Title: IMAGING DEVICE, IMAGING SYSTEM, AND CONTROL METHOD FOR IMAGING DEVICE
Abstract:
The present invention improves the accuracy of white balance correction in an imaging device provided with a plurality of optical systems with different angles of view. A wide-angle side light detection unit detects a plurality of wide-angle side color components in each of a plurality of regions within wide-angle image data with an angle of view wider than a predetermined value. A telephoto side light detection unit detects a plurality of telephoto side color components in each of a plurality of regions within telephoto image data with an angle of view narrower than the predetermined value. A telephoto side white balance gain acquisition unit finds, as a telephoto side white balance gain, a gain for the telephoto image data on the basis of a wide-angle side integration ratio that is a ratio between the integrated values of each of the plurality of wide-angle side color components, and the plurality of telephoto side color components. A telephoto side white balance correction unit corrects the telephoto image data using the telephoto side white balance gain.
