Image stabilization and blending for video encoding
A patent application (Publication Number: US20240040251A1) describes a method and camera apparatus for generating blended images emulating different shutter angles and frame rates. The method involves obtaining images at a first shutter angle and frame rate, interpolating intermediate images, combining them to generate blended images, and encoding a video stream. The patent also includes stabilizing images, using deep learning-based or linear frame interpolation for generating intermediate images, and reducing power to the camera sensor between captures.
The camera apparatus comprises a camera sensor, a processor subsystem with an image signal processor and a neural network processing unit, and a computer-readable medium with instructions for developing exposures into images, interpolating intermediate images, and combining them to generate blended images. The apparatus also includes features like in-camera stabilization based on motion data from an accelerometer and gyroscope, scaling stabilized images, estimating motion, and encoding blended images into a video stream. Additionally, the camera apparatus can stream videos wirelessly, store them in removable memory, and interpolate exposures to create blended exposures emulating different shutter angles and frame rates. The patent application emphasizes the use of neural network processing units for image interpolation and stabilization, showcasing advancements in camera technology for enhanced video quality.
