Abstract: A region prediction unit predicts the target region in the second image frame based on the target region detected in a first image frame and a time interval between the first and second image frames. The region prediction unit predicts the target region in the third image frame based on the target region detected in the second image frame and a time interval between the second and third image frames. A region determination unit determines, as an image-processing region, a region obtained by adding a margin to the target prediction region in the third image frame in accordance with an overlapping portion between the detected target region in the second image frame and the prediction region in the second image frame.

Abstract: A vehicle configured to so as to be able to be remotely driven transmits information about each vehicle to a vehicle control apparatus through a network. In the vehicle control apparatus, an analysis unit receives information about each vehicle. The analysis unit analyzes state information of each vehicle based on the received information about each vehicle. Each remote control unit performs at least one of remote monitoring or remote control for at least one of a plurality of vehicles. An assignment determination unit determines a correspondence relationship between the vehicle and the remote control unit based on the analyzed state information.

Abstract: Disclosed is a communication apparatus or the like that is capable of reliably reducing communication delay. A communication apparatus (1101) has a transmission unit (1102), which, in a first period, transmits trigger information via a communication network (1103) corresponding to communication resource allocation, then, transmits information using the allocated communication resource, said first period being from first timing at which information is transmitted via the communication network (1103) to a second timing at which a specific communication resource is allocated to a request for communication resources for transmitting the information.
