Claim Text:
1. An image processing apparatus configured to remove noise from a frame group on a timeline, comprising: a judgment unit configured to identify changing points along the timeline, each of the changing points being a point where there is a large change between adjacent frames included in the frame group, and judge whether a pattern exists whereby the changing points appear at roughly a same interval along the timeline; a division unit configured to, in a case where it is judged that there is a pattern whereby the changing points appear at roughly the same interval, divide the frame group into a plurality of groupings along the timeline in accordance with the interval determined by said judgment unit; and a removal unit configured to remove noise from the frame group in units of the groupings, wherein the removal unit is configured to perform the noise removal for each grouping, using frames belonging to the grouping other than an exclusion frame, the exclusion frame being a frame commonly corresponding to a plurality of changing points that appear successively along the timeline, wherein the removal unit is configured to generate, for each grouping, Y number of representative frames representing X number of frames belonging to the grouping, where X≧2 and Y<X.
