Display device, picture signal processing method, and program

摘要

Provided is a display device including a display unit having luminescence elements that individually becomes luminous depending on a current amount. The luminescence elements are arranged in a matrix pattern. The display device includes an adjustment signal generator for generating an adjustment signal for adjusting an effective duty regulating a luminous time per unit time. The luminescence elements are luminous for the luminous time. The display device also includes a luminous time setter for setting the effective duty equal to or lower than an upper limit value provided for the effective duty to be set, according to picture information of an input picture signal, so that a total luminescence amount per unit time is limited, at which amount the luminescence elements of the display unit are luminous. The display device further include an upper limit value setter for changing the upper limit value of the luminous time setter, depending on the adjustment signal output from the adjustment signal generator based on an operation.
