摘要： A camera system and a method for zooming the camera system is disclosed. The method generally includes the steps of (A) generating an electronic image by sensing an optical image received by the camera, the sensing including electronic cropping to a window size to establish an initial resolution for the electronic image, (B) generating a final image by decimating the electronic image by a decimation factor to a final resolution smaller than the initial resolution and (C) changing a zoom factor for the final image by adjusting both of the decimation factor and the window size.

摘要： A method is provided for transcoding, i.e., decoding, and re-encoding, a previously encoded video signal, to a second encoded representation. A number k>1 of previously encoded pictures of the previously encoded video signal are received in a buffer. Each of the k previously encoded pictures in the buffer is scanned to gather information on each of the k previously encoded pictures. An encoding parameter is allocated to a first one of the k previously encoded pictures which precedes each other one of the k previously encoded pictures in encoded order of the previously encoded video signal. The encoding parameter is allocated based on the information gathered for each of the k previously encoded pictures. The first previously encoded picture is decoded to produce a decoded picture. The decoded picture is re-encoded to generate a re-encoded picture in a second encoded representation of the video signal. The re-encoding is performed in a fashion which depends on the encoding parameter allocated thereto. An apparatus is also disclosed for carrying out the method including a buffer, a scanner (for performing the scanning and allocating steps), a decoder and an encoder.

摘要： A method and system are provided for capturing and compressing an original uncompressed video signal which enables decoding and reversible reconstruction of a decompressed version of the original video signal. The system includes an input for receiving a signal indicating a special effect operation by which a first frame of a video signal is irreversibly transformed to a special effect frame. This is achieved by combining decompressed frame pixel data of the first frame with information comprising either pixel data of a second frame or a single scaling value to be used to scale plural pixels of a frame. The information indicates a special effect operation which can be performed on decompressed pixel data of the first frame to produce a special effect frame (e.g., the information can include a separate indicator specifying a specific operation or the information by its mere presence can indicate the special effect operation). The system also includes a processor for compressing pixel data of the first frame. The processor is also for constructing a bitstream containing the compressed pixel data of the first frame and the information. The bitstream is decompressible in a first manner to reproduce a decompressed video signal including the special effect frame, produced by performing the indicated special effect operation, in place of the first frame. The bitstream is also decompressible in a second manner to produce a decompressed version of the video signal with the first frame and without the special effect frame. The system and method according to this embodiment form a novel bitstream containing the compressed video frames and the information which can be stored on a storage medium. A system is also provided with a demultiplexer, decompressor and special effects generator for presenting the video signal with or without the special effect.
