Reflection controllable view mirror device for motor vehicle or the like

摘要

A reflection controllable view mirror device having an electro-optical assembly which changes its optical transmittance to vary quantity of light passing therethrough in accordance with the magnitude of the applied voltage, a control circuit to control the transmittance at a value so as to ensure predetermined uniform reflection under circumstances permitting transmittance to deviate from inherent one because of deterioration or the like. Another control circuit is provided to control to ensure the inherent transmittance for predetermined reflection under the same circumstances.
