Application: Description of image composition with hevc still image file format (Patent ID: US20230421794A1)
The patent filed by Canon Inc. describes a method for encapsulating an encoded bitstream representing images by providing descriptions of images and/or sub-image pictures, composing picture descriptions, and outputting the bitstream along with the composed picture description as an encapsulated data file. The method involves identifying portions of the bitstream representing images and/or sub-images, providing descriptions for composed pictures formed by these images, and outputting the encapsulated data file.
The patent also includes multiple claims related to a method, device, and computer-readable storage medium for reading an image file containing images or sub-images. The method involves obtaining descriptive metadata and initialization data for the images, obtaining a composite item associated with dependency lists and transformation parameters, and displaying a composition image based on this information. The claims cover various aspects such as transformation parameters for composition or cropping, item types indicating transformation, dependency lists, compliance with ISO standards, and the use of hardware processors and memory for executing the method. Overall, the patent focuses on a comprehensive method and system for reading and displaying images from an image file in a structured and efficient manner.
