摘要
Disclosed are techniques for optimizing visual light communication (VLC) processing performed at a mobile device. In an aspect, an image sensor of the mobile device having a rolling shutter captures a plurality of lines of an image frame, an image signal processor (ISP) coupled to the image sensor writes each line of the plurality of lines of the image frame into a dual port memory as each line of the plurality of lines of the image frame is received from the image sensor, and, for each line of the plurality of lines of the image frame, a VLC decoder of the mobile device reads a first line of the plurality of lines of the image frame from the dual port memory while the ISP writes a second line of the plurality of lines of the image frame to the dual port memory.
