The lens holder includes a base plate, a number of claws extending up from the base plate and sleeving on the connecting barrel, a fixing block extending up from the base plate and defining a fixing hole, a tightening ring sleeving on the claws and having two end sections sandwiching the fixing block. The tightening ring also includes a tightening screw for threadedly passing the threaded holes to tightening the tightening ring such that the claws deforms and grasps the connecting barrel.

Abstract: A camera module includes a lens holder, a lens held by the lens holder, an image sensor, a guiding device, and a driving motor. The lens holder includes guiding rods which impose a movement track on the guiding device so as to hold the image sensor very steadily and precisely for focusing purposes, in moving towards or away from the lens.

Abstract: An image capture system comprises a lens module, a color filter frame, and a cover. The lens module has an image sensor received in the cover. The cover has a threaded hole corresponding to the image sensor. The color filter frame comprises at least one bracket and a fixing frame. The bracket including a color filter is fixed by the fixing frame corresponding to the threaded hole.

Abstract: An image display module adapted for displaying an image in an electronic device, includes a bottom cover, a sliding portion movably mounted on the bottom cover, a screen received in the bottom cover, an upper cover fastened and aligned to the bottom cover, and a sensor arranged on the upper cover. An opening is defined in the upper cover for exposing the screen and displaying images captured by the electronic device. The sliding portion can move from a first position to a second position relative to the bottom cover. When the sliding portion is at the first position, the sliding portion is away from the sensor, the opening is partially covered and a part of the screen is exposed for displaying images. When the sliding portion moves to the second position relative to the bottom cover, the sliding portion engages the sensor, and the screen is fully exposed for displaying images.

Abstract: An image sensor includes a base an image sensor chip, and a cooling element. The base includes an opening disposed in the base. The image sensor chip is connected electrically to the base and covers the opening. The cooling element is received in the opening and is connected thermally to the image sensor chip. Heat produced by the image sensor chip can be dissipated in time by the cooling elements in the image sensor. The cooling elements maintain the image sensor chip works under a temperature no more than the rated working temperature of the image sensor chip and therefore extend the life of the image sensor, and improve the image quality of the image sensor chip.

Abstract: An image capture assembly is disclosed. The image capture assembly includes a housing, a lens unit, an image detection unit, three screws, and three elastic members. The housing includes a lens-receiving portion, and three screw-receiving portions on an inner surface of the housing and surrounding the lens-receiving portion, an end surface of each screw-receiving portion defining a threaded hole. The lens unit is received in the lens-receiving portion. The image detection unit includes a substrate and an image sensor. The substrate facing the inner surface of the housing defines three through holes therein aligned with the three screw-receiving portions respectively.
