A camera for realizing cooperative anti-shake by using optical anti-shake and electronic anti-shake. On the basis of the present application, in any refresh cycle of an image sensor, it is possible that only part of a real-time spatial angle of the camera is offset by optical anti-shake within an optical anti-shake capability range of the camera, so as to facilitate a reduction in the risk of optical anti-shake failure. In addition, on the basis of the part of the spatial angle that is offset by optical anti-shake, it is also possible to reduce the risk of image definition being excessively low due to an excessively large spatial angle. Therefore, at a refresh moment when an imaging cycle ends, image processing is performed on an image, the definition of which has been improved by optical anti-shake, by means of electronic anti-shake, such that the influence of the remaining part of the real-time spatial angle of the camera on image quality can be compensated for. Thus, two modes are combined in such a way that electronic anti-shake compensates for optical anti-shake, thereby facilitating a reduction in the risk of anti-shake failure.

Disclosed are a decoding method based on an adaptive intra-frame refreshing mechanism, an encoding method based on an adaptive intra-frame refresh mechanism, and a related device, which belong to the field of video encoding and decoding. In the embodiments of the present application, an adaptive intra-frame video refreshing extension number and virtual boundary location mark information are newly added to extended data in a code stream of the current frame. In this way, since virtual boundary location mark information can indicate the location of a virtual boundary, and the virtual boundary is at least used for distinguishing between a refreshed area and a non-refreshed area in the current frame, when dividing the refreshed area of the current frame, an encoding terminal can arbitrarily set the virtual boundary on the basis of actual demands, and indicate the location of the virtual boundary by means of the virtual boundary location mark information, thereby effectively improving the flexibility of area division.
