A projector controlling method includes acquiring first imaging information obtained by capturing a first image projected from a projector at a first timing, acquiring second imaging information obtained by capturing a second image projected from the projector at a second timing, evaluating whether or not a change in the posture of the projector satisfies a certain criterion based on the first imaging information and the second imaging information, and outputting information based on the result of the evaluating.

An image pickup apparatus includes a tilt driving unit configured to change a tilt so as to change an angle between an image pickup plane of an image sensor and a principal plane of an image pickup optical system, a focus driving unit configured to drive a focus lens, and at least one processor that functions as an area setting unit configured to set a plurality of areas in a captured image, a defocus information detection unit configured to detect defocus information for each of the plurality of areas, and a control unit configured to select one control mode from a plurality of control modes based on the defocus information on each of the plurality of areas, the plurality of control modes being used for performing focusing control using at least one of the tilt driving unit and the focus driving unit.

An information processing device that reconstructs an original image including an interference fringe image of an object to be observed includes at least one processor. The processor acquires the original image, generates a reconstructed image while changing a reconstruction position from an initial position based on the original image, calculates sharpness of the reconstructed image each time the reconstructed image is generated and detects an in-focus position where the calculated sharpness is maximized, records the in-focus position, decides the initial position in a next reconstruction processing based on the in-focus position, and repeats the original image acquisition every one imaging cycle.

An information processing device that reconstructs an original image including an interference fringe image of at least one object to be observed is provided. The information processing device includes at least one processor that is configured to: acquire local area information representing a local area including the interference fringe image in the original image; generate a reconstructed image while changing a reconstruction position in the local area; calculate sharpness of the reconstructed image each time the reconstructed image is generated and detect an in-focus position where the sharpness is maximized; and output the reconstructed image at the in-focus position as an optimal reconstructed image.

A camera module includes a lens holder having a hollow region; a first lens unit disposed in the hollow region and including at least one lens; a second lens unit disposed above the lens holder; a circuit board disposed under the lens holder; an adhesion unit disposed between a lower surface of the lens holder and an upper surface of the circuit board and configured to couple the lens holder and the circuit board to each other. The adhesion unit includes an opening and a portion of an internal space formed by a coupling of the circuit board and the lens holder is to be open to an outside through the opening of the adhesion.

An illustrative example camera device includes a substrate and a sensor supported on the substrate. The sensor is configured to gather image information. A lens is situated near the sensor and an electroactive polymer selectively causes relative movement between the sensor and the lens.

Various embodiments include a camera with a voice coil motor (VCM) actuator assembly to provide autofocus (AF) and/or optical image stabilization (OIS) movement. The VCM actuator assembly is configured to move an image sensor of the camera in three dimensions (e.g. X, Y, and Z) to provide the AF and/or OIS movements. The VCM actuator assembly is asymmetrical and includes an at least partially open side that allows an optical assembly of the camera to pass through the open side of the VCM actuator. In some embodiments, the optical assembly is part of a folded optics arrangement of the camera that includes one or more prisms/and or lenses.
