Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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 o…
