Classification: CPC G  Y | IPC G

Claim 0:
1. A current limiting circuit that receives a video signal for a display panel including pixels, and limits current consumption of the pixels, the current limiting circuit comprising:
a first gain calculation circuit that calculates a first gain for multiplying with the video signal, based on first power consumption that is power consumption of the pixels corresponding to the video signal;
a second gain calculation circuit that calculates a second gain for multiplying with the video signal, based on the first power consumption and a rate of change of the first power consumption;
a gain selection circuit that selects one of the first gain and the second gain as a gain by which the video signal is to be multiplied; and
a gain multiplication circuit that multiplies the video signal by the gain.
