Abstract: PROBLEM TO BE SOLVED: To enable variations in offset values of a threshold voltage held by a source follower circuit to be corrected even though an offset value of every pixel existing within all over the whole pixel area is not stored into a memory.SOLUTION: A correcting circuit 44A, which performs a reset operation for correcting variations of the offset value of the threshold voltage held by the source follower circuit, is provided in every unit pixel 40A. Then, a voltage of an accumulation node N11 is reset to a voltage Vref+Vth before reading a signal by the reset operation performed by the correcting circuit 44A. Thus, the offset value included in a gate input voltage Vin at the time of reading the signal is canceled with the threshold voltage Vth of a transistor 42 for reading, because signal charge is accumulated relating to the accumulation node N11 with a state in which the offset value of the threshold voltage Vth of the transistor 42 for reading is added after the reset operation.
Abstract translation: 要解决的问题：即使在整个像素区域内存在的每个像素的偏移值不被存储到存储器中，也能够使由源极跟随器电路保持的阈值电压的偏移值的变化被校正。解决方案：A 在每个单位像素40A中设置校正电路44A，其执行用于校正由源极跟随器电路保持的阈值电压的偏移值的变化的复位操作。 然后，通过由校正电路44A执行的复位操作，在读取信号之前，累加节点N11的电压被复位为电压Vref + Vth。 因此，在读取信号时包括在栅极输入电压Vin中的偏移值被用于读取的晶体管42的阈值电压Vth消除，因为与累积节点N11有关的信号电荷是以 在复位操作之后添加用于读取的晶体管42的阈值电压Vth的偏移值。
