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.
