Solid-state imaging device, driving method thereof, and imaging device

A method for driving a solid-state imaging device, the solid-state imaging device including:

• an imaging unit including pixel units arranged in rows and columns, the pixel units generating pixel signals each according to an amount of light received;
• a row select unit which selects at least one row of the pixel units;
• column signal lines which are respectively provided for the columns, and transmit pixel signals from the selected at least one row of the pixel units;
• amplifier circuits which are respectively provided for the columns, and each of which includes an input terminal and an output terminal, the input terminal being connected to a corresponding one of the column signal lines, each of the amplifier circuits outputting an amplified pixel signal through the output terminal;
• said method for driving the solid-state imaging device, comprising:
• detecting a switchover between a moving image capture mode for a monitor and a still image capture mode;
• switching each of the amplifier circuits ON when the switchover into the still image capture mode is detected;
• switching each of the amplifier circuits OFF when the switchover into the moving image capture mode for a monitor is detected;
• allowing a pixel signal to bypass from said input terminal to said output terminal of a corresponding one of said amplifier circuits when the switchover into the motion image capture mode for a monitor is detected;
• and
• mixing a predetermined number of pixel signals outputted from at least one said output terminal.
