Signals are provided which allow colors in a wider color range than predetermined standards, which can be handled by apparatus according to such predetermined standards. A primary color converter converts first color signals having primary color points in a wider color range than the primary color points according to BT.709 into second color signals based on the primary colors according to BT.709. A photoelectric transducer converts the second color signals into third color signals according to photoelectric transducer characteristics defined in a numerical range wider than a range from 0 to 1.0 of color signals corresponding to a luminance signal and color difference signals according to BT.709. A color signal converter converts the third color signals into a luminance signal and color difference signals. A corrector incorporated in the color signal converter corrects the color difference signals into color difference signals.

Signal processing apparatus and method, and program

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 () for calculating average luminance for a predetermined period of the input picture signal, and also includes a luminous time setter () for setting an effective duty depending on the calculated average luminance by the average luminance calculator (), the effective duty regulating for each one frame a luminous time for which the luminescence element is luminous. The luminous time setter () sets the effective duty such that a luminescence amount regulated by a preset reference duty and possible maximum luminance of a picture signal.

Display device, picture signal processing method, and program

There is provided a display device provided with a display portion, in which pixels having a light-emitting element for self-light-emitting, and a pixel circuit for controlling a current applied to a light-emitting element according to a voltage signal are arranged in a matrix, provided with an average luminance calculation portion calculating an average of luminance of an input video signal, and a light-emitting time setting portion setting a real duty defined every one frame by which light-emitting time for light emitting of the light-emitting element according to a calculated average luminance, wherein the light-emitting time setting portion sets the real duty in such a way that a light-emitting amount defined by a standard duty set beforehand and a maximum luminance among those of a video signal, and a light-emitting amount defined by a real duty to be set and an average luminance become the same as each other.
