Claim 0:
1. An image pickup apparatus comprising:
an electrochromic element including a first electrode, a second electrode, and an electrochromic layer disposed between the first electrode and the second electrode, wherein
the electrochromic layer includes a solvent and an anodic redox substance and a cathodic redox substance dissolved in the solvent, and
at least one of the anodic redox substance and the cathodic redox substance is an electrochromic compound, where
the image pickup apparatus performing image processing based on a current flowing between the first electrode and the second electrode when a voltage lower than the voltage causing a substantial change in the transmittance of the electrochromic layer is applied between the first electrode and the second electrode.
