45results about How to "Reduced legibility" patented technology

A computer implemented system, plug-in application and method for composing a formatted text input to improve legibility, readability and / or print economy while preserving the format of the text input and satisfying any user selected aesthetic constraints. This is accomplished by reading in blocks of text input having defined characters including letters and punctuation in a given input format. A language unit such as a lexical or sub-lexical unit, a subset of punctuation or another defined unit for a particular language is examined and an information measure (IM) is assigned to each character in the language unit indicating the predictability of that character to differentiate the language unit from other language units. Typically, multiple different IMs are assigned to each character and combined to form a combined IM (CIM). The process is repeated for at least a plurality of language units and typically until all the text input in the block has been analyzed and information measures assigned to all of the characters. An adjustment to a physical feature is determined for each character in the plurality of units to modify the visual prominence of that character according to the values of the assigned information measures and a permitted range of physical variation for the block. The adjustments are applied to each character to compose the text input consistent with the input format.

A video processing system enhances quality of an overlay image, such as a logo, text, game scores, or other areas forming a region of interest (ROI) in a video stream. The system separately enhances the video quality of the ROI, particularly when screen size is reduced. The data enhancement can be accomplished at decoding with metadata provided with the video data for decoding so that the ROI that can be separately enhanced from the video. In improve legibility, the ROI enhancer can increase contrast, brightness, hue, saturation, and bit density of the ROI. The ROI enhancer can operate down to a pixel-by-pixel level. The ROI enhancer may use stored reference picture templates to enhance a current ROI based on a comparison. When the ROI includes text, a minimum reduction size for the ROI relative to the remaining video can be identified so that the ROI is not reduced below human perceptibility.

P-polarized display light is projected onto a Fresnel mirror sealed body from an HUD unit, whereby reflection at the front surface and the back surface of the Fresnel mirror sealed body is suppressed. The angle of incidence of display light on the Fresnel mirror sealed body is set close to a Brewster's angle to suppress the reflection further. The p-polarized display light is generated by producing linearly polarized display light by a liquid crystal display that incorporates a polarizing plate and then adjusting its polarization direction by a half-wave plate or by inputting unpolarized display light to a polarizing plate. The use of p-polarized light makes it possible to suppress unnecessary reflection. The reflection can be minimized by setting the incident angle at the Brewster's angle.

Font glyphs generated in accordance with the invention are more efficient to use when printing hardcopies due to intelligently arranged negative / positive space that utilizes print compound bleeding, when available, and display only the most distinct sections of each font glyph, assisting in maintaining sufficient text legibility.

An updated region encoding unit detects an updated region in a frame of an inputted image signal and encodes the updated region. A retransmission candidate tile extracting unit extracts from within a screen a tile which does not belong to an updated region in a current frame and which is a partial region transmitted after encoded with a quality equal to or less than a first quality. A character likelihood estimating unit, with respect to a tile extracted by the retransmission candidate tile extracting unit, calculates a likelihood value indicating likelihood that the tile is a character region. A character-likelihood-order intra update unit selects a tile in decreasing order of the likelihood value from among tiles extracted by the retransmission candidate tile extracting unit, and encodes the tile with a second quality which is higher than the first quality and transmits the result.
