PROBLEM TO BE SOLVED: To provide a signal reading circuit achieving highly accurate reading, while reducing the circuit scale.SOLUTION: A signal reading circuit includes an input section to which a first signal and a second signal are inputted, a first holding capacity for holding a first signal inputted from the input section, a second holding capacity for holding a second signal inputted from the input section, and an amplifier circuit having an input terminal and an output terminal, and configured to be able to input the signal, held in the first holding capacity or second holding capacity, to the input terminal. In a period when the first signal is inputted from the input section to the first capacity, the first signal is also inputted to the input terminal of the amplifier circuit.SELECTED DRAWING: Figure 2 |
