Abstract: A camera in which the ratio of an object to the photographing frame can be set comprises a varifocal lens in which the in-focus position is changed in accordance with the change in the focal lens and a focusing lens for correcting the focus by the varifocal lens. The size of the object is set to the desired size by using the varifocal lens, and thereafter the deviation of the in-focus point is controlled by the focusing lens. Since the zooming is carried out by using a varifocal lens, a camera can be provided in which the ratio of an object to the photographing frame can be set in a simple structure.

Abstract: A camera wherein the light emitted by a subject, which has passed through a photographic optical system, is formed as an image on an area sensor, and which includes an electronic viewfinder that indicates the image of the subject based on the output from the area sensor and an apparatus that detects image shaking caused by camera shake, based on the output from the area sensor.

Abstract: A camera comprises an angular velocity sensor for detecting camera-shake. The angular velocity sensor takes a certain time to be stabilized after its operation is started. When correction of camera-shake is required during the certain period, it is displayed that correction of camera-shake is not possible. As a result, a photographer using the camera with the camera-shake detection sensor refrains from photographing when correction of camera-shake is not possible.

Abstract: A camera having a blurring correction apparatus according to the present invention includes a photographic lens for forming an image of an object to be photographed, a detecting apparatus for detecting the degree of movement of the formed image of the object, a correcting apparatus operative at least during exposure time for correcting the position of the image of the object in response to a detection output of the detecting apparatus so as to compensate the movement of the image of the object, a setting apparatus for setting exposure time, a calculating apparatus for calculating the amount of movement of the image of the object produced during exposure time based on the detection output of the detecting apparatus and the set exposure time, and a prohibiting apparatus for prohibiting the operation of the correcting apparatus when the amount of movement of the image of the object produced during exposure time is smaller than a predetermined value.

Abstract: A new compact-size, light-weight and low-cost zoom lens system having a high optical quality with a very simple structure including, from the object side to the image side, a front lens group having a positive refractive power and a rear lens group having a negative refractive power. The zoom lens system is operated by changing the axial air distance between the front and rear lens groups during a zooming operation. The zoom lens system uses aspherical surfaces whose low-cost manufacturing has been enabled by the recent progresses in plastic molding technology and glass molding technology. Many embodiments of the lens compositions according to the present invention, and further more specific examples of the embodiments are described with figures and data that show compactness and high optical performance.

Abstract: A camera capable of blurring correction includes an acceleration sensor detecting camera-shake amount, and a blurring correcting device correcting blurring of image on the basis of the sensor output. When a lens of the camera is driven for automatic focusing, the blurring is not corrected using an output of the acceleration sensor. Accordingly, blurring is not wrongly corrected.
