摘要： An image processing method for subjecting captured-image data outputting from an image-capturing device to an optimization processing for appreciation to produce viewing image referred image data. The image processing method has the step of conducting a pre-processing before the optimization processing is carried out, wherein the pre-processing includes the transformation of the frequency characteristic of the captured-image data into the scene-referred frequency characteristic by removing the effect of a frequency characteristic specific to the image-capturing device from the frequency characteristic of the captured-image data.

摘要： In an image processing method for carrying out an image quality correction for correcting an image quality on each of a plurality of images in an image group to obtain corrected images, an image processing method includes the steps of carrying out a temporary image quality correction for correcting an image quality on each images in the image group to obtain a temporarily corrected image. A characteristic value representing an image quality for each temporarily corrected image is calculated and a target characteristic value is calculated so that dispersion of each characteristic value to the target characteristic value is minimized on the basis of the characteristic value of each temporarily corrected image. A correction value of each of the plurality of images in the image group which corrects the characteristic value thereof to the target characteristic value is obtained, and the image is corrected with the correction value.
