Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capture systems face challenges with inaccurate face recognition and the need for pre-registration of face images, which raises privacy concerns.
Innovation Solution
An image capture apparatus that includes an image capture unit, information obtaining units for location, direction, and distance of objects, and a calculating unit to identify objects with wireless devices by determining if their calculated location matches the device's location within a predetermined range, allowing for precise identification without pre-registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If face image recognition is used to identify individuals, then the system can determine whether a person is included in an image, but the accuracy of recognition is insufficient and pre-registration of face images is required which raises privacy concerns
Solution Approach 1:
The patent extracts the identification function from traditional face recognition and implements it through wireless device detection. Instead of recognizing facial features, the system detects wireless devices (smartphones, wearables) carried by individuals using wireless communication modules. This extraction eliminates the need for pre-registering face images while maintaining identification capability, as the wireless device acts as a portable identifier that automatically pairs with the image capture apparatus.
2Measurement precision
If wireless device location matching is used to identify objects, then the accuracy of object identification is enhanced, but the system complexity increases due to multiple information obtaining units and calculating units
Solution Approach 1:
The patent implements multi-functionality by integrating multiple information obtaining capabilities into unified modules. The wireless communication module simultaneously performs location detection, device identification, and communication functions. The image capture unit also serves dual purposes by capturing both visual images and providing spatial context for object location. This consolidation reduces the number of separate components needed while maintaining the sophisticated identification functionality.
Solution Approach 2:
The patent introduces wireless device location information as an intermediary element that bridges the gap between physical object detection and digital identification. Instead of directly analyzing complex visual features, the system uses wireless device location data as a mediator to infer object presence and identity. This intermediary approach simplifies the identification process by converting it into a location-matching problem rather than a complex pattern recognition task.

AI summary
A location obtaining unit obtains information on a location of the image capture apparatus during image; a direction obtaining unit obtains direction of an object in an image captured; a device information obtaining unit obtains information on a location of a wireless device that is included by an object during image capture; a distance obtaining unit obtains a distance of the object in the image captured from the image capture apparatus; an object location calculating unit calculates a location of the object based on the information on the location of the image capture apparatus, a direction of the object in the image, and the distance of the object from the image capture apparatus; and an object identifying unit identifies that the object is the object including the wireless device if the location of the object and the location of the wireless device are within a predetermined range.
