    • A camera control device and a method for operating a mobile terminal having a single camera module in selected modes to reduce the power consumption of the mobile terminal is disclosed. The camera control device for a mobile terminal includes a camera module, a memory, and a control unit. The camera module has a sensor for photographing an image. The memory stores tables which are provided for respective modes of the camera module and which include camera register values set for each mode and stores initial values of the sensor for the respective modes to initialize the sensor of the camera module. The control unit determines a mode of operating the camera module, extracts camera register values for the mode from a corresponding table stored in the memory, and operates the camera module according to the extracted camera register values to implement the corresponding mode.
    • 公开了一种相机控制装置和用于以选定模式操作具有单个相机模块的移动终端以减少移动终端的功耗的方法。 用于移动终端的相机控制装置包括相机模块,存储器和控制单元。 相机模块具有用于拍摄图像的传感器。 存储器存储为摄像机模块的各个模式提供的表,其包括为每个模式设置的摄像机寄存器值,并且存储用于各个模式的传感器的初始值以初始化摄像机模块的传感器。 控制单元确定操作相机模块的模式,从存储在存储器中的相应表提取模式的摄像机寄存器值,并根据提取的摄像机寄存器值操作摄像机模块以实现相应的模式。

    • Disclosed herein are an apparatus and method for measuring quality of an image received via a communication network. The apparatus includes an interface unit, a codec unit, a test image detection unit, and a Mean Opinion Score (MOS) measurement unit. The interface unit receives an image, including a start synchronization image and a test image via a communication network. The codec unit decodes the received image into a color signal. The test image detection unit detects any one value of brightness, saturation and hue information of the color signal input from the codec unit, calculates an average value for each frame, and detects the test image from the received image based on the calculated average value. The MOS measurement unit synchronizes the test image with a corresponding reference image, compares the quality of the test image with the quality of the reference image, calculates an MOS value based on the results of the comparison, and outputs the MOS value.
    • 这里公开了一种用于测量经由通信网络接收的图像的质量的装置和方法。 该装置包括接口单元,编解码器单元,测试图像检测单元和平均意见得分(MOS)测量单元。 接口单元通过通信网络接收包括起始同步图像和测试图像的图像。 编解码器单元将接收到的图像解码为颜色信号。 测试图像检测单元检测从编解码器单元输入的颜色信号的亮度,饱和度和色调信息中的任何一个值,计算每帧的平均值,并且基于所计算的平均值从接收到的图像检测测试图像。 MOS测量单元将测试图像与相应的参考图像同步,将测试图像的质量与参考图像的质量进行比较,基于比较结果计算MOS值,并输出MOS值。
