Abstract
A redundant picture detecting device includes: a calculator for calculating difference information indicating a difference between a unit picture and a subsequent unit picture having an identical phase for each of the unit pictures; a multiplier for multiplying the difference information of a unit picture preceding an object unit picture by a predetermined first constant to produce a preceding difference information and for multiplying the difference information of a unit picture following the object unit picture by the first constant to produce a following difference information, the first constant being greater than zero and smaller than 1; and a judging unit for judging that the object unit picture is a redundant picture if the difference information of the object information is smaller than both of the preceding difference information and the following difference information.
