[Background of the Invention]. Some portable data processor products currently on the market, such as personal digital assistants (PDAs) or electronic word salvos / In order to increase the richness of product content, most of them will Designed with some simple games stored in it for users to use for entertainment, such as board games, or some simple two-dimensional games such as aircraft, Tetris, make these products more for entertainment purposes. Although this can provide users with some convenience, it is inferior to the rich games on the PC. _.The main reason is that there are no three-dimensional games on these products. The three-dimensional calculation requires a large amount of processing time of the processor. In addition to the fact that the CPU's operation speed is much slower than that of a PC, it will not be equipped with a graphics acceleration card commonly used on PCs, not even a floating-point calculator. The game design on these products is subject to many restrictions and cannot be as rich and enticing as PC games. Therefore, if you can say three-dimensional games under the inherent limitations of these products, I believe that this product can stand out from the crowd. · Come out and be favored by consumers. [Summary of the invention] In view of this, the main object of the present invention is to provide a method for implementing a three-dimensional game on a portable data processor, which uses non-uniform thumbnail images.

第6頁 454156 五、發明說明（4) 所謂景深，亦即人與景物的相對距離，所謂景深變化 就是說人與周圍景物的相對距離發生了變化，人們透過對 景深變化的感受而獲得自己的位置訊息。人們能感受景深 變化主要是因為遠處的景物在人的視網膜中所成的像比較 小，而近處的景物所成的像比較大，當人感覺到某處景物 逐漸變大的時候，他知道自己正在靠近那個景物，而當他 感覺到某處景物逐漸變小的時候，他知道自己正在遠離那 個景物。人們在生活：中還有這樣的經驗，當一輛汽車從遠 處駛過時，他會覺得那是缓缓移動，而當汽車從他身旁駛 過時，他會覺得那是風馳電掣。總體來說，遠處的景物看 起來比較小一些，但小卻不會讓人感到比例失調，近處的 景物看起來要大一些。根據這些常識，我們可以知道甚麼 樣的效果才讓人感覺到右景深並且景深在變化，從而設計 出實..現這種效果的方法，那就是前述所提到的非均勻縮圖 技術。 以「第1圖」為例，其中「第1 A圖」代表沒有景深 效果的原平面圖像，而「第1 B圖」代表經過非均勻縮圖 技術壓縮後的景物圖像，其右邊圖像高度比較小，代表較 遠處的景物，左邊圖像高度比較大，代表比較近的景.物。 處理縮圖的原則是，對相同景深的~部位採用相同的壓縮比 、 例，對於X方向座標相同的景物採用相同的景深加以處 理，因此所謂的非均勻縮圖，即是指水平方向與垂直方向 的壓縮比例不一樣，在水平方向，也就是X軸方向，採用 非均勻壓縮，垂直方向，也就是Y抽方向’採用均勻壓Page 6 454156 V. Description of the invention (4) The so-called depth of field, that is, the relative distance between the person and the scene, the so-called change of the depth of field means that the relative distance between the person and the surrounding scene has changed. Location information. People can feel the change in the depth of field mainly because the distant scene makes a smaller image in the human retina, while the close scene makes a larger image. When a person feels that the scene gradually becomes larger, he Knowing he was approaching that scene, and when he felt that the scene was getting smaller somewhere, he knew he was moving away from that scene. People also have the experience in life: when a car passes by from a distance, he feels that it is moving slowly, and when the car passes by him, he feels that it is galloping. In general, the scenery in the distance looks smaller, but the small one does not make people feel out of proportion. The scenery in the distance looks bigger. Based on these common sense, we can know what effect makes people feel the right depth of field and the depth of field is changing, so as to design a real .. The way to achieve this effect is the aforementioned non-uniform thumbnail technology. Take "Picture 1" as an example, where "Picture 1 A" represents the original plane image without the depth of field effect, and "Picture 1 B" represents the scene image compressed by non-uniform thumbnail technology. The image height is relatively small, which represents a distant scene, and the left image height is relatively large, which represents a relatively close scene. The principle of processing thumbnails is to use the same compression ratio for the parts of the same depth of field, for example, and to use the same depth of field for the same coordinates in the X direction. Therefore, the so-called non-uniform thumbnails refer to horizontal and vertical The compression ratio in the direction is different. In the horizontal direction, that is, the X-axis direction, non-uniform compression is used, and the vertical direction, that is, the Y-drawing direction, uses uniform compression.
