Abstract | A method for intelligent data compression in a portable computing device ("PCD") is provided, the method comprising: determining a fixation point within an image frame by a fixation point sensor, wherein the fixation point sensor is configured to determine an area of user focus within a given image frame; sectoring the image frame into two or more sectors, wherein the two or more sectors comprises a fixation sector that includes the fixation point and one or more foveated sectors, each foveated sector does not include the fixation point, and each sector comprises a plurality of tiles; compressing the image frame such that the fixation sector is compressed according to a compression algorithm having a low compression factor and the one or more foveated sectors are compressed according to a compression algorithm having a high compression factor, wherein each respective tile within a particular foveated sector is subject to a different compression factor that is based on a distance between the fixation sector and the respective tile, each compression factor of a respective tile within a foveated sector having a magnitude that is assigned corresponding to the distance between the fixation sector and a respective tile; and storing the compressed image frame. |
