The present invention relates to an image system using vector pixels in a computer program. More specifically, the present invention relates to an image system using vector pixels. More specifically, the computer program includes one unit of data, i.e., top, bottom, left, right, top, left, bottom, The present invention relates to a system that includes direction information of any one of the right and bottom vectors to draw, enlarge, reduce, rotate, transform, and write, read, and store the data on a computer.

There are two types of expression units used in computer programs, namely, image representation units, coordinates for drawing, and pixels for displaying bitmaps. . Coordinates usually take 4 bytes (2 bytes of X coordinates, 2 bytes of Y coordinates) to display one point by digitizing the position of the horizontal (X) axis and the vertical (Y) axis, and the pixels are the three primary colors of red, green, and blue. Each byte is assigned one byte to display one color in three bytes.

Therefore, to display the location information and color information of a point independently at the same time takes 7 bytes per point, which takes up a lot of memory, so it is not used well unless it is extremely necessary. For this reason, the display of image information generally uses a method of arranging pixels of 3 byte size in order in a horizontal and vertical quadrangular shape.

Currently used image file formats are GIF, JPG, and BMP file formats. These image files have the following differences.

Most of the pictures that can be viewed on the Web site are JPEG (JPG) and GIF files. These two files are popular graphics because of their amazing compression ratios and other advantages, with the simple difference being that they use JPEG for photos and pictures with a lot of colors, and GIF for the rest.

GIF (Graphics Interchange Format) files are widely used for homepage icons because of their small capacity when storing pictures in 256 colors. All the moving pictures on the Internet are gif files.

Joint Photographic Experts Group (JPEG) files have a very high compression rate when storing photos or pictures with a large number of colors, which can dramatically reduce the picture size.

BMP (Bitmap) files are uncompressed files, which are very large in size, so they appear on the Internet screen very slowly, so they usually use a lot of compressed files.

Compression has a lossy compression method and a non-lossy compression method. The basic principle of compression in an image file is to reduce it with its own rules for repeated colors (content).

In the case of JPG, the lossy compression method is used. JPG can express 16 bits, 24 bits, or 16,777,216 colors. Repeatedly reducing the number of colors in the compression process damages the image is called a lossy compression method. However, due to the many colors that can be expressed, it is suitable for expressing photorealistic images such as photographs and has a high compression ratio.

For GIF, use the lossless compression method. In other words, if you use the GIF file format, it can be compressed without damaging the original image. However, since GIF uses only 8 bits for color information, it can only display 256 colors. As a result, images such as photographs are removed from the 256 colors that can be expressed by storing them in the GIF file format. Therefore, GIF is good for expressing pictures drawn directly.

Since JPG and GIF, the best of both worlds is the PNG format. JPG's high quality and GIF's transparency, lossless compression, plus bonus metadata (additional information, e.g. layer information), but unfortunately it doesn't support animation and is not yet supported by web browsers. .

Drawing information in a drawing program (CAD, Computer Aided Drawing) such as Auto CAD, which is widely known around the world, is a midpoint due to 4-byte information indicating coordinates or due to quantitative burden (memory size, disk storage capacity, communication speed, etc.). Omit all of them, and keep only the essential points such as the starting point and end point of the straight line, or the center point of the circle or the reference point of the curve, and then connect them with a straight line, an arc, or a Bezier curve. use. In addition, CAD software reduces the amount of data by minimizing color representation.

On the other hand, the information storage system of image files represented by Bitmap of Microsoft's Windows follows a method of sequentially arranging three bytes of color information inside a predetermined square. Therefore, it is impossible to omit the meaningless background part of a single color, which leads to the disadvantage that the file becomes large. To solve this problem, various file compression methods have been developed. According to this compression method, various formats such as JPG, GIF, TIF, PNG appeared. However, even if the compression does not escape the frame of the quadrilateral, it is difficult to respond when it is necessary to express an arbitrary shape. To compensate for this, a method of transparently processing a specific color (GIF method) and another simple image for a mask (Bitmap) are used.

In the case of such a general image file and conventional image processing, the need for more compressed and faster processing for video, 3D graphics, and various types of fonts in games, mobile computing, animation, etc., which are future computer applications. As a result, the technology for minimizing the size of data while simultaneously expressing direction information and color information is urgently needed.

SUMMARY OF THE INVENTION The present invention has been made to overcome the problems of the above technique, and it is not a technique of compressing data as in the conventional image data display forms (BMP, JPG, TIF, GIF, etc.), but rather the amount of data by changing the representation method of image data The main objective is to present a system that creates and executes a new file structure that radically reduces the amount of work to produce an image.

Another object of the present invention is to easily replace, synthesize, and copy vectors using a variety of string handling functions so that a general CAD program does not have to transform all shapes after drawing, but has to constrain all complicated calculations before drawing. The drawback of the method is to supplement the figure already drawn by expanding and contracting in an arbitrary direction.

Another object of the present invention is that the color information of an image file having a structure that lists color information generally includes all numbers including 0 in the color information, so it is difficult to include a separate control character, such as TIF or PNG. Declaration of the length of data that follows is used, but the method is used.However, it is not superior to the complicatedness of the method. It is to provide a configuration that can be done.

Another object of the present invention is to apply the Brezenam line / circle drawing method and the Bezier curve method to freely draw a variety of lines, figures and to propose an optimal deformation, substitution method.

It is a further object of the present invention to construct a structure that can easily implement a three-dimensional image according to the characteristic that the three-dimensional information can be moved and changed by putting the three-dimensional information in the file structure and the characteristic that can express three-dimensional coordinates with a simple data structure. To provide.

