Abstract:
1. A defective pixel correction method comprising: a first defective pixel correction step of specifying a defective pixel included in an image signal of each of color signals sent from an imaging unit, and obtaining a linear interpolation value from pixels around the defective pixel to perform a first defective pixel correction process on the defective pixel by the linear interpolation, and a second defective pixel correction step of performing an aberration correction process based on an image signal of a specific color after the first defective pixel correction process, and performing a second defective pixel correction process different from the first defective pixel correction process on the pixel subjected to the first defective pixel correction process, wherein the second defective pixel correction process is a correction process for adding a high-frequency component, generated from an image signal of a different color signal, to the pixel subjected to the first defective pixel correction process and a pixel generated in the aberration correction process using the pixel subjected to the first defective pixel correction process.
