ABSTRACT:
A signal processing apparatus processes a signal which has a plurality of spectral sensitivity characteristics and in which the information amount of a signal related to at least one of the spectral sensitivity characteristics is larger than the information amount of any one of signals related to the other spectral sensitivity characteristics. A wavelet transform section resolves the signal of the spectral sensitivity characteristic having a large information amount into high- and low-frequency components. An R- and B-signal correlation coefficient calculating section calculates correlation coefficients between the low-frequency component derived and the signals of the spectral sensitivity characteristics having a small information amount. An R- and B-signal high-frequency creating section creates high-frequency components of the signals of the spectral sensitivity characteristics having a small information amount based on the correlation coefficients derived and the high-frequency component. An R- and B-signal inverse wavelet transform section synthesizes the high-frequency components thus derived and the signals of the spectral sensitivity characteristics having a small information amount to output an output signal with high definition.
