DISPLAY DEVICE, VIDEO SIGNAL PROCESSING METHOD, AND PROGRAM |
摘要 |
<p>There is provided a display device including a display unit having pixels, each of which includes a luminescence element that individually becomes luminous depending on a current amount and a pixel circuit for controlling a current applied to the luminescence element according to a voltage signal, where the pixels are arranged in a matrix pattern. The display device includes an average luminance calculator (200) for calculating average luminance for a predetermined period of the input picture signal, and also includes a luminous time setter (202) for setting an effective duty depending on the calculated average luminance by the average luminance calculator (200), the effective duty regulating for each one frame a luminous time for which the luminescence element is luminous. The luminous time setter (202) sets the effective duty such that a luminescence amount regulated by a preset reference duty and possible maximum luminance of a picture signal.</p> |
