Abstract: The present application discloses a mobile terminal with a built-in anamorphic lens, the mobile terminal is provided with a widescreen anamorphic lens which comprises a cylindrical lens group and a spherical lens group, the cylindrical lens group at least comprises a group of cylindrical negative optical power lenses and a group of cylindrical positive optical power lenses. A widescreen anamorphic lens is arranged in the mobile terminal. The optical characteristics of the cylindrical lens in the widescreen anamorphic lens are utilized to “compress” the incident light entering horizontally while keeping the incident light entering vertically unchanged, so the widescreen anamorphic lens may compress a widescreen image into a standard image area. After the compressed picture taken by the widescreen anamorphic lens is deformed and corrected by the image correction module, widescreen images and videos may be obtained, meeting the needs of users for widescreen shooting by the mobile terminal.

Abstract: A stabilizer folding structure and a handheld stabilizer. a stabilizer folding structure for rotationally connecting the motor base and the rocker arm such that the motor base and the rocker arm have an unfolded first state and a stored second state during relative rotation, comprising: an elastic member, applying An elastic force for abutting the motor base and the rocker arm; and a snap structure at a position where the motor base abuts the rocker arm, in the first state and the second state, The snap structure is engaged to restrict relative rotation of the motor base and the rocker arm. In other states, the snap structure is disengaged such that the motor base and the rocker arm are relatively rotatable. The folding structure of aspects of the invention facilitates the folding and storage of the stabilizer, and is convenient for the user to use.

Abstract: An anamorphic lens includes a cylindrical lens group arranged in a direction from an object side to an image side. The cylindrical lens group includes an anamorphic group and together form an imaging group. The anamorphic group includes a first lens, a second lens, and a third lens arranged in a direction of an object side to an image side. The second lens and the third lens may be joined together and the first lens may be a negative optical power biconcave cylindrical lens. Through the optical characteristics of the cylindrical lens in the anamorphic group, the entering horizontal light is compressed while the vertical light path maintains unchanged. The imaging group comprehensively corrects the light so that the horizontal field of view angle is increased by about 33% to achieve a magnification by 1.33 times for an anamorphic shooting.

Abstract: A holding mechanism comprising a holding base, having two oppositely arranged holding grippers with at least one of the two holding grippers being movable. A first resilient biasing member, disposed between the holding base and the movable holding gripper, exerts an elastic biasing force on the movable holding gripper to cause the movable holding gripper to have a tendency to return to its initial position. The holding mechanism includes a locking structure and an unlocking component respectively provided on the holding base. The movable holding gripper moves to a trigger position away from the other holding gripper, and the locking structure locks the movable holding gripper when reaching the trigger position to block the movable holding gripper from returning to its initial position. The unlocking component unlocks the locking structure to remove the blockage of the locking structure to the movable holding gripper.

The tripod button mechanism includes a supporting structure abutting against the button when the joint joints with the limitation structure, and an extension line between the supporting position of the support structure and the joint intersects with an extension line of the supporting leg extending towards one end where the angle position locking structure is located.

Abstract: An intelligent ball head and a self-photographing method by using the same, the method comprises determining a position of the infrared emitter carried by a user; rotating the ball head to face the infrared emitter; carrying out face recognition in a view screen with the infrared emitter as a center; measuring a first distance from a human face recognized to the intelligent ball head; comparing the first distance with a second distance from the infrared emitter to the intelligent ball head so as to calculate out a distance difference; determining that the face belongs to the user when an absolute value of the distance difference is detected to be smaller than a predetermined value; controlling the photographing apparatus to focus on the human face for shooting. When a plurality of faces appear in one viewing frame, the faces may be distinguished from each other accurately and therefore achieving high-quality self-photographing.