In order to achieve the above object, the image processing system using a vector pixel according to the present invention, any one of eight vectors for the up, down, left, right, top, right, left, bottom, right direction along the X, Y axis A vector pixel (10) consisting of a vector information unit (11) storing the vector information of the data in the lower four bits of one byte; A data unit structure (110) having a landmark viewer (111), which combines the vector pixels (10) to form a partial image and means a boundary of the partial image; A data unit (100) having a terminator (101) which means that the data unit structure (110) is combined to form an entire image but is terminated at the end; A file generation unit 300 constituting the data unit 100 according to a specific command and generating and storing a computer image file based on the data unit 100; And a data processor 400 for implementing an image by processing a direction indication according to the vector information of the image file generated by the file generator 300.

In addition, in one byte of the vector pixel 10, two bits of the upper four bits in front of the vector information unit 11 store vector information about the front and rear directions along the Z axis.

      In addition, in order to assist the function of the vector pixel 10, any one of coordinate values, additional vector information, and color information is included in the form of a control command so that the vector pixel 10 and the vector pixel 10 may be separated from the data unit structure 110. A control unit (20) consisting of a control character (21) containing control command information and control parameters (22) required for command processing for the control character (21); It is characterized by including.

In addition, in order to declare the function of the data unit 100 to assist or command processing, any one of a starting point, a coordinate value, additional vector information, and color information is included in a command format in front of the data unit 100. Header 200; characterized in that further comprising.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following description is an example for explaining the basic idea of the present invention, and the spirit of the present invention is not necessarily limited to the above embodiments, but may be extended to applications in a similar category.

1. General description of image processing according to the present invention

1 is a block diagram showing a schematic configuration of an image processing system using a vector pixel according to the present invention.

As can be seen from FIG. 1, the system according to the present invention is preferably executable on a computer, and the basic data structures and relationships constituting the system will be described first.

The most basic data structure of the present invention is a basic vector pixel in which vector information of one of eight vectors for up, down, left, right, top left, top right, bottom left and bottom right is stored in the lower four bits of one byte. 10a) or a vector pixel 10 having the basic vector minimum unit as an extended vector pixel 10b obtained by adding 3 bytes of color information to the basic vector pixel 10a.

The data unit structure 110, which is a structure for image representation, is formed by sequentially arranging / combining the vector pixels 10 including the basic type / expanded vector pixels 10a and 10b having the direction information that can be expressed as such eight kinds. And the data unit structure 110 is also combined to generate information and commands of the file generator 300 and the file generator 300 for generating and storing the data unit 100 expressing the overall image according to a specific command. Having a data processing unit 400 to implement an image through is the basis of the system according to the present invention.

In addition, the data unit structure 110 is combined with the vector pixel 10, the control unit 20 containing a certain control information, the control character 21 in the upper 1 byte and the control character 21 in the lower minimum 3 bytes. The control parameter 22, which is data necessary for the execution of the command, has a structure of a total of at least 4 bytes, such that the control unit 20 can assist the vector pixel 10 and the control unit 20 according to the present invention As an auxiliary unit of the system.

That is, the data unit structure 110 divided by the landmark viewer 111 having a constant value is formed by combining the above-described vector pixel 10, which is the basic unit, and the control unit 20, which is the auxiliary unit, and the file generation unit 300. One or more of the data unit structures 110 are gathered together to form a data unit 100.

The system according to the present invention can optionally include a header 200 optionally in front of the data portion 100 to provide a basis for executing instructions that are declarative or basic premise as a beginning.

The system according to the present invention having such a basic configuration includes a vector of up, down, left, right, top left, top right, bottom left and bottom right in a computer program, including a figure of a figure and image data in image processing. , Reduction, rotation, and transformation, and simultaneously present a method of writing, reading, and storing data configured as described above on a computer.

As mentioned above, however, again, the basic unit of data referred to herein is a vector information string 11 or a string format of a vector alone or a vector expressed in hexadecimal (hereinafter referred to as "0x1" to "0xf"). Extended vector pixel having a total size of 4 bytes consisting of a color type information unit 13 including 3 bytes of color information included in the basic vector pixel 10a having the auxiliary vector information unit 12 and the basic vector pixel 10a. It is a vector pixel 10 (hereinafter also referred to as "VEXEL") which has any one of (10b) as a basic unit.

In particular, the vector pixel 10 having a unit of 1 byte stores one of eight pieces of vector information in the vector information unit 11 positioned at the lower four bits, and in the auxiliary vector information unit 12 corresponding to the upper four bits. Stores separate independent vectors or includes additional vectors corresponding to one of three dimensions (specifically, information about the direction before and after the Z-axis), and optionally, the vector pixel 10 is stored in one or more consecutive data. The control unit 20 including the control command is added to perform various functions.

The set of basic vector pixels 10a among the vector pixels representing the direction information is a sequence of one-byte data, that is, the same form as a String, so that a string processing function (that is, C) is performed directly by a register of the computer CPU. strcpy, strcat, strlen, etc.), and also makes it possible to handle components of a figure already drawn by the vector pixel 10 one by one. I can convert it.

Generally, an image file is a structure that lists color information. It is difficult to include a separate control character because all the numbers including 0 are included in the color information. One way to overcome this is to declare the length of the data following from the beginning, such as TIF or PNG, which is not useful because of its complexity. The image file according to the vector pixel 10 according to the present invention follows a special way of overcoming this without declaring a data length that follows.

Since the basic skeleton of the vector pixel 10 contains only the direction information in a state without including a coordinate value, it is recognized as a completely new concept from the method of drawing due to the existing vector. Since the color information based on other known image files is added in the present invention if necessary, the basis thereof is different. Therefore, an image file (hereinafter, also referred to as a "GRIM" file) generated by combining the continuous vector pixel structure 10 (combination unit is added with data unit structure and data) is not an image file in a strict sense. However, you can't put it in a category of CAD files that contain 'location' information, not direction. This is because, unlike a CAD file having only a reference point, the system according to the present invention has all the direction information of all points to be represented in each successive vector pixel 10 for image realization.

For this reason, the existing CAD file can not be read without the help of a function for drawing a straight line or a function for drawing a circle, that is, an intermediate drawing function, but the GRIM file according to the present invention does not need the help of an intermediate drawing function. Windows Metafile Format (WMF) files supported by Windows also require Windows' built-in drawing functions.

