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.
摘要翻译：保护磁记录介质的方法包括测量主电源继续保持在断开状态并且磁记录介质继续保持在预定位置的时间段。如果测量的时间段达到预定时间段（例如60分钟），则磁记录/重放头被移动到记录介质的记录/重放区域之外的原始位置或待机位置，从而防止磁头由于两者之间的连续按压接触，不能将它的印象留在记录介质的磁记录/播放区域上。

摘要： In a method of and apparatus for split photometry, a plurality of split photometric areas are established by setting a plurality of horizontal and vertical photometric intervals respectively within intervals in a horizontal scanning direction and a vertical scanning direction of the solid-state electronic image sensing device. An extracted luminance-signal component is integrated over a horizontal integration interval designated by an integration control signal. Integrated values obtained by the integration operation are summed, in every split photometric area, over the corresponding vertical photometric interval, and a photometric value is calculated for every split photometric area based upon the value obtained by summing the integrated values in another embodiment, data for controlling exposure or controlling the focusing of an image pick-up lens can be obtained for each of a plurality of blocks set in a photographic area. From data representing the image of a subject, a luminance signal is generated and converted into digital luminance data which is applied to a gate array. The luminance data is summed block by block in the gate array and the summed data is outputted in block units. Only the necessary data is selected from the summed luminance data of every block and a photometric value is calculated. A diaphragm and an electronic shutter is controlled based upon the photometric value calculated. A high-frequency component signal for focusing control can be calculated for each and every block in a similar manner.

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： 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 device for tracking a rotary recording medium includes a playback head for reading a signal from any of a plurality of tracks which are formed on the rotary recording medium, which is rotating at a predetermined constant speed, such that a beginning and an end of a recording in each of the tracks coincide with each other, a head support mechanism supporting the head such that the head is movable along the recording medium, an arrangement for detecting an envelope of a signal which is read out of the recording medium by the head, and a controller for controlling the head support mechanism to move the head to a position where a desired one of the tracks is located. An arrangement for detecting a position of the head relative to the recording medium and an arrangement for detecting a rotation phase of the recording medium are provided. The controller controls the head support mechanism to transport the head, while the position detecting arrangement during transport of the head detects positions of the head at which a peak of an envelope is detected in one track at each of a plurality of angles of rotation of the recording medium. The controller produces a means position of those positions of the head detected and, then, controls the head support mechanism to transport the head to the mean position.
