Claim One:
1. A method, comprising: accessing at least a portion of a digital raw image frame captured by a digital image sensor; de-noising the accessed at least a portion of the digital raw image frame without substantially modifying defective pixel values when present; and in response to determining that at least one image frame pixel in the de-noised at least a portion of the digital raw image frame has a defective pixel value: detecting the locations of each of the at least one image frame pixel having a defective pixel value; and correcting each defective pixel value in each detected location in one of the de-noised at least a portion of the digital raw image frame and the originally accessed at least a portion of the digital raw image frame, wherein the determining comprises performing the following for each color channel: determining one of a first maximum pixel value or a first minimum pixel value of closest neighboring image frame pixels to a current image frame pixel; determining one of a second maximum pixel value or a second minimum value of closest and second closest neighboring image frame pixels of the current image frame pixel excluding the closest neighboring image frame pixel corresponding to the determined first maximum pixel value or the determined first minimum pixel value; and determining the current image frame pixel to have a defective pixel value upon a pixel value of the current image frame pixel being greater than a product value of (i) the first maximum value, the second maximum value, the first minimum value, or the second minimum value and (ii) a predetermined threshold value.