In other words, the concept of a vector introduced in the present invention is a unit vector having only a 'direction' which does not include position information and data in a continuous string format thereof. In this respect, it is fundamentally different from the concept of "vector graphics" or "vector font" known so far. They are all based on digitized 'coordinate' data. That is, the vector does not mean the original vector because it means that the coordinate value without the direction indication is read and interpreted in order. However, the vector of the present invention is a vector of mathematically perfect meaning.

1.1 set of unit vectors

(1) The basic data constituting the system according to the present invention is a contiguous set of unit vectors, that is, vector pixels 10. The size of the unit vector is 1 by default, but you can change it anyway. For example, if the size of the unit vector is set to 0.1 and all the processing is performed, then extracted 10 times, that is, the unit of 1, a fine and high quality image can be obtained. Changing the size of the vector is an application utilizing the system according to the present invention, specifically, a 'size change module' for changing the numerical value of the size of each vector pixel (unit vector) information is added in the data processor 400. It can be realized by including

(2) When applied to the field of machine tool, if the unit is set to micron or 0.1mm according to the required precision, the same result can be expected without any change.

Pixel with 1.2 direction

(1) Existing drawing or image data are numerical coordinates only, and there is no moving direction. The vector pixel 10 having only a direction according to the present invention exhibits various specificities. Continue to take the point to the right or left of the moving direction to give a certain thickness for any curve (as described later by the 'ply-figure' structure), and to easily plot internal and external points for any closed curve. It can be determined.

(2) Because it has a direction, of course it has a 'order'. Graphic processing data having a known coordinate value has the same result even if several points are displayed regardless of the order, but the vector pixel 10 according to the present invention shows different results. In addition, since the unit displacement (base amount: 1) is added in sequence, changing the direction of one point changes the positions of all following points. This feature enables editing of shapes, compositing two data unit structures 110, and creating associated pictures such as symmetric shapes.

1.3 principle of omission

In principle, in the image processing system using the vector pixel according to the present invention, data that is not necessary is omitted. The image data of the conventional processing method is contrasted with that which cannot be omitted even if it is filled with 0 when it is not necessary in a predetermined frame.

Specifically, this is the case with the header 200 optionally included, and whether or not, for example, fills the meaningless background of the quadrilateral image with the same color through a command of the control unit 20 or the like. The above-mentioned examples are possible characteristics because the control unit 20 may be included in the data unit structure 110 as mentioned above and a pixel having a direction may contain a position.

2. Basic structure of data and file according to the present invention

2.1 data structure

Pixels (one point of the screen) introduced in the present invention, that is, data such as a vector pixel 10 (hereinafter referred to as "Vexel") and an accompanying control unit 20, a data unit structure 110 formed by combining them, Furthermore, the structure or configuration of the data unit 100 is shown in FIG. 1, and such a configuration may be classified according to the structure of the byte as follows.

(1) A structure that can be made within the range of 1 byte

a. Basic vector pixel 10a stores one of eight vectors of up, down, left, right, top left, top right, bottom left and bottom right in the lower four bits of one byte, that is, vector information unit 11. The meaning of the upper 4 bits, i.e., the value contained in the auxiliary vector information section, is described below) (see FIG. 1 (a)).

b. Landmark indicator 111: Indicate a boundary between each data unit structure (10) representing a partial image in a state having a constant value (preferably hexadecimal ff) or distinguishes infinite length data to be described later. (e) to (f))

c. Terminator 101: Has a certain value indicating the end of the data portion 100 representing the entire image, indicating the end of the entire image (see Fig. 1 (f)).

d. Three-dimensional vector information: means that the front and back vectors (for example, Z-axis-related directions) that can be composed of two bits in addition to the eight basic vectors included in the vector information unit 11 are stored in the auxiliary vector information unit 12. (See FIG. 1 (b))

e. Layered picture vector information: This means that the vector information contained in the vector information section 11 has the same four bits as the same information in the upper four bits of the basic vector pixel 10a, that is, the auxiliary vector information section 12 (see Fig. 1 (b)). )

(2) 4-byte structure

a. Extended vector pixel 10b: A structure including a three-byte color information unit 13 connected behind a basic vector pixel 10a in units of one byte, and R (Red) and G (Green) in this three-byte color information unit 13 ), B (Blue) has three primary color information.

b. Control unit 20: control character 21 in the first to second, preferably the first one byte within at least 4 bytes of space, followed by at least 3 bytes (if the control character corresponds to 2 bytes Has a size of at least 2 bytes) and consists of at least 4 bytes of control parameters 22 necessary for executing the command of the control character 21, and is not a pixel for displaying one point, but the vector pixel 10 and the vector pixel. Parallel / combination forms the data unit structure 110. That is, the control unit 20 composed of 4 bytes may display additional vector information and color information, and generate and execute other necessary commands to assist the function of the vector pixel 10 composed only of direction information. . This will be described in more detail with reference to FIG. 3.

(3) infinitely long data structures

a. Unstructured data: Non-pixel data (usually textual information) that begins with a delimiter and ends with a delimiter.

b. Data unit structure 110: performs a function of implementing a partial image, ending with the landmark viewer 111 may include the vector pixel 10 to the control unit 20 or the atypical data (FIG. 1). (e) see)

c. Data unit 100: to perform the function of implementing the entire image, the terminator 101 ends in the combination of the data unit structure 110 and the header 200 to be described later can be located in front. f))

2.2 Header Structure

(1) basic

1 byte of control, 1 byte of type, 2 bytes of ID, 4 bytes of mode, 4 bytes of Pini (coordinate of starting point), 4 bytes of color; It consists of 16 bytes in total and details are shown in FIG.

(2) extended

In addition to the basic type, it has a 8-byte post and 12-byte name at the same time, and details are shown in FIG.

