Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a method of rotating a stored signal pattern.

[Technical background of the invention and its problems]

Generally, characters and symbols are used as a means of transmitting or displaying various types of information, but when displaying information on terminal devices such as displays and printers, these character patterns are expressed as a combination of multiple dots. It is often done. Character patterns are stored in a so-called character generator in advance at intervals of τ, and corresponding character patterns are sent to terminal devices such as displays and printers using character codes assigned to each character. Therefore, the types of characters, symbols, etc. that can be displayed are limited to character patterns stored in the character generator.

However, if the information is to be displayed as is without any processing such as analysis, statistical processing, or graphing, a character pattern oriented in one direction, such as an erect character pattern, is sufficient. However, a wide variety of information is currently being disseminated, and necessary information is often selected from it and processed through analysis, statistical processing, graphing, etc. in order to make it easier to view and understand. In such a case, not only an erect character pattern but also a horizontal or inverted character pattern, such as a character pattern in which the integer of 90 is omitted by 8 times, is required.

In such cases, it is possible to pre-memorize not only upright character patterns but also horizontal writing patterns and inverted character patterns in the horizontal direction, but the As a result, the character generator becomes large and very expensive. On the other hand, certain characters
It is conceivable to store various character patterns only for symbols, but since which characters are used in which orientation depends on the type of information, it is difficult to predict and is not practical.

Conventionally, as a character pattern generator or conversion method that made it possible to generate character patterns for both vertical and horizontal writing from character patterns stored for M (or horizontal) writing, there was No. 7102, Special Publication No. 54-3381
No. 5, Special Public BH No. 54-33816@, etc. However, these character pattern generation devices or conversion methods are only concerned with the conversion between 'b Ifl F-+ and horizontal writing which is limited to one direction. However, it was not possible to obtain the horizontal writing character pattern that is possible. Moreover, the configuration for obtaining a horizontally written character pattern from a vertically written character pattern, for example, is complicated.

[Purpose of the invention]

The present invention rotates bit patterns of characters, symbols, etc. stored in a certain orientation, for example, by an integral multiple of 90 degrees (
It provides a method of rotating the stored pattern obtained in a re-stored form.

[Summary of the invention]

When rotating the dot pattern related to the signals such as characters and figures stored in the first dot matrix storage section, all the bits constituting the foreground first dot matrix storage section are customized, 1 pixel 1. Vanguard pick 1 at the coordinates according to the desired rotation angle every ~
Convert the pattern and write it in the corresponding position of the second dot matrix storage section! - By doing so, a storage pattern rotation method is obtained in which the storage pattern can be rotated by a desired angle.

[Embodiments of the invention]

Hereinafter, an embodiment in which the method of the present invention is applied to a character generating device that outputs a single screen will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a character generator.

When character information consisting of a character code and rotation instruction information is inputted from an external device such as a computer, the control unit (1) deciphers them and also converts the characters according to the manually generated characters and rotation instruction information. It controls the bit string generation section (2), character storage section (/l), and function circuit section (3). The character bit string generation section (2) is composed of, for example, a sharp roughter generator, stores a character pattern for each character code, receives a control command from the control section (1), decomposes the character pattern into a bit string, Output to control unit 1 section (1). In this way, the character pit pattern generated from the character bit string generation section (2) is transferred to the generated character storage section (41) consisting of a dot matrix in the one-way character storage section (<4) via the control section (1). be remembered. The capacity of the generated character storage section (41) is at least b bits.times.b bits, which is the same as the size of the draft matrix constituting the character pattern generated from the character generation section (2). Function circuit section (
3), under the control of the control unit (1), the generated character storage unit (
41) coordinates are converted into dots according to rotation instruction information from an external device. The converted dot data is stored dot by dot in the output character storage section (42) consisting of dots 1 through matrix of the character storage section (i). When the conversion of all the dot matrices constituting the character specified by the character code is completed, the control section (1) outputs the contents of the output character storage section (42) to an external device.

Next, the operation effect will be specifically explained.

