Abstract
A display unit includes: a liquid crystal display section displaying a series of original frame images and a series of interpolated frame images in a time-divisional manner, the interpolated frame images being generated based on the original frame images; a backlight emitting light intermittently; and a backlight control section controlling a first light-emission amount and a second light-emission amount of the backlight independently of each other, the first light-emission amount being an amount during a first period corresponding to a period for displaying the original frame images, and the second light-emission amount being an amount during a second period corresponding to a period for displaying the interpolated frame images.
Claims12
A display unit, comprising:
- a liquid crystal display section displaying a series of original frame images and a series of interpolated frame images in a time-divisional manner, the interpolated frame images being generated based on the original frame images;
- a backlight emitting light intermittently;
- a backlight control section controlling a first light-emission amount and a second light-emission amount of the backlight independently of each other, the first light-emission amount being an amount during a first period corresponding to a period for displaying the original frame images, and the second light-emission amount being an amount during a second period corresponding to a period for displaying the interpolated frame images;
- and
- a computing section determining, based on each of the original frame images, an amount of display light to be projected from a display surface of the liquid crystal display section in response to display of the original frame images on the liquid crystal display section,
- wherein the backlight control section controls the first light-emission amount and the second light-emission amount based on the amount of display light obtained by the computing section, and
- wherein the backlight control section decreases the first light-emission amount and increases the second light-emission amount when the amount of display light is increased, and increases the first light-emission amount and decreases the second light-emission amount when the amount of display light is decreased.

A display unit, comprising:
- a display section displaying a series of original frame images and a series of interpolated frame images in a time divisional manner, the interpolated frame images being generated based on the original frame images;
- a backlight emitting light intermittently;
- a display control section controlling a light-emission amount of the backlight during a period for displaying the original frame images to be a first total light-emission amount, and controlling a light-emission amount, and controlling of the backlight during a period for displaying the interpolated frame images to be a second total light emission amount, the first total light-emission amount being defined as a sum of a first basic light-emission amount corresponding to image information of the original frame images and a first offset light-emission amount, the second total light-emission amount being defined as a sum of a second basic light-emission amount corresponding to image information of the interpolated frame images and a second offset light-emission amount;
- and
- a computing section determining, based on each of the original frame images, an amount of display light to be projected from a display surface of the display section in response to display of the original frame images on the display section,
- wherein the display control section controls the first offset light-emission amount and the second offset light-emission amount independently of each other and based on the amount of display light obtained by the computing section, and
- wherein the display control section decreases the first offset light-emission amount and increases the second offset light-emission amount when the amount of display light is increased, and increases the first offset light-emission amount and decreases the second offset light-emission amount when the amount of display light is decreased.

A method of displaying, comprising:
- displaying, on a liquid crystal display section, a series of original frame images and a series of interpolated frame images in a time-divisional manner, the interpolated frame images being generated based on the original frame images;
- allowing a backlight to emit light intermittently, the allowing the backlight to emit the light intermittently including controlling a first light-emission amount and a second light-emission amount of a backlight independently of each other, the first light-emission amount being an amount during a first period corresponding to a period for displaying the original frame images, and the second light-emission amount being an amount during a second period corresponding to a period for displaying the interpolated frame images;
- and
- increasing the first light-emission amount and decreasing the second light-emission amount when an amount of background-light around the liquid crystal display section is increased, and decreasing the first light-emission amount and increasing the second light-emission amount when the amount of background-light is decreased.
