1. A solid-state imaging apparatus comprising:
a pixel array in which a plurality of pixels are arrayed; a plurality of processing units configured to process signals each being based on a signal which is output from each pixel on each column of the pixel array, wherein the plurality of processing units form a plurality of groups each including two or more processing units; an output line; a power supply line configured to transfer a power voltage;
a plurality of signal lines each corresponding to a different one of the plurality of groups, and each configured to connect to output nodes of the two or more processing units in the corresponding one of the plurality of groups; a plurality of connecting units each corresponding to a different one of the plurality of groups; and a control unit, wherein, in a case of outputting signals from the processing units in one group of the plurality of groups during a first period, the control unit, during the first period, controls the connecting unit of the one group, to connect the output line and the signal line of the one group electrically and to output the signals from the processing units in the one group, the control unit, during the first period, controls the connecting unit of another group, to connect the power supply line and the signal line of the another group electrically and to set an electrical path between the output line and the signal line of the another group, in a high impedance state, and each of the plurality of processing units includes a conversion unit configured to perform analog/digital conversion on the signals from the respective pixels and a signal holding unit configured to hold the signals from the conversion unit.
