A cleaning medium flies with an air current in a cleaning tank to collide with an object to be cleaned so as to remove an extraneous substance attached to the object. The cleaning medium includes an outer surface that comes into contact with the object and an inner surface that remains out of contact with the object. The cleaning medium is flexible and formed in a shape that allows the air current to flow from the outside onto the inner surface of the cleaning medium.

A circulation-air generating unit directly generates circulation air that flows along a surface of a cleaning tank. The circulation air is applied to cleaning medium accumulated on the cleaning tank from a direction orthogonal to a direction of face of the cleaning medium to deliver and flow up the cleaning medium. The cleaning medium is flown up inside the cleaning tank by the force of the circulation air. The cleaning medium flowing inside the cleaning tank collides with a cleaning target object by high-velocity air supplied from a cleaning-medium accelerating unit to remove dust on the cleaning target object.

The present invention aims at providing a blur correction camera in which an image movement (blur) amount on an image forming plane is displayed more exactly based on the actual states of a camera shake and a blur correcting member. The blur correction camera includes a camera shake sensing section for sensing a camera shake, a blur correcting member for correcting an amount of image movement due to the camera shake, a first image movement amount arithmetic section for calculating an image movement amount on a film plane in response to an output of the camera shake sensing section, a second image movement amount arithmetic section for calculating an image movement amount on the film plane in response to an output of the camera shake sensing section when the image movement amount is corrected by the blur correcting member, and a third image movement amount arithmetic section for calculating a difference between an arithmetic result of the first image movement amount arithmetic section and that of the second image movement amount arithmetic section.

Blur correction camera

The present invention provides a camera with a blur warning function which does not widely vary in feeling of use between film-loading and film-unloading. In this camera, a film loading sensing section senses whether a film is loaded or not, a focal length sensing section senses a focal length of a lens, and a camera shake sensing section senses a camera shake. In response to outputs of the film loading section, the focal length sensing section and the camera shake sensing section, a blur amount of an image formed on a film surface is computed by an image blur computing section. A blur warning section gives a warning of an image blur amount in response to an output of the image blur computing section. The information of the blur warning section is controlled by the image blur computing section in accordance with at least information of the film loading sensing section.

A camera with a condition indication facility allows a photographer to be informed of a camera shake condition through the use of a relatively simple construction. A plurality of shake level indicators are provided in the rear cover of the camera. The indicators are placed in the rear cover so that, when the rear cover is closed, they are positioned near the viewfinder window so as to allow the photographer to confirm the operating conditions of the camera while looking through the viewfinder window.

Camera with condition indication facility

A camera with shake compensation which detects camera shake and cancels image blur on a film exposing aperture due to the shake. The camera is capable of conserving battery power by automatically entering a power saving stand-by mode in which some of the functional blocks of the camera are powered down. The camera includes a selectable shake compensation mode, camera shake detecting circuits, and a control circuit that does not allow the shake detecting circuits from entering stand-by mode whenever the shake compensation mode is active. As a result, the camera is ready to perform shake compensation immediately upon exiting stand-by mode.

An anti-shake camera measures a shaking movement of the camera around at least a first dimension and around a second dimension (e.g., X and Y dimensions). Based on these measured camera shake values, the anti-shake camera generates a forecasted camera shake value for each measured dimension of motion. When both of these forecasted camera shake values achieves a predetermined level, such as zero, within a predetermined time, the anti-shake camera begins an exposure operation.

Anti-shake camera

A shake correcting apparatus for a camera includes a shake detector for detecting a shake state of a camera, a shake correcting section for executing shake correction based on a detection result from the shake detector, and a shake correction driving section for driving the shake correcting section. A relative position detector detects a relative position state of the shake correcting section, and an end position detector detects an end position state of the shake correction section. A discriminator discriminates at least one of an operational status of a camera and history data of shake correction driving. An initial position of shake correction for initialization of the shake correcting section is set based on the detection result from the relative position detector. A driving mode of driving of the shake correcting section to the set initial position is changed based on a discrimination result from the discriminator. Initial-position setting sections may be provided for setting an initial position of the shake correcting section.

In an image blur prevention device for a camera, the limit delay time for image blur reduction is set to be changeable so as to reduce the influences of camera shakes on photographing operations, so as to realize high operability. A shake determining section determines the image blur state on the current image plane on the basis of the camera shake state detected by a shake detecting section. As a result, information corresponding to the level of the current image blur state is sent to an exposure control section. On the basis of image blur state information from the shake determining section when an exposure start instruction signal is received, limit delay time information set in a limit delay time setting section, and the count result obtained by a timer section, the exposure control section determines whether to start an exposure operation in accordance with the state of a release operating section. If it is determined that exposure should be started, a shutter unit is driven by a shutter drive section to perform an exposure operation. If it is determined that exposure should not be started, the shutter drive section is stopped, and no exposure operation is performed.
