摘要： A bridge is provided between an industry standard architecture (ISA) bus and a peripheral controller interconnect (PCI) bus and performs memory cycles on both buses simultaneously when a master on the ISA bus initiates a memory transfer. Data is steered between the ISA and PCI buses when a slave on the PCI bus claims the memory address within a predetermined time period after the memory cycle is initiated on the PCI bus. The ISA bus is isolated from the PCI bus when no slave on the PCI bus claims the memory address. This allows the memory cycle to be completed on the ISA bus, and the memory cycle on the PCI bus is terminated.

摘要： A method and arrangement is provided to support both fast Programmed Input/Output (PIO) and third party Direct Memory Access (DMA) data transfers between a system memory and Integrated Drive Electronics (IDE) drives. A DMA controller attached to an ISA bus supplies address, read and write signals in third party DMA data transfers. An IDE controller provides control signals to support the DMA data transfers. The IDE controller additionally provides address and control signals to support the PIO data transfers at local bus speeds. A local bus-ISA bridge is incorporated to support the system memory that resides on the local bus. An arbitration circuit arbitrates access to the ISA bus, and allows the IDE controller to seize the ISA bus for fast PIO data transfer.

摘要： A photo filter (e.g., artistic) light field effect system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. Execution of programming by a processor configures the photo filter light field effect system to apply a photo filter selection to: (i) a left raw image or a left processed image to create a left photo filter image, and (ii) a right raw image or a right processed image to create a right photo filter image. The photo filter light field effect system generates, a photo filter light field effect image with an appearance of a spatial rotation or movement, by blending together the left photo filter image and the right photo filter image based on a left image disparity map and a right image disparity map.

摘要： A photo filter (e.g., multi-dimensional) light field effect system includes an eyewear device having a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. Execution of programming by a processor configures the system to create an image in each of a least two dimensions and create a multi-dimensional light field effect image with an appearance of a spatial rotation or movement and transitional change, by blending together a left photo filter image and a right photo filter image in each dimension and blending the blended images from all dimensions.

摘要： An eye movement tracking device that can be mounted to standard eyeglasses as disclosed. The device comprises an illumination source, a time-of-flight (TOF) camera and a processor. The source transmits energy within a frequency band from a location proximate to an eye of a person, such that at least a first portion of the transmitted energy is reflected off a lens of eyewear worn by the person to subsequently reflect off the eye, and such that at least a second portion of the transmitted energy is transmitted through the lens to reflect off objects in the person's environment. The TOF camera detects reflections of at least the first portion of the transmitted energy, and distinguishes them from other energy detected by the TOF camera in said frequency band, based on TOF principles. The processor uses the detected reflections of the first portion of the transmitted energy to determine eye position.

摘要： Systems and methods for increasing the resolution of a depth map by identifying and updating false depth pixels are described. In some embodiments, a depth pixel of the depth map is initially assigned a confidence value based on curvature values and localized contrast information. The curvature values may be generated by applying a Laplacian filter or other edge detection filter to the depth pixel and its neighboring pixels. The localized contrast information may be generated by determining a difference between the maximum and minimum depth values associated with the depth pixel and its neighboring pixels. A false depth pixel may be identified by comparing a confidence value associated with the false depth pixel with a particular threshold. The false depth pixel may be updated by assigning a new depth value based on an extrapolation of depth values associated with neighboring pixel locations.
