Patent ID: 7705913

Claim:
A method for film mode detection, comprising the steps of: (A) gathering a plurality of statistics from a plurality of fields in a video signal using a circuit; (B) detecting if said fields are in a 3:2 pull-down pattern to control a plurality of first flags based on said statistics; (C) detecting if said fields contain moving interlaced text to control a second flag based on both (i) said statistics and (ii) a repeat-field flag of said first flags that indicates repeating consecutive same polarity fields; and (D) deciding among a plurality of inverse telecine processes to de-interlace said fields based on all of (i) a 3:2 mode flag of said first flags, (ii) a 3:2 direction flag of said first flags and (iii) said second flag, wherein said 3:2 direction flag distinguishes between (a) both a current field and a next field originating from a frame and (b) both said current field and a previous field originating from said frame.
