Abstract: An image processing device includes a memory and a processor configured to calculate a reference black level and a reference illumination light component based on pixel values of peripheral pixels located around a target pixel for image processing using image data acquired by an imaging device, correct a black level of the target pixels based on the reference black level calculated by the processor, and perform a tone correction of the target pixels with the black level corrected based on the reference illumination light component calculated by the processor. Accordingly, even when a large gain is applied to a dark portion of an image in a local tone correction, it is possible to generate an image with high visibility in which an occurrence of raised black levels is suppressed.
