Abstract: A liquid crystal panel has a hole allowing light to pass through or to be shielded, and suppresses an influence on the light passing through the hole. A liquid crystal panel includes: a first substrate having a flat plate shape; a second substrate arranged to face the first substrate; a light shielding film spreading along an inner surface of the second substrate and having the hole formed therein; a plurality of spacers arranged on an outer side of a region between the substrates, the region corresponding to the hole; and a liquid crystal sandwiched between the first substrate and the second substrate. The second substrate is held such that a distance from the first substrate becomes larger as coming closer to the hole, and the portion corresponding to the hole has a shape protruding in a direction extending from the first substrate to the second substrate.

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.
