Various examples of approaches for using and implementing cascaded text formatting within electronic publishing and display mediums are described herein. In an example, a method for analyzing and re-formatting a stream of text, includes: obtaining a stream of human-readable text in a natural language processing (NLP) parser to identify parts-of-speech and key phrases in a proper sentence; tagging the identified parts-of-speech according to the respective parts and key phrases; generating a text cascade arrangement for a display of the proper sentence by applying predefined rules to the part-of-speech and key phrases, where such a display of the proper sentence provides breaks and cascading, including indentations, according to the pre-defined rules; and outputting an electronic display of the proper sentence which includes the text cascade arrangement. Other examples of methods of converting text, formatting text, and displaying text, with such text cascade arrangements and related formats, are also disclosed.

A system, method and non-transitory, computer-readable storage medium are disclosed for implementing dynamic layout rules for attributed text strings having different type styles. In some implementations, developers can use an Application Programming Interface (API) or a design tool to specify dynamic text layout rules for rendering attributed text strings in a user interface (UI). Various text attributes associated with the different type styles (e.g., font metrics) are dynamically adjusted based on the dynamic text layout rules to improve the readability of the text when, for example, font sizes are adjusted. In some implementations, one or more parameters of a text container, text container region, line-fragment or display object are dynamically adjusted based on the dynamic text layout rules to improve the readability of the text.

According to an aspect, a display device includes an image display panel in which pixels each including first to fourth sub-pixels are arranged in a two-dimensional matrix; and a signal processing unit that converts an input signal into an output signal and outputs the generated output signal to the image display panel. The signal processing unit determines an expansion coefficient, obtains a generated signal of the fourth sub-pixel in each pixel based on input signals of the first to the third sub-pixels in the pixel itself and the expansion coefficient, obtains an output signal for the fourth sub-pixel in each pixel based on a generated signal of the fourth sub-pixel in the pixel itself and a generated signal of the fourth sub-pixel in an adjacent pixel to be output to the fourth sub-pixel.

A display device includes: a display unit including pixels arranged in a matrix therein, each of the pixels including a first sub-pixel that displays a first color component, a second sub-pixel that displays a second color component, a third sub-pixel that displays a third color component, and a fourth sub-pixel that displays a fourth color component; and a signal processing unit that receives input signals that are capable of being displayed with the first sub-pixel, the second sub-pixel, and the third sub-pixel, and calculates output signals to the first, second, third, and fourth sub-pixels. The signal processing unit generates converted input signals with changed saturation among the input signals. The signal processing unit calculates output signals to the first sub-pixel, the second sub-pixel, and the third sub-pixel based on the converted input signals and an amount of increase in brightness caused by the fourth sub-pixel.

There is provided a character string display device including a character string display unit (10) including a plurality of display elements (110) arrayed two-dimensionally, and a display controller (20) configured to cause the character string display unit (10) to display a predetermined character string pattern by controlling display states of the plurality of display elements (110). In the character string display device, the display controller (20) is configured to cause the character string display unit (10) to display the character string pattern such that there is no blank line between consecutive character patterns of the character string pattern and that, when two display elements corresponding to the respective consecutive character patterns are adjacent to each other, a character pattern part corresponding to one of the adjacent display elements (110) is not displayed. The character string display device and a character string display method are simple and low cost, allow effective use of display space, and achieve higher legibility of a character string.

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.

Systems and methods are provided for laying out reflowable content for display, such as content of an electronic book, in a manner that may differ from spacing properties originally defined in a corresponding reflowable file. When an amount of spacing that the reflowable file indicates should be included in a given line exceeds a threshold that is set based at least in part on the available line display length, the layout may be adjusted to decrease the total spacing for the line without adjusting the display size of reflow objects within the line. The adjusted layout may include utilizing a scaled down amount of space relative to the spacing properties defined in the reflowable file, or applying a different alignment type than is indicated by the reflowable file.

An image generation device includes: a rasterizing portion generating, according string data, an element-blank image including a first element image indicating a first-type string element of a string and a blank image indicating a blank; an embedding portion identifying and embedding a second element image indicating a second-type string element of the string in the blank image; a first data storage portion in which a first data group used to generate the first element image is stored; and a second data storage portion in which a second data group including an image to be embedded as the second element image is stored. The rasterizing portion generates the first element image based on the first data group, and generates the blank image at a position where the second element image is to be embedded by identifying an embedding position of the second element image.
