    • An image pickup device is provided that comprises: a photoelectric conversion region; a driving circuit for reading out a signal generated by photoelectric conversion from an identical pixel contained in the photoelectric conversion region for a plurality of times; and a correction circuit for extracting a noise component by calculating a difference among a plurality of signals read out by the driving circuit and removing the noise component contained in the signals from the pixel using the extracted noise component.
    • 提供了一种图像拾取装置,包括:光电转换区域; 用于从光电转换区域中包含的相同像素读出多次光电转换产生的信号的驱动电路; 以及校正电路,用于通过计算由驱动电路读出的多个信号之间的差异并使用提取的噪声分量去除来自像素的信号中包含的噪声分量来提取噪声分量。

    • A display apparatus includes a CPU, an image display device, a light source for irradiating the image display device, a circuit for turning on/off the light source, a means for determining the resolution of the input image signal, a first switching means for turning on/off the power supply to the circuit components except the light source turning on/off circuit and a second switching means for turning on/off the power supply to the light source turning on/off circuit. In a first power-saving mode, the circuits may be opened by means of the first switching means after an appropriately selectable first predetermined period of time and may be opened by means of the second switching means after an appropriately selectable second predetermined period of time. A second power-saving mode is also provided for opening the first and second switching means by a combination of the polarity of the input horizontal synchronizing signal and that of the input vertical synchronizing signal. The first power-saving mode and the second power-saving mode may be used selectively.
    • 显示装置包括CPU,图像显示装置,用于照射图像显示装置的光源,用于打开/关闭光源的电路,用于确定输入图像信号的分辨率的装置,第一切换装置, 打开/关闭除了光源打开/关闭电路之外的电路部件的电源,以及用于打开/关闭光源打开/关闭电路的电源的第二切换装置。 在第一省电模式中,可以在适当选择的第一预定时间段之后通过第一开关装置打开电路,并且可以在适当选择的第二预定时间段之后借助于第二开关装置打开电路。 还提供了第二省电模式,用于通过输入水平同步信号的极性和输入垂直同步信号的极性的组合来打开第一和第二开关装置。 可以选择性地使用第一省电模式和第二省电模式。
