Embodiment 1

[0071] In Embodiment 1, the received signal of the AMR sensor is the magnetic field angle signal of Bx and By, and the signal curve is obtained as Figure 6 as shown, Figure 6 The fitting function of three straight lines-the relationship between the magnetic field angle y and the moving distance x is listed in ; in the existing implementation, the received signal of the HALL sensor is Bz perpendicular to the XY plane (such as figure 1 Shown) the magnetic field strength, the signal curve is obtained as Figure 5 shown. Figure 5 The fitting function of three straight lines - the relationship between the magnetic field strength y and the moving distance x is listed in . R2 in the two figures represents the degree of linearity of the straight line, the closer to 1, the better the linearity.

[0072] Although from the curve itself, the linearity is very good, but after accurate calculation, the linearity and cross influence of the two can be obtained as shown in Table 1 below....

Abstract

The invention discloses a camera stabilization control system and method, belonging to the technical field of camera control. The camera stabilization control system includes a controller, a first AMR sensor, a second AMR sensor, a first group of magnetic mechanisms, a second group of magnetic mechanisms, at least A first coil and at least one second coil; the first group of magnetic mechanisms includes at least one first magnetic mechanism, and each first magnetic mechanism is equipped with a first coil; the second group of magnetic mechanisms includes at least one second magnetic mechanism, each of the first magnetic mechanisms The second magnetic mechanism is equipped with a second coil; the first set of magnetic mechanisms is set at the first position to generate magnetic field signals; the second set of magnetic mechanisms is set at the second position to generate magnetic field signals; the controller is respectively connected to the AMR sensor and The coil adjusts the current flowing through the corresponding coil according to the magnetic field signal induced by the AMR sensor, thereby controlling the movement of the magnetic mechanism. The camera stabilization control system and method proposed by the invention can adjust the movement of the lens in the horizontal direction and precisely control the position of the lens.

Description

technical field [0001] The invention belongs to the technical field of camera control, and relates to a camera control system, in particular to a camera stabilization control system. Background technique [0002] Optical Image Stabilization (OIS-Optical Image Stabilizer) is an effective solution in camera stabilization system to solve the image quality problem, with the rapid development of consumer electronics, consumers demand higher resolution optical zoom cameras , packed into smaller, lighter DSCs and handsets, blurring due to hand shake will become more noticeable, and stabilization systems will become standard features. [0003] How to solve hand shake has become an important indicator for evaluating camera stabilization systems. Blur from hand shake can be reduced by stabilizing the camera. A microcontroller sends a hand-shake signal to a small linear motor that moves the image sensor, compensating for the camera's motion. [0004] In order for the OIS system to w...