2.3 Image File Structure

It is shown in FIG. 1 (g) and consists of a header 200 and a data part 100. The header 200 may be omitted according to a condition.

2.4 Structure of the Entire System for the Invention

As shown in FIG. 1G, the file generator 300 and the header 200 to the data unit for generating an image file including the header 200 and the data unit 100 according to a specific command or necessary combination meaning. It is composed of a data processing unit 400 for processing and controlling commands to the control unit 20 in the 100 to ultimately output and implement an image on a monitor.

3. Structural characteristics of the data constituting the system according to the present invention

3.1 Characteristic of Basic Vector Pixel 10a and Data Structure

(1) It does not have numerical coordinate information other than direction information.

Since the existing CAD files, font files, and the like corresponding to the basic vector pixels 10a all have digitized coordinate information as basic data, the vector pixels 10 according to the present invention can be regarded as outstanding characteristics that can be compared thereto. have. There is no known graphic processing method that does not store numerical coordinates as data regardless of general or vector graphics.

(2) Keep all positional information (vector format) of all construction points to be displayed.

In general, the configuration data of a drawing for a computer is stored only for representative positions such as a start point, an end point, and a center point because of the simplicity of the information and the excessive memory burden. In the vector pixel according to, all of them can be displayed at once.

That is, since the positions of one point can be represented by a vector of 1/2 to 1 byte, there is an important advantage such that the memory burden is small, and the information of all the corresponding points can be edited to edit them.

(3) A landmark indicator 111 for specifying the end of the data unit structure 110 is defined.

Existing drawings or image data contain all numeric values, including zero, so that no special purpose text or information can be included separately. However, the vector pixel 10 according to the present invention is provided in units of 1 basic byte, and uses only 8 types of direction indications among the values that can be expressed from 4 bits to 16 types, and manages various special roles with the remaining 4 bits. Of course, the landmark indicator 111 may be located at the end of the data unit structure 110 in a separate byte space, but optionally 4 bits of space can sufficiently achieve the purpose. For example, the vector pixel 10 may be positioned in place of the auxiliary vector information unit 12 in a space of the upper four bits corresponding to the auxiliary vector information unit 12.

(4) It has a terminator 101 for marking the end of the data portion 100.

As the terminator 101 which marks the end of the data part 100, it has a compulsory zero. This is because it is compatible with the string data of the C programming language and provides many advantages.

(5) It further includes a control unit 20.

The control unit 20 is for supplementing / defining the function of the vector pixel 10 having only the direction information, which is the basis for executing various commands, which will be described separately.

3.2 Characteristics of the Expandable Vector Pixel 10b

(1) The color vector is combined with the basic vector pixel 10a.

All characteristics of the basic vector pixel 10a are inherited as it is, and color information may be omitted according to the setting of the header 200 or the control unit 20 when the same as the previous pixel.

(2) It is not a fixed square or fixed shape.

All existing image files have a format of sequentially arranging color information for a fixed horizontal and vertical sized square. However, in the vector pixel 10 according to the present invention, since the position is defined by the vector information unit 11, it may have any shape. That is, the transparent portion or the background portion having the same color may be omitted.

(3) A well-known header for specifying the size is unnecessary.

As a matter of course according to the above (2), almost all existing image files inevitably have a header even in order to specify only the size of the image, but it is not necessary in the extended vector pixel 10b according to the present invention. That is, the header 200 may also be included in the present invention, but at this time, the header 200 of the present invention may have a meaning as an optional configuration rather than an essential configuration.

3.3 Characteristics of the control unit 20

Since the vector pixel 10 can only represent relative positions between adjacent points of successive pixels, it is necessary to provide a special configuration to display discontinuities or to add additional vector information, color information, and other functions. In response to this purpose, it is the role of the control unit 20 to express, in command form, information and other functions that mainly specify the position of the pixel to be currently displayed. Of course, in addition to positioning, as shown in FIG.

The control unit 20 has a constant length of at least 4 bytes in most cases, but there is a special case having an infinite length.

(1) Configuration of Control Unit 20

 As shown in (d) of FIG. 1, the control unit 20 is composed of at least 4 bytes, wherein the control character 21 of 1 to 2 bytes and at least 2 bytes (in which 2 bytes, the control character is 2 bytes). The control parameter 22 which is applicable when it is made and is basically attached data of 3 bytes) is comprised.

(2) control character (21)

The upper 4 bits are filled with the control indicator 21a of a certain value (default value: '15', hexadecimal 'f' value) that declares or indicates the control character 20, that is, the control character. The 4 bits consist of a control identifier (0 to f in hexadecimal) 21b for identifying the type of control (see Fig. 3A).

This ensures 16 control characters 21 between hexadecimal (denoted with the prefix "0x") f0-ff. The role that these 16 control characters 21 can play is illustrated in FIG. They can be changed at any time in the implementation of the system according to the invention.

(3) control parameters (22)

The control parameter 22 except for the control character 21 of the control unit 20 is a parameter required for command processing of the control character 21 and can be divided into two cases according to the degree of byte provision. Of course, at this time, the control character 21 is also divided into two according to each, which is well shown in Figures 3a, b.

The first case is mainly for instructions that require more than 3 bytes of space such as color information, X, Y coordinates, etc. (in the example of FIG. 3, 0xf1 to 0xfe), and the second case can be executed with about 2 bytes of space. The command has an additional control character 21 in the first byte of the control parameter 22 (second byte of the control part) (corresponding to 0x10 to 0x40 in the example of FIG. 3B).

In particular, according to the second case, the control byte of 4 bits in the first byte is obtained because the control byte of 2 bytes is secured by the additional control character 21 from the limitation that only the 16 controls can be handled by the first byte. 16 kinds that can appear in 4 bits except indicator 21a and 16 kinds that can appear in 2nd byte (in theory, 256 kinds can be represented in 2nd byte, but at least 16 kinds of information can be represented) (Assuming that byte space is utilized), it is possible to process more than 255 instructions of '16 * 16-1 '.

