Imaging device, imaging system, and method of controlling imaging device

An imaging system, comprising:

• circuitry configured to:
• detect a plurality of wide-angle-side color components in each of a first plurality of regions in wide-angle image data, wherein the wide-angle image data has a first angle of view wider than a value;
• detect a plurality of telephoto-side color components in each of a second plurality of regions in telephoto image data, wherein the telephoto image data has a second angle of view narrower than the value;
• calculate a wide-angle-side integration ratio based on a ratio of respective integration values of the plurality of wide-angle-side color components and the plurality of telephoto-side color components;
• obtain a telephoto-side white balance gain for the telephoto image data based on the wide-angle-side integration ratio;
