NOISE PROCESSING IN IMAGE FRAMES FOR DIGITAL VIDEO

Abstract:

Aspects relate to noise processing of image frames for video. An example device is configured to perform operations including receiving a sequence of image frames for a digital video, determining an image quality metric of a first image frame from the sequence of image frames, and determining a number of image frames from the sequence of image frames to be blended based on the image quality metric (with the number of image frames including the first image frame). The operations also include blending the number of image frames to generate a blended image frame of the digital video. The image quality metric may include a light intensity metric (such as a luminance metric measured during an autoexposure operation) or a sharpness metric (such as a focus metric measured during an autofocus operation).
