Optical sensor unit, optical sensor array, and method of driving optical sensor
First Claim
1. An optical sensor unit comprising:
- a plurality of radio optical sensor means each including an optical sensor and a radio element for transmitting and receiving of an information through communication with the optical sensor to and from an outside by radio; and
radio communication means for transmitting and receiving an electromagnetic wave as a radio signal to and from the radio elements, which is located in a region apart from the radio elements, wherein;
the radio communication means transmits to each of the radio elements an electromagnetic wave as a signal for requesting transmission of photographing information and an electromagnetic wave for supplying energy for photographing by the optical sensor and radio transmission and reception by the radio elements; and
each of the radio optical sensor means receives the electromagnetic waves and transmits photographing information of a subject from the optical sensor to the radio communication means through the radio element.

Abstract
To provide an optical sensor unit in which the respective optical sensor elements can be easily provided on a curved surface without using wirings, a reduction in image pickup speed due to wiring delay is prevented to improve a photographing speed, and highly sensitive photographing is realized. The optical sensor unit is composed of an image pickup area section in which a large number of radio optical sensors are arranged and a radio communication means located in the vicinity thereof. The radio communication means has an image data signal circuit, a radio transmission circuit connected therewith, and an antenna. Each of the radio optical sensors is composed of an optical sensor element, a radio element, and an antenna.
