An adjustable camera module and an assembly test method therefor. The assembly test method for the adjustable camera module comprises: measuring a static tilt amount between the optical lens sheet group and the photosensitive assembly by performing a defocus curve test on the adjustable camera module; analyzing a static adjusting electric quantity of each adjustment coil of an adjustment coil group according to the static tilt amount; and burning the static adjusting electric quantity required by each adjustment coil so as to reduce process requirements.

A system and method for guiding placement of a vehicle service external fixture relative to a vehicle undergoing service or inspection. A vehicle service system support structure having at least one camera module is positioned at an initial location within a vehicle service area, and a location of the initial location within a vehicle reference frame is established from images of optical targets secured to the vehicle. The vehicle service system support structure is subsequently repositioned relative to the vehicle to a new position located outside of an external fixture placement region, while maintaining at least one of the observed optical targets within a field of view of the camera module. The new position of the vehicle service system support structure within said vehicle reference frame is determined from target images, and a placement location within the placement region for the external fixture is identified relative to the vehicle.

An image projection apparatus includes a projection optical system configured to project an image with light emitted from a light source; a photodetector, and circuitry. The photodetector is configured to detect an amount of first light out of the light emitted from the light source and does not enter the projection optical system, and an amount of second light out of the light emitted from the light source and has passed through the projection optical system. The circuitry is configured to compare the amount of first light and the amount of second light, and control a notification device to perform a notification operation in response to reception of a comparison result that a difference in the amount of first light and the amount of second light is equal to or greater than a threshold.

A camera device calibration method according to one embodiment comprises the steps of: acquiring first data including location values of a first zoom lens and location values of a first focus lens, corresponding to the location values of the first zoom lens; setting at least two location points of the first zoom lens; acquiring at least two location values, which correspond to the location values of the first focus lens corresponding to at least two location points of the first zoom lens; acquiring second data corresponding to a value between at least two location values of the first zoom lens; and setting, in a camera including the first zoom lens and the first focus lens, at least two location values of the first zoom lens and the first focus lens when a difference value, which is acquired by comparing the first data with the second data, is within a preset threshold range.

An automatic robot control system and methods relating thereto are described. These systems include components such as a touch screen panel (“TSP”) robot controller for controlling a TSP robot, a camera robot controller for controlling a camera robot and an audio robot controller for controlling an audio robot. The TSP robot operates inside a TSP testing subsystem, the camera robot operates inside a camera testing subsystem, and the audio robot operates inside an audio testing subsystem. Inside the audio testing subsystem, an audio signals measurement system, using a bi-directional coupling, controls the operation of the audio robot controller. In this control scheme, a test application controller is designed to control the different types of subsystem robots. Methods relating to TSP, camera, and audio robots, and their controllers, taken individually or in combination, for automatic testing of device functionalities are also described.

Systems, methods and apparatus to continuously calibrate images displayed on a screen or surface by one or more projection devices during display of the images are disclosed. The systems, methods and apparatus comprise defining a plurality of fiducial markers on the screen, detecting, by a registration device, such as a camera, the plurality of fiducial markers in an image of the screen, adding a plurality of reference markers to an image displayed on the screen, detecting, by the registration device, the plurality of reference markers in the displayed image, determining a mapping between positions of the reference markers on the screen to positions of the reference markers in the displayed images, calculating an image warp based on the mapping and a layout of the images to be displayed and applying the image warp to images from an image generator to produce geometrically corrected images for display on the screen.

A lens barrel includes: a tubular cam follower; a cam barrel having a cam groove that is engaged with the cam follower; and a lens support member that supports a lens, the lens support member has a protruding portion that protrudes outward in a radial direction of the lens from an outer peripheral portion of the lens support member and that is inserted into the cam follower, and the cam follower and the lens support member are stuck to each other in a non-fastened state.

One embodiment of a camera module comprises: a lens barrel including at least one lens; a bobbin for accommodating the lens barrel; and a fixing part disposed between the lens barrel and the bobbin so as to inhibit the lens barrel from being separated from the bobbin, wherein one surface, which makes surface contact with the fixing part, of the bobbin can include a bobbin provided so as to protrude toward the lens barrel.
