INFORMATION PROCESSING DEVICE, CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/109879
Kind Code:
A1
Abstract:
In the present invention, a determination unit determines whether or not a first foreground area extracted from a first captured image shows a mobile object. A warning unit outputs a warning when it is determined that the first foreground area does not show a mobile object. A determination means determines that the first foreground area does not show a mobile object when it is determined that an object shown by the first foreground area is not moving, in both a first determination and a second determination. In the first determination, the determination means determines whether or not the object shown by the first foreground area is moving, by comparing, with the first foreground area, a second foreground area extracted from a second captured image that is generated earlier than the first captured image. In the second determination, the determination unit determines whether or not the object is moving at a time point before the time point when the first captured image is generated, on the basis of the information about the object at a time point before the time point when the first captured image is generated.
