Abstract
An image pickup apparatus including an electrochromic element, wherein the electrochromic element includes a complementary-type EC layer including a solvent and an anodic redox substance and a cathodic redox substance dissolved in the solvent, and image processing is performed based on a charge imbalance current flowing between a first electrode and a second electrode when a voltage lower than the voltage causing a substantial change in the transmittance of the EC layer is applied between the first electrode and the second electrode.
