摘要： A photoelectric converter includes a first pn junction comprised of at least two semiconductor regions of different conductivity types, and a first field-effect transistor including a first source connected with one of the semiconductor regions, a first drain, a first insulated gate and a same conductivity type channel as that of the one of the semiconductor regions. The first drain is supplied with a second potential at which the first pn junction becomes zero-biased or reverse-biased relative to a potential of the other of the semiconductor regions. When the first source turns to a first potential and the one of the semiconductor regions becomes zero-biased or reverse-biased relative to the other semiconductor regions, the first pn junction is controlled not to be biased by a deep forward voltage by supplying a first gate potential to the first insulated gate, even when either of the semiconductor regions is exposed to light.

摘要： Expansion of the dynamic range was difficult in conventional amplifying photoelectric conversion devices designed to have a large gain because, when used for high input light intensity, the electric current exceeds the electric current capacity of a near-minimum sized transistor obtained with the design rules. Also, in conventional photoelectric conversion devices, techniques for varying the electric signal outputs in real-time at the device level are necessary for real-time import of observation targets or images having a high contrast ratio and for visualization of local areas in real-time. In order to solve this problem, the present invention provides a gain varying method, a variable gain photoelectric conversion device, a photoelectric conversion cell, a photoelectric conversion array, a read-out method thereof, and a circuit therefor in which amplifying photoelectric conversion devices and field-effect transistors are combined. By this means, varying gain of an output electrical signal in real-time and visualization of local areas of a captured image are possible, as well as expansion of the dynamic range of optical detection up to 11 digits.

In the present invention, in order to solve the problem, a photovoltaic cell has been configured with a combination of an amplified photovoltaic element (100) and a selection element (10 and the like) which are resistant to external noise, and various means of solution of the combination are provided which are resistant to the effects of address selection pulse noise at array readout time. As a result, a dynamic range of 6 to 7 orders of magnitude for light detection has become possible.
