Solid-state imaging apparatus, drive method thereof, and imaging system

摘要: PROBLEM TO BE SOLVED: To provide a solid-state imaging apparatus adopting configuration wherein one common amplifier is employed for plurality of pixels that much more reduces the pixel read time. SOLUTION: The comprises arrangement units 1 each having photo diodes 4-1 (first line) and 4-2 (second by two lines an amplification MOS transistor 3 receiving signal electric charges providing output provided with circuit systems (22-1, 22-2 or like) connected to line 8 3. Each system receives first corresponding reset level gate potential transistor, second superimposing stored in diode on signal, third summing 4-1, takes difference between three signals their combinations.
