摘要:
A printed audio format includes a printed encoding of an audio signal, and a plurality of spaced-apart and parallel rails. The printed encoding of the audio signal is located between the plurality of rails and each rail comprises at least one marker. The printed encoding comprises a first portion and a second portion, each portion comprises a plurality of code frames, and each frame represents a time segment of an audio signal. The first portion encodes a first time period of the audio signal and the second portion encodes a second time period of the audio signal. The second portion is encoded in reverse order with respect to the first portion so that the joining part is on the same end of both portions.

A digital still camera comprises an imaging system for capturing a single image of printed material containing a printed audio format; a processor for extracting encoded audio data from the image; a decoder for receiving and decoding the encoded audio data to an audio signal; and an audio output for outputting the audio signal as audio.

An optimized 3D graphics library for a computer having a 3D graphics board or its equivalent is provided. The library provides a number of groups of functions which are optimized to simplify common tasks while being small enough building blocks to be used for most applications. In particular, the library provides the following groups of functions: (a) screen/window initialization, (b) primitive operations, (c) primitive properties, (d) buffer management, (e) color management, (f) queries, and (g) texture management.
