A camera module includes a positioning plate, a positioning frame, a spring member, a lens holder, and a piezoelectric actuator. The positioning frame is fixed to the positioning plate and defines a positioning through hole. The spring member is disposed on the positioning plate and in a compressed state. The lens holder is received in the positioning through hole and movably engaged with the positioning frame. The piezoelectric actuator is sandwiched between the compressed spring member and the lens holder. The piezoelectric actuator is operable to drive the lens holder to rotate about a central axis of the positioning frame, thereby move along the central axis relative to the positioning frame.

An optical touch device includes a touch panel, an infrared light pen, and an infrared camera module. The infrared light pen emits infrared light towards a surface of the touch panel. The touch panel includes a display panel and an infrared reflective element. The infrared reflective element is stacked on the display panel and faces the infrared camera module. The infrared reflective element reflects the infrared light to the camera module. The camera module captures images of the infrared light reflected by the infrared reflective element.

An image capturing device includes a housing, a camera module, polarizer, and a cover. The housing defines a through hole. The camera module is received in the housing and aligned with the through hole. The cover defines an opening. The polarizer is connected to the cover. The cover is detachably engaged with the housing. The camera module, the through hole, the polarizer, the opening aligned with each other.

A lens arrangement includes two lenses. Each lens includes an optical portion having an optical axis, a non-optical portion surrounding the optical portion, and an engagement portion extending along and inclining relative to the optical axis from the non-optical portion. The engagement portions of the lenses are engaged with each other and an included angle is defined between the engagement portions. One of the lenses includes an elastic element which can be flexibly deformed relative to the other lens.

A lens arrangement includes two lenses. Each lens includes an optical portion having an optical axis, a non-optical portion surrounding the optical portion, and an engagement portion extending along the optical axis from the non-optical portion. One of the engagement portions includes an outer wall and an inner wall parallel to the outer wall with an annular groove defined therebetween, while the other engagement portion defines a corresponding annular space for receiving the outer wall and the inner wall therein, therefore the engagement portions are interferentially engaged with each other.

A scanning unit includes a lamp-mounting body having a top surface formed with an elongate opening that is disposed between a pair of parallel first and second grooves. First and second reflective layers are attached respectively over curved groove-defining surfaces of walls defining respectively the first and second grooves. Tubular first and second lamps are mounted respectively in the first and second grooves. An intersecting line of a first plane in which a middle line of the curved groove-defining surface defining the first groove and a first central axis of the first lamp are disposed, and a second plane in which a middle line of the curved groove-defining surface defining the second groove and a second central axis of the second lamp are disposed, is located on a scanning surface, and is disposed directly above the opening.

An exemplary camera module includes a lens holder and a lens barrel. The lens holder includes a cylindrical receiving cavity defined therein and an inner smooth surface in the cylindrical receiving cavity. The lens barrel is received in the cylindrical receiving cavity. The lens barrel includes a hollow cylinder and a plurality of spaced protrusions arranged on the outer cylindrical surface of the hollow cylinder. The outer cylindrical surface is spaced from the inner smooth surface. The protrusions abut against the inner smooth surface.

An exemplary digital picture frame includes a frame body, a supporting portion, a carrying portion, an image capturing unit and light sources. The frame body includes a rear surface. The supporting portion extends from the rear surface and is configured for supporting the digital picture frame on a supporting surface. The carrying portion is arranged at the rear surface. The carrying portion includes a mount for facing the supporting surface. The mount is configured for holding a printed picture thereon. The image capturing unit is arranged at the supporting portion and is configured for capturing an image of the printed picture. The light sources are arranged at the supporting portion and are configured for illuminating the printed picture.
