摘要： A forward interpolation approach is disclosed for enabling a second version of an image to be constructed from a first version of the image. According to one implementation, an input pixel from the first version of the image is forward mapped to the second version of the image to determine a set of candidate pixels that may be affected by the input pixel. Each candidate pixel is then backward mapped to the first version of the image to determine whether they are actually affected by the input pixel. For each candidate pixel that is actually affected by the input pixel, a pixel value is determined for that candidate pixel based at least in part upon the pixel value of the input pixel. By using this forward and backward mapping technique, forward interpolation can be implemented quickly and efficiently.

摘要： A forward interpolation approach is disclosed for enabling a second version of an image to be constructed from a first version of the image. According to one implementation, pixels from the first version of the image are mapped to pixels in the second version of the image, and pixel values are determined for the corresponding pixels in the second version of the image. In one implementation, the pixel mapping is performed using a lookup table and linear approximation. Performing the pixel mapping in this manner enables computations to be simplified and cost and gate count to be reduced.

摘要： An optical system can provides a distorted image of an object within a field of view onto sensing pixels of an image capturing device. The optical system can expand the image in a center of the field of view and compress the image in a periphery or introduce other distortion. The distortion intentionally introduced by the optical system is corrected when the sensing pixels are read to remove some or all of the distortion and thereby produce a “rectified” image. The pixels can be read along a trajectory corresponding to a curvature map of the distorted image to rectify distortions during pixel read out, rather than waiting until all or substantially all of the sensing pixels have been read. Sensor logic and/or algorithms can be used in removing the distortion.

摘要： A forward interpolation approach is disclosed for enabling a second version of an image to be constructed from a first version of the image. According to one implementation of the forward interpolation approach, pixels from the first version of the image are processed one row at a time. As the pixels in a row of pixels in the first version of the image are processed, they may cause pixel values on different rows of the second version of the image to be determined. Since the pixel values of the second version of the image are stored in output line buffers, this means that, at any particular point in time, there may be multiple partially filled output line buffers. It has been observed that the forward interpolation approach enables significant benefits (such as reduced storage requirements and reduced internal bandwidth and processing) to be achieved over a backward interpolation approach.

摘要： Techniques for detecting and addressing image flicker are disclosed. An imaging device that senses a distorted image and subsequently removes the distortion during processing can utilize an analysis module that obtains statistics indicative of image flicker prior to removing the distortion. An imaging device that features a diode for illuminating a field of view can utilize the diode as a photosensor to determine one or more flicker statistics to determine whether ambient lighting conditions are of the type that cause image flicker.

摘要： A method and apparatus for adjusting the effect of applying a kernel to a signal is provided. The adjustment may be based on the magnitude of an effect that a kernel matrix is intended to have on the signal matrix. The adjustments can be based on factors including, but not limited to, a signal-to-noise ratio of the signal data, properties of a device (e.g., lens) used to capture the signal data, or a metric that is derived based on an analysis of the signal data. Processing image data in accordance with an embodiment of the present invention is aimed at regaining lost contrast that may be due to properties of optics that are used to capture the image data.

摘要： A 9 pixel-by-9 pixel working window slides over an input Bayer image. For each such window, a demosaicing operation is performed. For each such window, corrective processing is performed relative to that window to produce relative differences for that window. For each such window for which relative differences have been produced, those relative differences are regulated. For each window, a maximum is found for that window's regulated relative differences; in one embodiment of the invention, this maximum is used to select which channel is sharp. For each window, the colors in that window are corrected based on the relative difference-based maximum found for that window. For each window, edge oversharpening is softened in order to avoid artifacts in the output image. The result is an output image in which axial chromatic aberrations have been corrected.
