摘要： A camera system including a photoelectric convertor including a first and second electrode, and a photoelectric conversion layer; and a correction circuit correcting a signal corresponding to a potential change of the second electrode. The photoelectric convertor has a photoelectric conversion characteristic in which rate of change of the photoelectric conversion efficiency with respect to a first bias voltage between the first electrode and the second electrode when the first bias voltage is in a first voltage range, is greater than the rate of change with respect to a second bias voltage when the second bias voltage is in a second voltage range that is higher than the first voltage range, and a bias voltage between the first electrode and the second electrode exists in the first voltage range, and the correction circuit corrects the signal so that variation of an output regarding an amount of incident light becomes linear.

摘要： A spatial light modulator includes a photosensor diode and a photoemitting diode array, each having two semiconductive layers of opposite electrical polarities, and which are sandwiched together with layers of the same polarity (P or N) in electrical contact with each other. Transparent electrode layers are formed on the opposite surfaces of the photosensor diode and photoemitting diode array respectively, in electrical contact with the layers of the opposite polarity. The individual photoemitting diodes are electrically and optically isolated from each other. With a voltage applied across the electrodes which causes the photosensor diode to be reverse biased and the photoemitting diodes to be forward biased, the photoemitting diode array generates a visual display which is a reproduction of a light image incident on the photosensor diode. The photosensor diode may be replaced by a single layer of a photoconductive material. Two of the spatial light modulators may be combined in a frame with suitable optics to provide eye protection goggles.

摘要： An optical sensor module has a light receiver and a light-emitter which is surrounded by a light blocking wall, wherein the light receiver is disposed on a main plate and the light-emitter is disposed on a side plate separately from the main plate. The light blocking wall is formed as a light barrier wall between the light receiver and the light-emitter. A projecting portion projecting upward from the main plate is enclosed by the light barrier wall, and a top face of the projecting portion is higher than the light receiving face and the light-emitting face.
