Embodiment Construction

[0044] Hereinafter, the configuration of the video processing device 10 will be described with reference to the drawings. figure 1 is a block diagram showing the physical structure of the image processing device 10, figure 2 It is a block diagram showing the functional configuration of the video processing device 10 . The video processing device 10 extracts a representative image representing the video from a plurality of frame images constituting the video captured by the surveillance camera 100 to generate a thumbnail image. In addition, in this example, a monitoring camera is used as an example for description, but it is not limited to a monitoring camera and may be any other camera as long as it captures a moving image.

[0045] The image processing device 10 is a computer physically including a processor 12 , a storage device 14 connected to the processor 12 via a bus, a communication interface 18 (hereinafter simply referred to as “communication I / F 18 ”), and an input...

Abstract

A video processing device (10) according to the invention is provided with: a storage (28) that stores a video imaged by a camera and thumbnail images of the video; a score calculation unit (32) that calculates a representative score for each of a plurality of frame images constituting a video during a predetermined event; an image selection unit (34) that, on the basis of the calculated representative score, selects as a representative image a frame image representing the video during the event; and a thumbnail image generation unit (38) that generates and causes a thumbnail image of the representative image to be stored in the storage (28), wherein the score calculation unit (32) calculates a blur amount for each of the plurality of frame images constituting the video during the event and calculates the representative score at least on the basis of the blur amount.

Description

technical field [0001] This specification discloses a video processing device and a video processing method for extracting a representative image representing video content from video captured by a camera. Background technique [0002] Conventionally, an image processing device is widely known, which extracts a representative image representing the content of the video from a plurality of frame images constituting the video in order to roughly grasp the content of the video, and generates a thumbnail based on the representative image. image. As a method of extracting the above-mentioned representative image, for example, a technique of extracting frame images every fixed period as a representative image is considered. However, in the method of only periodically extracting frame images, there is a possibility that an image that fully expresses video contents cannot be obtained. [0003] Then, a technique has been proposed that partially extracts a representative image based...
