An image processing device, method and program in which a feature point derivation unit derives a plurality of characteristic points in an input moving image. A tracking subject feature point setting unit sets a feature point within a tracking subject, from the characteristic points. A background feature point setting unit sets a group of background feature points from the characteristic points. The background feature points are not located within the tracking subject. A motion detection unit detects movement over time of the background feature points. A clip area setting unit sets a size and a position of a clip area of an image to be employed which includes the feature point within the tracking subject, on the basis of the movement of the feature point within the tracking subject and the movement of the background feature points, when the motion detection unit detects movement of the background feature points.

An image processing device comprises: a tracking area setting unit that sets a tracking area in an input moving image obtained by photographing an object; a following feature point setting unit that detects a feature point that exhibits a motion in correlation with the motion of the tracking area and sets the detected feature point as a following feature point; a motion detection unit that detects movement over time of the following feature point within the input image; and a clip area setting unit that sets a clip area of an image to be employed when a partial image including the tracking area is clipped out of the input image for either recording or displaying or both recording and displaying, and that sets a size and a position of the clip area on the basis of a motion detection result obtained by the motion detection unit.

In a method of coding light ray information including information about a position on a predetermined surface and information about an incident angle to the surface when a ray of light from a subject enters the surface, the light ray information is divided into two or more processing unit blocks. In a first coding process, coding are executed for each of the two or more processing unit blocks, and first block unit information composing first image information about the subject is obtained. In a second coding process, coding are executed for each of the two or more processing unit block, and second block unit information composing second image information different types from the first image information is obtained.

Coding method, electronic camera, recording medium storing coded program, and decoding method

In a decoding method for decoding coded light ray information, coded first image information and coded second image information different from the first image information are decoded. The first image information and the second image information are obtained in taking a subject. The light ray information is generated based on the decoded first and second image information. Image information corresponding to a first focus value is generated and stored in a storage medium, based on the generated light ray information. An image is displayed based on the image information corresponding to the first focus value. Image information corresponding to a second focus value different from the first focus value is generated and stored in the storage medium, based on the generated light ray information. The image information corresponding to the second focus value is generated and stored, while the image is displayed or before the image is displayed.

Target pixel blocks are picked up from a target image selected from a plurality of images picked up by an imaging device, motion vectors of these target pixel blocks are calculated between two images, and affine transformation coefficients for blur correction is calculated based on the motion vectors. Weighting coefficients are set for target pixel blocks based on a confidence level of the calculated motion vectors with respect to the image blur. For example, motion vectors in peripheral portion of the image is usually large in size, so that the confidence level of these may be enhanced.

An image capturing device and a blurring correction method in which an imaging unit or a blurring correction optical system is driven to correct blurring in response to an output of a vibration detecting sensor. In such blurring correction, when a driving mechanism has a frictionally connected section, the blurring correction impairs an image at a time when an impact is generated. Therefore, an impact detecting section is disposed, and the blurring correction is not performed when the impact detecting section detects the impact.