(4) infinite length control

As a place name on the map, a control provided for insertion of data that is difficult to process at a constant length, and is divided into a leading start and end of a constant control character 21 (default value 0xff).

The first character after the beginning 0xff may be an additional control character (21) that specifies the type of control or may be omitted. If omitted, it basically means the data unit structure 110, but this basic can also be changed in the mode of the header. Additional controls allow the font type, size, and color of the string, but are not specifically illustrated.

When the terminator 101 follows immediately after the landmark indicator 111, the landmark indicator 111 may be omitted.

3.4 Header Characteristics

(1) the position of the starting point, the meaning of the auxiliary vector information unit 12 of the vector pixel 10, etc., for the information specified in FIG. 1 (a), having a basic header, and corresponding to the ID of the data unit structure 110; If information is needed, it may have an extended header.

However, for simple one or two pieces of information, the header may be omitted, and the data unit 100 may immediately start with the control unit 20. Many of the descriptions in FIG. 3 (except for meaning that does not make sense at the beginning, such as the RETURN command) may be at the beginning of the image file. Regardless of the presence or absence of the header 200, while the image display progress pointer is in the position before deviating from the first point, it is defined as being at the beginning.

(3) Therefore, if the beginning provision of (2) above is used well, it is possible to obtain an effect of selecting and using more types of headers rather than two types of headers.

(4) Characteristics by Configuration Factors

Pini displays the coordinates of the starting point, which may be omitted, but is received when another data unit structure 110 is called with respect to the data unit structure 110 described later, or several data unit structures 110 are connected. This is necessary to indicate the relative position when forming a large image.

color represents the color at the current position. It implements the overlapping color omission technique, the most common technique of compressing image files. It is necessary to mark only the vector without omitting the case where the color of the next pixel is the same as color . Although not listed here, adding one more Hcolor item allows you to specify the color of the overlay picture described in How to Create a Layer Picture, below, and increases the probability of omitting the color information and displaying the next point with only the vector. As a result of the rough statistics, the color alone can reduce the file size by about 1/3, and the two standard colors can be reduced by almost 1/2. Instead, it takes time to compare whether the target color is the same color, so it can be adopted for large pictures or when the size of the file is more important than speed.

post holds the address of the calling caller and indicates where to return on return.

name allows an image file name to be displayed when a specific data unit structure 110 exists in another image file, and an identifier as a string if the user needs to specify a name that is easy to remember.

control indicates the type of file. The presence or absence of the header 200 and the type thereof are shown, and a method of adding color data is shown. The basic of adding color data is to write one of 0xf3, 0xf4, and 0xf5 instead of a vector and write color information as shown in FIG. If there is color information, it is a case of a continuous image, so the coordinates do not move in various ways, so it is possible to fill an arbitrary shape with only three directions. However, in case of requiring various vector directions, a method of adding color is separately prepared. For example, setting control at the beginning of the file to 0xf2 reads all data in 4-byte units rather than bytes. So you can read all 8 vectors instead of 3, but you can't skip color information instead. All adjacent same colors should be repeated.

type represents a more detailed kind of picture. Whether the control character 21 is present, the upper 4 bits of the vector pixel 10 serve as a separate vector, and if so, whether they are separate from the lower vector of the vector information section 11 or not (summed by default, if independent Whether there is a color for the parent vector, if there is string data, if it displays a three-dimensional position, and so on.

mode is mainly for displaying the current setting status. Of particular note is the inclusion of several picture call switches. The purpose is to manage the fact that some parts may or may not be called depending on the On or Off state of the switch. It also indicates whether name is set, post is set, etc. However, it is not relevant to non-programmers.

4. A further explanation of the system according to the invention

4.1 Auxiliary Vector Information Section (12)

The characteristics of the auxiliary vector information unit 12, which is the upper four bits of the basic vector pixel 10a in units of one byte, are summarized as follows.

(1) 0x0

This means that there is no additional vector information in the basic vector pixel 10a, and whether there is color information later depends on the level of the header 20 or the data processor 400.

(2) 0x3 or less

Indicates that this is a three-dimensional vector. That is, when the above-described eight direction information is a planar two-dimensional representation, when this value is included, the basic vector pixel 10a eventually displays a three-dimensional vector with the forward and backward direction information corresponding to the Z axis.

If it is sensitive to the processing speed, it can be overcome by defining the type described in FIG. 2, but the default processing of the vector pixel 10 is recognized as three-dimensional data. In the case of 0, that is, if there is no before and after components in the 3D vector, the same as in (1), but it is not a problem considering that the case where one of the 3D dimensions is 0 is 2D.

(3) other values:

It is a separate vector. This can be represented within 4 bits. This is a case where two points are displayed in a layered picture or one byte expressed in a manner of having the same vector information as the vector information unit 11. Of course, it is preferable to set this setting to the header 200 or the control unit 20 in advance.

4.2 Pointer Movement Function

Since the vector pixel 10 according to the present invention has vector information for each unit and the data unit structure 110 may further include a control unit 20 having various commands, the specification becomes complicated. This occurs. This sorting of complex specifications can cause problems in the speed of reading a picture, so we have several kinds of functions to move to the next pixel and manage the specifications for selecting those types separately. The implementation is the second byte type of the header.

5. Implementation of Bresenham's Line Drawing Algorithm

4 is a graph illustrating a Bregenin line drawing method.

An algorithm, published in 1965 by JE Bresenham (IBM System Journal 4 (1) 1965, pp. 25-30), that sets a set of pixels closest to a straight line between two given pixels in (x, y) coordinates. While outputting, the corresponding pixel on the screen is set as shown in FIG. 5. The mathematical principle is simple. Whenever the value of X increases by dx (1 in coordinates), the value of Y increases by dy. It is characterized by the addition and subtraction of multiplication and division necessary for proportional calculation. Multiplication keeps adding and division keeps subtracting.

