Patent number: 6970507Abstract: Past image point information is also considered as well as local neighboring image point information in the interpolation of a predicted picture for motion-compensated prediction of moving pictures with increased resolution. Motion-compensated image point information is used in the interpolation raster between the scanned values of the reference picture (s?(t?1)) for the predicted picture of increased resolution.Type: GrantFiled: October 23, 2000Date of Patent: November 29, 2005Assignee: Robert Bosch GmbHInventors: Hans-Georg Musmann, Thomas Wedi

Patent number: 4771331Abstract: A motion compensating field interpolation method which allows the interpolation of several fields between every two transmitted fields of a digital television sequence. Using the model of translatorily displaced objects, a hierarchically structured displacement estimator is applied to cope with relatively large displacements. It provides a displacement vector with integer components for each picture element of the fields to be interpolated. A change detector is used to assure zero displacement vectors in unchanged areas. A two-coefficient spatio-temporal filter interpolates each picture element of the fields to be interpolated.Type: GrantFiled: March 6, 1987Date of Patent: September 13, 1988Assignee: ANT Nachrichtentechnik GmbHInventors: Matthias Bierling, Robert Thoma, Hans-Georg Musmann

Patent number: 4651207Abstract: In order to effect motion adaptive interpolation of nontransmitted television image sequences, each based on at least two transmitted television image sequences, the transmitted sequences are received and segmentally divided into stationary and moving components, and the displacement of the moving components is determined by picture elements. These operations are carried out by electronically segmentally dividing each sequence into background regions which are to become visible and background regions which are to become hidden due to the movement of each moving component and deriving characteristic segment information having four possible values; deriving a set of filter coefficients from the character segment information and from information obtained as a result of determining displacement; and applying the filter coefficients to a motion adaptive interpolation filter for causing the filter to generate the nontransmitted image sequences.Type: GrantFiled: March 5, 1985Date of Patent: March 17, 1987Assignee: ANT Nachrichtentechnik GmbHInventors: Hans C.

Patent number: 4630114Abstract: In a method and apparatus for determining, in a system having a transmitting end and a receiving end, displacements of image features occurring between successively transmitted image sequences, by the operations of: determining, at the receiving end, peak values of pixel correlation between successively transmitted image sequences; deriving representations of estimated displacement values from the peak values of pixel correlation; and producing representations of optimized displacement values by a recursion operation which includes recursively deriving a correction value and adding the correction value to an existing estimated displacement value to form a new estimated value, the correction value is derived by performing a mathematical division operation in which the dividend is a selected function of pixel values in successive image sequences and the divisor is proportional to the average of a first value resulting from crosscorrelation of successively transmitted image sequences and a second value resultingType: GrantFiled: March 5, 1985Date of Patent: December 16, 1986Assignee: ANT Nachrichtentechnik GmbHInventors: Hans C.

Patent number: 4200886Abstract: A method for transmitting video signals by differential pulse code modulation employing an adjustable quantizer which can be switched between different quantizing characteristics, by deriving the control criterion for switching the quantizer from the quantized prediction errors based on picture elements adjacent the picture element being quantized, providing the quantizer with a large number of available quantizing representative levels and employing a selected number of those levels, less than the total available, for each quantizing characteristic, and, omitting those representative quantizing levels of the quantizer, for which the spacing between the representative levels is less than twice the associated maximum permissible quantizing error belonging to the respective quantized prediction errors and providing representative levels at the outer ends of the quantizing characteristic instead of the omitted levels.Type: GrantFiled: September 11, 1978Date of Patent: April 29, 1980Assignee: Licentia Patent-Verwaltungs-G.m.b.H.Inventors: Hans-Georg Musmann, Wolf-Dieter Erdmann
