SOLID-STATE IMAGING DEVICE AND IMAGING APPARATUS
First Claim
1. A solid-state imaging device comprising:
- a first detecting portion that detects each component by dividing a first wavelength region of image information into a plurality of wavelength regions;
a second detecting portion that detects components in the first wavelength region with higher sensitivity than the components in the first wavelength region detected by the first detecting portion; and
a signal processing unit including a high sensitization signal processing portion that acquires a signal indicating a measured amount on the basis of a unit signal corresponding to each wavelength detected in the first detecting portion and that executes a sensitivity correction operation on the unit signal corresponding to each wavelength detected in the first detecting portion by using the signal indicating the measured amount and a signal of the component in the first wavelength region, which has high sensitivity and is detected in the second detecting portion,wherein the high sensitization signal processing portion executes the sensitivity correction operation using high-sensitivity information detected in the second detecting portion and performs processing for suppressing incorrect color information while executing demosaic processing for generating information, in which wavelength components or sensitivity is uniform, from mosaic shaped information, in which wavelength components or sensitivity varies, for the position of each of all of the detecting portions.