In the system according to the present invention, instead of the coordinates, the position of the next point with respect to the current point is 4 bits, that is, upper (x'1000 '), lower (x'0100'), left (x'0010 '). Data by outputting 8 unit vectors such as top (x'0001 ') top left (x'1010'), top right (x'1001 '), bottom left (x'0110'), bottom right (x'0101 ') Implemented by storing in a storage space, that is, a buffer. It starts with the same principle, but there are differences in the contents as follows.

(1) The vector output straight string only hides the offset to the ending point without the starting point and the ending point. When a straight line is drawn from the starting point (x1, y1) to the arrival point (x2, y2) of FIG. 5, if x1 and y1 are different even though dx and dy are unchanged, the content outputted by the coordinates is different at that time, but the content outputted by the vector is the same. It means. In other words, straight lines with the same slope and the same length are the same regardless of the position of the starting point. This is a natural consequence of the nature of the vector. Therefore, as far as the contents of the output string are output, the same result is obtained even if all the straight lines are offset from the origin regardless of the actual coordinates.

(2) The length of the string corresponds to the larger of the vertical and horizontal components of the offset. This is because as you progress from the starting point to the arrival point, X prints one character (coordinate of one point), whether X increases or decreases, or both sides change simultaneously. This property plays a significant role in future logic development and programs.

(3) Practical straight line drawing program, like Bregenin's line drawing circle, finds the bigger component among vertical and horizontal components and sets the basic direction to one of the top, bottom, left, and right, without having to measure the X increase or decrease for each point. First, make a string corresponding to the size, and then determine an auxiliary component and its size that are orthogonal to the size, and perform an evenly distributed OR operation.

For example, if you draw a straight line from the starting point (0, 0) to the arrival point (3, 10), the default direction is `` lower (↓) '' because the Y offset 10 is larger than the X offset 3 The component becomes "right (→)" corresponding to X offset 3. Therefore, the basic character string becomes "ha ha ha ha ha ha ha ha" with 10 repeated "ha (↓)", of which three auxiliary "vectors" are added to the three "ha (↓)" and "uha (↘)". It means you make it. The end result is a "ha, ha, the lower right, lower, lower, lower right, lower, lower, lower right, and".

6. Implementing Bresenham's Circle Drawing Algorithm

In the same way as drawing a line, the method of drawing the coordinates where the next point is located from one point on the circumference or the point to be noted is calculated by calculating only 1/8 of the circle and the other 7/8 circle centered on the X and Y axes. The solution is to find the point of symmetry. In other words, the upper limit of one point (x, y) of one upper limit is (-x, y), the upper limit of three is (-x, -y), and the upper limit of four is (x, -y). (This description is irrelevant to the upper limit arrangement order of FIG. 6). The remaining four points are symmetry points with respect to the straight line y = x or y = −x of each upper limit corresponding point. The symmetry point of the (x, y) point with respect to the y = x straight line is (y, x).

5 is a circle graph for illustrating a method of implementing a circle drawing algorithm according to the present invention.

In the present invention, as shown in FIG. 5, a 1/8 circle is drawn by changing the coordinate output to the vector output as in the case of the straight line. But you cannot draw symmetry points in the same way. This is because of the difference between vectors with simple coordinates and directions. Therefore, if one 1/8 circle is divided into eight quadrants (as shown in Fig. 5), the four partial planes divided by the Cartesian coordinate axis are divided into eight linear planes that are inclined at 45 degrees. This method requires an algorithm that starts from the positive x-axis and converts it into the corresponding arc of 1 upper limit, 2 upper limits, ... 8 upper limits, etc. in the positive y-axis direction.

In FIG. 5, four points close to the X-axis are illustrated for one upper limit and eight upper limits. The content of the vector is 1 upper limit [lower, lower, lower left, lower] and 8 upper limit [lower, lower, lower, lower]. Therefore, it is easy to see that the eight-quadrant vector is reversed after changing only the value of [left] to [right] in the first quadrant vector. Similarly, the conversion rule for the remaining six eight-minute upper bounds is as follows.

Upper limit 1: default

Upper limit 2: lower-> left, left-> lower

Upper limit 3: lower-> left, left-> upper

4: Upper limit: Lower-> Upper

5 Upper limit: Lower-> Upper, Left-> Right

6 Upper Limit: Lower-> Right, Left-> Upper

7 Upper Limit: Lower-> Right, Left-> Lower

8 upper limit: Left-> Right

Even Upper Limit: Flip Order

This transformation can be used to rotate any figure or image by 45 degrees with a few modifications.

7. Implementation of Spiral Drawing Method

6 is a conceptual diagram illustrating the principle of constructing a free curve represented using a system according to the present invention.

The construction of the free curve in the present invention is implemented in two ways as shown in FIG. One is to implement a well-known Bezier curve in a vector manner, and the other is a unique method of the vector pixel method.

(A) Implementation of Bezier curve

The Bezier curve was first conceived by P. Bezier, who worked for the French Renault car company in the late 1960s. The drawing method is shown in Fig. 6A.

In the figure, M0 is the center of P1P2 and M2 is the center of P2P3. M3 and M4 are the centers of M0M1 and M1M2, and M5 is the center of M3M4. The Bezier curve defined by P0P1P2P3 can then be divided into two, a curve consisting of P0M0M3M4 and a curve consisting of M5M4M2M3. Now find the midpoints in the same way for P0M0M3M4, the left side curve, divide the divided curves into two again and continue dividing the curves in this way. Instead, draw a straight line between P0 and P3 to get the desired curve.

In the system according to the present invention, the final straight line connection is implemented as a vector string.

However, there is a method of marking the mark using the upper 4 bits of the vector byte as a buffer and proceeding the above process using the mark as a reference point. The process is as follows.

