摘要： In a signal processing device of an embodiment, an integration circuit accumulates a charge from a photodiode in an integrating capacitor element, and outputs a voltage value according to the amount of charge. A comparator circuit, when the voltage value from the integration circuit has reached a reference value, outputs a saturation signal. A charge injection circuit, in response to the saturation signal, injects an opposite polarity of charge into the integrating capacitor element. A counter circuit performs counting based on the saturation signal. A holding circuit holds the voltage value from the integration circuit. An amplifier circuit outputs a voltage value that is K times (where K>1) larger than the voltage value held by the holding circuit. An A/D converter circuit sets a voltage value that is K times larger than the reference value as the maximum input voltage value, that is, a full-scale value, and outputs a digital value corresponding to the voltage value from the amplifier circuit.

摘要： A pixel circuit has first, second, and third field effect transistors integrated and connected in series from a photoelectric conversion element to a side of an amplifier circuit. The first and second field effect transistors have gate electrodes to be simultaneously collectively driven. A threshold voltage of the first field effect transistor is set to be higher than that of the second field effect transistor. As the gate electrodes are driven step by step, electrons generated by the photoelectric conversion element and transferred via the first field effect transistor are accumulated in a channel region of the second field effect transistor. The electrons accumulated in the channel region are transferred to an input of the amplifier circuit via the third field effect transistor.

摘要： A solid-state imaging device includes a photodetecting unit, a row control unit, a column control unit, and a signal readout unit. The photodetecting unit includes M×N pixel units P(1,1) to P(M,N) two-dimensionally arrayed in M rows and N columns. Each pixel unit P(m,n) includes a photodiode PD, an amplifying transistor Tr1, a transfer transistor Tr2, a readout transistor Tr3, a first initialization transistor Tr4, and a second initialization transistor Tr5. One of the transfer transistor Tr2 and the first initialization transistor Tr4 performs an on/off operation based on a control signal output from the row control unit, and the other performs an on/off operation based on a control signal output from the column control unit. Thus, a solid-state imaging device capable of setting an accumulation period of various patterns different for each pixel is realized.
