Abstract
A signature device including a storage unit configured to store moving image data, and a processor configured to extract original metadata from moving image data for the image data of each of a plurality of images forming the moving image data, the original metadata including location data of the image data and identification data of the moving image data, to encode the image data of each of the images into still image data in accordance with an image format, to write the still image data into a first area, to write the original metadata extracted by the extractor into a second area, the first area and the second area being included in a storage area of a still image data file in which the still image data is filed, and to generate summary data for the still image data file.
Claims5
A system comprising:
- a storage unit configured to store moving image data, the storage unit being configured to store respective summary data of a still image data file in relation to location data of each of a plurality of frames in the moving image data, the still image data file including a first area and a second area, the first area being an area in which still image data encoded from image data in accordance with an image format is stored, the second area being an area in which data of location of the image data in the moving image data and identification data of the moving image data are stored;
- and
- a first processor coupled to the storage unit and configured to:
- extract data filed in the second area in the still image data file to be verified,
- search a group of summary data stored in the storage unit for summary data such that a combination of the identification data of the moving image data and the location data of the image data corresponds to the data extracted,
- generate summary data for the still image data file to be verified;
- make a decision whether the summary data searched for agrees with the summary data generated, and
- output the decision to display.
