摘要： A method and apparatus for rendering an object to have a bump texture begins when object parameters for the object are received. The object parameters include bump mapping coordinates and physical display coordinates. From this information, a first and second axis specific tables are generated to provide a plurality of axis specific bump intensity values. The first axis specific table relates to bump intensity values along a first axis of the bump and the second axis specific table relates to bump intensity values along a second axis of the bump map. In essence, the axis specific tables represent the bump map being mathematically repositioned to be in the same plane, with respect to the fixed coordinates of the display, as that of the object. With the tables generated, the object is rendered on a pixel by pixel basis, wherein the first and second axis specific tables are addressed for each pixel to retrieve a corresponding first and second intensity values (i.e., Bu×(fu·L), Bv×(fv·L)). The first and second intensity values are combined to produce a bump-shading component, or bump intensity value, (&Dgr;N·L) for the given pixel. The bump-shading component (&Dgr;N·L) is then combined with the normal shading component (N·L) to produce the shading function for the given pixel. The resulting shading function is then combined with rendered pixel data to produce the resultant display, or pixe,l data for the given pixel.

摘要： An integrated circuit modeling system facilitates automatic design of register based hardware devices by generating major pieces of the development outputs from a single input, such as a single register specification source file. The modeling code is kept coherent for all major phases of design and testing. The register specification source file contains all the register information about the device being developed. For example, each register defined in the file contains information about its offset (within its register space), access permissions, size, and field specifications. The system uses a series of associated pre-stored modeling templates in different programming languages, that access the register specification source file and automatically generate behavioral model register code and IC simulation code.

摘要： The techniques of this disclosure are applicable to backlight display devices. For such devices, the backlight may have different backlight intensity settings in order to promote power conservation. The techniques of this disclosure may apply different adjustments to the display, depending on the backlight intensity setting. In one example, different color correction matrices may be applied for different backlight settings in order to achieve desirable adjustments in the device at the different backlight settings. The adjustments described herein may address chrominance shifts due to different backlight settings as well as cross-talk between color channels. The techniques may also be applicable to organic light emitting diode (OLED) displays that have different luminance settings, and some described techniques may be applicable to displays that have static or fixed luminance output.

摘要： Described herein are methods, systems and apparatus to improve imaging sensor production yields. In one method, a stereoscopic image sensor pair is provided from a manufacturing line. One or more images of a correction pattern are captured by the image sensor pair. Correction angles of the sensor pair are determined based on the images of the correction pattern. The correction angles of the sensor pair are represented graphically in a three dimensional space. Analysis of the graphical representation of the correction angles through statistical processing results in a set of production correction parameters that may be input into a manufacturing line to improve sensor pair yields.

摘要： A graphics multi-media integrated circuit (GMIC) is connected to a host processor over two serial links: a half duplex bi-directional serial link which accords to a display serial interface protocol, and a uni-directional serial link which accords to a camera serial interface protocol. The GMIC receives packets from the host over the half duplex bi-directional serial link and processes these packets. The GMIC sends packets over the uni-directional serial link. A packet from the host can request a processing operation by the GMIC or can initiate a memory operation at the memory of the GMIC. The GMIC can also send packets to the host to initiate a host memory operation and may be connected to a display over a bi-directional serial link and to a camera over a uni-directional serial link and a bi-directional control link allowing the host to control the display and camera.

摘要： To derive a Hamming code to manage data errors a set of at least four parity bit positions is selected for parity bits which will protect a set of data bits (where each data bit has a data bit position in the data bit set). A syndrome is determined for each data bit position. This involves selecting a unique sub-set of at least three parity bit positions. The unique sub-set shares at least one parity bit position with at least one other unique sub-set of at least three parity bit positions. A parity bit value may then be calculated for each parity bit position based on the determined syndromes. The header of a packet may be provided with a word which defines the length of the packet and an error management code generated utilizing this word so that errors in the word may be detected and, possibly, corrected.

摘要： A method and apparatus improves an auto focus system by altering, such as by positioning, at least one lens of a digital camera to a plurality of predetermined nonuniform lens positions corresponding to predetermined nonuniform lens position data. The method and apparatus selects a final lens position for the lens based on the predetermined nonuniform lens position data. In one example, a fixed number of predetermined nonuniform lens positions define a set of lens positions used to capture images during an auto focus operation. A final image is captured using a final lens position. The final lens position is determined by comparing focus metric information from each of the frames obtained at the various predetermined nonuniform focus lens positions and selecting the frame with, for example, the best focus metric as the lens position to be used for the final picture or image capture.
