Abstract: Provided are a device and a method which enable easy analysis and evaluation of work efficiency of a worker without burdensome tasks and easy determination of a worker's skill level by comparing the worker's work efficiency status with that of another worker or a past record of the same worker, wherein analytical information is produced by estimating the worker's joint positions based on a video; acquiring time series data on joint positions; determining work efficiency based on the time series data; acquiring a target range (part of a work process with low work efficiency); output an image of the target range overlaid on a graph of the time series data; and output a posture image of the worker overlaid on the video. The analytical information may include information on a working activity to be analyzed and information on a chosen model working activity with high work efficiency.

Abstract: A person's behavior monitoring device includes a processor for acquiring a captured image of each of a plurality of cameras, acquiring information relating to a person requiring special attention by analyzing the captured image, and generating a monitoring image including the information, in which the processor determines, for each of the cameras, whether or not a person detected from the captured image is a long-time stayer who stays for a long-time in a capturing area of one of the cameras based on a result of tracking the person, and superimposes and displays a person rectangle that enables identification of a degree of stay on the captured image in correspondence with a person corresponding to the long-time stayer.

Abstract: It is possible to acquire analysis information pertaining to a customer's commodity acquisition behavior with high accuracy by discriminating whether a subject of an action of reaching out to a display shelf area is a store employee or a customer. The personal behavior analysis device includes: an image analyzer that analyzes captured images around a display shelf area, detects a person staying in front of a display shelf area, and acquires analysis information pertaining to physical states of the person; an access action detector that detects an access action, based on the analysis information; a behavior determiner that determines whether or not the access action corresponds to a prescribed behavioral pattern based on access action occurrence circumstances; and an analysis information generator that selects the access action and generates analysis information pertaining to the access action occurrence circumstance.

Abstract: In order to enable, even when an increased number of workers become analysis targets, efficient analysis on work efficiency statuses of workers without putting a greater burden on an administrator to perform setting operations for the analysis, analytical information is produced by performing a joint position estimation based on respective frames of video recordings to estimate joint positions of a worker, performing a posture match determination based on results of the joint position estimation to determine whether or not to achieve a posture match between a posture of the worker in each frame of the video recordings and a predetermined reference body posture, and measuring, based on results of the posture match determination, a working time and a presence time of the worker used as analytical information on a work efficiency status of the worker.

Abstract: An image search device includes a cluster processor that performs clustering with respect to a collection of the person images, and selects a key cluster that has a largest number of images for each staying person; a search condition acquirer that acquires information related to the search target person as a search condition; a person collator that acquires, based on the search condition and the feature information of each staying person, a degree of similarity with the search target person for each staying person; an output condition setter that sets, according to the operation input by the user, an output condition related to an extraction range of a search result; and an output image extractor that extracts, from the key cluster of a staying person with a higher degree of similarity, a plurality of the person images as a search result according to the output condition.
