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.
摘要翻译：一种用于相机中的白平衡调节装置，其对场进行拍摄并形成表示场的视频信号。在白平衡调整装置中，当进行顺序拍摄时，禁止更新用于调整白平衡的色温数据。因此，通过顺序拍摄操作拍摄的静止图像的各个帧中的主要对象的色调保持不变，从而保持主要对象的均匀性。此外，在白平衡调整装置中，控制装置用于为静止模式下的快速响应特性提供短的响应时间，并且与静止模式相比在电影模式中提供较长的响应时间。因此，可以根据相机的拍摄模式来调节白平衡。

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.

摘要： A method of protecting a magnetic recording medium includes measuring a time period over which a main power supply continues to remain in an off state and the magnetic recording medium continues to remain loaded at a predetermined position. If the measured time period attains a predetermined time period (e.g. 60 minutes), a magnetic recording/playback head is shifted to an origin position or a stand-by position outside a recording/playback area of the recording medium, thereby preventing the magnetic head from leaving its impression on the magnetic recording/playback area of the recording medium due to continuous pressing contact between the two.

摘要： In an electronic still-video camera capable of frame recording using a shutter, read-out is controlled in such a manner that dark currents generated in an imaging device will be equal in both first and second fields. Thereby, the recording of a still-video signal that will provide an excellent and easy-to-view reproduced image that is free of flicker is made possible.

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.
摘要翻译：当将包含磁盘的盘片装载在静止摄像机中时，将搜索磁盘上的所有轨道，以确定每个轨道是否已经被记录在一起，或者是空白的，并且将搜索结果存储在存储器中。如果已经设置了连续的拍摄模式，则磁头从原始位置向前馈送并且位于跟踪的最后轨道旁边的轨道上。由于磁头已经被定位到磁盘的最终轨道的轨道的所有剩余磁道将是空白的，所以在连续拍摄操作期间磁头的馈送被简化。换句话说，在连续拍摄模式中，只要在每次拍摄静止图像时一次将头部馈送到一个轨道就足够了。

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.
摘要翻译：静止摄像机包括色温传感器，用于检测在从摄像系统输出的视频信号的色彩平衡调整中使用的环境光的色温。相机还包括选通发光电路，其产生指示何时能够执行频闪发射的信号。控制电路基于在没有选通准备就绪信号的情况下由颜色传感器检测到的色温来控制视频信号的色彩平衡的调整。在启动快门释放开关时，控制单元确定是否存在选通准备就绪信号。如果存在选通信号准备好信号，则控制单元将色温固定为预定的恒定值，以进行色彩平衡调整。因此，只有当实际发生闪光发光时才基于与闪光灯拍摄相对应的固定恒定色温来进行色彩平衡调整，并且当选通发光电路基于固定恒定色温时，防止色彩平衡被调整处于就绪状态，但不会执行闪光灯摄影。
