摘要： A device generates coefficient data of an estimating equation for converting a first information signal to a second information signal. The device performs decimation on a teacher signal to generate a student signal and acquires plural training data items from the teacher signal corresponding to the second information signal and the student signal corresponding to the first information signal. For each training data item, a similarity determination unit acquires the similarity of the student signal with respect to the first information signal corresponding to a second information signal at a position of interest. Coefficient seed data, which are coefficient data of a generation equation including the similarity as a parameter, are determined using the training data items and the similarity. A coefficient data computing unit determines, based on the generation equation, coefficient data of the estimating equation using the coefficient seed data and a similarity value indicating the highest similarity.

摘要： A pattern matching section compares reference taps supplied by one area extracting section with a reference tap component of a training pair pre-stored in a training-pair storing section, selects a training pair including a reference tap component having highest similarity to the reference taps, and supplies the selected training pair to a normal-equation generating section. Training pairs stored in the training-pair storing section include a SD signal and HD signal. A prediction-coefficient determining section obtains prediction coefficients by solving normal equations generated by the normal-equation generating section. A prediction calculating section produces a HD signal by applying the prediction coefficients to prediction taps extracted by another area extracting section.

摘要： A class configuration generation unit generates (n−1) number of class configurations each of which is comprised of i number of the already selected features plus a feature selected from the remaining (n−i) number of the features (both of n and i are integers). A class configuration selection unit selects an optimal class configuration from the (n−i) number of the class configurations using an arbitrary evaluation value. The features used in the class configuration selected by the selection unit are used as the already selected features in the generation unit. The operations by the generation unit and the selection unit are repeated with values of i sequentially varying from 0 to r−1, thereby generating a class configuration comprised of r number of the features.

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.
