摘要:
An endoscope processor comprising an image signal receiver, a calculator, an amplifier, and a noise reduction unit, is provided. The image signal receiver receives a raw image signal. The image signal is generated by an imaging device when the imaging device captures an optical image of an object. The calculator calculates a first gain. The first gain is used for amplifying the raw image signal. The amplifier amplifies the raw image signal based on the first gain, and then the amplified image signal is generated. The noise reduction unit reduces noise included in the amplified image signal according to the first gain, and then the noise-reduced signal is generated.
