摘要:
A mode changing device for a camera employing a minimum number of actuating members to permit a user to change an operating mode and/or setting of the camera. A mode actuating member and a selector switch, used in conjunction with an LCD panel that indicates the mode and setting that has been selected by the user, permits the user to easily select and/or adjust the features of the camera, such as a photographing mode, a playback mode, an exposure mode, a white balance mode, a copy/monitor mode and a time/date mode. When the mode changing device is applied to a still video camera having a playback function, a change-over switch automatically changes the operating mode of the camera from a record mode to a playback mode when a monitoring adapter is connected to the camera, further reducing the number of actuating members that are needed to control the camera. In addition, the camera is designed to minimize the waste of electrical power by inhibiting the operation playback mode until the camera is instructed to begin operating.

An apparatus for detecting an open F number in a zoom lens camera including a cam ring which rotates to vary the focal length of a zoom lens, a reflection plate which is secured to the outer periphery of the cam ring and which has light reflecting portions and non-reflecting portions alternately arranged, as viewed along the circumferential direction of the cam ring, a photoreflector which emits light onto the reflection plate and which detects light reflected by the reflection plate, and an arithmetic device which calculates an open F number of the zoom lens using the output of the photoreflector.

摘要:
An electronic camera capable of both still picture photographing and motion picture photographing in which one operation can be switched over to the other with ease and in which a bright image of the object is provided in the viewfinder with little attenuation in the video signal level. Upon selection of the motion picture photographing mode, the image reflecting mirror is automatically retracted from the photographing optical path and the focal plane shutter is maintained open. The image reflecting mirror drive mechanism and the focal plane shutter drive mechanism are used for both still picture photographing and motion picture photographing operations. Also, the shutter release switch is used for both operations. In the motion picture photographing mode, the degree of opening of the aperture opening and closing mechanism is changed in accordance with the luminance of the image being photographed, while for still picture photographing, the exposure is controlled with the focal plane shutter.

A zoom lens camera having a zoom photographing lens and a zoom finder device are driven in association with each other so that the image plane and the finder field of view correspond to each other. A pair of pinions for the zoom photographing lens and the zoom finder device are provided in a gear train and are driven by a reversible motor so that the zoom photographing lens and the zoom finder device are driven by the respective pinions.
摘要:
An electro-developing type camera using an electro-developing recording medium on which an image is developed while an electric voltage is applied thereto. The image is read out from the electro-developing medium by a scanning mechanism. A color separation filter is disposed in front of the recording medium, so that R, G and B images are recorded on first, second and third recording areas, respectively. The color separation filter and the recording medium are disks rotatably provided. A photographing optical system is disposed at a first position at which the optical axis thereof is positioned above the rotational axes. The scanning mechanism is disposed at a second position at which the scanning mechanism is positioned under the rotational axes of the electro-developing recording medium and the color separation filter. Each of the recording areas is positioned above the rotational axes when a photographing operation of the recording area is carried out, and is positioned under the rotational axes when a reading operation of the image from the recording medium is carried out.
摘要:
An electronic still camera having a photographing system, a photographing element located at a surface of the photographing optical system on which an image is formed and a finder optical unit disposed separately from the photographing optical system. An optical path of the finder optical unit includes a forward optical path disposed parallel to and close to the photographing optical system, a rearward optical path disposed at a position away form an optical axis of the photographing optical system farther than the forward optical path and a deflected optical path for connecting the forward optical path to the rearward optical path and disposed at a position forward of the photographing element.
