Abstract: According to one embodiment, an electronic device includes a storage, a first display processor, an input module, and a second display processor. The storage is configured to store stroke information corresponding to a plurality of strokes. The first display processor is configured to display the plurality of strokes. The input module is configured to input a retrieve key for retrieval of the plurality of strokes. The second display processor is configured to display a enlarged or reduced display area including a stroke part, which is retrieved from the stroke information and corresponds to the retrieve key, and strokes other than the stroke part.

Abstract: According to one embodiment, when a first stroke is inputted on a display, an electronic device displays an elongate first area in a first style, the first area including a display area of the first stroke, displays a second area other than the first area in a second style different from the first style, and displays one or more first handwriting candidates on the display based on the first stroke. The electronic device determines to enter, when one of the one or more first handwriting candidates is selected, the selected first handwriting candidate in place of the first stroke. The device determines to enter the first stroke when an operation on the second area is detected.

Abstract: According to one embodiment, a method of displaying an image on an electronic device includes acquiring a first image created by a first device comprising a first screen of a first size; and displaying the first image by the electronic device including a second screen of a second size different from the first size. The first image is displayed on the second screen under a first magnification based on the first size and the second size.

Abstract: According to one embodiment, a system stores a plurality of contents in a storage medium, each content includes handwritten data including stroke data corresponding to strokes which are handwritten, image data corresponding to the strokes, and retrieval information for retrieving the handwritten data. The system provides, upon receiving a retrieve request including a character string from a terminal, to the terminal either the handwritten data in the content corresponding to first retrieval information, the first retrieval information corresponding to the character string from among retrieval information of the plurality of contents, or the image data in the content corresponding to the first retrieval information.

Abstract: A display apparatus configured to display three-dimensional video viewable by a viewer wearing stereoscopic-viewing glasses. The display apparatus includes: an input module; a display device; an image input module; a detection module; and a recording module. The input module receives video data. The display device displays the three-dimensional video based on the received video data. The image input module receives a captured image from an image-capturing device that captures an image of an area around the display apparatus and on a side facing the display device. The detection module detects an image of the stereoscopic-viewing glasses from the received captured image. The recording module records the received video data when the image of the stereoscopic-viewing glasses is not detected by the detection module.

Abstract: According to one embodiment, an electronic apparatus includes a layer creator and a storage processor. The layer creator creates, when a handwritten document including a first layer is displayed, a second layer. The storage processor stores first layer information and first stroke data if a first stroke is handwritten in a first region of the first layer, and stores second layer information and second stroke data if a second stroke is handwritten in a second region of the second layer, the first layer information indicative of the first region, the first stroke data corresponding to the first stroke, the second layer information indicative of the second region, and the second stroke data corresponding to the second stroke.

Abstract: One embodiment provides an electronic apparatus, including: a display controller configured to perform a display control of video data, the video data including a main video and a sub video which are assigned in different time zones; and a detector configured to detect whether the main video or the sub video is currently to be displayed, wherein the display controller performs the display control so as to perform a 3D display of the video data when the detector detects that the main video is currently to be displayed, and perform a 2D display of the video data when the detector detects that the sub video is currently to be displayed.
