Patent ID: 6996275

Claim:
An image control apparatus for performing control of image monitoring, comprising: encoding means for encoding an image from a monitoring camera; reduced image generation means for performing simplified decoding of an encoded image to generate a reduced image; feature amount extraction means for detecting an image event from the reduced image and extracting feature amounts therefrom; screen display control means for performing screen display control such that a listing of static images of the reduced image is displayed on a display, and a user is allowed to designate any of the static images to thereby set a detection event which is an event to be detected; detection dictionary-preparing means for measuring variance values from the feature amounts of the detection event to thereby prepare a detection dictionary containing detection parameters which are feature amounts having small variance values; event detection control means for calculating distances between the detection dictionary and the feature amounts to determine a detection range; and image-recording means for comparing the distances and a threshold value for recording images, and based on a result of the comparison, recoding monitored images.
