System and method for automatic gain compensation based on image processing

摘要

There is provided an image processing system, which includes: a volume data processor for forming volume data based on image signals and setting at least one frame in the volume data; an AGC/LGC parameter setting unit for setting axial gain compensation (AGC) and lateral gain compensation (LGC) parameters based on the frame; a gain parameter setting unit for setting a gain parameter based on the frame; an amplifying unit for performing AGC/LGC upon image signals based on the AGC/LGC parameters and amplifying the image signals based on the gain parameter; a brightness adjusting unit for analyzing intensities of pixels included in the volume data formed based on the image signal performing the AGC/LGC and adjusting the gain, and adjusting brightness of the volume data based on the analysis result; and an image processor for forming images based on the frame and the volume data.
