摘要: PROBLEM TO BE SOLVED: To enable an amplification factor to be adjusted while reducing the effect of quantization error a pixel signal, and suppress noise column amplifiers that becomes problem in case. SOLUTION: A photoelectric conversion apparatus is provided which includes plurality elements (201) arrayed matrix shape for generating signals through conversion; (209, 210) each element one or more columns amplifying generated by elements; analog/digital converters (213, 214) converting amplified from analog into digital, characterized controlled columns.
