The display device includes a display screen. The touch sensor is configured to detect an operation on a display screen side of the display device. The account switching module is configured to switch a logged-in account from a second account which is lower than a first account to the first account when a detection result of the touch sensor corresponds to a pinch-in operation, and to switch the logged-in account from the first account to the second account when the detection result of the touch sensor corresponds to a pinch-out operation. The display controller is configured to control the display device so as to display an image on the display screen. ## Claims ### Claim 1 An electronic device comprising: a display device comprising a display screen; a touch sensor configured to detect an operation on a display screen side of the display device; an account switching module configured to switch a logged-in account from a second account which is lower than a first account to the first account when a detection result of the touch sensor corresponds to a pinch-in operation, and to switch the logged-in account from the first account to the second account when the detection result of the touch sensor corresponds to a pinch-out operation; and a display controller configured to control the display device so as to display an image on the display screen. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein the display controller is configured to control, when the logged-in account is switched from the second account to the first account in accordance with the pinch-in operation, the display device so as to reduce a size of at least a portion of an image displayed at a time when the second account is logged in. ### Claim 3 (depends on 1) The electronic device of claim 1, wherein the display controller is configured to control, when the logged-in account is switched from the first account to the second account in accordance with the pinch-out operation, the display device so as to enlarge a size of at least a portion of an image displayed at a time when the first account is logged in. ### Claim 4 (depends on 1) The electronic device of claim 1, further comprising: a detection position acquisition module configured to acquire a detection position of the pinch-in operation or the pinch-out operation; and an account selection module configured to select one of a plurality of accounts from positions of a plurality of images corresponding to the accounts, respectively, displayed on the display screen and from the detection position detected by the detection position acquisition module, wherein the account switching module is configured to switch the logged-in account to the one of the accounts selected by the account selection module. ### Claim 5 (depends on 1) The electronic device of claim 1, further comprising an account selection module configured to acquire stored data on a login history for each of a plurality of accounts, and to select one of the accounts with a large login count or along time period during which the account has been logged in, wherein the account switching module is configured to switch the logged-in account to the one of the accounts selected by the account selection module. ### Claim 6 (depends on 1) The electronic device of claim 1, further comprising: a data acquisition module configured to acquire image data or sound data; and a data comparison module configured to compare face image data acquired by the data acquisition module with face image data stored in association with an account ID or to compare voice sound data acquired by the data acquisition module with voice sound data stored in association with the account ID, to specify one of a plurality of accounts corresponding to the acquired face image data or the acquired voice sound data, wherein the account switching module switches the logged-in account to the one of the accounts specified by the data comparison module. ### Claim 7 (depends on 1) The electronic device of claim 1, wherein the account switching module is configured to switch the logged-in account when the pinch-in operation or the pinch-out operation is data detected in a specific area of the touch sensor. ### Claim 8 (depends on 1) The electronic device of claim 1, wherein the account switching module is configured to switch the logged-in account when the detection result on the touch sensor corresponds to the pinch-in operation or the pinch-out operation following a specific operation. ### Claim 9 The electronic device comprising: a display device comprising a display screen; a touch sensor configured to detect an operation on a display screen side of the display device; and a display controller configured to control the display device so as to switch an image displayed on the display screen from an image corresponding to first data to an image corresponding to at least one of a plurality of pieces of second data associated with the first data when a detection result of the touch sensor corresponds to a pinch-out operation, and to control the display device so as to switch the image displayed on the display screen from the image corresponding to the at least one of the pieces of the second data to the image corresponding to the first data. ### Claim 10 A computer program product having a non-transitory computer readable medium including programmed instructions for a controller of an electronic device comprising a display device comprising a display screen, a touch sensor configured to detect an operation on a display screen side of the display device, wherein the instructions, when executed by a computer, cause the computer to perform: switching a logged-in account from a second account which is lower than a first account to the first account when a detection result of the touch sensor corresponds to a pinch-in operation, and from the first account to the second account when the detection result of the touch sensor corresponds to a pinch-out operation; and controlling the display device so as to display an image on the display screen.
