Partitioning high resolution images into sub-images for display

摘要

Various embodiments provide techniques for partitioning high resolution images into sub-images for display. In at least some embodiments, the techniques can enable a device to display an image in its native resolution (e.g., the image capture resolution) even when the image exceeds a threshold image size for the device. In example implementations, techniques determine that a size of an image exceeds a threshold image size for a system. Further to some embodiments, the techniques can determine that the image is to be partitioned into multiple sub-images that can each be processed and reassembled to display the image. The sub-images can each be rendered by a graphics processing functionality (e.g., a graphics processing unit) and displayed on a display device to present a version of the image in its native resolution.

1. A computer-implemented method comprising:
determining, responsive to ascertaining that a size of a primary image exceeds a threshold image size for a system, that the primary image is to be partitioned into multiple sub-images; calculating a guide parameter to be used to size at least one of the multiple sub-images, the guide parameter being calculated as a mathematical function of both an image memory attribute of the system and a graphics memory threshold for the system; determining a first dimension for the at least one of the multiple sub-images based on the guide parameter; determining a second dimension for the at least one of the multiple sub-images based on an amount of graphics memory up to the graphics memory threshold available to generate the at least one of the multiple sub-images using the first dimension; and partitioning the primary image into the multiple sub-images.
