1. A method for automatically generating metadata for a user for a digital image, comprising:

  • obtaining user-definable aggregation rules of the user that includes at least one of;

    a rule indicating that “

    muggy”

    is specified when a plurality of ambient conditions is “

    warm” and



    very humid”

    ;

    a rule indicating that “

    sweltering”

    is specified when the plurality of ambient conditions is “

    hot” and



    humid”

    ;

    a rule indicating that “

    balmy”

    is specified when the plurality of ambient conditions is “

    mild”

    , “

    breezy”

    , and “

    partially humid”

    ;

    a rule indicating that “

    driving rain”

    is specified when the plurality of ambient conditions is “

    rainy” and



    windy”

    ;

    a rule indicating that “

    monsoon-like”

    is specified when the plurality of ambient conditions is “

    warm” and



    gusty” and



    rainy” and



    winds from the South to South-West”

    ;

    a rule indicating that “

    Sudden shower”

    is specified when the plurality of ambient conditions is “

    hot” and



    humid”

    transitioninq to “

    cooler” and



    rainy”

    ; and

    a rule indicating that “

    Clearing”

    is specified when the plurality of ambient conditions is “

    foggy”

    , “

    cold”

    , and “

    partly humid”

    transitioninq to “

    brightening”

    , “

    warming”

    , and with “

    falling humidity”

    ;

    determining a plurality of ambient conditions existing at a time related to a time of capture of the digital image and associated with a location of a subject of the digital image captured with a mobile image capture device even when the mobile image capture device is in a different location, wherein determining the plurality of ambient conditions includes determining variations of the ambient conditions over time by receiving readings of the ambient conditions at a plurality of times including at least one of a time before the time of capture, at the time of capture, and after the time of capture;

    aggregating and transforming data associated with the plurality of ambient conditions into at least one ambient trend descriptor based on the obtained user- definable aggregation rules wherein the aggregating includes aggregating the variations of the ambient conditions determined over the plurality of times;

    associating the ambient trend descriptor with the digital image as metadata; and

    enabling a user to search for the digital image based on the at least one ambient trend descriptor.
