Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy Field of Invention: ^^ Month is a corresponding device that produces special effects on the screen. More notably, the present invention relates to a corresponding device used to connect to a raster type display controller (Note 1), and a scanning display is used to produce special effects. Note 1: Scanning display controller, cathode ray tube controller or crtc is an example. BACKGROUND OF THE INVENTION: Conventional display devices usually include an iinecounter that generates a horizontal scanning line start address. The starting address of the horizontal scanning line will be sent to the memory counter (mem〇ryc〇unter), and this memory counter is used to generate the address of all points of a certain oblique line . The other type of display controller provides two registers: a shift register and a starting address register; and the two registers are used to achieve the horizontal and vertical picture. Pan effect. All the above-mentioned display devices adopt a linear processing method for the start address of each scanning line. Another type of display controller is also widely used by scanning type indicators. For example, the image display controller (image-type display controller) on TV game instruments also uses this type of display controller. Pu Mian Gu Qian divides the 256X25 __- sized camp curtain into ^ an image or an object). An 8x8 pixel-sized character can be displayed in a 32 Magic 2 area.

The purpose is to distinguish whether the input milk ruler attribute is an absolute address (the actual window start address is related) or the relative address is related to the positive line). If the V bit is equal to 丨, the fiber address ^ is direct). On the other side, if the V bit is equal to 0, the address is a relative base f bit f. Before considering the effect of horizontal displacement, the start of each scanning line = the counter must add the value of line_number χN (丨 ine—number is the number of the scanning line displayed by the mesh, and N is the width of the virtual window shown in Figure 1 ). Because the width of the virtual window is basically the width of the display device and can usually be expressed in 2m (512, 1024, etc .; m = l〇g2N), it can be considered that the start address of each scan line is shifted, that is, eight ^ + this ^ Stomach ^^ !!!, and ADR can also be regarded as vertical translation or vertical displacement. In summary, the starting address of the memory counter of each scan line can be expressed by the following formula: memory counter starting address = (V)? ADR: ADR + line_number X 2m That is, if (V == l ) Memory counter start address = ADR; otherwise memory counter start address = ADR + line_number X 2m In complex screen effects (such as perspective or 2D / 3D rotation), the absolute vertical translation (V bit = 1) is needed. 14 f-袭 ------ Ιτ ----- {ix (I understand the precautions on the back and then fill in this page) The standard of wood paper is applicable to the Chinese national standard (CNS > Α4 specification (210Χ297mm) 83. 3.

Description of the Invention (丨 丨) ~~~ --- Figure 6B is the corresponding method of the present invention when using multiple windows to express another water baud effect. The scan lines in the two windows correspond to the same index. This example uses the same attribute matrix as Example 3. The main difference between this example and Example 3 is that the second address shift generator generates a shift register Its content is "1". This also causes all the index bit 1 of the index matrix to increase by "1." As shown in Figure 6B, we can get a different water wave. Example 5 Figure 7 shows a rectangular window for the present invention Corresponding way of showing the three-dimensional perspective effect. In this example, each scan line is given a set of individual SCALE (from S [0], S [l], ... to S [K]), a group of individual / 的 ， OFFSET (From 0 [〇] '〇 [1], ... to [K]) and-a set of individual ADRs (from Y [〇], Y [l] '... to Y [K]). Because this example includes a greater degree of manipulation of attributes, the ADR value is based on absolute displacement (All V-bit attributes are "1".) Simply enter the appropriate OFFSET1 and OFFSET2 values, the screen can even move (forward or backward) or jump to a different screen. Example 6 Attribute matrix can contain different types Figure 8 shows the corresponding way of using X'Y'dX'dY and other attributes to make a rectangular window (with k scanning lines) exhibit two-dimensional or three-dimensional rotation (two-dimensional rotation plus perspective effect). In this example, X and γ are the absolute horizontal and vertical displacement of each scan line (the horizontal and vertical position of the first pixel after two-dimensional rotation), dY / dX is the slope of the rotation line, and | (dX, dY) | is 2-19-(please read the notes on the back before filling in this education)-pack. The paper size of the binding book is applicable to China National Standards (CNS) specifications (210X297mm) 83. 3. 10,000 305041 a? _ _B7 —__ Fifth, the description of the invention (enlargement and reduction parameters of the dimensional image display. For convenience of explanation, let ’s first look at the two scan lines 1 n, 1. and. In the first window , The starting position (coordinates) of scan line 10

UIK is (X1 [0], Ya chat. Similarly, the starting position of scan line 1 (coordinate _ is (X1 [I] 'i Y1 [i]). The two-dimensional rotation as shown (can be viewed In a top view), each scanning line has a common slope, that is to say, the slope of line 1 = slope of line \ • slope = line \ of one, one slope = dYU〇] / dX1 [〇]. Figure 7 The second window in the 'by using different 1 ^ and dY values can use the effect of perspective to achieve three-dimensional rotation. The corresponding device / corresponding method in the present invention has the following advantages: (a) It can be applied to two-dimensional / On a three-dimensional screen, linear manipulation can produce effects such as distortion and distortion on the screen image; ⑹ only need to use a single standard system 'software program to provide special effects; (0 can provide multiple window effects and (d) its operation No multiplier is needed, so the manufacturing process can be simplified.
