INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD
First Claim
1. An information processing apparatus comprising:
- a background image storage unit configured to store a background image;
a periodic event storage unit configured to store conditions for the occurrence of a periodic event and information as to the time of the occurrence of the periodic event;
an image input unit configured to input an image;
an image comparison unit configured to compare the background image stored in the background image storage unit with an input image input from the image input unit to obtain a difference;
a periodic event collation unit configured to collate a change in the difference and time of the change with the conditions for the occurrence of the periodic event and the information as to the time of the occurrence of the periodic event stored in the periodic event storage unit in order to determine whether the change of the input image in state is the periodic or the non-periodic movement of an object; and
a selection unit configured to select, according to the result of a determination by the periodic event collation unit, any one of operations according to the periodic or the non-periodic movement of an object.

Abstract
An information processing apparatus and method for processing an input image by comparing a stored background image with the input image to obtain a difference, collating a change in the difference and time of the change with conditions for the occurrence of a periodic event and information as to the time of occurrence of the periodic event, which are previously stored in a storage unit, to determine whether the change in state of the input image is the periodic or a non-periodic movement of an object, and selecting, according to a result of the determination, any one of operations according to the periodic or the non-periodic movement of an object.
