Abstract
Provided is a light detecting apparatus including: a first photoelectric converting element which outputs a first electrical signal in accordance with an incident light including a modulated light component and a background light component; a filter which outputs a second electrical signal resulting from the modulated light component being reduced in the incident light; and a signal processor which subtracts the second electrical signal from the first electrical signal to reduce a component corresponding to the background light component in the first electrical signal.

A light detecting apparatus comprising:
- a photoelectric converting element which outputs a first electrical signal in accordance with an incident light including a modulated light component and a background light component;
- a filter which outputs a second electrical signal resulting from a signal corresponding to the modulated light component being attenuated in the first electrical signal;
- and
- a signal processor which subtracts the second electrical signal from the first electrical signal to reduce a signal corresponding to the background light component in the first electrical signal.
