methods for improving video images by making real - time gamma correction adjustments to such images are described . more particularly , gamma correction adjustments may be optimized for each individual frame of a video image by first segregating the pixels of an image according to brightness . the segregated pixels may then be used in computing weighting calculations , which modify the transfer functions used for image display . in some embodiments , the video signal may be conditioned between the standard gamma curve and the s - shaped gamma curve used in mapping video signal input to intensity output . in this manner , frame - to - frame gamma correction adjustments can be made , thereby optimizing the resulting image . related systems for making frame - to - frame gamma correction adjustments are also described .
