A camera with vibration reducing function includes a vibration detecting device for detecting vibrations of a camera, a photography directing unit for directing the camera to perform photometric/distance measuring operations by a turn-ON process and stopping the photometric/distance measuring operations by a turn-OFF process, a mode setting unit for directing the camera to set a specified mode, and a control device for controlling the vibration detecting device in accordance with the directions given from the photography directing unit and the mode setting unit. The control device makes the vibration detecting device continue the vibration detecting operation for such a duration that the mode setting unit sets the specified mode and that the photography directing unit is operated in the ON-state.

Camera with vibration reducing function

A camera with vibration correcting function is provided with a plurality of vibration detecting devices for detecting the vibration of the camera, a plurality of vibration correcting devices for effecting vibration correction control in conformity with the respective outputs of the vibration detecting devices, and an abnormality detecting device for detecting the abnormality of the output of the vibration detecting devices, and only the vibration correcting device corresponding to the vibration detecting device having the output for which abnormality has been detected by the abnormality detecting device is inhibited from effecting the vibration correction control.

Camera with vibration correcting function

An opening and closing apparatus for opening and closing a light blocking door provided at a film feed slot of a film cartridge comprises a drive device that drives the light blocking door to open and close, a single switch that outputs a signal with a specific pattern with a light blocking door opening and closing operation of the drive device and a control device that controls the drive device based upon the output signal from the switch. The switch, for instance, includes a switch pattern that is integrated with a rotating member constituting the drive device and a brush that slides on the switch pattern as the rotating member rotates.

Camera equipped with light blocking door opening and closing mechanism

This camera capable of image blur reduction includes a photographic device which performs photography, a camera vibration detection device which detects the value of a physical quantity related to the amount of camera vibration, an image blur reduction device which performs image blur reduction operation based upon the output of the camera vibration detection device in order to reduce blurring of the photographic image caused as a result of camera vibration, and a control device which causes the operation of the image blur reduction device after a predetermined time period has elapsed from the time point of starting of operation of the camera vibration detection device, and which causes the operation of the photographic device during the operation of the image blur reduction device.

A camera adapted to receive a film cartridge having a recording member on which is recorded information relating to a total number of available frames in a film is provided. This camera includes an information detector that detects the information relating to the total number of available frames that is recorded on the recording member, a display unit that displays the information relating to the total number of available frames, an abnormality judging unit that determines whether any abnormality is present in the information relating to the total number of available frames that is detected by the information detector, and a display controller that controls a display of the display unit according to a result of judgement made by the abnormality judging unit.

Camera capable of displaying information relating to the number of

A vibration compensation camera to correct image vibration occurring due to camera vibration by driving a vibration compensation lens according to vibration detected by a vibration detection circuit. The vibration compensation camera also includes a delay mode setting device to set a time delay to perform a shutter opening operation after a predetermined time has elapsed after a release operation. When the delay mode setting device is set to the delay mode, the vibration compensation system is not operated, thereby reducing electric power consumption. The vibration compensation camera may also have a bulb mode function to perform photography while in a bulb mode. A bulb mode setting device sets a bulb mode to maintain a camera shutter in an open state. When the bulb mode setting device is set to the bulb mode, the vibration compensation system is not operated. The vibration compensation camera may also have a timed delay function to start the vibration detection circuit after a first delay time has elapsed from a release operation and to perform a shutter opening operation after a second delay time has elapsed from the release operation.

Vibration compensation camera having reduced power consumption in a

There is disclosed an electric camera which comprises a switch for switching a state of the camera between a state out of use and a state in use, a driving member for shifting the position of a member to be driven to change its state between a state out of use and a state in use in accordance with the state switched by the switch, detection unit for detecting whether the member to be driven is shifted during an operation of the driving member, counter unit for starting counting when the driving member is started to operate upon switching by the switch, change-over unit for changing over a driving speed of the driving member from a first speed to a second speed which is lower than the first speed, and control unit for stopping the drive of the driving member when the counter unit counts a predetermined time, so that the camera can be used continuously when the photographing lens or the barrier is stopped due to external forces, etc., and then the cause thereof is removed, and battery consumption can be suppressed to the minimum.

Electric camera

A camera which performs high precision motion compensation while multiple, serial photographs are taken, by stabilizing the output signal of a motion sensor until the final photograph is taken. An exposure control mechanism causes the camera to take a first photograph after a first time period elapses from the initiation of exposure, and to take a second photograph after a second time period elapses from the first photograph being taken. A motion detector continuously detects motion affecting the camera prior to the first photograph being taken until after the second photograph is taken, and produces a corresponding output signal. A reference level mechanism determines a reference level from the output signal of the motion detector. The reference level is a level of the output signal which indicates that approximately no motion is affecting the camera. The reference level mechanism updates the reference level prior to the first photograph being taken until after the second photograph is taken, to produce a current reference level. In addition, a motion compensation mechanism receives the current reference level from the reference level mechanism and the output signal of the motion detector, and accordingly compensates for motion affecting the camera.

Camera which performs motion compensation for sequential photographs by

A display device has a display having a scale plate and an indicator movable on the scale plate, an instruction unit for releasing an instruction signal for moving the indicator, and a drive unit for moving the indicator based on the instruction signal. The device also has a detector for detecting whether the indicator is in movement or not. When the detector detects that the indicator is in movement, the movement of the indicator by another new instruction signal, eventually released from the instruction unit, is inhibited. Such movement of the indicator by another new instruction signal is permitted only when the detector detects that the indicator is not in movement.
