It is characterized in that the color appearing on the display unit is adjusted by converting the changed color data into the display unit.

Next, the data format of the compact disc will be described with reference to FIGS. 1 and 2 to help understand the present invention before explaining the present invention.

Compact audio discs generally contain information about music, and data can be divided frame by frame. One frame is composed of 24 bits of frame synchronization signal, one subcode symbol, 24 symbols of data, and 8 symbols of physics. When one symbol is recorded on a compact disc, it is recorded in 14 bits, but it is 8 bits that actually represents information among the 14 bits. FIG. 1 shows the type of data stored in eight bits of the subcode in a group of 98 such frames.

Referring to FIG. 1, the subcodes of the first frame and the second frame contain subcode synchronization signals for distinguishing 98 frames. The eight bits are referred to as P, Q, R, S, T, U, V, and W channels, respectively. The P and Q channels usually contain information for finding the progress of each song, such as the absolute time of the compact disc, the relative time of each song, the track number, and the starting point of the song. The pickup will be controlled. The R, S, T, U, V, and W channels contain data for graphics. The 96 subframes are divided into four packs, and the basic form of the pack is shown on the right side of FIG.

The pack consists of 24 subcodes, which will be described as SYMBOL-0 to SYMBOL-23, respectively. The symbol SYMBOL-0 represents a mode and an item by 3 bits each, and designates a graphic purpose. The number of indexes that can be specified is 2 ⁶ or 64, but six graphic data shown in Table 1 are designated.

Here, in order to make the description of the present invention clear, the case of the TV-graphic mode among the graphic modes will be described as an example, and the color adjustment method in the CDG-processor for performing TV-graphics will be described. However, it is easy for one of ordinary skill in the data processing arts to carry out color change under the same idea even in modes other than TV-graphics.

The symbol SYMBOL-1 represents the instruction (INSTRUCTION), and the type of the instruction used in the TV-graphics mode is shown in Table 2 below.

Symbols SYMBOL-2 to SYMBOL-3 and SYMBOL-23 to SYMBOL-23 are parity Q and parity P symbols for error correction, respectively.

The symbols SYMBOL-4 to SYMBOL-19 are data storage portions, and the data to be stored varies according to the instructions shown in Table 2 above. Among them, Preset Memory, Preset BORDER, Data Writing to Font (Write FONT FOREGROUND / BACKGROUND), Soft Scroll Screen Preset (Soft Scroll SCREEN, With) preset), changing the contents of the upper address in the color mute table (Load the CLUT, color-0..color-7), and changing the contents of the lower address in the color mute table (Load the CLUT, color-0..color-7) Data formats are shown in FIGS. 2A to 2F, respectively, which will be described in conjunction with the block diagram of the CDG processor shown in FIG.

First, FIG. 3 shows a block diagram of a compact disc system including a CDG processor. The compact disc 301, the digital signal processor (DSP) 302, the CDG processor 304, the image memory unit 310, and the display unit are shown. 309, the CDG processor further includes a subcode interface 305, a deinterleave unit 306, an error correction CDG- (ECC) 307, and a graphics processor 308.

In FIG. 3, the digital signal processor (DSP) 302 deinterleaves and reads data read out from the compact disc 301, and separates the data into audio data and subcode data according to channels. In this way, the data applied to the CDG-processor 304 is applied to the deinterleave unit 306 via the subcode interface 305, deinterleaved again, and then an error coded in the subcode in the error correction unit (ECC) 307. Error correction according to the correction code is performed and converted into graphic data in a form for processing by the graphic processor 308. The graphic data referred to here has a form as shown in FIG. The graphic processor 308 uses the image memory unit 310 and the color mute table to perform the graphic processing according to the instruction (INSTRUCTION) of the graphic data. The image memory unit 310 is a part in which information about an image to be burned by the CDG has a one-to-one correspondence relationship, and a color mute table is a memory used as an intermediate medium for efficiently processing color information. It is embedded in the processor 308. Detailed description thereof will be made with reference to FIGS. 4 and 5. Of the graphic data described above, graphic data related to the color mute table will be described next.

