ABSTRACT:
A method of correcting a digital image comprises the steps of removing unrepresentative pixels, measuring the mean levels of the remaining pixels for each channel, determining an aim mean for each channel from the measured aim mean, determining a correction level, calculating a power law correction for each channel from the aim mean and the correction level and applying the power law correction to the input image to give a corrected output image.
