Embodiment Construction

[0014] Various exemplary embodiments, features, and aspects of the invention will be described in detail below with reference to the accompanying drawings.

[0015] figure 1 is a software configuration diagram of an object detection system providing an object detection function according to an embodiment of the present invention.

[0016] exist figure 1 , the object detection system includes an object detection function setting tool 101 , a network 102 , a network camera 103 and a client 120 . The object detection function setting tool 101 is a display control device that displays a video image corresponding to video data from the network camera 103 and provides a setting user interface for the purpose of object detection. The network 102 is a network capable of communication based on Internet Protocol (IP, Internet Protocol), such as a local area network (LAN) or the Internet (Internet).

[0017] The network camera 103 has a video camera function and an object detection fu...

Abstract

The invention provides a display control apparatus and a display control method. The display control apparatus, configured to output an event according to a result of comparison between a size of an object detected within an object detection region of a video image and a threshold value, includes a setting unit configured to set the object detection region, a determination unit configured to determine the threshold value based on a size of the set object detection region, and a display control unit configured to cause a detection region figure indicating the object detection region, and a detection size figure with a size corresponding to the determined threshold value to be superimposed on the video image.

Description

technical field [0001] The invention relates to a user interface for setting an object detection function for detecting objects within a video image. Background technique [0002] Conventionally, there is a surveillance system that utilizes an object detection function that detects and recognizes an object within a video image through image processing. For example, Japanese Patent Laid-Open No. 2000-125744 discusses a method of detecting a human object and comparing the human object with a small animal as a dangerous target by comparing the size (number of pixels) of the detected object with a preset threshold. Phase distinction. [0003] However, depending on the object that should be detected, it may sometimes be difficult to detect the object. [0004] For example, in the case of setting a standing height for detecting a human object, it may sometimes be necessary to consider complicated conversion of optical characteristics of a camera such as zoom magnification.
