Abstract

PROBLEM TO BE SOLVED: To reduce the number of components and to make a device small without losing the performance of the camera. SOLUTION: An image of an object 401 is bent by a dichroic mirror 101, led to a lens mirror cylinder 402 and picked up via an optical low pass filter 417 with a CCD 403. Since the dichroic mirror 101 cuts off an infrared ray and has the characteristics to transmit a signal light from a remote controller, a conventional infrared ray cut-off filter is omitted and a remote control light receiving element 414 that receives the signal light is provided to an excess triangle space produced in the rear of the dichroic mirror 101 to make the device compact.