Referring to FIG. 2A, data about a color consisting of 4 bits is included in the T, U, V, and W channels of the symbol SYMBOL-4 as data related to the preset memory. When such data is read out from the compact disc, processed digitally, and then applied to a graphics processor included in the CDG processor, the graphics processor applies the data to the image memory unit to preset the contents of all fonts in the image memory unit. The image memory unit stores portions of image data to be expressed by the CDG processor, which will be described in detail with reference to FIGS. 3 and 4. On the other hand, the data of the 4-bit color is an address applied to the color mute table, which will be referred to as a color address hereinafter. In addition, data as shown in FIG. 2A is stored in 16 consecutive packs on a compact disc, and the number of repetitions on the T, U, V, and W channels of the symbol SYMBOL-5 is the number of repetitions.

Referring to FIG. 2B, a color address is loaded on the T, U, V, and W channels of the symbol SYMBOL-4 as data related to the preset BORDER. When such a color address is applied to the color mute table, color signal strength (hereinafter referred to as color data) consisting of 12 bits of 4 bits each of R, G, and B can be obtained, and the graphics processor 308 uses the 12-bit color. The data is applied to the display unit 309. In this case, the display unit controls the screen according to the border area and the screen area. In the case of the border area, the display area is expressed according to the color data applied from the color mute table, and in the case of the screen area, the graphic corresponding to the image memory part is represented. .

Referring to FIG. 2C, data about writing data in a font (Write FONT FOREGROUND / BACKGROUND) is recorded. The T, U, V, and W channels of SYMBOL-4 use 4-bit first-color address. The T, U, V, and W channels of the symbol SYMBOL-5 designate 4-bit second color addresses. The first color address is an address in which the color of the background (BACK GROUND) designated as 0 is stored among the data of the font defined by the symbol SYMBOL-8 to SYMBOL-19, and the second color address is the font. The foreground color designated by 1 in the (FONT) data is stored in the address. The S, T, U, V, and W channels of symbol SYMBOL-6 represent 5 bits of ROW address among the font addresses of image memory, and the R, S, T, U, V of SYMBOL-7 symbols. The W channel represents a 6-bit column address of the font address of the image memory. In the drawing, y corresponds to a pixel located at the uppermost left side of the pixels included in the font of the image memory, and z corresponds to a pixel located at the lowermost right side of the pixels included in the font of the image memory. Therefore, the graphic to be expressed is represented as data 1 on the font and other portions are represented by 0, so that a character or a figure can be represented, and the color is designated as the first-color address and the second-color address. .

Referring to FIG. 2D, data relating to a soft scroll screen preset (Soft Scroll SCREEN, With preset) is shown, and data for controlling the scroll operation of the image memory unit is loaded. At this time, the fonts on the image memory portion that is scrolled and left blank are preset to the color designated by the four-bit color address contained in the T, U, V, and W channels of the symbol SYMBOL-4. In addition, COP-H and COP-V represent horizontal and vertical scrolls, and PH and PV represent horizontal and vertical shift pointers, respectively.

Referring to FIGS. 2e and 2f, the contents of the upper address on the color mute table (Load the CULT, color-0..color-7) and the contents of the lower address on the color mute table (Load the CULT, color-8 .. color-15). The content of the color mute table is composed of 12 bits, and since the graphic subcode is composed of 6 channels, that is, 1 symbol is composed of 6 bits, two symbols correspond to address 1 of the color mute table.

Therefore, when the instruction INSTRUCTION is 011110, the contents of address 0 to address 7 of the color silent table are newly written, and when 011111, the contents of address 8 to address 15 of the color silent table are newly written.

4 shows the image memory unit 303 shown in FIG. 3 specifically, and has a size of 18 x 50 fonts. The font, which is a basic unit, is composed of pixels one-to-one corresponding to data bits in the font areas in FIGS. 2E and 2F. In other words, one font has a size of 12 x 6 pixels. The outermost fonts of the image memory unit 303 are not displayed on the screen but are merely used as areas for scrolling operation. Therefore, the parts of the image memory unit 303 represented in the screen area on the screen are COLUMN1 to COLUMN48 and fonts corresponding to ROW1 to ROW16. In addition, the image memory unit 310 stores the color address for the image to be displayed according to each instruction of the graphic data as shown in FIG. This has the effect of efficiently using the memory. That is, instead of storing 12-bit color data, 12-bit color data is stored in the color silent table and only 4 bits of the color address, which is its address, are stored in the image memory unit 310. This increases the storage efficiency by about 300%. This method also has the advantage that a special screen effect can be obtained by gradually increasing or decreasing the color data of the color mute table, and it is possible to change the color displayed on the screen at one time.

