Light emitting device, control method for light emitting device, and medium

A light emitting device that is disposed inside a vehicle and emits light toward an occupant compartment where an occupant is seated, the light emitting device comprising:

• a light emitting unit that has a plurality of light emission regions aligned along one direction;
• and
• a control unit that controls the light emitting unit,
• wherein the control unit controls at least one of a light emission intensity and a light emission color of the light emission region for each of the plurality of light emission regions,
• wherein the control unit is configured to control the plurality of light emission regions using at least one of first information related to an operation of the vehicle and second information related to an operation of an output unit configured to perform output toward the occupant compartment,
• wherein the first information comprises navigation information for guiding a movement direction of the vehicle, wherein the control unit controls the plurality of light emission regions using the navigation information,
• wherein the navigation information comprises point information indicating a position where the vehicle needs to make a U-turn, and
• wherein the control unit controls the plurality of light emission regions in accordance with a predetermined rule when a positional relationship between the vehicle and the position where the U-turn needs to be made satisfies a reference.
