Abstract
A coefficient data generating apparatus includes a coefficient data generator and an estimation predictive calculation circuit. The coefficient data generator generates for each class coefficient data for an estimation expression which is used to obtain horizontal and vertical resolution corresponding to parameters input from a remote control transmitter by a user. The coefficient data is stored in a coefficient data memory. The estimation predictive calculation circuit generates based on an estimation expression HD pixel data constituting an output picture signal by using other coefficient data read from the coefficient data memory, and SD pixel data of prediction taps. The coefficient data is generated by linearly adding pieces of coefficient-generating data, and the output picture signal can be obtained so as to corresponds to the input parameters. This makes it possible to freely control the resolution of a displayed picture.
