Assignee:

ESS Technology, Inc. - Fremont CA

International Classification:

H04N 9/64

US Classification:

348246

Abstract:

An image processing method and apparatus is described for processing a signal from a monochrome or color sensor that may be subject to pixel defects or blemishes. Without prior knowledge of any pixel defects, the processing method examines each pixel value and its neighboring pixel values. A number of tests are applied to the set of pixel values to determine whether the underlying pixel is defective. If the underlying pixel is determined to be defective, the pixel value is replaced by an estimate value derived from the values of its neighboring pixels. Otherwise, the pixel value remains intact.

International Classification:

H04N 7/12

US Classification:

37524003

Abstract:

A method for determining quantization numbers for each macro block in one video segment having a prescribed capacity is disclosed. The quantization numbers determine how much data will be preserved for that macro block. The method begins by determining a level of complexity for each macro block. Next, initial quantization numbers are chosen for the macro blocks by choosing the largest values possible without exceeding the prescribed capacity of the video segment. Final quantization numbers are selected based on respective ones of the initial quantization numbers proportioned according to the level of complexity for that macro block. The final quantization numbers may be increased or decreased so that the capacity of the video segment is maximized but not exceeded.

US Classification:

370413, 370503, 370429, 713400

Abstract:

A system for reducing clock speed and power consumption in a network chip. The system has a core that transmits and receives signals at a first clock speed. A receive buffer is in communication with the core and configured to transmit the signals to the core at the first clock speed. A transmit buffer is in communication with the core and configured to receive signals from the core at the first clock speed. A sync is configured to receive signals in the receive buffer at a second clock speed and to transmit the signals from the transmit buffer at the second clock speed. The sync is in communication with the transmit buffer and the receive buffer.

Inventors:

Michael Chang - San Jose CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

G11B 5/596

US Classification:

360 7809

Abstract:

A controller includes a combining module that generates a total control signal for the drive device of a disk drive by combining a feedback control signal and a feedforward control signal. A feedback control module generates the feedback control signal in response to at least one state of the drive device. A feedforward control module generates the feedforward control signal based on a smoothing function and a feedforward control function. The smoothing function is determined by evaluating a plurality of candidate smoothing functions by determining a smoothness factor associated with the control signal that results from each of the plurality of candidate smoothing functions, and selecting the smoothing function as one of the plurality of candidate smoothing functions, based on the smoothness factor.

US Classification:

360 75, 360 7704, 318560

Abstract:

A controller is disclosed that can be used in controlling a drive device of a disk drive, or other systems, in the presence of sinusoidal disturbances. The controller includes a calibration module that generates a plurality of reference states for a reference region of a disk of the disk drive. An initialization state generation module generates a plurality of initialization states for at least one other region of the disk as a function of the plurality of reference states, a displacement between the other regions of the disk and the reference region of the disk, and a reference state transition matrix. A control module generates a control signal for the drive device based on the plurality of initialization states.
