Abstract: A data browsing apparatus displays data automatically in an automatic page-turning mode. The data browsing apparatus has dynamic picture display parameters comprising a frame display time (w), a frame display pitch (m), and a display priority (r). The dynamic picture display parameters may be calculated based on automatic page-turning options designated by users. Dynamic pictures are displayed with accuracy at the automatic page-turning interval.

Abstract: A system and method for transferring files from a sending user to a recipient, utilizes a drag-and-drop graphical user interface. To send a file to a recipient, the user drags and drops onto the recipient's icon an icon, or set of selected icons, representing the file(s) to be transmitted. Information pertaining to the file and the recipient is captured from the icons and used to establish a session between the sender and the recipient. The file is transferred to the recipient via the established session.

Abstract: A pixel of a color video image is converted from one color format having luminance and chrominance signals, e.g., YUV format, to a destination format, e.g., RGB or CMY formats, by forming luminance and chrominance component words which include partitioned words representing various color components of the luminance and chrominance signals. The luminance and chrominance component words are summed using a partitioned addition operation to thereby accumulate the various color components of the luminance and chrominance signals simultaneously and in parallel. Formation of the luminance and chrominance component words is, in some instances, done by a load and store unit of a central processing unit while a graphics execution unit simultaneously sums the luminance and chrominance components using the partitioned addition operation. By using this technique, conversion of pixels of a color motion image from YUV format to a different format, e.g.

Abstract: Graphics systems manipulate data embodying one or more objects for display. The objects are typically represented by a plurality of faces. In order to rasterize an object for display utilizing a plurality of rasterization engines, the present invention partitions at least one face of the object into a plurality of sub-faces according to a first cost function representing cost of rasterizing the face, and assigns the sub-faces to the plurality of rasterization engines for rasterization. The rasterization engines rasterize the sub-faces to generate pixel data representing the object for display. The partitioning of the face of the object into the plurality of sub-faces may be based upon a second cost function representing cost of rasterizing at least one of the sub-faces. Preferably, each of the sub-faces has equal rasterization cost and each of the sub-faces do not overlap one another.

Abstract: A target image to be retrieved and a processing mode of the target image are stored in a magneto-optic disk as a job in a job file by using a computer which is independent of an image processing apparatus. The magneto-optic disk is set into the image processing apparatus. When the magneto-optic disk is set, whether or not the job file is stored in the disk is detected. When the job file is stored, whether or not a job including a processing mode which cannot be executed by the image processing apparatus exists in the job file is discriminated. When a job cannot be executed, such fact is displayed and execution of the job is skipped.

Abstract: A method of performing color control in a digital video decoder while minimizing memory bandwidth. A decoded color image bit map is stored in a RAM in lines corresponding to horizontal lines of pixels. Each line also has dedicated bytes for a corresponding color look up table comprising a control field and color address fields. Entries in separate preloaded color component tables are addressed by the color address fields. A transparency bit in the control field is used to select modifiers to the data in the address fields for transparency mode.

Abstract: A method for improving the performance of a graphics system includes the steps of allocating appropriate pixels to slices of memory such that corresponding subsets of bits of neighboring pixels are allocated to different slices of memory, where `neighboring pixels` includes both consecutive pixels in a scan line, or pixels in consecutive scan lines. In addition, hardware is provided that allows for the individual memory slices to be independently accessed, thus allowed each slice to access data from a different 64 bit word in video memory during one video access period. Controllers which independently access the memory slices are advantageously totally time independent, to allow the most flexibility in the starting and finishing of the access of the memory slice. Performance is further gained by buffering of both the read and write requests to the video memory.

Abstract: A method and apparatus for configuring memory within a dual access dynamic random access memory (DRAM) frame buffer so that array conflicts are reduced between neighboring pixels. The present invention DRAM frame buffer contains a number of arrays (e.g., 48), each array containing a number of rows (e.g., 256), each row contains a number of bytes (e.g., 1024). Rows of arrays are used to store frame buffer information within the DRAM. There is a single row of sense amplifiers per array, so rows of the same array conflict since they cannot be open at the same time. In an alternative embodiment, some neighboring arrays share the same row of sense amplifiers so neighboring arrays can conflict. The DRAM memory is configured such that for any given central pixel, its four spatially neighboring pixels (up, down, right and left) are not stored (1) in a different row of the same array as the central pixel nor (2) stored in a different row of any other conflicting array.

Abstract: A computer system having a pixel processing unit with multiple subprocessors receives positional data defining graphical objects from the CPU and writes pixel data into the image memory, and a display driver produces an image which partially includes the rendered pixels. The pixel processor is used to access patches of multiple contiguous pixels at a time, and process them in parallel. The patches used are defined, within the overall geometry of the image, to have aligned corners. The unit is also connected to receive synchronization signals from the display driver, conditioned on whether the current line being accessed by the driver is within a specified range of lines in the image space.
