A camera device with image compensation and autofocus function, comprising a first carrying member, a second carrying member, a camera module, a first optical compensation component, a third carrying member, and an autofocus component. The second carrying member is movably assembled to the first carrying member. The first optical compensation component comprises a first force interaction member disposed at the first carrying member and a second force interaction member disposed at the second carrying member, which generate force interaction, allowing the second carrying member to move in the direction of a first axis or/and a second axis intersecting with an optical axis of the optical lens for optical compensation for the optical lens. The third carrying member bears the optical lens and is movably disposed on the second carrying member. The third carrying member could move along an optical axis of the optical lens.

A method, system, and computer program product for determining a core-to-ferrule offset of a ferrule for a fiber optic connector. A reference ferrule is physically aligned with a core imager by positioning the reference ferrule so that edges of the reference ferrule in a plurality of profile images are aligned with fiducial markers in the images. The reference ferrule is incrementally rotated about its longitudinal center access, a core image captured at each rotational angle, and a reference core-to-ferrule offset determined based on the core images. A test ferrule is physically aligned with the core imager by positioning the test ferrule so that edges of the test ferule are aligned with the edges of the reference ferrule in a plurality of profile images. The core-to-ferrule offset of the test ferrule is then determined based on an offset between the test and reference cores in a composite core image.

An autofocus (AF) frame integration unit generates at least two groups, each group including at least one focus detection area based on a comparison between a plurality of focus detection results, the plurality of focus detection results to be obtained corresponding to a specific time. A movement determination unit determines whether an object corresponding to a first group and a second group is moving, based on a focus detection result corresponding to the first group, generated based on a focus detection result corresponding to a first time, and a focus detection result corresponding to the second group, generated based on a focus detection result corresponding to a second time later than the first time.

A collimator includes a front lens sleeve, a clamping groove disposed on the front lens sleeve, a linking sleeve fastened on the clamping groove, a snapping groove disposed on the linking sleeve distal the front lens sleeve, a connection sleeve slidably connected to the snapping groove, a constraint sleeve disposed on the snapping groove, and a limit groove disposed on an inner surface of the constraint sleeve. The components cooperate with each other. The test chart is tilted relative to the optical axis of the lens and makes the test chart distributed at different distances along the axis. When using the camera to shoot the collimator, the clarity of different components reflects the relative focus position of the camera so as to detect the vehicle mounted camera.

A display control apparatus includes an acquisition unit configured to acquire information about an in-focus position on a live view image, and a display control unit configured to perform control to display an item indicating the in-focus position on the live view image, based on the information acquired by the acquisition unit. The display control unit performs control to display a first item at a first in-focus position at which focus is continuously achieved, in a display form having higher visibility than in a display form of a second item to be displayed at a second in-focus position at which focus is not achieved at least last time, the first in-focus position and the second in-focus position being positions at which focus is currently achieved.

A variable focal length optical assembly may include a deformable entry lens element, a deformable first reflective element and a deformable second reflective element. Using a controller coupled to the deformable elements, an external force such as a mechanical, electrical, electromechanical, or electromagnetic force is applied to the deformable elements to provide any number of different focal lengths. Since the deformation of the deformable elements, and consequently the changes in focal length, occur much faster than the playback frame rate, a number of sub-frames, each containing an image obtained at a different focal length, are associated with each playback frame. The availability of multiple images in the form of sub-frames permits the selection of an optimal image for inclusion in the final playback frame sequence. The availability of multiple images in the form of sub-frames at different focal lengths also permits the seamless incorporation of zoom-in and zoom-out effects.

A depth measurement apparatus including an illumination module, a beam splitter, an objective lens, an image capture module, a controller and a processor is provided. The illumination module is configured to generate an illumination beam. The beam splitter and the objective lens are disposed on an optical path of the illumination beam, and the object lens is configured to focus the illumination beam into a hole formed in an object. The image capture module is configured to capture images of the hole at different heights. The controller is coupled to the illumination module and the image capture module. The processor is coupled to the controller and the image capture module, and configured to perform focus distance evaluations on the images captured by the image capture module to obtain a height difference between two surfaces of the object. A depth measurement method is also provided.
