Abstract
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.
