AI Technical Summary

Technical Problem

Existing systems fail to effectively notify users of the presence of optical speed measurement devices, such as those using light-emitting devices, due to interference from ambient light and other factors leading to false alarms.

Method used

A system is provided with a light-receiving unit that selectively receives light of specific and different wavelengths, and a control unit that processes these signals to accurately notify the presence of a light-emitting device, using methods such as pulse counting, pulse width, and location-based triggers.

Benefits of technology

The system reduces false alarms by distinguishing between light from the light-emitting device and ambient light, ensuring accurate notification of the device's presence.

Abstract

To provide a technique for notifying a user of the presence of a light-emitting device emitting light of a specific wavelength.SOLUTION: An electronic device 10 provided herein is configured to detect a speed measurement device 30 emitting pulsed light Lout of a specific wavelength. The electronic device 10 comprises: a reception unit configured to receive light of a selected wavelength out of incident light; and a control unit configured to provide control to notify the presence of the speed measurement device 30 based on a first received light intensity as measured when the reception unit selects the light of the specific wavelength to receive the light and a second received light intensity as measured when the reception unit selects light of a wavelength different from the specific wavelength to receive the light.SELECTED DRAWING: Figure 1
