    • PURPOSE: An image display apparatus is provided to convert an analog image signal inputted from a television signal and a personal computer into a digital image signal and to display the digital image signal to a PDP(Plasma Display Panel) or an LCD(Liquid Crystal Display) panel, thereby obtaining an image with high contrast stably. CONSTITUTION: A video amplifier(3) amplifies the inputted analog luminance signal. An A/D(Analog/Digital) converter(5) converts analog image signal into digital image signal. A signal level detecting circuit(6) detects luminance information such as the maximum luminance level and an average luminance level from the digital image signal output by the A/D converter within a predetermined period. A microcomputer(7) controls the luminance component and color component of the image signal by using luminance information.
    • 目的:提供一种图像显示装置,用于将从电视信号和个人计算机输入的模拟图像信号转换为数字图像信号,并将数字图像信号显示给PDP(等离子体显示面板)或LCD(液晶显示器 )面板,从而稳定地获得高对比度的图像。 构成:视频放大器(3)放大输入的模拟亮度信号。 A / D(模拟/数字)转换器(5)将模拟图像信号转换为数字图像信号。 信号电平检测电路(6)在预定时间段内从由A / D转换器输出的数字图像信号中检测诸如最大亮度级和平均亮度级的亮度信息。 微型计算机(7)通过使用亮度信息来控制图像信号的亮度分量和颜色分量。
