Description

Light emission control device and method, light emission device, vehicle, and storage medium Technical Field The present disclosure relates to a light emission control device, a light emission device, a vehicle, a light emission control method, and a non-transitory storage medium that control a light emitting portion provided in a vehicle. Background For example, japanese patent application laid-open No. 2015-006830 discloses an information display device that changes a light emission pattern of a plurality of light sources provided side by side along a boundary edge between a front windshield and an instrument panel based on various information such as driving information of a vehicle and surrounding information. In the case where the occupant is notified of information based on the light emission of the light emitting portion, there is room for improvement in order to enhance the recognition effect. Disclosure of Invention The present disclosure provides a light emission control device, a light emission device, a vehicle, a light emission control method, and a non-transitory storage medium that are capable of improving recognition effects in the case where information is notified to an occupant of the vehicle. The light emission control device according to the first aspect includes an object acquisition unit that acquires information on an object around a vehicle, and a control unit that controls, when the object is present, a plurality of light emission units provided in the vehicle to emit light in a coordinated manner. The light emission control device according to the first aspect is configured such that, when the object acquisition unit acquires information on an object existing in the vicinity of the vehicle, the control unit causes the plurality of light emission units to emit light in a linked manner. Therefore, the recognition effect for the occupant is higher than the case where only the plurality of light emitting portions are caused to emit light. That is, according to the light emission control device, the recognition effect in the case where the information is notified to the occupant of the vehicle can be improved. In the light emission control device according to the second aspect, in the light emission control device according to the first aspect, the control unit controls the light emission of the plurality of light emitting units so as to continuously move between the light emitting units. In the light emission control device according to the second aspect, the control unit controls the light to continuously move between the light emitting units when the light emission of the plurality of light emitting units is linked. Therefore, according to the light emission control device, the line of sight of the occupant of the vehicle can be guided. A third aspect of the light emission control device is the light emission control device according to the first or second aspect, wherein the object acquisition unit further acquires a position of the object with respect to an occupant of the vehicle, and the control unit controls the light emission of the light emission unit to continuously move from or toward the position of the object when viewed from the occupant. According to the light emission control device of the third aspect, the light emission of the light emitting unit is moved from the position of the object, and the line of sight of the occupant of the vehicle is moved away from the object. Further, according to the light emission control device, the light emission of the light emitting portion can be moved toward the position of the object, so that the line of sight of the occupant of the vehicle can be directed toward the object. A fourth aspect of the light emission control device is the light emission control device according to any one of the first to third aspects, further comprising a visual field acquisition unit that acquires information on a central visual field of an occupant of the vehicle, wherein the control unit includes at least one of a start point and an end point of light emission of the light emitting unit that continuously moves within a range of the central visual field. In the light emission control device according to the fourth aspect, when the visual field acquisition unit acquires information about the central visual field of the occupant of the vehicle, control is performed such that at least one of the start point and the end point of light emission by the light emission unit is included in the range of the central visual field. Therefore, according to this light emission control device, since the optical flow from the start point to the end point is necessarily included in the central visual field of the occupant, the recognition effect can be further improved. In a fifth aspect of the light emission control device, in the fourth aspect of the light emission control device, the control unit determines the paths along which the plurality of light emitting uni
