Abstract: An image sensing apparatus is provided with an image sensor for photoelectrically converting received light into an electrical signal, a photographing optical system having an image circle larger than an area of the imaging plane of the image sensor for forming an optical image of a subject onto an imaging plane of the image sensor, and a driving section for driving the image sensor over a plane perpendicular to an optical axis of the photographing optical system, and a shift photographing mode for performing a photographing in a state that the center of the imaging plane of the image sensor is shifted from the optical axis of the photographing optical system.

Abstract: An electronic device has a display capable of displaying a pointing representation, a detector for detecting a movement of the electronic device, and a display controller for controlling the display so as to move the pointing representation displayed on the display in response to the movement of the electronic device detected by the detector. The pointing representation can be moved by a simplified operation or by moving the electronic device, which consequently reduces the number of operation parts.

Abstract: When an electronic book 1 momentarily moves by ?y in the direction of the arrow A because of a vibration, an image display 7 (an LCD module 15) is changed downward by ?y so that when the user is viewing an image, the user's line of sight is substantially fixed like when there is hardly any vibration on the electronic book 1. By performing such an operation in each of the X axis and Y axis directions, the relative position of the display image in the direction of the X axis with respect to the user's line of sight because of a vibration in the X axis direction (the direction of an arrow D) of the image display 7 (the LCD module 15) is made fixed, and the relative position of the display image in the direction of the Y axis with respect to the user's line of sight because of a vibration in the direction of the Y axis (the direction of an arrow C) of the image display 7 (the LCD module 15) is made fixed.

Abstract: A base plate, a first slider and a second slider are fit in one another to produce one assemblage. The first slider is caused to move relative to the base plate along an X axis by a first actuator. The second slider moves in unison with the first slider, and also is caused to solely move along a Y axis by a second actuator. A magnetic sensor unit is provided in the base plate, and a magnet support is provided in the second slider so as to face the magnetic sensor unit. A magnet is disposed on a lower face of the magnet support. The magnetic sensor unit and the magnet form a position detection mechanism, and the second slider in which the magnet is disposed requires no electric wiring.

Abstract: This camera includes two kinds of photographing modes, a normal photographing mode and a trimming photographing mode of telephotographing in pseudo. The focal length variator for changing the focal length of a zoom lens is formed by a first cam corresponding to the normal photographing, a second cam corresponding to trimming photographing, and a transition area cam connecting the first cam and the second cam. Thus, at the time of transition from the normal photographing mode to the trimming photographing mode, or the transition from the trimming photographing mode to the normal photographing mode, the focal length of the zoom lens is changed to the focal length corresponding to the photographing mode by zooming operation to facilitate change of the photographing mode and always set a view finder to a suitable angle of view corresponding to the focal length set in the zoom lens.

Abstract: A camera capable of switching two kinds of photographing modes, the normal photographing mode and the trimming-photographing mode capable of telephotographing in pseudo, and switching the photographing mode in an arbitrary position. A viewfinder cam for changing the focal length of a viewfinder optical system to confirm the range of an image plane to be printed through the viewfinder includes two cam faces corresponding to the photographing modes. When the cam face to be used is selected according to the photographing mode, a pin for changing the focal length of the viewfinder optical system interlocking with the zooming operation of the photographing lens is moved along the selected cam face, whereby the focal length of the viewfinder optical system is changed so that the angle of view of the viewfinder coincides with the angle of view of a photograph to be printed.

Abstract: A single-lens reflex camera comprises a taking lens having a zooming optical system, a finder whose angle of view is determined according to a focal length of the taking lens, and an operation member which is manually operated. In the single-lens reflex camera, the focal length of the taking lens is changed by driving the zooming optical system, and the zooming operation is controlled in response to an operation of the operation member so that the focal length of the taking lens is changed in the wide-angle direction by a predetermined amount. An angle of view corresponding to that which is seen before the focal length is changed is displayed within the finder.

Abstract: A camera is equipped with a finder having a field-of-view frame switching mechanism that is provided with, in addition to a stationary frame plate disposed in an optical path, two rotatable frame plates each of which moves in the optical pass to overlap with the stationary frame plate, to define three fields of different sizes. The stationary frame plate has a window of a standard size, one of the rotatable frame plates has a window of a classic size and the other has a window of panoramic size. Each of the fields of view is defined by a single frame plate. When the rotatable frame members are at their retracted positions, they substantially overlap with each other and are pushed by a spring in a direction to move in the optical path. Their movement is controlled by a cam member, which is moved in accordance with a user's operation to switch the size of a picture taken by the camera.

Abstract: A photographic camera of the type including a piezo-electric actuating element driven by energy accumulated in a capacitor for actuating a shutter wherein the piezo-electric element operates in stability to assure accurate appropriate opening and closing operation of the shutter of the camera and the capacitor is charged up rapidly to allow subsequent photographing operation to be done in a minute. In the camera, a charged voltage of the capacitor is checked several times to determine if it is sufficient to assure proper operation of the piezoelectric element, and if a then required level is not reached, then the capacitor is charged to the required voltage. While the capacitor is being charged, charging of a capacitor for a flash is inhibited.
