Image anti-shake method, electronic equipment and storage medium

Abstract

The invention discloses an image anti-shake method, electronic equipment and a storage medium. The electronic equipment has an optical anti-shake mode and an electronic anti-shake mode, and the methodcomprises the steps: employing the optical anti-shake mode to control a shooting module for shooting, and obtaining the measurement offset of the center of a lens of the shooting module and the current working temperature of the shooting module through measurement; correcting the measurement offset based on a preset offset correction strategy and the current working temperature to obtain a real offset of the center of the lens; and performing electronic anti-shake processing on the shot image by adopting an electronic anti-shake mode based on the real offset of the center of the lens. Therefore, when the anti-shake mode of EIS + OIS is in use, the real offset is obtained by correcting the measurement offset of the center position of the lens, and the electronic anti-shake effect can be improved by performing EIS anti-shake processing on the shot image based on the real offset, so the electronic equipment has the advantages of eliminating motion blur by OIS anti-shake and enlarging thecompensation range by EIS anti-shake.

Description

technical field [0001] The present application relates to image processing technology, and in particular to an image stabilization method, electronic equipment and a storage medium. Background technique [0002] Optical image stabilization (Optical Image Stabilization, OIS) is a technology often used in mobile terminal image stabilization at present. It detects the real-time motion posture of the mobile terminal and actively moves the lens in the horizontal and vertical directions to compensate for the mobile terminal's surroundings. The rotation of the X-axis (pitch) and the rotation around the Y-axis (yaw) ensures the stable effect of the imaging image of the image sensor. [0003] When a user uses a mobile terminal to take pictures, the mobile terminal will move frequently. Simply using OIS can no longer meet the anti-shake requirements of the mobile terminal. Therefore, OIS combined with Electronic Image Stabilization (EIS) for anti-shake has emerged, referred to as EIS+...

Problems solved by technology

[0003] When a user uses a mobile terminal to take pictures, the mobile terminal will move frequently. Simply using OIS can no longer meet the anti-shake requirements of the mobile terminal. Therefore, OIS combined with Electronic Image Stabilization (EIS) for anti-shake has emerged, referred to as EIS+OIS. anti-shake

[0004] In the existing EIS+OIS solution, the lens will move due to the OIS mechanism, which will lead to the movement of the lens. When using EIS anti-shake, it is necessary to know the actual position of the lens accurately, but there is an error in the actual position of the lens measured, which will lead to EIS. Anti-shake effect becomes worse
