Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an image parameter processing device in an image reading device that determines an image reading area.

2. Description of the Related Art Generally, in order to determine an image reading area using an image parameter processing device, a two-dimensional coordinate system is considered from the physical origin of the scanner mechanism of the image reading device, and the coordinates of two opposing vertices of the document to be read are determined. A possible method is to input values from a data input section or the like and determine the image reading area based on the coordinate values, and use a numeric keypad, a digitizer, etc. as a means for inputting the coordinate values of the two vertices. However, image parameter processing devices that use this type of system need to accurately grasp the positional relationship between the physical origin and the document to be loaded, which makes it difficult to improve the accuracy of the reading position and also makes it difficult to operate. It also becomes ghastly. As a method to overcome this drawback, an image parameter processing apparatus has been devised, as shown in FIG. 2, which uses a mount for mounting a document on an image reading apparatus (this is called a carrier sheet) to perform reading and determine an area.

In FIG. 2, the carrier sheet 20 is made of paper with low elasticity and good transparency, such as a Mylar sheet, and a registration mark indicating the physical origin when the carrier sheet 20 is installed in the scanner mechanism of an image reading device is shown. The carrier sheet 20 is printed with a cross symbol 21, a frame 22 indicating the readable range, and a scale 23 to make the coordinate values easier to read. A register pinhole 24 is provided for mounting. On the other hand, a register bin that matches the register pinhole 24 is attached to the scanner mechanism section of the image reading device, and when the carrier sheet 20 is attached, the physical origin of the scanner mechanism section of the image reading device and the cross symbol of the carrier sheet 20 are attached. 21 are exactly matched. To specify the image reading area with an image parameter processing device using such a carrier sheet, you can paste the original onto the carrier sheet and read the coordinate values of its two vertices and enter them using the numeric keys, or use the digitizer to etc., to read the coordinate values of two vertices.

Generally, when an image is handled by a computer or the like, the amount of data is enormous. For example, if the area necessary for image processing is extracted using software, a large amount of processing time is required, which increases the load on the computer. Therefore, it is necessary for the image reading device to have a function of accurately trimming and reading the area to be processed. Furthermore, in many cases, the output size is predetermined, and image parameter processing apparatuses have conventionally existed that have a function of trimming and reading according to the output size.

A conventional image parameter processing device will be described below with reference to the block diagram of FIG.

In FIG. 3, 30 is a parameter input means for inputting the output size, and 31 is 2 of the opposite vertices of the document to be scanned.
A coordinate input flat membrane 32 for inputting point coordinate values is the same center of gravity inscribed in a rectangular area having the two point coordinate values as vertices, which is similar to the rectangle formed by the output size from the output size and the two point coordinate values. a vertex coordinate value determining means for determining the input area of the document whose largest rectangular area is to be scanned, and determining two vertex coordinate values of the input area; 33 sends out the two vertex coordinate values from the vertex coordinate value determining means 32; It is a data transfer means.

When performing trimming to match the output size in the vertex coordinate value determining means 32 in such a conventional image parameter processing device, if the image reading area specified by the operator is larger than the rectangular area formed by the output size, the specified image reading The coordinate values of the two vertices of the input area were determined so that the left and right or top and bottom sides of the protruding area were evenly cut out and read.

Problems to be Solved by the Invention However, as mentioned above, in the conventional image parameter processing device, the image reading device side cuts out the left and right or top and bottom portions of the protruding portion evenly and reads the area, so that the area to be subjected to image processing can also be processed. There were also cases where it was cut off [2, causing inconvenience to the operator. The object of the present invention is to trim/gage a rectangular input area specified by an operator without cutting it.

By providing this, the above objective is achieved.

According to the present invention, with the above configuration, the output document size calculating means has the same ratio between the output document size in the vertical direction and the manual document size in the vertical direction, and the ratio between the output document size in the horizontal direction and the input document size in the horizontal direction. For example, if the output document size in the vertical direction is input manually, the output document size in the horizontal direction is calculated, or if the output document size in the horizontal direction is input, the output document size in the horizontal and vertical directions is calculated. By determining the , fir and horizontal output document sizes, it is possible to trim without cutting out the rectangular manual area specified by the operator.
