Abstract

PURPOSE:To extract and optional reduction or enlargement to a picture and an optional area by providing a thinning out and an enlargement sampling clock generating part and a control part for designating a generating pattern with respect to the generating part. CONSTITUTION:The picture data of a binary time series obtained by scanning a reading picture by a picture reading part 1 is compressed in a band in an encoding and decoding part 3 and transmitted to a line 100. The picture data inputted from the line 100 is extended in the encoding and decoding part 3 and recorded in a picture recording part 2 as a receiving and recording picture of a hard. A thinning out and enlargement sampling clock generating part 5 generates a sampling clock capable of writing corresponding to a reduction and an enlargement of an optional ratio and an extract of an optional area. An operating part 7 designates the ratio to be reduced and enlarged and the area to be extracted respectively and a control part 6 controls a generating pattern according to the designation of the operating part 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device, and more particularly to a facsimile device that reduces or enlarges a read image and transmits it, and also reduces or enlarges a received image and records it.

[Conventional technology]

Conventionally, in this type of facsimile machine, the transmitter side reduces or enlarges a read image in the main and sub-scanning directions to match the recordable size of the receiver and then transmits the image. To perform reduction or enlargement, the binary time-series image data output from the image reading section is stored in a read-only memory (hereinafter referred to as R, OM).
Alternatively, the sampling clock is fixedly thinned out or expanded using a sampling clock generated from a sampling clock generator configured with random logic or the like.

[Problem that the invention seeks to solve]

In conventional dual facsimile machines, the sampling clock generator for reducing or enlarging the binary time-series image data from the image reading section is composed of random logic, and the Since changes are not possible, if you try to have a large number of reduced or enlarged patterns for image data, the ROM or random loss will increase, and furthermore, it will be difficult to generate arbitrary reduced or enlarged patterns or reduce any area. There is a drawback that it cannot be enlarged.

[Means for solving problems]

The facsimile device of the present invention has a function of reducing or enlarging image data in the main and sub-scanning directions, and a "non-printing clock" that allows rewriting the reduction or enlargement ratio of the image data and the area to be extracted. A thinning/enlarging sample link clock generator ``q'' that generates a decimating/enlarging sample clock, and a control means for specifying a generation pattern of the sampling clock for the thinning/enlarging → non-printer clock generating means. .

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block IA of an embodiment of the present invention, and FIGS. 2 and 3 are diagrams showing enlarged images of arbitrary areas without showing a read image in this embodiment.

In this embodiment, the image reading section], the image recording section 2, the encoding/decoding section 3, the line control section 4, the decimation/enlarged sampling clock generation section (the thinning clock generation section) 5, the control section 6, and the operation section 7 Has [2].

Binary time-series image data number obtained by scanning the image read by the image reading unit 1, encoded, band compressed by the decoding unit 3, and sent to line 00 via the line control unit 4 Sent out. Conversely, image data input from the line 100 via the line control unit 4 is decompressed by the encoding/decoding unit 3G and recorded in the image recording unit 2 as a received heart image. Furthermore, in the configuration of this embodiment, the sampling clock generator 5 is a part that generates a sampling clock that can be rewritten in response to reduction/enlargement of an arbitrary ratio and extraction of an arbitrary area, and the operation part 7 is
There is a section for specifying the ratio to be enlarged and the area to be extracted, and furthermore, the control section 6 is a section for controlling the generation pattern of the Zamp Link Crop generation section 5 according to instructions from the operation section 7. .

Next, in this embodiment, a part of the transmission area of the read image 1 shown in FIG.
The case where the image is enlarged twice and sent will be explained.

The control unit 6 transmits the area '°△II CD'' of the read image 1 shown in FIG. The control section 6 outputs this information to the sampling clock generation section 5.The sampling clock generation section 5 receives an instruction to enlarge the read image 1 twice and send it.
The clock for sampling the binary time-series image data corresponding to the area 'A B CD' in the figure is set one-to-one with the image data from the image reading unit 1. The encoder/decoder 3 inputs data according to the link clock output from the link clock generator 5. The decoding unit 3 performs band compression on the input image data and outputs it to the line control unit 4. The line control unit 4 receives the band-compressed one-to-one image data from the τ) conversion/decoding unit 3. is output to the line 100.Then, the sampling clock generator 5 outputs the signal as shown in FIG.

The clock for sampling the binary time-series image data corresponding to the area of EF is rewritten and generated in a 1:2 ratio with the sampling clock from the image reading section],
It is output to the encoding/decoding section 3. Thereafter, the band-compressed one-to-two image data is output to the line 100 through the same process as described above.

In the following explanation, an example was shown in which a part of the read image is enlarged twice and transmitted, but since the sampling clock generated by the sampling clock generator 5 can be rewritten, further enlargement at a different ratio is shown. It is possible to perform processing such as reduction in arbitrary ratios, extraction of different regions, etc. before transmission.

The same applies when receiving and recording in the image recording section 2, and for image data input from line 00 via the line control section 4 and decompressed by the encoding/decoding section 3,
By the operations of the sampling clock generating section 5, the control section 6, and the operation section 7 similar to those described above, it is possible to perform processing such as reduction or enlargement of an arbitrary ratio and extraction of an arbitrary area, and to receive and record the processing.

-゛- [Effects of the Invention] As explained above, the present invention provides a thinning/expansion sampler 17 that can be replaced with a lean printer clock every time it is generated. By providing a specified control unit, it is possible to arbitrarily reduce or enlarge the read image and the received recorded image and extract an arbitrary area without increasing R, OM or random logic. be.
