摘要:
A photoelectric conversion device prevents a pseudo signal caused by the parasitic capacitance of a transfer switch from being input to an amplifier. A photoelectric conversion device (50) includes a pixel (10) which outputs a signal to a signal line (107), an amplifier which amplifies the signal supplied via the signal line (107), and an isolation switch (121) inserted between a signal line (108) and the input node of the amplifier. The pixel (10) includes a photodiode, a floating diffusion (FD), a transfer switch which transfers the charge of the photodiode to the FD, and an amplification transistor which outputs a signal to a signal line (109) in accordance with the potential of the FD. The isolation switch (121) is turned off at least in a period when a transfer pulse for controlling the transfer switch of the pixel (10) transits.
