Abstract: A shape estimation device includes an input circuit, a storage circuit and an arithmetic circuit. The input circuit receives light amount information being a relationship between a wavelength and a light amount. The light amount information is acquired by using a sensor configured such that the light amount to be detected with respect to the wavelength corresponding to each of sensing parts varies in accordance with a shape of each of the sensing parts. The storage circuit stores a relationship among the shape, the wavelength and the light amount with respect to each sensing part. The arithmetic circuit calculates the shape of each sensing part, based on the light amount information, and a light amount estimation value being a relationship between the wavelength and the light amount.

Abstract: In an endoscope system, an imaging device is electrically connected to a signal line and is configured to output a video signal to the signal line. A receiver circuit is electrically connected to the signal line and is configured to receive the video signal. A noise detection circuit is configured to detect that noise having a higher frequency than a frequency of the video signal is mixed into the video signal. A filter circuit has a function of reducing the noise included in the video signal. An imaging control circuit is configured to set a signal-output time per one pixel of the imaging device to a second set time longer than a first set time and a filter control circuit is configured to turn on the function of the filter circuit when the noise is detected by the noise detection circuit.