Here, for the sake of explanation, we will take up the rotational display of characters, symbols, figures, tables, etc. expressed by a dot matrix of b bits x b pills, where b is a natural number equal to 1'. First, Fig. 2 shows an example of an input format related to character information inputted to the control unit (1) from an external device (not shown) such as a 4-character machine. The information indicates the desired character display orientation, J rotation instruction information, and character code 1.
It consists of a time-division signal with a period. This character code is assigned to each signal pattern, such as a character pattern, such as a character, symbol, figure, etc., which is stored in advance in the character generator of the character pip 1-character generator (2). On the other hand, the rotation instruction information can be distinguished by expressing this information as P and assigning meanings to the vessels of P, respectively. That is, the P value is set in advance as follows, for example.

O = [Do not rotate the character] 1 - Rotate the U character 90 degrees clockwise - 12 - [Rotate the character 90 degrees counterclockwise around J1" (rotate 270 degrees) 3 = Rotate the F character 180 degrees clockwise It is J that rotates a degree.

Regarding the rotation instruction information for input formats 1 to 1,
After the initial settings, it is also possible to configure the settings to be omitted as long as there are no changes.

When such character information is manually input to the control unit (1), the control unit (1) outputs l! ? Reading, the character -1-do is the character occurrence part (
2), the generating unit (2) selects the corresponding character pattern, decomposes the selected character pattern into a bit string, and sends it to the generated character storage unit (1) via the control unit (1).
41).

Next, the control unit (1) supplies the rotation instruction information P and the bit pattern of the specified character as input variable data to the function circuit unit (3), and inputs the character hit pattern stored in the generated character storage unit (41). After rotating the character by a desired angle dot by dot, the bit pattern constituting the character is recorded for each bit from the generated character storage unit (41) to the output character storage unit (42) via the control unit (1). Rir. When the desired rotation of all the b-bit×b-bit dora 1 matrices is completed, the control section (1) outputs the rotated characters to the output signal line (12).

Here, the data conversion process in the function circuit section (3), that is, the process for obtaining the desired rotation, is performed as follows.

Now, an arbitrary dot area in the generated character storage section (41) is expressed as (i, j), and a dot area after rotation processing is expressed as (m, n). However, i, j, m,
All n are natural numbers that are equal to or smaller than b. Therefore, the input conditions for the function circuit section (3) are (P, i, j, b), and the output of A is (m, n
). If we adopt a coordinate system as shown in Figure 3(a) for the dot matrix that constitutes a character, the value of P has the meaning as described above, so when P-0, m=i, n-j When P=1, m = b-1-j, when n = iP=2, m = j, n = i When P=3, m = +, 11-11-1-, in the relationship of i be.

Therefore, (m, n) of the function circuit section (3)C is determined by the value of the rotation information [).

In the above manner, the character II A I+ is represented on the 7-bit x 7-bit matrix shown in FIG.
FIGS. 3(b) to 3(1) show the results of rotation by integer multiples of 90 degrees.

In the above embodiment, the coordinate system for the dots 1 to 1 of the characters is adopted as shown in FIG. 3, but the coordinate system is not limited to this. 4r+L, , in which case (i, j) for the value of P (m, n
) changes, but the difference is which dot is taken as the origin of the coordinate system.

In addition, in the second embodiment, the number of dots in the dot matrix constituting the characters is the same in the rows and columns, but it does not necessarily have to be the same, and the number of rows and columns may be changed or changed sequentially. The entire structure may be rectangular or circular.

Furthermore, in the above embodiment), the input signal input to the control section is
Although we have described an example in which the matte signal is input from an external device such as a rotary machine, it is beyond the scope of this description to explain that the desired rotation can be made not only from the external device but also from any signal pattern stored in the device itself.

Furthermore, in the above embodiment, the rotation of the character code from the calculation mode was explained, but the rotation of the character code in the generated character storage section
This invention can be applied if the input is image information from a television camera or fax, or a signal stored in the form of a bit pattern in a dot matrix.

〔Effect of the invention〕

According to the present invention, it is possible to obtain a re-stored pattern by rotating the bit pattern stored in the dot matrix storage unit by an arbitrary angle, for example, an integer multiple of 90 degrees, and the display format of various information is g: 1 become rich.

Further, in the above embodiment, there is no particular restriction on the size of the dot matrix of the character pattern that can be handled by the character generator, and even special symbols or symbols can be used, providing very high versatility.
