Abstract:
The present disclosure relates to a solid-state image pickup device and an electronic apparatus that enable the performance of a logarithmic sensor in a solar-cell mode to improve. After Signal (S) is read, a P-phase signal (N) is read in a conducted state in which RST is ON, and a P-phase signal (N′) is read in a non-conducted state in which the RST is OFF. Thus, in a case where sufficient incident light illuminance is provided (Bright), S−N being the difference with respect to the P phase acquired in the conducted state in which the RST is ON, is selected and output. In a case where capacitance is insufficiently charged in a low-illuminance condition in which the incident light is less in amount (Dark), S−N′ being the difference with respect to the P phase acquired in the conducted state in which the RST is OFF, is selected and output. The present disclosure can be applied to, for example, a CMOS solid-state image pickup device used for an image pickup device, such as a camera.

Claim (Index 9):
An electronic apparatus comprising:\n a solid-state image pickup device including:\n a plurality of unit pixels arranged regularly and two-dimensionally, each of the plurality of unit pixels including:\n a photodiode including a first semiconductor region having a first conductivity type and a second semiconductor region having a second conductivity type, the second semiconductor region having majority carrier concentration higher than majority carrier concentration of the first semiconductor region, the second conductivity type being a conductivity type opposite to the first conductivity type; \n a reset transistor configured to operate to reset the photodiode; \n an amplifier transistor electrically connected to the second semiconductor region; and \n a signal line connected with the amplifier transistor directly or through an active terminal; and \n \n a driving circuit configured to drive each of the plurality of unit pixels such that a reset level corresponding to a signal level output to the signal line is acquired in two states being a conducted state and a non-conducted state of the reset transistor; \n a signal processing circuit configured to process an output signal output from the solid-state image pickup device; and an optical system configured to cause incident light to be incident on the solid-state image pickup device.
