Abstract: An estimation device includes a processor configured to: detect an error of data obtained by receiving a wireless signal from a medical device; correct the detected error; determine whether or not there is a noise due to an external generation source at a time of acquiring the wireless signal from the medical device, based on detection information relevant to the detected error or correction information relevant to the corrected error; and estimate a cause of the noise, based on the detection information or the correction information. The detection information is at least one of the number of detections of the error, continuousness of the error, and periodicity of the error, and the correction information is at least one of the number of corrections of the error, continuousness of data in which the error is corrected, and periodicity of data in which the error is corrected.

Abstract: A processing apparatus processes an image signal generated by pixels that have received light from an object irradiated with first wavelength light. The processing apparatus includes a processor having hardware. The processor is configured to: extract first and second image signals from the image signal of one frame generated by the pixels, the first image signal being generated by a pixel that has received the first wavelength light, the second image signal being generated by a pixel that has received second wavelength light that is fluorescence emitted in response to the first wavelength light; estimate an image signal to be generated by the pixel that has received the second wavelength light, based on the first image signal; and calculate a difference, on a corresponding image signal portion, between the second image signal and the estimated image signal, thereby to obtain a differential image signal.
