DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to an image processing system and its method and to an electronic system having an image processing system. It relates particularly to the image processing technique used to perform the movement transformation and/or rotation transformation in a video entertainment system.
BACKGROUND ART
As more and more people have an interest in multimedia today, methods and systems are being developed in the field of hardware which will become the platform of multimedia. This type of hardware is designed to implement complex and sophisticated image processing in order to satisfy the needs of program software. Especially, in the video entertainment systems, the demand for image processing ability having more realistic and dramatic effects has been increased to satisfy the user's growing need.
The prior image processing technique is as follows. According to the prior art of the image processing system used in a video entertainment system, the background image where the surface of the land or the sea, the sky, or the space is displayed is combined with the foreground image where the character of the game is displayed, and the composite image is displayed on the monitor screen of the display. When a game player plays the game, the foreground image or background image is moved to show the motion of the character. That is, the foreground image is moved or rotated with the background image fixed or, conversely, the background image is moved or rotated with the foreground image fixed. The latter function is called the scroll function.
In addition to the scroll function described above, an image processing system has other functions such as the window function and the priority function. The following describes these functions.
The following is a brief description of the window function and the priority function. Recently, more and more data has to be displayed on one monitor screen. To meet this need, the window function has been introduced; it divides the screen into one or more transparent image areas, called windows, and displays different types of data in each window. Windows are normally overlapped with the background image or with other windows. And, among a plurality of overlapping windows, only one window is displayed on top of the others according to the specified priority. This priority is determined by the priority function. The priority function plays an important role in today's image processing technique; that is, it not only determines the priority when windows are displayed and displays windows but also deter mines the priority between the background image and the fore ground image or the priority among a plurality of foreground images of various types.
The following is a description of the scroll function. The scroll function moves the background image while keeping the foreground image, containing the character, near the center of the display screen. Moving the background image does not mean the transformation of image information (that is, the background image itself is not moved); the background image is a virtual static image stored in the image memory of the image processing system. More precisely, we can say that a display screen frame or a player's viewpoint simply moves around the whole background image stored in an image memory as a result of actual calculation. Strictly speaking, a display screen is a virtual screen set up for each circuit which performs movement transformation or rotation transformation. However, in the following discussion, a display screen may be thought of as the monitor screen of a display because it is the screen on which images are displayed.
There are two types of scroll screen formats: the cell format used on a home video entertainment system and the bit mapped format used on a personal computer. To display a cell format scroll screen on the display screen, a plurality of cell patterns, the same displayed as necessary, for example, each consisting of 8.times.8 pixels are combined and displayed on the display screen as background image
