摘要： A motion estimation system for finding motion vectors between first and second images selects first and second overlapping blocks of pixels from the first image. The motion estimation system then estimates motion between the first and second images to define respective motion vectors for the overlapping blocks. These motion vectors are assigned to respective first and second non-overlapping sub-blocks of pixels within the respective first and second overlapping blocks of pixels. The motion estimation system is advantageously used in a video de-interlacing system in which the sub-blocks are used to determine whether interpolated samples are generated using samples from both the first and second image fields or only from the first field.

摘要： A method and apparatus for reducing the maximum gain applied to a video signal during gamma correction are disclosed. A gamma exponent value, a black level, white level, and a desired maximum gain value are selected. A count of possible input signal values is determined. A modified black level is set equal to the desired black level. A gain limit value for the gamma correcting transfer function is calculated, and the smallest input signal for which the applied gain is less than or equal to the gain limit is determined. A black level correction factor is calculated. The modified black level is increased by the black level correction factor, and a determination is made whether the black level correction factor has decreased to less than a predetermined threshold value. The gamma correction function is recalculated and further black level corrections are added until the correction threshold is reached. The final transfer function increases linearly and has a gain equal to the gain limit value for video signal values near the desired black level. The gamma function increases non-linearly at a decreasing rate near the white level.

摘要： A method and apparatus for gamma-correcting digital video data and for adjusting the video signal to a desired pedestal (black) level, gain (white) level, and a gamma correction value includes an apparatus for calculating digital values corresponding to a video signal having the desired gamma correction, black level and white level and a memory for storing the digital values. Uncorrected input digital video signals address the memory and cause the corresponding digital values stored in the memory, which represent the corrected video signal, to be output. The invention can be implemented in both software or hardware.

摘要： A color video camera includes circuitry which generates a peaking signal that is applied to each of the color signals to enhance high-frequency components of the video signal relative to low-frequency components. The circuitry adds high-frequency components from the green video signal, as the peaking signal, at instants when the amplitudes of the green and red color signals are approximately equal. If there is a significant difference between the amplitudes of the red and green video signals, however, a combination of the high frequency components of both of these signals is used as the peaking signal. In one exemplary embodiment of the invention, the peaking signal includes in-band horizontal and vertical contour signals and out-of-band aperture correction signal.

摘要： Method and apparatus for producing a frozen television picture are disclosed. Successive fields of picture information are generated by an interpolator which is responsive to a video input signal. These successive fields are applied to the input of a first field store device. The video input signal is applied to the input of a second field store device so that the successive fields of the video input signal correspond in time to the successive fields generated by the interpolator. Lines from the respective field store devices are sequenced repetitively to form a video signal representing the frozen television picture. The interpolator generates fields which, when displayed with corresponding fields of the video input signal, minimizes motion-induced artifacts without unduly degrading vertical resolution.

摘要： An adder circuit is described for producing signals representative of the sum of large numbers of block-synchronized digital signals each of which may have any value within the range of quantizing levels represented. The adder circuit includes one or more binary counters coupled to count bits of the input signal having a particular significance. Counting takes place during an active interval such as a television field interval, and the counters are reset after each counting interval. The counter outputs are latched either before or after processing by addition of other counter outputs. The latched signal represents the sum of the values of the words in one sync block.

摘要： Horizontal and vertical registration errors in a color television camera are automatically error corrected by detecting registration errors in live scenes. Each error is associated with the preselected region of the raster in which it was detected. The errors are separately collected for each region. An error waveform is generated from collected error values. The past history of registration errors is also used. A correction waveform is generated to correct the registration error by minimizing the error waveform. This automatic registration system is microprocessor controlled.

摘要： An apparatus is provided for processing the output signals of a charge transfer device having at least one row of photoelectric elements. The charge transfer device produces output signals with charge levels that are provided to a shift register having a plurality of elements. The successive charge levels from each photoelectric element are provided to respective shift register elements, and the charge levels are transferred within the shift register to a readout terminal. Some of the charge is retained by each element as the charge is transferred. The retained charge is added to the next charge transferred into the element. This adding of residual charges averages the charges transferred, producing undesirable noise. A sample and hold device removes sampling artifacts inherent in the signal provided by the CCD, to produce a signal representing successive image pixel values. A peaking filter emphasizes high frequency components relative to low frequency components, to compensate for low pass filtering effects which may occur in the CCD.
