摘要： In one embodiment, a PLL circuit is provided with a plurality of pull-in operation modes for pulling a voltage across a filter capacitor (C1, C2) in a lock-up voltage, and with a register (CRG) for designating one of the plurality of pull-in operation modes. The pull-in operation is performed in accordance with a setting value in the register. Such a PLL may be used in a communication device such as a wireless portable phone which can operate in multiple frequency bands, e.g. GSM, DCS and PCS frequency bands. The PLL allows fast pull-in time in each frequency band and avoids locking the image frequency.

摘要： An image control apparatus in a television receiver, wherein after determining the frequency characteristic of an inputted video signal, when a high frequency band of the frequency characteristic has been raised above a predetermined level, the image quality is enhanced after performing waveform equalization on the video signal to cancel an impression of a dim image, given to the visual sense, and on the other hand, when the high frequency band of the inputted video signal has been lowered, noise reduction is performed after waveform equalization to further degrade the image quality for preventing deterioration of the S/N ratio, thereby usually providing appropriate images. The image control apparatus includes a waveform equalizer (101), a distorted waveform extraction control unit (102), a noise reduction circuit (103), and an image quality control unit (104). The waveform equalizer (101) receives an inputted video signal, equalizes waveform of the video signal, and outputs the waveform equalized video signal. The distorted waveform extraction control unit (102) detects distorted waveform from the output of the waveform equalizer and controls the waveform equalizer to perform waveform equalization suitable for the inputted video signal. It also controls the noise reduction circuit (103) and the image quality control unit (104) in accordance with changes in the frequency characteristic of the video signal before and after waveform equalization to intensify the noise reduction for degrading the image quality, when the high frequency band of the frequency characteristic of the input signal has been lowered, and, contrarily, to debilitate or stop the noise reduction for enhancing the image quality, when the high frequency band has been raised.
摘要翻译：一种电视接收机中的图像控制装置，其中，在确定了输入的视频信号的频率特性之后，当频率特性的高频带已经升高到高于预定电平时，在对视频进行波形均衡之后增强了图像质量信号以取消给予视觉的暗淡图像的印象，另一方面，当输入的视频信号的高频带已经降低时，在波形均衡之后执行降噪以进一步降低图像质量，以便防止S / N比的劣化，从而通常提供适当的图像。图像控制装置包括波形均衡器（101），失真波形提取控制单元（102），噪声降低电路（103）和图像质量控制单元（104）。波形均衡器（101）接收输入的视频信号，使视频信号的波形相等，并输出波形均衡视频信号。失真波形提取控制单元（102）从波形均衡器的输出端检测失真的波形，并且控制波形均衡器执行适合于输入的视频信号的波形均衡。它还根据波形均衡之前和之后的视频信号的频率特性的变化来控制降噪电路（103）和图像质量控制单元（104），以加强降低图像质量的降噪，当高输入信号的频率特性的频带已经降低，并且相反地，当高频带已经被提高时，为了提高图像质量而使噪声降低衰减或停止。

摘要： If information is to be recorded on and reproduced from a recording medium in correspondence between a code train in the form of a run-length-limited code and the positions of the leading edge and the trailing edge data of a status transition pattern such as pits, recording domains, a sync signal (24) is inserted at regular intervals in the information converted in the form of the run-length-limited code. The sync signal is constituted by a code train capable of deciding that the sync signal includes a code not existing in the conversion rule into a run-length-limited code during reproduction using a leading edge data (26) or trailing edge data (27) relative to the transition pattern (25).
