Abstract:
There is provided an image processing device including a motion compensation section which compensates motion between a target image and a reference image, an image compositing section which generates a composited image by compositing the target image and the reference image, the motion therebetween having been compensated, and a spatial filtering section which performs spatial filtering of the composited image. The spatial filtering section may perform spatial filtering of the composited image by using an ε-filter.

Abstract:
An image processing apparatus includes: an image processing section adapted to calculate a motion vector of an image signal between a plurality of frames; a first control section adapted to programmably control the image processing section to execute motion detection; and a second control section adapted to control the first image processing section in a processing state determined in advance to execute motion detection.
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.
