    • Image analysis apparatus comprises a two dimensional array of photodetectors (80) for receiving light from pixels of a display screen (90). The intensity values generated by the photodetectors (80) in response to incident light from the pixels are stored in a memory (40). The photodetectors' spatial geometry is mapped onto the display screen's known pixel geometry. A processor (50) determines one or more performance parameters of the display screen (90) as a function of the intensity values stored in the memory (40) and of the photodetectors mapped spatial geometry (80). Calibration and correlation problems associated with prior art measurement techniques are avoided by mapping the spacing of the array of photodetectors onto the known geometry of the display pixel structure. Also, the apparatus can be conveniently incorporated into a handset and therefore does not require complicated positioning jigs in use.
    • 图像分析装置包括用于从显示屏(90)的像素接收光的光电检测器(80)的二维阵列。 由光电检测器(80)响应于来自像素的入射光产生的强度值被存储在存储器(40)中。 光电探测器的空间几何被映射到显示屏上已知的像素几何。 处理器(50)根据存储在存储器(40)和光电探测器映射的空间几何(80)中的强度值的函数来确定显示屏幕(90)的一个或多个性能参数。 通过将光电检测器阵列的间距映射到显示像素结构的已知几何形状来避免与现有技术测量技术相关的校准和相关问题。 此外,该装置可以方便地并入到手机中,因此不需要使用复杂的定位夹具。

    • A system and method for providing voice communications with desired characteristics based upon the intended recipient of a voice communication. An apparatus includes a list of dial strings associated with parties having desired voice communication characteristics. A dial string entered by a user and associated with an intended recipient is compared to a list of preferred dial strings to determine the characteristics of an encoded voice signal to be sent to the recipient. The apparatus can include a vocoder having different bit rate modes and a bit rate mode is selected based upon the dial string entered by a user. Dial strings can be stored at the device or on a network. The apparatus can include a mode selector to select a desired vocoder mode to generate an encoded voice signal.
    • 一种用于基于语音通信的预期接收者提供具有期望特征的语音通信的系统和方法。 一种装置包括与具有所需语音通信特性的方相关联的拨号串列表。 将由用户输入并与预期接收者相关联的拨号串与优选拨号串列表进行比较,以确定要发送给接收者的已编码语音信号的特征。 该装置可以包括具有不同比特率模式的声码器,并且基于用户输入的拨号串来选择比特率模式。 拨号字符串可以存储在设备或网络上。 该装置可以包括模式选择器,用于选择所需的声码器模式以产生经编码的语音信号。
