Solid-state imaging element, driving method, and electronic device

A driving method for a solid-state imaging element, the method comprising:

• setting a first driving line of the solid-state imaging element to a floating state, wherein
• the first driving line is configured to supply selectively to a posterior stage, a first voltage level output from a first power source and a second voltage level output from a second power source, and
• the second voltage level is lower than the first voltage level;
• lowering a third voltage level to be supplied to a second driving line of the solid-state imaging element, wherein
• the second driving line is different from the first driving line, and
• a capacitance is formed between the first driving line and the second driving line;
• and
• supplying a fourth voltage level to the posterior stage from the first driving line set to the floating state,
• wherein the fourth voltage level is supplied to the posterior stage based on a change in voltage supplied to the second driving line by capacitive coupling, and
• the fourth voltage level is between the first voltage level and the second voltage level.
