<p>An image obtained by an electronic endoscope apparatus is changed to an image that is appropriate for observation with suppressed halation and fewer dark areas. Halation detection means (19) detects halation of a predetermined level or higher in an image represented by a signal obtained by an imaging device (11), based on the signal. Light amount adjustment means (19, 27, 28, 29, 30) decreases an amount of light emitted from illumination means (25, 15) to cause the halation to become a predetermined level or lower. Luminance conversion means (23, 24) processes the signal so as to generate a luminance conversion image wherein only a dark area having a predetermined luminance or lower in the image due to the decrease in the amount of the light is changed to have a higher luminance.</p> |
