ABSTRACT:
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 detects halation of a predetermined level or higher in an image represented by a signal obtained by an imaging device, based on the signal. Light amount adjustment means decreases an amount of light emitted from illumination means to cause the halation to become a predetermined level or lower. Luminance conversion means 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.
