Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current monitoring systems in stores cannot accurately display activity maps restricted to specific customer attributes like age or gender without a dedicated analysis device, leading to increased costs and potential user errors due to low accuracy.
Innovation Solution
An image-capturing device, recording device, and video output control device that image and process video feeds to output activity maps restricted to specific attributes by integrating an imager, positional information acquirer, attribute information acquirer, and activity map generator, enabling accurate attribute-based activity mapping without a dedicated analysis device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a dedicated analysis device is installed to generate attribute-restricted activity maps, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the activity map generation function into the image-capturing device itself by integrating the activity information acquirer and activity map generator modules. This allows the device to perform attribute-restricted activity mapping locally without requiring a separate dedicated analysis device, thus reducing system complexity while maintaining measurement precision through the embedded processing capabilities.
Solution Approach 2:
The image-capturing device is designed with multi-functionality, serving both as a video capture device and as an activity analysis device. The controller executes various functions including video capture, person detection, attribute determination, and activity map generation, making the device universal and eliminating the need for dedicated separate analysis equipment.
2Device complexity
If attribute-restricted activity maps are generated without adequate video quality checking, then device complexity is reduced, but measurement precision deteriorates leading to user errors
Solution Approach 1:
The controller performs preliminary evaluation of video quality and appropriateness before executing the activity map generation process. This preliminary action ensures that attribute-restricted activity maps are only generated when the video quality is sufficient, preventing user errors while maintaining system simplicity by using a straightforward quality assessment mechanism.
Solution Approach 2:
The system incorporates feedback through the controller that continuously monitors video quality and provides feedback to the activity information acquirer and activity map generator. This feedback mechanism ensures that only appropriate videos are processed, maintaining measurement precision without requiring complex additional processing stages.

AI summary
A positional information acquirer acquires positional information for every person from a video, an attribute information acquirer acquires attribute information for every person from the video, and an activity information acquirer restricts activity information to an attribute designated by a user based on the attribute information and the positional information, and acquires the activity information of which the attribute is restricted. An activity map generator generates an activity map of which an attribute is restricted based on the activity information, and a video output outputs a video acquired by superimposing the activity map. A controller determines appropriateness indicating whether or not the video output from the imager is appropriate, enables a function of outputting the activity map of which the attribute is restricted, and disables the function of outputting the activity map of which the attribute is restricted where the video output from the imager does not have the appropriateness.
