Abstract
The reflection detection apparatus includes multiple light-receiving elements configured to detect a pattern formed on an object by receiving a reflected light from the object, and a selector configured to select a first light-receiving element group from the multiple light-receiving elements. The selector is configured to select the first light-receiving element group that includes one or more light-receiving elements each mainly receiving a specularly reflected light from an area of the object where no pattern is formed among the multiple light-receiving elements, on a basis of outputs from the multiple light-receiving elements. The detection of the pattern is made on a basis of an output from the first light-receiving element group.
