Image processing device, image processing method, and image pickup apparatus
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.
1. An image processing method, comprising:
a converting step of unifying multiple photoelectric conversion characteristics of image data of an image picked up by an image pickup section having multiple photoelectric conversion characteristics into a single photoelectric conversion characteristic; and
a correcting step of performing an optical correction of correcting a distortion of the image by interpolating the image data of the distorted picked-up image resulting from an optical characteristic of the image pickup section, and locally changing a resolution of the image, wherein
the converting step is performed before the correcting step.
