Abstract

Provided is a display driving circuit for driving a display panel. The display driving circuit includes: an interface configured to receive, from a sensor hub including an acceleration sensor, an acceleration sensing signal of the acceleration sensor, and a processor configured to: calculate a number of steps based on the acceleration sensing signal; generate sensing image data based on the number of steps; and control a display panel to display an image indicating the number of steps.
