A display is configured to be able to change brightness of the display. A water detector is configured to detect water. A communication unit is configured to be able to communicate with another electronic apparatus. At least one processor is configured to, when the at least one processor detects, using the water detector, that at least part of the electronic apparatus is located in the water and detects, using the communication unit, that the another electronic apparatus is not located in the water, brighten the display compared with that when the at least one processor detects, using the water detector, that the at least the part of the electronic apparatus is located in the water and at least part of the another electronic apparatus is located in the water. ## Claims ### Claim 1 An electronic apparatus, comprising: a display configured to be able to change brightness of the display; a water detection circuit configured to detect water; a communication circuit configured to be able to communicate with another electronic apparatus; at least one processor configured to, when the at least one processor detects, using the water detection circuit, that at least part of the electronic apparatus is located in the water and detects, using the communication circuit, that the another electronic apparatus is not located in the water, brighten the display compared with that when the at least one processor detects, using the water detection circuit, that the at least the part of the electronic apparatus is located in the water and detects, using the communication circuit, that at least part of the another electronic apparatus is located in the water; and a water depth acquisition circuit configured to obtain a water depth of the display, wherein when the display comprises a first part that is submerged in the water and a second part that is not submerged in the water, the at least one processor is configured to change the brightness of the first part but not the second part. ### Claim 2 (depends on 1) The electronic apparatus according to claim 1, wherein the communication circuit is configured to receive a signal from the another electronic apparatus attached near a head of a user. ### Claim 3 (depends on 1) The electronic apparatus according to claim 1, further comprising: an illuminance detection circuit configured to detect a surrounding brightness, wherein the at least one processor is configured to change the brightness of the display based on the surrounding brightness. ### Claim 4 (depends on 1) The electronic apparatus according to claim 1, further comprising: a memory configured to store information relating to a weather; and a position information acquisition circuit configured to obtain a position information, wherein the at least one processor is configured to change the brightness of the display based on the information relating to the weather and the position information. ### Claim 5 (depends on 4) The electronic apparatus according to claim 4, wherein the information relating to the weather includes a history of wind velocity in an area indicated by the position information. ### Claim 6 (depends on 1) The electronic apparatus according to claim 1, further comprising: a date and time acquisition circuit configured to obtain a current date and time; and a position information acquisition circuit configured to obtain a position information, wherein the at least one processor is configured to change the brightness of the display based on the date and time and the position information. ### Claim 7 (depends on 1) The electronic apparatus according to claim 1, wherein the at least one processor is configured to execute a predetermined processing when a first conditions, a second conditions, and a third condition are satisfied: the first condition indicates that the water detection circuit does not detect the water; the second condition indicates that the at least one processor detects, using the communication circuit, that the another electronic apparatus is located in the water; and the third condition indicates that the at least one processor detects, using the communication circuit, that a user is in a predetermined state. ### Claim 8 (depends on 7) The electronic apparatus according to claim 7, wherein the predetermined state comprises a state where a value which indicates a biological information of a user detected by the another electronic apparatus does not fall within a predetermined value. ### Claim 9 (depends on 7) The electronic apparatus according to claim 7, wherein the predetermined processing comprises a processing of giving notice outside that a user is in a dangerous state. ### Claim 10 A control method that is executed by an electronic apparatus comprising a display configured to change a brightness of the display, a water detection circuit configured to detect water, and a communication circuit configured to be able to communicate with another electronic apparatus, the control method comprising: detecting, using the water detection circuit, that at least part of the electronic apparatus is located in the water and detecting, using the communication circuit, that the another electronic apparatus is not located in the water; brightening the display compared with that when it is detected that the at least the part of the electronic apparatus is located in the water and detecting, using the communication circuit, at least part of the another electronic apparatus is located in the water; and determining a water depth of the display, wherein when the display comprises a first part that is submerged in the water and a second part that is not submerged in the water the brightness of the first part is changed but the brightness of the second part is not changed. ### Claim 11 A non-transitory computer readable recording medium that stores a control program for causing an electronic apparatus comprising a display configured to be able to change brightness of the display, a water detection circuit configured to detect water, and a communication circuit configured to be able to communicate with another electronic apparatus, to execute: detecting, using the water detection circuit, that at least part of the electronic apparatus is located in the water and detecting, using the communication circuit, that the another electronic apparatus is not located in the water; brightening the display compared with that when it is detected that the at least the part of the electronic apparatus is located in the water and detecting, using the communication circuit, at least part of the another electronic apparatus is located in the water; and determining a water depth of the display, wherein when the display comprises a first part that is submerged in the water and a second part that is not submerged in the water the brightness of the first part is changed but the brightness of the second part is not changed.
