    • A method for generating a reduced image of an original image in which macroblocks are adaptively encoded, and an image apparatus thereof are provided. The method including extracting an average of compression blocks of current super macroblocks contained in a compression image, the compression image being encoded by intra prediction; computing an average of prediction blocks, using a portion of components of previous super macroblocks and a portion of components of blocks neighboring the prediction blocks corresponding to the compression blocks, if an encoding technique of the current super macroblocks is different from an encoding technique of the previous super macroblocks at a left edge of the current super macroblocks; and generating a reduced image using the average of the compression blocks and the average of the prediction blocks. The apparatus includes an extractor; a computation part; and an adder.

    • A test apparatus for a display apparatus having a display part to display an image thereon, the test apparatus including a PWM signal generator to receive an external video signal, and output a PWM signal; a clock signal generator to generate a system pixel clock signal based on the PWM signal output from the PWM signal generator, and output the generated system pixel clock signal to the display part; and a controller to control the PWM signal generator to sequentially adjust the frequency of the PWM signal output from the PWM signal generator. Thus, the test apparatus and method can test whether a display apparatus normally displays an image based on an external video signal if the frequency of the external video signal is deviated from a standardized frequency within predetermined limits.
    • 一种用于显示装置的测试装置,具有在其上显示图像的显示部分,所述测试装置包括用于接收外部视频信号的PWM信号发生器,并输出PWM信号; 时钟信号发生器,用于基于从PWM信号发生器输出的PWM信号产生系统像素时钟信号,并将生成的系统像素时钟信号输出到显示部分; 以及控制器,用于控制PWM信号发生器以顺序地调节从PWM信号发生器输出的PWM信号的频率。 因此,如果外部视频信号的频率偏离预定限度内的标准化频率,则测试装置和方法可以测试显示设备是否正常地基于外部视频信号显示图像。
