Abstract: A camera substrate assembly, a camera apparatus, and a terminal device, where the camera substrate assembly includes a rigid support plate and a printed circuit board laminated, where at least two mounting holes for accommodating camera chips are disposed on the printed circuit board, the rigid support plate has mounting surfaces facing the mounting holes respectively and are configured to support the camera chips, strength of the rigid support plate is greater than strength of the printed circuit board, and flatness of the mounting surfaces is less than a specified threshold. The mounting holes disposed on the printed circuit board and the mounting surfaces disposed on the rigid support plate are used to support cameras. This avoids impact of warpage on camera mounting when the printed circuit board and a flexible circuit board are laminated, and improves flatness after camera mounting.

Abstract: An electronic device includes a camera assembly and an image stabilization motor. The image stabilization motor includes a base, a movable assembly, a suspension assembly, a driving assembly, and a first flexible circuit board. The movable assembly is disposed at the bottom of the base, and includes a main circuit board and an image sensor. One end of the first flexible circuit board is connected to an end surface of the main circuit board, the other end of the first flexible circuit board is connected to a board-to-board connector, and at least a portion of the first flexible circuit board is attached to a side wall of the base. A mover is configured to drive, under an action of a stator, the movable assembly to shift and roll on a plane on which an image sensor is located.

Abstract: An optical image stabilization module and an electronic device. The optical image stabilization module includes a first bracket, a second bracket, and a third bracket that are nested in sequence from inside to outside, and an optical lens module fixed on the first bracket. A first connection assembly is arranged between the first bracket and the second bracket, to enable the first bracket and the second bracket to form a rotational connection about a first rotation axis. A second connection assembly is arranged between the second bracket and the third bracket, to enable the second bracket and the third bracket to form a rotational connection about a second rotation axis. The first rotation axis, the second rotation axis, and an optical axis of the camera are perpendicular to each other.

Abstract: A camera module includes a planoconvex lens, a first reflector, a focusing lens, a prime lens, a second reflector, a chip module, and a stabilization motor that are sequentially arranged from an object side to an image side. The first reflector is configured to direct an optical axis from a first direction to a second direction. The second reflector is configured to direct the optical axis from the second direction to a third direction. In this way, the photosensitive surface of the chip module may not be limited by a size of the camera module in a direction that is perpendicular to the second direction, and a large photosensitive surface design of the photosensitive surface of the chip module can be implemented.

Abstract: A lens structure includes a lens tube; a first lens located on a first end-face of the lens tube, where the first lens includes a light converging region and an edge region located at an edge around the light converging region; a light shielding structure covering the edge region of the first lens; and at least one second lens located inside the lens tube. Based on the lens structure, the first lens is disposed on an outer side of a housing of the lens tube. Therefore, an adjustment degree is relatively high, and convenience and flexibility are relatively desirable. In addition, an optical axis of the first lens and an optical axis of the at least one second lens are aligned at a relatively high extent, thereby improving quality of the lens structure and a yield of the lens structure.
