1. A photoelectric conversion apparatus comprising:
a plurality of pixels arranged in a matrix; and
a control circuit configured to control the plurality of pixels,
wherein each of the plurality of pixels include a photoelectric conversion unit configured to generate a signal charge, a floating diffusion unit, a transfer transistor configured to transfer the signal charge to the floating diffusion unit, and a transistor configured to be electrically connected to the floating diffusion unit,
wherein the control circuit outputs a row selection pulse configured to select the pixel arranged in a row direction, and a pixel control pulse having a rise time longer than a rise time of the row selection pulse, and
wherein the pixel control pulse is entered to a gate of the transistor.
