JPS58182370A - Extracting device of picture information part - Google Patents

Abstract

PURPOSE:To extract only picture information in a designated region and to output it, by key-inputting an address of a required region, converting it into a main scanning address and a sub-scanning address of a scanner, inputting it to a control circuit, and comparing the address with the scanning address of an actual scanner. CONSTITUTION:Picture information (h) only in the designated region on an original 2 is outputted from a picture information selecting circuit 5, and when the sub-scanning position of a scanner 7 reaches a Y3 position, since a designated address is coincident with the sub-scanning address of the scanner 7 from an address memory 4, a control circuit 6 makes a skip signal (e) to ''H''. Thus, the scanner 7 starts high speed scanning again, and the scanning is finished when the scanner reaches the end position of the original 2. Thus, the picture information (h) of required part only is extracted from the original 2 from a picture information selection circuit 5 and outputed to a processing circuit of the next stage.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is suitable as an input device for a document creation device having an editing function such as a facsimile or an intelligent copier.
The present invention relates to an image information partial extraction device that extracts only necessary image information from a document.

Conventionally, in order to extract only the necessary image information from the original,
A mark area is created along the edge of the document in the sub-scanning direction, a mark is placed there, an extraction range is specified, this is detected by the scanner, and only the image information in that range is extracted. Was.

However, with this method, marks must be placed on the original, so the original becomes dirty, and if the same original is read sequentially with different extraction locations, the previous mark must be erased and the new mark added. However, there was a problem in that the work was complicated.

In order to eliminate this problem, attempts have been made to insert the original into a transparent sheet and mark it on that sheet, but even with this method, there is still the work of erasing the previous marks, and the sheet If there is a misalignment between the
There was a problem that required parts could not be extracted.

In addition, in any of the above methods, since the completed image information extraction area is detected by the scanner, the mark must be placed in a mark area that can be clearly distinguished by the scanner, and as a result, it is not possible to specify the area in the main scanning direction. However, there are drawbacks such as the fact that the extraction location is -dimensional only in the sub-scanning direction, which limits the editing work.

SUMMARY OF THE INVENTION The present invention provides an image information partial extraction device that eliminates the drawbacks of the prior art and is capable of extracting image information from necessary locations two-dimensionally in the main scanning direction and the sub-scanning direction without staining the original at all. Purpose @ To achieve this purpose, the present invention is to write a document on a transparent sheet document with ruled lines for specifying addresses in the X-axis and Y-axis directions, manually enter the address of the required area, This is converted into the main scanning address and sub-scanning address of the scanner, inputted to the control circuit, and compared with the actual scanning address of the scanner. The feature is that only image information is extracted and output.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 is an address designation key, 4 is an address memory, 5 is an image information selection circuit, 6 is a control circuit, and 7 is a scanner.

As shown in Fig. 2-), this address sheet l has ruled lines printed along the x and Y axes on a transparent film such as plastic, and furthermore, the ruled line ends Vc and the addresses XO to X5, Y The axial address sea Y6 is leveled.

To extract only necessary image information from a document, first, the address sheet 1 is superimposed on the document 2 as shown in (b), and the address of the image information portion to be extracted is read. for example,
If you want to extract only the image information in the diagonally shaded area surrounded by Ka = d as shown in (a), read the address (Xi, X3°Y2.Y3) of the area surrounded by the X and Y axes1.
Next, the address is inputted using the address designation key 3.

Due to this busy schedule, the address specification key 3 is pressed to input the address x (
Xi, X3. Y2. Y3) t-corresponding Srus'P yaf-
The scanning address of tb scanner 7 in the main scanning direction and the sub-scanning direction pit position l1iVc are respectively converted. The address memory 4 latches this converted scanning address, which is output from the control circuit 6, using the child signal a, and supplies the address bt to the control circuit 6.

Next, place the original 2 on the original reading device in the same manner as before,
When the start is applied, the control circuit 6 counts the element clock cl from the scanner 7 to create a line sync d'' for each scanning line, and further counts the line sync di to set the sub-scanning direction address designation key of the scanner 7. , when the sub-scanning address corresponding to Y2 inputted from the address memory 4 is incorrect, the skip signal -"1rLJic is dropped as shown in the time chart of FIG.

Accordingly, until the scanner 7 reaches the Y2 position,
Move the scanning position at high speed based on the skip signal ・Y2
When the speed is slowed down to 11, the skip signal falls by rLJK, and the reading speed returns to normal and main scanning is performed.

However, until the scanner 7 moves to the X1 position, the actual main scanning direction address and the address corresponding to X1 inputted from the address memory 4 do not match, so the control circuit 6 uses the address selection signal -ftrLJ. Therefore, the image information selection circuit 5 does not output image information tt during that time, but eventually, when the main scanning direction address of the scanner 7 also matches the address corresponding to Xl input from the address memory 4, the control circuit 6 outputs the address selection signal f. rHJ, the image information selection circuit 5 outputs the image information gffi output from the scanner 7 to the next stage processing circuit.

This state IIFi continues until the scanner 7 reaches the X3 position, and when the main scanning address of the scanner 7 and the address corresponding to X3 in the address memory 4 match, the control circuit 6 lowers the address selection signal f to "L" again. Therefore, the image information selection circuit 5 also stops outputting.

By repeating the above operations, only the image information of the designated Ryoko on the Fi original 2 is output from the image information selection circuit 5, and the sub-scanning position of the scanner 7 eventually reaches the Y3 position. When the specified address from the address memory 4 to 6 matches the sub-scanning address of the scanner 7, the control circuit 6 sets the skid/de signal e to "H", thereby causing the scanner 7 to start high-speed scanning again. Then, when the end position of the original document 2 is reached, the scanning ends.

In this way, the image information selection circuit 5 can extract only the necessary image information from the #'i document 2 and output it to the next stage processing circuit. Therefore, in the case of a facsimile machine, this image information is compressed and transmitted, and the receiving side receives it on the paper necessary to combine the information, so that, for example, the amount can be written on a slip and a bill can be sent. Edited documents can be obtained by performing tasks such as creating documents. In addition, in the case of an intelligent copier, an edited copy can be obtained by temporarily storing the image information in the RAM, combining it with necessary documents, and outputting it to a recording device.

It is clear that the necessary image information portion is not limited to one location from the original document 2 described in the above embodiment, but may be extracted from a plurality of locations at the same time.

In addition, as shown in FIG. 4, the address sheet 1 can be created by entering numbers in the squares in a color that makes it easy to see the document below, specifying the location to be extracted with these numbers, and inputting this using the address designation key 3. , it may be converted to address b similar to the above embodiment.

Further, in the above embodiment, the main scanning of the scanner 7 from the X-axis and Y-axis direction addresses specified by the address sheet 1,
Although the conversion to the sub-scanning address is performed using the address designation key 3, it goes without saying that this conversion work may also be performed using the control circuit 6.

As described above, according to the present invention, when reading a document with a scanner, it is possible to freely select the extracted portion two-dimensionally and extract only necessary image information from the document without staining the TW document. become able to.
