說明書

in which the person extraction unit executes processing to determine whether or not a person detected in a frame to be processed is similar to a person detected in a previously processed frame in outer appearance feature values by a predetermined level or more, and

the program causes the computer to further function as a unit that receives a user input to set the predetermined level in the processing.

18-16. The program described in 18,

in which the extraction unit is caused to function as a word string extraction unit that analyzes text data to be analyzed and extracts a word string whose appearance frequency in the text data to be analyzed satisfies a predetermined condition among word strings detected in the text data to be analyzed, and
