    • A video signal processing apparatus receives a video signal containing at least a luminance signal and a color difference signal. A trap filter attenuates a frequency band of the color difference signal to separate the luminance signal from the video signal. A bandpass filter attenuates a frequency band of the luminance signal to separate the color difference signal from the video signal. The trap filter is constituted by a switched capacitor filter that outputs the luminance signal with a delay time equivalent to a time difference between a delay time of the processing performed in a succeeding luminance signal processing circuit and a delay time of the processing performed in a color difference signal processing circuit. With this arrangement, the circuit scale of a filter circuit can be reduced and frequency characteristics of the filter can be stabilized.
    • 视频信号处理装置接收至少包含亮度信号和色差信号的视频信号。 陷波滤波器衰减色差信号的频带,以将亮度信号与视频信号分离。 带通滤波器衰减亮度信号的频带以将色差信号与视频信号分离。 陷波滤波器由开关电容滤波器构成,该开关电容滤波器输出亮度信号,其延迟时间等于在后续亮度信号处理电路中执行的处理的延迟时间与以颜色执行的处理的延迟时间之间的时间差 差分信号处理电路。 利用这种布置,可以降低滤波电路的电路规模,并且可以使滤波器的频率特性稳定。

    • A solar cell and photovoltaic power generation apparatus including a transparent electrically conductive film, a semiconductor provided on the transparent electrically conductive film, a conductive film opposing the semiconductor, and an electrolyte solution filled between the semiconductor and the conductive film. Metal ions, such as silver ions, may be dissolved in the electrolyte solution. When light is incident on the cell, the metal ions cause an oxidation-reduction reaction in the electrolyte solution and the cell is charged. When the open-circuit voltage decreases because the amount of incident light drops or light is blocked, the cell discharges to function as a secondary cell.
    • 一种太阳能电池和光伏发电装置,包括透明导电膜,设置在透明导电膜上的半导体,与半导体相对的导电膜,以及填充在半导体和导电膜之间的电解质溶液。 诸如银离子的金属离子可以溶解在电解质溶液中。 当光入射到电池上时,金属离子在电解质溶液中引起氧化还原反应,并且电池被充电。 当开路电压降低时,由于入射光的量下降或光线被阻挡,电池放电起二次电池的作用。
