Solid-state image pickup apparatus signal processing method for a solid-state image pickup apparatus, and electronic apparatus
First Claim
1. A solid-state image pickup apparatus, comprising:
- a pixel array section in which a unit pixel including a photoelectric conversion section and a charge detection section for detecting charge generated by photoelectric conversion by said photoelectric conversion section is disposed;
a driving section adapted to carry out driving of reading out a signal of said unit pixel divisionally by twice as a first signal and a second signal; and
a signal processing section adapted to set the first signal read out first from said unit pixel as a reference voltage for a processable input voltage range of said signal processing section, adjust the reference voltage so that the first and second signals may be included in the input voltage range and carry out signal processing for the first and second signals using the adjusted reference voltage.
