 2B, you can measure the length of the displayed image with a ruler and divide this measured length by the display ratio. It allows you to know the dimensions and accurately display the image information read from the original.
It is something that can be done.

Note that this invention is not limited to the above embodiments,
Of course, various modifications can be made without departing from the gist of the invention.

[Effects of the Invention] As detailed above, according to the present invention, the entire image information can be displayed on the display means, and since the conversion ratio of the image information is displayed on the display means, It is possible to provide an information processing device that can know the actual dimensions of image information.
