Abstract: A method for associating event times or time periods with digital images in a collection for determining if a digital image is of interest, includes storing a collection of digital images each having an associated capture time; comparing the associated capture time in the collection with a special event time to determine if a digital image in the collection is of interest, wherein the comparing step includes calculation of a special event time associated with a special event based on the calendar time associated with the special event and using such information to perform the comparison step; and associating digital images of interest with the special event.

Abstract: Additional records are combined into a database of earlier-entered records clustered into existing events. A common chronology of a set of the existing events in the database and the additional records is determined based upon respective date-times of origination. Relative proportions of the earlier-entered and additional records in the database are ascertained. The following are identified in the chronology: existing events immediately preceding, concurrent with, and immediately succeeding additional records. When the relative proportions are beyond a predetermined reuse threshold, all of the records of the set and the additional records are reclustered into new events independent of the existing events. When the relative proportions are within the predetermined reuse threshold, only the identified records are reclustered with the additional records.
