[Brief explanation of drawings]

Figures 1 to 4 show the conventional method of configuring signals, Figures 5 to 21 show examples of the present invention, and Figures 5 to 11 show how to create signals. 12 to 21 show the steps for reproducing images. 1 and 5 show the basic part of the image before conversion to a signal, the black image 5 being the same. 2 and 6 are divided into N pixels. FIG. 3 shows the state in which the information of each pixel is converted into a signal N.2. FIG. 4 shows an image 5' obtained by restoring the signal from FIG. 3. FIG. 7 shows a diagram in which information N.1 in which both white and black exist in a pixel is represented by A. Figure 8 shows the basic part 10, Figure 9 shows the child part 11, and Figure 10 shows the grandchild part 12.

Claims (1)

[Claims for Utility Model Registration] 1. A still image is composed of information N.1 representing the characteristics of each of a large number of pixels N in a two-dimensional distribution obtained by dividing an image such as an image that changes over time, and is used for communication or storage. Regarding the method of replacing the information with a signal with a one-dimensional distribution for the purpose, when the entire image or the part obtained by dividing the image into two or more parts is defined as the basic part 10,
The basic part 10 is first divided into two or more child parts 11, and the child part is further divided into two or more grandchild parts 12, and the child part is a child part 11a in which the second division is located. and a child part 11 without the second division.
b, and information 11 on the presence or absence of the second division.
1 is replaced with signals 11 and 2 having a one-dimensional distribution. 2. Configuration of a signal for reproducing the image set forth in Claim 1 of the Utility Model Registration Claim, in which the child part obtained in the first division is set as a new basic part, and the procedure is repeated two or more times using the step 3. Method. 3 Let the smallest grandchild part 1n generated by the last division in step 3 be the pixel N, and the information of the pixel N・1
A method of configuring a signal for reproducing an image according to claims 1 and 2 of the utility model registration, in which the signal N·2 is replaced with a signal N·2 having a one-dimensional distribution. 4. A method for configuring a signal for reproducing images as set forth in claims 1 to 3 of the utility model registration claims for use in image communication such as television or facsimile, or in a device for storing images containing characters. 5. The method of configuring a signal for reproducing an image according to claims 1 to 4 of the utility model registration, wherein the first division of the basic portion 10 or the second division of each child portion 1n is performed according to a certain rule. 6 Information N of all pixels included in the basic part 10
- A method of configuring a signal for reproducing an image according to claims 1 to 5 of the utility model registration, in which the portions are not divided when 1 is equal. 7. A method of configuring a signal for reproducing an image according to claims 1 to 6 of the utility model registration claim, in which the information representing the basic portion 10 is comprised only of information 1n.1 as to whether or not each portion is divided. 8. A method of configuring a signal for reproducing an image according to claims 1 to 7 of the utility model registration, in which the information 1n.1 on the presence or absence of division is a signal that is expressed in two levels such as 0 and 1. 9 The number of times step 3 of dividing the basic part 10 is performed can be arbitrarily selected.
8. Method of configuring signals for reproducing images. 10 The first division of the basic portion 10 or the second division of each child portion 1n is a method of configuring a signal for reproducing an image according to claims 1 to 9 of the utility model registration, in which the first division of the basic portion 10 or the second division of each child portion 1n is approximately bisected vertically and horizontally.
