溢位产生装置6,是连接在马赛克效果处理装置5的图形座标(X、Y)输出端,可在检测出图形座标已超过图形大小时,产生一溢位输出信号,以控制影像的输出。 Overflow generating means 6, is connected to the mosaic processing graphics coordinate (X, Y) output terminal means 5, can be detected when the pattern size exceeds the figure coordinate generating an overflow output signal, for controlling the image output.

从前述整个马赛克效果处理的图像合成装置的结构来看,基本上以二维转换装置28及马赛克效果处理装置5送出处理后的代表屏幕座标的图形座标而经一索引读取装置14产生一索引地址信号,以读取内存装置10中的索引数据、调色盘、水平/垂直镜射数据,再将数据送入至图形读取装置20,合成为图形地址信号,以读取图形数据,并将读出的各项数据经色码选取/合成装置26、30合成为色码输出信号,提供一种以像素为单位的图像合成装置,可送出符合马赛克效果图形缩放、旋转等作用的信号型式。 From the structure of the entire image compositing apparatus mosaic processing perspective, substantially two-dimensional conversion device 28 and the mosaic pattern processing apparatus 5 sends ordinate represents screen coordinates after processing by a reading means 14 generates an index index address signal, memory means to read the index data 10, palette, horizontal / vertical mirror data, then the data reader 20 is fed to the graphic, the graphic address signal is synthesized to read graphic data, and the data read out by the color code selecting / combining device 26, 30 is a synthesis signal output color code, providing a signal line with a mosaic effect image resizing action, like a rotating image synthesis apparatus in pixels units, can send type.

在绘图模式(GRAPHIC MODE)或文字模式(TEXT MODE)下,由于两种模式的基本差别,其数据处理过程也存在差别。 In the drawing mode (GRAPHIC MODE) mode or text (TEXT MODE), due to the fundamental difference between the two modes, the data processing procedure there are also differences. 在绘图模式下,图形数据是以位对映(BIT MAP)方式存放在内存装置10中,故只需经过前述马赛克效果处理装置送出的图形座标,配合颜色模式、图形大小,便可决定图形数据的存放位置,故实际上无需利用索引数据再对映产生,故在绘图模式下,该图形读取装置20无需使用索引数据,便可直接合成为图形读取地址信号,以读出内存装置10中的图形;而文字模式则由于文字及图形采用“间接对映”型态(即图3的PNT与PGT的对映关系),故需经过两次读取作业:即先读取索引数据再读取图形数据,以读取正确的文字图形。 In graphics mode, the graphics data is mapped bits (BIT MAP) mode stored in the memory device 10, it is only after feeding the mosaic pattern processing apparatus coordinates with the color mode, image size, the graphic can be determined storage of data, so the data without actually using the index mapping is generated again, it is in the drawing mode, the pattern reading means 20 without using the index data, the graphic can be directly synthesized to read address signals to read out the memory device the pattern 10; and the text mode due to use text and graphics "indirect enantiomer" type (i.e., FIG. 3 PNT with the PGT enantiomer relation), it takes twice the read job: that is, first read the index data re-read graphical data, in order to read the correct text graphics. 在文字模式下,不同字形(FONT)大小、图框(PAGE SIZE)大小的图形名称表PNT的地址表示方式如图4所示,图5则显示文字模式下,在不同字形(16×16、8×8)及十六色状态下,图形表PGT地址为通过索引值INDEX表示的型态,图6显示在绘图模式下,不同颜色模式(256、16、4、2色)供读取内存装置10的图形表PGT的地址信号的型态,而此图中显示只有图形表地址信号及图形座标(X、Y)信号。 In text mode, a different font (FONT) size, frame (PAGE SIZE) the size of the name table PNT graphical representation shown in FIG address, in FIG 54 is displayed in text mode, different in shape (16 × 16, the 8 × 8) and sixteen colored state, graphics table PGT address by an index value iNDEX patterns indicated, Figure 6 shows the drawing mode, different color mode (color 256,16,4,2) for reading the memory type device address signal pattern of table PGT 10, only the display pattern table address signal and the graphic coordinates (X, Y) signal in this figure.

本发明的马赛克效果处理装置5将二维转换装置28产生的图形座标(X′、Y′)再予以转换为马赛克效果处理的图形座标(X、Y)的实施例,如图7的经马赛克效果控制信号设定为4×4方块大小的图形座标格式所示,即在图中以上、下分别为处理前及处理后的X、Y座标内容,亦即分别使X、Y座标的最低两位(位1、位0)位置,经逻辑电路将其维持在“0”状态(亦可设定为“1”状态),故可使该相应的区块呈现同一颜色,且该颜色值也可通过前述使该位设在不同“0”或“1”的状态,使马赛克效果的区块可选用区块内任一图点颜色值为代表,亦即如图9、10所示,可将图面上方4×4图点区域内各不同颜色的图点,选择任一图点的颜色值作为整个4×4区域的同一颜色,而实际运用在图形上的效果如图8所示,图面左侧为未经马赛克效果处理的图形,右侧位置是以图面分割的区块 Mosaic effect processing device 5 of the present invention a two-dimensional pattern coordinate conversion means 28 generates the (X ', Y') and then be graphical coordinate (X, Y) into a mosaic effect process in the embodiment, as shown in FIG. 7 mosaic effect by the control signal is set to 4 × 4 block size as shown in figure coordinate format, i.e. in the figure above, respectively, the X, Y coordinates and the contents after the pretreatment process, i.e. respectively X, Y the lowest two coordinates (bit 1, bit 0) position, after which the logic circuit is maintained at "0" state (may also be set to "1" state), so that the respective blocks can exhibit the same color, and the color value may be provided so that different bit "0" or "1" of the mosaic tiles by any one of the preceding FIG point color values ​​can be selected representative of the block, i.e., 9, 10 shown, may be of various colors inner surface side in FIG. 4 × 4 dot area in FIG. FIG point, FIG select any point color values ​​of the same color as the entire region of 4 × 4, the actual application of the effect on the graph in FIG. 8, the left side of FIG pattern mosaic effect without treatment, a right position in FIG surface is divided block 小为处理单位,选定各区块其一图点的颜色值的表示。 The processing unit is small, the selected color value of each block represents one point in FIG.
