Abstract: A method, system, apparatus, article of manufacture, and computer readable storage medium provide the ability to fill pixels of an image. An area of the image is obtained and one of the pixels is identified as an anchor pixel. Waves are created based on the anchor pixel and placed into a collection of waves waiting to be processed. Each of the waves in the collection is processed. A type of pixel in front of a current wave being processed is determined. If the pixel is fillable, the pixel is filled, the wave is advanced, and child waves are updated. If the pixel is blocking the advancement of the wave, the current wave is updated (e.g., via shrinking or splitting), and child waves are updated. Once all waves have been processed, the area of the image is displayed based on the fill.

An image combining unit combines image data obtained through conversion by the image data conversion unit with the predetermined oblique-view image data to generate composite image data. The composite image data is displayed on the display panel unit.

An enhanced luminance layer is generated through composition using the HVS response layer and the enhanced background luminance layer as inputs.

Abstract: A dynamic localized contrast enhancement method for images and computer readable medium is revealed. The method includes multiple steps. First scan each image frame dynamically by a window whose size is smaller than that of the image frame.

The distribution histogram shows a relationship between the color feature value and a corresponding count of the pixels while the count represents the amount of the pixels with the color feature value in the window. Finally, perform contrast stretching according to the distribution histogram so as to improve the contrast in the image frame significantly.

Abstract: Image processing may be performed to generate a color image for display on a color display screen and a monochrome image for display on a monochrome display screen, where an overlap of the images may produce a resultant color image at one or more depths. The one or more depths may be determined by an amount of blur applied to one image and an amount of sharpness applied to other. The one or more depths may be determined by a gamma value of the monochrome image. Since the monochrome display screen may have fewer or no color filters and/or a lower resolution, the monochrome display screen may pass more light than conventional color display screens. As such, less light can be used to illuminate color images displayed at different depths using a color display screen and a monochrome display screen, thereby reducing energy consumption of the display device.

Abstract: An overdrive device includes a training unit, an analysis unit and a Contrast adjustment unit. The training unit establishes a luminance difference look-up table (LUT) having an R2 number of luminance differences. Each of the R2 number of luminance differences represents a luminance difference between a measured display luminance value and a target luminance value of a display device when each of first and second viewing angle images correspond to any value of a grayscale range R. With respect to first and second viewing angle input image data, for pixel data therein corresponding to a same pixel position, the analysis unit looks up the luminance difference LUT to obtain a looked-up luminance difference, and accordingly calculates a luminance difference index. The contrast adjustment unit partially adjusts the grayscale of the second viewing angle image according to the luminance value index to obtain headroom for an overdrive operation.

Abstract: A VCI (visual context indicator) color is assigned deterministically and proactively at runtime to user data contexts, and is not stored in the database, spreadsheet, or other context. VCI colors can be high contrast friendly colors. The same color is assigned to a given context each time the application runs unless the context's identifying property has changed. Color assignments are not made by users or by the application's designer, but are done instead by hashing from a context's identifying property into a VCI color palette containing, e.g., eight to sixteen colors. Unlike text-selection coloring, VCI coloring is based on the user data context's identifying property. The color assignment visually indicates context by displaying the context's name in the VCI color, or by displaying a graphical element in the VCI color near the context name. VCI color assignment also shows the occurrence and result of changes in user data context.

Abstract: Techniques for improving the performance of vector-based, fluid motion simulation techniques. The techniques may be implemented in procedural painting algorithms that employ a vector-based, fluid motion simulation technique to help achieve dynamic, serendipitous behaviors of painting at good interactive rates even on relatively low-powered devices. Instead of employing polygons in a procedural painting algorithm that are combinations of pigment and water, a technique may be employed in which the polygons are separated into pigment polygons and water polygons. The water polygons are not rendered; only the pigment polygons are rendered. To improve the performance of the wetness determination at vertices of the pigment polygons, a technique may be used that first rasterizes all of the water polygons into a buffer, which may be referred to as a wetness layer or wetmap; the wetness at a vertex is then determined by sampling this buffer or layer at the vertex's position.

Abstract: A developer tool is used to programmatically calculate the contrast between the text and background in a user interface. A luminosity ratio is automatically calculated by the tool by capturing an image of a user interface, archiving user interface elements that do not contain text, performing optical character recognition on the remaining user interface elements to find pixels on the text part of the user interface element and pixels on the background part of the user interface element, and finally calculating the luminosity ratio. Results including errors, warnings and luminosity ratio for one or more hotspots in the image can be returned. Results can be used to identify user interface elements that comply or fail to comply with visibility guidelines for contrast between user interface text and background.
