The display device then displays the image in a rotated state compared to the initial state.

Problems to be Solved by the Invention However, in the above-mentioned conventional image display device, instructions are given to the image rotation device after confirming the image information displayed on the display section. When the vertical and horizontal directions are mixed, there is a problem in that the image information is displayed in a mixed state on the display section, making it difficult to read the image information.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide an image display device that always displays image information in a predetermined direction regardless of the direction of the paper being read.

Means for Solving the Problems In order to achieve the above object, the present invention includes an image reading means that reads an image, adds a mark to the read image according to the direction in which the image is formed, and outputs it as image information; mark identification means that identifies the position of the mark based on image information and outputs a rotation instruction signal according to the identification result; and image rotation that rotates the image information based on the rotation instruction signal and outputs it to a display section. It is characterized by comprising means.

Effects The present invention has the following effects due to the above configuration. That is, when the image reading means reads the image formed on the paper, it adds a mark corresponding to the direction of the paper and the image to the read image and outputs it as image information. This image information is taken in by the mark identification means, the marks provided in the image information are read to identify the direction of the paper and the image, and the identification result is outputted as a rotation instruction signal to the image rotation means. The image rotation means rotates the image information based on the captured rotation instruction signal and outputs the image information to the display section for display.

Embodiment FIG. 1 is a block diagram showing an image display device according to an embodiment of the present invention.

This image display device includes a scanner 1 as an image reading means that reads an image formed on a rectangular sheet of paper in a predetermined direction, and adds a mark corresponding to the direction in which the image is formed to the read image and outputs it as image information. , an image memory 2 that takes in image information from the scanner 1 and stores it;
and a mark identification unit 3 which takes in image information from the image memory 2, identifies the mark based on this image information (2), and outputs a rotation instruction signal according to the identification result; an image rotation unit 4 that performs processing such as rotation on the image information stored in the image memory 2 in a conversion area based on the rotation instruction signal outputted by the identification unit 3, and outputs this processed image information to the image memory 2; , image memory 2 (- connected,
It also includes a display section 5 that takes in processed image information input from the image rotation section 4 from the image memory 2 and displays it.

Specifically, the scanner 1 reads images and outputs image information as follows. That is, the scanner 1 is
The normal state is when an image is input in an erect state on a vertically long sheet of paper, and when the image is read in this state, a special mark is added to the erect image 11 as shown in FIG. 2(a). While outputting this to the image memory 2 as image information 12, if the image 13 tilted 90 degrees to the right is input, this tilted state is set at a predetermined position (lower right position in the figure).
Add the mark 14 shown in the image 13 to the image information 15, and if you input the image 16 tilted 90 degrees to the left, this tilted state will be set at a predetermined position (lower left position in the figure). The mark 17 indicated by is added to the image 16 (-) and is outputted to the image memory 2 as image information 18.

Ma/7 sense 51! II Iku 3 is described in 1. Image information 12
, 15.

18 is taken in through the image memory 2, the marking status is identified, and a rotation instruction signal is output in accordance with the identification result. That is, in the case of the image information 12, it is determined that no mark is attached, and a rotation instruction signal with the content "do not rotate" is determined, and in the case of the image information 15, the mark 14 is output.
Depending on the position of mark 17, a rotation instruction signal with the content "rotate 90 degrees to the left" can be generated, and in the case of image information 18, the position of mark 17 can generate a rotation support signal with the content of "rotate 90 degrees to the right". Output to rotating section 4.

The image rotation section 4 takes in image information from the image memory 2, and also performs rotation processing on the image information based on a rotation instruction signal taken in from the mark identification section 3. In this case, if the content of the rotation instruction signal is "not rotated", no data conversion is performed in the conversion area of the image rotation unit 4, and for example, the image information 12 in FIG. As shown in d), if the image information 12 is sent as is to the image memory 2, and the content is "rotate 90 degrees to the left", the conversion area will change the image information 15 in the same figure (b), for example. The image information 15 is then rotated 90 degrees to the right as shown in FIG.
If the content is "rotate 90 degrees to the right," the image information is rotated 90 degrees to the right in the same way. For example, the image information 18 shown in FIG. It is rotated as shown in f).

The operation of the image display device configured as above will be explained.

First, when a sheet of paper on which an image such as a text is formed is input to the scanner 11, the scanner 1 reads the image and marks the sheet by setting the position according to the direction in which the image is formed on the sheet. The mark is added to the read image, and the read image to which the mark is added is output to the image memory 2 as image information. The image information input to the image memory 2 is once stored there, and then taken into the mark identification section 3 and the image rotation section 4.

The mark identification section 3 identifies the mark in the captured image information, and outputs a rotation instruction signal to the image rotation section 4 in accordance with the identification result. Based on this rotation instruction signal, the image rotation section 4 performs rotation processing on the image information corresponding to this rotation instruction signal, and returns the image information subjected to rotation processing to the image memory 2 to be stored again. This stored image information is taken into the display section 5 and displayed.

In this embodiment, the case where all the image information taken into the image memory 2 from the scanner 1 is output to the image rotation unit 4 is used as an example, but the identification result of the mark identification unit 3 indicates that the image information is not rotated. The image information displayed may be stored in the image memory 2 as is. This simplifies the process.

Further, in this embodiment, after the rotation process of the image rotation unit 4,
Although the case where the image information is temporarily returned to the image memory 2 and stored is taken as an example, the image information may be directly sent from the image rotation section 4 to the display section 5.

In addition, in this embodiment, the normal state is when an image is formed on a vertically long sheet of paper in an upright position, and the case where no mark is added is taken as an example, but the image is formed in another direction. The normal state may be the case where
The shape of the paper and the input direction of the paper are also not limited to this example.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, the direction of the paper to be read is identified and the image information is rotated according to the identification result, so the image can be displayed in a fixed direction, making it easier to read the image. .
