    • Provided are a color to grayscale image conversion method of converting a color image into a grayscale image while maintaining original features of the color image, and a recording medium storing a program for performing the same. When an original color image is input, a target gradient with the features of the input original color image is acquired, and a global mapping function for converting the original color image into a grayscale image is determined based on the acquired target gradient. Thereafter, the original color image is converted into a grayscale image using the determined global mapping function. Therefore, it is possible to quickly convert a color image into a grayscale image, and to acquire a high-quality grayscale image with features of color difference included in the original color image.
    • 提供了一种将彩色图像转换为灰度图像同时保持彩色图像的原始特征的彩色到灰度级图像转换方法,以及存储用于执行该彩色图像的程序的记录介质。 当输入原始彩色图像时,获取具有输入原始彩色图像的特征的目标梯度,并且基于所获取的目标梯度来确定用于将原始彩色图像转换为灰度图像的全局映射功能。 此后,使用所确定的全局映射函数将原始彩色图像转换成灰度图像。 因此,可以将彩色图像快速转换为灰度图像,并且获得具有包括在原始彩色图像中的色差特征的高质量灰度图像。

    • A plasma display device includes a plasma display panel and a controller for receiving a digital image signal corresponding to an image to be displayed during a frame. The controller time divides a frame into a plurality of subfields, generates control signals for driving the respective subfields at an initialization period, an address period, and a sustain discharging period, and generates switching signals corresponding to the respective subfields. The plasma display device also includes a driver for generating different levels of voltages in accordance with the switching signals, and for providing display data with the generated voltages in accordance with the control signals to the plasma display panel. The plasma display device may also generate switching signals corresponding to the temperature sensed by a temperature sensor.
    • 等离子体显示装置包括等离子体显示面板和用于接收与在帧期间显示的图像相对应的数字图像信号的控制器。 控制器时间将帧划分成多个子场,产生用于在初始化周期,地址周期和维持放电周期中驱动各个子场的控制信号,并产生与各个子场对应的切换信号。 等离子体显示装置还包括用于根据切换信号产生不同电平的驱动器的驱动器,并且用于根据等离子体显示面板的控制信号向显示数据提供产生的电压。 等离子体显示装置还可以产生对应于由温度传感器感测的温度的开关信号。
