Abstract: A zoom lens barrel capable of attaining a higher photographing magnification by reducing spacing between lens groups in a telephoto state. A first lens group barrel holds a first lens group. A second lens group holding member supported by a third cam barrel holds a second lens group. A spring member urges the holding member toward the first lens group. Cam followers are formed at an opposite end of the holding member from the first lens group. Cam grooves for engagement with the cam followers are formed on the third cam barrel. When the holding member is urged by the spring member in a non-shooting region, each cam groove is brought into contact via one cam surface with the associated cam follower. In a shooting region, the cam groove is brought into contact with the cam follower via two cam surfaces.

Abstract: An image processing device that produces a restored image that gives people natural feeling when a shot image with longer exposure time on the way to image blurring due to hand jiggling or an end portion is restored. The image processing device comprises an image processing unit that produces a restored image approximated to an original image from an object image to be processed, which is fluctuated against the original image due to movement of an image shooting device during exposure. The image processing unit produces the restored image while making the restored image correspond to a position having the longest exposure time for an object image to be processed.

Abstract: One of a plurality of color components which form pixels in an image that is influenced by chromatic aberrations caused by an optical system is selected as a reference color, and coordinates after conversion are calculated by applying conversion for correcting a distortion of the optical system with respect to the image to coordinates of pixels in association with the reference color. Correction values indicating amounts of color misregistration are calculated using the proportional relationship of difference values between the calculated coordinates and coordinates obtained by applying the conversion to coordinates of the image in association with remaining colors except for the reference color of the plurality of color components. Based on the calculated correction values, coordinates obtained by applying the conversion to coordinates of the image in association with the remaining colors are calculated.

Abstract: An image capturing apparatus chooses a main face from among faces detected in successively captured images based on a degree of priority calculated for each detected face. Moreover, the image capturing apparatus compares the degree of priority assigned to the face corresponding to a last chosen main face and the degrees of priority assigned to the faces corresponding to faces other than the main face, and then counts the number of times the degrees of priority assigned to the faces corresponding to faces other than the main face exceed the degree of priority assigned to the face corresponding to the main face. When one of the number of times counted for the faces other than the main face exceeds a preset threshold value, the image capturing apparatus performs a main face changeover to the one of the faces.
