The present invention relates to a mobile terminal comprising a liquid lens including: a side wall part; a first and a second glass layer which cover one surface and the other surface of the side wall part, respectively, to form a receiving part; a plurality of electrode modules, each of which is positioned on the side wall part and includes a first and a second electrode; an insulation layer covering the first electrode; a nonpolar liquid filled in the receiving part; and a polar liquid which is separated from the polar liquid in layers, is filled in the receiving part, and is in contact with the second electrode, wherein a boundary surface between the nonpolar liquid and the polar liquid changes into a shape protruding toward the polar liquid as a voltage applied to the electrode modules increases, and a control part differently controls at least a part of the voltage applied to the plurality of electrode modules to adjust a position of a protrusion of the boundary surface.

Optical device and mobile terminal

In order to effectively perform auto focusing and an OIS function, provided is an optical device in a first diopter state, the optical device comprising: a liquid lens having a variable diopter; a memory in which regions of interest (ROIs) according to the variable diopter are recorded; a lens control unit for retrieving a first ROI corresponding to the first diopter from the memory and configuring the first ROI; and a diopter operating unit for auto-focusing the first ROI to change the liquid lens to have a second diopter.

Optical device

Provided is an optical device for reducing the time for auto focusing (AF) performed by a contrast detection system, the optical device comprises a liquid lens having a curvature that varies on the basis of an applied electrical signal and the liquid lens may be auto-focused at one time from the current curvature (i.e., the first curvature state, p) to a target curvature corresponding to a distance to the subject (i.e., a second curvature state) based on the FV slope ratio.

Optical device and mobile terminal comprising same

The present invention is to provide a mobile terminal and a method for controlling the same that may secure an appropriate amount of light for a subject and minimize a shadow of the subject even when capturing an image in a close-up manner using a camera embedded in the mobile terminal. One aspect of the present disclosure proposes a mobile terminal including a rear cover having an opening defined therein, a camera disposed to be optically exposed to the outside through the opening, a flash surrounding the camera, wherein the flash is disposed to be optically exposed to outside through the opening, a support frame surrounding the flash and being attached to one surface of the rear cover corresponding to a periphery of the opening while being externally exposed to outside through the opening, and a cover glass attached to the support frame to cover the camera and the flash.

Mobile terminal and method for controlling the same

A method of controlling a mobile terminal includes the steps of injecting a laser signal to a direction at which a camera is facing, receiving a reflected laser signal corresponding to the injected laser signal returned in a manner of being reflected to a subject, calculating a distance from the subject using a difference between time of injecting the laser signal and time of receiving the reflected laser signal, calculating standard illuminance of a flash based on the distance from the subject, injecting light by controlling the flash according to the standard illuminance and storing a first image including the subject using a camera module. According to the method, since it is able to obtain an image of which a whole screen is maintained by a reasonable brightness, a subject and a background can be included in an image.

Method for controlling mobile terminal and mobile terminal

A mobile terminal including a wireless communication unit configured to perform wireless communication; a display unit; a memory configured to store a plurality of images; and a controller configured to receive a command for displaying a focus-based thumbnail list, and display the focus-based thumbnail list to include at least one thumbnail corresponding to an image stored in a memory with focus information, said focus information indicating a focal region focused in the image.

Mobile terminal and controlling method thereof

A mobile terminal including a camera configured to photograph a plurality of images; a touchscreen configured to display one of the plurality of the photographed images or a first synthetic image created from synthesizing at least two of the plurality of the photographed images together as a representative image; and a controller configured to receive a first touch input applied while the representative image is displayed, extract an image having a best resolution for an object or region selected by the first touch input from the plurality of the photographed images, and display the extracted image via the touchscreen.

A mobile terminal and a method for composing 3D images thereof are disclosed. The method for composing 3D images of a mobile terminal includes: selecting a background image as a reference from an image buffer; adjusting a convergence point of the selected background image; extracting an object image to be composed to the background image; displaying guidance information indicating a position at which the object image can be composed to the background image; and composing the object image to the background image according to the guidance information. Thus, when 3D images, each having a different convergence, are composed, the convergence point of a background image is adjusted and guidance information indicating a position at which an object image is to be composed is provided, thereby conveniently and accurately composing the 3D images.

Mobile terminal and 3D image composing method thereof

A method for executing a menu in a mobile terminal and a mobile terminal thereof are disclosed, wherein the method includes displaying a first screen on a display unit of the mobile terminal, detecting whether an audio output device connection signal is generated by an external audio output device being connected to the mobile terminal while the first screen is displayed, and displaying a second screen including an audio output-related menu if the audio output device connection signal is generated.
