Light source magnifying power information, believe that the portion GCA 52 by image according to magnifying power corresponding with light source information acquired in acquisition unit 661
Breath amplification, but can also for example be arranged the enlarging section of multiple enlarged drawing signals in endoscope 2, to enlarging section be adjusted with
Making the magnifying power of these enlarging sections becomes magnifying power corresponding with light source information acquired in acquisition unit 661.Certainly, amplification control
Portion 662 respectively can also carry out the picture signal of simulation with decentralised control transmission buffer 23, reception amplifier 51 and the portion GCA 52
The magnifying power of amplification, to become magnifying power corresponding with light source information acquired in acquisition unit 661.
Also, in embodiments of the present invention 2, amplification control unit 662 is recorded referring to light source magnifying power record portion 551
Light source magnifying power information, believe that the portion GCA 52 by image according to magnifying power corresponding with light source information acquired in acquisition unit 661
Breath amplification, but such as amplification control unit 662 is also referred to the light source magnifying power letter that light source magnifying power record portion 551 is recorded
Breath, make image processing part 63 according to magnifying power corresponding with light source information acquired in acquisition unit 661 by number picture signal
Amplification.
