Problems solved by technology

Although Figure 1D and Figure 1E The technical means of increasing the sampling frequency shown greatly reduces the amount of data that needs to be stored and calculated, but the picture quality it can bring is still far from the quality required in practice

Abstract

The invention discloses a drawing system and a pixel updating method thereof. The drawing system comprises a storage unit and a processing unit, wherein the storage unit is used for storing information; the information is used for defining a virtual area on a display picture; one pixel of the display picture and one part of the virtual area are overlapped, and the overlapped part corresponds to one type of color; the pixel defines a first edge, a second edge, a third edge and a fourth edge; the processing unit determines a first coverage rate, a second coverage rate, a third coverage rate and a fourth coverage rate of the virtual area on the first edge, the second edge, the third edge and the fourth edge; and the processing unit is also used for determining one display color of the pixel according to the color, the first coverage rate, the second coverage rate, the third coverage rate and the fourth coverage rate.

Description

technical field [0001] The present invention relates to a drawing system and a pixel updating method thereof; more particularly, the present invention relates to a drawing system adopting anti-aliasing technology and a pixel updating method thereof. Background technique [0002] In recent years, computer graphics technology has developed rapidly, and thus has been widely used in various fields, such as the film industry, the video game industry, and the like. However, due to hardware limitations, in computer graphics technology, high-resolution signals often have to be represented at low-resolution, and sometimes the graphics coordinates cannot be accurately calculated, resulting in concave-convex jagged edges of objects on the display screen. , this phenomenon is called aliasing. [0003] see Figure 1A , which is a schematic diagram of graph aliasing. Figure 1A Among them, a display screen 10 includes 16 pixels (pixels), and each pixel is represented by a square. The tr...
