Signal processing device and method, recording medium, and program

A signal processing method for adjusting levels of continuously arranged signals, said signal processing method characterized by comprising:

• a designation step of designating continuously arranged signals as a signal of attention one by one;
• a determination step of determining a predetermined number of signals preceding the signal of attention designated by way of the designation step, and a predetermined number of signals following the signal of attention, to be neighbouring signals;
• a weight average step of averaging by weight the signal of attention and the plurality of neighbouring signals;
• a flag setting step of calculating a difference in levels between the signal of attention and a neighbouring signal, judging whether or not the difference is larger than a predetermined threshold value, and raising flags for the neighbouring signal and a neighbouring signal which are arranged symmetrically with respect to the signal of attention, when the difference is judged to be larger than the predetermined threshold value;
• and
• a control step of controlling and causing a process in the weighted average step to average by weight, using the signal of attention instead of the neighbouring signal for which the flag is raised.
