Abstract:
An image fiber imaging apparatus comprising:an image guide fiber bundle having a plurality of optical fibers, a receiving end, at which one ends of said optical fibers are arranged, and a transmitting end, at which other ends of said optical fibers are arranged, said receiving end being directed to an object to receive an image of said object, said optical fibers transmitting said image received at said receiving end to said transmitting end, said image including a plurality of image portions, each corresponding to one of said optical fibers; a solid-state imaging device arranged at said transmitting end of said image guide fiber bundle for converting said image including a plurality of image portions transmitted by said optical fibers of said image guide fiber bundle into an image signal; an electrical spatial filter for filtering said image signal converted by said solid-state imaging device to output a filtered image signal; and a display unit for displaying said filtered image signal outputted by said electrical spatial filter, in which said electrical spatial filter is selectively operative as a highpass filter and a lowpass filter.
