Solid-state imaging device and driving method of same

A driving method of a solid-state imaging device including

• a pixel array unit in which there are arrayed in a matrix form a plurality of pixels including
• a plurality of normal pixels which are pixels for video output, and
• a plurality of phase difference pixels which are pixels for focal-point detection,
• the method comprising:
• comparing pixel signals output from the pixels of the pixel array unit with a ramp signal serving as a reference signal, thereby performing A/D conversion on the pixel signals;
• and
• performing control so that the ramp signal to be compared with the phase difference pixels has a different slope from that of the ramp signal to be compared with at least a part of the normal pixels.

A solid-state imaging device comprising:

• a pixel array unit in which there are arrayed in a matrix form a plurality of pixels including
• a plurality of normal pixels which are pixels for video output, and
• a plurality of phase difference pixels which are pixels for focal-point detection;
• a selector unit configured to selectively output a first ramp signal and a second ramp signal;
• and
• an A/D conversion unit configured to compare pixel signals output from the pixels of the pixel array unit with a ramp signal output from the selector unit, thereby performing A/D conversion on the pixel signals.
