Endoscope processor for noise reduction processing in endoscope system, has noise reduction unit that generates noise-reduced signal by reducing noise included in amplified image signal according to amplification gain

摘要

The endoscope processor (20) has an image signal receiver that receives raw image signal generated by an imaging device (41) when the imaging device captures an optical image of an object. Using a calculated gain, an amplifier generates an amplified image signal by amplifying the raw image signal. By reducing the noise included in the amplified image signal according to the gain, a noise reduction unit (33) generates a noise-reduced signal. An independent claim is also included for an endoscope system.
