Patent ID: 8554057

Claim:
An information signal processing method, comprising the steps of: acquiring data from image/voice feature data in each predetermined section of a predetermined image/voice data signal and extra information associated with the image/voice data signal or from a predetermined recording medium having these data recorded therein to make first predetermined information signification processing of each predetermined section of the image/voice data signal on the basis of the acquired data; connecting together a plurality of the predetermined sections subjected to the first predetermined information signification processing to make second information signification processing of the connected predetermined sections and predetermined evaluation value processing of the result of the second predetermined information signification processing or predetermined evaluation value processing of one predetermined section based on the signal subjected to the first information signification processing; and setting a predetermined playback section or a predetermined point in time of playback on the basis of the signal subjected to the second information signification processing or to the evaluation value processing; wherein making second information signification processing includes performing time correction based on a time correction coefficient; and wherein the predetermined evaluation value processing includes calculating a detection ratio of each predetermined feature data; comparing the detection ratio with a detection ratio coefficient; performing a logical product calculation for each feature data; comparing the calculated evaluation values; and selecting the largest evaluation value.
