44results about How to "Reduced legibility" patented technology

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.

Processes and systems for creating and/or modifying font glyphs comprising the addition of variably-sized negative space perforations in various shapes placed among the glyph body black space and within the glyph body outline. Within each negative space perforation may be placed nested positive space perforations of variable size and shape.

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.
