Description

[0001]
[Industrial applications]
The present invention relates to a two-dimensional imaging scanner that captures image information in two dimensions, and more particularly, to a two-dimensional imaging scanner that displays the processing status of image information in an easily understandable manner.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a two-dimensional imaging type scanner using an imaging device such as a CCD device has been known as a device for reading image information (Japanese Patent Publication No. 4-75537).
FIG. 16 is a diagram illustrating an example of this type of two-dimensional imaging type scanner.
In the figure, a transparent window 52 is provided at a central portion of a reading table 51 arranged on a document, and position sensors 53 are arranged on both sides of the transparent window 52.
[0003]
A camera 54 is arranged above the transparent window 52, and a lamp 55 for illuminating a document is arranged near the camera 54.
In the conventional example having such a configuration, the operator places the reading table 51 on the document and captures the first image information. This first image information is displayed on a screen of an external monitor device (not shown).
[0004]
Next, the operator moves the reading table 51 while looking through the document through the transparent window 52 or the finder of the camera 54, and determines the second image capturing position, and then captures the second image information.
The position sensor 53 measures these imaging positions one by one. Based on the measurement values of these imaging positions, the origins O and O 'of each imaging position as shown in FIG. 17 are calculated, and the translation vector OO' is calculated from the movement amount and the movement direction. Further, the inclination θ of the coordinate axes at these imaging positions is calculated.
[0005]
By using the values calculated in this way, the second image information is translated by the translation vector OO ′ and further rotated by the inclination θ, so that the second image information has the same coordinates as the first image information. Linearly mapped on the surface.
After the first and second image information are combined as single image information on the same coordinate plane, the combined image is displayed on the screen of the external monitor device.
[0006]
[Problems to be solved by the invention]
By the way, in such a conventional example, it takes about several seconds to several tens of seconds to linearly map the second image information. Therefore, there is a problem that the operator cannot determine whether the process is being continued or stopped during that time.
[0007]
Usually, in a computer or the like, when performing such a time-consuming operation, the mouse pointer is changed to an "hourglass mark" and displayed, or the progress is displayed as a bar graph.
However, when these general-purpose displays are used in a two-dimensional imaging type scanner, an "hourglass mark" or the like is suddenly displayed immediately after an image of a document is taken, making it difficult for an operator who is unfamiliar with the operation to understand the processing status. However, there is a problem that it is often misunderstood that “imaging of a document has failed”.
[0008]
In addition, these general-purpose displays have a problem that it is not possible to immediately determine whether or not a desired position on a document has been imaged. Therefore, when the operator makes a mistake in the image capturing position of the document, it is necessary to wait until the mapping process is completed, make a determination, and perform the image capturing of the document again, resulting in poor operability.
Claim 1The object of the invention described in (1) is to provide a two-dimensional imaging scanner capable of improving the operability while displaying the processing status in an easy-to-understand manner in order to solve such problems.
[0009]
Claims 2-5Another object of the present invention is to provide a two-dimensional imaging scanner that accurately displays that the mapping process is ongoing, in addition to the above-described objects.
Claims 6 and 7Another object of the present invention is to provide a two-dimensional imaging scanner that accurately displays the progress of a mapping process, in addition to the above-described objects.
