An electronic device includes a projector, an operating method of an electronic device including a projector, and a non-transitory computer-readable recording medium having recorded thereon instructions for performing the operating method. The electronic device includes a communicator configured to exchange data with an external device, a projector configured to project light; a sensor configured to measure a degree of proximity between the electronic device and an installation surface on which the electronic device is to be installed, and a controller configured to control the communicator and/or the projector based on the degree of proximity measured by the sensor.

Projection apparatus and operating method thereof

An electronic device including an optical module, a method of operating the electronic device including the optical module, and a non-transitory computer-readable recording medium having recorded thereon a program for performing the method. The electronic device includes an optical module configured to project content on a projection surface and a processor configured to determine whether the electronic device is positioned within a predetermined range of a projection surface and control the optical module to project the content onto the projection surface based on the determination.

Electronic device and method

A projection lens system which is arranged between an object side at which a micro-display panel is located and an image side at which a screen is located, and includes an aperture stop; a front lens group arranged at an object-side of the aperture stop and having a positive refractive power; a rear lens group arranged at an image-side of the aperture stop, the rear lens group including a first aspherical lens at a position closest to the image side and a second aspherical lens adjacent to an object-side surface of the first aspherical lens; and an aspherical mirror having a negative refractive power and reflecting light coming from the rear lens group toward the image side.

Projection lens system and projection system

A pointer control method and an apparatus in an electronic device are provided. The pointer control method in the electronic device includes detecting a multi touch, determining a coordinate of a pointer based on the multi-touched points, and displaying the pointer at the determined coordinate.

Pointer control method and electronic device thereof

A video apparatus includes a receiving unit to receive a selection command for at least one item from among a plurality of items, and a control unit to provide quantity information about alternative items to the selected item when at least one item is selected. A user is provided with the quantity information about the alternative items placed alongside a currently selected item, and thus able to intuitively determine the distribution of the items and a direction in which he may choose to view or select the items. As a result, the user is able to navigate through a plurality of items with convenience. The user is also provided with the information about the items currently not displayed on a display, and thus does not feel inconvenience caused by the limited size of the display screen.

Video apparatus providing a user interface (UI) and method thereof

A method for providing keywords and a video apparatus applying the method are provided. The method for providing keywords includes separating metadata from content, extracting keywords in the content from the metadata, and generating a keyword list using the keywords and images related to the keywords. It is thus possible to display the keywords together with the images related to the keywords, so a user may register desired keywords more conveniently without needing to manually individually input keywords.

Method for providing keywords, and video apparatus applying the same

A method of displaying a list is provided. The method includes receiving a user command to display a list of multimedia content, determining at least one multimedia content which matches a pre-stored keyword from among a plurality of multimedia content included in the list, in response to the user command, and displaying the list including the plurality of multimedia content based on the result of the determination, wherein the displayed list displays the pre-stored keyword as overlapping the least one multimedia content matching the pre-stored keyword from among the plurality of multimedia content.

Method for providing multimedia content list, and multimedia apparatus applying the same

A method for providing multimedia and a multimedia apparatus applying the same. The method for providing multimedia includes searching for content related to keywords and generating channels to provide the content found as a result of searching. Therefore, it is possible for a user to more conveniently use Internet multimedia content using a TV.
