    摘要： A solid state image sensor includes a semiconductor substrate where photoelectric conversion regions for converting light into charges are arranged per pixel planarly arranged; an organic photoelectric conversion film laminated at a light irradiated side of the semiconductor substrate via an insulation film and formed at the regions where the pixels are formed; a lower electrode formed at and in contact with the organic photoelectric conversion film at a semiconductor substrate side; a first upper electrode laminated at a light irradiated side of the organic photoelectric conversion film and formed such that ends of the first upper electrode are substantially conform with ends of the organic photoelectric conversion film when the solid state image sensor is planarly viewed; and a film stress suppressor for suppressing an effect of a film stress on the organic photoelectric conversion film, the film stress being generated on the first upper electrode.

    摘要： An imaging device with low power consumption is provided. A pixel includes a first circuit and a second circuit. The first circuit can generate imaging data and retain difference data that is a difference between the imaging data and data obtained in an initial frame. The second circuit includes a circuit that compares the difference data and a voltage range set arbitrarily. The second circuit supplies a reading signal based on the comparison result. With the use of the structure, reading from the pixel is not performed when it is determined that the difference data is within the set voltage range and reading from the pixel can be performed when it is determined that the difference data is outside the voltage range.

    摘要： An imaging device includes a semiconductor substrate, an impurity region, a first transistor, and a second transistor. The impurity region is located in a semiconductor substrate. The impurity region holds electric charge generated through photoelectric conversion. The first transistor includes a first source, a first drain, a first gate, and a first gate-insulating film. One of the first source and the first drain includes the impurity region. The first gate is electrically connected to the impurity region. The first gate-insulating film is located between the first gate and the semiconductor substrate. The second transistor includes a second gate and a second gate-insulating film. The second gate is electrically connected to the impurity region. The second gate-insulating film is located between the second gate and the semiconductor substrate. The thickness of the first gate-insulating film is greater than the thickness of the second gate-insulating film.
