Abstract
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.
