Abstract

A monitoring system includes an imaging device and a control device. The control device includes a device communication section, a device controller, and device storage. The device controller includes an assignment section and a count section. The imaging device captures an image of an imaging area to generate captured image data indicating the captured image. The device controller acquires the captured image data from the imaging device through the device communication section. The assignment section assigns a plurality of candidate detection ranges to the captured image. The count section counts the number of occurrences of a specific event in each of the candidate detection ranges. The device storage stores therein the number of occurrences of the specific event in association with each of the candidate detection ranges.

First claim

What is claimed is:

1. A monitoring system comprising:
a data acquisition section configured to acquire captured image data indicating a captured image;
an assignment section configured to assign a plurality of candidate detection ranges to the captured image, the candidate detection ranges arranged in a matrix having a plurality of rows and a plurality of columns;
a count section configured to count the number of occurrences of a specific event in each of the candidate detection ranges;
storage configured to store therein the number of occurrences of the specific event in association with each of the candidate detection ranges;
a display controller configured to display the candidate detection ranges and the number of occurrences of the specific event in association with each other;
an input section configured to receive an instruction from a user;
a setting section configured to set any of the candidate detection ranges as a detection range based on the number of occurrences of the specific event and the instruction from the user; and
a detection section configured to detect the specific event in the set detection range out of the captured image based on the captured image data, wherein
the setting section specifies some candidate detection ranges to be included in the detection range among the candidate detection ranges based on the number of occurrences of the specific event and at least one predetermined threshold.

2. The monitoring system according to claim 1 , wherein
the display controller changes display of the number of occurrences of the specific event by time of day.

3. The monitoring system according to claim 1 , wherein
the display controller displays a boundary set for the detection range based on the number of occurrences of the specific event and at least one predetermined threshold.

4. The monitoring system according to claim 1 , wherein
the display controller displays the candidate detection ranges in different colors based on the number of occurrences of the specific event and at least one predetermined threshold.

5. The monitoring system according to claim 4 , wherein the display controller:
determines whether or not the number of occurrences of the specific event counted for each of the candidate detection ranges is displayable;
displays the number of occurrences of the specific event while displaying the candidate detection ranges in different colors upon determining that the number of occurrences of the specific event is displayable; and
displays only the candidate detection ranges in different colors each corresponding to one or more values of the number of occurrences of the specific event upon determining that the number of occurrences of the specific event is not displayable.

6. The monitoring system according to claim 1 , wherein
the count section counts the number of occurrences of the specific event by time of day, and
the setting section changes the specified candidate detection ranges that are included in the detection range among the candidate detection ranges by time of day.