Meanwhile, referring to FIG. 5, the configuration of the color mute table is a memory unit included in the graphic processor 308 of FIG. 3, and the size is 16. That is, the color address as the address line is composed of 4 bits, and one address stores 12 bits of color data. That is, the data for one color is composed of 12 bits. As shown in the drawing, red (R) is 4 bits, green (G) is 4 bits, and blue (B) is 4 bits. Here, the number of color branches that can be represented by 12 bits is 4096, but the number of color branches that can be easily identified by an ordinary person is much smaller than this. The graphic processor 308 selects 16 colors to be displayed on the screen among the colors represented by 12 bits and stores 16 color data thereof in the color mute table. After that, if the color address is designated, the color data stored in the color mute table can be read. In this case, the color silent table is in a lead state, and the contents of the upper address are changed in the color silent table described in FIGS. 2e and 2f (Load the CLUT, color-0..color-7) or the lower address is in the color silent table. In the case of a content change (Load the CLUT, color-0..color-7), the color mute table is live.

Herein, the read state will be described in more detail. Color addresses (4 bits) sequentially read from the image memory unit 310 are sequentially applied to the color mute table and converted into corresponding color data (12 bits). . The color data (12 bits) thus obtained is applied to the display unit 309. On the other hand, in the live state, the contents of the instruction (INSTRUCTION) of the graphic data change the contents of the upper address in the color silent table (Load the CLUT, color-0..color-7), and the contents of the lower address in the color silent table (Load the CLUT, color-0..color-7), the contents of the color mute table are updated.

Here, the 12 bits of color data are formed by combining two symbols as described in FIGS. 2E and 2F.

As described above, in the CDG, the color has a two-step structure in which the color address and the color data stored in the color mute table are read out by the address. It can be seen that by converting, it is possible to achieve the object. In addition, all the color data (12 bits) applied to the display unit 309 are outputted from the color mute table, and the object of the present invention can also be achieved by converting the output of the color mute table to the display unit 309. It can be seen that.

FIG. 6 is a block diagram of a CDG processor to which the color adjustment method of the CDG according to the present invention is applied, and further includes key input means 601 for inputting color edit signals by an external or user other than the configuration described in FIG. It will be included.

In FIG. 6, the key input means 601 is a means for inputting an external selection. As a result, the user inputs an index raw color to change the color displayed on the screen through the key input means 601, and the result of the change. You can select the index change color that you want to display on the screen. For example, if you want to change red to yellow, you can choose red as the primary color and + yellow. This can be done with a conventional remote control, a keypad with a color name, etc. The color name can be a number or a sign. The key input means 601 outputs the color change mode signal to the graphic processor 308 so that the graphic processor 308 knows the information about the original color and the changed color and the color to be changed from the outside. Done.

Hereinafter, an embodiment of the method performed by the key input unit 601 will be described. First, there are two methods of color change: a method of changing a color address applied to the color mute table and a method of changing color data output from the color mute table and applied to the display unit. Therefore, the color change mode signal applied to the graphic processor capable of performing both the above methods indicates three modes. An example in which the color change signal in this case is composed of two bits of C and C is shown in the following table.

That is, when C of the color change mode signal is 0, the color on the screen is only displayed according to the data output from the compact disc 301. When C is 1, it indicates that the color is editable from the outside. The color editing is divided into two cases. When C is 0, the color address applied to the color mute table is converted. In the case of 1, the signal output from the color mux table is converted.

First, a method of converting a color address applied to a color mute table will be described. When the user selects such a mode, a raw color, and a change color, the key input unit converts the raw color and the changed color into a raw address and a change address, respectively, corresponding to the 4-bit address, and apply them to the graphic processor. .

