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 a system installed in a vehicle to conduct control for generating an alert in response to reception of laser light for measuring a vehicle speed. The electronic device 10 comprises: a light reception unit configured to selectively receive light of a specific wavelength contained in incident light, and output a signal corresponding to received light intensity; and a control unit configured to conduct first notification control to notify of the presence of a light-emitting device emitting the light of the specific wavelength based on the signal outputted by the light reception unit.SELECTED DRAWING: Figure 1 【課題】特定波長の光を発する発光装置の存在をユーザに報知するための技術を提供する。【解決手段】電子機器１０は、車両の速度を測定するためのレーザー光の受光に応じて警報を発する制御を行うため、車両に設けられるシステムである。電子機器１０は、入射した光のうち特定波長の光を選択して受光し、受光量に応じた信号を出力する受光部と、受光部が出力した信号に基づいて、特定波長の光を発する発光装置の存在を報知する第１報知制御を行う制御部と、を有する。【選択図】図１
