Abstract
A camera provided with a distance measuring system having an infrared light emitting element, and an infrared light receiving element. The infrared light emitted by the emitting element and reflected by an object is received by the light receiving element, and based on a point where the reflected infrared light is incident to the light receiving element, an object distance is determined. In such a camera, the light emitting element is used for sending data by emitting a modulated infrared light. Similarly, the light receiving element is used for receiving data. Further, the light emitting angular range is changed in accordance with whether the emitted light is used for distance measuring or the data transmission.
