Abstract
A focus control device, comprising an image sensor capable of generating a phase difference detection signal, a focus detection region setting circuit that sets a plurality of focus detection regions having at least some parts in common, in a region of the image sensor that receives the light flux, an AF control circuit comprising a first calculation section that calculates a first focus direction based on a phase difference detection signal from a first focus detection region, and a second calculation section that is capable of detecting a larger focus deviation amount than a focus deviation amount that can be detected by the first calculation section, and calculates a second focus direction based on a phase difference detection signal from a second focus detection region, and a controller that determines focus direction in which to perform focus adjustment based on the first focus direction and the second focus direction.
