MULTI-FOCUS IMAGE DATA COMPRESSION

摘要

Systems and methods for converting multi-focus image data into a compressed video format. Multi-focus image data of a scene may be sampled to generate a stack of images spanning multiple focal depths. Each image focal distance is mapped to a time stamp and a video encoder is employed to generate a compressed video stream of scene information. In further embodiments, the video encoded scene information is decoded and frames from the stream selected for display based on the focal distance-time stamp mapping. In further embodiments, multi-focus video data is encoded with consecutive frames spanning different focal distances defining a Group of Pictures (GOP), and/or spanning different hierarchical layers.

主权项

1. A multi-focus image data encoder, comprising:
an image frame mapping module including logic to map an image time stamp to an image focal distance associated with each of a plurality of image frames of a single scene, each image of the plurality associated with a unique image focal distance; a video encoding module including logic to encode the plurality of image frames as a time sequential series of an encoded video based on the image frame time stamps; and an electronic memory to store the encoded video.
