TXI can enhance brightness selectively in dark areas of endoscopic images and can enhance subtle tissue differences such as slight morphological and/or color changes over conventional enhancement methods including structure enhancement and color enhancement. Comparing TXI with conventional white light imaging (WLI) for real-world image processing, TXI can achieve significant image enhancement with characteristics of WLI appearance while preventing over-enhancement observed in other methods. TXI has two modes, mode1 and mode 2. Enhancement of brightness and texture is similar in both modes. The enhancement of color contrast of mode1 is superior to that of mode 2 in accordance with the color enhancement of the mode1 algorithm; however, the naturalness in mode 2 is better than that of mode 1. Overall, TXI provides a balance of improving image features important for the physician searching for abnormalities (selective increase in brightness, greater color separation, and texture enhancement) while minimizing gross changes that may negatively impact familiarity (naturalness).
