Solid-state imaging device

A solid-state imaging device comprising:

• a plurality of unit pixels arranged in a row direction and a column direction;
• a plurality of vertical signal lines each connected to at least one of the unit pixels arranged in the column direction;
• a plurality of first converters connected to the respective vertical signal lines and converting an analog pixel signal appearing on the corresponding vertical signal line into a digital pixel signal in reading each unit pixel arranged in the row direction;
• an initialization voltage generator that outputs an initialization voltage for initializing the unit pixels or input nodes of the first converters;
• and
• an initialization voltage line that connects the initialization voltage generator and the first converters, wherein
• the initialization voltage generator changes the initialization voltage that is output for each row and/or column to be processed by the first converters, and
• the initialization voltage generator changes at least one of a voltage value of the initialization voltage and a control pulse width of a switch that applies the voltage for initializing the input nodes of the first converters, for each row and/or column to be processed by the first converters.
