摘要： A weighted sum of a set of component filters is used to effectively apply different “composite” FIR filters to compensate for aberrations resulting from different opto-mechanical settings. The FIR filters are “composite” in the sense that they are a weighted sum of the set of component filters. In one approach, the aberrations vary as a function of the opto-mechanical setting, and the opto-mechanical setting is used to determine the weights of the different component filters.

摘要： A spatially-varying sharpening filter and a color registration module compensate for significant lateral color in poorly corrected optics. In one aspect, a color imaging system includes image-forming optics, a sensor array and a processing module. The processing module includes a color registration module and a spatially-varying sharpening filter. The image-forming optics suffers from lateral chromatic aberration. The sensor array captures color pixels of the chromatically aberrated optical image. The spatially-varying sharpening filter sharpens the image (e.g., reduces the blurring caused by lateral color), and the color registration module realigns different color channels of the image.

摘要： A method and system for high-speed and low-complexity geometric transformation of signals are described. In one embodiment, the system comprises an input patch consisting of a window of pixels from an input image. The system may further comprise a transformation selector to generate control data to control a geometric transformation mapping based on the location of a current pixel being processed. In one embodiment, the system may also comprise a hardware geometric transform engine to perform a geometric transformation mapping by switching on one path through the geometric transform engine from an input window to an output pixel using the control data. In one embodiment, the system may further comprise an interpolator to generate interpolated geometric transformation mappings using the control data and multiple outputs from the geometric transform engine by switching on multiple paths from an input window.

摘要： A class of imaging systems in which the imaging optics, the sensor array and the image processing are related by three parameters: W040 the amount of third order spherical aberration, U the undersampling factor defined as the ratio of the Nyquist frequency of the sensor array divided by the diffraction-limited frequency of the imaging optics, and N the number of rows in the FIR implementation of the image processing. In one aspect, W040 is between approximately 2 and 8 waves, U is between approximately 0.05 and 0.30, and N satisfies an equation that defines the acceptable range of N as a function solely of W040 and U.
