Abstract
A method for identifying events in a scene captured by a motion video camera comprises two identification processes, a temporary identification process and a long-term identification process. The temporary process includes: analyzing pixel data from captured image frames and identifying events; registering camera processing data relating to each image frame subjected to the identification of events; and adjusting weights belonging to an event identifying operation, wherein the weights are adjusted for achieving high correlation between the result from the event identifying operation and the result from the identification based on analysis of pixels from captured image frames of the captured scene. The long-term identification process includes: identifying events in the captured scene by inputting registered camera processing data to the event identifying operation. The temporary identification process is then executed during a predetermined time period and the long-term identification process is executed after the predetermined initial time has expired.
