摘要： Provided are a solid-state imaging device, a method for driving a solid-state imaging device, and an electronic apparatus capable of reading signals produced with different conversion gains and having different signal directions.
A pixel signal processing part 400 includes a first reading part 410 and a second reading part 420. Of a pixel signal PIXOUT input into an input node ND401, the first reading part 410 inverts the signal direction of a first-conversion-gain signal (HCGRST, HCGSIG) and outputs an inverted first-conversion-gain signal (HCGRST, HCGSIG), which has been subjected to inversion and amplification, to an AD converting part 430 via a connection node ND402. Of the pixel signal PIXOUT input into the input node ND401, the second reading part 420 keeps the signal direction of a second-conversion-gain signal (LCGSIG, LCGRST) unchanged, and outputs a non-inverted second-conversion-gain signal (LCGSIG, LCGRST) to the AD converting part 430 via the connection node ND402.

摘要： In a pixel signal processing part, a first input switch and an output switch are turned on and off in phase. When the first input switch and the output switch are ON and the second input switch is OFF, a first auto-zero switch and a second auto-zero switch are kept in the ON state to connect the second node to the reference potential (GND), so that a sampling capacitor, a feedback capacitor, and an auto-zero capacitor are operated in respective operation ranges of the capacitors, and the feedback capacitor is kept constant according to a difference of the input pixel signals, thereby making the output of the amplifier in linear response to the input signal.

摘要： A solid-state imaging device, a method for driving a solid-state imaging device and an electronic apparatus are capable of reducing kTC noise of a LCG signal, preventing a drop in SNR at the conjunction point between a HCG signal and the LCG signal, and eventually achieving improved image quality. At a start of a reset period, first and second reset transistors are switched into a conduction state. During a predetermined first period after the reset period starts, the first reset line is kept connected to a reset potential. After the first period elapses, the second reset transistor is switched into a non-conduction state to switch the first reset line into a floating state, so that the first reset line has high impedance. After a second period elapses and when the reset period ends, the first reset transistor is switched into the non-conduction state.

摘要： A solid-state imaging device includes a pixel part, a reading part for reading a pixel signal from the pixel part and a response data generating part including a fuzzy extractor. The response data generating part generates response data including a unique key in association with at least one selected from among variation information of pixels and variation information of the reading part. The response data generating part generates, when regenerating a key, a unique key using helper data acquired in generation of an initial key, variation information acquired in the regeneration of the key, and reliability information determined based on the variation information acquired in the regeneration of the key.

摘要： A fuzzy extractor includes an initial key generating part including a true random number generator, and a key regenerating part. The true random number generator generates a true random number using a read-out signal read from the reading part or a pixel signal read from the pixels of the pixel part in a true random number generation mode. The initial key generating part generates helper data and an initial key based on the true random number generated by the true random number generator and variation information acquired as a response when the initial key is generated. The key regenerating part generates, when a key is regenerated, a unique key based on helper data acquired when the initial key is generated and variation information acquired as a response including an error when the key is regenerated.
