    • The present invention provides a projecting apparatus including a driving portion which receives a predetermined signal to output a driving signal, a separating portion which separates a video signal into a horizontal synchronous signal and a vertical synchronous signal, a color correcting portion which adds a color correction to the horizontal synchronous signal and vertical synchronous signal to generate and output a color correction signal, multiple projection cathode ray tubes which receive the driving signal and the color correction signal to emit a light which is projected in accordance with the driving signal and which is subjected to the color correction by the color correction signal, and a display portion which receives the projected light to display a video. This configuration corrects the unevenness of colors from the multiple projection cathode ray tubes.
    • 本发明提供了一种投影装置,包括:接收预定信号以输出驱动信号的驱动部分,将视频信号分离为水平同步信号的分离部分和垂直同步信号;色彩校正部分, 对于水平同步信号和垂直同步信号以产生和输出颜色校正信号,接收驱动信号的多个投影阴极射线管和颜色校正信号发射根据驱动信号投射并被照射的光 通过颜色校正信号进行颜色校正,以及显示部分,其接收投影光以显示视频。 该配置校正了来自多个投影阴极射线管的颜色的不均匀性。
