Patent ReferencesApparatus for improving video signal-to-noise ratio Bandwidth compressed transmission system Divisionally time-compressed subsample transmission and motion-compensated reproduction system for a high definition color television picture signal Method and apparatus for detecting the motion of image in a television signal Motion compensating field interpolation method using a hierarchically structured displacement estimator Signal processing unit for producing a selected one of signals predictive of original signals Patent #: 4802006 InventorsAssigneeApplicationNo. 314088 filed on 02/23/1989US Classes:348/415.1, Including temporal prediction (e.g., frame difference)348/424.1, Sub-Nyquist sampling386/50InterpolationExaminersPrimary: Peng, John K.Attorney, Agent or FirmInternational ClassesH04N 007/12H04N 007/18 H04N 009/88 H04N 005/94 AbstractWhen the receiving system for a band-compression image signal receives a dropout signal representing a dropout portion of an image signal, an output of the third delay circuit of the temporal filter for motion detection processing, that is, motion information of an image signal, which precedes by one field, and a dropout signal activate the signal selection control circuit to produce an output signal for controlling the operation of the signal selection circuit, so that an output signal of the first delay circuit is selected for a static portion of an image, and an output signal of the dropout compensation circuit is selected for a moving portion of an image, so as to effect compensation control of the dropout portion of an image signal, thereby preventing deterioration of the quality of an image.Other References
