US 8,411,172 B2 · Imaging device and image processing apparatus

Abstract

An imaging device includes an imager, with which an optical image of an object scene is repetitively captured. A first movement detector detects, as to each of a plurality of object scene images according to a time series output from the imager, a movement of a first feature point between the object scene image and the object scene images immediately before, and a clipper performs clipping processing on each of the plurality of object scene images on the basis of the detection result. When a still image recording operation is performed, a CPU changes an exposure time of the imager in such a direction as to shorten the time, and a second movement detector detects a movement of a second feature point between the object scene image immediately after the recording operation (reference object scene image) and the three object scene images being successive thereto out of a plurality of object scene images, and an adder adds the respective three object scene images to the reference object scene image while displacing the same on the basis of the detection result.

Dependent claims

An image processing apparatus for performing image processing on a plurality of object scene images according to a time series that is output from an imager for repetitively capturing an optical image of an object scene, comprising:

an FPN corrector for performing FPN correction processing on said plurality of object scene images;
a movement detector for detecting a movement of a feature point among said plurality of object scene images;
a first clipper for performing clipping processing on each of said plurality of object scene images at a position based on the detection result by said movement detector;
an adder for performing adding processing of adding to each of said plurality of object scene images after said first clipper, one or plurality of object scene images temporally proximate to said object scene image;
a first determiner for repetitively determining whether or not the movement detected by said movement detector is above a threshold value;
and
a first controller for making said FPN corrector invalid when the determination result by said first determiner is affirmative and making said FPN corrector valid when the determination result by said first determiner is negative.

a movement detector for detecting a movement of a feature point among said plurality of object scene images;
a first clipper for performing clipping processing on each of said plurality of object scene images at a position based on the detection result by said movement detector;
and
an adder for performing adding processing of adding to each of said plurality of object scene images after said first clipper, one or plurality of object scene images temporally proximate to said object scene image, wherein
said adder includes a divider for dividing a pair of object scene images to be added with each other into common partial images, and a weighted adder for weighing the division result by said divider with a coefficient for each common partial image and adding the results to each other.
