Solid-state image pickup apparatus having effective and non-effective pixel portions, and driving method therefor

A solid-state image pickup device comprising:

• an effective-pixel portion in which effective pixels including photoelectric conversion units that convert incident light into charge are arranged in a matrix;
• a non-effective-pixel portion in which non-effective pixels that include no photoelectric conversion unit are arranged in at least one row;
• and
• a vertical scanning unit that selects the pixels arranged in the effective-pixel portion and the non-effective-pixel portion on a row-by-row basis,
• the solid-state image pickup device outputting first signals based on the effective-pixel portion and second signals based on the non-effective-pixel portion,
• wherein the solid-state image pickup device further includes an input section that receives, from outside, a third signal for switching between driving modes of the solid-state image pickup device, and
• wherein the vertical scanning unit starts performing electronic shutter scanning on the pixels arranged in the effective-pixel portion and causes only the second signals to be output immediately after the input section has received the third signal until the first signals are output.
