Solid-state imaging device, method for driving solid-state imaging device, and electronic apparatus

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

• a pixel part having a pixel arranged therein, the pixel performing photoelectric conversion;
• and
• a reading circuit having an analog-to-digital conversion function for analog-to-digital converting a pixel signal read out from the pixel to a signal line,
• wherein the reading circuit includes:
• an amplifying part for amplifying the pixel signal;
• and
• an AD converting part for analog-to-digital converting, in connection with a search signal, the pixel signal amplified by the amplifying part, and
• wherein the pixel signal read out from the pixel is at least either one of:
• a first pixel signal including a read-out reset signal and a read-out luminance signal that are read out in the stated order from the pixel in a first operation;
• and
• a second pixel signal including a read-out luminance signal and a read-out reset signal that are read out in the stated order from the pixel in a second operation, and
• wherein the search signal fed to the reading circuit is configured such that a first search signal for the first pixel signal and a second search signal for the second pixel signal are configurable such that search levels thereof are inverted.

An electronic apparatus comprising:

• a solid-state imaging device;
• and
• an optical system for forming a subject image on the solid-state imaging device,
• wherein the solid-state imaging device includes:
• a pixel part having a pixel arranged therein, the pixel performing photoelectric conversion;
• and
