an operation detection unit configured to detect an operation performed on an operation unit; a display controller configured to instruct a display unit to perform display when the approach of the object is detected; and a controller configured to: enter a first state in which the approach detection unit is in an off state and does not detect approach of an object, the first state entered when a state in which (a) the approach detection unit has detected the approach of the object to the approach section and also (b) the operation unit has not been operated, continues for a first period of time, and enter a second state in which power consumption of the electronic apparatus is lower than that in the first state, when a state in which the operation unit has not been operated continues for a second period of time after the controller enters the first state. ### Claim 2 (depends on 1) The electronic apparatus according to claim 1, wherein the display unit is included in a finder which is viewable through a finder section. ### Claim 3 (depends on 1) The electronic apparatus according to claim 1, wherein the electronic apparatus enters the second state when a state in which the operation detection unit is not operated continues for the second period of time while approach of an object to the approach section is not detected, and wherein restoration from the second state is performed when approach of an object to the approach section is detected. ### Claim 4 (depends on 1) The electronic apparatus according to claim 1, wherein in a case where the approach detection unit detects approach of an object to the approach section and the controller enters the second state from a state other than the first state or the second state, the controller does not perform display in the display unit included in the finder which is viewable through the finder section and performs display in a display unit outside the finder section, and in a case where the approach detection unit does not detect approach of an object to the approach section and the controller enters the second state from a state other than the first state or the second state, the controller does not perform display in the display unit outside the finder section. ### Claim 5 (depends on 1) The electronic apparatus according to claim 1, further comprising: an imaging unit, wherein the imaging unit is activated in the first state and the imaging unit is not activated in the second state. ### Claim 6 (depends on 1) The electronic apparatus according to claim 1, wherein the electronic apparatus is powered off when a state in which the operation detection unit is not operated continues for the second period of time after the controller enters the second state. ### Claim 7 (depends on 1) The electronic apparatus according to claim 1, wherein in a case where the controller enters the second state after entering the first state, the controller does not perform restoration from the second state even when an object approaches the approach section, and in a case where the controller enters the second state but does not enter the first state, the controller performs the restoration from the second state when an object approaches the approach section. ### Claim 8 (depends on 1) The electronic apparatus according to claim 1, wherein the controller displays a guide indicating that the display unit included in the finder does not perform display before a predetermined time point in a case where the controller enters the first state while the display unit included in the finder performs display. ### Claim 9 (depends on 1) The electronic apparatus according to claim 1, wherein the controller causes the approach detection unit not to detect approach of an object in a case where a state in which the operation detection unit is not operated continues for the first period of time. ### Claim 10 (depends on 1) A computer readable recording medium storing programs that cause a computer to function as units included in the electronic apparatus set forth in claim 1. ### Claim 11 (depends on 1) The electronic apparatus according to claim 1, wherein, in the first state, the approach detection unit is in an off state and does not detect approach of an object. ### Claim 12 (depends on 1) The electronic apparatus according to claim 1, wherein the controller enters the first state in a case where a state in which an operation on the operation unit has not been detected continues for the first period of time, regardless of whether the approach detection unit has detected approach of an object to the approach section. ### Claim 13 A method for controlling an electronic apparatus, comprising: detecting, at an approach detection unit, approach of an object to an approach section; detecting an operation performed on an operation unit; instructing a display unit to perform display when the approach of the object is detected; and entering a first state in which the approach detection unit is in an off state and does not detect approach of an object, when a state in which (a) the approach detection unit has detected the approach of the object to the approach section and also (b) the operation detection unit has not been operated, continues for a first period of time.
