Abstract
A peak intensity level control device that controls a peak intensity level in a self light-emitting display module of an active matrix driving type is disclosed. The device includes: an average picture value calculation section that calculates an average picture value of display data to be supplied to the self light-emitting display module; a driving condition control section that controls, at a time of performing intensity-up driving with respect to the peak intensity level, a driving condition of the self light-emitting display module so as to be able to derive the peak intensity level suited for the average picture value; and a gamma change section that applies, at the time of performing the intensity-up driving with respect to the peak intensity level, a gamma change to the display data so as not to increase power consumption compared with driving with the peak intensity level of a standard value.