When first creating a vector string of P0P1P2P3, place a vertex mark (any number) on the upper bits of the corresponding point of P1 and P2. Then, the midpoint M0 of P1P2 becomes the string bipartite point (N / 2th character if the length of the string is N) between the corresponding vectors of P1 and P2 according to the straight string property (2), and the higher bit of this character (M0). Mark the emphasis. Similarly, midpoint display can also be performed for P0P1 and P2P3. Then, by finding the marked marks (vertexes and midpoints) and performing a straight line connection as described above, a string corresponding to each step can be obtained.

There are two advantages to this approach. One is to estimate the number of midpoints in advance in the case of Bezier curve construction prototypes and to prepare a memory space to store them. In this method, there is no need to do so, and in the case of prototypes, the curve division order (次數) should be decided here, but it is not necessary here. Because the distance between the vertex and the vertex reaches a predetermined minimum, it is possible to end the iterative operation, and it is not necessary to keep the coordinates of the midpoints that increase as the order increases. This eliminates the difference in curve quality between large and small curves.

(B) the implementation of free curves of other methods

 6 (B) shows a method of drawing a free curve differently from the Bezier curve. For triangular ABCs, AB sides are divided into n and BC sides are divided into n to connect each equal point in sequence to obtain a curve similar to a Bezier curve. Since we pass the midpoint of each side, we can geometrically prove that it is the same type of spline curve as the Bezier curve described above. This is because the midpoint is the n / 2th point and the midpoint of the lines connecting them.

If you draw a straight line from nth point to nth point of BC side and then change direction at the point where it meets n + 1th straight line, you get a vector string. This can be realized because of the linear drawing method of the system using the vector pixel according to the present invention having the above flexibility.

8. Deformation (zoom in, zoom out, rotation) of curves and images

7 is a conceptual diagram illustrating the principle of deformation of a figure expressed using the system according to the present invention.

As shown in FIG. 7, it is mathematically complicated and difficult to obtain the curve AC by modifying the wavy curve AB. This is because the size is enlarged to AB: AC and rotates clockwise by the angle ∠ BAC. However, in the concept of a vector-if the curve AB consists of vector pixels, the sum of the upper, lower, left, and right unit vectors in it coincides with the sum of the unit vectors of the straight line AB. The same applies to curve AC and straight line AC. Thus, the difference between the sum of the vectors of curves AB and AC is equal to the difference between the sum of vectors of straight lines AB and AC.

Therefore, a straight line character string connecting two points B and C is distributed and properly distributed in the curve AB to obtain the curve AC. In this case, "distribute appropriately" means that the length of the character string can be divided into equal parts, and the horizontal and vertical positions can be divided into equal parts. This transformation can be applied to images as well as shapes.

8 is a conceptual diagram illustrating a principle of deformation of an image to be expressed using a system according to the present invention.

Arranging the vector and the color information in the direction represented by the horizontal line in Fig. 8A results in an image of a shape indicated by the outline. Here, if the color information is left as it is and only the vector byte is changed to an oblique line as shown in FIG. 8 (B), an image rotated by a corresponding angle is obtained.

9. Divide large images into smaller ones

9 is a conceptual diagram illustrating a partition in which an image is divided into three parts A, B, and C.

Since the image file by the structure of the vector pixel 10 according to the present invention can define a new position, a new ID, and a new format anywhere in the data without specifying a special format, several images can be mixed in succession. have. Therefore, the three parts A, B, and C can be mixed into images of different formats by assigning IDs.

In particular, since the C part is a square image, the bitmap identifier can be assigned to the header type or control and saved as a separate file or partial image. At the end of the partial image, the RETURN command described above becomes an independent image. One example of efficient full image placement is to arrange a set of CALL commands that call all partial images at the beginning of a file, but there are many other ways.

The partial image may be divided into flat portions, may display layers at the same position, may display channels for each color, or may represent frames of a video. You can also divide the background and surface pictures by assigning a Z-index (display priority) as the control character.

10. Implementation of 3D Images

10 is a conceptual diagram illustrating a method theory for implementing a 3D image according to the image processing system according to the present invention.

As shown in FIG. 10, when the lower 4 bits, that is, the vector information unit 11 is the X, Y axis, and 2 bits among the upper 4 bits are Z axes, the components 'forward' and 'after' are added as shown in FIG. You can express dimensional coordinates. Although shown in the figure, the direction vectors increase to 26 instead of eight.

Since 0xf0 of all control characters 21 sets all the upper 4 bits, this results in setting all 2 bits of the Z-axis vector. This is because the direction vectors opposite to each other are set at the same time. That is, even in the case of a three-dimensional image, the control character 21 can be written.

In order to display a 3D image on the screen, each point must be converted to 2D coordinates. Depending on the direction of the observer's eye, the basic six types (up, down, left, right, front and back) of the 26 kinds of vectors should be converted into proportional calculations. Since the existing coordinates are absolute values, they have to be converted to multiplication division, but since the vector data represents an increment, it is possible to determine whether to reflect or ignore the increment. For example, when 1/6 of X coordinate is to be subtracted from Z coordinate, X / 6 should be calculated in case of absolute value, but in case of vector, it is ignored until right (→) appears 5 times and then appears 6th. It means that it is reflected.

It can integrate the front and top views of a drawing in a drawing, integrate parts and assembly drawings, and integrate drawings and projections. If you give each part a unique number as a control, you can print only the part drawing or you can print the whole part. During assembly drawing, it is easy to detect interference with nearby components, which makes the design easier. This can be applied not only to the imaging field but also to industrial design or surface analysis of NC machines.

11. Editing using vector synthesis of upper and lower bits

By using the bits for the control command information of the control unit 20 as a buffer, the independent unit vectors are listed, and the upper and lower vectors are synthesized and moved to obtain an editing effect. For example, if the lower vector is "imaginary image," a straight line of 4 pixels that rises vertically. If the vector "woo" is added to the upper bits of the corresponding byte and interpreted at the same time, it becomes "idol idol." It will be a straight line tilted 45 degrees to the upper right. The format of the header specifies the parent vector dependent shift, which is for this case.

