Abstract

PURPOSE:To make temporary read-out unnecessary by designating the origin of an original before reading the original, and next, designating a desired reading range on the original. CONSTITUTION:When coordinate data is inputted from a coordinate input means (mouse) 2, a control part 1 consisting of a CPU, etc., makes a storage part 3 store this coordinate data, and simultaneously, it shows the reading range to a display means 4 by a rectangular frame. Here, before the original is read by a reading part 5, first of all, the origin of the original is designated by the coordinate input means 2, and next, the desired reading range is designated on this original by the coordinate input means 2. Thus, the original need not be read temporarily before it is read, and the range desired to read can be designated in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a reading range designation method, and more particularly to a reading range designation method for reading image data of a desired reading range on a document surface using an image input means.

Conventional technology Conventionally, in this type of reading range specification method, the -R document is first reduced to a size that fits on the screen, temporary reading is performed, the entire document is displayed on the screen of a personal computer, etc., and then the mouse or keyboard is used. Specify the range on the screen using etc.

To explain using the flowchart shown in FIG. 3, first, the entire document is read (step 200), and the input image data is displayed on the CRT screen. (Step 21o
) Next, a necessary reading range is specified on the CRT screen (step 220), the specified range of the document surface is read (step 230), and the read image data is displayed on the screen. (Step As described above, in the conventional reading range specifying method, before reading a document with a specified reading range, it is necessary to first read the entire document as a preliminary read and then specify the reading range.

Problems to be Solved by the Invention In the conventional reading range specifying method, in order to read the desired range, it is necessary to read the entire document once as a preliminary reading, which takes time and man-hours.

Therefore, an object of the present invention is to provide a reading range specification method that does not require temporary reading. specifying the origin of the original using coordinate input means;
Next, a desired reading range is designated on the original by the image input means, and then image data of the desired reading range of the original is read by the image input means.

Furthermore, before reading the original, the origin of the original is designated by the coordinate input means, and then a desired reading range is designated on the original by the image input means, and this desired reading range is within the display surface of the display means. According to the present invention, before reading the original, first the origin of the original is read. is specified using the coordinate input means, and then a desired reading range is specified on the document using the image input means, so temporary reading is not necessary.

Embodiment Next, a first embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 1, when coordinate data is input from a mouse 2, which is a coordinate input means, a control section 1 constituted by a CPU etc. stores this coordinate data in a storage section 3, and also stores the coordinate data in a display means 4. The reading range is indicated by a rectangular frame.

FIG. 2 shows the designation of the reading range in this embodiment.

This will be explained using FIG.

As shown in FIG. 2, the upper left corner (■) of the document is designated as the origin of the coordinates of the image data read by the image input device.

Next, specify the upper left ■ which is the starting point of the range you want to read, and then specify the lower right ■ which is the end point of the range you want to read.

If you specify the reading range on the document surface as described above, the third
As shown in the figure, on the CRT screen which is the display surface of the display means 4, the apex is +21. It is displayed in a rectangular frame with +31.

The rectangular frame on the CRT screen indicating this reading range is
It changes in proportion to the size of the reading range on the document.

For example, in Figure 2, if you specify the starting point as ■ and the end point as ■', the vertex will be +2 on the CRT screen shown in Figure 3.
), +31' is displayed in a rectangular frame.

Next, the operation of specifying the reading range in this embodiment will be explained in the fourth step.
This will be explained using the flowchart shown in the figure.

First, use the mouse 2, which is the coordinate input means, to specify the reference point on the document surface that will be the origin of the image data.Step 1
00), store the coordinate data of this reference point in the storage unit 3 (step 110), and then use the mouse 2 to specify the upper left position of the reading range on the document surface, which is the starting point of the image data. (Step 120) Calculate the distance from the origin using the control unit 1 based on the amount of movement of the mouse 2 from this reference point.Step 130) and store it in the storage unit 3.Step 140) - Next, use the mouse 2 to calculate the distance from the origin. Specify the lower right position of the reading range on the document surface as the end point. (Step 150) Next, a reading range is calculated based on the amount of movement of the mouse 2 from the upper left position to the lower right position of this reading range, and is stored in the storage unit 3 (Step 160). (Step 17
0) The reading position and range data stored in the storage section 3 is transmitted to the reading section 5 by the control section 1. (Step 180) As described above, the specification of read @surrounding is completed, and after this,
The reading section 5 can read image data in a desired range.

Next, a second embodiment of the present invention will be described with reference to FIG.

In this embodiment, as shown in FIG. 5, a rectangular frame on the CRT screen indicating the reading range is displayed with scales provided at predetermined fill intervals.

Effects of the Invention As described above, according to the present invention, there is no need to perform temporary reading before reading the original, so it is possible to specify the range to be read in a short time.
