  • Patent number: 7020353
    Abstract: In one embodiment, an imager has an array of photodetectors, each of which accumulates charge during an integration period as a result of light detected during the integration period, the array having a charge capacity which increases during the integration period. A charge capacity controller coupled to the imager adjusts how the imager increases the charge capacity of the array based upon the brightness distribution detected by the imager during at least one previous integration period.

  • Patent number: 7005708
    Abstract: An electrostatic discharge (ESD) MOS transistor including a plurality of interleaved fingers, where the MOS transistor is formed in an I/O periphery of and integrated circuit (IC) for providing ESD protection for the IC. The MOS transistor includes a P-substrate and a Pwell disposed over the P-substrate. The plurality of interleaved fingers each include an N+ source region, an N+ drain region, and a gate region formed over a channel region disposed between the source and drain regions. Each source and drain includes a row of contacts that is shared by an adjacent finger, wherein each contact hole in each contact row has a distance to the gate region defined under minimum design rules for core functional elements of the IC. The Pwell forms a common parasitic bipolar junction transistor base for contemporaneously triggering each finger of the MOS transistor during an ESD event.

  • Patent number: 6968494
    Abstract: A method and apparatus for transmitting an input data signal over an information channel. The input data signal comprises a sequence of data blocks. A puncture coded signal is generated for each data block in the sequence of data blocks. The total number of bits in the puncture coded signal is equal to the number of bits in a particular data block plus additional error correcting bits used to perform error correction at a receiver. The number of error correcting bits is adaptively adjusted for each data block in response to a channel quality measure for the information channel.

  • Patent number: 6885757
    Abstract: A low-frequency, temporally asymmetric watermark carrier decreases in luminance in a substantially monotonic manner more slowly than it increases in luminance in a substantially monotonic manner. This allows the carrier to be embedded, e.g., in a video work, in a manner that renders the resultant watermark virtually invisible to the human eye. Moreover, the resultant watermark is substantially resistant to common pirating techniques in which high-frequency visual content (e.g., including watermark data) tends to be filtered out by piracy processing.

  • Patent number: 6826292
    Abstract: A system that tracks one or more moving objects in a sequence of video images employs a dynamic layer representation to represent the objects that are being tracked. The system concurrently estimates three components of the dynamic layer representation—layer segmentation, motion, and appearance—over time in a maximum a posteriori (MAP) framework. In order to enforce a global shape constraint and to maintain the layer segmentation over time, the subject invention imposes a prior constraint on parametric segmentation. In addition, the system uses a generalized Expectation-Maximization (EM) algorithm to compute an optimal solution. The system uses an object state that consists of representations of motion, appearance and ownership masks. The system applies a constant appearance model across multiple images in the video stream.

  • Patent number: 6802313
    Abstract: Apparatus and a concomitant method for electrostatically depositing select doses of medicament powder at select locations on a substrate. Specifically, the apparatus contains a charged particle emitter for generating charged particles that charge a predefined region of a substrate and a charge accumulation control circuit for computing the amount of charge accumulated upon the substrate and deactivating the emitter when a selected quantity of charge has accumulated. Additionally, a triboelectric charging apparatus charges the medicament powder and forms a charged medicament cloud proximate the charged region of the substrate. The medicament particles within the medicament cloud electrostatically adhere to the charged region. The quantity of charge accumulated on the substrate at the predefined region and the charge-to-mass ratio of the medicament powder in the cloud control the amount (dose) of medicament deposited and retained by the substrate.

  • Patent number: 6785289
    Abstract: A method and concomitant apparatus for incorporating one or more relatively low bitrate information streams (e.g., MPEG) into a relatively high bitrate information stream (e.g., SDTI) in a manner aligning low bitrate sub-stream splice entrance points and splice exit points within the frame boundaries of the high bitrate information stream. In this manner, the splicing of the relatively high bitrate information stream at appropriate In Frames and Out Frames will provide relatively seamless splicing of information sub-streams. The packing and unpacking methods are implemented such that the temporal offset between elementary streams carried within relatively low bitrate information stream is removed, i.e., the elementary streams are synchronized.

  • Patent number: 6785338
    Abstract: Compression-related information is used to constrain the selection and control of video imagery and content used to produce one or more uncompressed video streams for subsequent compression processing. Rather than taking an uncompressed video stream “as is” for compression processing, characteristics of compression processing are taken into consideration during the video production stage when the uncompressed video stream is generated. Different types of constraints include “intra-frame” constraints that constrain video content within a frame of a video stream, “inter-frame” constraints that constrain video content from frame to frame within a video stream, and “inter-stream” constraints that constrain video content across different video streams. Two or more different constraints and two or more different types of constraints may be applied simultaneously. The compression-related information may be “static” (e.g.

  • Patent number: 6775325
    Abstract: An apparatus and method for changing the bitrate of an encoded bitstream in a compressed domain, i.e., a domain where the input image is still represented by transform coefficients, e.g., DCT coefficients or wavelet coefficients is disclosed. The bitrate of the encoded bitstream is changed by applying a different quantization scale directly to the transform coefficients of the encoded bitstream. The requantization error or distortion introduced by the requantization process is addressed by propagating the requantization error to the following frame.

  • Patent number: 6771795
    Abstract: A channel is inserted into a sequence of frames for an image, by varying one or more display characteristics of the resulting image across the display. The watermark and other data channel may be employed to watermark the video signal, and the watermark may correspond to the presence of the channel or may be data in accordance with watermark information carried within the channel. For most display devices, display variations are minimized during the design process, but human viewers may still tolerate and accept subtle variations in a displayed image. For exemplary embodiments in accordance with the present invention, slightly changing one or more display characteristics from center-to-side in accordance with watermark information allows for watermarking of the image since viewers may not be aware that display characteristics are changing. For example, a tapering function may be used in a transmitter to vary one or more color components of the video signal representing the image.

  • Patent number: 6771825
    Abstract: In predictive encoders that support both intra-frame and inter-frame coding, the coding of intermediate dissolve frames (i.e., those falling between the first and last dissolve frames) is restricted, such that either (1) no intermediate dissolve frame is coded as an anchor frame (e.g., MPEG I or P frame) or (2) only a specific number of frames at specific locations within the dissolve are encoded as anchor frames. In certain MPEG implementations, all intermediate dissolve frames are coded as B frames, while the first and last frames are coded as anchor frames (e.g., I or P frames). In other implementations, particular intermediate dissolve frames may be coded as anchor frames with the other intermediate frames coded as B frames. The present invention can provide improved coding results in terms of both bit rate and video quality by avoiding the accumulation of predication errors that can otherwise occur when fixed GOP patterns are applied during dissolves.
