Patent ID: 8054340

Claim:
An image information management system comprising: an imaging device and an image information storage device connected to said imaging device through a network, said imaging device including: a trigger event detecting section which detects an occurrence of a trigger event; a photographing section which photographs images continuously; an image memory section which stores images photographed within a first predetermined time period before current time, and when the occurrence of a trigger event is detected by said trigger event detecting section, maintains the images photographed within the first predetermined time period before the trigger event occurs and stores images photographed by said photographing section within a second predetermined time period after the trigger event occurs; a first time stamp section which, when the occurrence of a trigger event is detected by said trigger event detecting section, asks a time stamp processing device connected through the network for time stamp processing of a compressed frame at trigger created by space compression of a latest frame of the images stored in said image memory section at the occurrence of the trigger event so as to obtain a time stamp of a time stamp result; an image file creating section that, when the occurrence of a trigger event is detected by said trigger event detecting section, awaits until the second predetermined time period lapses, and then creates an image file having a series of compressed frames created by space compression of the respective frames of the images stored in said image memory section; and a second time stamp section which asks said time stamp processing device connected through the network for time stamp processing of the image file created by said image file creating section so as to obtain a time stamp of a time stamp result; and said image information storage device including: an image information memory section which obtains the image file created by said image file creating section from said imaging device and stores the image file, key information associated with the image and the time stamps obtained by said first time stamp section and said second time stamp section, the key information including information relating to timing of the occurrence of the trigger event.
