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.

Content data of a display target is acquired in accordance with a user's operations and is used to determine a configuration of a display image. Of the regions to be rendered using fonts in the display image, the region in which a character is to be displaced by a very small amount is determined. The characters targeted for displacement are rendered while being displaced over time in accordance with predetermined displacement rules. The characters not targeted for displacement are rendered in a reference position. With all characters rendered, the display image is completed and output. The processes of S12 to S24 are repeated until display is terminated.

A display method is applied to electronic equipment including a display assembly. A display content displayed by the display assembly includes a background and an object for reading located on the background. The display method includes: differentiating grayscales of background pixels of the background; and displaying the background based on the background pixels with the differentiated grayscales, and displaying the object for reading.

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.

A method involves receiving, at a host device, information indicative of available bandwidth on a variable bandwidth connection between the host device and a display control device, which may be based on monitoring a signal level on the connection, a link radio modulation mode, traffic on the connection, or the data rate of any return signals from the display control device. The method includes setting one or more parameters used to generate the display data that change compressibility of the display data based on the information, where compressibility of the display data affects efficiency of compression of the display data, and where the setting of the parameters may be based on a compression algorithm used when compressing the display data. The method includes generating the display data using the one or more parameters, compressing the display data, and transmitting the display data to the display control device.

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.
