In this study we propose an endoscopic image enhancement technique named dynamic band imaging (DBI) which temporally changes color conversion matrix. DBI is based on the estimation of multi-spectral band images to enhance the endoscopic color images in order to distinguish the slight color difference of early-stage cancer more clearly. Since this method can be implemented by only using software approach, it is easy to upgrade the devices whereas narrow band technique requires hardware upgrading. From the results of fundamental analysis by subjective evaluations, DBI represents the effectiveness for image enhancement in comparison with the typical still image evaluation. Besides we have developed a user interface to determine six parameters of this method easily. By using this device, appropriate parameters for practical endoscopic diagnosis have been obtained. DBI is found as the new effective method to enhance color endoscopic images. |
