US 12,604,105 B2 · Signal processing device and method, and program

Abstract

The present technology relates to a signal processing device and method, and program capable of performing appropriate white balance adjustment without blocked-up shadows occurring. A signal processing device includes: a detection unit that detects, based on a first polarization image of a plurality of polarization images with mutually different polarization directions, a specular reflection region in the polarization image, each of the polarization images being a captured image of a same subject; and a white reference acquisition unit that acquires, based on a result of detecting the specular reflection region, a white reference for balance adjustment from the specular reflection region of a second polarization image of the plurality of polarization images, the second polarization image having fewer specular reflection components than the first polarization image. The present technology can be applied in a signal processing device.
