摘要： Techniques for image sensor pixel correction are described. In one embodiment, for example, an apparatus may comprise a processor circuit and an imaging management module, and the imaging management module may be operable by the processor circuit to determine an intensity value for a pixel in an image sensor pixel array, determine a pixel intensity deviation for the pixel comprising a difference between the intensity value for the pixel and a composite intensity value for a pixel neighborhood of the pixel, determine a pixel correction threshold for the pixel, and when the pixel intensity deviation exceeds the pixel correction threshold, determine a corrected intensity value for the pixel. Other embodiments are described and claimed.

摘要： A method for imaging includes receiving an input image that includes a matrix of pixels (32) having input pixel values. The input pixel values are processed so as to detect a region of saturation in the input image. A first image filtering operation is applied to the input pixel values of at least the pixels that are outside the region of saturation, so as to generate first filtered pixel values. A second image filtering operation is applied to the input pixel values of at least the pixels that are within the region of saturation, so as to generate second filtered pixel value. An enhanced output image is generated by stitching together the first and second filtered pixel values.
