Abstract: An estimated noise shape estimated to be included in the signal to be corrected is calculated based on a calibration signal including a noise correlating with the noise of the signal to be corrected so as to correct a noise of a signal to be corrected. A correction value of a noise shape is generated by attenuating an amplitude of the estimated noise shape, and the noise of the signal to be corrected is corrected by using the correction value of the noise shape thus generated.

Abstract: An image processing apparatus includes an image obtaining unit, a color shift detecting unit, a controlling unit, and a correction amount calculating unit. The image obtaining unit obtains image data. The color shift detecting unit detects color shifts of this image data. The controlling unit determines fitting reliability of the color shift detection result and selects a magnification chromatic aberration model suitable for color shift fitting according to the reliability. The correction amount calculating unit fits the magnification chromatic aberration model selected by the controlling unit to the color shift detection result and obtains correction amounts of the magnification chromatic aberration for the image data.

The detecting section detects the color shift amount by calculating the correlation between two color components included in the RAW data and determines the chromatic aberration of magnification of the optical system used for capturing the image from the color shift amount.

Abstract: An image processing device performs image processing to an image represented by a plurality of color component planes and includes a correction unit and an erroneous correction detection unit. The correction unit corrects a color shift in the image. The erroneous correction detection unit judges that the correction unit has made an erroneous correction by comparing the images before and after the correction. More preferably, the erroneous correction detection unit judges the erroneous correction when a chrominance of a portion to be processed of the image after the correction is not within an allowable range which is set using the image before the correction as a reference.
