Abstract: Provided is a method of detecting important information from a moving picture. The method includes: detecting first candidate areas that are presumed to include important information in a plurality of moving picture frames by using stop edge information, which is edge information overlapped at a same position throughout the plurality of moving picture frames, from among edge information in at least two received moving picture frames; determining second candidate areas by performing grouping on the stop edge information according to a position of the stop edge information in the first candidate areas; analyzing the second candidate areas determined in the at least two moving picture frames; and detecting important information areas from each of the at least two moving picture frames based on the analysis.
