An escape indicator display system includes a storage unit, a display unit and a control unit. The storage unit includes a database, plural datarows in the database, a code corresponsive to each datarow and having at least one field, escape indication information in the field and including plural pieces of image information, text information, color information or size information. The control unit is coupled between the display unit and the storage unit for selecting a country or district name, and the reads the datarow of the code corresponsive to the country or district name from the database by the processor, and displays the escape indication information in the field on the display unit, so as to detect the location of the system and display the escape indicator image according to local escape indicator regulations.

An electronic device and method are disclosed herein. The electronic device includes a display, and a processor. The processor implements the method, including: acquiring a background image of a screen generated for display, a region of interest (ROI) where a user interface (UI) element is to be displayed, calculating a value indicating a shape complexity of the ROI, dividing the ROI into a plurality of clusters according to designated attributes, calculating difference values indicating a contrast between each of the plurality of clusters and the UI element, identifying a minimum difference value from among the difference values as a contrast difference value, calculating a result value indicating a degree of visibility of the UI element relative to the background image, determining an image effect to be applied to the UI element, based on the result value, and display to the altered ROI the UI element.

Near-to-eye displays support a range of applications from helping users with low vision through augmenting a real world view to displaying virtual environments. The images displayed may contain text to be read by the user. It would be beneficial to provide users with text enhancements to improve its readability and legibility, as measured through improved reading speed and/or comprehension. Such enhancements can provide benefits to both visually impaired and non-visually impaired users where legibility may be reduced by external factors as well as by visual dysfunction(s) of the user. Methodologies and system enhancements that augment text to be viewed by an individual, whatever the source of the image, are provided in order to aid the individual in poor viewing conditions and/or to overcome physiological or psychological visual defects affecting the individual or to simply improve the quality of the reading experience for the user.

A display control apparatus includes an acquisition unit that acquires an image, a memory that stores multiple images acquired by the acquisition unit, a recognition unit that recognizes a size of a character included in an image to be displayed on a display from among the images stored on the memory, and a display controller that causes the display to display the images stored on the memory while switching from one image to another every set time period. The display controller determines a display setting of the image to be displayed on the display in response to the size of the character included in the image that the recognition unit has recognized and causes the display to display the image in the determined display setting.

A system is described for automatically calibrating a display device based at least on information relating to a user of the display device. The system obtains visual acuity information or pupillary information of the user. The system then determines a value of a display parameter of the display device based at least on the visual acuity information or the pupillary information of the user. The determined value is then provided for application to the display device. Other information may also be used in determining the value of the display parameter, such as user input, demographic information of the user, display device specific information, user environment information, displayed content information, or application context information. An algorithm may be used that determines the display parameter based on such information. The algorithm may comprise a model obtained through machine learning.

A video input interface receives video data. An OSD circuit draws an intermediate layer in a target region in which an OSD character is to be overlaid on the video data, and overlays the OSD character on the intermediate layer.

In some implementations, a font generator device may receive input text that includes one or more characters. The font generator device may generate a disability-oriented font based on one or more parameters that relate to a vision deficiency, wherein the disability-oriented font is readable by users that have the vision deficiency and unreadable by users that do not have the vision deficiency. The font generator device may transform the one or more characters included in the input text into the disability-oriented font. The font generator device may generate an output that represents the input text using the disability-oriented font based on transforming the one or more characters included in the input text into the disability-oriented font.

A system may render glyphs based on stored textures without loss of quality at subpixel scales. The system may determine a content of a pixel of a display corresponds to a glyph, determine a subpixel alignment offset of a specified screen coordinates for the glyph with respect to the pixels of the display, based on the subpixel alignment offset, select one or more versions of the glyph from a plurality of versions of the glyph, a first version of the glyph of the plurality of versions of the glyph having a corresponding first subpixel alignment offset and a second version of the glyph of the plurality of versions of the glyph having a corresponding second subpixel alignment offset, and generate a display version of the pixel based on the selected one or more versions of the glyph and the subpixel alignment offset of the specified screen coordinates.
