DATA RETRIEVAL DEVICE, METHOD OF CONTROLLING THE SAME, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To solve the problem that it is difficult to confirm data excluded by an input retrieval condition when retrieving data and also it is impossible to efficiently retrieve the data when the retrieval condition is ambiguous.

SOLUTION: The data retrieval device displays the progress of retrieval processing and allows interruption of the retrieval, to prevent retrieval efficiency from being reduced even when the retrieval condition is ambiguous. The data retrieval device retrieves video/still image data at a higher speed and efficiently.
