Title:
PROCESSOR DEVICE AND METHOD FOR OPERATING SAME, AND ENDOSCOPIC SYSTEM AND METHOD FOR OPERATING SAME
Document Type and Number:
WIPO Patent Application WO/2016/158276
Kind Code:
A1
Abstract:
Provided are: a processor device capable of accurately calculating oxygen saturation in conditions where a yellow pigment or the like is present in the observation target; a method for operating the same; an endoscopic system; and a method for operating the same. An image signal acquisition unit 50 obtains a first image signal corresponding to a first wavelength band, a second image signal corresponding to a second wavelength band, a third image signal corresponding to a third wavelength band, and a fourth image signal corresponding to a fourth wavelength band. A correlation storage unit 72 stores the correlation between oxygen saturation and a first calculated value obtained from a specific calculation based on the second image signal, the third image signal, and the fourth image signal. A correlation correction unit 62 calculates a correlation correction amount on the basis of the first image signal, the second image signal, the third image signal, and the fourth image signal, and corrects the correlation on the basis of the correction amount.
