Abstract: A digital camera having an image shake correction apparatus and a method of preventing the image shake of an image taken by the digital camera. The digital camera includes optical elements arranged along a bent line for focusing an object image upon a light receiving plane in which the elements include at least one mirror which reflects a light from an object toward the light receiving plane, a driver for moving the mirror so as to turn its light axis having been bent by the mirror, a vibration sensor for sensing a vibration of a camera body, and a processor for making the driver move the mirror based on the sensed vibration. The mirror turns so as to cancel the vibration of the object image focussed on the light receiving plane.

Abstract: Imaging lens device has a zoom lens system and an image sensor. The zoom lens system has a first reflecting surface, a first movable lens unit, an aperture stop, a second reflecting surface, a second movable lens unit. A first reflecting surface bends a first optical axis which is an incident optical axis of the zoom lens system 90 degrees into a second optical axis. A second reflecting surface bends the second optical axis 90 degrees into a third optical axis. The first optical axis, the second optical axis and the third optical axis are mutually perpendicular. The first movable lens unit and the aperture stop are disposed on the second optical axis. The second movable lens unit is disposed on the third optical axis. During zooming, the first and second reflecting surfaces and the aperture stop are stationary; the first and second movable lens units are moved, respectively.

Abstract: A digital camera which allows to make thickness, height and width of its camera body small. The camera has a first optical member for generally perpendicularly bending a first optical axis of light coming from an object through a lens opening part, a second optical member for bending a second optical axis of light coming from the first optical member, and an image taking element having a light receiving surface for receiving a third optical axis of light coming from the second optical member in which the light receiving surface crosses the third optical axis of light. The third optical axis of light is included in a plane which is different from a plane including both of the first optical axis of light and the second optical axis thereof.

Abstract: A camera, as soon as the user finishes using it, quickly assumes a not-in-use appearance that the camera is designed to assume when it is out of operation. The camera incorporates, inside its body, a taking optical system including a turning optical system for turning the optical path of the light from a shooting target substantially at a right angle and a zoom optical system for varying shooting magnification. The body has an opening through which the front face of the taking optical system is exposed, and has a barrier for closing the opening. The camera, when a command to stop operation is given, performs the process of closing the barrier with highest priority, and then performs the process of extinguishing display with second highest priority. The camera, now having assumed an appearance that it is supposed to assume when out of operation, then performs other, internal, processes for stopping operation.

Abstract: A photographing device having a flexion optical system which prevents a user's finger(s) from interfering with a lens opening portion carelessly or unpreparedly, and which allows constituent parts of the photographing device to be arranged effectually inside a body thereof to make it low-profile and compact. The flexion optical system extends fully in a direction of right and left of the body thereof, or fully in a direction of up and down of the body, as the photographing device in a standard posture, or position, is viewed from a side of an object, the image of which is captured by the photographing device.

Abstract: First, a lens is supplied with a power supply LVDD. Then the state of a chip select signal CSL is input, and the processing waits until chip select signal CSL changes from HIGH.fwdarw.LOW.fwdarw.HIGH, that is, until communication preparation on the lens side is completed. When a microcomputer on the lens side is reset and started, the lens side outputs a communication enable signal and thus the time from mounting of the lens to starting of a communication can be reduced. Thus, a lens-exchangeable camera can be provided capable of starting a BL communication in the shortest time depending on the lens.

Abstract: When a communication header transmit from the lens side to the body side is input, a reset and start detection signal is checked and if the lens is found to have been reset and started, a body/lens identify signal is communicated to exchange identification signals of each other and the like and resetting of the mechanism is instructed. Thus, malfunction of the lens can be prevented even when the microcomputer for the lens side is reset with the lens mounted on the body.

Abstract: A mode selecting system of a camera which comprises a first mode group which includes a plurality of photo-taking modes, wherein photographing parameters are automatically set by the camera when each one among the modes of the first mode group is selected, and a second mode group which includes a plurality of photo-taking modes, wherein at least one of photographing parameters is manually settable when one among the modes of the second mode group is selected.

Abstract: A flashlight emitting device for a camera wherein the flash coverage of a flash device is varied, only when a mode in which flashlight is to be emitted is selected, in response to a zooming operation to assure appropriate exposure and eliminate wasteful consumption of power.

Abstract: An autofocus camera comprises a focus detector for detecting a deviation of a photographic lens from an in-focus position with respect to a photographic object, a mirror driver for moving a mirror for reflecting a light beam from the photographic object to a viewfinder optical system, into and out of an image-forming optical path, a lens driver for moving the photographic lens to the in-focus position in accordance with the deviation detected by the focus detector, and an aperture controller for stopping down the light beam from the photographic object. The lens driver has a function for moving the photographic lens, and the aperture controller a function for making aperture adjustment, both during retraction of the mirror. During retraction of the mirror, the aperture adjustment is effected before the lens movement or vice versa.