For example, when the color data 'red' is stored in the color address 2 of the color mute table as shown in FIG. 8a, and the color data 'yellow' is stored in the color address 8, the primitive color is displayed by the user. Assuming that the red color or the change color is input to yellow, the key input means 601 is 2 = (0010) as a raw address and 8 = (1000) as a change address and as a color change mode signal (10). ) Is applied to the graphics processor 308. The graphic processor 308, which receives the color change mode signal, the raw address, and the change address from the key input means, is stored in the image memory unit 310 and applied to the color mute table or the preset report. It is determined whether the color addresses according to the order format are the same as the original addresses, and if they are the same, the color addresses are converted to the change addresses and applied to the color mute table.

Secondly, in the case of changing the color data output from the color mute table, the key input means sets the color change mode signal (11), and comprises 12 bits each of the original color and the changed color selected by the user. After converting the raw color data and the changed color data, the color change mode signal, the raw color data, and the changed color data are applied to the graphic processor 308. The graphics processor 308 determines that the color change mode signal is the color data change mode to determine whether the color data read out from the color mute table and applied to the display unit 309 is the same as the raw color data. This is converted into the changed color data and then applied to the display unit 309.

Here, in the method of adjusting the color on the screen by changing the color address, an embodiment in which a plurality of colors to be changed by the user will be described with reference to FIG. 8B.

8B shows a change address table, which is a means used when the color change mode signal is (10). The change address table is a means for storing change addresses having a one-to-one correspondence for each color address. If there is no color to be changed from the outside, the color address itself becomes the contents. In other words, the change address table is 2 if the color address is 4 bits. = 16, the contents of which are 4-bit change addresses. As an example, as shown in FIG. 8A, the contents of the change address table are shown on the right when a color mute table is configured, and when red is changed to yellow from yellow and red is changed to red from the outside. The second address of the change address table contains the binary number 1000 of 8 and the eighth address contains the binary number 2 of 2. If the color address is applied to the change address table when the color address table is in the read state after the change address table is created in this way, the color address is changed to the change address, thereby changing the color data read from the color silence table. Here, the color data read out from the color mute table may be digitally converted into D / A as digital data, applied to the display unit 304, or continuously processed in digital form, and then converted into analog in the display unit 309.

FIG. 7 is a diagram showing an embodiment of a TV screen in a CDG in which the TV screen represents an image according to TV-graphic data. In addition, line graphics can be displayed, and graphic data contained on the compact disc has a VD area in addition to the sub-code of the CD area, so that the border area can be displayed without moving to one color. However, all of the above examples include processing graphic data of the subcode area of the compact disc, and the color designation consists of a two-stage structure using the color address and color silence table as described above. Applicable Referring to FIG. 7, the screen configuration in the case of TV-graphics can be divided into a screen area and a border area. The screen area is a part in which the image corresponding to the color data stored in the color address stored in the part of the image memory unit 310 except for each font in the outer part is expressed, and the border area is packed data read from the compact disc. Is a part that is set to the color obtained by the color address included in the case of the order reset. In this case, the screen area expresses a character or a still picture, not a moving picture in which an image changes rapidly.

9A to 9C show a flowchart of the graphic processor 308 performing the above-described method. The graphic processor 308 first determines a color change mode signal in operation 901 and then performs operations according to each mode. To perform.

Referring to FIG. 9B, the color address change mode execution step 903 is shown in detail. In step 905, the raw address and the change address are inputted from the key input means 601. It is determined whether the table CLUT is in the 'READ' state or the 'WRITE' state. If the table CLUT is in the 'read' state, the process branches to step 909, and in the case of the 'light' state, step 907 Branching to update the contents of the color mute table. In operation 909, if the color address applied to the color mute table is the same as the original address, and if the same is the same, in step 910, the change address is applied to the color mute table and the corresponding color data is displayed on the display unit 309. Otherwise, the color address is applied to the color mute table as it is without changing the color address, the color data corresponding thereto is read, and then applied to the display unit 309.

Referring to FIG. 9C, the color data change mode execution 904 is specifically illustrated. In operation 911, raw color data and change color data are input from the key input means 601. Determines if the color mute table is in 'lead' state.

