Description

Anti-shake cradle head

Technical Field

The utility model relates to a cloud platform field, concretely relates to anti-shake cloud platform.

Background

In recent years, mobile devices having a fixed-focus wide-angle (viewing angle exceeding 80 degrees) shooting function have become popular, and the application range thereof has been expanding, including aerial photography, motion cameras, and automobile data recorders. When taking pictures and taking films, it is likely to be blurred or shaken by external vibration, which affects the quality of the pictures and films. This problem is exacerbated when the vibrations are relatively intense, or in low light conditions.

In order to solve the above problems, a lot of existing anti-shake technologies have appeared on the market. The mainstream prior art achieves the effect of improving the image quality by reading the vibration sensors (such as gyroscope and acceleration sensor), calculating the vibration waveform and the required compensation angle, and compensating the image blur and shake caused by vibration by electronic, optical, or mechanical methods.

The prior art mainly includes an Electronic Image Stabilizer (EIS) and an Optical Image Stabilizer (OIS) according to a vibration compensation method.

EIS is an electronic method to achieve the anti-shake effect. During shooting, the EIS adjusts the position of each frame of image according to the calculated vibration waveform to counteract the image shake caused by vibration. The main advantage of EIS is low cost, no extra weight and volume, since EIS does not require additional actuators. The main disadvantage of EIS is that it cannot compensate for image shaking in each frame, since EIS counteracts image shaking due to vibration by adjusting the position of each image. Therefore, the image shot after the EIS is turned on is easy to blur due to image shaking. Another disadvantage of EIS is that the resolution of the image sensor is sacrificed. When the EIS is turned on, the image sensor or the image processor needs to cut out an appropriate image according to the calculated vibration waveform as a final image. During cropping, the resolution will decrease and the final image will have a lower resolution than the image, the sensor maximum. Therefore, EIS sacrifices the maximum resolution of the image sensor and reduces the image quality. The main disadvantage of OIS over EIS is the need for additional actuators, and therefore higher additional cost, more additional space, and higher additional weight.

The OIS is an Optical and mechanical method, in which an actuator is used to move an Optical component (which may be one, one or all lenses in a camera) to achieve a relative motion between the Optical component and an Image sensor, and the Optical Path (Optical Path) and the position of an imaging Circle (Image Circle) are changed to counteract the Image shake caused by vibration. Since the OIS is continuously compensated for taking each frame of image, it can counteract the jitter during exposure of each frame of image, and achieve better image quality than EIS. The main disadvantage of OIS is the sacrifice of partial optical resolution of the lens. During OIS, the position of the imaging circle on the image sensor changes constantly. In order to avoid the image circle from exceeding the image sensor during OIS, the image circle must be enlarged for OIS, but this wastes the resolution that the lens should have. On the other hand, in the OIS process, when the position of the imaging circle is more off-set, the edge of the imaging circle is closer to the image sensor. Since most lenses have more severe blur and distortion at the edges than at the center, the image resolution and anti-shake effect of the conventional OIS are inferior to GS, which is more obvious in the wide-angle camera module.
