    摘要： A solid-state imaging device comprises a semiconductor substrate, a plurality of pixels formed on the semiconductor substrate and generating imaging signals, and an output amplifier converting a pixel signal generated from the pixel to an imaging signal, and outputting the image signal. The pixel includes a photoelectric converting portion generating a charge in accordance with the amount of received light, a capacitor storing a charge generated from the photoelectric converting portion, and a switching portion for reading out the charge stored in the capacitor as the pixel signal. The capacitor includes a storing region formed on at least one of a part or an adjacent portion of the photoelectric converting portion, a capacitor insulating film formed on the storing region, the capacitor insulating film being made of a high dielectric material having a high relative dielectric constant, and a capacitor electrode formed on the capacitor insulating film.

    摘要： In the exposure control circuit of an image input device according to the present invention, the rays of light from the subject pass through a diaphragm adjusting the amount of light and undergoes photoelectric conversion at a CCD imaging element. The image signal read from the CCD imaging element is accumulated more than once at an accumulating circuit. The luminance of the subject is detected at a luminance detector. Based on the detected luminance, a condition setting circuit sets the amount of incident light, exposure time, and the number of additions to suitable values. With those suitable settings, the amount of light through the diaphragm, the exposure time of the CCD imaging element, and the number of accumulations by the accumulating circuit are controlled so as to enable the subject to be photographed under the best condition.
