Dual-Camera Video Shooting Preview With Animated Transitions

The patent applies dynamics by introducing animated transition effects that transform the static, rigid picture switching into a dynamic, fluid visual experience. During mode switching, the system uses scaling animations, fading transitions, and morphing effects that continuously transform one picture view into another, eliminating the abrupt frame freezing while maintaining fast switching capability.

The patent introduces intermediary visual elements such as transition animations and intermediate frame sequences that mediate between the direct picture switching and the final displayed result. These intermediaries smooth out the abrupt transitions by providing gradual visual transformations, acting as a buffer between the fast switching mechanism and the display output.

The patent employs periodic action by using pre-rendered animation sequences and cached transition frames that are prepared in advance and replayed during switching. Instead of generating animations in real-time, the system uses periodic, pre-computed visual transformations that can be quickly applied, reducing the actual processing time during mode switching while maintaining visual fluency.

The patent applies preliminary action by pre-rendering and caching animation sequences, transition frames, and intermediate visual states before they are needed. This allows the system to have animation resources ready in advance, so when mode switching occurs, the pre-prepared visual transformations can be applied immediately without adding significant processing delay.
