Abstract: An image processing apparatus including a processor comprising hardware. The processor being configured to: divide an imaging signal that is obtained by capturing an image of an inside of a subject into a first base component and a detail component, the first base component corresponding to an illumination component of an object, the detail component corresponding to a reflectance component of the object; generate a second base component by performing a color enhancement process on the first base component for increasing color gradation in a predetermined color space; and synthesize the second base component and the detail component to output a synthesized signal. Where the color enhancement process is an enhancement processing on the first base component for extending a color distribution range of at least one component of an L component, an a component, and a b component in a Lab color space.

Abstract: An image signal processing device includes: a base component extractor that generates an original base component signal; a base component adjuster that generates a first base component signal by performing weighted average processing; a detail component extractor that generates a first detail component signal based on the first base component signal; a relative emphasizer that outputs a second base component signal and a second detail component signal by relatively emphasizing the first detail component signal to the first base component signal; a combiner that generates a combined image signal by combining the second base component signal and the second detail component signal; and a storage that stores control parameters regarding similarity between the image signal and the first base component signal. The base component adjuster generates the first base component signal by performing the weighted average processing by using a weight coefficient determined in accordance with selected control parameter.
