摘要：
Provided is a light detecting apparatus including: a first photoelectric converting unit which outputs a first electrical signal in accordance with an incident light including a modulated light component and a background light component; a filter unit which outputs a second electrical signal resulting from the modulated light component being reduced in the incident light; and a signal processing unit 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. In the light detecting apparatus described above, the photoelectric converting unit may include a first photoelectric converting element and a second photoelectric converting element each of which outputs the first electrical signal, the filter unit may attenuate the signal corresponding to the modulated light component in the first electrical signal output from the second photoelectric converting element, and the signal processing unit may subtract the second electrical signal from the first electrical signal output from the first photoelectric converting element.
