Abstract:
1. A method of content adaptive edge and detail enhancement for image processing comprising the steps of: receiving input image; applying LTI (Luminance Transient Improvement) to the image; applying CTI (Chrominance Transient Improvement) to the image; applying 2 dimensional peaking to the image; analyzing the image to determine the type of edge transitions present in the image; creating a first mask to differentiate between strong and soft transitions present in the image; blending the LTI/CTI and peaking modified images according to said first mask; creating a second mask to differentiate between flat and busy areas of the image; adjusting the gain of the peaking computation according to said second mask to reduce gain of the peaking computation for flat areas of the image; applying negative coring to flat areas present in the image according to said second mask; outputting the modified image.
