1. An operating method of a vehicle lighting device, the operating method comprising:
an observation operation in which information on a driving environment of a vehicle is observed with an observation unit;
a selecting operation in which a controller receives the information and selects image data regarding a visual image based on the information; and
a control operation in which the controller controls a light output unit to output light for displaying the visual image based on the image data, the control operation comprising a sorting operation in which the controller sorts a target as a reference for recognizing the light,
wherein, in the sorting operation, the controller sorts a driver as the target, but when at least one pedestrian is located within a predetermined distance from the vehicle, the controller sorts the pedestrian, instead of the driver, as the target;
the control operation further comprising, for the pedestrian:
a determining operation in which the controller determines a direction in which the pedestrian looks at the light;
a setting operation in which the controller sets a vanishing point at a point spaced apart from the pedestrian by a second predetermined distance in the direction; and
an adjusting operation in which the controller adjusts the light output unit so that the visual image is projected in perspective from the pedestrian toward the vanishing point.
