Ranging system and non-transitory recording medium

A ranging system comprising:

• a light projector to project projection light;
• multiple light-receiving elements to receive light including reflected light of the projection light reflected from an object, each of the multiple light-receiving elements having a light incident range including an overlapping region, the overlapping region overlapping the light incident range of another one of the multiple light-receiving elements;
• a temperature sensor to measure temperature of at least one of the multiple light-receiving elements and output temperature information indicating the temperature of at least one of the multiple light-receiving elements;
• and
• circuitry configured to:
• output distance information based on outputs from the multiple light-receiving elements;
• and
• correct the distance information using the temperature information and outputs from light-receiving areas of the multiple light-receiving elements corresponding to the overlapping region.

A non-transitory recording medium storing a plurality of program codes which, when executed by one or more processors, causes the one or more processors to perform a method, the method comprising:

• receiving outputs from three or more light-receiving elements receiving light reflected from an object, each of the three or more light-receiving elements having a light incident range including an overlapping region, the overlapping region overlapping the light incident range of another one of the multiple light-receiving elements, the three or more light-receiving elements having at least two overlapping regions;
• outputting distance information based on outputs from the three or more light-receiving elements;
• and
• correcting the distance information using outputs from light-receiving areas of the three or more light-receiving elements corresponding to the at least two overlapping regions.
