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.

Abstract: An image processing device includes an extracting part and a prediction part. The extracting part extracts an unsaturated area, in which pixel values are not saturated, and a saturated area, in which pixel values are saturated, from image data that is captured by an imaging device and that shows an image including a plurality of pixels. The prediction part predicts a pixel value of a pixel of interest in the saturated area based on pixel values of a plurality of border pixels in a border area, the border area being located in the unsaturated area and bordering the saturated area.
