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.

Abstract: According to one embodiment, a camera module includes an imaging device, a liquid crystal panel and a lens. The liquid crystal panel includes first to fourth areas, a liquid crystal layer, and a driver. A size of the third and fourth areas is smaller than a size of the first and second areas. A first distance to a subject is calculated based on first and second images. The first image is based on light transmitted through the first area. The second image is based on light transmitted through the second area. A second distance to the subject is calculated based on third and fourth images. The third image is based on light transmitted through the third area. The fourth image is based on light transmitted through the fourth area.
