Abstract
A communication device for an image pickup apparatus having its imaging lens focussing light input from a field on an image sensor uses infrared rays. An infrared ray receiving member is positioned in front of the image sensor for receiving infrared rays contained in the light transmitted through the lens. A detecting circuit detects a signal exclusive for communication contained in the infrared rays received. The infrared rays receiving member transmits visible rays so that the visible rays are incident on the image sensor.
Claims4
A communication device using infrared rays for use in an image pickup apparatus having a lens focussing light input from a field on an image sensor, comprising:
- an infrared rays receiving member positioned in front of the image sensor for receiving infrared rays contained in the light transmitted through the lens;
- and
- a detecting circuit for detecting a signal exclusive for communication contained in the infrared rays received;
- said infrared rays receiving member transmitting visible rays to thereby cause the visible rays to be incident on the image sensor.
