<p>PROBLEM TO BE SOLVED: To provide a light detecting device, a light receiving position detecting device, a coordinate input device, and a coordinate input and output device, and a light detecting method having a wide dynamic range. SOLUTION: Photoelectric transduction is performed by receiving the flashing light. A signal obtained by this photoelectric transduction is inputted, and is processed so that an output signal per one time lighting of the flashing light increases with the lapse of a flashing frequency with respective detecting periods as indicated in drawing 21, and the light is detected by this output signal.</p> |
