Abstract: A depth calculating unit calculates a depth for each of a plurality of unit regions (for example, pixels) forming a depth map. A dividing unit divides an image region corresponding to a captured image into a plurality of partial regions. A noise removing unit removes, using a first parameter, noise from estimated depths calculated for a plurality of unit regions included in a first partial region. The noise removing unit removes, using a second parameter, noise from estimated depths calculated for a plurality of unit regions included in a second partial region. This prevents a problem in that an estimated depth that should originally be displayed is excluded from the depth map.
