System information (version)

OpenCV => 3.3 Operating System / Platform => ubuntu 16.04

Detailed description

I extracted frames from a video using ffmpeg.The image format is jpg.The folder containing the image files was 92MB.When I read it in a python list using opencv's imread the size in RAM is close to 3GB.Is this a bug in imread or what am i missing here.I could not find a solution in opencv answers as well.
