Abstract
An image retrieval method and apparatus for extracting a desired frame as still image data from moving image data is provided, in which when a character search string is input, frames having the character search string are retrieved from moving image data including a plurality of frames, and if retrieved frames having the character search string in an equivalent position are consecutive for a predetermined amount, one of the consecutive frames is extracted as still image data.
Claims11
An image retrieval apparatus for extracting a frame of moving image data as still image data, comprising:
- a character string input unit configured to input a character string;
- a reception unit configured to specify a time period based on a user designation;
- a search unit configured to retrieve frames having the character string input by the character string input unit from moving image data including a plurality of frames;
- a detecting unit configured to detect a position of the character string input by the character string input unit in a frame of the moving image data;
- and
- an image extraction unit configured to extract, when the same position is detected by the detecting unit in each of a predetermined number of frames retrieved by the search unit which are consecutively displayed within the time period specified by the reception unit, one of the predetermined number of frames as still image data.
An image retrieval method for extracting a frame of moving image data as still image data, comprising:
- a character string input step of inputting a character string;
- a reception step of specifying a time period based on a user designation;
- a search step of retrieving frames having the character string input in the character string input step from moving image data including a plurality of frames;
- a detecting step of detecting a position of the character string input in the character string input step in the frames retrieved in the search step;
- and
- an image extraction step of extracting, when the same position is detected in the detecting step in each of a predetermined number of frames retrieved in the search step which are consecutively displayed within the time period specified in the reception step, one of the predetermined number of frames as still image data.
