Endoscope apparatus and deterioration detection method of polarization element of endoscope

摘要

An endoscope apparatus includes a flash memory that stores a reference value of a color balance adjustment value of an endoscopic image of an endoscope that picks up an object through a polarizer. The endoscope calculates, from the reference value and the color balance adjustment value of the endoscope after elapse of a predetermined time period, an amount of change in the color balance adjustment value; judges whether or not the calculated amount of change is equal to or larger than a predetermined threshold; and, when the amount of change is equal to or larger than the predetermined threshold, outputs a predetermined output.

主权项

1. An endoscope apparatus comprising:
a storage section that stores a reference value, which is a color balance adjustment value at a time of adjusting an endoscopic image obtained from an endoscope to be of predetermined color balance, in the endoscope that picks up an object through a polarizer; an amount-of-change calculating section that calculates, from the reference value stored in the storage section and the color balance adjustment value at the time of adjusting the endoscopic image after elapse of a predetermined time period to be of the predetermined color balance, an amount of change in the color balance adjustment value; a judgment section that judges whether or not the amount of change calculated at the amount-of-change calculating section is equal to or larger than a predetermined threshold; and an output section that performs a predetermined output when it is judged at the judgment section that the amount of change is equal to or larger than the predetermined threshold.
