摘要： The sharpness of an image obtained by an endoscope is adjusted. A sharpness enhancement amount is determined for each pixel based on the value of each pixel which forms a luminance distribution image. Further, a portion contributing to adjustment of brightness and a portion contributing to adjustment of saturation in the sharpness enhancement amount are determined for each pixel of the image so that the sum thereof is equal to the sharpness enhancement amount. Then, an adjustment value of saturation, which is obtained by weighting the value of each pixel of the image based on the portion contributing to saturation, and an adjustment value of brightness, which is obtained by weighting the value of each pixel of the luminance distribution image, which corresponds to each pixel of the image, based on the portion contributing to brightness, are added to the value of each pixel of the image.

摘要： 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.
