A medium processing method is provided that includes the steps of inputting images of a first medium and a second medium, recognizing first area information of the first medium and second area information of the second medium, determining a correspondence between the first area information and the second area information based on the recognition result, adjusting one of the first area information or the second area information based on the determined correspondence between the first area information and the second area information, and compositing the adjusted one of the area information within a predetermined area defined by the other one of the area information.

Medium processing method, copying apparatus, and data filing apparatus

An image capturing apparatus in which an image of a subject formed by lenses and a low pass filter of a photographic optical system is provided to an imaging device unit that supplies a corresponding signal to an A/D converter that in turn provides an output to an image processing unit. A blur-detecting device with a blur detecting part and a blur detecting unit detect blur that is compensated by a blur compensating unit with a blur-compensation driving unit. A system controller computes a displacement amount for blur compensation by the blur-compensation driving unit driving the blur compensating unit based on an output of the blur detecting device. A memory group is included for calibrating a conversion coefficient used by the system controller in calculating the displacement amount.

Image capturing apparatus with blur compensation

A camera with a blurring correction unit including, a displacement sensor attached to the camera and capable of measuring a displacement of the camera, and driving mechanisms and capable of independently moving an optical component or a photographic member including a lens in at least two directions, respectively, the driving mechanisms actuated in accordance with a detection signal of the displacement sensor the camera capable of correcting a disturbance in a picked-up image due to blurring, wherein soft focus is attained by forcedly actuating the driving mechanisms and of the blurring correction unit.

Camera

The lens interlock mechanism includes the first driving unit, the second driving unit, and the third driving unit. The first driving unit moves the zoom lens along the optical axis direction of the zoom lens while giving a first driving force corresponding to the movement of the zoom lens to the third driving unit. The second driving unit gives a second driving force corresponding to a distance between the subject to the third drive unit. The third driving unit receives the first and second driving force given from the first and second drive units, and thereby, moves the focus lens in its the optical axis direction while keeping a predetermined relation to the zoom lens based on the distance to the subject.

Lens interlock mechanism and lens interlock method, camera and portable terminal having lens interlock mechanism

An apparatus for driving a photographic zoom lens in which at least a first and second lens group are disposed on the same optical axis and wherein the apparatus makes it possible to rapidly perform a zooming operation for changing a focal length of the photographic zoom lens. The apparatus comprises a fixed frame and a body tube frame supported within the fixed frame so as to be capable of moving along the optical axis. The apparatus further comprises a first group frame supporting a first lens group, a zooming cam, and a second group frame fixedly supporting a second lens group. Additionally, the apparatus includes a first group driving screw having a first multiple thread screw on a circumferential surface thereof, and adapted to be driven through a first group driving gear and a transmission gear; and a body tube frame driving screw having a second multiple thread screw, and adapted to be driven through a body tube frame driving gear and the transmission gear. The apparatus of the present invention makes it possible to rapidly perform a zooming operation and a housing operation when the power of a driving source and the radius of a driving screw are fixed.

Apparatus for driving varifocal lens

A device for driving a varifocal lens, includes a first group frame supporting the first group of lenses therein in a movable manner for focussing and supported with the lens barrel inside said fixed frame movably in parallel with said optical axis, a second group frame supporting the second group of lenses therein in a fixed manner and supported with the first group frame inside the first group frame movably in parallel with said optical axis, at least three driver screw members disposed within the fixed frame in parallel with optical axis, at least three driver gear members held in mesh with the driver screw members respectively, and a drive unit for driving the driver gear members to thereby move the lens barrel frame and the first group frame by a predetermined amount respectively.

Drive device for a varifocal lens system

A varifocal camera, comprising a photographic lens barrel having a photographic lens able to change the focal distance and adapted to move rearwardly when the photographic lens is transferred to the first focal distance side and move forwardly when the lens is transferred to the second focal distance side, a photographic lens barrier movable between the opening position at which the photographic lens is exposed and the closing position at which photographic lens is screened, and a finder barrier movable between the opening position at which the finder lens is exposed and the closing position at which the finder lens is screened.

Varifocal camera

A finder switching apparatus in a two-focus camera in which a finder is switched in conjunction with switching of a lens of the camera between shorter and longer focuses. The finder switching apparatus has a spring mechanism which can amplify a displacement of a parallax correcting lens which is adapted to move in interlocking engagement with the lens barrel so that the mechanism for moving the parallax correcting lens can be small. Accordingly, the two-focus camera having the finder switching apparatus according to the present invention can be made compact, since the space required for storing the finder switching apparatus in the camera is small.

Finder switching apparatus for camera

A two-focus camera in which a short focal-distance lens system is constituted by only a main lens when the main lens is set at a first position on an optical axis and a converter lens is set at a second position out of the optical axis, and a longer focal-distance lens system is constituted by the main lens and the converter lens when the main lens is set at a third position in front of the first position on the optical axis and the converter lens system is set at a fourth position behind the main lens on the optical axis.
