摘要： A display device has a line scan driving circuit disposed in a horizontal direction of a display region and a pixel driving circuit (dot scan driving circuit) disposed in a vertical direction of the display for performing image display with pixel groups each forming one line in the vertical direction being scanned in the horizontal direction. Vertical-horizontal converting circuitry is provided for converting an image data stream supplied with n pixels in a horizontal direction and m horizontal lines in a vertical scanning direction into an image data stream with m pixels in a vertical direction and n vertical lines in a horizontal scanning direction, and the vertical-horizontal converted data is supplied to the display device by a display controlling circuit. That is, image data is supplied to the displaying device as a vertical-horizontal converted data stream and display operation is executed by vertical pixel rows being scanned in the horizontal direction, as a result of which the relatively small line scan driving circuit is disposed above or below the display region instead of the relatively large dot scan driving circuit and thus the area required for circuit mounting above/below the display region is reduced and the size of the display device in the vertical direction can be effectively reduced.
摘要翻译：显示装置具有沿显示区域的水平方向设置的行扫描驱动电路和沿着显示器的垂直方向设置的像素驱动电路（点扫描驱动电路），用于进行图像显示，每个像素组在每一个中形成一条线垂直方向在水平方向扫描。提供垂直 - 水平转换电路，用于将沿水平方向的n个像素提供的图像数据流和垂直扫描方向上的m个水平线转换为垂直方向上具有m个像素的图像数据流和在水平扫描中的n个垂直线方向，并且通过显示控制电路将垂直水平转换的数据提供给显示装置。也就是说，将图像数据作为垂直水平转换数据流提供给显示装置，并且通过在水平方向上扫描的垂直像素行执行显示操作，结果，相对较小的行扫描驱动电路设置在上方或低于显示区域，而不是相对较大的点扫描驱动电路，因此减小了显示区域上方/下方的电路安装所需的面积，并且可以有效地降低显示装置在垂直方向上的尺寸。

摘要： The invention provides a head mounted display apparatus and a voltage controlling method for the head mounted display apparatus by which supply of a power supply voltage to circuit components is controlled to reduce the power consumption. The head mounted display apparatus includes an image displaying section for being mounted on the head of a user and positioned in front of the eyes of the user, a power supply section for supplying a power supply voltage, and a control section for controlling the power supply voltage to be supplied from the power supply section. Whether or not the eyes of the user look away from an image formed by the image displaying section is detected from a portion of the head of user in the proximity of the eyes, and, when it is detected that the eyes of the user look away from the image display section, the supply of the power supply voltage to the image displaying section is interrupted while the detection operation remains operative by continued supply of the power supply voltage.

摘要： A detecting unit generates defference data between optical black level of digital input data and a predetermined black level and generates .gamma. characteristics selection signal. An offset signal obtained from the difference is added to the input data by an adding circuit. A .gamma. characteristics setting unit is supplied with the difference data and the output signal of the adding circuit and outputs a signal in which a white level, black level and .gamma. characteristics are corrected.

摘要： A key information management system includes one or more record reproduction apparatuses and a key information management server. Each record reproduction apparatus has a substrate which can be replaced, and a nonvolatile storage unit which is mounted on the substrate and stores substrate identification information and key information of an encryption key. The key information management server includes a storage unit for storing the substrate identification information and the key information of the substrate in association with product identification information of the record reproduction apparatus, and the key information management server permits access to the storage unit through authentication. The record reproduction apparatus accesses the key information management server through the authentication after the substrate is replaced, and then rewrites substrate identification information and key information of the substrate after the replacement using the substrate identification information and key information of the substrate before replacement.
