Abstract
A system and a method for adjusting contrast and brightness in an image, e.g., an ultrasound image. The contrast and brightness are adjusted by processing global pixel intensity data to form a set of data representing a histogram. An algorithm is then employed to filter the pixel intensity values as a function of certain characteristics of the histogram data. The algorithm is designed to enhance contrast and brightness without affecting the near-field region in the ultrasound image. The filtering operations may be performed by a dedicated processor or by a fast general-purpose computer.
