Disclosed are an electronic device and a method of controlling the same. An electronic device includes: a camera; a sensor module; and a processor, wherein the processor is configured to determine at least one of a movement of the electronic device and a movement of an object in images acquired by the camera, determine, based on the movement of the electronic device or the movement of the object, an output period for light outputted by the sensor module, and determine depth information of the images based on reflected light corresponding to the outputted light received by the camera.

A driver assistance apparatus includes a camera provided in a vehicle and configured to acquire an image; and a processor configured to process the image. The camera includes an image sensor; and a variable lens that includes a liquid crystal layer and configured to alter light that is introduced into the image sensor based on an arrangement of liquid crystal molecules included in the liquid crystal layer. The arrangement of the liquid crystal molecules in the liquid crystal layer is dependent on an applied voltage.

Imaging can be performed well even when an imaging device is disposed at a position facing a peripheral portion of a substrate. A substrate processing apparatus 16 which performs a processing of removing a film on a peripheral portion of a substrate W includes a rotating/holding unit 210 configured to hold and rotate the substrate; a first processing liquid supply unit 250A configured to supply a first processing liquid for removing the film onto the peripheral portion of the substrate while the substrate is being rotated in a first rotational direction R.sub.1 by the rotating/holding unit; and an imaging unit 270 provided at a position in front of an arrival region 902 of the first processing liquid on the substrate with respect to the first rotational direction R.sub.1, and configured to image the peripheral portion of the substrate.

A focus control device is adapted to adjust a camera lens. The device comprises a rotational input device (1), a variable gear ratio means (10) and a rotational output means so coupled to communicate a first rotational movement applied to said rotational input device to said variable gear ratio means (10) and to communicate a second rotational movement from said variable gear ratio means (10) to said rotational output means. The variable gear ratio means provides a variable adjustment of the angular velocity of said second rotational movement relative to the angular velocity of said first rotational movement.

The imaging device includes a multiple-property lens that includes a first area having a first property and a second area having a second property different from the first property, an image sensor in which a first light receiving element 25A having a first microlens and a second light receiving element 25B having a second microlens having a different image forming magnification from the first microlens are two-dimensionally arranged, and a crosstalk removal processing unit that removes a crosstalk component from each of a first crosstalk image acquired from the first light receiving element 25A of the image sensor and a second crosstalk image acquired from the second light receiving element to generate a first image and a second image respectively having the first property and the second property of the multiple-property lens.

There is provided a lens barrel that can easily and reliably prevent an erroneous operation at the time of switching of a manual focus mode.

A lens barrel body houses an imaging optical system including a focus lens. A focus operation ring rotates integrally with a first connection ring about an optical axis of the imaging optical system. A second connection ring is movable between an engagement position at which the second connection ring is engaged with the first connection ring and a cam ring and a disengagement position at which the second connection ring is not engaged with both of the first connection ring and the cam ring. A switching-operation ring is movable between a rotation-restriction position at which the switching-operation ring moves the second connection ring to the engagement position and a rotation-allowable position at which the switching-operation ring moves the second connection ring to the disengagement position.
