Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/246062
Kind Code:
A1
Abstract:
This image processing device (10) comprises an image processing unit (110), a risk information generation unit (120), and a control unit (160). The image processing unit (110) acquires and processes an image generated by an image pickup device (20), that is, an image including a plurality of persons. As an example, the image processing unit (110) uses at least some of the plurality of persons as a reference person to calculate a distance (first distance) between the person and the closest other person. The risk information generation unit (120) uses the first distance to calculate a proximity index that is an index related to proximity states of the plurality of persons in a target area to be photographed by the image pickup device (20). When the proximity index satisfies criteria, the control unit (160) performs a predetermined control on a to-be-controlled device (30).
