    • A signal processing device and method, a program, and a recording medium configured so as to be able to detect 2-3 pulldown sequences, from various types of input, in a precise manner. A state estimation unit determines whether or not still positions between 10 fields to be handled fit the still positions of a 2-3 pulldown pattern configured of 12 fields including one sequence, using a difference evaluation value, a threshold value, and feature quantity, calculated by an evaluation value feature quantity calculating unit from the field of an 60I signal from an input terminal, and a field positioned temporally two fields earlier in the field memory, determination is made regarding whether or not a pattern regarding which determination has been made to fit has repeated transition in a transition order which the 2-3 pulldown pattern has for a predetermined number of times or more, and processing of an inverse 2-3 pd conversion unit is controlled according to the results of determination.
