摘要： A 525i (interlace) signal can be converted into a 1050i signal or a 525p (progressive) signal. A calculating circuit generates pixels of an output picture signal with a linear estimation expression of predictive taps received from a tap selecting circuit and a coefficient received from a coefficient memory. The coefficient memory stores coefficients pre-obtained for individual classes. A class is determined by combining a spatial class corresponding to spatial class taps received from a tap selecting circuit and motion class taps received from a tap selecting circuit. A line sequential converting circuit converts a scanning line structure of an output signal of the calculating circuit 34 and obtains an output picture signal. The output picture signal is designated with a conversion method selection signal. Information corresponding to the selection signal is loaded from an information memory bank to the coefficient memory and registers.

摘要： JPEG encoded data are entropy-decoded to quantized DCT coefficients which are sent to a prediction tap extraction circuit (41) and to a class tap extraction circuit (42). The prediction tap extraction circuit (41) and the class tap extraction circuit (42) extract what is needed from the quantized DCT coefficients to form prediction taps and class taps. A classification circuit (43) effects classification based on the class taps. A coefficient table storage unit (44) sends tap coefficients corresponding to the classes resulting from the classification to a sum of products circuit (45), which sum of products circuit (45) then effects linear predictive calculations, using the tap coefficients and the class taps, to generate decoded picture data.

摘要： In each of the memory cell arrays in the memory banks, a memory cell row corresponding to each of the word lines extending in a column direction of each of the memory cell arrays store pixel data of each pixel block of first and second rows set in a horizontal way in a search area within a search frame of picture signal. The pixel data of a predetermined pixel block is selectively captured into each of the data buffer through the sense amplifiers and the switches. Selector sequentially extracts pixel data as candidate blocks based on the pixel data of two pixel blocks held in each of the data buffers. The matching circuit matches the pixel data as the extracted candidate blocks against the pixel data as the input reference block using the block-matching process to obtain a motion vector relative to the reference block.

摘要： An NTSC signal is supplied to a first area extracting circuit and a second area extracting circuit. The first area extracting circuit extracts class taps from the NTSC signal. The second area extracting circuit extracts predictive taps from the NTSC signal. The first area extracting circuit extracts pixels in predetermined positions from same phase pixels as a considered pixel. Based on level differences between extracted pixels, a pattern detecting section performs a class categorization. A class code determining section generates class codes based on the result of the class categorization and supplies the generated class codes to a coefficient memory. The coefficient memory outputs pre-stored predictive coefficients based on the class codes to a predictive calculating section. The predictive calculating section performs a sum of product calculation of pixel data as predictive taps received from the first area extracting circuit and the predictive coefficients received from the second area extracting circuit and generates for example a component signal Y with the result of the sum of product calculation.

摘要： A simplified Y/C separation circuit in which, a plurality of luminance signals are calculated for the subject pixel based on an NTSC signal of the subject pixel and NTSC signals of pixels that are close to the subject pixel spatially or temporally. Correlations between the plurality of luminance signals are obtained in a difference circuit and a comparison circuit. In a classification circuit, classification is performed, that is, the subject pixel is classified as belonging to a certain class, based on the correlations between the plurality of luminance signals. Prediction coefficients corresponding to the class of the subject pixel are read out from a prediction coefficients memory section. The RGB luminance signals of the subject pixel are then determined by calculating prescribed linear first-order formulae.
