According to various embodiments disclosed herein, a lens assembly and/or an electronic device including the same may include at least four lenses which are sequentially arranged along an optical axis from an object side to a sensor side, and a tunable lens disposed between two lenses selected from among the at least four lenses and configured such that power or curvature thereof can be changed, wherein the lens assembly may satisfy Conditional Expression 1 below:1.0=<(tun_max)/(tot_min)=<3.0  [Conditional Expression 1]

Lens assembly and electronic device including the same

According to an embodiment of the disclosure, an electronic device may include a lens assembly including a first lens group having positive refractive power and a second lens group having negative refractive power and an image sensor configured to output an image signal based on light transmitted through the first lens group and the second lens group. A second distance between the first lens group and the second lens group and a third distance between the lens assembly and the image sensor may be configured to be changed based on a first distance between a subject and the electronic device.

Electronic device including lens assembly

A user terminal comprising a communication interface and a processor, transmits a user authentication request to an account management server so as to perform authentication in association with a user account; when a request to access an external server is received, transmits the request to access the external server to the account management server when first one-time password (OTP) information and second OTP information are received from the account management server, establishes a first communication channel with a relay server by using the first OTP information; establishes a second communication channel between the relay server and the external server by using the second OTP information; and communicates with the external server via the first communication channel and the second communication channel.

User terminal and control method of account management server for managing user account

According to certain embodiments, an electronic device comprises a window member; a display panel stacked on a rear surface of the window member; a lens assembly; an iris; and an image sensor including an image plane configured to form an electronic signal representing an image formed by the lens assembly, wherein the iris is fixed with respect to the image plane, wherein at least a portion of the iris is located on a same plane as at least a portion of the display panel, and the iris is located closer to an object-side than an object-side surface of a lens closest to the object-side of the lens assembly on an optical axis.
