    摘要: An image recording/reproducing apparatus is disclosed which records video signals obtained by photographing an object onto a magnetic recording medium, such as a magnetic disc or the like, or reproduces the video signals recorded on the magnetic recording media. In the image recording/reproducing apparatus, when the object is photographed in a sequential photograph mode, the video signals of the object, as well as, data signals representing the photograph data, including the number of frames to be photographed in one sequential photograph unit and its sequential speed, are recorded onto the magnetic recording medium. During reproduction, the frames recorded in the sequential photograph mode are reproduced at a sequential photograph speed corresponding to the sequential photograph speed of the recording as set forth by the data signals.

    摘要: An electronic still camera includes a solid-state imaging device for generating electric charges corresponding to an incident light thereto and for producing in the form of a unit of video signals the electric charges in response to a driving signal. An exposing unit has an optical shutter which opens and closes in response to an instruction signal to expose the imaging device to the incident light. A recording unit for rotating a rotary recording medium records the unit of video signals on the rotary recording medium. A phase detector detects a predetermined rotation phase of the recording medium to produce a phase detect signal, and a control unit is responsive to a shutter release button and the phase detecting unit for controlling the imaging device, exposing unit, and recording unit. The unit of video signals are recorded on the recording medium in rotation beginning from the predetermined rotation phase of the recording medium with reference to the phase detect signal. The control unit supplies the exposing unit in response to the shutter release button with a first instruction signal for opening the shutter at a point of time advanced by an exposure time with respect to the phase detect signal, supplies a driving signal to the imaging device immediately before the shutter is opened so as to cause the imaging device to discharge electric charges therefrom, and supplies a second instruction signal to the exposing unit to close the shutter. When the optical shutter is closed, a driving signal is fed to the imaging device at an ordinary video signal rate to cause electric charges of the imaging device to be developed in the form of a unit of video signals into the recording unit, which in turn records the unit of video signals on the recording medium.

    摘要: A still video camera includes a color temperature sensor for detecting the color temperature of ambient light which is used in the color balance adjustment of video signals outputted from an image pickup system. The camera further includes a strobe emission circuit which produces a signal indicating when strobe emission is capable of being performed. A control circuit controls the adjustment of the color balance of the video signals on the basis of the color temperature detected by the color sensor in the absence of a strobe ready signal. Upon the activation of a shutter release switch, the control unit determines whether or not a strobe ready signal is present. If a strobe ready signal is present, the control unit fixes the color temperature to a predetermined constant value for color balance adjustment. Color balance adjustment is therefore made on the basis of a fixed constant color temperature corresponding to strobe light photography only when strobe light emission is to actually occur and prevents color balance from being adjusted on the basis of the fixed constant color temperature when the strobe emission circuit is in a ready state, but strobe light photography is not to be performed.

    摘要: When a disc pack containing a magnetic disc is loaded in a still video camera, all tracks on the magnetic disc are searched to determine whether each track has been recorded on or is blank, and the results of the search are stored in memory. If a continuous picture-taking mode has been set, the magnetic head is fed forwardly from a home position and is positioned on a track next to the last track recorded on. Since all of the remaining tracks from the track at which the head has been positioned to the final track of the disc will be blank, feeding of the magnetic head during the continuous picture-taking operation is simplified. In other words, in the continuous picture-taking mode, it will suffice merely to feed the head one track at a time each time a still picture is taken.

    摘要: An apparatus for positioning a recording or playback head over a rotating recording medium, such as a magnetic disk. When access to a desired track is attempted, the head is quickly moved and placed within a range close to the track under open loop control. When the head enters the range close to the desired track, the head control is switched to servo feed under closed loop control. During the servo feed, the head is moved according to a head position signal representing the actual position of the head, the head position signal being given by a head position detector having a portion moving together with the head. The head is thus directed to a predetermined position according to an error signal corresponding to the deviation of the head position. When the head has passed through the desired position, driving force in the reverse direction is generated and the head is forced back toward the desired position. The head thus oscillates around the desired position but converges to it.

    摘要: A white balance adjusting device for use in a camera which photographs a field and forms a video signal representing the field. In the white balance adjusting device, while a sequential photographing is under way, updating of the color temperature data to be used for adjusting a white balance is prohibited. Therefore, the hues of main objects in the respective frames of still images photographed by the sequential photographic operation remain unchanged, thereby maintaining the homogeneity of the main objects. Also, in the white balance adjusting device, control a device is used to provide a short response time for a quick response property in a still mode and to provide a longer response time in a movie mode when compared with the still mode. As a result, the white balance can be adjusted according to the photographic modes of the camera.

    摘要: An apparatus for automatically providing white balance in an electronic still camera. When the camera is not in use a sliding cover is placed over the lens with a white translucent sheet facing the lens. At the beginning of use, the sliding of the lens cover to uncover the lens triggers a white balancing circuit to perform the required white balancing for the ambient light admitted through the white translucent sheet.
