Title:
IMAGING APPARATUS, IMAGE PROCESSING APPARATUS, CONTROL METHOD OF IMAGING APPARATUS, AND PROGRAM
Document Type and Number:
Japanese Patent JP2020028045
Kind Code:
A
Abstract:
To provide a technique for suppressing a decrease in image quality due to a transmittance distribution of an optical member using an EC element in an imaging apparatus.SOLUTION: The imaging apparatus including an imaging element, using an electrochromic element, that captures a subject image formed by light passing through an optical member capable of electrically controlling light transmittance, includes: distribution acquisition means for acquiring distribution characteristics of transmittance of the electrochromic element on the basis of a current value flowing through the electrochromic element; and image processing means for correcting an image signal picked up by the imaging element according to the distribution characteristics.SELECTED DRAWING: Figure 4
