  • Patent number: 7206002
    Abstract: An image processing apparatus includes a spatial filtering unit which applies spatial filtering to input image data to generate filtered image data such that the spatial filtering provides a broader dynamic range for outputs than for inputs, and a high-resolution conversion unit which interpolates the filtered image data in a first direction by an average of values of two pixels adjacent in the first direction, in a second direction perpendicular to the first direction by an average of values of two pixels adjacent in the second direction, and in a direction diagonal to the first and second directions by an average of four pixels surrounding a pixel of interest, thereby converting the filtered image data into high-resolution image data.

  • Patent number: 7176079
    Abstract: A method of fabricating a semiconductor device includes depositing a dielectric film and subjecting the dielectric film to a wet oxidation in a rapid thermal process chamber. The technique can be used, for example, in the formation of various elements in an integrated circuit, including gate dielectric films as well as capacitive elements. The tight temperature control provided by the RTP process allows the wet oxidation to be performed quickly so that the oxidizing species does not diffuse significantly through the dielectric film and diffuse into an underlying layer. In the case of capacitive elements, the technique also can help reduce the leakage current of the dielectric film without significantly reducing its capacitance.

  • Patent number: 7166879
    Abstract: A photogate-based photosensor for use in a CMOS imager exhibiting improved short wavelength light response. The photogate is formed of a thin conductive layer about 50 to 3000 Angstroms thick. The conductive layer may be a silicon layer, a layer of indium and/or tin oxide, or may be a stack having an indium and/or tin oxide layer over a silicon layer. The thin conductive layer of the photogate permits a greater amount of short wavelength light to pass through the photogate to reach the photosite in the substrate, and thereby increases the quantum efficiency of the photosensor for short wavelengths of light.

  • Patent number: 7163893
    Abstract: A high integrity, reliable liner is disclosed for a via in which a titanium aluminide layer is preformed as a lining within a via hole prior to deposition of other conductive materials within the via hole. The conductive materials deposited on the preformed titanium aluminide can be either a secondary barrier layer portion of the liner, such as a titanium compound layer, which in turn has a metal plug deposited thereon, or, alternatively, a metal plug directly deposited on the titanium aluminide layer. An important advantage achieved by the present invention is that a via is formed with a substantial elimination of void formation. The enhanced vias are useful in a wide variety of semiconductor devices, including SRAMS and DRAMs.

  • Patent number: 7116133
    Abstract: The present invention provides a clock signal input circuit that is able to provide inverse internal clock signals generated by the same input buffer as the address and data signals which exhibit reduced skew. When a skewed external noninverse clock signal and a corresponding external inverse clock signal are passed through respective reference voltage input buffers there is no reduction in skew between the two internal signals. In a preferred embodiment, the invention provides back to back inverters connected to both lines carrying the noninverted and inverted internal clock signals. The slower internal clock signal has an extra inverter driving it when it switches states and the faster internal clock signal has an extra inverter fighting it when it switches states. The skew of the two signals is reduced, allowing for faster operation of the integrated circuit and a reduction in misread data signals.

  • Patent number: 7116329
    Abstract: An image processing method is disclosed for more effectively displaying movements of an object composed of a plurality of polygons. The image processing method displays a moving object by displacing backward given vertices of polygons composing the moving object, imparting an afterimage representation that makes the object look as if it leaves a trail in the direction opposite to their direction of movement. This allows for display of movements of the object in a more emphasized manner and display of the moving object with richer expression.

  • Patent number: 7113384
    Abstract: A dynamic degaussing system includes a magnetic field sensor for generating a sensor signal in response to a sensed magnetic field. The magnetic sensor is coupled to a controller that produces an output signal based on the sensor signal. The controller may include feedforward and feedback control loops. The output signal of the controller controls a magnetic field generator which generates a magnetic field so as to attenuate the sensed magnetic field. According to one aspect of the invention, a vessel is provided with a reduced magnetic signature and a control system for controlling magnetic fields about a podded electric motor. The control system employs feed-forward and feedback control in tandem. The control system may be dynamically adapted to changing physical characteristics of the motor. Control signals are generated in response to sensed or predicted magnetic fields internal to, or external to, the motor.

  • Patent number: 7110598
    Abstract: An electronic imaging system operates as closely as possible to the cone spectral response space to obtain a human eye-like long, medium, short (LMS) wavelength response. An input image, for example, red-green-blue (RGB), is transformed to an LMS color space similar to the human long-, middle-, and short-wavelength cone receptor responses. Adaptation levels for each LMS component are calculated. The adaptation levels are then used to adjust the sensitivity of each LMS sensor response to obtain an LMS component image. The LMS component image then is transformed back to an RGB component image for further processing or display.

  • Patent number: 7105793
    Abstract: Embodiments of the invention provide pixel cells that allow both automatic light control and correlated double sampling operations. The pixel cell includes first and second photo-conversion devices that can be separately read out. For example, the second photo-conversion device can be the pixel cells' floating diffusion region, with an area and doping profile suitable for photo-conversion. An image sensor may include an array of pixel cells, some or all of which have two photo-conversion devices, and peripheral circuitry for reading out signals from the pixel cells. The image sensor's readout circuitry may monitor charge generated by the second photo-conversion devices to determine when to read out signals from the first photo-conversion devices.
