Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image display control system, and particularly to an image of a form read by a scanner in a bank terminal or the like.

The present invention relates to an image display control method suitable for displaying images on a display.

[Conventional technology]

In recent years, financial institutions such as banks have been using seal verification devices and the like that utilize OCR, electronic files, and the like for the purpose of improving office efficiency. In these devices, an image of a form read by a scanner is displayed on a display to confirm the read image. Furthermore, OCR
In this method, the image of the part where character recognition was performed is displayed on the display along with the character recognition results to confirm the recognition results.

Conventionally, when displaying an image on this display, information related to the image, for example, address and two names.

Due to the need to display account numbers etc. on the same display,
Decide the display range of the image, decide the reduction ratio of the image so that it fits within the display range, and then reduce the image using that reduction ratio and display it on the display, or change the size of the image so that it fits within the display range. The device calculates the reduction ratio based on the display range and displays the image.

Note that related devices of this type include, for example, the device disclosed in Japanese Patent Application Laid-Open No. 60-220476.

[Problem to be solved by the invention]

The above-mentioned prior art lacks consideration to the fact that the purpose of display differs depending on the type of image to be displayed. For example, for items such as seal impressions that require high accuracy, it is necessary to display the image as it is read from the scanner without enlarging or reducing it. In the method of displaying images on a display, the magnification is set to 1 (
If the images are displayed at different sizes (at the same size), they will exceed the display range on the display, and characters etc. displayed on the same screen will be erased. Further, in a method in which the device automatically calculates and displays a reduction ratio according to the display range, there is a problem that if the size of the displayed image differs, the image cannot be displayed at the same size.

The present invention has been made in view of the above circumstances, and its object is to overcome the conventional technology. i: We have developed an image display control method that solves the above-mentioned problems and allows images to be displayed according to the display purpose and the display range, even if the types of images to be displayed are different. It is about providing.

[Means to solve the problem]

The above object of the present invention is to provide an image display device having a table representing the size of each input image, and a table representing the display position and display range of the image on the display. A table representing a display attribute indicating a display mode for each image is provided in correspondence with a table indicating a display position and a display range, and the display mode on the display is controlled by the contents of the attribute table. This is achieved using an image display control method.

[Effect]

In the image display control method according to the present invention, each display range has a display attribute, and the image display method is changed according to the designation of this display attribute.Thereby, the display method is changed depending on the type of image, etc. 5 It becomes possible to realize a display that matches the display purpose of each image.

In the form 1 shown in FIG. 3, the position information of the rectangular area 2 that is desired to be displayed on the display is set in the form cutout position information table 3. This setting method sets the horizontal distance (X) from the left edge of the document to the left edge of the rectangular area for each rectangular area on the document to the "horizontal coordinate of the left end of the rectangular area" 4.

Similarly, the vertical distance (Y) from the upper left end of the @ vote to the upper left end of the rectangular area is set to "vertical coordinate of left end of rectangular area" 5. In order to set the rectangular area, the rectangular area width (LX) is set to "rectangular area width" 6, and the rectangular area vertical length (LY) is set to "rectangular area length" 7. This is shown on Form 1.

The process is repeated as many times as there are rectangular areas to complete the @vote cutting position information table 3.

Next, the display rectangular area 15 is determined by considering the screen layout of the display screen 14 that performs display. The display rectangular area 15 is defined by the image display table 8. Specifically, the display position of the display is determined by the horizontal distance fi (XD
