Filed:

Oct 21, 1994

Appl. No.:

8/327530

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H04N 514

US Classification:

348 97

Abstract:

A video encoder control system and method are disclosed for controlling a video encoder using a processor having a multiple field delay circuit for delaying input video data by a predetermined number of frames, and a statistics generator for generating statistics from the video data to control the encoder. The statistics generator calculates a sum of absolute values of field differences between pixels, with the sum used for detecting a redundant field, for generating a film flag, and for controlling the encoder using the film flag. The statistics generator calculates averages of blocks of pixels, and a fade detector uses the averages for detecting fades between successive frames to generate a fade flag to control the encoding. The rate controller responds to the statistics to change the resolution of the encoding of successive frames. The processor outputs the film flags, scene change flags, and fade flags to the rate controller to control the encoding of the delayed video data.

US Classification:

358136

Abstract:

A decoder for a modified and improved MPEG signal syntax includes a subtractor responsive to an input signal, a frame buffer responsive to the subtractor, a motion compensator responsive to the buffer and to applied motion vector signals, and a multiplier responsive to frame leak signals and to a modified prediction signal for developing an output signal applied to the subtractor. Furthermore, the decoder includes a processor responsive to the motion compensator and to applied adaptive macroblock leak signals for developing the modified prediction signal. The processor comprises a transform circuit responsive to the motion compensator, a gating template responsive to the transform circuit and the adaptive macroblock leak signals, and an inverse transform circuit responsive to the gating template. The transform circuit operates on 2. times. 2 blocks of pixels to form 2. times.

Abstract:

Systems, structures, devices and methods for lensless compressive image acquisition are disclosed herein with which images may be obtained from a single detection element while performing fewer times than a number of pixels associated with the image. Advantageously such systems, structures, devices and methods may be adapted to acquiring images at wavelengths that are difficult or impossible with contemporary CCD or CMOS imagers.
