Abstract
A coordinate detecting apparatus includes a plurality of light-receiving sensors and a controller. The plurality of light-receiving sensors detect light emitted from a light-emitting member in a detection area. The controller detects a position of the light-emitting member based on the light detected by the plurality of light-receiving sensors, and controls the light-emitting member such that an intensity of the light emitted from the light-emitting member is higher than an intensity of ambient light incident on the plurality of light-receiving sensors.
