Solid-state image sensing device and image sensing system

A solid-state image sensing device which can capture a moving image and a still image, comprising:

• a pixel array including a plurality of pixels;
• a vertical scanning circuit configured to select a row of said pixel array;
• a horizontal scanning circuit configured to select a column of said pixel array;
• a plurality of column signal lines to which signals from said pixel array are output;
• a plurality of first amplification units configured to amplify the signals output from said pixel array to said plurality of column signal lines;
• a plurality of signal holding units configured to hold the signals from said plurality of first amplification units;
• a plurality of switches configured to transfer the signals, which are held in said plurality of signal holding units, in accordance with a signal sent from said horizontal scanning circuit;
• a second amplification unit configured to amplify the signals transferred by said plurality of switches and output the amplified signals;
• a plurality of bypass routes configured to bypass said plurality of first amplification units between said plurality of column signal lines and said plurality of signal holding units;
• and
• a control unit configured to deactivate said first amplification units and bypass said first amplification units via said bypass routes in a moving image capturing mode, and to activate said first amplification units and shut off said bypass routes in a still image capturing mode.
