Embodiment Construction

[0033] There are many ways to achieve image stabilization in the prior art: Method 1: Use a large lens, the luminous flux of the Dajing head is relatively large, and the exposure time is short, which can effectively prevent shaking, but the disadvantage is that the size of the optical structure will become larger. Method 2: Use digital anti-shake technology and use software processing methods to process the captured image. Although it is relatively easy to implement, it will reduce the pixels of the captured image, so it is only suitable for low-frequency vibration and is suitable for shooting videos. Method 3: Electronic image stabilization, using a gyroscope to detect camera motion and compensate for motion in real time to improve pixel and image quality. This method provides motion compensation by cropping the image, and the compensation accuracy is low.

[0034] In view of the shortcomings of the above anti-shake methods, the present application provides an optical anti-sha...

Abstract

The invention discloses an optical anti-shake control system and method and electronic equipment, and the system comprises: a sensor input module, which is used for providing a sensor interface; a control module, which is connected with the sensor input module and is used for acquiring sensor data through the sensor interface and outputting a control signal according to the sensor data; and a motor driving module, which is connected with the control module and is used for switching to a working mode corresponding to the type of the motor to be driven according to the control signal and outputting corresponding driving current so as to realize driving of different types of motors. According to the optical anti-shake control system, a sensor interface can be provided through the sensor input module; and through the motor driving module, the working mode corresponding to the type of the motor to be driven can be switched according to the control signal, and the corresponding driving current is output to realize driving of different types of motors, so that the effect of driving the corresponding motor can be achieved without replacing a chip, and the application is more convenient.

Description

technical field [0001] The present application relates to the field of optical anti-shake, in particular to an optical anti-shake control system, method and electronic equipment. Background technique [0002] When using the camera to shoot, the camera will shake due to factors such as hand-holding and bumps. The camera uses the sensor to expose and image, and the sensor and the lens are fixedly installed on the fixed platform. Since the sensor image exposure takes a certain amount of time, if the camera shakes during the exposure, it will cause blurred shots. Anti-shake is especially important when shooting night scenes and telephoto shooting at a distance, because the exposure time will be longer in night shooting mode, and the same shaking image will be more blurred in telephoto shooting. [0003] Therefore, the camera needs to use anti-shake technology to prevent image blur caused by shooting shake. Contents of the invention [0004] In view of this, the present appl...
