  • Correction of white balance deviation in a captured image
    Patent number: 8498031
    Abstract: A method is provided for correcting an image. At least some pixels in a captured image are scanned and there is selected each scanned pixel having at least one associated light intensity value greater than an intensity threshold value based on a comparison between the light intensity values for color indicators associated with the scanned pixel. Three correction information items are obtained by summing the light intensity values associated with the pixels selected by color indicator, and a correction of the white balance deviation affecting the captured image is determined based on the correction information items. A pixel is selected if both the difference between a mean light intensity value and a lowest light intensity value associated with the scanned pixel and the difference between a highest light intensity value and the mean light intensity value associated with the scanned pixel are less than a difference threshold value.
