The image-pickup apparatus includes an image acquiring part respectively photoelectrically converting first and second object images respectively formed by first and second light fluxes into first image data and second image data, the first and second light fluxes being formed by dividing a light flux from an image-pickup optical system by a pupil divider, and photoelectrically converting a third object image formed by a third light flux of the light flux from the image-pickup optical system into third image data, the third light flux being not divided by the pupil divider, and a split image generating part which generates split image data to be displayed in the third image data. The split image generating part generates the split image data based on the first image data and the second image data, and adds color information extracted from the third image data to the split image data.
