摘要:
An image processing device includes a corrector for performing an optical correction of correcting a distortion of an image by interpolating image data of the distorted picked-up image resulting from an optical characteristic of an image pickup section, and locally changing a resolution of the image; and a compressor for performing a dynamic range compression of compressing a dynamic range of the image data by extracting an illumination component from the image data based on a space frequency of the image, and compressing the extracted illumination component, wherein the compressor performs the dynamic range compression with respect to image data of an after-correction-image to be obtained after the optical correction is performed by the corrector.