Only in the 'lead' state, the process branches to step 914 to determine whether the color data is the same as the original color data, and if it is the same, the changed color data is applied to the display unit 309 in step 916. In step 913, when the color mute table is in the 'write' state, the contents of the color mute table are updated. In operation 915, the color data is different from the original color data. At this time, the color data is applied to the display unit 309 without any change.

On the other hand, the color mux table changes the contents of the upper address to the color mux table read from the compact disc (Load the CLUT, color-0..color-7) and the contents of the lower address to the color mux table (Load the CLUT, color-0. The color is updated according to .color-7), so that it is not easy to select the original color and the change color through the key input means 601. In other words, even if the user selects the original color and the changed color, the generation of the original address and the change address is not easy. In this case, the remedy means includes a means for reading the contents in the color silent table in the key input means to determine the color thereof, and generating a corresponding address when the original color and the changed color are input by the user. There may be one. Another solution may be to have the user enter the raw address and the change address directly. This allows the user to input the source address and the change address directly by using the color markup table color display means, which means that the user can know the color of the color markup table. Enter the corresponding code. An example thereof will be described below with reference to FIGS. 10A to 10C.

FIG. 10A shows a block diagram according to an embodiment of the color mute table color display means, and is composed of an auxiliary mute table 1001 and a color mute table color display part 1002. As shown in FIG. The auxiliary mute table 1001 performs a write operation simultaneously with the color mute table when the color mute table is in the 'write' state, so that the same color data as the color mute table is stored. The color mute table color display unit 1002 is a portion in which the color mute table reads the contents of the auxiliary mute table 1001 and displays them. The method of displaying the color name of the display device, such as a liquid crystal panel, and the index corresponding to the address on the silent table together, or displaying them as color bars separated by a certain interval in the order area of the TV screen. There may be.

FIG. 10B is a diagram showing a color display of a color mute table using a TV screen, and is expressed as 0, 1, 2, ... 14, 15, etc. instead of a user directly inputting a raw address or a change address. The input index is input, and the key input means converts it to a raw address or a change address having a one-to-one correspondence. For example, red may be displayed at the point indicated by the index 2 at some point, but may be displayed at the index 12 and the like at the next point. In this case, the primitive address or change address is input as 2 or 12 for each input point.

FIG. 10C illustrates an example of a detailed block diagram of a color MUT table (C-LUT) color display unit, and includes a color name generation unit 1993 and a name display unit 1004. The color name generation unit 1003 generates a color name corresponding to the color data read out from the auxiliary mute table 1001. Color data is represented by 12 bits and 2 Branches, or 4096 branches, can be expressed, but there is a point that almost no distinction is made when there is a slight change in signal strength.

Therefore, since a certain range of color data has the same color name, after setting these conditions in advance, each time color data is inputted, it is determined to generate a color name corresponding thereto. The name display section 1004 is a block for displaying the color names output from the color name generating section 1003 on a display device such as a liquid crystal lamp.

Here, a more practical problem will be described regarding the process of comparing color data and raw color data in the color data changing mode. As described above, the color data represented by 12 bits is 2 As for 4096 things, the average person cannot tell the difference between them. Therefore, if the data displayed in red on the screen is of what color color and I want to change it to yellow, it is practically impossible to know what color data should also have. In this case, since the raw color data is one of the color data stored on the color mute table, the auxiliary mute table and the display device for displaying the same are used in the same manner as above, and the user selects one of them. Color data values can be generated as raw color addresses.

Unlike the raw color data, the change color data can be freely selected from 4096 types, so that a memory capable of storing only 12 bits is designated separately from the auxiliary mute table, and the contents of the memory are continuously changed by external adjustment. Do it. In this case, in order to allow the user to know the color indicated by the color data stored therein, the corresponding color is displayed on the liquid crystal display means or a part of the TV. When the 12-bit color data stored in the memory is output as the change color data.

As described above, the present invention has the advantage of improving the function of the CDG by enabling the user to freely change the color displayed on the screen in the CDG. In addition, the present invention can be applied to other fields besides CDG. In other words, it can be applied to any system that stores color data in memory and assigns a color using its address.
