Abstract

An image processing apparatus includes: an addition intensity calculation unit which calculates an addition intensity on the basis of a difference between first image data included in a plurality of pieces of image data obtained through sequential shooting and second image data included in the plurality of pieces of image data; and an addition processing unit which performs addition processing of the first image data and the second image data on the basis of the addition intensity.

Claims

1. An image processing apparatus comprising:

an addition intensity calculation unit which calculates an addition intensity on the basis of a difference between first image data included in a plurality of pieces of image data obtained through sequential shooting and second image data included in the plurality of pieces of image data; and

an addition processing unit which performs addition processing of the first image data and the second image data on the basis of the addition intensity.

2. The image processing apparatus according to claim 1,

wherein the first image data is image data based on first imaging in the sequential shooting,

the addition intensity calculation unit calculates an addition intensity on each piece of image data on the basis of a difference between the first image data and each piece of image data included in the plurality of pieces of image data excluding the first image data, and

the addition processing unit performs addition processing of the first image data and the plurality of pieces of image data excluding the first image data on the basis of the addition intensity on each piece of image data.

3. The image processing apparatus according to claim 2,

wherein the difference is detected on the basis of brightness detected in each multi-pattern photometric frame.

4. The image processing apparatus according to claim 1,

wherein the addition intensity calculation unit calculates the addition intensity on each piece of image data on the basis of focus information corresponding to each piece of image data.

5. The image processing apparatus according to claim 1,

wherein the addition intensity calculation unit calculates the addition intensity on the basis of an imaging scene when image data is taken.

6. The image processing apparatus according to claim 1,

wherein the addition processing unit performs addition processing of the plurality of pieces of image data in order of imaging in the sequential shooting, and when the addition intensity is smaller than a predetermined value, terminates subsequent addition processing.

7. An image processing method comprising:

calculating an addition intensity on the basis of a difference between first image data included in a plurality of pieces of image data obtained through sequential shooting and second image data included in the plurality of pieces of image data; and

performing addition processing of the first image data and the second image data on the basis of the addition intensity.

8. An image processing program which causes a computer to function as an image processing apparatus,

wherein the image processing apparatus includes

an addition intensity calculation unit which calculates an addition intensity on the basis of a difference between first image data included in a plurality of pieces of image data obtained through sequential shooting and second image data included in the plurality of pieces of image data, and

an addition processing unit which performs addition processing of the first image data and the second image data on the basis of the addition intensity.
