摘要： In a DVD player, when data information in a DVD disk is played back, it is judged whether the data information is protected by a copyright or not on the basis of disk control information. Further, it is judged whether the DVD disk is writable or not, based on whether the DVD disk is provided with a wobble or not. Thus, if the data information is protected by the copyright and the DVD disk is writable, a playback of the DVD disk is prevented so that an illegal use of the DVD disk, which infringes the copyright, is effectively prevented.
摘要翻译：在DVD播放机中，当DVD盘中的数据信息被重放时，基于盘控制信息来判断数据信息是否受版权保护。此外，基于DVD盘是否被提供摆动来判断DVD盘是否可写入。因此，如果数据信息被版权保护并且DVD盘是可写的，则防止DVD盘的重放，从而有效地防止侵犯版权的DVD盘的非法使用。

摘要： An LCD apparatus has a control circuit 40 which makes a timing of the rear edges of scanning pulses provided to predetermined scanning lines coincide with the time when the display potential is renewed, wherein each of the predetermined scanning lines corresponds to an addition of a picture line to a picture or a reduction from two picture lines to one picture line on a picture in order to compensate for a difference between the number of scanning lines of the LCD and the number of lines of the picture to be displayed. In the control circuit, a circuit detects cycle times of the vertical and horizontal sync pulses, an MPU determines the reference value REF on the basis of the detected value and count CH of the horizontal sync pulse *HS from a counter, and a circuit generates a signal AE which makes the time when the pulse count CD of pixel clock CLKD from the counter becomes equal to the REF that coincides with the timing of the rear edge of scanning pulse.

摘要： In order to correct the change in the offset and amplitude of a tracking error signal because of the change in the position of an object lens from the center of an optical pickup, the offset amount and amplitude value of the tracking error signal with respect to the displacement amount of the object lens from the center of the optical pickup are checked beforehand, and the displacement amount of the object lens is estimated on the basis of a tracking correction signal by using an object lens displacement observer. An offset detection section and an amplitude detection section detect the offset amount and amplitude value of the tracking error signal respectively, and the tracking error signal is corrected by an offset correction circuit and an amplitude correction circuit on the basis of the offset amount and amplitude value having been checked beforehand so that the offset amount and the amplitude value of the tracking error signal become identical to those obtained when the displacement amount of the object lens is zero. In addition, the offset of the tilt error signal depending on the movement direction of the optical pickup 2 is detected and recorded beforehand, and the tilt error signal is corrected on the basis of the above-mentioned recorded offset when a rotation direction detection section detects the moving direction of the optical pickup.

摘要： A liquid crystal module comprises a liquid crystal panel including mutually orthogonal row electrodes and column electrodes and a liquid crystal layer sealed between the electrodes as a display element, a row electrode driving circuit driving the row electrodes of the liquid crystal panel, and a column electrode driving circuit driving the column electrodes. A detecting electrode detects scanning signals applied to the row and column electrodes of the liquid crystal panel by electrically coupling to the electrodes with electrostatic coupling capacity. A coordinate detecting circuit converts the signals obtained from the detecting electrode into row and column coordinates. A correction arithmetic circuit corrects positional differences by using correction parameters of the device which have been obtained from output values of the coordinate detecting circuit beforehand. The display-integrated coordinate input device improves detection precision at the edges of a matrix panel.

Each pixel is provided with an storage capacitor, wherein capacitors for stabilizing the voltage are added to the common storage capacitor bus line that applies a predetermined potential to the storage capacitor bus lines provided for each of the rows to absorb noise that mixes into the storage capacitor bus lines through parasitic capacitances, thereby to decrease fluctuation in the voltage of the storage capacitor bus lines and to prevent the occurrence of display unevenness and crosstalk.
