  • Patent number: 10757350
    Abstract: 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.

  • Patent number: 10412329
    Abstract: An imaging apparatus with logarithmic characteristics includes: a photodiode that receives light; a well tap unit that fixes the potential of an N-type region of the photodiode; and a resetting unit that resets the photodiode, a P-type region of the photodiode outputting a voltage signal equivalent to a photocurrent subjected to logarithmic compression. The first potential to be supplied to the well tap unit is made lower than the second potential to be supplied to the resetting unit, so that the capacitance formed with the PN junction of the photodiode is charged when the resetting unit performs a reset operation. The present technology can be applied to unit pixels having logarithmic characteristics.
