摘要： It is an object of the present invention to perform a coordinate position detection not involving detection miss, even if a drawing process frequently involves detection interruptions on a display surface. A method of the invention comprises: performing a scanning in a first scanning area corresponding to the width of the display surface at the time of an initial detection of a shading object; performing, when continuing the detection of the shading object, a scanning in a second scanning area whose scanning region is an area near the latest detection position; performing, after an interruption in the detection of the shading object, a scanning in a third scanning area which is broader than the second scanning area but narrower than the first scanning area, within a predetermined time period and with the detection position of a continued detection serving as reference.

摘要： A coordinate position detecting apparatus includes: a scanning unit that scans a predetermined scanning area in predetermined scanning precision along a horizontal direction and a vertical direction with respect to a display screen by employing detection beams respectively. A position of a light shielding article on the display screen is detected in correspondence with scanning positions of the detection beams which are light-shielded. The scanning unit includes: a drive control unit that switches a plurality of scanning modes having different scanning accuracies from each other; and a moving speed detecting unit that detects a moving speed of the light shielding article. The scanning unit selects a predetermined scanning mode from the plurality of scanning modes in response to the scanning speed detected by the moving speed detecting unit to perform a scanning operation.

摘要： A servo control loop for a disc player initially sets an offset value, which is used throughout search and playback to control the gain of an equalizer in the servo loop. The offset value is determined by first moving a pickup head to radially central position of the disc and reading the time code address data recorded at that position. The read address is compared with a calculated, expected address to determine if the two are within a given distance. If they are, the offset is set as a predetermined value, e.g., zero. If they are not within a given distance, the offset is determined one of two ways. Either the difference is used as the offset, or the pickup head is moved to the innermost circumference of the data portion of the disc and the address data read therefrom is used as the offset. During search and playback the offset is subtracted from the continuously read address data, and the difference controls the gain of the equalizer.

摘要翻译： 用于光盘播放器的伺服控制回路首先设置偏移值，该偏移值用于遍历搜索和重放以控制伺服环路中均衡器的增益。 通过首先将拾取头移动到盘的径向中心位置并读取在该位置处记录的时间码地址数据来确定偏移值。 将读取地址与计算的预期地址进行比较，以确定两个是否在给定距离内。 如果它们是，则将偏移设置为预定值，例如为零。 如果它们不在给定距离内，则偏移量由两种方式之一决定。 或者使用差值作为偏移，或者将拾取头移动到盘的数据部分的最内周，并且将从其读取的地址数据用作偏移。 在搜索和重放期间，从连续读取的地址数据中减去偏移量，差值控制均衡器的增益。
