Abstract: A microlens structure includes lower lens layers on a substrate. A sputtered layer of glass, such as silicon oxide, is applied over the lower lens layers at an angle away from normal to form upper lens layers that increase the effective focal length of the microlens structure. The upper lens layers can be deposited in an aspherical shape with radii of curvature longer than the lower lens layers. As a result, small microlenses can be provided with longer focal lengths. The microlenses are arranged in arrays for use in imaging devices.

Abstract: A variety of structures and methods used to adjust the shape, radius and/or height of a microlens for a pixel array. The structures affect volume and surface force parameters during microlens formation. Exemplary microlens structures include a microlens frame, base, material, protrusions or a combination thereof to affect the shape, height and/or radius of the microlens. The frame, base and/or protrusions alter the microlens flow resulting from the heating of the microlens during fabrication such that a height or radius of the microlens can be controlled. The radius can be adjusted by the height differences between the microlens and frame. The bigger the difference, the smaller the radius will be.

Abstract: A microlens has a surface with an effective index of refraction close to the index of air to reduce reflection caused by change in indices of refraction from microlens to air. The microlens having an index of refraction approximately the same as that of air is obtained by providing a rough or bumpy lens-air surface on the microlens. Features protrude from the surface of a microlens to create the rough surface and preferably have a length of greater or equal to a wavelength of light and a width of less than a sub-wavelength of light, from about 1/10 to ¼ of the wavelength of light. The features may be of any suitable shape, including but not limited to triangular, cylindrical, rectangular, trapezoidal, or spherical and may be formed by a variety of suitable processes, including but not limited to mask and etching, lithography, spray-on beads, sputtering, and growing.

Abstract: A microlens includes a first light conductor having at least one concave recess, and a second light conductor in the recess. The curvature of the recess and the refractive indices of the light conductors cause incident light from the area of the microlens to be transmitted to a photosensor with a smaller area. In an array of microlenses, recesses may be separated to prevent crosstalk.

Abstract: Rebinning methods and arrangements are provided that significantly improve the 3D wavelet compression performance of the image based rendering data, such as, e.g., concentric mosaic image data. Through what is essentially a selective cutting and pasting process the image data is divided into stripes that are then used to form a set of multi-perspective panoramas. The rebinning process greatly improves the performance of the cross shot filtering, and thus improves the transform and coding efficiency of 3D wavelet codecs. While the region of support after rebinning may cease to be rectangular in some cases, a padding scheme and an arbitrary shape wavelet coder can be implemented to encode the result data volume of the smart rebinning. With an arbitrary shape wavelet codec, the rebinning outperforms MPEG-2 by 3.7 dB, outperforms direct 3D wavelet coder by 4.3 dB, and outperforms a reference block coder (RBC) by 3.2 dB on certain tested concentric mosaic image scenes. Hence, the rebinning process nearly quadruples the compression ratio for selected scenes. Additional methods and arrangements are provided that include selectively dividing the image data into slits and rebinning the slits into a huge 2D array, which is then compressed using conventional still image codecs, such as, JPEG.

Abstract: A semi-conductor based imager includes a microlens array having microlenses with modified focal characteristics. The microlenses are made of a microlens material, the melting properties of which are selectively modified to obtain different shapes after a reflow process. Selected microlenses, or portions of each microlens, are modified, by exposure to ultraviolet light, for example, to control the microlens shape produced by reflow melting. Controlling the microlens shape allows for modification of the focal characteristics of selected microlenses in the microlens array.

Abstract: A “PeerStreamer” provides receiver-driven peer-to-peer (P2P) media streaming for loosely coupled P2P networks. Peers in the network perform only simple operations, may cache all or part of the streaming media, do not collaborate with other peers, may be unreliable, and may drop offline or come online during any given streaming session. Clients in the network operate in real-time to coordinate peers, stream media from multiple peers, perform load balancing, handle online/offline states of peers, and perform decoding and rendering the streaming media. In one embodiment, the PeerStreamer uses high rate erasure resilient coding to allow multiple serving peers to hold partial media without conflict, such that clients simply retrieve fixed numbers of erasure coded blocks regardless of where and what specific blocks are retrieved. In another embodiment, the PeerStreamer uses embedded coded media to vary streaming bitrates according to available serving bandwidths and client queue status.

Abstract translation: “PeerStreamer”为松散耦合的P2P网络提供接收机驱动的对等（P2P）媒体流。 网络中的对等人只执行简单的操作，可以缓存全部或部分流媒体，不与其他对等体协作，可能不可靠，并且可能在任何给定的流媒体会话期间脱机或上线。 网络中的客户端实时协调对等体，从多个对等体流媒体，执行负载平衡，处理对等体的在线/离线状态，并执行解码和呈现流媒体。 在一个实施例中，PeerStreamer使用高速率擦除弹性编码来允许多个服务对等体保持部分媒体而没有冲突，使得客户端简单地检索固定数量的擦除编码块，而不管哪个特定块被检索。 在另一个实施例中，PeerStreamer使用嵌入式编码媒体根据可用的服务带宽和客户端队列状态改变流比特率。
