摘要:
An imaging apparatus capable of reducing a line noise artifact in a simple configuration without complicated operations includes: a plurality of pixels arranged in row and column directions and having a photoelectric conversion element and a switch element; a plurality of signal wirings connected to the plurality of switch elements in the column direction; a read-out circuit connected to the plurality of signal wirings; and a power source for supplying a voltage to the photoelectric conversion element. With the configuration, the plurality of pixels are classified into a plurality of groups, and the power sources are independently provided for each of the plurality of groups.
