Microsoft patents image compression tuned to your eyes and screen distance
Microsoft describes a method for compressing video or images by adjusting the algorithm to match a specific user's vision. The system uses data on how sensitive your eyes are to different levels of detail, along with how far away you are from the screen, to decide what visual information to keep and what to discard.
In the filing’s own words
Examples are disclosed relating to an approach for individualized image compression. In one example, an individual contrast sensitivity function (CSF) of a user is received from a remote computing system. A distance measurement indicating a distance between the user and a display of the remote computing system is received from the remote computing system. An image frame is generated. One or more parameters of a compression algorithm are modified based at least on the individual CSF of the user and the distance measurement. A compressed image frame is generated from the image frame using the compression algorithm based at least on the one or more modified parameters.
What exactly they claim (claim 1)
1. A computing system comprising: a logic subsystem; and a storage subsystem holding instructions executable by the logic subsystem to: receive, from a remote computing system, an individual contrast sensitivity function (CSF) of a user and a distance measurement indicating a distance between the user and a display of the remote computing system, wherein the individual CSF of the user indicates different contrast sensitivities of the user at different spatial frequencies; generate an image frame; modify one or more parameters of a compression algorithm based at least on the individual CSF of the user and the distance measurement, wherein the one or more parameters of the compression algorithm include values of a quantization table to be used by the compression algorithm to generate the compressed image, and wherein at least some of the values of the quantization table are modified to cause quantization of frequency coefficients at spatial frequencies where the user has lower contrast sensitivities, as specified by the individual CSF of the user, to a greater degree than frequency coefficients at spatial frequencies where the user has higher contrast sensitivities, as specified by the individual CSF of the user; and generate a compressed image frame from the image frame using the compression algorithm based at least on the one or more modified parameters.