第7頁 4 5 4 1 5 6 五、發明說明（5) 縮。 縮圖的基本操作是從原圖像中經由抽點和抽線的過程 以組成新的圖像。所謂抽點和抽線是指是從原圖像中抽取 一個個的點和一條條的線以組成新的圖像。 由於原圖像尺寸大於壓縮後圖像的尺寸，因此若從壓 縮後的圖像中的每一個點，去尋求在原圖像中的相應點， 應比從原圖像中的每個點向壓縮後圖像映射所作的計算量 要小。把根據壓縮後=圖被中像點的坐標，去尋求原圖像中 相應點坐標的過程稱為反算過程。 實際處理上，為了使圖像看起來不變形，對於一個點 來說，其垂直方向和水平方向的變形比例應該一樣，因此 我們便可以根據一個方向的壓縮比例來求取另一個方向的 壓縮比列。具體應用這個關係，體現在抽點和抽線的具體 過程.。 以「第1 B圖」所示水平二維景床後i化效果’我們處 理過程為對水平方向（X軸方向）採用非均勻抽線；對垂 直方向（Y軸方向）採用均勻等距抽點處理。所謂等距抽 點是指對於某一條垂直線來說，其壓縮後仍為一條垂直 線，壓縮過程即為等距抽點；而對水平方向抽線壓縮原 异ί :反算壓縮後垂直圖像線所對應ΐ]原圖像的垂直圖像 線，以此實現抽線。 以下為對應水平二維景深變化效果的水平反异袖線公 式推導過程。設在變換前後圖像左邊高度不變。如「第1 Α圖」及「第1Β圖」所示，變換前原圖的寬為w，高為Page 7 4 5 4 1 5 6 V. Description of the invention (5) The basic operation of the thumbnail is to make a new image through the process of drawing points and lines from the original image. The so-called points and lines refer to the extraction of dots and lines from the original image to form a new image. Since the size of the original image is larger than the size of the compressed image, if you look for the corresponding point in the original image from each point in the compressed image, it should be more compressed than from each point in the original image. The amount of calculations performed by the post-image mapping is small. The process of finding the coordinates of the corresponding points in the original image according to the coordinates of the image points in the compressed image is called the inverse calculation process. In actual processing, in order to make the image not appear distorted, the vertical and horizontal deformation ratios should be the same for a point, so we can get the compression ratio in the other direction according to the compression ratio in one direction. Column. The specific application of this relationship is reflected in the specific process of drawing points and lines. Take the effect of the horizontalization of the horizontal two-dimensional scene bed as shown in "Figure 1B". Our process is to use a non-uniform drawing for the horizontal direction (X-axis direction) and a uniform isometric drawing for the vertical direction (Y-axis direction). Point processing. The so-called equidistant extraction point refers to that for a vertical line, it is still a vertical line after compression, and the compression process is an equidistant extraction point; while the compression of the horizontal direction is the same as the original one. The image line corresponds to the vertical image line of the original image. The following is the derivation of the horizontal anti-sleeve line formula corresponding to the effect of the horizontal two-dimensional depth of field change. Set the left height of the image unchanged before and after the transformation. As shown in Figures 1A and 1B, the width of the original image before conversion is w and the height is

The process of the width of the image after w' is as follows: First, find the point with coordinate X on the original image in the Y direction. The compression ratio of is: (h-h ') xw can be calculated from the width w of the original image. Since tk / the compression ratio in the x direction and the compression ratio in the γ direction should be the same for a point, the Υ direction can be used. Instead of the compression ratio in the X direction, the compression ratio on the quadrature is multiplied in the X direction, and the width Ψ of the transformed graph is obtained. We can get: Γν r (h-h ') x., H + h' w Then, from This relationship of width changes derives that the point with the abscissa X 'in the transformed image is in the abscissa X of the original image, and has the following relationship: Γπ [h-h') y „{h — h ') f (c) dc = I [1-^ -——] ^ = c | 〇 ------° hw 2hw (/ 7- / 21) 2wh ...
