摘要:
Image display systems and methods are provided. A plurality of pixel groups, each including a plurality of independent pixels, forms a display. A plurality of lenses (1251-N) forming an optical array and aligned along at least one axis (130), can be disposed proximate the display. Each of the plurality of lenses can provide a limited viewing arc (1501-N) for each of the plurality of independent pixels. A sample system can also include a detector (160) to detect the presence and location of a first user (165) and a second user (170) and logic (175), that when executed by a processor (180) coupled to the display, routes a first display signal (1451) based upon the viewing arc of a first portion of pixels; and routes a second display signal (1452) based upon the viewing arc of a second portion of pixels.

According to one embodiment, video data from a video transmitter (110) is received (420) at a network buffer (130). Information that pertains to a network buffer drain rate (14) of the network buffer (1q3) is monitored (430). The network buffer drain rate (140) is a rate that the video data is removed from the network buffer (130). The network buffer drain rate (140) is estimated (440) based on the monitored information. A transmission rate (120) that the video transmitter (110) transmits future video data is adjusted (450) to not exceed an allowed transmission rate (ATR) that is calculated based on the estimation of the network buffer drain rate (140).

摘要:
A method for generating a high-resolution image from a plurality of low-resolution images generated from quantized coefficients in the spatial frequency domain and the uncertainties in the quantized coefficients. The method generates a set of linear inequalities relating the quantized coefficients, the uncertainties therein, and the pixel values for the high-resolution image. Each linear inequality relates one of the quantized coefficients to a linear sum of the high-resolution pixel values. A high-resolution image whose pixels satisfy this set of inequalities is then generated
摘要:
A method and system for capturing analog video data and previewing still video images of the captured analog video data without converting the analog video data into digital image data. The system takes analog video data and converts the data into raw digitized video data. The raw digitized video data is stored in a memory until the data is selected for previewing. Once selected, the raw digitized video data is reconverted into analog video data that presents a still image of the desired data. The system is also able to discard unnecessary portions of the raw digitized video data and store only necessary portions of the raw digitized video data. Preferably, the video capture, preview, and storage technique is used in video printing. When used in video printing, the raw digitized video data is converted into digital image data using a software decoding process.
摘要:
A robust system, adaptive to motion estimation accuracy, for creating a high resolution image from a sequence of lower resolution motion images produces a mapping transformation for each low resolution image to map pixels in each low resolution image into locations in the high resolution image. A combined point spread function (PSF) is computed for each pixel in each lower resolution image employing the mapping transformations provided that they describe accurate motion vectors. The high resolution image is generated from the lower resolution images employing the combined PSF's by projection onto convex sets (POCS), where sets and associated projections are defined only for those pixels whose motion vector estimates are accurate.

摘要:
Compressed frames of a video with associated reduced information about an object are received. The video has unreduced information about an object moving with respect to boundaries that are fixed with in each frame of the video and the compressed frames have reduced information about the object moving with respect to the boundaries that are fixed with in each of the compressed frames. The reduced information has quantization error due to compression. An estimate of the unreduced information is created by transforming the reduced information into the estimate using computer implemented motion estimation. The estimate has less quantization error than the reduced information.
