    摘要: An image compression apparatus has a separation section for performing processing for dividing image data into a plurality of data blocks, an orthogonal transformer for orthogonal-transforming each data block, a bit allocation table for storing data representing the number of bits allocated in accordance with the frequency component of the orthogonal-transformed data output from the orthogonal transformer, an arithmetic operation circuit for calculating an amplitude probability density function of an identical frequency component of the orthogonal-transformed image data for each pixel, and calculating a quantization limit band causing a mean square error to be minimized in acordance with the calculating amplitude probability density function and the bit-number data from the bit allocation table, and a band limit table for storing the quantization limit band data. A quantizing circuit quantizes the orthogonal-transformed block information from the orthogonal transformer in accordance with the data stored in the allocation table and the band limit table.

    摘要: In a band compression apparatus, an input signal is separated into high- and low-frequency components H and L by an LPF and an adder. The component H is in-frame-averaged by an in-frame average circuit. The component L is output as a signal S.sub.3 having a large energy via a field delay circuit and a switch circuit. An in-frame difference of the low-frequency component L is obtained by a field delay circuit and an adder. This in-frame differential signal S.sub.2 is added to an in-frame average signal S.sub.1 by an adder. A signal S.sub.4 having a small energy is obtained by this addition. In a band restoration apparatus the signals S.sub.3 and S.sub.4 are separated into signals of two fields by an adder and a switch circuit. A signal S.sub.5 consisting of the components L and H is obtained in one field. A signal S.sub.2 consisting of only the component L is obtained in the other field. The signal S.sub.5 is output via a switch circuit. The signal S.sub.2 is added to the signal S.sub.5 in an immediately preceding field by an adder. A signal S.sub.6 consisting of the components L and H is obtained by this addition. The signal S.sub.6 is output via the switch circuit at a timing delayed by one field with respect to the signal S.sub.5.

    摘要: When both a progressive scanning video signal (for example, telecine signal) and an interlace scanning signal are present, the telecine signal is processed with pulldown information. The interlace scanning signal is processed without the pulldown information. Thus, even if both a telecine signal and a conventional interlace scanning signal are present, the pulldown information can be effectively used.

    摘要: A first image signal for a screen wider than that obtained by a TV signal of an existing television system is converted to a multiplexed signal that can be reproduced with a receiver of the existing television system, and input to a selector. The selector divides the input signal into a center portion signal and upper and lower black bar portions signals of the screen. The multiplexed signal has a center portion signal as an image display portion and upper and lower black bar portion signals as non-image portions. A difference signal (first LD signal) is multiplexed on the upper and lower black bar portion signals. A rearranging unit, a 5-time expander, a double speed converter, a delay unit, and a selector reproduce the first LD signal from the upper and lower black bar portion signals. A delay unit and a double speed converter double-speed convert the center portion signal. A line interpolator and a selector generate a progressive scanning signal. A 5.fwdarw.6 converter expands the progressive scanning signal in the vertical direction. The first LD signal is added to the interpolated scanning line of the first field by an adder. An LD generator generates a second LD signal from the compensated progressive scanning signal in the same manner as on the transmission side. A line interpolator and a selector also generate a progressive scanning signal. The second LD signal is added to the interpolated scanning line of the second field by an adder.
