Abstract:
1. An electronic endoscope, comprising: a video-scope with an image sensor; a signal processor that generates digital component video signals from image-pixel signals that are read from said image sensor; a color-reverse detector that determines whether a color-reverse occurs in the digital component video signals; and a color correcting processor that changes color signal data associated with the color-reverse so as to correct the color-reverse when the color-reverse occurs, wherein said signal processor converts red-, green-, and blue-color digital video signals obtained from the image-pixel signals to luminance and color difference digital component video signals, said color-reverse detector determining whether color difference data in the luminance and color difference digital component video signals are switched, said color correcting processor replacing the order of data in the data array in the color difference data, said color-reverse detector inputs a pseudo signal for detecting the color-reverse to said signal processor, said color-reverse detector determining whether color difference data obtained from the pseudo signal are switched, and said color-reverse detector interleaves the pseudo signal at a head position of one line-worth of red, green, and blue digital video signals, said color correcting processor replacing the color difference data that follow the pseudo signal.
