摘要： A method of removing streaks from multi-band digital images is presented in which a multi-band image is transformed to an advantageous spectral space, in which a streak removal operation is applied to the image in the advantageous spectral space. The streak removal operation is a method of removing columnar streaks from a multi-band digital image of the type in which it is assumed that pixels in a predetermined spatial and spectral region near a given pixel are strongly related to each other and employing gain and offset values to compute streak removal information, a test is performed for a strong relation between the pixels in a predetermined region spatially and spectrally near a given pixel and streak removal information is computed only if such a strong relationship exists, whereby image content that does not extend the full length of the image in the column direction will not be interpreted as a streak.

摘要： In a method for imaging using multiple apertures, the present invention uses a wavefront sensor, a phase sensor, and an image processor to construct a high-resolution image without using complex relay optics. A wavefront sensor collects information that allows the wavefront from each aperture to be reconstructed and a phase sensor collects information regarding the relative phase difference between the apertures. An image processor uses the information collected from the phase sensor to correct the phase differences between the apertures, reconstruct the wavefronts from the wavefront sensor data, then coherently sums the wavefronts from each aperture to form a high-resolution image that corresponds to a synthesized aperture that is larger than any of the individual apertures.

摘要： A method and application specific integrated circuit for determining focus for an image capture system using scene content within an image, including the steps of: acquiring, from the image, image data having different focus positions; dividing the image data into sub-images; calculating a sub-image sharpness value for each sub-image; calculating an image sharpness value for each focus position using the sub-image sharpness values; plotting the sharpness values versus the focus position; fitting a curve to the plot of the image sharpness values versus the focus position, wherein the curve has a peak sharpness value; and determining the focus of the image capture system from a point on the curve.
