Embodiment Construction

[0035] Detailed description of the preferred embodiment

[0036] To facilitate digital transmission of digital signals and enjoy the corresponding benefits, some form of signal compression is generally required. In order to achieve high compression when generating images, it is also important to maintain high image quality. Also, implementation computational efficiency for tiny hardware is desirable, which is important in many applications.

[0037] Before describing an embodiment of the invention in detail, it is to be understood that the invention is not limited to the details of construction and arrangement of components set forth in the following description or illustrated in the accompanying drawings. The invention is capable of other embodiments and of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein are for the purpose of description and should not be regarded as limiting.

Abstract

An apparatus and method of serializing frequency based image data in a digital cinema system is described. At least one group of data that may be represented as a 16X16 block of data is compiled. Alternatively, a frame of data is compiled. The group of data is divided into four groups, each which may be represented as an 8X8 blocks. Each of the four 8X8 blocks of data are serialized using zig-zag scanning vertical scanning, and / or horizontal scanning.

Description

[0001] This application is a divisional application of a Chinese patent application whose application date is June 13, 2002 and whose application number is No. 02815583.1 and the invention title is "Configurable Graphics Optimizer". Background of the invention [0002] I. Field of Invention [0003] The present invention relates to image processing and compression, and more particularly to a configurable graphics optimizer for compressed images. [0004] II. Description of related technologies [0005] Digital image processing has a prominent position in the field of digital signal processing. The importance of human vision has fueled great interest and progress within the field and discipline of digital image processing. Various improvements in image compression have been made in the field of transmission and reception of video signals, such as those used for projection films or movies. Many current and proposed video systems utilize digital encoding techniques. Aspects o...
