発明の名称 (英語) SENSOR INTEGRATED CIRCUIT
発明の概要(英語) A sensor integrated circuit able to shorten the signal transmission time from a sensor circuit to a signal processing circuit, without detracting from the accuracy of the final value. The sensor circuit (13) has an output resistance (Rs) and includes an output (13a), which is connected to a signal line (19), and an image sensor pixel (21). The signal processing circuit (15) is connected via the signal line (19) to the output of the sensor circuit (13). The signal processing circuit (15a) includes an input (16a) having a first input capacitance value, and processes signals received from the sensor circuit (13) through the signal line (19). A charging circuit (17) includes an output (17a), input (17b) connected to the signal line (19). The output resistance (R2) of the output (17a) is lower than the output resistance (Rs), and the input capacitance value of the input (17b) is lower than the first input capacitance value. The charging circuit (17) begins charging the signal line (19) via the output (17a) in response to the potential (VCOL) at the input (17b), and ends charging at the time (t2) before the time (t1) of the end point of the driving period TDRV.
