Ip is optimized for high contrast resolution and good tissue differentiation, and ID is optimized for high detail resolution and the display of fine structural details. Ip and ID are applied as addressing inputs to a look-up table that provides an output image signal IO that combines both detail resolution of ID and contrast resolution of Ip. IO can display detail resolution as brightness and contrast resolution as color. IO can also be formed as a weighted combination or sum of Ip and ID. | |