Of course, there is a premise that you must properly create a pointer movement function that moves the current position. If an additional vector appears to offset the original data, the pointer will be in place and will move 2 pixels when the same component as the original is added. If there is no movement, then the next data reading and moving 2 pixels need to return the coordinates twice.

This is the same principle as 'deformation (magnification, reduction, rotation) of curves and images' described in 6 above, but the case is different. In 6, the original picture is transformed, but in this case, the original picture is transformed by combining it with the independent vector shown in the parent vector when drawing on the screen. In some cases, editing effects may be combined with external strings, which are not separately noted. In each case, their use and characteristics are different.

(1) In the case of the original change (contents of '6'), the quality can be improved by performing a smoothing process on the edited result.

(2) When combined with higher vectors, it can be used when numerous modifications are required for a single original.

(3) Can be used when it is necessary to express different shape depending on the situation for the original which cannot be combined / modified with independent external vector.

All three correspond to the case of figures or images. Arbitrarily deformed shapes can be obtained for a blade of grass or hair, and each can be used for an online game that needs to process a lot of image information.

12. Program the image

It has already been explained indirectly above that it is possible to assign a unique number to a picture and assign a call command to the control to call another picture and draw it repeatedly as many times as desired while drawing the picture. The addition is a call condition. The first byte of the control character CALLGRIM parameter (bytes remaining in the 4-byte block except for the command character) is the call condition. It ANDs the call switch byte in mode at the time of the call to determine whether it is called. What kind of switch is in place and how and when to turn it on and off is the point of programming.

When a picture is called and executed (screen display or motion picture execution), when the RETURN command is followed, switching on or off the next associative equivalent picture can continue any operation. For example, if you put a parameter to switch on the shield picture at the end of the sword-wielding video, two pictures appear in succession.

By defining one type of file in the header level type or mode, you can create an image that moves along a vector of externally provided curved strings. This can be done by concatenating the Pini in the header to the current position of the curve string. Of course, the length of time to move one point should be set as a base.

Types of pictures include ROUTE to move along another picture, REGION to create a section on the screen, PATH to make them, moving ANIMATION, LIBRARY to collect caller thumbnails, and DUMMYGRIM to collect only calling commands.

13. Create overlap picture using vector of high / low bit

Although various cases of using the upper four bits in the vector pixel 10 of 1 byte unit have been described, the most common use will be the case of writing as a separate vector like the lower vector. In other words, two points are represented by one byte. In the case of figures, the memory requirement will be cut in half, so it is applicable to the field where fixed and small memory requirements such as font definition are large.

In the case of an image, color information must be managed in duplicate, so it is not suitable for simply displaying 2 pixels. Therefore, it is suitable for displaying a single color shape such as an arrow or a symbol on an image. When viewing a subvector as an original image, it can be used to hold additional information without damaging the original.

Even when two straight lines or curves move to form a certain shape by symmetrical symmetry or a certain rule, a layered picture can be realized by moving the upper and lower bits independently. It can also be applied if you need to fill the color between two points with some rules.

14. Characters can be mixed

The image processing system according to the present invention has several functions for inserting text into image information. Of course, you can also draw a glyph with the parent vector as if you were drawing an arrow, but this is more a picture than a letter. Inserting as character information is by control character.

Three kinds of control characters 21 which can put a character are provided. 2-byte, 3-byte, and infinite length instructions. The two-byte and three-byte commands only need to insert character information of that length after the control character, so no longer explanation is required.

The problem is the infinite length command. 0xff is a special control character that is basically recognized as string information until the next 0xff. If the character immediately after 0xff is not defined as a kind of control in the header or other set mode, it means that it is recognized as string information. Since there is no less than 32 in the string data, there is no particular conflict with the data system of the method according to the present invention.

The default font size is designated as the file-level control character 21 (the control character for this is not illustrated in detail), and the character size can be adjusted with the up and down vectors according to one-point increment. The direction vector is not needed inside the string because the position where the character will be printed would have been managed as a coordinate vector before 0xff appeared. Thus, vectors can be used to manage font sizes. Of course, higher vectors cannot collide with string data.

Although not described in detail, if the first byte after 0xff is defined as a control character (21) and a rule is provided to control necessary parameters such as font type, font size, and character color, finely managed string information may be embedded. Could be.

15. Time series editing of video using control bits

By changing the value of the CALLGRIM switch bit of mode automatically according to the time flow of the clock in the automata program, it is possible to automate the change of the brightness of the video according to the time of day and the change of the shadow according to the direction of the sun. It is possible to automate the change of season, wind direction, etc. according to the change of control bit.

As a simple example, call pictures can be set up as two types (or more) of a bright picture, a dark picture, and the brightness is controlled by switching on the bright picture and switching off the dark picture over time. . Of course, for finer operation, as described in section 10, a kind of picture may be separately provided and a brightness control program may be incorporated.

As described so far, the configuration and operation of the image processing system using the vector pixel according to the present invention have been expressed in the above description and the drawings, but this is merely an example, and the spirit of the present invention is not limited to the above description and the drawings. Of course, various changes and modifications are possible without departing from the spirit of the present invention.

As described above, according to the image processing system using the vector pixel according to the present invention,

1) By reducing the computer memory storage capacity of image data, it not only reduces the capacity of the main memory and disk device of the computer, but also has the advantage of improving the processing speed and data communication time due to the reduction of data.

2) In the field of animation or online games that need to handle and prepare a large amount of image information, there is an advantage that the amount of work can be drastically reduced by the development of program tools such as automata for making video materials or videos. ,

3) The application of three-dimensional drawings in the industrial sector can be applied to a comprehensive application CAD program without assembly and parts, and the analysis of three-dimensional curves can be used to develop programs for the operation of computer-controlled machine tools. ,

4) Others, such as montage to change the local parts of the image, maps that need to be reduced and mixed with lines, outlines, text information, etc. can have a significant effect.
