Abstract: An imaging apparatus performs focusing calculation for calculating a focusing position of a focus lens based on a signal for calculation read out from an imaging element. A focus adjustment unit includes a setting unit and a focusing calculation unit. A detection unit detects, from a signal for image generation, a rectangular region including a target portion of a target subject of the focusing calculation and a peripheral portion of the target portion. The setting unit is configured to set a high contribution degree region where a degree of contribution to the focusing calculation is higher than other regions in the rectangular region, based on a combination of the target subject and the target portion. The focusing calculation unit performs, in a case where the high contribution degree region is set, the focusing calculation in accordance with the setting.
