Abstract: A CCD camera takes rearview images of a vehicle so as to input them into a superposing image displaying device, and a vehicle index database stores a vehicle index indicating a vehicles's protruding region such as a spare tire for displaying the protruding region over a rear end of a rear reference position such as a bumper of the vehicle in the rearview image. A superposed image displaying device superposes the vehicle index stored in the vehicle index database and the rearview image taken by the CCD camera so as to provide a monitoring device. Thus, a rearview monitoring apparatus for a vehicle for displaying the rearview image of the vehicle and information of the protruding region for occupants in the vehicle can be provided.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

In addition, a print area display section for displaying the print area set by the print area setting section in the finder of a camera, a focal length information storage section for storing the focal length information of a photographic lens, and a trimming mode selecting section for selecting a trimming mode are connected to the control section. When the trimming mode is selected by the trimming mode selecting section, the hand shake prevention mode is automatically selected, thereby easily preventing a deterioration in image quality due to a hand shake.

Abstract: A camera having a sound recording function is disclosed, in which an object image is photographed/recorded, as an optical image transmitted through a photographic optical system or photoelectrically converted image data, on a film having a magnetic recording portion, a magnetic disk/tape, or the like, while sound data is sampled for a predetermined period of time before/after the photographic operation. The sampled sound data is temporarily stored in a sound data storage section constituted by a semiconductor memory and the like. In a film wind-up operation, the sound data is written in the magnetic recording portion of the film. With this operation, the predetermined number of frames can be photographed regardless of whether sound data is present or absent.
