摘要： A control apparatus (2000) computes a waiting time index value for each of a plurality of gates (20) for entering an area (10). The control apparatus (2000) detects, from among the plurality of gates (20), a first gate (20) and a second gate (20) of which relation between the waiting time index values satisfies a first criterion. Herein, the waiting time index value of the first gate (20) is greater than the waiting time index value of the second gate (20). The control apparatus (2000) causes a terminal (30) associated with the first gate (20) to output priority use information, which allows prioritized use of the second gate (20).

摘要： In a video decoding device, a quantization step size decoding unit calculates a quantization step size that controls a granularity of the inverse quantization by, based on an image prediction, selectively using a mean value of at least a quantization step size assigned to a leftwardly adjacent neighboring image block already decoded and a quantization step size assigned to a upwardly adjacent neighboring image block already decoded or a quantization step size assigned to an image block decoded immediately before.

摘要： To improve efficiency of road surveillance, a road surveillance system includes a detection unit 122 and a processing unit 134. The detection unit 122 detects a road state being a state of an object on a road by processing an image in which the road is captured. The processing unit 134 performs, when the road state satisfies a first criterion, any of notification processing of making a notification of the road state that satisfies the first criterion according to notification setting related to the notification, and change-related processing related to a change in the notification setting, based on whether a second criterion is satisfied. The second criterion is a criterion related to a determination result of whether the road state satisfies the first criterion.
