Solid-state imaging apparatus and imaging system

A solid-state imaging apparatus having an imaging area formed by arranging a plurality of imaging blocks,

• each of the plurality of imaging blocks comprising:
• a pixel array in which a plurality of pixels are arranged to form a plurality of rows and a plurality of columns;
• a plurality of vertical signal lines provided in correspondence with the plurality of columns, respectively;
• a horizontal output line commonly provided for the plurality of vertical signal lines to read out signals read out to the plurality of vertical signal lines;
• a first scanning circuit;
• and
• a second scanning circuit,
• wherein signals of the pixels of a selected row in the pixel array are read out to the plurality of vertical signal lines in accordance with a driving pulse from the first scanning circuit,
• the signals read out to the plurality of vertical signal lines are sequentially read out to the horizontal output line in accordance with a driving pulse from the second scanning circuit, and
• a length in a row direction of the pixel array is smaller than a length in a column direction of the pixel array.
