## Abstract

There is provided an imaging device including a detection section which detects motion of the image processing device, a blend ratio calculation section which calculates a blend ratio of a first motion compensation image to a second motion compensation image, the first motion compensation image and the second motion compensation image being determined from a first motion vector and a second motion vector each indicating motion between frames, respectively, based on the motion of the image processing device detected by the detection section, a blend section which generates a motion compensation image by blending the first motion compensation image and the second motion compensation image in accordance with the blend ratio calculated by the blend ratio calculation section, and an addition section which adds the motion compensation image generated by the blend section to a target image.

## Claims

### Claim 1

An image processing device comprising:
a detection section which detects motion of the image processing device;
a blend ratio calculation section which calculates a blend ratio of a first motion compensation image to a second motion compensation image, the first motion compensation image and the second motion compensation image being determined from a first motion vector and a second motion vector each indicating motion between frames, respectively, based on the motion of the image processing device detected by the detection section;
a blend section which generates a motion compensation image by blending the first motion compensation image and the second motion compensation image in accordance with the blend ratio calculated by the blend ratio calculation section; and
an addition section which adds the motion compensation image generated by the blend section to a target image, wherein the detection section detects the motion of the image processing device by detecting connection of a fixing member to the image processing device.

### Claim 2 (depends on 1)

The image processing device according to claim 1,
wherein the second motion compensation image is a motion compensation image determined based on a frame obtained by being delayed one frame or more with respect to a frame used for determining the first motion compensation image.

### Claim 3 (depends on 1)

The image processing device according to claim 1,
wherein the first motion vector is a vector calculated for each block set within each frame.

wherein the second motion vector is a vector calculated for each frame.

### Claim 5 (depends on 1)

The image processing device according to claim 1,
wherein the detection section detects the motion of the image processing device by detecting movement of the image processing device.

### Claim 6

An image processing method comprising:
detecting motion of an image processing device by detecting connection of a fixing member to the image processing device;
calculating a blend ratio of a first motion compensation image to a second motion compensation image, the first motion compensation image and the second motion compensation image being determined from a first motion vector and a second motion vector each indicating motion between frames, respectively, based on the motion of the image processing device;
generating a motion compensation image by blending the first motion compensation image and the second motion compensation image in accordance with the blend ratio; and
adding the motion compensation image to a target image.

### Claim 7 (depends on 6)

The image processing method according to claim 6, wherein the second motion compensation image is a motion compensation image determined based on a frame obtained by being delayed one frame or more with respect to a frame used for determining the first motion compensation image.
