Abstract: Image data systems and methods combine a plurality of images into a single multiple-palette image data file, or generate a selected image from the multiple-palette image data file. An exemplary embodiment receives first pixel information for a first pixel of a first image, the first pixel having a first color; receives second pixel information for a like-located second pixel of a second image, the second pixel having a second color; and specifies a color palette location value that identifies a first color palette array element in a first color palette of the first image and identifies a second like-located color palette array element in a second color palette of the second image. First color information stored in the first color palette array element defines the first pixel color. Second color information stored in the second image data color palette array element defines the second pixel color.

Abstract: Read completion buffer space is allocated in accordance with a preset limit. When a read request is received from a client, the sum of a current allocation of the read completion buffer space and a new allocation of the read completion buffer space required by the read request is compared with the preset limit. If the preset limit is not exceeded, read completion buffer space is allocated to the read request. If the preset limit is exceeded, the read request is suspended until sufficient data is read out from the read completion buffer.

Abstract: The present invention provides an apparatus which displays a plan wiring diagram and three-dimensional layout diagram by associating them with each other so that they can be viewed easily. A apparatus for displaying wiring includes a first storage for storing an image of a plan wiring diagram which shows parts and wirings and a second storage for storing a three-dimensional layout of an apparatus which incorporates the parts and the wirings, and a third storage for storing intermediate images transitional between a starting image in the plan wiring diagram and an ending image of a shape of the corresponding wiring in the three-dimensional layout. A processor displays the plan wiring diagram on the display device by retrieving the plan wiring diagram from the first storage based on a user's selection, and retrieves the intermediate images of a wiring from the third storage when the wiring is selected from the plan wiring diagram and displays transitions to the shape shown in the three-dimensional layout.

Abstract: A system for decoding a stream of compressed digital video images comprises a graphics accelerator for reading the stream of compressed digital video images, creating, starting from said stream of compressed digital video images, three-dimensional scenes to be rendered, and converting the three-dimensional scenes to be rendered into decoded video images. The graphics accelerator is preferentially configured as pipeline selectively switchable between operation in a graphics context and operation for decoding the stream of video images. The graphics accelerator is controllable during operation for decoding the stream of compressed digital video images via a set of application programming interfaces comprising, in addition to new APIs, also standard APIs for operation of the graphics accelerator in a graphics context.

Abstract: There is provided a graphics processing system that includes a main processing unit and a graphics processing unit (GPU). The main processing unit puts rendering commands generated using a graphics library in the queue of a command buffer in a main memory. In this process, the library function offered by the graphics library is converted into the rendering commands, without any rendering attributes retained in the library. The GPU reads and executes the rendering commands stacked in the command buffer, and generates rendering data in a frame buffer.

Abstract: In devices in which display data is read from a memory for display, display underflow in a processing block is alleviated by controlling a clock frequency driving the processing block. Stages of the processing block send underflow detection signals to underflow prevention logic. The underflow prevention logic controls the frequencies of clock signals generated by a clock generator to alleviate the underflow condition.

Abstract: An image processing apparatus processes compression encoded data of a moving picture and outputs image data divided into a plurality of frames for displaying of the moving picture on a display device. A host CPU outputs a decoding command and a drawing command separately from each other. The decoding process on the compression encoded data can be performed in an independent manner from the drawing process of reflecting the image data, which are the decoding results, on the display object. At this time, a display control section executes the drawing process based on the image data stored in a ring buffer in accordance with the drawing command. Therefore, the host CPU can freely control timings at which the moving pictures are displayed on the display device.

Abstract: Embodiments of the invention comprise methods and systems for modifying the geometry data of a CAD object through modification of an arbitrary cross section, the CAD object being stored within a computer aided design modeling system. The method includes receiving, from a user the position and orientation of a cross section plane, the cross section plane being arbitrarily positioned relative to the orientation of a CAD object, and wherein the arbitrarily positioned and oriented plane is intersecting the CAD object. The CAD system generates a user modifiable two dimensional cross section from the intersection of the cross section plane and the CAD object, the cross section having a plurality user modifiable control elements. Changes to the control elements are correspondingly made to the cross section plane and the CAD object.

Abstract: A system and method for maintaining certain content items at a fixed size and resolution and/or position relative to a device display are described herein. Fixed-scale content items are maintained at a given size, resolution, and/or, in some cases, position relative to a display regardless of changes in size and/or resolution of other displayed content.

Abstract: A system and method are provided for changing a display refresh rate. A first register is provided for storing at least one first refresh parameter in association with a first refresh rate. Additionally, a second register is provided for storing at least one second refresh parameter in association with a second refresh rate. Furthermore, logic is in communication with the first register and the second register. Such logic is adopted for selecting the first refresh parameter or the second refresh parameter, for the purpose of reducing artifacts resulting from a change from the first refresh rate and the second refresh rate.

Abstract: Systems and methods are provided for producing a rendered drawing or rendering from a detailed image of an object (e.g. photograph) resulting in a rendering that is photogrammetric and that preserves detail in the said image of said object. The combination of the metric nature and image detail preservation in a rendering resulting from the process enhances the usefulness of the rendering to users. The invention is useful in particular for large format renderings such as wire frame style drawings used for blueprints in the architecture, engineering and construction industry (AEC industry) when used for existing structures. The processes combine graphic arts techniques with photogrammetric techniques to preserve, fully or partially, information about an object as captured in image detail of said object and to present said information in photogrammetrically correct rendering, which rendering may be incorporated into drawings useful to and/or familiar to end users of said drawings.

Abstract: A portable display device transitions between a first and second state. The device has a display portion, a power source for supplying power in the first state and supplying less power in the second state than in the first state, a controller that drives the display portion, an operation portion that executes commands, and a mode storage portion that stores one of a first and second mode. The first mode corresponds to displaying preset information, and the second mode corresponds to particular information to be continuously displayed. The particular information is information displayed in the display portion when the device is in the first state. When the device is in the second state, the preset information is displayed in the display portion when the first mode is stored in the mode storage portion, and the particular information is continuously displayed when the second mode is stored in the mode storage portion.

Abstract: When displaying on a display (46) a plurality of thumbnails respectively corresponding to a plurality of image files selected from an external memory card (40), the CPU 26 determines whether each image file is a moving image file or a still image file, and creates an enlarged thumbnails by clipping the center of the thumbnail corresponding to the moving image file and enlarging it by an electronic zoom processing circuit (37). Then, a first screen including the plurality of thumbnails and a second screen including the enlarged thumbnail in place of the thumbnail corresponding to the moving image file on the first screen are alternately displayed.

Abstract: Systems and methods for determining a compression tag state prior to memory client arbitration may reduce the latency for memory accesses. A compression tag is associated with each portion of a surface stored in memory and indicates whether or not the data stored in each portion is compressed or not. A client uses the compression tags to construct memory access requests and the size of each request is based on whether or not the portion of the surface to be accessed is compressed or not. When multiple clients access the same surface the compression tag reads are interlocked with the pending memory access requests to ensure that the compression tags provided to each client are accurate. This mechanism allows for memory bandwidth optimizations including reordering memory access requests for efficient access.
