Abstract

An endoscope video processing system applies a blooming control feature to image frames of video data signals generated by viewing elements in the endoscope tip. A reduced digital gain is applied to a luminance (Y) component of the video data signal to generate an attenuated signal. An average luminance value of pixels neighboring a pixel of the attenuated signal is calculated and a function of the average luminance value is determined to generate a smoothly transitioning digital gain. The smoothly transitioning digital gain is conditioned using weights to generate a customizable digital gain, and the customizable digital gain is applied to the attenuated signal. This Local Blooming Control (LBC) facilitates a higher luminance digital gain in darker portions while maintaining a low or no luminance digital gain in brighter portions, within the same image frame.
