Claim Text:
1. An object detection system comprising: a memory, configured for storing at least a video sequence comprising a plurality of images; a processor, coupled to the memory, configured for: obtaining a first image corresponding to a first timepoint, a second image corresponding to a second timepoint, and a third image corresponding to a third timepoint of a video sequence from the storage unit, wherein a time difference between the first timepoint and the second timepoint is less than or equal to a time difference between the second timepoint and the third timepoint; searching for at least one feature from the first image; determining whether the at least one feature is within a near-distance detected region or a far-distance detected region; when the at least one feature is within the near-distance detected region, calculating a motion vector of each of the at least one feature according to the first image and the second image; when the at least one feature is within the far-distance detected region, calculating the motion vector of each of the at least one feature according to the third image and one of the first image and the second image; and confirming an existence of a moving object according to the motion vector of each of the at least one feature.
