Abstract: Embodiments relate to compression and decompression of textures. A texel block (10) is compressed by specifying two major directions in the texel block (10) and defining the profiles of how the texel values change along the respective directions. The resulting compressed texel block (30) comprises two value codewords (31, 32), two line codewords (35-38) and a function codeword (33, 34). The two value codewords (31, 32) are employed to calculate two texel values for the texel block (10). The line codewords (35-38) are employed to determine equations of two lines (20, 22) coinciding with the two major directions in the texel block (10). Signed distances are calculated for each texel (12) from the texel position in the texel block (10) and to the two lines (20, 22). The signed distances are input to a function defined by the function codeword (33, 34) to output two values from which weights are calculated and applied to the two texel values in order to get a representation of the texel value of a texel (12).

Abstract: The distance between projection coordinates to which the center of an image are projected and the center coordinates are added to the projection coordinates to obtain projection center coordinates. The distance is added to the coordinates to which the four corners of the image are projected to obtain projection four-corner coordinates. A distance shorter than the minimum of the distances between the projection four-corner coordinates and the projection center coordinates is decided as an output margin distance. Projection source coordinates to be projected to coordinates apart from the projection center coordinates by the output margin distance are obtained. A maximum of the distances between the projection source coordinates and the projection center coordinates is decided as an input margin distance. Divided images decided based on ½ of horizontal size of the image and the input margin distance are deformed and outputted.

Abstract: A system provides a recommendation of food items to a user based on nutritional preferences of the user, using a head-mounted display device (HMDD) worn by the user. In a store, a forward-facing camera of the HMDD captures an image of a food item. The food item can be identified by the image, such as based on packaging of the food item. Nutritional parameters of the food item are compared to nutritional preferences of the user to determine whether the food item is recommended. The HMDD displays an augmented reality image to the user indicating whether the food item is recommended. If the food item is not recommended, a substitute food item can be identified. The nutritional preferences can indicate food allergies, preferences for low calorie foods and so forth. In a restaurant, the HMDD can recommend menu selections for a user.

The apexes of the polygon mesh displaced on the basis of the textures mapped in all the regions are connected to obtain grain-given polygon data.

Accordingly, it is possible to provide a device and method for mapping a color gamut, which can determine an optimal color gamut corresponding to a change in control condition, and accordingly improve color accuracy and color reproducibility.

Abstract: A system improves the performance of compositing individual images representing graphic layers into a composite image. The system may subdivide an image area of the composite image into cells such that for each one of the cells, either none of the graphic layers overlap within a respective one of the cells or all of the graphic layers that overlap within the respective one of the cells overlap throughout the respective one of the cells. A composition operation may be applicable to composite the respective one of the cells. The system may determine which processor generates the respective one of the cells based on which one of the processors is able to perform the type composition operation. The processor may generate the respective one of the cells by processing the composition operation.

Abstract: Some embodiments provide an image-viewing application. The image-viewing application calculates an average aspect ratio of several images for display in an image viewing area. A first image in the several images has a first aspect ratio and a second image in the several images has a second, different aspect ratio. The application determines a number and size of regions of the image viewing area for displaying the several images. The regions have the calculated average aspect ratio, and each image is for display in a different one of the regions. The application displays the several images in the regions of the image viewing area. Each displayed image has a same visual weighting. The first image is displayed at the first aspect ratio and the second image is displayed at the second aspect ratio.

Abstract: A method and an apparatus for operating a graphic menu bar and a recording medium using the same, suitable for a portable electronic device having a touch screen, are provided. First, a graphic menu bar is provided, which includes M graphic items arranged in sequence, where M is a positive integer. Next, the touch screen is divided into N display blocks along a coordinate axis direction for displaying N connected graphic items in graphic menu bar, where N is a positive integer smaller than M. When the touch screen detects a touch signal in display blocks and the touch signal is moved toward the coordinate axis direction for a first displacement, the graphic menu bar displayed on the touch screen is moved toward a direction opposite to the coordinate axis direction for a second displacement, and the second displacement is equal to the product of the first displacement and (M?N)/N.

A mapping algorithm may be selected based on location and/or color coordinates for pixel data being mapped. The apparatus and methods may be configured to map color coordinates differently depending on whether or not a pixel corresponds to a light source in an image and/or has special or reserved color values.

Abstract: The techniques disclosed herein use a compass, MEMS accelerometer, GPS module, and MEMS gyrometer to infer a frame of reference for a hand-held device. This can provide a true Frenet frame, i.e., X- and Y-vectors for the display, and also a Z-vector that points perpendicularly to the display. In fact, with various inertial clues from accelerometer, gyrometer, and other instruments that report their states in real time, it is possible to track the Frenet frame of the device in real time to provide a continuous 3D frame-of-reference. Once this continuous frame of reference is known, the position of a user's eyes may either be inferred or calculated directly by using a device's front-facing camera. With the position of the user's eyes and a continuous 3D frame-of-reference for the display, more realistic virtual 3D depictions of the objects on the device's display may be created and interacted with by the user.

Abstract: A display device includes an operation portion, a display portion, a character designating portion, and a display control portion. The display control portion displays the at least one character on the display portion. The display control portion displays, in a case where the at least one character displayed on the display portion includes a predetermined special character and the number of at least one display lines is not less than a threshold value, a dot pattern for an alternate character instead of a dot pattern for the special character. The display control portion changes, in a case where a designated character is the alternate character, the dot pattern for the designated character displayed on the display portion to the dot pattern for the special character.
