Abstract:
1. An information signal processing apparatus for converting a first information signal containing multiple items of first informational data into a second information signal containing multiple items of second informational data, comprising: a first processing portion for selecting multiple items of the first informational data positioned in a periphery of a target position in said second information signal based on said first information signal and, based on said multiple items of the first informational data thus selected, detecting a class to which the second informational data of said target position in said second information signal belongs; and a second processing portion for selecting multiple items of the first informational data positioned in a periphery of the target position in said second information signal based on said first information signal and generating second informational data of the target position in said second information signal by performing an operation using said multiple items of the first informational data thus selected and coefficient data that corresponds to the class detected by said first processing portion, wherein said first processing portion and said second processing portion are respectively constituted of integrated circuits each having the same configuration, wherein each of said integrated circuits comprises:
