    Abstract: 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.

    Abstract: Apparatus and method for performing hierarchical coding without utilizing a delay circuit arranged separately from a memory for storing images. In the case where one second-layer pixel is formed from 2×2 first-layer pixels, three of the 2×2 first-layer pixels used to form the one second-layer pixel (excluding one final input pixel) are read out from a first-layer memory when the final input pixel is input. The three pixels read out are supplied to an adder which computes the sum thereof and supplies the sum value to an adder-subtracter. The adder-subtracter computes the sum of the sum value from the adder and the final input pixel so as to obtain the one second-layer pixel. Such second-layer pixel is supplied to a second-layer memory to be stored therein. The final input pixel is not stored in the first-layer memory.

    Abstract: A delay register section 31 holds SD pixels of a luminance signal and a classification section 33 decides a class, reads a coefficient corresponding to the decision result from a coefficient RAM section 40, and outputs the coefficient to a product-sum section 38. The product-sum section 38 captures the pixel data for 17 taps from the delay register section 31, converts the pixel data into seven taps, and outputs them to the product-sum section 38. The product-sum section 38 performs the product-sum operation of pixel data and coefficients and outputs the operation result as HD pixels. An interpolation pixel operation section 42 applies a simple interpolation processing different from the case of a luminance signal to the pixel data of a color signal component to generate HD pixels of a color signal. Thus, downsizing and cost reducing can be realized.
