Claims
- 1. A video processing unit for an endoscope, comprising:first and second image signal processing circuits, each of said image signal processing circuit being capable of receiving an image signal transmitted from an image receiving element of an endoscope, said first image signal processing circuit processing an image signal representing a color image, and said second image processing circuit processing an image signal representing a fluorescent image, wherein said second image signal processing circuit integrates a plurality of frames corresponding to light having a predetermined wavelength range to generate one frame of a video signal, said frame of said video signal having a brightness higher than a brightness corresponding to each of said image signals.
- 2. The video processing unit according to claim 1, wherein said first image signal processing circuit receives image signals representative of a plurality of frames corresponding to a plurality of components of light, said first image signal processing circuit outputting a frame of a video signal.
- 3. The video processing unit according to claim 1, wherein said predetermined wavelength range is a range between 500 nm and 600 nm.
- 4. The video processing unit according to claim 1, further comprising a video signal receiver that receives video signals output by said first and said second image signal processing circuits and outputs a signal which coincides with one of said video signals.
- 5. The video processing unit according to claim 4, wherein said video signal receiver that receives video signals output by said first and said second image signal processing circuits outputs a signal which is a combined signal of said video signals.
- 6. The video processing unit according to claim 1, a plurality of signal input terminals of said first and said second image signal processing circuits being provided independently from each other.
- 7. The video processing unit according to claim 1, further comprising:a manually operable switch; and an image synthesis circuit, wherein said first image signal processing circuit outputs a frame of a color image video signal to said image synthesis circuit, said second image signal processing circuit outputs a frame of a fluorescent video signal to said image synthesis circuit, and said image synthesis circuit outputs at least one of said color image video signal and said fluorescence image video signal.
