Dynamic Compression Method for Use in Compressing Image Data

A method for dynamically compressing image data to fit within a predefined memory capacity of a memory buffer includes dividing the image data into a plurality of data bands; determining an average band memory size in the memory buffer for each data band of the plurality of data bands; compressing a...

Zusammenfassung:A method for dynamically compressing image data to fit within a predefined memory capacity of a memory buffer includes dividing the image data into a plurality of data bands; determining an average band memory size in the memory buffer for each data band of the plurality of data bands; compressing a current data band at a compression quality level; and adjusting the compression quality level for a next data band of the plurality of bans to be compressed based on the average band memory size and a compressed memory size of the current data band.
