Abstract

PURPOSE:To segment only a required part by designating an area address by data from a digitizer, and validating only the data in a designated area by using a CCD position detection circuit to recognize the position of a CCD device. CONSTITUTION:The CCD device 5 is assembled in the same mechanical manner as that of the CCD device 1 which performs the reading of an image from a document and a newspaper, etc., and reads in a position designation scale 11 assembled in the digitizer 6. An original 13 such as the document or the newspaper is placed on the digitizer 6, and pressure by a pen is applied at the position where is desired to read. Thereby, a control circuit 8 recognizes the position of a read area 12, and generates position data, and transmits the position data. And the data in an area other than the designated area at a gate circuit 9 out of the data accumulated in a memory circuit 2 is assumed as the one in states where no character, etc., exists, and is converted to white data.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an image scanner device trap for inputting image data to a personal computer, and in particular, it processes captured data into only necessary information by specifying an area. The present invention relates to an image scanner device that outputs images.

(Prior Art) Conventionally, as shown in FIG. 3, this type of image scanner device has a CCD element 1 for reading data as image information from documents, newspapers, etc., a memory circuit 2 for storing the read data, This system consisted of a compression circuit 3 for efficiently sending data to a personal computer and a transmission circuit 4, and all read data was sent to the personal computer.

(Problem to be solved by the invention) In the conventional image scanner device mentioned above.

Although the read data is reduced by a compression circuit, unnecessary data is also transmitted, which has the disadvantage of increasing the amount of data stored in the 1K personal computer.Secondly, the amount of data stored in the personal computer increases This method has the disadvantage that additional processing is required, which places a burden on the operator. Third, it takes a long time to transmit data.

The purpose of the present invention is to eliminate the above drawbacks by specifying the reading position with a digitizer, validating only the area specified by the digitizer in the read data, and recognizing the positional relationship with the digitizer with a CCD position detection circuit. And the amount of data is 33! It is an object of the present invention to provide an image scanner device flt which is configured such that it is possible to increase the amount of power.

(Means for Solving the Problems) An image scanner device according to the present invention has at least %OO
It is equipped with a D element, a memory circuit, a compression circuit, and a transmission circuit, and is for collecting image information from documents, newspapers, etc., and is equipped with a digitizer, a gate circuit, and a CCD position detection circuit. This is what I did.

The digitizer is used to input the designation of the position of the thread removal.

The gate circuit is for validating data only in the area designated by the digitizer.

The CCD position detection circuit is for detecting a specified position on the OOD element.

(Example) Next, one embodiment of the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an image scanner device according to the present invention, and FIG. 2 is an external view of the image scanner device shown in FIG. 1.

1 and 2, the IFi first CCD element, 2 a memory circuit, 3 a compression circuit, and 4 a transmission circuit, these elements are the same as the conventional one explained in FIG. It is. Further, 5 is a second CCD element, 6 is a digitizer, 7 is an area address generation circuit, 8 is a control circuit, 9 is a gate circuit, 10 is a position detection circuit (001), 11 is a position specifying scale, 12 is a reading area, 13 is a manuscript.

The second CCD element 5 reads images from documents, newspapers, etc. Mechanically, it is built in the same way as the first CCD element 1, and reads the position designation scale 11 built in on the digitizer 6. . Here, a document 13 such as a document or a newspaper is placed on the digitizer 6, and pressure is applied from a pen or the like to the position on which reading is to be performed around the area shown in FIG.

Thereby, the control circuit 8 recognizes the position f of the reading area 12, generates position data, and transmits the position data.

The position data from the digitizer 6 is read by the area address generation circuit 7, converted into range data, and transmitted to the control circuit 8. Upon receiving the data from the area address generation circuit 7, that is, the data of the position designation scale 11 on the digitizer 6 read in advance, the control circuit 8 outputs OOD.
Data is read from the second CCD cumulator 5 via a CCD position detection circuit 10i for detecting the digit t of elements 1 and 5.

As a result, five of the data stored in the memory circuit 2,
All areas other than those specified by the gate circuit 9 are treated as having no characters and are converted to white data. Therefore, only the data within the designated area is sent to the compression circuit 3 as information. The data is thereby compressed, and the compressed data is transmitted from the transmission circuit 4 to the personal computer.

(Effects of the Invention) As explained above, the present invention specifies an area address using data from a digitizer that can specify a reading area, and uses data from a CCD position detection circuit that recognizes the position t of a CCD element to detect the specified area. Enabling only the data is effective in that it is possible to extract only the necessary parts when importing image information from documents, newspapers, etc. Therefore, only necessary information is sent to the personal computer, and editing by the personal computer becomes easier. Furthermore, since only necessary data is transmitted, the transmission time can be reduced.
