ABSTRACT:
An electronic apparatus has a plurality of states, and includes a detection mechanism for detecting an external light and outputting a detection signal indicative of an intensity of the external light, a transition mechanism for making a state transition from a first state to a second state which is different from the first state and vice versa depending on the detection signal, and a varying mechanism for varying a light detection sensitivity of said detection mechanism depending on the detection signal when the state transition is made by said transition mechanism.
