11477382 · 2022-10-18 · ·

A method operable within an image capture device for stabilizing a sequence of images captured by the image capture device is disclosed. The method comprises, using lens based sensors indicating image capture device movement during image acquisition, performing optical image stabilization (OIS) during acquisition of each image of the sequence of images to provide a sequence of OIS corrected images. Movement of the device for each frame during which each OIS corrected image is captured is determined using inertial measurement sensors. At least an estimate of OIS control performed during acquisition of an image is obtained. The estimate is removed from the intra-frame movement determined for the frame during which the OIS corrected image was captured to provide a residual measurement of movement for the frame. Electronic image stabilization (EIS) of each OIS corrected image based on the residual measurement is performed to provide a stabilized sequence of images.

Image transformation in hybrid sourcing architecture

Image transformation for use in a hybrid distribution architecture with improved performance characteristics is provided herein. The hybrid distribution architecture provides content to clients via a dual source system using a central cloud service and a Content Distribution Network, which uses the cloud service as its source. A client that requests a new rendition of an image provided by a chosen source of the hybrid distribution architecture will have that request handled by the source, and the source may maintain that rendition for future provision. By allowing the client to choose the source and letting that source handle the request, rather than requiring a central service hand the request, the amount of data needed to be transmitted is reduced and the speed of provision of content, modified or not, is improved for the client.
