Abstract
An image processing apparatus includes a processor including hardware. The processor is configured to: execute a first white balance adjustment on a first signal corresponding to multiple wavelength bands; generate a luminance signal from a second signal including an area having saturation caused by the first white balance adjustment; extract a detail component based on the first signal; and apply the detail component to the luminance signal to generate a corrected luminance signal.
