Abstract: In an image taking apparatus, an imaging unit senses an image of a subject, and a face detection unit detects a face in the image sensed by the imaging unit. A motion detection unit detects an amount of face motion indicating an amount of shake of an area of the face detected by the face detection unit in the image sensed by the imaging unit and also detects an amount of background motion indicating an amount of shake of an area other than the face area. A shake correction unit corrects the shake of the image sensed by the imaging unit according to the amount of face motion and the amount of background motion detected by the motion detection unit.

Abstract: It is now possible to correct flicker without the risk of correcting flicker by error if a moving subject exists in the scene by using values detected in the past in order to prevent degradation of image quality from taking place. The integral value obtained by integrating an input video signal that includes a flicker component over not less than a horizontal period and the difference value between integral values of adjacent fields or frames is normalized. Then, the amplitude component and the phase component of the flicker component are estimated. A flicker coefficient for canceling the amplitude component and the phase component of the flicker component estimated is generated on the basis of the probability of being under the lighting of a fluorescent lamp. The flicker coefficient and the input video signal are computationally determined to obtain a video signal with a reduced flicker component.

Abstract: In an image pickup device, a controller includes a surplus area calculation unit to detect a surplus area for use in correcting camera shake based upon a size of an effective area on an image pickup surface and a size of an efficient area extracted in response to camera shake. Thus, this image pickup device can prevent a troublesome aspect in which camera shake correction reaches the correction end from occurring, even when a large camera shake that is beyond the surplus area occurs.

Abstract: An imaging apparatus is disclosed. The imaging apparatus includes an image capturing section, a motion detecting section, a reliability determining section, a shaking compensating section, and a filtering section. The image capturing section captures a plurality of images which chronologically differ. The motion detecting section detects motion of the plurality of images and generates motion information. The reliability determining section determines reliability of the motion information. The shaking compensating section compensates shaking which takes place among the plurality of images corresponding to the motion information. The filtering section filters an image which has been compensated for shaking by using a recursive filter. A characteristic of the filtering section is varied corresponding to the reliability of the motion information.
