摘要： A disc drive device optimally controls a speed for reading RTR-format data, such as video and audio, recorded on a DVD-format disc, thereby enabling real-time playback without interruption. In the disc drive device, information added to each sector is used for determining whether data is RTR-format data. When an error occurs at high-speed reading of RTR-format data and therefore the reading speed is changed to a low speed, the reading speed is so controlled as to be kept at the low speed for reading the following RTR-format data. Thus, for RTR-format data, overhead due to repetitive acceleration and deceleration processes can be avoided, and reading can be carried out without interfering with real-time playback. For normal data, reading can be carried out in a manner similar to that in the background art.
摘要翻译：磁盘驱动器件最佳地控制用于读取记录在DVD格式盘上的RTR格式数据（例如视频和音频）的速度，从而实现无中断的实时播放。在盘驱动装置中，添加到每个扇区的信息用于确定数据是否为RTR格式数据。当RTR格式数据的高速读取发生错误时，读取速度变慢，读取速度被控制为低速读取下列RTR格式数据。因此，对于RTR格式的数据，可以避免由于重复的加速和减速处理引起的开销，并且可以在不干扰实时重放的情况下执行读取。对于正常数据，可以以与背景技术类似的方式进行读取。

摘要： A flash control system remotely controls an external flash by a camera. In the camera, a stop value is calculated as a photographic exposure factor for the external flash, and a flash-light emission timing of the external flash is calculated. A built-in flash of the camera is controlled to emit two light signals at a time interval representing the stop value. The external flash detects the two light signals. A timing of a flash-light emission of the external flash is controlled in accordance with one of the two light signals. An amount of the flash-light emission of the external flash is controlled in accordance with the time interval.

摘要： A lens focusing system for a camera. The camera includes a focusing lens that is movable between a first terminus point and a second terminus point. An amount required to move the focusing lens to obtain an in-focus condition is determined, which is used to drive the focusing lens to position the focusing lens at the in-focus condition. A plurality of drive signals are generated in response to the driving of the focusing lens, which are monitored. A monitored position value is established that is based upon the plurality of drive signals monitored by the monitoring means, and the monitored position value is compared with a predetermined position value corresponding to one of the first terminus point and the second terminus point after the lens has been moved by the amount determined to be required to move the focusing lens to obtain the in-focus condition. The focusing lens is then driven in a direction until the focusing lens is prevented from moving when the monitored position value corresponds to a position which is out of a range between the first terminus point and the second terminus point. When the focusing lens has been moved to one of the first terminus point and the second terminus point, the monitored position value is replaced with the predetermined position value.

摘要： An image magnification control device for a camera. Control focal length required to maintain an image magnification constant is computed based upon defocus information detected by using a light having passed through a photographic lens. In case focal length of the photographic lens comes out of a range wherein the set image magnification can be obtained, various operations such as shutter-release lock operation are executed depending upon designs.
