Problems solved by technology

[0009] Here, the technique disclosed in Patent Document 1 is applied to moving image data, a person captured in each frame image included in the moving image data is recognized, and the person is estimated from the number of frame images in which a certain person is captured. Even if they come to the shooting place together when they have a relationship with each other, they may give a lower evaluation

no. 1 Embodiment approach

[0063] 1. Overall structure

[0064] First, an overview of the sorting system will be described.

[0065] figure 1 It is a diagram showing a sorting system to which the video analysis device 2 of the present invention is applied. A computer 2 that reads the program and functions as a video analysis device is connected to a data recording device 1 such as a wearable camera or a video camera through a USB cable or the like.

[0066] The data recording device 1 includes a camera and a microphone, and records video data captured by the camera and the microphone on a recording medium. And, the recorded video data is output to the video analysis device 2 .

[0067] The video analysis device 2 analyzes the dynamic image data input by the data recording device 1, and obtains indexes for analyzing and sorting the dynamic image data. Specifically, for each scene obtained by dividing the moving image data according to predetermined time intervals, the photographed subject is identifi...

no. 2 Embodiment approach

[0206] In Embodiment 1, moving image data captured by the data recording device 1 is used as the object of video analysis, but in this embodiment, a plurality of still image data (hereinafter referred to as "frame images") is used as the object of video analysis. Object. Therefore, in the present embodiment, the data recording device 1 is, for example, a digital camera (DSC) or the like.

[0207] 5. Structure of image analysis device 2a

[0208] Figure 31 It is a block diagram showing the functional configuration of the video analysis device 2a of this embodiment. The video analysis device 2a is configured to include a database unit 310a, a participant information generating unit 322a, a photographer information generating unit 324a, a photographer-participant evaluation value calculation unit 350a, a participant evaluation value calculation unit 360a, and an evaluation value calculation unit 360a. Value information storage unit 370a.

[0209] The database unit 310a store...

Abstract

A video analysis apparatus comprising an identification unit for identifying each of persons imaged in each scene, a scene evaluation value calculation unit for calculating a scene evaluation value of the scene in which at least one person is imaged, a scene selection unit for selecting the scene(s) in which the above imaged person among all imaged persons identified by the identification unit is present from all the scenes, and a person evaluation value calculation unit for calculating a person evaluation value by summing the scene evaluation values of the scenes selected by the scene selection unit with respect to the above imaged person.

Description

technical field [0001] The present invention relates to the analysis technology of image data, and in particular to the technology of obtaining indexes for classifying and sorting the image data by analyzing the image data. Background technique [0002] In recent years, with the digitization of video data, the storage capacity of video data has increased dramatically. Therefore, there is a need for a technique for classifying and organizing image data with less labor. [0003] Algorithm software that supports classification and sorting of still image data has conventionally been provided. Exif information is added to the still image data in JPEG format. The Exif information includes the shooting time and position information obtained by GPS (hereinafter referred to as GPS data). In the past algorithm software, some algorithm software includes Exif information. The information is used as an index for classification and collation. [0004] Also, as another classification me...
