An image processing apparatus and method in which not only a partial image in a stereo image but also an image in a large range of near and far sides can be viewed are provided. First to twelfth viewpoint images are generated so that no disparity occurs in a portion specified as a principal object image. First to third viewpoint images viewed at a left end of viewing positions among the first to twelfth viewpoint images are shifted to set disparity of the object image specified as a sub target point at '0'. The tenth to twelfth viewpoint images viewed at a right end of the viewing positions are shifted to set disparity of the object image specified as a sub target point at '0'. The viewing positions are moved in a horizontal direction, to change an object distance of a stereo view image viewed on a lenticular sheet.

A dual lens camera for producing a three-dimensional image includes plural lens systems and a zoom mechanism. Initial correction data is constituted by a displacement vector of an amount and a direction of misalignment between plural images according to a superimposed state thereof for each of zoom positions of the lens systems. A vector detector, if a calibration mode is set, obtains a current displacement vector related to one first zoom position. A data processor outputs current correction data by adjusting the initial correction data according to the initial correction data and current displacement vector. If the current correction data is stored, a displacement vector is obtained from the current correction data according to a zoom position of the lens systems upon forming the plural images, to carry out image registration between the images according to the obtained displacement vector for producing the three-dimensional image.

Multi-lens camera and control method

A multi view imaging device according to an aspect of the present invention detects vibration applied to a plurality of imaging means and corrects, for each of a plurality of imaging means, an image blur of a subject image taken by the imaging means caused by the vibration. The image blur is corrected to make the amounts of remaining blur of the image blur after the correction substantially the same among the plurality of imaging means. As a result, even if there are variations in operation characteristics and installation errors of image blur correction means arranged on the imaging means, an appropriate image blur correction can be performed for each imaging means. Since the amounts of remaining blur of the subject image after the image blur correction in the imaging means are substantially the same, a comfortable, natural parallax image that is good for eyes can be obtained.

An image-capturing apparatus is capable of capturing a three-dimensional image and a high quality panoramic image as the need arises, and is portable if it is used as a single lens camera that captures a normal two-dimensional image. A second image-capturing unit having an image-capturing optical system is detachably connected to a first image-capturing unit, which is capable of functioning as an image-capturing apparatus by itself, through joints and a connector. The second image-capturing unit can extensively connect to other units, which have the similar connecting structure. Information is transmitted between the units through a slot for an external storage device. There is provided a means for adjusting the positions of images captured by the second and subsequent image-capturing units with respect to an image captured by the first image-capturing unit. In synchronism with release signals from the first image-capturing unit, the other units are driven to capture the images at the same time or continuously.

A lens frame is contained in a lower lens barrel and moves in a direction of an optical axis as guided by a guide shaft. An adjusting lever is provided with a lever body having a bearing for supporting the lower end of the guide shaft and an opening into which an adjusting pin is inserted, and a holding portion extended from near the opening of the lever body to outside the lower lens barrel. A length between an edge of the holding portion and a center of the opening is longer than the length between the center of the opening and a center of the bearing. The lever moves around the adjusting pin in a plane orthogonal to the optical axis to adjust the position of the guide shaft.

The present invention provides a digital camera in which the start-up time which is from when a power source is turned on until the digital camera is in a state in which photographing is possible is short. A DC motor and a stepping motor are driven simultaneously. A cord plate which is provided in advance at an outer circumferential surface of a rotating cylinder is detected. Then, the stepping motor is driven to move the focus lens by a movement amount corresponding to a detected range of the cord plate. When the setting of various types of components necessary for photographing other than the lens groups has finished, even if the zoom lens groups (forward lens group and backward lens group) are moving to their home positions, the digital camera is in a state in which photographing is possible.

An optical low-pass filter for a solid-state image sensor of an offset sampling structure is constituted of first and second optical members. The first optical member splits an incident light ray into a rectilinear ray and a refracted ray whose propagation direction is about 45&deg; to a horizontal direction of the solid-state image sensor. The second optical member splits an incident ray into a rectilinear ray and a refracted ray whose propagation direction is about 90&deg; to the horizontal direction. The optical low-pass filter having this configuration splits the incident light ray into four rays whose split points are at respective corners of a parallelogram. Assuming that Px represents a sampling interval in the horizontal direction, Py represents a sampling interval in the vertical direction, and D1 and D2 represent respective split widths of the incident light rays through the first and second optical members, the split widths D1 and D2 satisfy the following conditions: D1&ap;Px/{square root over (2)} and Py&lE;D2&lE;2&middot;Py.
