US Patent 11322114 Control of display directing content outside of a vehicle

Provided are a computer program products, systems, and methods for directing a system to control an intensity of light emanating from a display positioned within a vehicle to display content to be viewed from outside of the vehicle. The system determines whether the system is operating in a first mode or a second mode based on at least one vehicle operating condition. A light level within the vehicle is sampled more frequently during the second mode than during the first mode. A determination is made as to whether a threshold change in the sampled light level occurs when in the second mode, and an intensity of the display is adjusted in response to the occurrence of a threshold change.
