摘要： A demosaicing method for an input mosaic image includes: obtaining an input image, for each sub target pixel, estimating a main edge direction based on main color pixel values; determining the main edge direction by performing edge enhancement based on the input mosaic image; generating a main color demosaiced image by performing a main interpolation based on the main edge direction to generate interpolated main color pixel values corresponding to the sub target pixels; and generating a first sub color demosaiced image and a second sub color demosaiced image by performing a sub interpolation to generate interpolated first sub color pixel values and interpolated second sub color pixel values for the sub target pixels and for main target pixels corresponding to the main color pixel values.

摘要： A lens shading correction circuit includes an elliptical gain generation circuit configured to extract a position of a pixel and generate an elliptical gain value using elliptical gain parameters and the extracted position and a multiplier configured to output an output value by multiplying the elliptical gain value by a weight for the pixel. The lens shading correction circuit corrects the lens shading based on the first output value and a gain increment value.

摘要： Provided are image signal processing apparatuses and methods for operating the same. In an embodiment, the image signal processing apparatus is configured to receive, from an image sensor device, an input image. The apparatus is further configured to perform a binning and crop operation on the input image to generate a first image. The apparatus is further configured to perform a Bayer domain processing on the first image to generate a second image. The apparatus is further configured to perform RGB domain processing on the second image to generate a third image. The apparatus is further configured to perform YUV domain processing on the third image to generate an output image. The YUV domain processing comprises at least one of a spatial de-noising operation, a temporal de-noising operation, a motion compensation operation, a tone mapping operation, a detail enhance operation, and a sharpening operation.
