An electronic mirror includes an electronic lens assembly, a light sensor, an ambient light sensor and a control circuit. The electronic lens assembly is configured to reflect a light at a reflectance rate in response to a reflectance value. The light sensor is configured to generate an intensity value by logarithmic sensing the light proximate the electronic lens assembly. The ambient light sensor is configured to generate an ambient intensity value by logarithmic sensing an ambient light. The control circuit is configured to generate the reflectance value in response to the ambient intensity value and the intensity value while in a mirror mode. The refection value adjusts the reflectance rate of the electronic lens assembly with a negative fractional power of the intensity value.
