## Abstract

Provision is made for obtaining a high-quality image with noise, such as ringing, reduced. An image processing device includes an image correction means for applying image-shake correction processing to an input image; a correction-image characteristic detection means for detecting a characteristic of a correction image obtained through the image-shake correction processing; a first characteristic-determination means for outputting selection information, based on a characteristic-detected correction image obtained through detection of the characteristic of the correction image; and an image outputting means for outputting the input image or the correction image, based on the selection information. As a result, it is made possible to obtain a high-quality image with noise reduced.

## Claims

### Claim 1

An image processing device comprising:
an image correction unit for applying image-shake correction processing to an input image;
a correction-image characteristic detection unit for detecting a characteristic of a correction image obtained through the image-shake correction processing;
a first characteristic-determination unit for outputting selection information, based on a characteristic-detected correction image obtained through detection of the characteristic of the correction image;
a second selection-information changing unit for outputting changed information obtained by changing the selection information;
a first image outputting device for correcting and then outputting the correction image, based on the changed information;
a second image outputting device for correcting and then outputting the input image, based on the changed information;
and a third image outputting device for outputting an output image, based on the corrected input image and the corrected correction image.

### Claim 2 (depends on 1)

The image processing device according to claim 1, wherein the second selection-information changing unit changes selection information on a predetermined region that is a subject of processing, with reference to selection information on a predetermined region other than the subject of processing.

### Claim 3 (depends on 2)

The image processing device according to claim 2, wherein the second selection-information changing unit performs lowpass-filter processing.

### Claim 4

An image processing method comprising:
an image correction step of applying image-shake correction processing to an input image;
a correction-image characteristic detection step of detecting a characteristic of a correction image obtained through the image-shake correction processing;
a first characteristic-determination step of outputting selection information, based on a characteristic-detected correction image obtained through detection of the characteristic of the correction image;
a second selection-information changing step of outputting changed information obtained by changing the selection information;
a first image outputting step of correcting and then outputting the correction image, based on the changed information;
a second image outputting step of correcting and then outputting the input image, based on the changed information;
and a third image outputting step of outputting an output image, based on the corrected input image and the corrected correction image.
