Abstract: An optical camera lens includes a first camera lens component including at least one first lens and a second camera lens component including a second lens barrel and at least one second lens mounted in the second lens barrel. The first and second lenses together constitute an imageable optical system. At least one of the two camera lens components has a smooth region located on an end surface of the camera lens component, and a connecting medium for fixing the first and second camera lens components together. A corresponding assembly method of the optical camera lens and a corresponding camera module and an assembly method thereof are also provided. The optical camera lens can improve a pre-positioning accuracy by improving a height measurement accuracy, and can use a distance measuring point as a feature point of image recognition so as to perform pre-positioning and active calibration.

Abstract: A method for assembling an optical lens includes preparing a first lenses part including a first lens and a second lenses part including a second lens, capturing the first lenses part, and adjusting a posture of the first lenses part according to a distance measurement result, so that an included angle between a first end surface of the first lenses part and a second end surface of the second lenses part is less than a threshold of inclination angle. The method also includes adjusting the first lenses part at degree of freedom of linear movement to complete pre-positioning, performing an active alignment of a position of the first lenses part at the degree of freedom of linear movement according to an actual imaging result, and fixing the first and second lenses parts together, so that their relative positions are maintained at the relative positions determined by the active alignment.

Abstract: An assembly device for an optical assembly comprises: a grasping mechanism (310) configured to grasp a first sub-lens to be assembled, and to move the grasped first sub-lens in multiple degrees of freedom; a first fixing mechanism (320) configured to fix a second sub-lens to be assembled, wherein the grasping mechanism (310) is movable relative to the first fixing mechanism (320), so that the first sub-lens and the second sub-lens form an optical system capable of imaging; a second fixing mechanism (330) configured to fix a photosensitive assembly; a data acquiring assembly (340) configured to be electrically connected to the photosensitive assembly fixed by the fixing mechanism (330) and acquire image data output by the photosensitive assembly; and a material connecting assembly (210) configured to fix the first and second sub-lenses together.

Abstract: A video playback method and apparatus are provided. The video playback method includes receiving a first video stream, playing the first video stream on a first playing path, and outputting content of the first playing path; acquiring tag information of the first video stream and, based on the tag information, playing a second video stream on a second playing path; and stopping output of the content of the first playing path and outputting content of the second playing path based on the tag information. Through the video playback method of the present application, advertisements can be dynamically switched effectively, thereby improving the viewing experience of the user.
