Abstract: An electronic device is disclosed. The electronic device of the present invention comprises a communication unit and a processor for receiving information on a refrigerator from the refrigerator through the communication unit, dividing an operation section of the refrigerator into an event section and a normal section on the basis of the received information, and determining whether the refrigerator is abnormal on the basis of a state of the refrigerator in the normal section or the event section among the received information. The event section includes a section from a time point when a door of the refrigerator is opened to a time point when the temperature of the refrigerator reaches a predetermined temperature after the door is closed, and the normal section includes a section from a time point when the temperature of the refrigerator reaches the predetermined temperature to a time point before the door is opened.

Abstract: Provided is a time of flight (ToF) sensor and a method for controlling the ToF sensor. The ToF sensor includes a first light emitter configured to output first light of a first pattern, a second light emitter configured to output second light of a second pattern, an image sensor including a plurality of pixels, and at least one processor configured to control the first light emitter and the second light emitter to sequentially output the first light and the second light, obtain, based on the output first light and second light being received through the image sensor by being reflected by a plurality of objects, a first image frame corresponding to the received first light and a second image frame corresponding to the received second light, and identify distances between the ToF sensor and the plurality of objects based on the first image frame and the second image frame.
