IMAGE PROCESSING DEVICE, METHOD FOR OPERATING THE SAME, AND ENDOSCOPE SYSTEM

摘要

First RGB image signals are subjected to an input process. First color information is obtained from the first RGB image signals. Second color information is obtained by a selective expansion processing in which color ranges except a first color range are moved in a feature space formed by the first color information, the first color information that represents each object in a body cavity being distributed in the each color range. The second color information is converted to second RGB signals. A red display signal, a green display signal and a blue display signal are obtained by applying a pseudo-color display process to the second RGB signals.

主权项

1. An image processing device comprising:
an input processor configured to perform an input process of a first red signal, a first green signal and a first blue signal; a color information obtaining processor configured to obtain first color information from the first red signal, the first green signal and the first blue signal; an expansion processor configured to obtain second color information by a selective expansion processing in which color ranges except a first color range are moved in a feature space formed by the first color information, the first color information that represents each object in a body cavity being distributed in the each color range; an RGB signal converter configured to convert the second color information to a second red signal, a second green signal and a second blue signal; and a pseudo-color display processor configured to obtain a red display signal, a green display signal and a blue display signal by applying a pseudo-color display process to the second red signal, the second green signal and the second blue signal.
