A lens barrel includes a first drive mechanism which rotates a cam ring to move a cam-driven lens frame, holding a lens group, in accordance with a cam groove; a second drive mechanism which screw-engages a nut with a feed screw, biases a nut-driven lens frame to abut the nut, and moves the nut-driven lens frame. The cam-driven lens frame is positioned adjacent to the nut-driven lens frame on a reverse side to the biasing direction, and driving ranges of these lens frames partially overlap each other. The first drive mechanism includes a cam-driven member, separate from the cam-driven lens frame, which is linearly guided and provided with a cam follower which engages with the cam groove of the cam ring; and a biasing member which biases the cam-driven lens frame to abut against the cam-drive member, so that the cam-driven lens frame moves with the cam-driven member.

A camera assembly and an electronic device are provided. The camera assembly includes a housing having a first sliding groove; a camera component provided inside the housing and slidable along the first sliding groove, wherein the camera component is configured to switch between a first state and a second state by the guide of the PUSH-PUSH component when receiving a press operation; and a press-type PUSH-PUSH component provided inside the housing, wherein both ends of the PUSH-PUSH component are connected to the housing and the camera component, respectively.

The present disclosure generally relates to user interfaces. In some examples, the electronic device transitions between user interfaces for capturing photos based on data received from a first camera and a second camera. In some examples, the electronic device provides enhanced zooming capabilities that result in visual pleasing results for a displayed digital viewfinder and for captured videos. In some examples, the electronic device provides user interfaces for transitioning a digital viewfinder between a first camera with an applied digital zoom to a second camera with no digital zoom. In some examples, the electronic device prepares to capture media at various magnification levels. In some examples, the electronic device enhanced capabilities for navigating through a plurality of values.

The present invention provides a method for measuring a depth of field of an image, including: (a) picking up a first image having a first resolution at a first position; (b) driving the optical lens to move to a second position in a direction along a non-optical axis, and picking up a second image having a second resolution at the second position; and (c) synthesizing the first image and the second image, so as to obtain a third image having a third resolution, where the third resolution is greater than the first resolution and the second resolution. In addition, the present invention also provides an image pickup device and an electronic device using the method.

A camera module is provided, including a holder, a base, a bottom, an image sensor, and a first biasing element. The holder holds an optical lens and is disposed on the base. The bottom supports the image sensor and connects to the base via the first biasing element. The bottom and the image sensor can be moved with respect to the base by the first biasing element.

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 and a second light receiving element 25B having a different opening size of a light receiving section from the first light receiving element 25A 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.

An embodiment includes: a housing including an upper surface, a lower surface, an inner surface, and an outer surface located at the side opposite to the inner surface; a bobbin accommodated in the housing; a first coil disposed at an outer surface of the bobbin; a first magnet disposed at the outer surface of the housing; a second magnet disposed in the housing so as to be spaced apart from the first magnet; and a first position sensor disposed at the outer surface of the bobbin, wherein a first part of the housing is positioned between the second magnet and the inner surface of the housing.

A camera module for both normal photography and infrared photography comprises: an optical filter unit for selectively transmitting either infrared rays or visible light; an angle-of-view changing unit for narrowing the angle of view by refracting the infrared rays when the infrared rays pass through the optical filter unit, and transmitting the visible light without changing the angle of view when the visible light passes through the optical filter unit; and an image sensor for generating a normal image when the visible light is incident thereto and generating an infrared image when the infrared rays are incident thereto.

An image reading apparatus includes a placement board, a camera that captures an image of a subject placed on the placement board, a first holding member to which the camera is fixed, a second holding member that is fixed to the placement board, and a fixing portion that fixes the first holding member to the second holding member, wherein a sliding surface along a spherical surface is formed on one of the first holding member and the second holding member, three contact points disposed at three different positions respectively are formed on the other one of the first holding member and the second holding member, the first holding member is rotatably supported about three axes by the second holding member as a result of the three contact points coming into contact with the sliding surface, and the camera is disposed inside the spherical surface.

An embodiment includes: a housing including an upper surface, a lower surface, an inner surface, and an outer surface located at the side opposite to the inner surface; a bobbin accommodated in the housing; a first coil disposed at an outer surface of the bobbin; a first magnet disposed at the outer surface of the housing; a second magnet disposed in the housing so as to be spaced apart from the first magnet; and a first position sensor disposed at the outer surface of the bobbin, wherein a first part of the housing is positioned between the second magnet and the inner surface of the housing.
