1. A method for adjusting image processing parameters for an image captured by a digital camera comprising: for every image captured by the camera; automatically generating image statistics for the entire captured image after the image has been captured; generating an estimated camera sensitivity as a function of a preset ISO setting in the camera and the image statistics of the captured image; automatically adjusting ISO-dependent image processing parameters for the captured image captured by the camera as a function of the generated estimated camera sensitivity without employing data from additionally captured images; and automatically processing the captured image using the adjusted parameters to create an adjusted image.
