Abstract: A full display mirror assembly for a vehicle includes an electro-optic assembly containing an electro-optic medium, a display module, and at least one imager module configured to capture a blind spot. A processor and a memory including instructions that, when executed by the processor, cause the processor to, in response to a detection of an object in the blind spot, generate a first warning indicia in a first region of the full display mirror assembly. The processor is further caused to, in response to a detection that a vehicle containing the full display mirror assembly is turning or about to turn towards the blind spot with the object, generate a second warning indicia in a second region of the full display mirror assembly by enlarging the first region.
